Forms :: Pausing A Running While Loop And Wait For Certain Button Until The Looping Resumes?
May 17, 2010
I'd like to make a simple program where my form consists of a textbox and a button. Here's the ide in a nutshell:in form1_load I invoke the sub:
private Sub LoopingLesson()
dim i as integer=1
while true
[code]....
what I want is when i hits certain value, like let's just say i is divisible by 365, then the 'while' looping will stop, and a message box saying "target reached" appear. then after I click button1, the looping will resume until it reaches the next number divisible by 365, and so on.

I have an application that takes a long time processing information on a datagridview. So, I was thinking on a "please wait" dialog, with a progress bar in it.
Problem:
- I want it to behave like a ".showDialog" that prevents users to access the main form.
- But it shouldn't stop the code execution.
I tried to create a new thread to show the dialog, but this way it will not "lock" the main form... I want it to be always on top and focused, while open.

I'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.
Attached you can find the main screen:
Below you can find the main code.

Is there a way to play a wav file and then pause for 10 seconds and then it will repeat? I know it will be a loop, but the part that gets me is pausing for 10 seconds before starting the loop again.

When it comes to threading. I've managed to adapt one of JMcIllhinney's backgroundworker codebank examples to somewhat suit my needs, but not completely. I have a main form, and a second form that appears while I'm running through a for loop. It informs the user what is currently happening. I set up a backgroundworker that allowed me to continue to use the main form during the for loop, but the other "status" form was completely frozen, and any labels or graphics were shown as white boxes. I am struggling to figure out how to be able to move/interact with both forms while the loop is running.

I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.

I have a form with many buttons on it and I would like to loop through all the controls in a group control and find out which button is clicked.
I plan to use the click event of the button and I know it's easy to create a click event procedure for all of the buttons but would like to avoid that.
The group control is called GroupFilterButtons.

I have a VB2005 application where the PC waits for data packages from a target. Part of the data package contains what to do next. I am using SerialPort1_DataReceived thread to pickup this data package and "looking" at and extracting the "next step" data from the package then go do it. The issue I have is I must exit the SerialPort1_DataReceived thread to do this and not do everything inside the SerialPort1_DataReceived interrupt routine. In C there is something like this:

i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True }
ChildForm.Show
Me.Hide()
[Code].....
Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?

I am looping through a database with pdf locations. The application is button click event driven. The problem I am having is that I display a pdf. If the user clicks on the button then the pdf information is inserted into a database and the loop should be taking me to the next pdf. However, this loop does not seem to give what I need. What ends up happening is the first pdf gets displayed twice. I think mainly because I display the first pdf onload, but when I click the button it agrees and grabs the first item from the database. And it ends up falling behind because its restarting the query and I cant quite figure out how to get the button to catch the first displayed pdf, or skip it entirely since I am using a welcome pdf. So on the welcome pdf that is supposed to be displayed initially the user clicks agree and it agrees to the welcome pdf instead of just skipping it. I am not quite sure how to just move past the pdf.
public sub onload()
display the welcome pdf
end sub
[CODE]...
Now if I run the code without the loop it works fine. I just end up having to run the app however many pdfs I have in my database.
query data
display data
insert data
Windows.Forms.Application.Exit()
To display pdfs I imported the com control for adobe so pdfs get displayed like this:
axacropdf1.src = my.mysettings.default.readpath & pdflocation
pdflocation is passed from a query fill.
I think I have an underlying design issue which probably precedes the loop.

Im working on a console application, and i need my application to open message boxes without stopping/interupting/pausing the loop. I have been trying to make it open another application which spawns the messageboxes, but then every message box comsumes ~4MB RAM which becomes a problem when to many gets opened.

I have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.

I'm developing a big VB.Net Winforms application. Every now and again, processing or db connections take some time and therefore I'd like a wait cursor (hourglass) to appear sometimes. I know I can do it like in this thread (in case someone needs the code):Hourglass?- technical discussion - developer Fusion - ASP.NET, C# Programming, VB.NET, .NET Framework, Java and Visual Basic Tutorials However, I have LOTS of code and I don't know when the user will need to wait. So, what I'd really want is to tell my ApplicationEvents file or the like to globally intercept after say 0.3 seconds and turn the arrow (default cursor) into the hourglass and at the same time disable mouse clicks and the like.

I have 2 forms, form1 is my main form and form2 is a "Do this or do this" form (Form with 2 buttons like a are you sure form). When the user tries to close form1 if their is more than 1 tab open, it shows form2 which ask if they want to close the whole program or just the current tab. How to revive what button the user clicks on form2. How would I need to do this?
''Form1:
Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If (tc1.TabPages.Count > 1) And (My.Settings.AskClseTab = True) Then
If frm_Closemain.ActionTakin = "Exit" Then
GoTo Cont
[Code] .....
The problem: as soon as the form loads it becomes "Not responding" I believe this is caused by my do while loop, what other way could I go about doing this?

In my program, if something goes wrong an ErrorForm is supposed to show up and tell what was going wrong.
And if the error is a "fatal type", then I want the program just display the ErrorForm (which gives some information about the error), wait for a button press, and then close the program (terminate run).
In case of error, the form is displayed.. That's good.
But as the program is supposed to terminate after showing the error form, the error form disappears immediately after showing up (so it doesn't allow the user any time to read what's going wrong).
How can I make the program wait until a button press (on the error form) and then terminate?

I designed a application on vb.net 2005. Some of the forms in this application has databindings controls. Now when such forms loads it takes some time. I want a splash screen containg "Please wait" message to appear till the form loads and the wait splash screen would be shown for every several forms in the application not only before the start up form.
