Relative path to images in access reports - vba

It is my first time building a database and I wanted to share a solution to a problem I encountered.
My problem was that I wanted to show different images for each record in a report, but I also wanted to be able to move the database. This was a problem. I search in all the forums and all the different solutions didn’t work. I also found an article written by Microsoft saying that the only way is to either store the full path to the images or to store the image in the database. But this causes a problem if the database is moved, or storing the images in the database will take up a lot of storage space.
The problem is that the codes doesn’t work for each record in the report, the codes are for the entire report. So writing codes to find the backend and the image folder would result in displaying the first image in the report for all the records in that report.
However I discovered, when only storing the name of the image in a table, it would sometimes work (but it shouldn’t have, because I didn’t have the path) but when I restarted the database it would stop working. Investigating further I discovered that whenever you open the file browser it will store the path in some kind of memory. As long as the path to the images is stored in the memory it will be able to link the images to the path.
So my solution…
When the form, from where you access the reports is opened, the file browser is opened and the path to the images is pasted in (using codes to find backend and the image folder) and then the browser is closed. And this creates a link to the image names (stored in a table) with the path. And each different images will be shows for each different records in the report.
Not a pretty solution. Whenever the form is opened, you will see a flash of the file browser. But it gets the job done.
In the load form event:
`' this will find the backend and the image folder:
Dim filepath As String
Dim strBackEndPath As String
Dim lenPath As Integer
Dim i As Integer
Dim j As Integer
strBackEndPath = CurrentDb.TableDefs("yourTabeInBackend").Connect
j = InStrRev(strBackEndPath, "=") + 1
strBackEndPath = Mid(strBackEndPath, j)
BackPath = Left(strBackEndPath, InStrRev(strBackEndPath, "\"))
filepath = BackPath & "YourImageFolder\"
'this will open the folder browser and paste in the path and close it:
Dim f As Object
Set f = Application.FileDialog(msoFileDialogFolderPicker)
Dim varFile As Variant
Dim strPath As String
Dim fileName As String
With f
.InitialFileName = (filepath)
.AllowMultiSelect = False
SendKeys "{ESC}", True
f.Show
For Each varFile In .SelectedItems
Next varFile
End With
`

You can move the pictures to a subfolder of the folder of your database.
Then save the pictures' names like this:
Picture1.jpg
Picture2.jpg
etc.
When you run the application, obtain the path to the pictures:
PictureFolder = CurrentProject.Path & "\FolderName\"
Then the path to a picture will be:
PictureFolder & Me!PictureFileName.Value
When you "move" your database, move both the database file and the folder with the picture files with it.

yup, i just encountered same problem and i agree with what Richard_Ha said, but in my case i solve it with storing image path on textbox and its work..
first textbox name "fileimage_txt" and bound to list of image filename on table
second textbox name "image_path" with property
Source Control : =GetImagePath()
visible : No (if u dont want it get printed)
and image control with property
Source Control : =[path_txt] & [fileimage_txt]

