通过发送WM_GETTEXT命令获得EDIT中的信息

zzz要想获得其他程序edit控件中的信息，只能通过发送WM_GETTEXT消息才能成功，代码如下
Code
#include <windows.h>
BOOL CALLBACK EnumChildProc(HWND hWnd,LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
char className[]="notepad";
HWND hWnd=::FindWindow(className,NULL);
if(hWnd)
{
::EnumChildWindows(hWnd,EnumChildProc,0);
return 0;
}
MessageBox(NULL,"fail!","fail",MB_OK);
return 0;
}
BOOL CALLBACK EnumChildProc(HWND hWnd,LPARAM lParam)
{
char temp1[256],temp2[256];
::GetClassName(hWnd,temp1,255);
if(!::strcmp(temp1,"Edit"))
{
::SendMessage(hWnd,WM_GETTEXT,sizeof(temp2)/sizeof(char),(LPARAM)temp2);//EDIT的句柄，消息，接收缓冲区大小，接收缓冲区指针
::MessageBox(NULL,temp2,"get",MB_OK);
return 0;
}
::wsprintf(temp2,"classname: %s",temp1);
MessageBox(NULL,temp2,"cwnd",MB_OK);
return true;
}设定EDIT中的内容在上篇日志中：）
