高分就教ShellExecute的问题

[Ice1]

1、请问如何取得一个ShellExecute的句柄。


2、我ShellExecute (NULL,"open","iexplore.exe",page,NULL,SW_SHOWNOACTIVATE);发现还是窗口还是在最前面弹出了。不知道怎么回事。

我试了,就ie不行,

可以使用 CreateProcess 然后取得该进程的主窗口句柄

请问如何取得？我是初学者。谢谢了

[Ice1]

取得句柄不可以用FindWindow,因为标题不一样。

[Kudeet]

1 ShellExecute本来就返回一个句柄
2 要隐藏用CreateProcess

[iamwiner]

2.可能是IE的问题,我换了个别的程序,就没有被激活.

[auly403]

SW_SHOWNOACTIVATE 改成SW_HIDE 看看

[iamwiner]

那是隐藏老兄,人家要打开但不激活.

PROCESS_INFORMATION pi;
STARTUPINFO si;
memset(&si,0,sizeof(si));
si.cb=sizeof(si);
si.wShowWindow=SW_HIDE;
si.dwFlags=STARTF_USESHOWWINDOW;
BOOL fRet=CreateProcess(NULL,"notepad.exe",NULL,NULL,FALSE,NULL, NULL,NULL,&si,&pi);

ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
if(CreateProcess("c:\\winnt\\notepad.exe", NULL,

想取得ShellExecute返回的窗口句柄。。。。说错了

[Ice1]

laiyiling(陌生人☆VCFANS)给的好象也是隐藏哦

也没有得到ShellExecute返回的窗口句柄。

我想是作的是不影响当前的窗口的。但也显示，不是隐藏。

帮你顶一下,要给分啊.^_^

// 变通办法， 最小化到任务栏:
ShellExecute (NULL,"open","iexplore.exe",page,NULL, SW_MINIMIZE);

[Ice1]

// 变通办法， 最小化到任务栏:
ShellExecute (NULL,"open","iexplore.exe",page,NULL, SW_MINIMIZE);


这个我也想过了。但是我想关闭以前窗口的时候显示出来。

取不到窗口的句柄，没法显示...........

[qrlvls]

并非所有窗口都可以隐藏

[qrlvls]

可以使用 CreateProcess 然后取得该进程的主窗口句柄
