InstallShield2015制作安装包----------卸载前结束执行中的进程

方法一：InstallShiel直接调用cmd命令来杀掉进程。　　　　

    //更新或卸载时先关闭应用程序
    sCmdLine=" /c taskkill /f /im "Frs.exe"";
    nResult=LaunchAppAndWait("cmd",sCmdLine ,LAAW_OPTION_HIDDEN|LAAW_OPTION_NOWAIT);

  备注：

　　1、命令行前 ，记得加上   /c 

　　2、LaunchAppAndWait()函数第一个参数“cmd”，还有另外一种方式。并不是很好用。

STRING scCmd;
STRING sCmdLine;

scCmd=WINDIR ^ "system32" ^ "cmd.exe";    
nResult=LaunchAppAndWait(scCmd,sCmdLine ,LAAW_OPTION_HIDDEN|LAAW_OPTION_NOWAIT);

    

方法二：来自网友写的一些代码。

prototype POINTER ArrayToPointer(BYREF VARIANT);
prototype NUMBER  ProcessEnd(STRING);
prototype BOOL    ProcessRunning(STRING);

// Kernel functions.

prototype NUMBER Kernel32.OpenProcess(NUMBER, BOOL, NUMBER);
prototype NUMBER Kernel32.TerminateProcess(NUMBER, NUMBER);

// Process information functions.

prototype NUMBER PSAPI.GetModuleFileNameExA(NUMBER, NUMBER, BYREF STRING,

//              extracted. The pointer to the actual data is then extracted
//              from the _SAFEARRAY pointer.
//
// Parameters:  structArray - Array variable.

调用方式如下：

    if ProcessRunning("Frs") then  
        MessageBox("Application "Frs" is running,will been killed ", INFORMATION);
        ProcessEnd("Frs");
    endif;
