LibreOffice Writer API - Cursors and text selection / replacement from VB6 - api

I have been attempting to replace Office OLE in a vb6 application with LibreOffice.
I have had some success, however, I am falling short trying to search for text, then create a cursor based on the text that was found, then insert an image at that cursors point in the document.
I have been able to piece together working code that will allow me to search for text, replace text and insert an image, however, I cannot seem to figure out how to create a cursor that will allow me to insert an image at the pace where the text is that I have found . In the provided example, the [PICTUREPLACEHOLDER] text in the document.
Has anyone ever done this before and do they have any suggestions how I can create a cursor that will allow me to specify where the image will be inserted.
I have included the code for the VB6 test app so you can see the source code to see how its currently working.
Any suggestions would be very much appreciated.
Please Note - this is experimental code - very rough and ready - not final code by a long shot - just trying to figure out how this works with LibreOffice Writer.
To run this, you will need to create an empty vb6 app with a button.
You also need LibreOffice installed.
Many thanks
Rod.

Extract specific data points from pdf. Getting "Class not registered" error

Visual Basic CInt error

I am trying to make a function that looks at an image, and return the X pixel value.
When i run the code, it throws an error on the Int1=CInt(Xdim) line, saying "Type Mismatch (10080)"
If i hard-code the value i am testing into Xdim, it works fine.
Function ImgXDim(filename As String) As Integer ' Finds the X dimension in pixels of a loaded image
Dim objShell As Object
Dim objFolder As Object
Dim objFile As Object
Dim ImgSize As String
Dim Int1 As Integer
Dim Xdim As String
Dim strarray() As String
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace(MacroDir & "\PICS\")
Set objFile = objFolder.ParseName(filename)
ImgSize = objFile.ExtendedProperty("Dimensions") ' Returns string of "700 x 923"
strarray = Split(ImgSize, " x ") ' Split into 2 strings of "700" and "923"
Xdim = CStr(strarray(0)) ' Force Xdim to be a string of "700"
Int1 = CInt(Xdim) ' Convert Xdim to an integer
ImgXDim = Int1 ' Return Integer
End Function
First check if value can be converted to an integer:
If IsNumeric(Trim(Xdim)) then
Int1 = CInt(Xdim)
else
'for debug purposes
MsgBox ("XDim non-numeric or empty")
End If
Ok, i couldnt find what character was causing the issue, so i used this loop of code to pull out only numbers, and it seems to work.
For X = 1 To Len(Xdim)
If IsNumeric(Mid(Xdim, X, 1)) = True Then
holder = holder & Mid(Xdim, X, 1)
End If
Next X
Here the WIA version:
Function ImgXDim(filename As String) As Long
Dim imgWIA as New WIA.ImageFile 'Early Binding needs a reference to Windows Image Aquisition Library in VBA-Ide->Tools->References
'Dim imgWIA as Object 'Late Bound Version
'Set imgWIA = CreateObject("WIA.ImageFile")
imgWIA.LoadFile MacroDir & "\PICS\" & filename
ImgXDim = imgWIA.Width ' use .Height for height
End Function
As you see, just three lines of code and returns a long, not a string that needs parsing.
Useful functions for resize, rotate and more.
Also useful if you want to display Tiffs in a picture control (page by page) and more.

Object variable or With block variable not set (Error 91)

I have the following code:
Sub AddSources()
Dim pubPage As Page
Dim pubShape As Shape
Dim hprlink As Hyperlink
Dim origAddress() As String
Dim exportFileName As String
exportFileName = "TestResume"
Dim linkSource As String
linkSource = "TestSource2"
Dim hyperLinkText As TextRange
For Each pubPage In ActiveDocument.Pages
For Each pubShape In pubPage.Shapes
If pubShape.Type = pbTextFrame Then
For Each hprlink In pubShape.TextFrame.TextRange.Hyperlinks
If InStr(hprlink.Address, "http://bleaney.ca") > 0 Then
hyperLinkText = hprlink.Range
origAddress = Split(hprlink.Address, "?source=")
hprlink.Address = origAddress(0) + "?source=" + linkSource
hprlink.Range = hyperLinkText
End If
Next hprlink
End If
Next pubShape
Next pubPage
ThisDocument.ExportAsFixedFormat pbFixedFormatTypePDF, "C:\" + exportFileName + ".pdf"
End Sub
I am getting the "Object variable or With block variable not set (Error 91)" error on the line with hyperLinkText = hprlink.Range. When I debug I can see that hprlink.Range does have a value. Any thoughts what I'm doing wrong?
As I wrote in my comment, the solution to your problem is to write the following:
Set hyperLinkText = hprlink.Range
Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

How to prevent link formatting from changes when editing link using VBA?

