char array to LPCTSTR conversion in c

Question

Does anyone know how to convert a char array to a LPCTSTR in c?

Edit:

For more reference, I need to add an integer to a string then convert that string to LP

Answer 1

It is an old classical question. I use it in UNICODE.

char *pChar = "My Caption of My application";
    WCHAR wsz[512];
    swprintf(wsz, L"%S", pChar);
    SetWindowText(hWnd,         // ウィンドウまたはコントロールのハンドル
        wsz   // タイトルまたはテキスト
    );

I'm not sure if you figured something out in the end but I had the same problem and following worked well for me:

int  comPortNum = 5;
char comPortName[32];
sprintf((LPTSTR)comPortName, TEXT("\\\\.\\COM%d"), comPortNum);
HANDLE h = CreateFile(comPortName,other arguments);
