ShellExecute is not working

Hi,

I need to get the Domain name of machine. As we use "whoami" command in cmd.exe to find the domain name, I did the same using code. but somehow the command.out file is not generating on my machine.

I wrote following code:

std::string currentUserInfo("");

std::string sCmdStr("WHOAMI>E:\command.out");  //output e.g. domainname\username

std::wstring wstr(sCmdStr.begin(), sCmdStr.end());

LPCWSTR lpCmdStr = wstr.c_str();

//windows func to execute command

ErrorCode error = kFailure;

ShellExecute(NULL, NULL, L"cmd.exe", lpCmdStr, NULL, SW_HIDE);

//this code will get user info from command.out

using std::ifstream;

ifstream ifs("E:\command.out");

std::getline(ifs, currentUserInfo);

ifs.close();

/**************************************************************************************************/

Application is not showing any error but command.out file is not generating. Once I compiled my code using "All platform" in project properties. and it worked but now with the same settings it is not working. my machine is 64bit and I usually compile my code on Visual studio 2008 32 bit platform.

Please let me know if anyone have idea about this.

Thanks in advance,
