using a for loop i want to be able to pause it, display string in text box for 60 secondsthen move to the next loop,change content of the string and display it again for 60 econds.this should go on till end of count.i am currently using a timer in do while loop to pause, but instead of displaying the string contents in each loop,it adds up all contents in all the loops and displays them at the end of count,not what i want. i tried using 'sleep'funtion but its behaving the same.below is the code:
For i = 1 To count Step 3
'empty string

1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.
My program is supposed to display a randomly generated sentence on the screen (something like a screensaver) Then 'wait' for a random period between 1 and 5 minutes before cycling through to generate another sentence. How do I do that?

I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.
View 4 RepliesI am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.

how to put a pause into a script I am running and have it repeat itself :-)
View 1 RepliesI've been trying to figure out how to pause a process. It seems I need to use 2 different APIs: SuspendThread and OpenThread.I found some C# code at this link that was working for them.After I translated the code to VB, I get nothing when I run the code. I debugged the app and put a watch on the function.The following is what I got from the watch: Name 'SelectedItems' is not declared.[code]In order to work with the selected process, I'm parsing the Process ID. I then use that PID to get that process and then work with it.I sue this type of code often in my project and it works just fine, which is why I am confused that I'm getting that message from the watch.

View 8 RepliesMy problem is that I have a textbox that is filled with a line of data from an attached barcode scanner. I want to make it so when something is scanned into this box, another function is triggered (it clears the textbox and commits the data to a CSV file, so the user can scan another barcode). I was using a .TextChanged function so that when the text was changed in this textbox, it would commit it then, however the problem with this approach is that if the serial number is 77G8DS, then it will commit 7,7,G,8,D and S individually, instead of an entire string.

View 1 RepliesI am having trouble with an Access form which runs some VB code behind it. The form accepts lots of user inputs and these are then grabbed by my VB code to calculate a result. This all works fine but does take some time for the calculation to complete due to the size of the datasets. Rather than the user having to stare at the same screen and wonder what is happening, I have another form which pops up to tell the user the calculations are in progress. The problem I am having is that this window will not display properly until after the calculation is completed. It seems as though Access cannot handle displayinging my window whilst the calculation is being caried out.
Is there any way to delay the calculation in VB so that my window will display correctly? The calculation can then take place after this. Here is my code:Private Sub Calc_Click()Dim ccombo(11) As IntegerDim Total As IntegerDoCmd.OpenForm "calcsinprog"
I would like some kind of delay or pause here to allow the window to open properly before the calculations below.
ccombo(2) = Me.c2combo.Column(1, Me.c2combo.ListIndex)ccombo(3) = Me.c2combo.Column(1, Me.c3combo.ListIndex)ccombo(4) = Me.c2combo.Column(1, Me.c4combo.ListIndex)ccombo(5) = Me.c2combo.Column(1, Me.c5combo.ListIndex)ccombo(6) = Me.c2combo.Column(1, Me.c6combo.ListIndex)ccombo(7) = Me.c2combo.Column(1, Me.c7combo.ListIndex)ccombo(8) = Me.c2combo.Column(1, Me.c8combo.ListIndex)ccombo(9) = Me.c2combo.Column(1, Me.c9combo.ListIndex)ccombo(10) = Me.c2combo.Column(1, Me.c10combo.ListIndex)ccombo(11) = Me.c2combo.Column(1, Me.c11combo.ListIndex)ccombo(1) = Get_PostCode_Score(Replace(Me.TextBox1, " ", ""))

I have tried many different ways to make this work. Every attempt causes a pause where the drag operation is not recognizing the drop sites under it. There are many long narrow flowLayoutPanels that allowdrop of my button. I am basically wanting the scrollbar(vsFLP_UnitPanel) to scroll if the condition is met. It works, but for some reason there is a pause when the scroll begins.
Try
If e.Data.GetDataPresent("myButton") Then
Dim show As Integer

When I run this code, it does not seem to open the OpenFileDiaplog diaplg box, or if it does, it closes it immediately, and I get at index out of bounds exception at the " infileStream = getFile.OpenFile()"This exact same code works without problem in another application I am building. So maybe its something about the IDE environment?I think, but am not certain, that this code worked in 2003 .net. I then used the VS wizard to automatically convert to the 2005 environment that I am now coding in.
Dim infileStream As Stream
Dim getFile As New OpenFileDialog
getFile.Filter = "All files (*.*)|*.*"

My application first checks if an SQL Server is installed before it runs. If there is no server it installs one. Now I want the application to pause or exit during the installation, since its thread may compromise the installation process, or is it not?. How do I do this? The Sleep() mmethod may not help because I can't know how long the installation process would take.
View 2 RepliesI want to insert a pause between the display of one control (a button) and the display of another control (a label) on a windows form. Specifically, I want the form to load with the button (and other controls) displayed, then, after a pause of two seconds, the label to display. I have tried timers, and .Sleep() but the effect is not what I want. That is, there is a pause before all of the controls are displayed, and all (including the label) are displayed at one time. I want most of the controls (all except the label) to display normally, then, after a two second pause, I want the label to display (on the same form).

The problem of course is that the while loop causes a crazy infinite loop and locks the program down during excecution. How do i await the user input?
I have a form that has a webbrowser and two buttons in it. [code] This all works great but when the last line is run in Button 2 [code] another page is displayed before the data I am trying to get is available. There are more fields and another button to be pressed. However, because another page is loaded, I don't think I can just plop in the lines of code I need to manipulate the website because of load delays. Should I use VB's timer to delay a few seconds before running the next sequence of code?

Does it make more sense to allow the threads to finish execution and recreate them when needed or to just sleep them and then wake the threads up via Thread.Interrupt when needed?
