初学WINAPI抄了个程序HELLOWIN现在正常运行,我现在想把进程遍历程序放在HELLOWIN里发现不会,怎么办
//modify base on hellowin.cpp#include <Windows.h>
#include <TlHelp32.h>
#include <iostream>
LRESULT CALLBACK WndProc (HWND,UINT, WPARAM,LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,PSTR szCmdLine,
int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("hellowin");
HWND hwnd;
MSG msg;
WNDCLASS wndclass;
wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;
if(!RegisterClass(&wndclass))
{
MessageBox(NULL,TEXT("This program requires Windows NT!"),szAppName,MB_ICONERROR);
return 0;
}
//RegisterClass(&wndclass);
hwnd = CreateWindow(szAppName, //window class name
TEXT("hellowin"),//window caption
WS_OVERLAPPEDWINDOW,//window style
CW_USEDEFAULT,//initial x position
CW_USEDEFAULT,//initial y position
CW_USEDEFAULT,//initial x size
CW_USEDEFAULT,//initial y size
NULL,//parent window handle
NULL,//window menu handle
hInstance,//program instance handle
NULL);//creation parameters
ShowWindow(hwnd,iCmdShow);
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:
return 0;
case WM_PAINT:
hdc = BeginPaint(hwnd,&ps);
GetClientRect(hwnd,&rect);
DrawText (hdc,TEXT("win7hello!!!!"),-1,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);
EndPaint(hwnd,&ps);
return 0 ;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd,message,wParam,lParam);}
以上是HELLOWIN
我想插入的代码是
PROCESSENTRY32 pe32;
pe32.dwSize=sizeof(pe32);
int count=0;
HANDLE hProcessSnap=::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
BOOL bMore=::Process32First(hProcessSnap,&pe32);
while (bMore)
{
count++;
//printf("\n%20S%10d\n",pe32.szExeFile,pe32.th32ProcessID);
if(wcscmp(pe32.szExeFile,TEXT("smss.exe")) == 0)
{
//system("pause");
}
bMore=::Process32Next(hProcessSnap,&pe32);
}
请问应该怎么改HELLOWIN,让 DRAWTEXT的“WIN7HELLO”变成“SMSS。EXE”
非常感谢
