I want to use an ini file (or similar, also looking at an xml file) for configuring the way macros run.
I found out how to read from an ini file and populate a textbox on a userform (this was surprisingly simple):
TextBox1.Text = System.PrivateProfileString("C:\path\my.ini", "GroupLabel", "DataLabel")
But updating an ini file with user preferences etc. still eludes me ...
