I've got a Crystal Report which I made in CR2008, which I'm printing from my vb.net application. In this report, I have an image and a formula field.
The image formula (Under Format Graphic > Picture > Graphic Location is set to be the formula field called #imgLocation.
In my vb.net code, I have the following block to select the saved file path from the database, then fill #imgLocation with this value, to set the image that is being shown.
Try
Dim logoPath As String = ds.Tables(0).Rows(0).Item("reportLogoPath") & ""
If logoPath = "" Then
MessageBox.Show("No logo path has been defined in the System Settings. Please set " & _
"one and try again.", "Load Report Failed", MessageBoxButtons.OK)
Exit Sub
Else
cReport.DataDefinition.FormulaFields.Item(2).Text = Chr(34) & logoPath & Chr(34)
End If
Catch ex As Exception
errorLog(ex)
End Try
I've seen this working twice. The image I want replaced the placeholder image when I had FormulaFields.Item(2), but then I resized the image and it didn't work. I then changed the value of the index, and it worked with FormulaFields.Item(4), but again stopped working when I resized the image.
Why is the index changing, and what is the way around it?
I tried using the named parameter option, but FormulaFields.Item("#imgLocation") gave me an error of
Invalid Index
EDIT
As per #Bugs request, this is the report showing the correct string and image
Then, after deleting and re-saving the image (But in a slightly bigger size), the parameter was passed correctly still, but the placeholder image was shown instead.
This makes me think now that it's to do with image size, however, re-sizing it back to the original size still didn't show it again.
EDIT 2
Could it be do to with the fact that I'm loading a new form which contains the report viewer, rather than opening it from the same form?
cReport.RecordSelectionFormula = selectionFormula
Me.Cursor = Cursors.Default
Dim f As New frmReportViewer(con, cReport, 0)
f.Show()
Private Sub frmReportViewer_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Try
setFormSizes(Me, con)
Me.Location = New Point((Screen.PrimaryScreen.WorkingArea.Width / 2) - (Me.Width / 2), 10)
Me.Text = "Report Viewer"
Dim logOnInfo As New TableLogOnInfo()
Dim i As Integer
For i = 0 To cReport.Database.Tables.Count - 1
logOnInfo.ConnectionInfo.DatabaseName = "comm_db"
logOnInfo.ConnectionInfo.Password = "Acplus2016!"
cReport.Database.Tables.Item(i).ApplyLogOnInfo(logOnInfo)
Next i
cReport.VerifyDatabase()
crViewer.ReportSource = cReport
crViewer.ToolPanelView = CrystalDecisions.Windows.Forms.ToolPanelViewType.None
crViewer.Zoom(87)
Catch ex As Exception
errorLog(ex)
End Try
End Sub
Please note my answer is addressing the part regarding adding parameters. For the moment the no image available placeholder is proving difficult to resolve on my side.
To add a parameter please follow these steps:
Add a parameter within Crystal Reports called imageLocation:
After pressing OK you should have a parameter in your list like this:
The following code will pass a value to the parameter:
Dim cReport As New ReportDocument
cReport.Load("C:\Report.rpt")
If cReport.ParameterFields.Item("imageLocation") IsNot Nothing Then
cReport.SetParameterValue("imageLocation", "\\SAGE200FS\Sage\StockImages\sc002.jpg")
End If
reportViewer.ReportSource = cReport
This is the output (I have added the parameter onto the report):
Note that if you are passing parameters and they are shown on the report, make sure you don't have cReport.VerifyDatabase() in place. This often throws up a dialog box asking for the parameter values.
Screenshot of dialog box:
By not calling cReport.VerifyDatabase() this will stop the dialog box from showing.
Now through Crystal Reports you can set the Graphic Location using a parameter. To do this, add the parameter to the report and suppress the field (as you don't want to see it). Then you can add the Report Field as the location.
Add parameter to report and suppress:
Add Report Field as the Graphic Location for the OLE Object:~=
Run the report and input the parameter. This will change the image accordingly. See both screenshots:
SC001::
INT4303:
This however does not seem to work through VB. The ReportViewer does not handle the change of images. Instead you are left with the default image. I'm unsure why this is the case and I'm guessing it's a bug with Crystal. If anyone knows of why this happens, feel free to comment.
EDIT
After discussing the smaller points in chat, we seem to have worked out that the issue arose because of the file path. Saving it to the database as \\server\...\...\image.png was not displaying, but after changing it to Z:\...\...\image.png it has worked fine every time. It was because of the file path, all along.

Your task, the easy way:
make a new project
add a DataSet to this new project
open the DataSet, in the properties call it something sensible
Right click the surface, add a new datatable, name it Person
Right click the datatable, add a column, name it IC. Right click, add column, name it Name. Keep going until you added all the fields you want to track(email,phone,address1 etc)
save the DataSet
open the form
show the datasources window (view menu.. other windows)
expand the nodes til you can see Person
click the drop down next to Person, switch from DataGridview to Details
drag Person onto the form. Text boxes, labels etc appear. In the tray at the bottom more things appear
add a textbox to the form and call it searchTextBox
add a search button to the form, double click it, add this line of code to the click handler:
personBindingSource.Filter = '[ic] LIKE '" & searchTextBox.Text & "'"
If personBindingSource.Count = 0 Then MessageBox.Show("No records")
double click the form background to add a form load event handler, put this line of code:
If IO.File.Exists("data.xml") Then .ReadXml("data.xml")
switch back to designer, single click the form background and switch to event properties of the form, add a handler to the form closing event:
.WriteXml("data.xml")
That's it, you now have a program that will open, read and fill the DataSet with data from the data.xml file, it will search it when you type something in the ic box, the text boxes use databinding to show values automatically, and when you close the program it will save updates data. The only task now is to load the xml file with data.
When the textboxes were added to the form you should also have seen a bar appear across the top with some left/right controls in and a green plus. Click the green plus, type some data in, click it again, type more data. Navigating back, if you're adding new data, will commit the data. If you're looking at existing data, editing it then navigating will commit it
After you added some data, you can search for existing data using the search box. When you've searched for a single value it should be the only thing shown and the nav will show "1 of 1". To get back to the mode where all data is showing, put a single asterisk in the search box and hit search; it should show the number records in the top bar and you can scroll them with the arrows.
If you already have lots of data in a file, like you use in your question, you can read it in a loop (like you do in your question, except don't use that code exactly cos it has loads of errors) as a one time thing and assign it into the datatable, or you can manipulate it directly into being XML in a text editor. This is easy to do if you have a capable text editor but I'll not offer any particular advice on it in case you don't have a large amount of existing data. Ask a new question if you do
I have tried to find an answer to this already, but cannot find one that answers this question.
I have a Master Form which contains two panels. In the master Form I am trying to write a subroutine to handle the loading of a form into one of the panels.
One panel always contains the same form and the code which works for this is:
'Configure Toolbar Import
Dim toolbarHandler As _pnl_header = New _pnl_header()
toolbarHandler.Size = pnlHeader.Size
toolbarHandler.TopLevel = False
pnlHeader.Controls.Add(toolbarHandler)
toolbarHandler.Show()
The panel successfully shows the form _pnl_header as expected.
The second panel will change the displayed form depending on user input, so rather than having to write the above code for every eventuality i would like one Public Sub to handle them all...
I've started writing a sub along the lines of:
Public Sub LoadContentPanel(WhichForm As Form)
Try
Dim contentHandler As WhichForm = New WhichForm()
contentHandler.Size = pnlContent.Size
contentHandler.TopLevel = False
pnlContent.Controls.Add(contentHandler)
contentHandler.Show()
Catch ex As Exception
MsgBox("Unable to Handle Content Panel Change. Error: " & ex.Message, vbOKOnly + vbCritical, "Load Error")
End Try
End Sub
However this fails as 'WhichForm' is not defined - how is best to correct this? or is there a better alternative?
Thanks
Without going into what you are doing I can explain where the error comes from.
Here you declare argument variable WhichForm of type Form
Public Sub LoadContentPanel(WhichForm As Form)
. . . . .
Code is incorrect in the next declaration line. WhichForm is a variable and not a type. Hence
Dim contentHandler As WhichForm = New WhichForm()
is invalid at As WhichForm. Because after As you need a type name. If you did
Dim contentHandler As Form = New Form()
it would work.
It seems that all you need to do is remove Dim contentHandler As WhichForm... and rename argument WhichForm to contentHandler.
Currently, I am utilizing ActiveReports to implement a dynamic image via pathname into a report that is generating.
The Images are being automatically generated as .jpg to a server folder. The Active Reports module imports the files using this code.
Sub ActiveReport_ReportStart
Picture1.Image = System.Drawing.Image.FromFile("path\filename.jpg")
End Sub
The problem I am running into is that this report locks out the jpgs from being overwritten.
