I'm just a beginner at VB.NET...I want to be able to insert a combobox control onto my form through code but I'm not sure how. Google doesn't seem to answer.
Something along the lines of (I have no idea)
Me.AddControl("Combobox")
I would obviously then need to set the properties to setup the position/size etc.
I want to fill up a combo box with all the keys from System.Windows.Forms.Keys. My question is how can I do this?
View 6 RepliesI have a custom collection which is derived from a base class implementing IEnumerable and IEnumerator, this collection is populated with custom objects.I'm trying to set the datasource on a ComboBox on a WinForm to use the above collection - but when the code is run the ComboBox is always empty.
The code I was using was this:
Private Sub ViewSources_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
' declaration
Dim sourceCollection As SourceCollection
Dim source As Source
[code]....
When my form loads, before the ComboBox has been populated and selected this Event (SelectedIndexChanged) gets triggered. How can I prevent the code insides this Event from Executing before form has completely loaded? I tried testing for .SelectedIndex but it returns 0.
View 3 RepliesI've got a basic VB.net 2.0 application together in VisualStudio 2005. Within a form, I've tied [enter] in several text boxes to a button. What I'd like to do is "press" the button from getField_KeyDown() to give the user a visual indication of what's happening.With the code below, the button click work is done but the button's look doesn't change and the user is left without feedback.
Private Sub getField_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtGetKey.KeyDown
If e.KeyCode = Keys.Enter Then
e.Handled = True
Call btnGet.PerformClick()
End If
End Sub
How can I make the button looked pressed while the btnGet.PerformClick() work is being done?

i have one project (let's call it project1) that is going to add properties to another project's class. The thing is I wanted to make it automatically. So in my project there are two lines of code which I want to add at the bottom of the class.vb or class.cs in a project called project2. Is it possible? If so, how?It is a data access builder software which after adding some new columns to our database we use it to generate its properties and its parameter to be added in BLL. Since we do it often (changing our database structure) I did not wanted to copy data from data access builder software and add it to project2 manually.
