So basically i need to make a loop that only lets the user click it ten times then gives the answer to them.i was gonna use a DO loop that looks like this so far.
Dim counter as integer
counter = 0
Do until counter = 10
loop
and after that i'm kinda lost on what to do, i know that its needs to be if you click btnenter 10 times give the right answer and then your done.

View 8 RepliesI have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

View 1 RepliesI am writing a simulator program that gets its I/O from external sources with results displayed on a form. I heve composed a form, with graphics that look great, but when I call a loop to actually start the simulation, all my labels on the form go transparent and the 'stop' button I have created does not function.I have tried placing this continuous loop in the form code box and in a separate module but to no avail. Even just putting a clock on the form does not work - it prints to screen initially, but only refreshes when I run the cursor over the stop button.This leads me to believe (remember I am a VB novice)that a form is full of Subs that only run once on form load.So where is the main body of code placed that will run continuously; from where I can check the button status and update the form?
View 9 RepliesHow would a person stop a try loop once it has started a button click on the same "Form1'? Let's say in this example p = 100. If I wanted to stop it using a button how would I, I have searched Internet and found nothing that is working.

I have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.
I believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

In my application, I want to have 10 webbrowsers, which go to google like this.
For i = 0 To 9
Dim Browser As New WebBrowser
Browser.Name = "Browser" & [i]
Browser.Navigate("[URL]")
Browser.Visible = True
Next
So now I will have 10 webbrowsers aimed for google, right? So how do I make a loop that clicks the search button 10 times? I know I need to use member_invoke like this
Browser.Document.GetElementById("search").InvokeMember("click")
But I have no clue how to code the loop.
I have 1 picture box, and 1 image list with 11 pictures in it. I also have 1 button.
Heres what I want to happen:
I click on the button and the first image in my image list goes into the picture box.
I click the button again and the second image in my image list replaces the first image in the picture box.
I click the button again and the third image in my image list replaces the second image in the picture box.
how exactly could I make something loop until a button click event?
Like
Do Until
NumericUpdown.value = (numericupdownvalue + 1)

View 2 Repliesim creating a high score table. Although i dont know how to write to a text file.What i did first was i created a text file in vb's resources and thats about it.What i want the program to do is:when a user clicks e.g. Button1. then the programs gets the score from textbox1.text (currentscore) and textbox2.text (out of)
then saves it to the text file.I tried the following
Dim oFile As System.IO.File
Dim oWrite As System.IO.StreamWriter
oWrite.WriteLine(TextBox2.Text(""))
EndClass
I have the following code, which I run everytime I want to add a new line to my text file, but it is deleting the previous data in the text file every time I do it.
Dim stFilePath As String = "C:file.txt"
If File.Exists(stFilePath) Then
Else
File.CreateText(stFilePath)
End If
Dim ioFile As New StreamWriter(stFilePath)
ioFile.WriteLine("{0}: {1}", DateTime.Now, "test message")
ioFile.Close()
As the image shows i am suposse to create a For loop to cause the display to show with the button click.
