Hi,
see

If you are looking to debug a problem with your Xojo code using MBS Xojo
DynaPDF Plugin, we can help with our trace feature.
Dim pdf As New MyDynapdfMBS
pdf.TraceFile = SpecialFolder.Desktop.Child("dynapdf.txt")
Once you put the TraceFile assignment there, the plugin will open the file and
start writing log messages until the PDF is object is done. The output may look
like this:
SetLicenseKey
CreateNewPDFWfile
file: /Users/cs/Desktop/Create PDF.pdf
Result: true
SetDocInfoW
DInfo: 4
Text: "My first Xojo output"
Result: true
SetPageCoords
value: 1
Result: true
Append
ClearPageGraphics
Result: true
SetFontW
Name: "Times"
Style: 1
Size: 40.000000
Embed: true
CP: 39
Result: 0
WriteFTextW
Align: 1
Text: "My first Xojo output!"
Result: true
EndPage
ClearPageGraphics
Result: true
CloseFile
ClearPageGraphics
MyInitProgressProc
ProgType: 1
MaxCount: 1
MyProgressProc
ActivePage: 1
Result: 0
MyProgressProc
ActivePage: 1
Result: 0
Result: true
PDFDestructor
Now you see more than you may be calling directly. You see the file path used
for creating the PDF with CreateNewPDF function. Then we call SetDocInfo to set
the subject field for the PDF. We set page coordinate system and append a page,
which implicitly clears page graphics. Next we set a font and write something
and you see all the details like the code page 39, which is unicode. We close
the page, which clears page graphics again in case you used it. We close the
file and save it, which invokes optionally the progress events until the
destructor runs finally and ends the trace file.
If you build a complex PDF and you call thousands of DynaPDF functions, this
log may help you to find the errors by looking for error messages or result
codes here.
Sincerely
Christian
