helloworld问题（windows编程）

#include<windows.h>

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);

int WINAPI WinMain(HINSTANCE hinstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)

wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);

ShowWindow(hwnd,nCmdShow);
UpdateWindow(hwnd);

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

LRESULT CALLBACK WndProc(HWND hwnd,UINT message, WPARAM wParam, LPARAM lParam)

HDC hdc;
PAINTSTRUCT ps;
RECT rect;

switch(message)
{
case WM_CREATE:
MessageBox(NULL,"Creating... ...","HelloWinMessage:",MB_OK);
return 0;

case WM_PAINT:
hdc = BeginPaint(hwnd,&ps);
GetClientRect(hwnd,&rect);
DrawText(hdc,TEXT("Hello,Windows XP!"),-1,&rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);

}
这段源代码是《Windows下的C/C++高级编程》书上的源码，可我却编译不过（WinXP+VC 6.0），不知是什么原因，代码我对照过了，和书上一样！还有我觉得好像括号不匹配，可加了以后，编译器又报错！
本人初学windows编程，对你的帮助，小弟不胜感激！

你有没有建工程？Win32 Application --> A simple Win32 application


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

} // 这里少了括号

[beginnow]

没有几个错误
//wndclass.hInstance = hInstance; ->wndclass.hInstance = hinstance;
hwnd = CreateWindow(szClassName,TEXT("The HelloWin Program"),
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance, ->hinstance
NULL);

最后 WinMain()
{
} //写上

[a_b_c_abc11]

一个大小写输入错误
int WINAPI WinMain(HINSTANCE hinstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)

hinstance ->> hInstance


return msg.wParam;

} // 这里少了括号


其他没问题，已运行过。

谢谢各位的指点和帮助，是我不够细心导致了这个问题！哈哈，以后一定注意！

少了一个括弧。
建议lz使用这样的代码用复制粘贴，否则是没事找事。

lz,I have recompiled the source code for you, you can copy them to your source code file, then compile it in the console mode

cl ***.c user32.lib GDI32.lib

类似这种框架程序
不需要自己敲 反而容易落下东西
找找看有没有电子版的例子
或者直接在.net什么的里边建一个工程
它就提供出来
