case WM_CREATE:
//创建普通按钮

"普通按钮",
BS_PUSHBUTTON|WS_CHILD|WS_VISIBLE,

可能是什么原因

可能是应该把倒数第三个参数设置为NULL吧

#include "windows.h"
#include "pro2.h"

long WINAPI WndProc(HWND hWnd,UINT iMessage,UINT wParam,LONG lParam);

if(!InitWindowsClass(hInstance))
return FALSE;

return FALSE;
while(GetMessage(&Msg,NULL,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}

break;
case WM_DESTROY:

break;

return DefWindowProc(hWnd,iMessage,wParam,lParam);
}
return 0;
}

if(!hWnd)
return FALSE;

return TRUE;
}

改了还是不行啊

还请大家帮我看看哈

是不是代码有问题？

hWndPush=CreateWindow("BUTTON", "按钮", WS_VISIBLE|WS_CHILD,0,0,50,20,
hWnd, (HMENU)ID_bta1, hInst, NULL);
ShowWindow(hWndPush,SW_SHOW);

非常感谢，谢谢你,不过我试了一下，还是不行

pro2.h的代码是：

#define IDB_PUSHBUTTON 10
#define IDB_DEFPUSHBUTTON 11
#define IDB_RADIOBUTTON 12
#define IDB_AUTORADIOBUTTON 13
#define IDB_CHECKBOX 14
#define IDB_AUTOCHECKBOX 15
#define IDB_GROUPBOX 16
#define IDB_GROUPBUTTON 17

楼主可以把你的主函数一起贴出来?

什么意思啊？

框架有问题,用win32api向导直接生成框架(选第三项),把我给你那句写在程序相同的位置.注意那个ID号,也可以先把它设为空
