SetEnvironmentVariable in Debug and Release configuration

Question

Hello folks,

I was trying to set some environment variable for a process I create.
(The variables are my own, not system).

I use SetEnvironmentVaraible() from C# code.
In Debug configuration this works fine, but in Release configuration the action fails.
The return value is TRUE, and no Exception is thrown.

 This is the relevant code:

bool bStat = false;

StreamWriter swError = new StreamWriter("a.txt");

try

{

// Get the write permission to set the environment variable.

EnvironmentPermission environmentPermission =

new EnvironmentPermission(EnvironmentPermissionAccess.Write,

i_sVariableName);

environmentPermission.Demand();

// Set the Environment Variable and return the result.

bStat = SetEnvironmentVariable(i_sVariableName,

i_sVariableValue);

// Log into file.

swError.WriteLine("The result of setting environment variable " +

i_sVariableName + " is :" + bStat.ToString());

}

catch (Exception e)

{

// Write the exception into file.

swError.WriteLine("An exception has occured while trying to set " +

"environment variable " + i_sVariableName + ": " + e.Message);

swError.Flush();

}

finally

{

// Close the exception log file stream.

swError.Close();

}

return bStat;

Any ideas ?!

And how did you determine it failed?

By using Process Explorer.
Also, I have a C++ DLL that calls to getenv() upon its initialization and fails.
