Not sure exactly what I need to do to make this work, so my description may be lacking at first.Essentially I am writing a program launcher that recreates itself each time on load. It pulls the data regarding the tabs and buttons from an SQLite database and builds itself dynamically at run time. I get my problem when I pass the tab name through to the function that creates the buttons. I need the name to pull the right set of buttons from the database and I then tried to use the name to place the buttons on the right tab when I create them, but the debugger calls it a null reference because it doesn't point correctly to the tabpage that I'm trying to make it point to (at least that is what I'm guessing). Any ideas on how to make this work right?

I need to work with a previously stored listbox. Example: You save a file and it comes in the listbox, I can click it and I see it in all my textboxes. And if I restart the program it's still in the list. The files can be anywhere on the computer, that's why I need this method. The name that need to be in the listbox is the name of the save file.
add a custom field and/or attributes in active directory (whichever their called) for a user. For instance, im wanting to add a field for employee id but can I also get this field to show up in active directory users and computers to see if its working correctly? Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. - "Sherlock holmes" "speak softly and carry a big stick" - theodore roosevelt.

I am writing a simple program that serves a similar purpose as the character map, but just for the Spanish letters with accents (������ & ������). Character map doesn't work for me because I have to highlight the letter I want to insert and then copy it and then paste it into whatever window I'm working with.What I want to make is a program that has buttons for each of those letters, and when I push the button for a particular letter, it inserts the character into whatever window was active before I pressed the button. I also want whatever window that was active before I pressed the button (the window I inserted the character into) to become active again so I can resume typing right after I press the button.I have programmed in VBA before, but this will be my first VB project. I have tried searching how to do it, to no avail. Where do I begin?

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?
The program I am working on uses arrays and a text file. In one section of the program it's suppose to display the most active year for storms between the years 1990-2008. The year that has the most active storms is 2005, but I don't know how to write it in the code so that it displays. Attached is the text file.
So far I have a For Next loop that counts the arrays.
