Use BiPrint.dll from .NET Without Register Ocx File.

[wectan]

Refer to TIFF C# DLL sample, we can using the DllImport to GetNumberOfImagesInTiffFile (BiTiff.dll), LoadTiffIntoDIB (BiTiff.dll), RotateDIB90 (BiDib.dll) and so on. However, there is not sample of printing like BiPrintSetup, PrepareToPrint, PrintDIBPage and so on.

I try the following thing below but get the error - Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

[DllImport("BiPrint.dll")]
public static extern int BiPrintSetup(string PrinterName, bool ShowDialog);
[DllImport("BiPrint.dll")]
public static extern short PrepareToPrint(int hwnd, string ImageName, short maxPage, short numCopies, bool DisplayNameAttribute, bool CenterVerticalImage, bool CenterHorizontalImage, bool ScalePage, bool ConvertCtoB, bool StretchPage, bool AllPage, bool UseDPI, bool NotDispCancel);

BiPrintSetup(printDialog.PrinterSettings.PrinterName, false);
PrepareToPrint(hwnd, _filename, maxPage, 1, false, true, true, true, false, false, false, false, false);


Do you have sample in C#.NET or Vb.NET like TIFF C++ Sample.exe that just using BIDIB.dll,BiDisp.dll, BiPrint.dll, BiTiff.dll and not using any ocx, AxInterop.BIPRINTLib.dll, Interop.BIPRINTLib.dll. We are required to implement these thing without required register ocx files.

Hello,

The PrepareToPrint function has different parameters you declared. Here is your definition:

[DllImport("BiPrint.dll")] public static extern short PrepareToPrint(
int hwnd,
string ImageName,
short maxPage,
short numCopies,
bool DisplayNameAttribute,
bool CenterVerticalImage,
bool CenterHorizontalImage,
bool ScalePage,
bool ConvertCtoB,
bool StretchPage,
bool AllPage,
bool UseDPI,
bool NotDispCancel);

You used the parameters of the PrepareToPrint method of the BiPrint.ocx. The parameter list of the PrepareToPrint function in the BiPrint.dll is different:

int CALLBACK PrepareToPrint(HWND hWnd, HDC hPrnDC, LPGPRINT lpPrint, LPSTR lpImgName, UINT nMaxPage);

If you want to use the BiPrint.dll you have to use the correct parameter list (including the GPRINT structure).
For more information about parameters please check the documentation or C++ sample. The C++ sample uses only the TIFF SDK dlls for printing so you can check the parameter lists in using.
