弹出窗口时, 很诡异

#include<windows.h>

BOOL CALLBACK EnumWndProc(HWND,LPARAM);

int WINAPI WinMain(HINSTANCE hInst,HINSTANCE hPrev,PSTR szCmd,int iCmd)
{
    EnumWindows(EnumWndProc,0);

    return 0;
}

BOOL CALLBACK EnumWndProc(HWND hWnd,LPARAM lParam)
{
    DWORD procId;
    char szBuffer[128];

    GetWindowThreadProcessId(hWnd,&procId);
    wsprintf(szBuffer,TEXT("%d"),procId);
    MessageBox(NULL,szBuffer,TEXT("process Id"),MB_OK);

    return FALSE;
}

#include<windows.h>

BOOL CALLBACK EnumWndProc(HWND,LPARAM);

int WINAPI WinMain(HINSTANCE hInst,HINSTANCE hPrev,PSTR szCmd,int iCmd)
{
    EnumWindows(EnumWndProc,0);

    return 0;
}

BOOL CALLBACK EnumWndProc(HWND hWnd,LPARAM lParam)
{
    DWORD procId;
    char szBuffer[128];

    GetWindowThreadProcessId(hWnd,&procId);
    wsprintf(szBuffer,TEXT("%d"),procId);
    MessageBox(NULL,szBuffer,TEXT("process Id"),MB_OK);

    return FALSE;
}

那个, 用c写, 没问题, 我用RadAsm写, 弹出的窗口很奇怪.., 大哥, 你帮忙看下, 谢谢哈

   

弹出来的窗口, 成这样子了, 我把wsprintf这个函数给屏蔽后, 就没问题, 是不是, 我的wsprintf函数格式, 没写正确?
