im looking for a way to have my program wait a certain amount of seconds before it goes on to the next command, ive tried the sleep command but that freezes up my program and i cannot let that happen, ive heard of using timers as a delay but i don't really know how to do that.
View 4 Replieshow do I delay my program without freezing? I am sure there is another way to do this without timer.PHP uses sleep(). What do VB use?I tried some Delay or Sleep function but don't seem to work..

View 17 RepliesI 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.
View 7 RepliesI am puzzled by a delay in my data appearing (sql sever) when I open my program. (this can be around 5 to 6 seconds). If I open it a second time it appears instantly, have I done something wrong, or not done something. I have connect to a MS access database that connection is instant always.

View 2 RepliesI have a code which adds each line of a textfile to a List(Of String).I have around 1.5 million entries in the textfile. It adds it to the list in like 1 second. However, I'm trying to add all the users to a threadpool to do a certain function. So I try:
For i as integer = 0 to list.count - 1
The list has like 1.5 million entries so the GUI freezes untill it all finishes in like 5 minutes. How can I make it go faster and not freeze the GUI?

I have a form with binding sources and a method for saving the data.[code]I was testing to see what would happen if the operator tried entering duplicate data in the primary key field. They exception occurred as I expected but the program gets stuck at that point. The exception messagebox just keep redisplaying when you click OK. I'm fairly new to .Net, but this code is how the help files show updating a TableAdapter using the "Try/Catch".
View 10 RepliesI am writing an ASP.NET class that interfaces with an external application. The flow of the transaction between the web server and this application is as follows:My object writes a file to a directory.The outside application detects this file and processes it. This can take between 1-5 seconds.The outside application writes a response file to the same directory.My object detects the response file and parses the results.The 1-5 seconds it can take for the external application to process my file is my problem. The most straightforward way to wait for the file seems to be something like this:
Do While Not File.Exists(f)
Thread.Sleep(500)
Loop
Of course, Thread.Sleep() completely locks up the rest of my website until the outside application processes the file. Clearly, this is not a workable solution.How can I effectively "wait" for my file to be processed without locking up the rest of my website?

I was messing around with the listview Control first,, And when i got it working i thought what's this backgroundworker thing,,so i read up on what info MS had on the MSDN page..and slapped it in here..and i thought i had it working ok until i tried to move my project application to the side to reply to a instant message i got..and then i noticed that it froze up .and looked like it was using alot of system resources,But wait let me back up just a bit.originally i was trying it with a fairly small number of items, and then i seen on here where someone had posted a rather large index for testing his app with,,and while trying to load that list that's when the issue was noticed i don't really plan on loading a list as big as that test index was but, I would still like to know why the program did what it did using the code below.I'm not really asking for it to be too altered, i kinda like all the controls i have in it the moment,, and the way it loaded as well.

I think this might be related to threading (which I havent really worked with)..
In this app I'm developing, I am downloading a file when a user clicks a button. However, since the file is 20mb or so, its kinda unfortunate that the application hangs while doing it...
Do I have to go into multithreading here, or is there a simpler solution? (Or maybe multi-threading is simple?)
I have a simple program with a web browser control and a button that causes it to navigate to a certain web page, as well as an input and another button for entering a url directly.Everything was working fine until I started messing with the document completed event in the control.The form loads a url initially and after that 80% of the time it freezes when clicking the button or entering a new url. I deleted the document completed code and now it still freezes a majority of the time.
View 12 RepliesI'm working on a project where I make a automatic messenger from VBnet. I want to program a simple one that responds to certain words or phrases. However, I only know the rough basics of If...Then commands. I have a lot of problems:
1. How do I make it so the messages typed in the box actually goes up into the script box when I press send?
2. How do I program a slight delay in the computer's answer?
3. How do I set a name to the computer and to me?
4. How do I make the script goes into scrolling when it runs out of space.
5. If possible, when I type an equation in the box, can I program the computer to solve it and display the answer? I'm a beginner so I don't really know the overall organization of this project. However, I would like it to remain as simple as possible.

Is there another way to get your program to "Sleep", without freezing it?
View 4 RepliesI am a VB hobbyist and a new one at that. I am trying to create a transition effect in VB.NET 2008 when a certain form closes. The transition will take the form's current BackColor and slowly drop all the RGB values in it to 0 via a loop, obtaining a Fade to Black transition. I was able to come up with the code below. It works great. Maybe too great. It goes so fast that there is no transition. To the human eye it looks like the screen just went black instantly. Is there an easy way to enable a delay or pause in the below code to slow the loop down so that the end user sees the transition, and not just a quick jump to black?

I have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?

View 9 RepliesI am using serial port to send packets in a form. There is a delay between two common packets, say 20 seconds. I used to use sleep to delay 20s before the second packet send.But sometimes I need to send a special packet every 4 seconds to keep device alive before the 2nd packet send. But during sleeping I cannot do anything.Per a suggestion yesterday from an expert, I changed to use timer solution. I set Timer1.interval = 4,000 and Timer2.interval = 20,000 and enable Timer1 and Timer2 after the 1st packet in Form1. After the 2nd packet is read to buffer, I use "while" to wait there until 20s overflow in Timer2 to send this common packet out. At the meantime, Timer1 is supposed to overflow every 4s to send the special packet. Now the problem is:
