[code]I just cannot figure out why VB6 works but .net doesn't and fails only on the target machine not the development machine.

I was unable to find anything in my searches for XML or INI on the forum so i apologize now if this has already been asked and answered before.
I have been searching Google for days now, trying to find information on Reading and Writing XML files. I wish to use them to replace INI files in my programs.
I have been using VB6 for years now, but was able to get a copy of VB.NET 2003 really cheap and so i am trying to learn how to do the things i did in VB6 in VB.NET 2003.
I was able to find code to write to an INI file, but was not able to successfully read from an INI file with any of the code i found.
I have been able to find code to write an XML file, but when i try to update it, it replaces the old file with a new one, and the old settings are missing, instead of the new settings added to it.
i can at least start migrating to VB.NET 2003, or if you read XML and update XML data, i can switch now. Here is the code i have for writing XML.[code...]

I have an application which reads and writes to the registry. If the programs starts, it looks if the registry keys exists. If not it create the keys. All this is working fine on a Windows XP machine.
Now we moved to Windows 7 and it is not possible to write to the keys. First I need to go to the registry and add permissions. Then it works !
Is it possible to change the permissions in the .Net code and make it able to write to the registry without changing permissions through regedit ?

I am working on a program with multiple collections related to one another for a school project. Each collection needs to have its own defined properties and have the objects written (1 per line) to a text file.
I have all of that working.
When reading the comma-separated line from the file, I want to place one of the properties of the object in a listbox (so that all the objects' names will show up in the listbox). I think I have this part figured out...
My problem is that when you click on the name in the listbox, I would like multiple text boxes to be populated with the appropriate, corresponding properties of the particular object in the collection...is there a way for this to be done?

I'm trying to write out a date like this 09-16-2008 so I can put the date in the name of a directory. Here is my code:
Code:
Dim aDate As Date
aDate = Date.Today
aDate.ToString("MM dd yyyy")

I can't seem to get the leading 0 in front of the month if it's a single digit. I can't get rid of the time, and I can't get the dashes.

The setup is running in 32 bit mode and the installer class is made with Visual Basic installer class.
Now the problem is, how to read SQL Server 2008 64 bit registry settings in Windows Server 2008 R2 64bit machine.
E.g. installed instances and the data paths for every instances.
I need to check the SQL Server instance name and read from registry the database location path for that instance.
By default it reads the 32 bit registry so it does not found the settings at all.
Example code that can be set in visual basic installer class would we nice.

I have an INI file built like this:
[registration]
key=<key goes here>
passkey=<passkey here>
and using a registration system (found in codebank here), I'd validate it like that. I just need to know how to read and write from it. All the ones on google are too vague, or focus on the wrong part.

I am trying to use a .dll in .Net that was written in C++ and was previously used in a VB6 application. I get the error mentioned above. I see lots of posts referring to how VB6's long data type is different in .Net but these fuctions use only integers and strings. Can anyone tell me what is wrong with this?

I am working on an application that starts a few threads every second. The threads don't do much, and everything seemed fine. I monitor the number of threads running, and I have never seen it higher than 4.
Last night I started the app and this morning I had this.
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
The threads can make changes to two List(of Strings) and I had SyncLock's surrounding the code that did that. It has been running for several hours again and all seems well.
My question is that I found a place in the UI thread that was copying the list without the lock. Could that have caused the error?
how to debug something that isn't going to fail conveniently?
