C# Credential Manager
Prompt for user credentials using CREDUI.
I have done this so many times in the past and then I always struggle because all the code samples are in VB.NET and I code in C#, so I thought, just do it and put it on your blog so others can use it and I can get to it easily in the future.
With the CredentialManager you can specify the target name, the parent form, banner bitmap and I am using a delegate to execute the success story.
1) Change to a different blog provider, then;
2) Save the draft
3) Change to HTML view, then back to the view you were on.
Your files will be ready to upload then.