I am unsure what could be going wrong, but it seems that the report is still using the image files after the report has been generated.
Am I missing a "disconnect" code piece to ensure that an import doesn't allow for continued contact to the file?
I apologize if this is simple, but I can't find anything for this specific instance.
Thank you.
EDIT:
I attempted to get around the lockout by copying them into their own variable. But this didn't work either.
Sub ActiveReport_ReportStart
dim TempImage as Image = Image.FromFile("path\filename")
Picture1.Image = TempImage
End Sub
You can use "Using" block to make sure that the object of the image is disposed as soon as its usage is completed.
Using statement basically marks a boundary for the objects specified in the statement. So when code block using Using – End Using is exited either after normal execution or some exception cause, the framework invokes the Dispose method of these objects automatically.
Here is the suggested code which can be helpful for you in resolving the issue:
Private Sub SectionReport1_ReportStart(sender As Object, e As EventArgs) Handles MyBase.ReportStart
Dim img As Image
Using bmpTemp = New Bitmap("path\filename.jpg")
img = New Bitmap(bmpTemp)
End Using
Picture1.Image = img
End Sub
I was able to get this to work by creating a function that used the Graphics.FromImage method and disposed the original file.
Public Function GetImageFile(ByVal pathfn As String) As Image
Dim tempImg As Image = Image.FromFile(pathfn)
Dim tempBtm As New Bitmap(Width:=img.Width*CorrectFactor, Height:=img.Height*CorrectFactor, Format:=tempImg.PixelFormat)
Using g As Graphics = Graphics.FromImage(bm)
g.DrawImage(tempImg, Point.Empty)
End Using
tempImg.Dispose()
Return tempBtm
End Function
The item that would be placed in the report would be as follows.
Sub ActiveReport_ReportStart
Picture1.Image = GetImageFile("Path\Filename")
End Sub
I am running into problems with the passing of parameters to an externally created Crystal Reports XI report from the WinForms application I'm building in Visual Studio 2015 Community Edition. No matter what I try to do, the report doesn't seem to get the value unless I manually select it at the prompt (which shouldn't even be popping up) when the report is being displayed. I'm using the same code I've used in a previous application (although that one was built in VS2008), but I've tried a number of "alternate" versions of the code in my attempts to get this working. Here's the code that I'm currently using:

The report itself is built to use an XML file as the data source, which is dynamically created by this application. All of that works normally, and oddly enough, if I send the report directly to the printer, it seems to print correctly without prompting me. It's only a problem when I try to display the report through the CrystalReportViewer object.
Some of the things I've tried without success:
I've tried with and without calling the Clear() methods on the
Parameter.CurrentValues and ReportValues objects.
I've tried moving all of the parameter setting logic to after I set the
ReportSource of the CrystalReportViewer control (rptViewer.ReportSource)
I've tried using alternate Crystal Reports objects (ParameterFields instead of ParameterFieldDefinitions and ParameterField instead of ParameterFieldDefinition).
I've tried removing all of the "complicated" code and just using the SetParameterValue method (i.e., Report.SetParameterValue("PrintAll", True)
I've even tried creating different types of parameter fields in the report itself (String, Boolean, Number) and passing appropriate values for those datatypes.
If I walk through the code, it doesn't appear to error out anywhere, and everything looks like it's working just great until I get to the .rptViewer.RefreshReport() line in the With ReportViewer block. I've verified that all of the parameters and values have only the value I am "selecting" via the application by checking them every step up to that point, and it all looks exactly as I expect it to look.
But the application (via Crystal Reports) continues to prompt me for the value I just passed in the code. If I select the value in that prompt, the report does generate correctly based on the value I select, but no matter what I "pass" in the programming, the prompt always defaults to True.
Does anyone have any suggestions that I may have overlooked for how to get this parameter to correctly pass to the CrystalReportViewer control? Please let me know if you need any additional information or have any questions about what I've set up so far here. Thank you in advance.
Okay, so based on the information I found over on http://www.it-sideways.com/2011/10/how-to-disable-parameter-prompt-for.html, it seems that the RefreshReport method for the CrystalReportViewer control basically wipes out any parameters and/or log on information:
1. ) Do not invoke CrystalReportViewer.RefreshReport Method
This method will refresh the data for the report currently displayed
in the CrystalReportViewer control. The report will prompt for
parameters or logon info is necessary.