Merge pdf files with VBA and Foxit

I use Foxit Phantompdf, the complete version and ACCESS.
In our program, we have to save multiple pdf files, some of them should be merged in single files when saved.
Here is the code I use;
Dim phApp As PhantomPDF.Application
Dim n1 As String
Dim n2 As String
n1 = "c:\Temp\F3769-190136-GROUPE OCÉAN.pdf"
n2 = "c:\Temp\f3769-190136-GROUPE OCÉAN- facture.pdf"
Set phApp = CreateObject("PhantomPDF.Application")
Dim phCreator As PhantomPDF.Creator
Set phCreator = phApp.Creator
***'Call phCreator.CombineFiles("c:\Temp\F3769-190136-GROUPE OCÉAN.pdf|c:\Temp\f3769-190136-GROUPE OCÉAN- facture.pdf", "c:\Temp\F3769-190136-GROUPE OCÉAN.pdf", COMBINE_ADD_CONTENTS)***
Call phCreator.CombineFiles("""c:\Temp\" & n1 & "|'" & n2 & """" & ", " & """c:\Temp\F3769-190136-GROUPE OCÉAN.pdf"""" &", COMBINE_ADD_CONTENTS)
phApp.Exit
When I try it with the complete files names (in bold) the code works perfectly.
However, when I try to use variables, I get a
"Argument not optional"
error.
Can somebody help me ?
Thanks
Your string definitions in call line is incorrect.
You have defined n1 and n2 with the c:\temp already, and in your string conversion you add this again. I do not know if this is the route cause to your issue.
Furthermore I do not know the actual needed syntax for this phcreator.combine()
But is it not possible using only:
call pHcreator.combine(n1 & "|" & n2, …
The 'Argument not option' might imply you should add another input to your pHcreator, I would guess it could have something to do with FOXIT's combine function page settings. Try adding a input variable integer at the end of the function maybe?
But the fact that it works when writing strings in clear text would maybe suggest that the string manipulations is not correct?
I'm not a vba professional, but interested in the outcome, working myself with Foxit and also want to combine with vba. I'm currently not using version 9 som I seem to be out of luck, and only upgrading it I know what I want to do is possible.
I tried it, but got the same error message. So I took advantage of the fact that the function works when the file names are in plain text. I copied the files to be merged in a temporary folder and rename them. The renamed files are the then used in the merge function. It works perfectly, but Foxit adds a table of content page, and I don't know, yet, how to remove it. Here is my solution:
Private Sub Command4_Click()
Dim addi As String 'file to be merged to main file
Dim princi As String 'main file
Dim phApp As PhantomPDF.Application
'A temporary folder, in this case c:\t2, should be present
'In this example c:\Temp is the working folder
addi = "c:\Temp\filetomerge.pdf" 'full path of file to be merged
princi = "c:\Temp\mainfile.pdf" 'full path of main file
'fadd,pdf and fmain.pdf are the temporay files used in Foxit's function
FileCopy addi, "c:\t2\fadd.pdf" 'temporary file to be merged in temporary folder
FileCopy princi, "c:\t2\fmain.pdf" 'temporary main file in temporary folder
'Merge action
Set phApp = CreateObject("PhantomPDF.Application")
Dim phCreator As PhantomPDF.Creator
Set phCreator = phApp.Creator
Call phCreator.CombineFiles("c:\t2\fmain.pdf|c:\t2\fadd.pdf", "c:\t2\fmain.pdf", COMBINE_ADD_CONTENTS)
phApp.Exit
'Save merged file in working folder under main file name
Kill princi
FileCopy "c:\t2\fmain.pdf", princi
'delete temporary files
Kill "c:\t2\fadd.pdf"
Kill "c:\t2\fmain.pdf"
End Sub

Best way to export an Icon Image from Access?

I have about 50 icon images (.ico) on an Access form, however I don't have them stored on a disk. I'd like to export them from Access onto a disk location.
I tried the suggested solution on this thread:
Access - Export images from Image controls in forms
I couldn't open the resulting file, probably because my images are (.ico) rather than (.png)
EDIT: I'm able to copy the icons into paint, save them as pngs, then use an online converter to convert them to icons. Pretty time consuming but it works.
You can use this code blow.
It will save the content of all image controls of the provided form to files in the same folder.
Beware that some image controls contain 'strange' binary formats which maybe can't be displayed properly by every tool.
Also you would have to take care to assign a correct file extension after exporting yourself.
Place the code in a new module, then open the form in design view and call it like this: SaveAllImageControls Forms("MyForm")
Public Sub SaveAllImageControls(ByRef sourceForm As Form)
Dim item As control
For Each item In sourceForm.Controls: Do
If item.ControlType <> acImage Then Exit Do
If IsNull(item.PictureData) Then Exit Do
Dim bArray() As Byte
bArray = item.PictureData
Dim filename As String
filename = Application.CurrentDb.Name & "-" & sourceForm.Name & "-" & item.Name & ".binary"
Dim fileNumber As Integer
fileNumber = FreeFile
Open filename For Binary As fileNumber
Put fileNumber, , bArray
Close fileNumber
Loop While False: Next item
End Sub
The simplest solution is probably to export all the ico files and then process them with ImageMagick. You can run something like
convert image.ico image.png
either as part of the code you linked to or as a plain one time call in a command prompt.