I'm currently using the following code to update all the links in my application:
Sub AddSources()
Dim pubPage As Page
Dim pubShape As Shape
Dim hprlink As Hyperlink
Dim origAddress() As String
Dim exportFileName As String
exportFileName = "TestResume"
Dim linkSource As String
linkSource = "TestSource2"
For Each pubPage In ActiveDocument.Pages
For Each pubShape In pubPage.Shapes
If pubShape.Type = pbTextFrame Then
For Each hprlink In pubShape.TextFrame.TextRange.Hyperlinks
If InStr(hprlink.Address, "http://bleaney.ca") > 0 Then
origAddress = Split(hprlink.Address, "?source=")
hprlink.Address = origAddress(0) + "?source=" + linkSource
End If
Next hprlink
End If
Next pubShape
Next pubPage
ThisDocument.ExportAsFixedFormat pbFixedFormatTypePDF, "C:\" + exportFileName + ".pdf"
End Sub
The problem is that when I update the links, they lose their formatting. How can I preserve the formatting of the hyperlink? I tried looking at the Copy and Paste methods, but it seems like what I would really need is Paste Special, which doesnt exist on the Range property on the Hyperlink object.
Try adding the following lines to capture the color and underline and then set it back after the address change
Sub AddSources()
Dim pubPage As Page
Dim pubShape As Shape
Dim hprlink As Hyperlink
Dim origAddress() As String
Dim exportFileName As String
Dim undline AS Long
Dim clr AS Long
exportFileName = "TestResume"
Dim linkSource As String
linkSource = "TestSource2"
For Each pubPage In ActiveDocument.Pages
For Each pubShape In pubPage.Shapes
If pubShape.Type = pbTextFrame Then
For Each hprlink In pubShape.TextFrame.TextRange.Hyperlinks
If InStr(hprlink.Address, "http://bleaney.ca") > 0 Then
undline = hprlink.Range.Font.Underline
clr = hprlink.Range.Font.Color
origAddress = Split(hprlink.Address, "?source=")
hprlink.Address = origAddress(0) + "?source=" + linkSource
hprlink.Range.Font.Color = clr
hprlink.Range.Font.Underline = undline
End If
Next hprlink
End If
Next pubShape
Next pubPage
ThisDocument.ExportAsFixedFormat pbFixedFormatTypePDF, "C:\" + exportFileName + ".pdf"
End Sub

Join more powerpoint presentations into one new presentation keeping the originally slide-layout in Lotusscript

I am working on a project that joins two or more pp presentations into one new presentation.
The selection of the original pp presentations is in a webbased Lotus Notes xPage and after the submit, Lotusscript talkes to the OLE Powerpoint object.
Adding the slides into the new Presentation in the right order is no problem.
The problem is that after the adding the original connection with the slides Template(s) is lost.
To solve this I found the next codesnippet:
Sub joiner()
Dim sFileName As String
Dim oDonor As Variant
Dim otarget As Variant
Dim i As Integer
On Error GoTo errhandler
Set otarget = ActivePresentation
Do While sFileName <> ""
Set oDonor = Presentations.Open(Environ("USERPROFILE") & "\Desktop\joiner\" & sFileName, msoFalse)
For i = 1 To oDonor.Slides.Count
oDonor.Slides(i).Copy
With otarget.Slides.Paste(otarget.Slides.Count + 1)
.Design = oDonor.Slides(i).Design
.ColorScheme = oDonor.Slides(i).ColorScheme
End With
Next i
oDonor.Close
Set oDonor = Nothing
sFileName = Dir()
Loop
End Sub
I have to declare the presentations oDonor and oTarget as a Variant because lotusscript doesn't understand Dim oTarget As Presentation
This is probably the reason why the code returns a typemismatch error at:
.Design = oDonor.Slides(i).Design
My questions are:
Am I doing the join the right way or is there a better solution?
Is there a solution for the typemismatch error?
*ps: The result presentation doesn't have to be editable, so maybe it is not necessary to add templates.
Update 04-10-2012:
The next code solves the template problem.
What still is missing now is the background image used by some slides.
See: https://stackoverflow.com/questions/12731691/how-to-export-a-backgroundimage-of-a-slide-to-the-filesystem
Dim oDonor As Variant
Dim h As Integer
Dim thetmplt As Variant
Dim thetmpltname As String
Dim thetmpltnew As Variant
Dim thetmpltnamenew As String
Set oDonor = PPApplication.Presentations.Open(tempdirectory +
jobid+CStr(filenamearray (i)),False,False,False)
thetmplt = oDonor.TemplateName
Call oDonor.SaveAs(tempdirectory +jobid+CStr(i)+ thetmplt+".pot" ,5, -1)
For h = 1 To oDonor.Slides.Count
Dim oTargetSlide As Variant
oDonor.Slides(h).Copy
Set oTargetSlide = newPres.Slides.Paste()
Next
Dim theubound As Variant
theubound = oDonor.Slides.Count
ReDim thearray(1 To k + theubound) As Variant
For k = k To k + oDonor.Slides.Count-1
thearray(k) = k
Next
Call newPres.Slides.Range(thearray()).ApplyTemplate(tempdirectory +
jobid+CStr(i+thetmplt+".pot")
oDonor.Close
Set oDonor = Nothing
This is just a hunch, but try:
Dim oTargetSlide as Variant
Set oTargetSlide = otarget.Slides.Paste(otarget.Slides.Count + 1)(1)
With oTargetSlide
.Design = oDonor.Slides(i).Design
.ColorScheme = oDonor.Slides(i).ColorScheme
End With
