User scope in TestComplete
I call shell to run command in TestComplete:
function RunCommand(cmd, intWindowStyle, waitOnReturn)
{
var shell = new ActiveXObject("WScript.Shell");
if (intWindowStyle != null){
shell.Run(cmd, intWindowStyle, waitOnReturn || false);
} else {
shell.Run(cmd);
}
}Simply i list files and directories in C:\Windows\System32:
RunCommand("cmd /C \"dir C:\\Windows\\System32 > C:\\test.log\"");From log file C:\test.log, i get files and dirs:
2224 File(s) 941,726,810 bytes
80 Dir(s) 2,868,465,664 bytes free
But if run the command directly in command line window, i get different results:
2635 File(s) 1,222,264,966 bytes
88 Dir(s) 2,868,346,880 bytes free
You can see 400+ files and 8 directories less in TestComplete result. I thought TestComplete was running the command in a different account, but when i ran below command in TestComplete, it said it was running as administrator:
RunCommand("cmd /C \"whoami /user > C:\\user.log\"");
/*** Output in C:\user.log ***/

Hi Haiyangwhu,
It looks like you are using 64-bit Windows. 64-bit Windows have two System32 folders:
- %windir%\System32 - for 64-bit applications
- %windir%\SysWOW64 - for 32-bit applications
When a 32-bit application tries to access the %windir%\System32 folder, Windows redirects it to the %windir%\SysWOW64 folder for compatibility purposes. You can read more about this here:
File System RedirectorTestComplete is a 32-bit application, so it launches 32-bit cmd, which gets redirected to the SysWOW64 folder. The cmd you launch directly from Windows is 64-bit, so it accesses the "true" System32 folder. That's why you get different results.
The workaround to access the "true" System32 folder from a 32-bit application is to use the %windir%\Sysnative alias.
RunCommand("cmd /C \"dir C:\\Windows\\Sysnative > C:\\test.log\"");Note that this alias works only in 32-bit apps on 64-bit Windows. It does not work on 32-bit Windows and in 64-bit apps on 64-bit Windows.
Another solution is to launch 32-bit or 64-bit cmd depending on Windows bitness:
if (Sys.OSInfo.Windows64bit) {
strCommand = "%windir%\\Sysnative\\cmd /C \"dir %windir%\\System32 > C:\\test.log\"";
}
else {
strCommand = "cmd /C \"dir %windir%\\System32 > C:\\test.log\"";
}
RunCommand(strCommand);Hope this helps!
