I have a combo box that lists Customers:
Customers
ABC001
ABC002
ABC003
If I select ABC003 from the Combo box drop down it replaces the first line of Combo box text with that text. i:e ABC001 is now ABC003.
So if a user selects a customer and then changes their mind to say ABC001. ABC001 is no longer available.

View 5 RepliesI'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.

I have two comboBoxes: cB1 and cB2. Depending on the values I have selected in both comboBoxes, another value puts in a third comboBox called cB3. But if the combination of selected values between cb1 and cb2 don`t give any value in the third combo, first of all It has to appear a MsgBox advicing to the user of this situation, and secondly, I want that the execution thread of the application could be pause /stopped for the user could choose any value selected manually of cB3.
This last action is the problem because I am not able to stop/pause the execution until the user can select the value, and the code after this point is executed and gives me a Nullreference error.
