How to print multi pages in one task using ClassLibrary(MSVC)?

We want to print all images in one directory one by one, could we print all the pages at one time?

We are using Lead tools 15 ClassLibrary, Visual Studio .net 2005.

Thanks in advance.

Do you mean you want to print more than one image on the same printer page? If yes, please see these forum posts:

If you mean something else, please explain it in more details.

I mean print image1 on page 1, image2 on page2...
but print all the pages in one print job

something like(it can't work)

//Begin a print job

LBitmapBase MyBitmap;  
LPrint MyPrint;
 
//start page1
MyBitmap.Load(TEXT("C:\\Image1.cmp"));
MyPrint.SetBitmap(&MyBitmap);
//print page1
HDC hdcPrinter = MyPrint.Print(NULL, 0, 0, 0, 0, FALSE);
EndPage(hdcPrinter);
StartPage(hdcPrinter);
//start page2
MyBitmap.Load(TEXT("C:\\Image2.cmp"));
MyPrint.SetBitmap(&MyBitmap);
//print another page
MyPrint.Print();

//end the print job

The second MyPrint.Print();
is not using the same HDC of the first Print() command, this causes the second image to be printed to a different job.

Instead, you should pass the second print command like this MyPrint.Print(hdcPrinter);

Tell me if this solves the problem for you.

Thank you very much, Adam! It works very well.

The correct code is:

    //Begin a print job

    LBitmapBase MyBitmap;  
    LPrint MyPrint;

    //start page_1
    MyBitmap.Load(TEXT("C:\\Image_1.cmp"));
    MyPrint.SetBitmap(&MyBitmap);
    //print page_1
    HDC hdcPrinter = MyPrint.Print(NULL, 0, 0, 0, 0, FALSE);
    EndPage(hdcPrinter);

    //start page_2
    StartPage(hdcPrinter);
    MyBitmap.Load(TEXT("C:\\Image_2.cmp"));
    MyPrint.SetBitmap(&MyBitmap);
    //print page_2
    MyPrint.Print(hdcPrinter, 0, 0, 0, 0, FALSE);
    EndPage(hdcPrinter);
    //...
    //start page_n
    StartPage(hdcPrinter);
    MyBitmap.Load(TEXT("C:\\Image_n.cmp"));
    MyPrint.SetBitmap(&MyBitmap);
    //print page_n
    MyPrint.Print(hdcPrinter);

    //end the print job
