Error When Updating The ProgressBar Control When Accessin It From Another Thread
Mar 8, 2010I have a windows form with a progress bar and a button to start/stop the process. I am performing some action when clicked on 'Start' and updating the ProgressBar accordingly and its working fine. But when I try to click on the 'Stop' button when the process is going on, I couldn't access the Window. If I click for multiple times, I am getting (Not Responding) on the titlebar.
Then, I created a thread and run the function (which performs my task and update the ProgressBar) in it. I am getting an error that it could not access the control which is created in another thread.
Update ProgressBar From Another Thread (Thread Is Not A BackgroundWorkerThread)
Nov 18, 2009I have a program that runs for some time and I would like to update the user on its progress. The rest of the GUI is updated using Delegates and Invokes and such (Java is Soooo much cleaner in this regard - everything is thread safe!!), but there is no invoke method for the progress bar. How can I use a delegate to update the progress bar when there is no invoke to invoke!!
View 1 RepliesForms :: Thread Cannot Access Another Thread's Member Directly And UI Updating
Oct 18, 2011I have a small problem that I am sure is due mostly to my inexperience with threading. I have used simple entirely self-contained threads before, but not to a great extent. I understand the basic laws that surround them, such as how a thread cannot access another thread's member directly, and must use delegates.

Updating A Progressbar While Extracting Zip Files?
Mar 24, 2012I would be grateful if someone can help me with this task. I am trying to extract a zip file and update a progress bar as it is being extracted to the d: drive. I assume the progress bar has to be set to the size of the text.zip file and update the progress bar incrementally but not sure how to actually implement it. I have it in a "do Loop" but it does not seem to be correct. If anyone feel like helping I would be grateful for that.

ProgressBar - Getting UI Thread To Update While Reading Database
Aug 8, 2011I'm having trouble getting a progress bar to update. I'd be okay just with a moving marquee bar. Basically, I'm reading a database routine in a SqliteReader.vb class. I need to use the worker_DoWork routine, but I'm not sure how to expose my variables coming from Form1: graphData, graphComputations, m_debug to the worker_DoWork sub. How is this usually done?

View 6 Replies.net - Copy Local Directory Contents To Another Directory
Oct 31, 2011I have a straight-forward task I'm attempting to accomplish. I have the mechanics down, and need to hammer out the details but I'm stumbling across one small point. :)
This script is supposed to take the files in the local C:Temp directory, and copy them to a selected user's shared directory on the file server.
Protected Sub btnCopy_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnCopy.Click
My.Computer.FileSystem.CopyDirectory("C:Temp", "\MAVERICKVOL1Users" & ddlName.SelectedValue & "DESKTOPRECORDINGS", True)
End Sub
This script does indeed work (and I'm aware I need to create exception handling) but it only copies what contents are on the server's directory of C:Temp rather than the local source directory.
I'm using VB.NET/ASP.NET to achieve this.
How am I able to direct my function to use the local user's directory rather than the remote server?

Updating UI From Another Thread
Dec 14, 2011We have an issue with an application where we are making a call to an asynchronous process on LostFocus of a TextBox, the asyncronous process then needs to be able to update the main form UI (or display a dialog from the main form UI) while running asynchronously.We have thought about call backs and having it truely asynchronous but we need everything to execute in the correct order and this is for a data entry system where speed and accuracy of data entry is important.Example code shows what we are trying to do and if you switch to Begin Invoke the order of processing is not correct.[code]Does anyone know how we can invoke something else on the main form thread while is is still busy processing the LostFocus event?

Updating A Form From Different Thread?
Jun 13, 2010I have a VB.NET 2010 app I am writing that does a lot of work on a RS485 bus in 2 seperate threads. These threads are started as soon as the app is opened and run as long the app is open. I would like to have the threads update labels on the main (and only) form every so often based on what's happening on the serial bus. I know it involves invokes and delegates but I haven't found a straight forward answer on how to implement it.
View 5 RepliesUpdating A ListView From A Second Thread?
Aug 5, 2010I am writing a basic application to provide remote support to multiple computers over a TCP Stream. For example, if my brother/dad has an issue with their computer, rather than going over to help them I can just use remote support (Yes, I know Windows has Remove Desktop, and their is TeamViewer, ect. But where is the fun in using those =P)Anyway, it basically works by taking a PrintScreen of their computer, sending it to mine and displaying it in a PictureBox, then when I click the image, it records the coordinates of my mouse, sends it to theirs (Little Maths for resolutions and positions ofc) and clicks, then sends a new image.
My problem is, I want a ListView displaying the PC Info, like:
PCName - RAM - Free HDD Space - 32/64Bit - Processor Speed
Now, my problem is, I have a Class which does the TCP Server, and in that class when it Receives a Message, it calls the Sub "RunCommand(ByVal Command As String)", which then splits the String and works with it.So, for example, their PC would send the String "Info|DadPC|2GB|235GB|32Bit|2.2GhZ|" And mine would split it, and add that data accordingly.However, what happens is, nothing. If I put in "MsgBox()" anywhere in the Code, it shows it is all Split, and received correctly and everything is fine, but no matter what happens, it wont add to the ListView (Or anywhere else on the form, for example "GUI.Text = Info(1)" Wont work either)?
