passing CString arguments to dll functions

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am hoping this is easy -- Is there an easy way to convert a CString to the type required for the dll calls (wchar_t *)?
I have tried a bunch of things but not found the magic code :)

		CString Label = "xx";

		ConvertedLabel = ??; // how to get the CString Label into a format to pass into functions?

		QP.DrawText(100, 500,  ConvertedLabel); // this  does not work.

Does anyone have a suggestion how to do this?  [we are using MSVC6]

Thanks

	Wendell, Can you try calling QP.DrawTextA - 'A' is for the Ansi string version. It should get you started. Have you tried using CStringW ? Here is some code that compiles and runs in an VS2010 MFC project. if (QP->UnlockKey(_T("<<< insert license key here >>>")) == 1) { int ret; QP->AddTrueTypeFont(L"Wingdings", 0); QP->SetOrigin(1); QP->DrawText(100, 20, L"Hello World"); QP->SetTextSize(18); ret = QP->DrawText(100, 500, _T("Hello world")); ret = QP->SaveToFile(_T("HelloFromDLL.pdf")); CStringW filename = L"f:\\downloads\\1.pdf"; ret = QP->LoadFromFile(filename, L""); delete QP; } Andrew.
