I am a new vb.net 2005 user and new to this forum.i need to know how u can pass a counter from one form to the next.am developing a computer based test and questions are on different forms so i need to know how the mark for a test can be maintained and added to from one form to the next.
View 6 RepliesHow do I get my form to display a simple digital counter? I have a "record" function on my program:
Private Sub Button13_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
End Sub
I want to have a simple digital counter display while the program is recording. That way the user can know how long the audio is so far while recording. Then when the user is done recording, the timer will stop.
I've got a project that generates a sql query and returns the results. I want to place a time/counter on the form that shows how long it takes to return the query from the server. Basically to count up in seconds from 0 while that sub is executing. Would threading be the best way to do this or is there another way that I'm missing?
View 2 RepliesI would like to know how I can read a number from a text file then multiply that figure by one and write that back to the original text file, I'm trying to make a counter to keep track of how many times my forms are executed. The information will then be used to determine the success of my apps with in our company.
View 1 RepliesI have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
Most of my experience in Visual Basic programming is in VBA. I'm currently trying to build a VB.NET Windows application that basically consists of a form that has one button and one label. When the button is clicked, the label should serve as a "counter" that counts from 0 to infinity until the user closes the window with the "x" button. I do this by putting a loop with a sleep statement in the onclick sub. The loop iterates the integer that is displayed in the label and does a "Me.Refresh".The problem is when the window loses focus. When it loses focus (when I click off of it), the counter stops. Even when I click back on it, the counter doesn't resume.

View 3 RepliesWhen working with a collection of forms that the user must step through, is it better to pass the data foward when creating a new instance of that form, or is it better to call a function from the previous form? I have some code written that calls the previous routine, and it looks ugly, and I can't quite think of a reason why it was done that way. The only reason I could come up with was if the data was large, and there was a good chance that the user wouldn't use the data except in a special case.

The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.
I want to pass variables from one form to an other. The variables i I need in the second form( called" Hulsview") are :" hulsbreedte" and" hulslengte".

The value selected in the combobox on on form1" hulsbreedte = HulsBreedte1.SelectedValue" returns always 0 in the textbox on de second form.
