VS 2005 Several Labels In Same If-condition
Apr 6, 2011
I'm currently trying to make a beat generator, which allows you to add several labels (boxes) onto a panel, and then sound will be played when the "play slider" reaches the same x-value. However, i can't make the slider find the boxes.
OK, so this is what I've got so far! Clicking my button, a label named sound0, sound1, sound2 is added to my panel_back (which is the background of the player)
Private Sub btn_addkick_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_addkick.Click
Dim tempsound As New Label
[Code]....
It gives an error at the If-statement. Am i doing something wrong with just this if-statement, or should I do something different when adding labels to the panel?

I have a form where I bind the Text property of several labels to various columns in a datatable. A couple of the labels get updated as a result of user selections, so for those labels I set the UpdateMode of the databinding object to 'OnPropertyChanged'. When the user makes their selections, I change the text property of the label - and indeed I can see where the text property changes.
However, when it comes time to save the data, I do a GetChanges on the datatable looking for rows that are Modified - and I get back nothing. I've tried explicitly calling the WriteValue method of the databinding object after I update the text property of the label. Still nothing.

I have created a page containing the Wizard control. It's a very simple one. User selects some data on the first page, clicks Next and then has a choice of Previous or Finish. When they click Finish the form is submitted but, for some reason, the font size of all my labels increases. There's nothing in the code of the Finish button that would do that.

I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.

I have a open and file save dialog which I use to open and save file. There are also some labels in the application. During the time a file is open or saved, the file open /save dialog becomes blurred by the background labels. Is there any way to prevent this? The attached pic is given as an example to explain the dilemma.

I want to build a system that will take the input from an electric guitar and capture the frequency of the sound. and when the frequency is captured, the system identify the chord, and create new controls to represent the audio frequency. i want to use the label as the controls. so when the controls is created, how can i know that the user is click on what label. is there something like label1.click in vb 2005 express? then when the label is all created, i want the system to read all the labels integer as the sound of midi. so i have to assign what integer for what sound.

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

What is the correct syntax to go to the next sequence in a loop if certain conditions are met bypassing the contents.
I am using goto and inserting a line number which is probably not the best way.
I.E. My syntax:
For i = 0 to 100
If i = myvariable goto 100
