OSDComputerName variable and .Net

[RaymondA]

Hi,

 

I am investigating/considering to make an setup-screen in the OSD deployment.

I am using VS.net C#.

 

However, I am having major problems.

 

The idea I have is to give the user the option to change the installation values, if he clicks inside the app (10 seconds delay).

The application should displays:

Computername, Bitlocker, default regional settings, program packages, etc.

If he wants to change the computername, the program will help the user to make a name that’s unique and within Company Policy.

 

 

 

However, I need to evaluate the existing %OSDComputerName% variable.

 

I want to check if it is a SCCM generated name (“MININT-*“), if so the application should always stop and make the user create a computer name.

This section of the code is as follows:

            
TSEnvClass TSENVVAR = new TSEnvClass();
string sComputerName = "";           
try           
{              
compName = TSENVVAR["OSDComputerName"];             
this.textBoxComputername.Text = sComputerName;              
Log("OSDComputerName = " + sComputerName);          
}          
catch (Exception exc)            
{               
Logg(string.Format("ERROR OSDComputerName: {0}", exc));     
}

I also reads other settings, set by the Task Sequence prior to this step.

 

My problem is as follows:

 

I can read all variables, but the "default variables" are empty (zero length string).

 

I obviously am missing out on something. When, in the task sequence, is the default variables set and ready to use?

 

Or, am I doing something fundamentally wrong?

 

 

Second question... Is there some exception handling I should know about?

It is correct that OSDComputerName is empty when it is not used. The name is actually stored in the read-only variable _SMSTSMachineName and that value will be overwritten with the value of OSDComputerName (when used). See also: http://technet.microsoft.com/en-us/library/bb632442.aspx
