Selected A Value Of A ComboBox By Second Time?
Mar 30, 2010I 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.
