Hwnd

[Amon Ra]

how do i convert an HWND to a string LPCTSTR?
thanks

[Megatron]

LPCTSTR lpBuff;
wsprintf( lpBuff, "%d", hWnd);
// lpBuff now contains hWnd

[Amon Ra]

cool thanks..also
is there a way to achieve what this does in VB:

cnt = GetProp(hwnd, "C" & hwnd) 

in C++, or do i have to use strcat?
thanks

[Amon Ra]

basivcally, can i put 2 strings together with "&" ? without using strcat?

strcat(char *dest,char *source) returns a pointer to dest so it can be used in functions , just like you want.

char tmp[20];
memset(tmp,0x0,sizeof(tmp));
strcpy(tmp,"C");
cnt = GetProp(hwnd, strcat(tmp,"hwnd") );

thanks..one more thing...what is the equivalent to this: (in VB)

ObjPtr(iwp) 

in C++?

is it

&iwp //? 

thanks

If you're using C++ strings, then you can use the + operator.

Bear in mind that it won't do type conversion to strings for you, you need to define your own operators if you want that (or use a stringstream):

#include <sstream>

using namespace std;

string somecode() {
    ostringstream oss;
    int y = 5;

    oss << "Hello " << y;

    return oss.str();
}

As for ObjPtr, yep. & is the address-of operator, and its counterpart is the * dereferencing operator.
