Thank you for viewing my question. I am building a project in Visual Studio 2010 using vb and .net. I have a Crystal Reports report that I'm trying to have auto export and open in PDF with a button click. Right now I am using Crystal Reports Viewer in my project which opens the report fine; However, I would like to have it only open in a pdf format. Is there a way to do this?
Note: I'm not here hunting for code. I'm wanting to learn, so if you could just guide me in the right direction, that will be great (if you don't want to provide code)!
Thank you for the help.

I'm using code from http://www.codeproject.com/Articles/14549/Crystal-Reports-To-PDF-converter-Without-Crystal-R
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Public Class clsCrystalToPDFConverter
Dim ConInfo As New CrystalDecisions.Shared.TableLogOnInfo
Dim oRDoc As New ReportDocument
Dim expo As New ExportOptions
Dim sRecSelFormula As String
Dim oDfDopt As New DiskFileDestinationOptions
Dim strCrystalReportFilePath As String
Dim strPdfFileDestinationPath As String
Public Function SetCrystalReportFilePath(ByVal CrystalReportFileNameFullPath As String)
strCrystalReportFilePath = CrystalReportFileNameFullPath
End Function
Public Function SetPdfDestinationFilePath(ByVal pdfFileNameFullPath As String)
strPdfFileDestinationPath = pdfFileNameFullPath
End Function
Public Function SetRecordSelectionFormula(ByVal recSelFormula As String)
sRecSelFormula = recSelFormula
End Function
Public Function Transfer()
oRDoc.Load(strCrystalReportFilePath) 'loads the crystalreports in to the memory
oRDoc.RecordSelectionFormula = sRecSelFormula 'used if u want pass the query to u r crystal form
oDfDopt.DiskFileName = strPdfFileDestinationPath 'path of file where u want to locate ur PDF
expo = oRDoc.ExportOptions
expo.ExportDestinationType = ExportDestinationType.DiskFile
expo.ExportFormatType = ExportFormatType.PortableDocFormat
expo.DestinationOptions = oDfDopt
oRDoc.SetDatabaseLogon("PaySquare", "paysquare") 'login for your DataBase
oRDoc.Export()
End Function
End Class
You'll need to set the variables to the specifics of your project obviously. These are more than likely the classes and methods you'll be wanting to use however. This should allow you to take your crystal reports viewer file and turn it into something opened by PDF
This works for me.
Dim orpt As CrystalDecisions.CrystalReports.Engine.ReportDocument
orpt = DirectCast(crvInvoice.ReportSource, CrystalDecisions.CrystalReports.Engine.ReportDocument)
orpt.ExportToDisk(ExportFormatType.PortableDocFormat, "PdfFileName.pdf")

Here's my recommendation that I think will pretty much solve most Open XML SDK issue. They have both a comparison tool and a code generation tool. Use thoughts to your advantage.
Create the document you want to see in Microsoft Word. Save It.
Open the document again, add a bookmark. Save it again, but under a different name.
Open the XML SDK comparison tool and select both documents. It'll show you the differences, and also will show you the sample .NET code that can be used to create the 2 documents. In this case, you'll focus on the differences in the code.
I'm trying to build a for-loop in Visual Basic that will go over each item in a sharepoint database list and stop it from inheriting permissions from its parent. I'm getting a Null Exception because my query object is null. I've searched and all the code snippets i found didnt define a value for the query and wrote the code exactly like i did, why is this a problem.
Imports System
Imports Microsoft.SharePoint.Client
Imports SP = Microsoft.SharePoint.Client
Module Module1
Sub Main()
Dim siteUrl As String = "https://cws1.conti.de/content/00009504"
Dim clientContext As New ClientContext(siteUrl)
Dim oList As List = clientContext.Web.Lists.GetByTitle("TestBI")
Dim query As CamlQuery
query.ViewXml = "<Where><Eq><FieldRef Name='Account' /><Value Type='Text'></Value></Eq></Where>"
Dim oListItems As ListItemCollection = oList.GetItems(query)
For numItems As Integer = 0 To 2
oListItems(numItems).BreakRoleInheritance(True, False)
Next
clientContext.ExecuteQuery()
End Sub
End Module
I've never programmed VB before and i'm not familiar with automating anything on Sharepoint so I would really appreciate any help.
you need to assign an instance of an object to the query variable before you can use it. Right now, you only declare a variable.
