VS 2008 Why Doesn't The ComboBox Have A Selected Integer Property
Nov 26, 2009
Why can't you set the selected integer for the items in the combobox in the properties window instead of adding code in the form load event? I don't like to have to do things that way, I feel like it is less efficient. Should I just deal with their being no value property for combo boxes or is there a way to do it easier?

I need to develop a function called SetComboBox that accepts the category(ies) in the ComboBox as a string and returns an integer indicating the index position of the category in the ComboBox. The function is supposed to set the category in the ComboBox Selected Index property to match the string category stored in a database for an inventory item.

I have a form created in VB.net. It is used to get some information form a user. The form is not bound to any data source.A combobox on this form is used to enter a cost. I want the value entered by the user to be displayed using currency format. I have used the Format String Dialog that opens from the ellipses button on the FormatString property of the combobox and selected Currency. This put C2 into the FormatString property.When I run my application, this format is not applied to the value entered into the combobox at the time the number is entered or when I leave the combobox.

My question is, the SelectedItem property of the Combobox is supposed to return a integer value, is it not? Because I am getting back integers, sometimes, then the next time through I get back a String. Has anyone else had a problem like this with the Combobox?

I have a weird question and I honestly hope you understand what is happening here: I design my form (using VB.NET) and put on it a few textboxes, comboboxes and a listview. After the design, I want to adjust the TabIndexes for each control on the form. On the right-hand side of the interface is the property box.
I then select the 'TabIndex' property item and enter a number key (for instance 0) for that selected item. I then select the next textbox control and enter the next number (for instance 1) WITHOUT re-selecting the 'TabIndex' property item. As soon as I select the combobox or listview control, the currently selected property item jumps to 'Items' or 'Collections' and does NOT remain on the 'TabIndex' property item. Why is this happening? Everything worked fine and all of a sudden this starts happening. Should I reset the editor settings or how can I resolve this matter?

I have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.

In my VB.net solution I have a form in which I have to choose a beginstation and an endstation. I have to select both from comboboxes. Now what I want is that when I choose a beginstation, the chosen station will be gone in the combobox of the endstation so that I can't pick the same endstation as the beginstation.Is there a way to do this? I've tried a lot with SQL and LINQ queries but it didn't work out :(

I need to set property values with WMI but it doesn't work. For example:
obj = New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
For Each objMgmt In obj.Get
objMgmt("description") = value
Next
That is supposed to set the computer description but it has no effects at all (and doesn't produce any exceptions). I can successfully retrieve value but I can't set it. The "description" property is supposed to be read and write, according to MS.

I am using code similar to this to populate a combobox with items from a database. The display works fine, but when I try to get the combobox.SelectedValue it is returning a DataRowView, where I need an integer. Obviously this is becuase I haven't casted the value to an integer, but the function, CInt(cboPosition.SelectedValue) is throwing an InvalidCastException. Is there any way that I can get the ValueMember's type to be an Integer?

I've been having problems with a really basic search routine that I have used successfully before but now for some reason does not. I have a text file that looks like this: Spindly Killer Fish, fish, spindly, aggressive, dangerous, grey, Sect.B Tank.1, 20 It is then loaded into a two dimensional array with comma separation. This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]

I am using VS2008, vb.net, Windows forms project.I have a combo box control on a tab control.The selected value of the combo box is bound to a binding source.The data source of the binding source is a typed dataset.I set the datasource of the binding source when a record is chosen in a data grid control.Since the combo box is bound to the binding source, this should set the selected value of the combo box, and fire the initial SelectedIndexChanged event.Therefore, I remove the SelectedIndexChanged event handler for the combo box before I set the datasource of the binding source, and add the handler again after the datasource is set.
