Asp.net - Detect F5 Being Pressed And Refresh?
May 25, 2009
I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.

I have wasted lot of time in searching and finding the simplest way to detect a page refresh and when the user press F5 button on his browser.I have seen most of the samples provided on net but none of them could satisfy my needs.I will explain in a simple step way to understand my issue:
I am trying to use sessions and loading some images and storing them to folder.Next I have a button to process some operations on images.(Here I have a postback where I am trying to detect postback and savng them to the same folder.)Now here comes my issue now whenever user tried to refresh his page manually or by clicking F5 buton on his browser I need to load all the images again from the folder.Here is my code:
If Page.IsPostBack Then
//Here I am checking if the session is there or not.If it is already there I am adding images.
Else
//
Here I am creating a new session and adding images.

im working on a little app for my self, to make my life a little more convenient. I have some media keys on my laptop, and I would like to use them with itunes while it is minimized. I found a app that did it for me a long time ago, but cant seem to find it now. But I would like to try my hand at my own, and I've managed to do so, but, my app has to be in focus for it to work. is there any way to still detect when these media keys are pressed while my app is out of focus?

How would I check if a key is currently being pressed?
Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.

This may sound like a dumb question but I need to know. I know you can tell which keys are pressed on the keyboard but I like to know if I can do something.Ok, heres what I am trying to do. A user is in another program that is max on the screen. He has to press Print Screen to take a screenshot, but he got to min the screen he is in to paste the screenshot into paint. This causes slow loads on maxing that screen and sometimes crashs of the program. I already got the code done to check when the program is running and to capture the screenshot and save it. What I to do now is, find out while in the other program with my program running in the background, if the user has pushed the Print Screen button.

Im doing a small project in visual basic which involves lighting up leds through the parallel port and turning them on and of. each led is controlled by a checkbox on my form and they only come on when the checkbox is checked.
what code do i need to use to have the checkbox checked when a key is pressed but when the key is released the checkbox is unchecked i have already tried keydown which will check the box when a key is pressed but will not uncheck it when the key is released
If e.KeyValue = Keys.A Then
CheckPin1.CheckState = CheckState.Checked
ElseIf e.KeyValue <> Keys.A Then
CheckPin1.CheckState = CheckState.Unchecked
End If
