error C2660: 'new' : function does not take 3 parameters

[Crystal]

Can anybody tell me why I am getting this error for the following line: graphics = new Graphics(hdcPrint); For your information, this is my function: // this function is for OTCDialog: OK button // It uses GDI to send image to a printer void OTRDialog::OnPrintFrom() { DWORD size; HDC hdcPrint; DOCINFO docInfo; ZeroMemory(&docInfo, sizeof(DOCINFO)); docInfo.cbSize = sizeof(DOCINFO); docInfo.lpszDocName = "GdiplusPrint"; // Create a PRINTDLG structure, and initialize the appropriate fields. PRINTDLG printDlg; ZeroMemory(&printDlg, sizeof(PRINTDLG)); printDlg.lStructSize = sizeof(PRINTDLG); printDlg.Flags = PD_RETURNDC; // Display a print dialog box. if(!PrintDlg(&printDlg)) { printf("Failure\n"); } else { // Now that PrintDlg has returned, a device context handle // for the chosen printer is in printDlg->hDC. StartDoc(hdcPrint, &docInfo); Graphics* graphics; StartPage(hdcPrint); graphics = new Graphics(hdcPrint); Image image(L"My_report.bmp"); graphics.DrawImage(&image, 5, 0, 360, 410); // Create a string. WCHAR string[256]; wcscpy(string, L"Sample Text"); // Initialize arguments. Font myFont(L"Arial", 6); PointF origin(20.0f, 5.0f); SolidBrush blackBrush(Color(255, 0, 0, 0)); // Draw string. graphics.DrawString(string, wcslen(string), &myFont, origin, &blackBrush); delete graphics; EndPage(hdcPrint); EndDoc(hdcPrint); DeleteDC(hdcPrint); } if(printDlg.hDevMode) GlobalFree(printDlg.hDevMode); if(printDlg.hDevNames) GlobalFree(printDlg.hDevNames); if(printDlg.hDC) DeleteDC(printDlg.hDC); }

How many parameters does the constructor for Graphics take? Sounds like your giving it less than the number required.

It takes exactly what she is giving it - a HDC. Christian I am completely intolerant of stupidity. Stupidity is, of course, anything that doesn't conform to my way of thinking. - Jamie Hale - 29/05/2002

1. Why does graphics have to be a pointer ? I seem to recall GDI+ does not like having new called on things in C++ ( new in C# is a totally different beast ), because it forces you to use it's .Clone methods instead. 2. Once you fix this, you'll get errors because you're using the . instead of the -> for the graphics object ( as it's a pointer ). Christian I am completely intolerant of stupidity.

DEBUG_NEW defines a new operator that takes three parameters to catch memory leaks when _DEBUG is also defined. Redefine it to use the non-debug new. Or, use the scope resolution operator ( :: ) before new to use the default C++ version.

[Ed Gadziemski]

Try this: graphics = ::new Graphics(hdcPrint); The problem is that an MFC generated define, DEBUG_NEW, defines a "new" operator that takes three parameters. It only applies for a debug build; if you do a release build your program should work. You can undefine DEBUG_NEW so that debug builds also work. Or, as shown in the example code above, you can use the scope resolution operator ( :: ) before new to use the default C++ version.
