I have worked through all of the steps in this Try It Out. I filled in the values on the form as specified (putting in my own values for Server, Login and Password). When I click Create, I get an error message in the Encrypt method saying "Specified key is not a valid size for this algorithm."

I have gone back to make sure that I typed in the values correctly in defining bytKey() and bytIV() in the btnCreate_Click sub and they are equal.

I am running Windows Vista (sorry) with .Net framework 2.0.50727. Any help would be greatly appreciated.

Eric,

If you put in your own values for the bytKey() and bytIV() byte arrays you need to verify the length of the characters you are using. ASCII character codes on chart 1 (http://msdn.microsoft.com/en-us/library/60ecse8t(VS.80).aspx) will take up one byte in the array. ASCII character codes on chart 2 (http://msdn.microsoft.com/en-us/library/9hxt0028(VS.80).aspx) will take up two bytes in the array because they are considered unicode characters.

I hope this helps.

Thank you, Thearon. I found what was causing the error: the key wasn't getting set properly in the WDACrypto class. The error has been fixed and I was able to create the registry keys.

I appreciate your help and the books (I read Beginning VB 2005 before this); I've learned quite a bit in the past few months.
