View 2 RepliesI 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.}

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 am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

View 4 RepliesI have a label in my form which displays the text-content stored in a text file. However it is not able to display special characters like ", ', : etc. Instead it just puts a small rectangular box (same size as that of the text).
How do I get them to display these characters? Should I not use text files in this case or do I have to turn on some control-properties?
I've been working with my project. I make a quiz and I put check value for every label. If the user is correct the label with shows or else the label is in a hide status.

I've been through the example code provide to me, my textbook, google (how I found DaniWeb), and I've been over the code probably 50 times and the problem just isn't jumping out at me and it doesn't generate any errors or trigger the try catch, so I'm asking for fresh eye.[code]

For j As Integer = 1 To count

This creates the labels and text boxes in the form. Later in the program I would like to change the text within both the T1310() and T1550() text boxes and I am attempting to do so with the following code.
For j = 1 To count
status = OP930_SelectModule(j - 1)

The user has to enter the text in the textbox , to write a text user need to press the keys and release the keys. Write a code to count the number of keypresses and keyreleases and display the value in the labels.
View 1 RepliesIs there a way to display the contents of a drive (C:/) in a way similar to that of windows - pretty much just like this[url]...
Except that i need to show the files and - this is the part i really have no clue on - using the icon maybe using the Icon.ExtractAssociatedIcon method ?
So suppose there is a string: StringRamdom and you display it's contents in a listbox.
so listbox.Items. Add(StringRandom) but it should be displayed as A, B, C
not
A
B
C
So, I'm creating an array of labels. I have labels set up as:
labal1
label2
label3
etc...
I've declared the array as such:
Dim labelArray(5) As Label
Now, instead of assigning the labels one by one to the array (labelArray(0) = label1, labelArray(1) = label2, etc...), I was hoping to use a loop (there will be more than 5 labels). I have something like this, which obviously doesn't quite work:
For i = 0 To labelArray(i) = "label" & i Next
Is there a function that I can use to convert the labelName string to an object, or have vb.net see that as an object instead of a string?
How can I check if an array of labels is created before creating it?
The If Created dos not seem to work with an Array.

View 7 RepliesI 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'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 an ASP Chart (v4) which displays the data I need perfectly. I want it to show labels at the top of the data points and I am having some difficulty with it. Here is my code that works for both series but does not display the labels:
[Code]...
I'm seeing a strange problem with the labels on the X axis of my charts. I've setup two chart areas and aligned them (which displays fine) and the user can manipulate the chart by selecting different date resolutions (Year, Month, Day, Week, Hour) and different time periods.
The issue I'm seeing is that if a user selects say Months as the date resolution the X axis label display is inconsistent. If a fairly broad range for the dates is selected the X axis displays absolutely fine but as the date range narrows the X axis starts to duplicate labels ( please see the attached images). The second Image had a date range of 1st of May to 1st of August and as you can see the labels are duplicated. This is my first go with the chart control so I could be missing something basic. [Code]
