程序可以正常运行，为什么就是不显示窗口呢，

#include<windows.h>
#include<stdio.h>

LRESULT CALLBACK winSunProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
);

int WINAPI WinMain(
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmline,
int nShowCmd
)
{

WNDCLASS wc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wc.hCursor = LoadCursor(NULL,IDC_CROSS);
wc.hIcon = LoadIcon(NULL,IDI_ERROR);
wc.hInstance = hInstance;
wc.lpfnWndProc = winSunProc;
wc.lpszClassName = "SUNXIN";
wc.lpszMenuName = NULL;
wc.style = CS_HREDRAW|CS_VREDRAW;
RegisterClass(&wc);

HWND hwnd;
hwnd =CreateWindow("SUNXIN","WANGWENQUAN",
WS_OVERLAPPED,0,0,800,600,NULL,NULL,hInstance,NULL);

ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);

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

LRESULT CALLBACK winSunProc(
HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam
)
{
switch(uMsg)
{
case WM_CHAR:
char szchar[20];
sprintf(szchar,"char code is%d",wParam);
MessageBox(hwnd,szchar, "char",0);
break;
case WM_LBUTTONDOWN:
MessageBox(hwnd,"111111","22222222",0);
HDC hdc;
hdc=GetDC(hwnd);
TextOut(hdc,10,10,"laji",5);
case WM_PAINT:
HDC Hdc;
PAINTSTRUCT ps;
Hdc =BeginPaint(hwnd ,&ps);

TextOut(Hdc,40,40,"wangwen",strlen("wangwen"));
EndPaint(hwnd,&ps);
break;
}
return 0;
}

窗口过程里的默认项你没写帮你写上了也有注释 #include<windows.h> #include<stdio.h> LRESULT CALLBACK winSunProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam ); int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmline, int nShowCmd ) { WNDCLASS wc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH); wc.hCursor = LoadCursor(NULL,IDC_CROSS); wc.hIcon = LoadIcon(NULL,IDI_ERROR); wc.hInstance = hInstance; wc.lpfnWndProc = winSunProc; wc.lpszClassName = "SUNXIN"; wc.lpszMenuName = NULL; wc.style = CS_HREDRAW|CS_VREDRAW; RegisterClass(&wc); HWND hwnd; hwnd =CreateWindow("SUNXIN","WANGWENQUAN", WS_OVERLAPPED,0,0,800,600,NULL,NULL,hInstance,NULL); ShowWindow(hwnd,SW_SHOWNORMAL); UpdateWindow(hwnd); MSG msg; while(GetMessage(&msg,hwnd,0,0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return msg.wParam; } LRESULT CALLBACK winSunProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam ) { switch(uMsg) { case WM_CHAR: char szchar[20]; sprintf(szchar,"char code is%d",wParam); MessageBox(hwnd,szchar, "char",0); break; case WM_LBUTTONDOWN: MessageBox(hwnd,"
