It is not possible to assign a const char value to a unit of type LPCWSTR (C++, how can this be solved?)

[Piotr Kostrzewski]

Good evening. Here's my current code snippet:
#include <Windows.h>
#include <gdiplus.h>

#pragma comment(lib, "Gdiplus.lib")

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wPARAM, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR szCmdLine, int iCmdShow) {
static const char ClassName[] = "YangaImageBrowser";
WNDCLASSEX wc;
MSG msg;
HWND hwnd;

Gdiplus::GdiplusStartupInput gdiStartup;
ULONG_PTR gdiToken;

Gdiplus::GdiplusStartup(&gdiToken, &gdiStartup, NULL);

wc.cbClsExtra = 0;
wc.cbSize = sizeof(WNDCLASSEX);
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
wc.hInstance = hInstance;
wc.lpfnWndProc = WndProc;
Line28 wc.lpszClassName = ClassName;
wc.lpszMenuName = NULL;
Gdiplus::GdiplusShutdown(gdiToken);
return msg.wParam;
}
And here is my description of the error: (in Polish)

Błąd (aktywny) E0513 nie można przypisać wartości typu "const char *" do jednostki typu "LPCWSTR" Nasza Przeglądarka Zdjęć C:\Users\ACER\Desktop\ImageBrowser\Nasza Przeglądarka Zdjęć\Main.cpp 28
Any idea?
Have a nice weekend.

static const char ClassName[] = "YangaImageBrowser";

You want to remove the "const" there because WNDCLASSEX doesn't allow const assignments (since the classname is mutable and you're passing a pointer to a const in your case which is immutable).

Not really sure why you didn't look up the Microsoft documentation for WNDCLASSEX because it's all in there, including requirements to register nonstandard classes.

That's not right. It would seem UNICODE is defined somewhere, since it wants a wide string, not narrow. Remove the define or use static const wchar_t ClassName[] = L"YangaImageBrowser";.

Remove the define or use static const wchar_t ClassName[] = L"YangaImageBrowser";.

Thank you very much.
Using const wchar_t helped.
Have a nice weekend.
