I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]

View 13 RepliesI have a form with over 100 textboxes that are set in multiple groupboxes and that number grows as I continue working. I am trying to get an event to fire if there is a keydown on any one of the textboxes. other than individually adding all 100 textboxes to the handler, is there a way for me to create a single event that handles all textbox.keydown events on the form?
I want to run something like the code below every time a textbox on my form changes. The code rules out text boxes within groupboxes that I don't want to fire.
If TypeName(SplitContainer1.ActiveControl) = "TextBox" and InStr(ctrl.Parent.Name, "GroupP1Payoffs") = 0 _
and InStr(ctrl.Parent.Name, "GroupP2Payoffs") = 0 and InStr(ctrl.Parent.Name, "GroupP1LoanDetails") = 0 Then

When a user clicks on the little red "x" a.k.a. the form close button on the form command bar, what even is activated besides FormClosed()
I know FormClosing() is called, but I cannot really stop the form from closing after my code is run. I want to be able to show a messagebox that asks if the user wants to exit the form or not. Obviously if they click no, I want the form to stay open, how would I do this?

View 2 RepliesI have a Textbox on my application that recieves data from another application via a sendmessage call from the other app.

I want it so when the "x" button is clicked a message box will appear saying "Are you sure you want to exit?" then if "yes" it closes and if "NO" it stays open. so my code is:
Dim a As Integer
a = MessageBox.Show("Are you sure you want to exit?", _
"Vice Versa 1.0", _
CODE:...................
This should work, no? When i debug my project clicking "no" still exits my program. Is this just because it's in debug mode or am i missing something here?
Also no warnings or errors. Is there a way i can make my game pause when the message box shows? I only have it working to if the users presses "p" on keyboard. But also want game paused when message box shows, without pressing "p"

This will cause the event to not occur. If i change the "<" from the string, all is well. why cant I have "<" in my strings? This is important because i wont allow me to put an xml string in the text box.
I am using a column with check box to be able to select my data row from a GridView. But The OnCheckChanged event won't fire. I have tried reading articles to make it work and copy code exactly and it just won't fire. I am using vb.net and asp.net
<asp:GridView ID="locationDetailGrid" runat="server">

in my application, I pull in http code from the server side. When this code is placed into the application - the event will happen when clicked in IE, but not in any other browser. Heres the part of the code that deals with the image that is clicked and the event.
<img canExpand="true" style="cursor:hand" id="img34635" src="../images/plus.gif" EntityID="346" EntityCat="35" onclick="LoadChild(this.EntityID, this.EntityCat, 0, this.lnEquip)">
LoadChild is a javascript function on the client side of the page. When the image is clicked in anything other than IE , nothing happens. Can anyone see why this is happening? It may be a formatting issue.
edit - here is the javascript function load child
function LoadChild(lnEntityID, lnEntityCat, FullExpand, EquipID) {
document.getElementById('dropTypes').disabled = false;
document.getElementById('dropTypes').style.background = "white";
