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.

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