Change the line:
Dim query AS CamlQuery
to
Dim query AS new CamlQuery
Also, CamlQuery expects a full <View> tag. So change your CAML to <View><Query><Where><Eq><FieldRef Name='Account' /><Value Type='Text'></Value></Eq></Where></Query></View> and you should be good to go.
If you wish to retrieve all items from the list, use the CamlQuery.CreateAllItemsQuery() method.
Dim query AS CamlQuery = CamlQuery.CreateAllItemsQuery()
I need to save created object into Windows Registry and after reopening application to read it? I know how to save and read string but this is complex object.
Any idea?
You maybe want to use a XmlSerializer (or other serializers). It's easy to use, and the documentation is full of examples.
But why storing it in the registry?
Better use Application Settings and User Settings.
EDIT:
Instead of the registry, save your object to a file in the ApplicationData directory of the user. You can get the path to this directory with
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
Full example:
Imports System.IO
Imports System.Xml.Serialization
Module Module1
Public Class MySuperClass
Public Property MyString() As String
Public Property MyInt() As Int32
End Class
Public Sub Main(ByVal args() As String)
Dim myFolder = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData), "MyApplication")
If Not Directory.Exists(myFolder) Then
Directory.CreateDirectory(myFolder)
End If
Dim myFile = Path.Combine(myFolder, "MySettings.txt")
Dim o = New MySuperClass With {.MyString = "Hi!", .MyInt = 42}
Dim x = New XmlSerializer(GetType(MySuperClass))
Using sr = New StreamWriter(myFile)
' Save directly to file
x.Serialize(sr, o)
End Using
' for demonstrating purpose
o = Nothing
Using sr = New StreamReader(myFile)
' Load directly from file
o = CType(x.Deserialize(sr), MySuperClass)
End Using
End Sub
End Module
I have created a crystal report (cross tab). I'm not using any dataset, instead I used the wizard in crystal report to call an procedure from my Database schema
(Provider given is Microsoft OLEDB provider for oracle, after which I gave my DB credentials(i.e. schema, username, password) and selected the procedure and selected the columns I wanted to display in the report).
There are 5 parameters that I need to pass it from the front end to generate the report. While viewing the crystal report preview, by giving parameters, the report works fine.
Now i want to pass these 5 parameters from the front end(vb.net) to show the report in the CrystalReportViewer. Please suggest the code to write in aspx.vb file.
(PS:- I did go through other forums and found out some code, but all of them were giving some or the other error, so am posting one so that i can get the code specific to my requirement).
Thanks in advance..
I have gotten the report to work...
I wrote the code below:
Dim RptDocument As New ReportDocument
RptDocument.Load(Server.MapPath("rpt\Report.rpt"))
RptDocument.SetParameterValue("param1", Session("param1"))
RptDocument.SetParameterValue("param2", ddlparam2.SelectedValue)
RptDocument.SetParameterValue("param3", param3.text)
RptDocument.SetParameterValue("param4", param4.text)
RptDocument.SetParameterValue("param5", param5.text)
'Set login info
Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
Dim myTable As Table
For Each myTable In RptDocument.Database.Tables
myLogin = myTable.LogOnInfo
myLogin.ConnectionInfo.ServerName = "server name"
myLogin.ConnectionInfo.DatabaseName = ""
myLogin.ConnectionInfo.UserID = "userid"
myLogin.ConnectionInfo.Password = "pwd"
myTable.ApplyLogOnInfo(myLogin)
myTable.Location = myTable.Location
CrystalReportViewer1.ReportSource = RptDocument
Created a System DNS and had to add Oracle.DataAccess.dll to reference and a class file (with functions same as that in connectooracle.vb class file but with different name), also set up a connection in global.asax to refer to that class connection and using
Imports Oracle.DataAccess.Client instead of Imports System.Data.OracleClient (to avoid ambiguity)...
This somehow made it work and there might be some other solution for that..:)
(For ref:- Adding myLogin.ConnectionInfo.IntegratedSecurity = True gave me this error--
Logon failed. Error in File C:\DOCUME~1\Username\LOCALS~1\Temp\Report {1AG3DD86-141D-43YA-B6A2-AEDF3459AE49}.rpt: Unable to connect: incorrect log on parameters.)
This works for me and I'm using Visual Studio 2008 for this one since VS2010 doesn't have crystal engine for the reference.
First, make sure you have imported these two:
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Now, on my part I was using the odbc because as what I have noticed crystal report works fine with this and since we are working with odbc. So I did not include the login property on the report in my code. On the report just choose odbc connection.
