just now I was trying to capture the F1 key on the form, but only managed when the form is selected, and I need to detect it in any form control. I used this code:
Select Case e.KeyCode
Case Keys.F1
MsgBox("Right")
e.Handled = True
End Select
ok so i have a PANEL control under a WINDOWS MEDIA PLAYER control. Both are same size.
The panel has a click event which shows a message saying "HI"
when the panel is behind the wmp control the message is not shown when i click on it.
so the question is is there a way round it, cos currently it only works if the panel is on top of the wmp control
I am trying to get the event firing when document is ready.

I do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

View 5 RepliesWhat is happening now: i click the area in the taskbar which "belongs" to my form, while it is being shown, the form remains "shown"
what i hope to get done: if the form is "shown" and i click the taskbar of my form, i want it hidden
could we detect click event of the form's area in the taskbar?
Ok before I get flamed hear me out. I have a form with panels containing tablelayoutpanels containing various amounts of controls that alternate visibility. On the form in its entirety I am looking at roughly 3200 controls most of which are radio buttons.
Now that being said, I am trying to figure out a way to capture what control (mainly radiobutton) is being clicked on through the forms events. So far my attempts have failed with mousedown, mouseclick, etc. Yes I know I can use the "handles radiobutton1.Clicked" event directly. However with that many radiobuttons....I know that there has to be a better way to do this. An API, windows hook, something. So far my efforts to find an alternative method have failed.
if any one knows of a way to determine if a control is currently in the viewable area of the parent form. In example...if I have a form where all controls are visible when the form is maximized, how would I go about determining which controls are no longer visible to the user after they change the window state or form size. To be clear I am not talking about the visible property of a control but rather if the control is actually on screen for the user to see when they do something like resize the main form for instance.
View 5 RepliesI have created a User Control and would like to be able to detect when the user clicks on the Form.I have seen this question which is related but the suggestion to use the the Leave event doesn't always do what I want because the focus doesn't necessarily change when the user clicks the Form (my control could be the only control on the Form in which case focus stays with my control).I want to be able to do something like this from within the User Control:[code]

I have created simple windows form control with some events.
This form has button which opens Form with some settings.
Now, I need to raise the events inside the control when I click some buttons within the settings form ..
i'm trying to trigger control events from outside the form that the control is placed. The idea is test of that control.
How this can be done.
For example I'm trying this

I'm working a program where I need to capture the mouse down even at the form level. I need this to happen regardless of where the mouse is clicked. The standard mouse event (see below) works fine if the mouse isn't over a control. However, when the mouse is over a control, the control gets the event before the form. I can generate an event to capture the mouse event for every control and the pass the event on, but that is ugly and requires way to much maintenance. Isn't there a way to tell vb that all mouse events go to the form?

A few weeks ago I wrote a wrapper for the ServiceController control to enhance and streamline the base ServiceController. One of the changes I made was to add a monitoring component using the System.Threading.Timer object. On any change of status, an event is raised to the parent class. The actual monitoring works fine, but when the event is handled in the main form, my program abruptly ends - no exceptions, no warning, it just quits. [code]...

Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.
I have a user control that I have added a listbox to. I have added this control to a form and would like to use its click event.
Private Sub mycontrol1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mycontrol1.Click
When I click on the control on the form it does nothing none of the code for this event gets triggered. If I click on the listbox inside the user control that .click event inside the control does trigger. How can I make the click event for the user control trigger when the control is clicked?
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?

View 5 RepliesThe following zipped up Visual Studio Solution on Skydrive is immediately buildable and runnable; a usercontrol on a Form. Problem? If you click on any of the Edit Buttons and move the Horizontal Scroll, the values as they change in the Label_Values are off by one when you release the slider button. I think this is a timing problem between the Paint handler and the Horizontal Scroll event handler at the very bottom of the User Control code. Sorry I didn't eliminate

View 2 RepliesI have roughly 20 text boxes on my form,When you press tab, it naturally selects all text in the box (highlighted in blue), so you can press any key, and it replaces it with that,That result is what I want, unfortunately, if you click into the text box, and tab back to it, it no longer selects all the text.I'm wondering how I can detect the tab event properly,I've tried adding a 'KeyDown' event to each text box, and then selecting the text, but the sub never runs, also tried detecting the tab event in my Main Form, thinking that perhaps the parent handles it and will receive that event, but.. No.I've thought of using an event like 'Activated' however, it will also run when the mouse is clicked.

I have added lost focus events to all textboxes so as to validate user input. When I click on cancel button, i want to detect cancel button click, but textbox lost focus is fired first so I get error message for textbox before my code moves to cancel button click handler. Is there any way to detect button click before lost focus event?