So, this method is not needed unless the same
CrystalDecisions.CrystalReports.Engine.ReportDocument object is
reused.
By commenting out that line of the code, I was able to prevent the parameter prompt from being displayed. The only issue I have after making that change is that, even though the zoom level is being set to 1 (page width), and when I run the project the CrystalReportViewer control even shows that it's correctly set in the status bar ('Zoom Factor: Page Width' is displayed), the report itself is not actually zoomed in to the page width.
With the RefreshReport method uncommented, if I manually provided the value for my parameter, it would display the report properly zoomed. If I add the zoom button to the control (.rptViewer.ShowZoomButton = True), I can manually choose the Page Width option, which then correctly "re-zooms" the report to the desired level, but it won't immediately display that way if the RefreshReport method is not called.
Regardless, I can spend some time trying to fight that now, but I finally have it properly setting, passing and displaying the results of my parameter. I hope this helps someone else running into this issue.
I have am writing a POS application, which requires to print invoice very often.
I need to send it directly to printer instead of viewing the print dialogue. Using Reportviewer_renderingcomplete, I can avoid seeing the report but I do not know how to avoid seeing the print dialogue box and print report without user intervention?
Thanks a lot.
Here is how you can do it:
Dim m_currentPageIndex As Integer
Private m_streams As IList(Of Stream)
Dim report As New LocalReport()
report.DataSources.Add(New ReportDataSource("testData", reportData.Tables(0)))
report.ReportEmbeddedResource = "ReportsLibrary.rptTestData.rdlc"
Dim deviceInfo As String = "<DeviceInfo><OutputFormat>EMF</OutputFormat><PageWidth>8.5in</PageWidth><PageHeight>11in</PageHeight><MarginTop>0.25in</MarginTop><MarginLeft>0.25in</MarginLeft><MarginRight>0.25in</MarginRight><MarginBottom>0.25in</MarginBottom></DeviceInfo>"
Dim warnings As Warning()
m_streams = New List(Of Stream)()
report.Render("Image", deviceInfo, CreateStream, warnings)
For Each stream As Stream In m_streams
stream.Position = 0
Next
Dim printDoc As New PrintDocument()
printDoc.PrinterSettings.PrinterName = "<your default printer name>"
Dim ps As New PrinterSettings()
ps.PrinterName = printDoc.PrinterSettings.PrinterName
printDoc.PrinterSettings = ps
printDoc.PrintPage += New PrintPageEventHandler(PrintPage)
m_currentPageIndex = 0
printDoc.Print()
Where PrintPage defined as follows:
' Handler for PrintPageEvents
Private Sub PrintPage(sender As Object, ev As PrintPageEventArgs)
Dim pageImage As New Metafile(m_streams(m_currentPageIndex))
' Adjust rectangular area with printer margins.
Dim adjustedRect As New Rectangle(ev.PageBounds.Left - CInt(ev.PageSettings.HardMarginX), ev.PageBounds.Top - CInt(ev.PageSettings.HardMarginY), ev.PageBounds.Width, ev.PageBounds.Height)
' Draw a white background for the report
ev.Graphics.FillRectangle(Brushes.White, adjustedRect)
' Draw the report content
ev.Graphics.DrawImage(pageImage, adjustedRect)
' Prepare for the next page. Make sure we haven't hit the end.
m_currentPageIndex += 1
ev.HasMorePages = (m_currentPageIndex < m_streams.Count)
End Sub
This is an interesting walkthrough by Microsoft: Printing a Local Report without Preview.
It's a different approach from yours because it prints directly a report without using ReportViewer and RenderingComplete event.
In order to not display PrintDialog box you must set printDoc.PrinterSettings.PrinterName with your default printer name.
Maybe you can store this value in a user configuration file.
It is actually far more simple than you would have imagined.
Within your form, include a "PrintDocument" component from the Toolbox.
Within your code behind, you will want to call the following method on your newly added component.
PrintDoc.Print()
The documentations state that the Print() "Starts the document's printing process". It will automatically begin printing the default set printer.
As tezzo mentioned, to set the Printer manually you can use the following snippet:
PrintDoc.PrinterSettings.PrinterName = "YourPrinterNameHere"
PrintDoc.PrinterSettings.PrinterName "gets or sets the name of the printer to use" as according to documentation. And if you need any further help, check out this video.
Please note however that video does not mention how to print "silently". It is just a good reference for beginners to see how the Print Components work together.
