In Ajaxcontroltoolkit website they do a lot of async upates in their labels example: [URL] In this website, if you select Audi -> S4 -> Metallic, the Label below this DropDowns is updated automatically (before: [No response provided yet] after: You have chosen a Azure Audi A4. Nice car!) can anyone share a simple example of how to do this?
View 2 RepliesI'm trying to write a 'developer friendly' wrapper for the Windows API EnumWindows - the problem is that the API uses a callback function that gets invoked on another thread, where as I want my wrapper function to simplify this and make it more useful by working like any other normal synchronous function and just returning a value.
Now if the API just called the callback once that would be fine, as I would just call the API and make the wrapper function wait until it got a signal from the callback function telling it to continue... but the API calls the callback function over 100 times (once for every window handle that exists). The biggest problem is that there is nothing that indicates that any particular call to this callback function is the last one, so my wrapper function has no idea when it is safe to continue and return the list of window handles to the caller.
The only solution I could think of is to do this:
1. The wrapper function calls the API and starts a timer that waits 2 seconds before it raises the Elapsed event. The wrapper function then pauses until it receives a signal (ManualResetEvent)
2. Each time the callback function is raised by the API on a different thread, it stops the timer (so this is before the 2 seconds have elapsed), adds the current window handle that was passed in by the API to the list of handles, then starts the timer again.
3. If the timer reaches its 2 second interval then it is assumed that we are at the end of the windows because otherwise the callback would have stopped the timer. So the timer's Elapsed event handler is what signals the original thread (that the wrapper function is executing on) to continue as we now have a complete list of windows to return.
This works fine and does exactly what I want... but I dont like it.
I dont like forcing the caller to wait an extra 2 seconds after the API has done its last callback but more importantly I dont like assuming that the API will never take longer than 2 seconds between callbacks. In reality on my PC it is never anywhere near that long between callbacks, it is something like 200 miliseconds, but I have no idea how long it would be on a slower PC and I want this to be completely reliable.

I have question about Label.Text.
When run the code Form1 load together with Form2.On Form2 I have Label1.I need that Label.Text flicker or blinking.
I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.
I am programming in Windows Mobile SDK 6 using Visual Basic, i would like to know how to make a button open the smartphone browser with a specific website path (make a link)

View 1 RepliesI am using ASP.net(2.0) with VB.NET.
I have a User registration form. On that form the user supply all his contact details and he can upload a image with the normal file upload control in ASP.net.
This is my problem. If anything goes wrong on the page then i give the User a error message saying what he left out or what went wrong. But the page refresh when that does happen. NOW the link to the image the user selected is gone. NOW when the user fix his error he thinks that he is uploading a picture but he never did because when the page re loaded it removed the link to his image inside the file upload control.
Note, the user don't have to upload a image, so there will be no error when the field is blank.
I'm new to using httpwebrequest i've always just used webbrower controls but want to get away from doing that for obvious reason with that said.
I'm having it go to a wepage there is no login what so ever. but there is a cookie that holds saved data from the page. when in IE or any other brower you click an option from a combo box and it reloads the page and saves that data to a cookie.
CODE:
if you just do a httpwebrrquest it goes to 1 - Home what i'm trying to do is get to 25 - Page2 the cookie has the Sid number i'm been searching and reading for atleast 10hrs now and not even close to anywhere farther than i was. if i used Webbrowser it would just save the cookie for me automaticly but want to get away from hearing the clicking and wasting time of downloading all the pictures and stuff.
basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget"
Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.
Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
to"Hello. This is a test string."

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

View 1 RepliesI am wondering if there is a simple way to make the text to speech occur after the updating of label.text
If I have the following:label.Text = "words words" voice.Speak(label.Text)
I would like the label on the form to display "words words" before it speaks. I'm a beginner with vb, and the only thing I could come up with was to use a timer. Just wondering if there's a simpler/more sophisticated solution.
I have this problem but I already simplify the code as below:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "hello"
System.Threading.Thread.Sleep(5000)
'MessageBox.Show("hahahaha")
Label1.Text = "world"
End Sub
What I'm trying to achieve here is, after I click the button, the label1.text should change to hello, and after that to world. But I couldn't achieve that. Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.