You can open PDFs in text editors to see the structure of how the PDF is written.
Using VBA I have opened a PDF as a text file and go to extract the text and save it as a string variable in VBA. I want to look through this text to find a specific element; a polyline (called sTreamTrain) and get the vertices of the polyline by using the InStr function.
When i add more vertices to the polyline I cannot seem to extract the text string of the pdf. I get the error 'Run time error 62' which I do not understand what it means or what about the PDF has changed to now have this error.
Attached (via the link) is a PDF that I can read (Document 15) and a PDF I cannot read (Document 16). I have checked in excel so see that the vertices are present in both files. Also there is a copy of my VBA script as a notepad document and also my excel file (but it is difficult to find in my excel file - the script is "Module 6" function called "CoordExtractor_TestBuild01()")
Link:
https://drive.google.com/open?id=1zOhwnFWZZfy9bTAxKiQFSl7qiQLlYIJV
Code snippet of the text extraction process below to reproduce the problem (given an applicable pdf is used):
Sub CoordExtractor_TestBuild01()
'Opening the PDF and getting the coordinates
Dim TextFile As Integer
Dim FilePath As String
Dim FileContent As String
'File Path of Text File
FilePath = "C:\Users\KAllan\Documents\WorkingInformation\sTreamTrain\Document16 - Original.pdf"
'Determine the next file number available for use by the FileOpen function
TextFile = FreeFile
'Open the text file in a Read State
Open FilePath For Input As TextFile
'Store file content inside a variable
Dim Temp As Long
Temp = LOF(TextFile)
FileContent = Input(LOF(TextFile), TextFile)
'Clost Text File
Close TextFile
End Sub
I would like someone to let me know what runtime error 62 is in this context and propose any workflows to get around it in future. Also, I would like to know whether there certain characters you cannot store as strings? - Perhaps these are included when I increase the number of vertices past a certain number.
Also I would prefer to keep the scrips quite simple and not use external libraries because I want to share the script when it is done so others can use it thus its simpler if it works without extra dependencies etc, however, any and all advice welcome since this is only the first half of this project.
Thank you very much.
According to the MSDN documentation, this error is caused by the file containing
...blank spaces or extra returns at the end of the file or the syntax
is not correct.
Since your code works sometimes on documents with very similar names and content to documents where it doesn't work, we can rule out syntax errors in this case.
You can clean up the file contents before processing it any further by replacing the code at the top of your macro with the one below. With this I can read and extract information from your Document16.pdf:
Sub CoordExtractor_TestBuild01()
'Purpose to link together the extracting real PDF information and outputting the results onto a spreadsheet
'########################################################################################
'Opening the PDF and getting the coordinates
Dim n As Long
Dim TextFile As Integer
Dim FilePath As String
Dim FileContent As String
'File Path of Text File
FilePath = "C:\TEST\Document16.pdf" ' change path
'Determine the next file number available for use by the FileOpen function
TextFile = FreeFile
'Open the text file in a Read State
Open FilePath For Input As TextFile
Dim strTextLine As String
Dim vItem As Variant
Line Input #1, strTextLine
vItem = Split(strTextLine, Chr(10))
' clean file of garbage information line by line
For n = LBound(vItem) To UBound(vItem)
' insert appropriate conditions here - in this case if the string "<<" is present
If InStr(1, vItem(n), "<<") > 0 Then
If FileContent = vbNullString Then
FileContent = vItem(n)
Else
FileContent = FileContent & Chr(10) & vItem(n)
End If
End If
Next n
'Clost Text File
Close TextFile
' insert the rest of the code here

How do you retrieve the file path from a checked list box that has multiple subfiles from different directories?

I've got a checked list box that populates files and subfiles from a selected location using a folder browser dialog. What I'm trying to accomplish is retrieve each location/directory of every checked item within that list. I'm using these locations as a spot to copy and paste new files into if that makes sense.
I should add that I'm new to coding, and I don't know how to do something as "complex" as this. This is also my first post and I apologize if this is an easier type question for you guys.
For Each file As IO.FileInfo In ListBox1.CheckedItems
Dim NewFileName As String = FindListBox2ItemThatContains(file.Name)
Dim lstfiles As String = Directory.GetFiles(FBD2.SelectedPath)
If NewFileName.Trim.Length > 0 Then
IO.File.Copy(file.FullName, IO.Path.Combine(FBD2.SelectedPath, "item parent folder", NewFileName.Trim), True)
End If
ProgressBar1.Increment(+1)
Next

Issue with pdf docs not showing up

We recently wrote some code for a client using the Aspose.pdf library, on my system the pdf in question opened fine and most of the merge fields were filled in (we don't have the exact list of merge fields that they do).
They're telling me that on their system, some documents take 2-4 mins to open while others don't open at all.
What could be a possible cause of the document not opening at all?
My code is below:
' Load form
Dim doc As Aspose.Pdf.Document = New Aspose.Pdf.Document(sTemplateDir & sDocName)
'Get names of form fields
Dim fields As Aspose.Pdf.InteractiveFeatures.Forms.Field() = doc.Form.Fields
Dim sField As String
Dim field As Aspose.Pdf.InteractiveFeatures.Forms.Field
If fields.Length > 0 Then
For Each field In fields
'Get name of field
sField = field.FullName
'If the merge field isn't valid then we'll just leave it and assume its a fill-in
If nMergeCol.Contains(sField) And Not IsNothing(sField) Then
field.Value = nMergeCol.Item(sField)
End If
Next
End If
This has been resolved! As we suspected, it was a problem with the client's Javascript within the pdf file. The problem was within the calculations the absolute value was being used (name.value). Once this was switched to the relative value (this.event.value) the pdf file began behaving correctly with the AsPose code.
