C语言版

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


BOOL CALLBACK EnumChildProc(HWND hwnd,LPARAM lParam)
{
    char text[1024];
    GetWindowText(hwnd,text,1024);
    printf("%s\n",text);
    return 1;
}
int main()
{
    HWND hWnd;
    char *str="资源编辑器";
    hWnd=FindWindow(NULL,str);
    if(hWnd==0){
        printf("not find\n");
        return 0;
    }
    EnumChildWindows(hWnd,EnumChildProc,NULL);
    return 0;
}

程序完成的功能都是一样的  查找指定窗口标题名为 资源编辑器 并获取指定窗口子窗口文字的功能
但是汇编能找到窗口
C语言版的确找不到窗口
