AV When Exporting To PDF

iolaltd · March 2005

I'm getting an AV when I Load a report, save to pdf, exit and re load the report. The AV is occuring on the following line of my code,

((TfrxMemoView*)frxReport->FindObject("Memo4"))->Text = cmbProducts->Items->Strings[cmbProducts->ItemIndex];

And in fact, ((TfrxMemoView*)frxReport->FindObject("Memo4")) = NULL the second time my code runs.

The AV doesn't occur if I set frxPDFExport1->ShowDialog to false though (but then the user can't choose a directory to save the file to)!!

Any ideas anyone?

Thanks,

Andy

OK, looks like I'm talking to myself again

I've sussed this out and I'm not sure if it constitutes a bug or not! It could (and probably will) be pushed into the "Intended Behaviour" pile.

Basically, I load a report using the following,

frxReport->LoadFromFile("Data\\99\\PartInfo.qha");

Set up some titles and ->ShowReport

If the user decides to Export the report and uses the Save As dialog then FastReports is actually changing the Current Directory to the one the user selects. So, when I next load my report, it doesn't load (and I didn't check that it loaded correctly but I probably should have!),

frxReport->LoadFromFile("Data\\99\\PartInfo.qha");

My current directory isn't what it was!

Bug or Intended Behaviour? I know where I'll put my money

Open/Save dialogs always change the current directory. You shouldn't use relative path when loading/saving your reports.

Agreed. Having looked into this I can confirm that this is the case. After developing for 12+ years I can't believe I haven't encountered it before.

Apologies for wasting posting space
