Assign Index On Combobox/Listbox?
Jun 15, 2009
Trying to learn VB 2005. So my questions might tend to use the logic from VBA/VB6.
So, my question is, is it possible to assign indexes on the listbox/combobox? What I have is an ID and a Description from a table and would like to display it on listbox/combobox to allow user to choose from by looking for required description. When selected the ID will be used to search for other information related to this ID.
I manage to display the description but how to assign the IDs?

Is it possible to (or how can I) assign values to a class property array like this:
MyImgClass.RGB = (255,255,255)
I'm not sure how to build my Public Property setter to allow this, if it's possible at all.

I have an application in VB.Net that displays the results of a math operation to a listbox. For example I have the 12345 + 12345 = 24690. What I'm trying to do is to have the first 2 numbers (12345 and 12345) copied to 2 different textboxes when listbox item is selected. Here's the code I have so far:
'Make sure that we have a selected item before continuing
If listBox1.SelectedIndex = -1 Then
Return
[Code]....
During runtime it only works with index 1 when it gets selected. I have 10 records being displayed (0 to 9). None of other indexes are being shown at the textboxes.

I'm trying to assign a datasource to a ComboBox control during runtime. When I do so, I get the attached message. Here is my
cmbAddressDesc.DataSource = dbDataSet4.tblAddressCodes.addrDescColumn
dbDataSet4 is a typed dataset. I want to learn how to use an Interface. The error message is suggesting using an IList. How would I do this. I'm having trouble finding good documentation on this.

It appears that I cannot assign the selectedindex for a databound listbox if it has no parent, but I can do so if I have populated the list "manually" from the same datatable. In my code example, the "if" line toggles between loading a list via data binding and loading a list "manually" (both use the same data table). In each case I attempt to set the selected index afterwards. With manual loading, the selected index is set; with data binding, an error is thrown (which can be avoided by assigning the listbox a parent, but the "manual" equivalent doesn't need this). Is this a bug?

So I am able to get the comboBox populated with the proper list of "clientLocations".
However they all have a valueMember of 0; thus the issue at hand is properly assigning the value of the comboBox items to the database column (which is returned in the dataset) rather than just the name.
Private Sub updateClientLocationComboBox()
'clear list
comboBox_clientLocations_deviceList.Items.Clear()

I have been looking over some old vb 6 code and I noticed that there was a way to set the index of a listbox to a new value. For instance, if you wanted to populate a listbox with items from a database you could assign an id value from the table as the index value so that it is easier to relate back to the database. Does anyone know if and how to do this in vb.net?

I have a comobox and a timer.
im trying to make it so the index of the combobox is "for example"
1
2
3
4
5
each number will change the timer
1 = 1000
2 = 2000
3 = 3000
and then the code will be something like If comobox1.text = "1" then timer1.interval = 1000
end if

I have a combo boxthat holds a list of values that are a custom object and when a value is selected a few text boxes are loaded with data. I use the SelectedIndexChanged Event. Works wonderfully.I noticed that this even is also called when a user clicks the 'x' to close the form. I just wanted to understand the logic behind that. I get that the technically index is changing since the cbobox value is being set to nothing, but to me that just seems a little inefficient.
