Ive got a container with a bunch of child textboxes stacked using dock top. My code updates the textboxes and they vertically expand/contract etc. I'm thinking that my code might run faster if I turn off the layout refreshing until all the updates to the textboxes are done.
I'm getting confused with what I'm reading about suspend/resume layout - do I need to suspend for ALL the child controls, then go through them all at the end and Resume individually?
Is it possible in visual basic to suspend and resume processes. As in entirely pause a process (threads)?I mean an external thread. I'm using Visual Basic 2010 Express btw.
I have a a main thread and another background thread that does some work (see below).I want to do something within my worker thread and then wait until some other event happens in the main thread before continuing. How do I do this? I thought I could use ManualResetEvent but I can't get it to work properly. I'm a bit confused about the Set, Reset, WaitOne methods and where exactly I should call them from.When the worker thread is suspended it shouldn't affect the main thread.

Looking for a solution to pause and resume a thread. When I use suspend and resume it says its no longer supported. Here is the code. I'm just trying to get it to cycle between two "do until" events.
I dynamically add picture boxes to a vb.net form. However, when I add the new picture box, it is always under/below/behind the picture boxes that I previously created. Is it possible to change it so that the newly created picture box would always be in front of the others?
Is there a way for suspend a process using vb.net. For example, while my program running background, it should wait for other programs (like X.exe) run and suspend them. With my permission (X.exe) will continue to do its job. If i reject, then terminate them.
how to lock or suspend the form when i call another form and until that is finished this form should be locked.example: i got frmAddEditClient form and frmViewClients as another form, now i got list of clients in frmViewClients and i will select a client i would like to edit the client profile ( for which fuction is defined in frmAddEditClients) so on click of btnEdit in frmViewClients form i place code to [code]now i got everything working fine but i shud make the frmViewClient form to lock so that untill edit operation is done user should not change anything i.e is not selecting other ClientID. in the frmViewClient form.Once edit is done frmViewClient is unlocked and then clientId is refreshed.
I am trying to use a separate thread to handle specific events in VB.Net. The idea being that I do not want the main application to be held up if a particular event handler takes awhile to finish. How do I get my main thread loop to suspend the thread while allowing it to handle events when they occur?When I create a Windows Forms application, there is a UI thread that handles the UI events. I do not imagine that this thread is continuously polling some variable to see if someone has pressed a button. I imagine the thread is suspended until the OS tells it there is something to do. I was trying to figure out how to ensure that my event handlers were not being executed by the UI thread. From what I have read, I can do this by raising the events from a different thread. But what does that thread do while it is waiting for other events, just exit?
I wanted to know how to create a thread that works like the UI thread, only it processes the events I want it to process. I am not sure how events work in .Net. I understand that event handlers are run on the thread that raises the event. I believe that .Net allocates threads from some thread pool to process events such as timer events. I am not clear on how it works, though, and what those threads are doing when they are not handling events.
I have created a windows service in C# .net and now I want it to alert me if its going to shutdown. For this I make use of Dispose/Unload events but now I want if the services are stopping due to system shutdown process it will alert me.
I have a DataGridView that uses a BindingSource that has a DataTable as it's DataSource. If I filter the DataGridView by using the BindingSource filter on a particular column, then I change a cell value in that same column the row disappears. For example, if I filter my "Shipped" column which contains CheckBoxes to only show True and then I set one of the CheckBoxes to False the row disappears from the DataGridView.
I do not want the row to disappear until the BindingSource filter is changed or removed. How can I suspend the BindingSource filter and then resume the filter if the filter has changed? I want it to work like MS Excel's filter. If you filter a column in Excel to only show cells that equal "Apple", then change the cell to "Banana" the row still shows, but if you change the filter the "Banana" row is removed. This how I want my BindingSource filter to work.
[code]I get an error that the connection to the IMAP server has disconnected because the suspend event is not triggered until the computer wakes. How do I get the trigger before the computer sleeps?
I'm using Visual Studio 2005 (with Visual Basic) to create my own personal web site. I want to include a page that has my resume, but I don't want the format to be affected. What would be the best way to do this. I thought that possibly putting it in as an image might work, but I haven't tried that yet.
After I get this done, is there a way to add a button so a user can download my resume?
I have a case where I need to resume execution on the next line after an exception. Is there no way to do this using the structured error handling? I realize that I can go back to the "On Error .. Goto", but I can't believe there's not a way to do this with structured error handling...

I know that even when the timer is disabled, it still keeps on accumulating so I need a way that when the timer is paused, the timer doesn't keep on accumulating and when the timer is resumed, the timer continues from where it was when it was paused.
I'm working on a project in VB.net which takes large text files containing T-SQL and executes them against a local SQL database, but I've hit a problem in regards to error handling. I'm using the following technologies :
I need something that will log the time the computer came out of standby, or the user logs in the first time from a reboot.
Basically, I want to time computer usage but in simple terms where computer is being used after waking or after rebooting.
So, All I need is a detection scheme. Does windows provide that? I am probably targeting .NET but can do Win32 API. Or do I have to do anything like that all?
I am thinking if I make a service, windows will handle the launching of the service and that way I can detect usage. But is that the most efficient way?
