What is the best way to create a delay between interations in a loop, somewhere around 1 to 5 seconds?Example:
do
'Do something
Delay number of seconds?????? How do I do this
[code].....
i want to do this with the delay of in interval with the loop of 10 times.
for n=0 to 10
label.text="0"
time delay of 1 second
label1.text="1"
end loop
But when i m using executing the loop completes it iterations and timer just show work in last iteration.
i have a web browser control, that refreshes pages on a loop after calling a few subs, i need to create a delay in the loop so that the page has a chance to refresh and redisplay before it loops again. i tried the code below, but it seemed to freeze the entire form, elements including, so the web browser didnt refresh before the loop, so how could i create a non form-freezing delay for a loop?
For count = 1 To 20
WebBrowser1.Navigate("URL")
simcheckcheck()

I tried to convert my VB6 code to VB2005 and it seems like some syntax cannot be use. I had tried to make it work but it still failling me.how to create a delay timer which can delay up to 5 hours and this will repeatly in 10 loops.

I'm using Visual Basic 2008 Express Edition.I'm working on a class. At various points, I want to insert a delay between executions of the code. Nothing terribly large. Around 50-200 miliseconds. It doesn't seem like much, but it makes the program run better. I'll probably randomize the length of the delay later between those two marks. So basically the code would go...SomeFunction()timer delaySomeFuntion()I have the timer declared as
Private tmrTimer As TimerAnd each place I want to use it, I simply redeclare it. Or I might add it to the constructor of the class. Either way. Just thinking adding it to the class constructor would probably be a better idea.
tmrTimer =
[Code].....
End SubUnfortunately, I get the error "Handles clause requires a WithEvents variable defined in the containing type or one of its base types"Now remember, this is all contained in a class, so theoretically speaking I can simply move the class file from project to project and reuse it, without ever having to worry about how the class works. Reading through the Timer specifications, I probably need to do some cleanup on the timer after I use it. Am I correct in this?
I have a Nag Screen that I am creating, and I am wanting to create a delay before the OK button is enabled allowing the user to proceed.
Is it better to use a Timer event or would a 'For I = 1 to 20000"
loop be the better option.
All this timer would do is Enable the OK button, thats all.

View 7 RepliesI am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.
View 2 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.

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:

Is it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.
View 5 RepliesMakes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I want to loop through my datatable column called SDESCR and created a string that looks like this.

I have a button and text box. Every time I click on this button a number increments in the text box (textbox1). So far so good. Also on the form is another button called 'Submit' and three more textboxes. (textbox2, textbox3 and textbox4) What I want to do is every time I click on the submit button the value in textbox1 will be placed in the first textbox (testbox2) I will then increment the value in textbox1 and then hit submit again and the current value will be placed in textbox3 etc. The question I guess is how do I create a for - next loop that will increase the textbox?
View 8 RepliesI'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.
For i = 0 to 52
originalLabel.duplicate ("duplicatedLabel" & i)
next i
So later I could go through all of them...
For i = 0 to 52
//... some logic to determine color... then assign it somehow
duplicatedLabel & i.backColor = Color.red
next i

I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

I've got an app working semi-background stuff in the GUI thread. Another thread won't work and a timer won't work. But I want the app to be responsive while I'm going my 'background' work.I cound use application.doevents - but that gives me 3 bad choices:
-loop with no sleeps - end peg an entire CPU (my task waits on stuff besides calcs & I/O so this matters)
-loop with a sleep - then the app slows down
-Try to make a 'smart sleep' loop that speeds up when lots of messages happen (check for messages in messagefilter function)
[code]why I can't use application.run, or threads, what I want to do is handled the OnUnhandledException event, then leave my app open for a while while some winforms stuff closes it down gracefully and tells my watchdog program to restart the app. after allowing the user to finish a critical process, too. Yes, I know people thing that a program getting OnUnhandledException deserves to die (obviously MS), there are 'dangerous' things that could happen; none of them are as dangerous, however, as the wrath of my users. Looking for vb.net sourcecode exact translations of the above two functions.
threads that watch folders and process files. This works fine, but every time needs change to add a new folder or just change some existing rules I have to go in and change the program. I want to builda front end that storesprocessing infofor each watchfolder. The program would then read the configs and build the threads based on them. I cannot find a way to loop through creating the threads.
View 8 RepliesI have a string where I have created a template so to speak.
{
Dim myvariable as string
Richtextbox1.text = Richtextbox1.text & "The dog jumped over the" & myvariable & "to find the fox."
}
I have a list box that contains a list of options that loads into the variable example: fence, bucket, etc.
So the sentences would read like
The dog jumped over the fence to find the fox The dog jumped over the bucket to find the fox
Right now I have it coded to display into a rich text box but everything is in the same rich text box.
I'm trying to load the string into an array at the end of each loop this way I can then have each sentence separated.

I want to be able to reveal and then populate a certain number of labels. The inefficient way would be to SELECT CASE on the number of labels required and then populate these in turn. I am looking for something like this:
For i = 1 to RequiredNumOfLabels
Label & i.visible = true
Label & i.text = DataTable.Rows(i).Item(2)[code]......
is the problem as after the line is executed, lbl still equals nothing.The reasoning behind it is that I was trying to create an invoice generator in vb.net and I was hoping that this would be a simple way to do it - count the amount of items in the order, populate the labels with the names of the items, reveal that many labels.

I'm trying to create an app with a backgroundworker to enable canceling a loop, but it won't work as I hoped it would.When I debug right after the line ThreadWorker.RunWorkerAsync() the programm goes directly to Private Sub ThreadWorker_RunWorkerCompleted and skips the Private Sub ThreadWorker_DoWork part, where of course the actual code is in (I've left that code out, it's about a 100 lines and without BGW it works).Does anyone have an idea what could be wrong with it?

I'm doing a small tool that basically wipes the document properties of each .*doc file in a specified folder. The code is working, however, if the document is already opened, I'm presented with a text box asking if I want to open a read only copy etc. I want the code to abort if that happens and rather write it down in a log file or something. And just move on to the next file. How can I do this? I'm talking about editing thousands of documents.
