I have a datagrid which receives updates for every 1 minute from the database. Whenever it gets update my whole form gets freeze and I cant do anything. To add on when first I log in also the log in page gets freeze because the form is being loaded during the first time.
View 1 RepliesI have a windows forms app (32 bit) written in VB2010 which occassionally hangs in windows when minimised to the task bar You click on the icon on the taskbar and it will not come back up on the screen
No other modal forms are open in the application when the hang occurs Other programs respond OK
I ran Process Explorer against when it was Hung but do not know how to interpret the stack page, or even if it is helpful STack page with my application selected and Threads tab selected with CSwitch Delta column sorted descending. Then double clicking the top entry (my application .exe)
Note: This is running on an x64 machine, but also hangs on x32 machines

View 5 RepliesI have a visual basic program wherein i fetch information from two textboxes format the output of the textbox in the required form and then make the output come as desired I use two arrays to read textbox 1 and 2 separately and then i use for .. next statement to perform the same action for all the lines in the textbox 1 and 2..
Both of them have equal no of lines..I have also give a progress bar in the form and assigned the max value as the number of lines and i have given the incrementation within the program for the progressbar..
When i run the program it runs quite well for certain instant of time and the progress bar also responds according .. After some interval of time the form hangs and the progressbar also hangs at that place..Later after some more time the form is back to normal and the process is in finished form with progressbar at 100%..
Is there any reason why the form hangs..If there was a major problem i must have not got the output at all but i do get the output after certain interval of time..Can this problem be solved??
I made a program that backs up data from the My Documents, Favorites, and Desktop folders on Windows XP to a server. When the data is brought down from the server, it brings it down in Windows 7 format. So, for example, the directory to My Documents in Windows XP is "C:Documents and SettingsusernameMy Documents." The same directory in Windows 7 is "C:UsersusernameDocuments."Everything works fine in terms of putting files and folders in the correct directory, but when bringing the data down from the server, the program sometimes freezes up and doesn't ever seem to get out of that state. It also makes the computer very slow and unresponsive after a while. Does anyone have any idea why this would occur?
Below, I have a code snippet of my copying code. I include a sleep command and a DoEvents command to halt the thread for a very short duration of time in order to make the UI more responsive.[code] I believe I may have to use some multi-threading to get this to work properly, but I've looked it up and cannot find out how to implement it in my program.
I am using the following code to receive data from a Public Address Controller.the programme sends data...waits for a reply....send more data...waits for a reply..etc.

is there some way of cancelling the BeginReceive after a delay so that the programme can carry on and inform the user that something is wrong and terminate gracefully?
Creating an application that uses both namedpipes and TCPIP connectivity to pass data between 2 legacy applications.
When there is actual data to pass everything works great. But when the application is looking to see if there is any data to read from the named pipe side and there is no data, the Peek hangs until there is data. Is there a problem in the way I have it coded or is there a timeout that needs to be set?
Code:
'
' declarations
'
Private in_pipeName As String

Edit 1: Uninstalled & Reinstalled Edit 2: Same problem. Seriously? Yes.I am having a problem with msvb7.dll eating 50%+ cpu on my dual core system. This usually lasts 10-30 seconds or so, during which time the IDE is non-responsive.
This occurs when I do pretty much anything in the text editor, and can be replicated by simply adding blank lines to a function, and then deleting them. Or pasting some code. Or... lotsa stuff.
SP1 installed I had DevExpress' refactor/coderush, components, and codeit.right installed, but have removed all 3 of them. (I had installed the latest version of Refactor Pro! (9.3.4), perhaps the day before)

I have a really simple form with a button that fires a Sub I created which gathers data from ActiveDirectory and adds it to an Excel Sheet. The problem is, when I click this button the whole form hangs. So I figured the operation that gathers the data and adding it to the Excel sheet should be run in it's own thread, so that the form won't hang. Possibly it would be great to add a progressbar as well. The progressbar however is located at the Main userform that starts up once the projects is run.
I've got one MainForm.vb and one CodeFile.vb. I want most of the code in the CodeFile.vb so it's tidier.
MainForm.vb
Imports User_edit.CodeFile
Imports System.ComponentModel
Public Class MainForm
Private Sub btnImportData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnImportData.Click
[Code] .....
Notice the ExportFromAD Sub I've got in the CodeFile.vb. This is what is actually doing the work. In the For each loop that adds data to the Excel is where I've put the MainForm.MyBackgroundWorker.ReportProgress(i * 10). Problem is, it doesn't actually update the label on the form. Which I find pretty weird because the form isn't really hanging or anything. Is it trying to access a different thread or something? Meaning, the form is run on it's own thread which can't be accessed from my second thread?
Yesterday I worked on an MVC 3 project in Visual Studio 2010 and then shut down Visual Studio before leaving work.This morning when I try to load the same project in Visual Studio the project hangs.

As an update rolls out in one of my applications, I would like to implement an update checker. My situation is that, when a user clicks a drop down item called "Check for Updates", I want it to check for updates. My application is simple, I don't publish. I upload to a mediafire and put the download link to my blog. The only file I need in my application has always been the .exe file of the application itself. My question is, what is the simplest and best way to implement a update checker?
Example:User is using v1.1 and checks for updates. He clicks the "check for updates" and a popup shows up with yes, update available and is a msgbox yes or no. Yes, would allow the user to download the update. No, closes the msgbox. If there is no update available, then a msgbox shows "You have the current version". If the user is offline or cannot check I would like to have an exception to show why he cannot check.Basically, working with the download aspect and everything else is familiar to me but I have no idea how I can check.
Try
My.Computer.Network.DownloadFile("downloadurl", "downloadlocation.fileextension")
Catch ex As Exception
MsgBox(ex.Message)
End Try
I am a newbie to VB.Net. Before, I did programming in PHP.

I want to make the same thing in VB.Net.
