How can I get the SelectionStart value for a control in the Form_KeyPress event?
Form1.KeyPreview = True
Form1.KeyPress
Dim X as Integer = ActiveControl.Selection {gives error}
Dim X as Integer = TextBox1.SelectionStart {this works OK BUT will only work for one control because it is hardwired to TextBox1}
I'm trying to use the SelectionStart property in a textbox (VS 2003, SP1). The build doesn't flag use of the property, and the app runs, but the SelectionStart code just doesn't work: Textbox1.SelectionStart = 20000 (just want cursor to go to the end of box, and there are never that many characters in box)
The object browser reveals that the SelectionStart property is not included in the System.Windows.Forms textbox control I'm using. SelectionLength is there, but not SelectionStart. The control is inherited from TextBoxBase, which does contain the property -- it just isn't translated into theTextBox control. MultiLine is set to true.

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...
Code:
Imports System
Imports System.Windows.Forms
Public Class form1

With my form I have a datagridview, and from the datatable the data's are loading to datagridview.But the problem is when it's getting focus, it's selecting the whole contents of the cell of column(0) & Row(0).But I want to select like textbox
TextBox12.SelectionStart = 0
TextBox12.SelectionLength = 0
So the prompt will be in the starting position of cell...Is it possible for datagridview cells?My codings for datagridview

View 2 RepliesI have a menu item in a program that I'm working on called "mnuFileSave" The Click event goes through several "housekeeping" functions and calls the correct "Save" function.
Another menu item performs a function and depending on the results may want to call the "mnuFileSave".
I have tried RaiseEvents mnuFileSave.Click and get the error "mnuFileSave' is not an event of 'The_Entertainment_Collection.frmCollectionBook'
I have tried Call mnuFileSave.Click an get the error "Public Event Click(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event."
i already finish this module but while doing 2nd module i notice that my 1st module doesnt work anymore, then i checked my code, i double click the control at design time and thats it instead it brings me to my actual code of that control, it brings me to another event, like this, this is where my original codes are placed:
Code: Private Sub lblSupplier_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub then, after the poblem occurs, the control created another event like this:
Code:Private Sub lblSupplier_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub notice the difference, they are the same click event but the other one has an "_1" at the end of click.
