That are famous QuickReport's bugs, and one of the reasons why Borland
discontinued cooperation with them.
Go to their web site and see if some patches are available.
Vladimir.

Hi all,
I'm using QReport to print variable bitmaps.
Everything is fine for the first time, the printout ( preview) is ok.
If I'm calling the function for the next time, the second page is corrupted
( black).
The third time everything is black, including a static logo.
I checked my bitmaps on a normal canvas before and after the printout,
everything ok.
Some ideas or suggestions?

Attached the code:
//----------------------------------------------------------------------
// defintion of the list
template <class T> class SeaTList :public TList
{
public:
__property T* Items[int Index] = {read=GetItem, write=PutItem};
T* First() {return (T*)TList::First();};
T* Last() {return (T*)TList::Last();};
void Add(T* Item){TList::Add(Item);};
protected:
T* GetItem(int Index) {return (T*)Get( Index);};
void PutItem(int Index, T* Item) {TList::Put(Index, Item);};
};
SeaTList<Graphics::TBitmap>* BitmapList;
//--------------------------------------------------------------------------
-
void __fastcall TFormQuickReportGraphic::QuickRep1NeedData(TObject *Sender,
bool &MoreData)
{
MoreData = ( iBitmapListIndex < iPagesCount);
}
//--------------------------------------------------------------------------
-
void __fastcall TFormQuickReportGraphic::DetailBand1BeforePrint(
TQRCustomBand *Sender, bool &PrintBand)
{
QRMainImage->Picture->Bitmap = BitmapList->Items[iBitmapListIndex];
iBitmapListIndex++;
PrintBand = true;
}
//--------------------------------------------------------------------------
-
void __fastcall TFormQuickReportGraphic::QuickRep1BeforePrint(

{
iPagesCount = BitmapList->Count;
iBitmapListIndex = 0;
}

I'm now creating the QReport form every time and delete it after the
printout.
Than it works.

Well, don't be so sure  I also create QReport form dynamically
every time and still have problems. I do not know how is it possible
but the system crashes less when I assign BMP's than JPG's.
TQRImages can sometimes be viewed in preview and sometimes not.
In both cases it can be printed like a black rectangle or invisible
(better behaivor - to save toner at least :)
Good luck.