Private Sub ReportViewer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim cryRpt As New ReportDocument
Dim str1 As String
Try
str1 = Title.str1
str2 =Title.str2
cryRpt.Load("c:\Program Files\Report\" & str2 & "")
Dim crParameterFieldDefinitions As ParameterFieldDefinitions
Dim crParameterFieldDefinition As ParameterFieldDefinition
Dim crParameterValues As New ParameterValues
Dim crParameterDiscreteValue As New ParameterDiscreteValue
crParameterDiscreteValue.Value = strStore
crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields
crParameterFieldDefinition = crParameterFieldDefinitions.Item("Store")
crParameterValues = crParameterFieldDefinition.CurrentValues
crParameterValues.Clear()
crParameterValues.Add(crParameterDiscreteValue)
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)
rptviewer.Cursor = Cursors.AppStarting
rptviewer.ReportSource = cryRpt
rptviewer.Refresh()
rptviewer.Cursor = Cursors.Default
Catch ex As Exception
MsgBox(ex.Message)
Me.Close()
ReportInterface.Show()
End Try
End Sub
I have a class that will get the data inputted by the user. But this will not work using stored procedure parameters.
please mark as accepted if it works for you
Thank You
Alright, so I need a method that traverses all the forms inside a VB.net project under Visual Studio 2008, and create an array of type form with references to all the forms inside it, so that the array looks like this (pseudocode)
FormsArray() = [Form1, Form2, Form3, Form4]
However, I don't have a clue as to how to begin.
You have to adjust the function to put the result of msgbox in a array
Public Sub getallforms(ByVal sender As Object)
Dim Forms As New List(Of Form)()
Dim formType As Type = Type.GetType("System.Windows.Forms.Form")
For Each t As Type In sender.GetType().Assembly.GetTypes()
If UCase(t.BaseType.ToString) = "SYSTEM.WINDOWS.FORMS.FORM" Then
MsgBox(t.Name)
End If
Next
End Sub
You must call the function from any form in the application like this (getallforms(me))
Here is how you would do this using Reflection, assuming that the class where you placed this code was in the same assembly that you wanted to iterate over. If not, then you'll need to change the Me.GetType().Assembly in the For Each loop into something else to account for loading the assembly in a different manner.
Dim Forms As New List(Of Form)()
Dim formType As Type = Type.GetType("System.Windows.Forms.Form")
For Each t As Type In Me.GetType().Assembly.GetTypes()
If t.IsSubclassOf(formType) = True Then
Forms.Add(CType(Activator.CreateInstance(t), Form))
End If
Next
Hey this is what I did to get the list of forms in my vb project, how ever this in not in code but you could write system.io code fragment to do just that.
open cmd prompt
go to project folder
run a dir /s/b *.designer.vb >> list.txt
use notepad or sublimetext and edit it to get the list ordered as you like it.
:) hope this helped!
I could not get this version to work:
Dim Forms As New List(Of Form)()
Dim formType As Type = Type.GetType("System.Windows.Forms.Form")
For Each t As Type In Me.GetType().Assembly.GetTypes()
If t.IsSubclassOf(formType) = True Then
Forms.Add(CType(Activator.CreateInstance(t), Form))
End If
Next
In VB2010 formType is always Nothing
So I dumped the formType line and simply modified your 'IF' statement to check the BaseType instead. Here is the New Version
Dim Forms As New List(Of Form)()
For Each t As Type In Me.GetType().Assembly.GetTypes()
If t.BaseType.Name = "Form" Then
Forms.Add(CType(Activator.CreateInstance(t), Form))
End If
Next
You need to either write a VS macro or an Addin.
In it, from a DTE or DTE2 instance, you can write:
Public Sub GetForms(ByVal host As DTE2)
Dim project As Project = host.ActiveDocument.ProjectItem.ContainingProject
For Each ce As CodeElement In project.CodeModel.CodeElements
If ce.Kind = vsCMElement.vsCMElementClass Then
Dim cl As CodeClass = CType(ce, CodeClass)
If cl.IsDerivedFrom("System.Windows.Forms) Then
'do something
End If
End If
Next
End Sub
2 options
I would load the actual project file into a XML reader. Then iterate all the nodes looking for all Form SubTypes and store the linked files in an array. If the name of file matches the name of the form class, you can create your FormsArray from that list. Otherwise you have to load each file and look for the public class definition of the file to get the list.
Using Reflection, examine the project using Assembly.GetTypes. Find all the System.Windows.Forms.Form Types and store them in a list. Then write out the Type.Name.
