Is possible to print variables values to Debug without specifying their types?-CodePudding

I'm printing the value of variables to DebugView.

There is any 'easier' way to print their value other than manually specifying the % VarTYPE

Currently doing it this way:

WCHAR wsText[255] = L"";
wsprintf(wsText, L"dwExStyle: %??? lpClassName: %??? lpWindowName: %??? ...", dwExStyle, lpClassName, lpWindowName, dwStyle, X, Y, ...);
return CreateWindowExA(dwExStyle, lpClassName, lpWindowName, dwStyle, X, Y, nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam);

It doesn't necessarily need to be wsprintf, being able to print it without needing to manually specify each parameter type would help!

CodePudding user response：

Yes use string streams, they're more safe then wsprintf too (buffer overruns). And for unknown types you can overload operator <<.

#include <Windows.h>
#include <string>
#include <sstream>

int main()
{
    DWORD dwExStyle{ 0 };
    std::wstringstream wss;
    wss << L"dwExtStyle : " << dwExStyle << ", lpClassName: "; // and more....
    OutputDebugString(wss.str().c_str());
}

std::ostream& operator<<(std::ostream& os, const your_type& value)
{
    os << value.member; // or something
    return os;
}
