推荐答案

SetForegroundWindow 的使用等方法重点设置有很多限制。如果你真的希望确保，即启动过程将接收焦点，我建议您使用以下本机（非托管）功能

Usage of SetForegroundWindow and other methods of setting of focus has a lot of restrictions. If you really want to be sure, that the started process will receive focus I recommend you to use following native (unmanaged) functions

SystemParametersInfo (SPI_GETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)&dwLockedTimeout, 0);
SystemParametersInfo (SPI_SETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)0,
                      SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);

在流程启动和恢复

SystemParametersInfo (SPI_SETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)&dwLockedTimeout,
                      SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);

在最后。 ;像

at the end. A call like

WaitForInputIdle (pi.hProcess, 5000);

程序开始后和 SPI_SETFOREGROUNDLOCKTIMEOUT 可也是有帮助的，如果你将不得不立即

after the program start and before restoring of SPI_SETFOREGROUNDLOCKTIMEOUT can be also helpful if you will have problems with immediate
