View 1 RepliesI have used timers in .Net for a long time now an never had this problem.Start timer to fire every 10 seconds that reads an object and updates the UI using a delegate.This works great until the form is minimized several times, then the timer thread seems to vanish.Anyone come across this before?
Obviously I can roll my own using a thread directly and sleeping it, however this seems like reinventing the wheel when a threading timer class exists already.

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 2 RepliesI have a Textbox on my application that recieves data from another application via a sendmessage call from the other app.
I can see the data being entered in the textbox but the TextChanged event never fires when the text changes. I need to process the data that is sent but since the event does not fire I'm kinda stuck..
I am trying to implement an update panel on my web page. when I add this, everything works fine:
<script runat="server">

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">
<Columns>
<asp:TemplateField>

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";
