Dequeue Data In Paint Event Of A UserControl To Show Continuously Moving Waveform?

May 11, 2011

Given this illustration and basic code, how do I dequeue and draw the data that has been inserted into the User Control's Preperty queue? The graph/chart will need to show anywhere from 1 to 120 seconds of data, with each second representing electrical waveform data that arrives each second with a variable amount of sample data..The timer interval will have to vary with the amount of incoming data so that it shows a continuously moving waveform from right to left and the rate of drawing keeps up with the amount of data arriving. (so the queue doesn't get backed up)

Can't Seem To Get Form.GotFocus Event To Fire

Oct 21, 2009

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]

Asp.net - OnClick Event Will Not Fire In Firefox Or Chrome Only In IE

Apr 30, 2012

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";

[code]....
