初学WINAPI抄了个程序HELLOWIN，我现在编了一个进程遍历的方法,放在HELLOWIN里发现不对，怎么办

TCHAR* findprocess() //新写的方法
{
    PROCESSENTRY32 pe32;
    pe32.dwSize=sizeof(pe32);
    int count=0;
    HANDLE hProcessSnap=::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    BOOL bMore=::Process32First(hProcessSnap,&pe32);
        while (bMore)
        {
            count++;
        if(wcscmp(pe32.szExeFile,TEXT("smss.exe")) == 0)
        {
            break;
            return TEXT("smss.exe");
        }
            bMore=::Process32Next(hProcessSnap,&pe32);
        }
        return 0;
}
想把这个方法加到HELLOWIN里边
LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
    TCHAR* findproc = this.findprocess();//<<<<<<<<<<<<<<<THIS  这里有错
    HDC hdc;
    PAINTSTRUCT ps;
    RECT rect;
    switch(message)
    {
    case WM_CREATE:
            return 0;

    case WM_PAINT:
        hdc = BeginPaint(hwnd,&ps);
        GetClientRect(hwnd,&rect);

        DrawText (hdc,findproc,-1,&rect,    //<<<<<<<<<<<<<<<<<<<<<<<<<想把遍历的返回值代入这里发现不得
            DT_SINGLELINE|DT_CENTER|DT_VCENTER);
            EndPaint(hwnd,&ps);
        return 0 ;
怎么办
