Error running app but not while debugging!

[Don Gollahon]

Help please! .NET 2.0.

I have a hashtable defined:

public static Hashtable Params;

It currently is in a shared class in my app. I have moved it from the
main form to the shared class but get the same results no matter what.

When I run the app within VS it works fine! But when I run it outside
of VS I get "object reference is not set to an instance of an object"
and it is the Params.

Any ideas how this could be?

Could you give more explanation about it.

For instance, how do you intialize the Params member.
At what line of code do you get the error (you can get it by looking at the
stack trace of the error object.

where the error occurred.

I inserted a test line to make sure this is where the problem was and
it is. The following is in the Main() method:

Main.GetINISettings();
try
{
string vstr = SharedClass.Params["LOGSERVER"].ToString();
}
catch (Exception E1)
{
MessageBox.Show("Main Params: " + E1.Message);
throw (new Exception(E1.Message));
}


And here is the GetINISettings method:

private void GetINISettings()
{
if (System.IO.File.Exists(IniName))
{
FileStream vini = new FileStream(IniName, FileMode.Open);
StreamReader vsr = new StreamReader(vini);
String[] elements;
try
{
while (!vsr.EndOfStream)
{
string vstr = vsr.ReadLine();
elements = vstr.Split('=');
SharedClass.Params.Add(elements[0], elements[1]);
}
}
catch (Exception Ex)
{
vsr.Close();
vini.Close();
Environment.ExitCode = 9000;
throw (new Exception("Config file not found or invalid: " +
Ex.Message));
//MessageBox.Show("Config file not found or invalid. " +
Ex.Message, "Error", MessageBoxButtons.OK);
return;
};
if (vsr != null)
vsr.Close();
if (vini != null)
vini.Close();
}
}

I forgot to include this in the sample I sent. It is before the other
code in Main():

SharedClass.Params = new Hashtable();

Uhhh, nevermind.

I forgot to move the ini file to the working directory.

Good grief!

Hi,

Take a look at the ini file, must probably you are using a different version
when you are debugging

Yep. Actually, blush, I forgot to copy it to the working directory and
not just the development area.
