Program Freezes Over A Period Of Time (5sec)
Mar 15, 2011
Is there a way to code, so that if your program freezes over a period of time (5sec), it just stops trying to do it, and goto something else.
"On ERROR" wont work, since its not a error. "Try" doesnt work ether.
Its because I'm am programming something that can login to a router thought telnet, and sometimes the telnet ActiveX doesn't read the buffer or the line proberly, so when the .GetLine() func is called, it freezes. And i want away to goto another point if it keeps freezing for more than 5secounds. The telnet ActiveX that, I am using is Dimac w3sock.

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

I am trying to display a dialog for a period of time. if the user is not present, I want it to close and perform a task. I am using a background worker, which is supposed to simulate a button click. It performs the button click fine, but the dialog never goes away.
Private Sub Backgroundworker_ProgressChanged() Handles BackgroundWorker1.ProgressChanged
If Me.BackgroundWorker1.WorkerReportsProgress >= 100 Then

take a shot from a camera every last day of the month at midnight. I know how to to take the shot, but I don't know how to generate an event repetitively after a time period. I thought about to calculate the time between now and the next shot time, but how to run a method after a time period?

How can I loop through each date in a given time period so that I can add those dates as a column name in a table. I want to create datatable with the person's name and hours he worked in a given time period. The user will select the dates and I want to show each day/date in that table as a column name.

I have set up a simple quiz where you drop answers to the correct question. I have implemented a system where the are 18 text boxes (9 for questions, 9 for answers) and it can be customised but I want the questions to be able to be 'saved's since it in another form the if I give them special names when I close the form and open it again it has lost the values. Is there a way to remember the variables for a set period of time (cookies?) or if not just for that session?

I have already made an algorithm for the problem but it still got a trouble.Suppose that I have the recap of schedule (contains on gridview named GV):
TimeStart TimeEnd TotalOccuredOnThisTime
----------------------------------------------
08.00 08.50 1
08.00 09.40 43
08.00 10.50 2
What I want to get from the algorithm is, to count the time that occured on the same period, e.g. on the time of 08.00, it's occured 46 event (see the yellow colored row).This is my algorithm:
Dim ColumnLength As Integer = GV.Rows.Count
Dim TimeStart(ColumnLength - 1) As Integer
Dim TimeEnd(ColumnLength - 1) As Integer[code]......

I am developing an application that prompts an user for doing certain tasks in a form. What i want is that a certain message should be popped for a certain amount of time and then close (probably say 2 seconds or so). I tried doing it with message boxes but they do not close on their own as they are designed to be modal (to wait for user command ). i do not want to display the text in a textbox of listbox. Is there a certain way i could do this.

I have looked through couple of threads about making the trial application to be expired within certain time. Most of the advice is to set a timer and store it in somewhere in the system with encrytion. Then later decrypt and compare with the date installed in the system.

I know about DateDiff and TimeSpan. I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.
I save the date in the registry like this:
Application.UserAppDataRegistry.SetValue("Date", [Date])
I then made a sub to calculate the differences:
Private Sub Calculate()
Try
Dim DateGen As Date
DateGen = CType([Date], Date)
Select Case TimePeriod
[Code] .....
As you can see, based on the difference between these dates ( today's date and the registry date ), a sub gets called and the program continues. Unfortunately, the minutes and hours never calls the RandomAlpha sub. How can I calculate the difference in minutes, hours etc.????

I have the below code. What happens if the Upload method takes more than one minute for completion? Does the timer kick off another call to the Upload method immediately after one minute is over or Does it wait until the method finishes executing? I am implementing this as a windows service.
Protected Overrides Sub OnStart(ByVal args() As String)
Dim tmr As Timer = New Timer(New TimerCallback(AddressOf Upload), Nothing, 1000, 60000)
While Not tmr Is Nothing

I'm trying to connect a remote mysql database. I'm doing it from a vb.net 2005 application with a connector mysql.data.dll What's happening is, suppose if I try to connect thrice it connects twice and once throwing an exception that says A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. there's nothing wrong with the code, otherwise it would never have connected

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.

The program starts. When I click the Start button the original form disappears just as I intended, but then it just hangs there. No picture shows up. The CPU heats up and gets louder. It freezes and I sometimes have to CTRL+ALT+DELETE just to exit the program.[code]

I have a program that has multiple tabs, with roughly 100 - 400 controls of varying types on each area. The program takes about...4 seconds to load, which I don't think is right.I did a few memory tests on the program startup, and idling it. At startup, the program uses 100% CPU usage, and 102mb of RAM, but then the form displays, the RAM drops to 20%, and CPU at 0%.Changing a Tab locks the program up for 1 to 2 seconds depending on the tab, and memory fluctuates.Am I doing something wrong here, when a program form has literally over 500 controls of many types, spanning 6 tab pages, or should I be doing something different?
