在winXP中如何创建一个隐藏进程窗口（从任务栏）的进程？用CreateProcess函数？
/* CreateProcess initialization */
STARTUPINFO si;
PROCESS_INFORMATION pi;
memset(&si, 0, sizeof(si));
memset(&pi, 0, sizeof(pi));
si.cb = sizeof(si);
long ret;
// si.wShowWindow = SW_HIDE;
// hide process window.... // run in background..
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;
if (!CreateProcess(0, exe,
0, 0, 1, NORMAL_PRIORITY_CLASS, 0, 0, &si, &pi)) {
return;
}
//int prez = WaitForSingleObject(pi.hProcess, INFINITE);
//CloseHandle(pi.hProcess);

您可以尝试设置 dwFlags 成员="noreferrer">
STARTUPINFO结构为STARTF_USESHOWWINDOW，wShowWindow成员为SW_HIDE。这将使
CreateProcess()将 0 作为WinMain。但是，并非所有 Windows 应用程序都表现良好并使用此值来初始调用ShowWindow()。You can attempt to set the
dwFlagsmember of yourSTARTUPINFOstructure toSTARTF_USESHOWWINDOWand thewShowWindowmember toSW_HIDE.This will make
CreateProcess()pass 0 as thenCmdShowparameter ofWinMain. However, not all Windows application are well behaved and use this value to the initial call toShowWindow().不是您（新进程的创建者）将新进程注册到任务栏中。这是创建一个顶级窗口的新进程，该窗口决定是否位于任务栏中。该决定基于该顶级窗口的扩展样式，该样式由新进程决定。
换句话说，您必须在另一个进程中查看顶级窗口才能执行此操作。
It's not you, the creator of the new process, that registers the new process into the task bar. It's the new process that creates a top-level window that decides whether or not to be in the taskbar. This decision is based on the extended style of that top-level window, which is determined by the new process.
In other words, you'd have to poke at the top-level window in this other process in order to do this.
您可以找到与启动的进程关联的窗口（请参阅
FindWindow和EnumWindows），并调用ShowWindow函数与SW_HIDE。或者，您可以通过删除WS_EX_APPWINDOW并添加WS_EX_TOOLWINDOW来修改窗口的扩展样式。如果启动的进程遵循设置，最简单的方法仍然是使用第一个答案中所述的 STARTUPINFO 。
You can find the window associated with the started process (see
FindWindowandEnumWindows), and callShowWindowfunction withSW_HIDE. Alternatively you can modify the extended style of the window by removingWS_EX_APPWINDOWand addingWS_EX_TOOLWINDOW.The simplest way is still to use STARTUPINFO as described in the first answer, if the started process respects the setting.
