How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True
Public Shadows Property Enabled As Boolean

VS 2008 WinForms Label Control Handle Focus?
Jan 30, 2011There is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1
- treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.

Forms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?
Feb 16, 2011Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

.net - Winforms Textbox Focus With TabControl?
Aug 22, 2011VB.NET Windows Forms Project, VS2010.I have a tabcontrol with several tabpages and on each tabpage there is a textbox. I want the focus (and insertion point) to go to the end of the text in the textbox when the tab is selected. If I make a junky project with the following code in each tab, it works fine:
Private Sub TabPage1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabPage1.Enter
With TextBox1
.SelectionStart = .Text.Length
.Select()
End With
End Sub
However, the same code is not working in my actual project. I am having trouble debugging, because if I step through, the breakpoints and IDE mean the focus events don't fire in the same order.
Winforms - Difference Between Focus() And BringToFront()
Apr 12, 2012I'm developing an application in WinForms and I have 2 MDI children and I'd like to know the difference between Form.Focus and Form.BringToFront
I would like to know which one to use when clicking on a respective form's titlebar in order to have it pop up while I'm drag/dropping the form
If you are setting the child form mdiParent property after you are calling Form.Show then it messes up the focus of all the child forms so for me, drag/drop of MDI children inside an MDI parent won't focus the form upon Drag start, but only after MouseUp

Lost Focus Event, What Control Is Getting Focus?
Mar 21, 2012I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

View 2 RepliesFind Out What Windows Program Has Focus?
May 24, 2010I am using Visual Basic 2010 Express. I have a program that I need to have work in conjunction with the scanner software that our company uses. how to get my program to watch for when the space bar is hit and I have also figured out how to make sure that my program's "spacebar trigger" only works when the scanner software is running.
The problem is this: If for some reason the user decides to use some other program while the scanner software is running, my program still watches for any time the user hits the spacebar. As a result that triggers the "spacebar trigger." I only want that trigger to fire when the scanner software has focus. How do I do that?
Find / Replace Within A String For Winforms
Apr 26, 2012I have an issue with finding specific text within a string and then replacing it with " ", which is just a blank entry.[code]So now my issue is to search the ABCTEST text and delete text such as "Tier Market" from it. Then pass it to a new string perhaps ABCTEST_NEW..I know i might have to use a for loop to search out the keywords, but all the examples i have had a look at, are very broad.
View 1 RepliesWinforms - Find And Reference A Certain Form?
Jan 27, 2012I am currently making an application to aid me in testing another separate application (both are made in VB.NET). I want my tester app to be able to enter info in a form on my other application. Since I have familiarity with both applications, I know the name and everything about the form I want to do things with on my testee app. My problem, is that I need a way to use this information of the testee form to get a handle or something that I can actually reference that form with in code for my tester app.
How can I go about getting this form? my only experience with something similar was getting the handle of a main window of a process, but that was a bit easier by doing this:
Dim iTunesID as intptr
for each process as process in process.getprocesses
if proc.mainwindowtitle = "iTunes" then iTunesID = proc.MainwindowHandle
next
However even that I am not really happy with because it needs to iterate through every process. and even from this, I am not really sure how to reference my specific window, since it isn't the main window in this case. I have tried searching for how to do this, but my search is a bit too vague I think as I just don't know what methods are available to use to do this or assist in doing it.
my first thought was something similar to above but with something like "for each form as forms.form in 'forms.formsrunning'" kind of thing, but I don't even know a command to get forms running, and though I guess I could probably find one, I am hoping for a better solution than iterating through all processes/forms.

View 3 RepliesControl Focus / Control Select
Jun 1, 2010I have read this many times. Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms. What exactly is the difference?

C# - WinForms TrackBar Control In .Net?
Apr 7, 2010know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?
