Hi Plamen,

Thanks for your patience.
Ok, I see what you mean now for the declaration.

private void Form1_Load(object sender, System.EventArgs e)
{
	ADODB.ConnectionClass adocnnTest;
	try
	{
		// Do this:
                  adocnnTest = new ADODB.ConnectionClass();

		// Do NOT do this:
                  // ADODB.ConnectionClass adocnnTest = new ADODB.ConnectionClass();
	}
	catch
	{
		MessageBox.Show("Error", "Error: Missing Required Files", MessageBoxButtons.OK, MessageBoxIcon.Stop);

		return;
	}

	adocnnTest.ConnectionString = "bla-bla";  //<- Use of unassigned local variable 'adocnnTest'

}

Using the above example, do you get
Use of unassigned local variable 'adocnnTest'
at the point of setting the ConnectionString?
