View 6 RepliesIn a small vb.net application is use the shortcut's F1 and F3 to start/stop a timer countdown.In fact not the Keys itself are pressed, but i have to buzzers connected via USB who are simulating F1 + F3 when pressed.Precise the application runs on a karting track. When a driver enters the pit he/she will press the USB-Buzzer to start the countdown, pressing the 2nd buzzer when leaving the pit.Everything is going well, with one exception.After a longer period without activity the application will not react on first hit on the USB-Buzzer so they have to double press it to start the timer.
i already activate the winform with a timer in background (also center it on screen/center the mouse/making them topmost) but it seems the application falls into sleep and the first hit on the buzzer is the wakeup call for the form an the 2nd is forstarting the countdown.How to make sure that the application will start the timer on first hit.
I have a multi-line textBox disabled through vb.net :
myTxtA.enabled= false
The html it outputs :
<textarea name="myTxtA" rows="10" id="myTxtA" disabled="disabled" style="width:99%;">
...
</textarea>
That's the source code I get through the browser but the textArea is still editable in the browser. There is no javascript modifying myTxtA, and the only other reference to myTxtA in my codeFile is the following :
If somethingNotHappeningHere Then
myTxtA.ReadOnly = True
End If
I can't see why my textarea is still editable. Can the class of the div containing the textArea modify its behaviour ?
PS: I am not concerned about if the data is sent or not. I'm just looking for the textArea to be uneditable.
Edit: Same problem on IE7 and Firefox 3.5
Edit 2: When I copy all the html source from my browser into a new html file the textarea is properly disabled...
What is command to make window active? I want one of my windows to be on top of all other windows that I have opened so I can work with it
View 9 RepliesI'm using Visual Basic 2010 Express.I have a form that can be minimized.There's also a tray icon.I've coded it so that if you double-click on the tray icon, the form's FormWindowState becomes set to Normal; this restores the form to where was before it became minimized, but the form does not become the active window on my desktop.
How can I make the form become the active most foreground window? I've tried various functions that I can think of but no luck yet. Tried searching with various queries to try and find the right wording but no luck.I'm new to Visual Basic - only started a couple hours ago.Probably something simple but I can't seem to find the correct function or anything.I have the form/window open, and then I overlap said form with a window of another application. When I double-click my app's tray icon, I want my window to become the active window, bringing it to the front, but can't figure out how

I want to make an application that allows the manager of the company whether the employees are truly active: screenshot and a "timer" to measure the time of the activity of the employee Can be controlled using the mouse or keyboard while the application is not active, but in execution.Is it possible in vb.net to know if the user of the machine is using the mouse or keyboard? My idea is to set a "Timer" which triggers automatically after the connection of the employee and every 10 seconds the application checks whether the mouse position has changed or a letter is entered on the keyboard except the"Timer" Will Be stopped until have a new mouse position or activity on the keyboard. But the problem is: is the application able to know the position of the mouse or to capture all keyboard input even if the application n 'is not active(not in the foreground)?

View 2 RepliesI have a standard Visual Studio 2008 VB.Net WinForm application, running on Vista Business. One of the forms has a timer that passes Me.Handle to FlashWindowEx. This works as intended as long as none of the windows that belong to this application are the Foreground window. If this program is running and another application's window is the Foreground window, then it flashes as intended. If, however, any of this application's windows are the Foreground window, then it doesn't flash.
