Firstly I want to state this doesn't affect the usability of my program. I made a GUI for an old cmd line program and when running the GUI's form will freeze up and be completely unresponsive. This is annoying since you can't move the form and if you open something over the form then move/close it you get the affect in the attached pic. Attached pic is the program running and the windows calculator being moved around over it.
Is there a way I can have the form stay responsive while the program is running? I don't need for any of the buttons, text boxes, etc to be editable while the program is running.

I have created a custom video player in C#. This player has two forms.
1. The Video Player window ( running in primary (UI) thread )
2. The content playing window (running in a secondary thread)
Everything goes fine for nearly 5-6 hours, then the main video player window freeze. So I cannot access any of the buttons (stop, pause ,exit) in the player. But the secondary thread keeps playing the files for even two days continuously (which is the max I tested).
Things I have checked :
1. There is no memory issue, since I dispose the objects I create after playing each file (few min videos). I have checked the process in task manager, where status is running and memory usage as same as it is started.
2. I have used Begin Invoke from secondary thread to update the current playing file in the list box on the main video player window (once the main window freeze, the update is not visible).
3. I have used a timer in the main video player window and tried refreshing form, calling Application.Do Event() for every few minutes, still it gets freeze up after 5-6 hours.
Why the UI window freeze up? Is my architecture for the player is wrong? (I need to do lots of processing in secondary thread for the images and videos to be played, but it is working fine).

My mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.
We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use
Channels(ChatIndex).Show()
The form opens but freezes.
I have also tried using
Channels(ChatIndex).ShowDialog()
Application.DoEvents()
Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)
What would be causing the form to freeze on .show(), Has anyone else had any similar issues?

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

I am having Socket server, and I have two forms. One is the main form for the server and the other one is a custom made messagebox. When a request comes to the server the main form has to invoke the second form (messagebox). When the main form is open for the first time everything works fine. But when I close the main form without closing the application and open it again and request comes to the server the custom made messagebox opens but it freezes and looks like this:

I've created a "Loading" borderless Form that's displayed when loading records etc. I'm using the following to keep the loading dialog centered within it's parent.Works great except fo when the form is minimised estore- The loading form appears instantly while the parent (Owner) maximises with the usual VistaWindows 7 animated maximise.
What would be the best method to prevent the loading form appearing before the main form?

Im trying make my application display my splash screen for 5secs before loading my main form. I have read lots of threads on this and they all seem to point to the following:Add the following code to the New() sub of the splashscreen.
My.Application.MinimumSplashScreenDisplayTime = 5000
I have also seen a suggestion to add the following code to the OnInitilalize event in the ApplicationsEvents file.
Me.MinimumSplashScreenDisplayTime = 5000
I've have tried both ways, and although it successfully makes my splashscreen wait 5 seconds before closing, it doesnt prevent the Main form from waiting for the splashscreen to close before loading. The mainform simply loads over the top of the splashscreen.This thread is exactly what im after but i cant seem to get mine to work.

I have application framework enabled. I have my startup form set to my main form, and i have set my splashscreen in the application tab of my project properties. Im using VS2008.I also noticed that when i clicked on the "View Application Events" button in the application tab of my project properties, the file was blank. I have seen that some other people have had problems with this. I just cut and paste the following code into my ApplicationEvents file. Potentially an issue??? Any reason why the code was not auto-generated to begin with?
Namespace My
' The following events are availble for MyApplication:
'
' Startup: Raised when the application starts, before the startup form is created.

I've been trying to use "System.Threading.Thread.Sleep(15)" as the delay code but if freeze the form. I used this "Location.Refresh()" where location is the name of the form, but it didn't give me what I need. This code is going to work on a ProgressBar while typing and the value of the progress bar change while typing. The progress bar jumps to the new value and I want it to move. So I thought about puting it in a "For ... Loop" but the whole form freezes.

I have a datagridview which fetches data from a local SQL server. Now, I have a setting called My.Settings.database_url which indicates the hostname of the SQL server.
Now, the problem is that if the host name is incorrect, instead of getting an error, the app just freezes. So what must I change in order to fix that?[code]...

I have an application which runs quite good, only once every X minutes it totally freezes, and even when running debug mode from within the VS2005 IDE, Visual studio becomes unresponsive. After pressing the pause-button to see where the app might be stuck, a messagebox saying "Unable to break execution" might pop-up after a minute or two. My app uses some timers, threads, and threadpool calls. So I'm afraid I got a deadlock somewhere, although I can not find it. Is there any way to find out where my app might hang?
Note: I synclocked every routine with a dedicated object, and for queues or arraylists, I even used the synchronized methods to modify them. I don't use recursive routines, so they cannot deadlock themselves. The strange thing (to me) is that all of my app hangs, none of the threads seems to be running, nor background, nor the GUI and even the VS environment.

In a function I have
Do Until PageLoaded() = True
{
Nothing
}
The problem is it freezes up the program and makes it unusable. I fixed it using timers but it makes my program real sloppy and hard to edit.

I'm trying to find a way to make backgroundworker do what's in the webbrowser. There is a time-consuming part in the webbrowserdocumentcompleted event that I want backgroundworker to tackle. Unfortunately, I don't know how to link that part to backgroundworker so that BW can do that job instead of webbrowser.
Here's what in the webbrowserdocumentcompleted event:
Sub WebBrowser1DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If CheckBox1.Checked = True Then
[CODE]...
The time consuming part starts from line 2 to line 30. My program freezes whenever webbrowser tries to do this job, so I need BW to do this specific job instead.
