Hello Everybody !

Here can you have a look on my OnPaint method :

/**************************

* OnPaint *

**************************/

void OnPaint(HDC hdc)

{

int dpi = 96;

double pageWidth = CT4UDLL_PDF::getInstance().Get_PageWidth();

double pageHeight = CT4UDLL_PDF::getInstance().Get_PageHeight();

Bitmap* PDFImage = new Bitmap(int(pageWidth/10),int(pageHeight/10));

Graphics* PDFGraphics = Graphics::FromImage(PDFImage);

HDC PDFhdc = PDFGraphics->GetHDC();

bool Res = CT4UDLL_PDF::getInstance().RenderPDFFilePage(NULL,CT4UDLL_PDF::getInstance().Get_FileHandle(),dpi,1);

Status St = PDFGraphics->DrawImage(PDFImage,0,0);

};

When starting the project (VC++), St equals to "ObjectBusy".

Could you please tell me why and the right way to render my PDF page on the screen ?

Thanks a lot !
