I need to retrive a part of the value present in combobox.Suppose the ComboBox stores the Time values in it.
eg.
00:00
00:30
01:00
01:30
Then how can I retrive only the hours value or the first two values separately from the Combo Box.Is there any function like Substring to break the values....
So I have some vb.net code, and I have a nested For loop inside a For loop, and then I have EXIT FOR statement, will it break out of one loop, or the whole chain?

-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.

View 3 RepliesI have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?

I created a small vb.net console app in visual studio 2008 trying to learn .net but my results show differently when I break in the code and press F11 to step through. If I do it this way, the results I expect to get show but if I don't break into the code the results aren't what I'm expecting.
Basically everytime I click a button i want to write four numbers that are random. If I break into the code, these show random numbers i.e. 1 3 4 3 but if i don't break into the code. my numbers are all the same i.e.1 1 1 1. Here is my code, like I said I'm still learning so the logic is probably not correct.

View 1 RepliesI've got this variable iCurrentScreen. I've got a breakpoint on the line of code that writes something to the event log and I've made that breakpoint conditional so it only breaks when iCurrentScreen =1. However, whatever's setting it back to 1 I don't seem to be able to track down. Before I go putting breakpoints on every line of code that changes the value of iCurrentScreen . is there a way to tell the system to let me know when iCurrentScreen becomes 1 no matter where it happens?
