I need to use an updatepanel to set a labels text to a sqldatasource value every 5 seconds. I don't really know how to use the updatepanel, I also can't find a way to run a script every 5 seconds. I'm using vb.net and asp.net.
View 1 RepliesI just want some labels' visibility to be false until a few seconds pass, and then be visible.
View 3 RepliesI am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="10000"></asp:Timer>
<asp:updatepanel id="upParent" runat="server" UpdateMode="Conditional">

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?
View 1 RepliesI'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.For example, I have 4 textboxes currently that have Address, City, State, Zip.I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID. How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.

Can I do this?
how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I am trying to wrap my head around getting some blinking colored text and lasting for 3 seconds on the screen. I'm creating a game where you hit submit and if the answer is correct a label with popup and blink 3 different colors for about 3 seconds also a groupbox background color change. I have found many different ways on here how to do the blinking text. I just can't figure out how to do it for 3 seconds and then disappear. Here's a general idea of the code
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I want to save a string of text to a file every 1.4 seconds or so, and each day at midnight I want to create a new file for the days log data so I keep the file size down. The file stays open the whole time so that it is ready to accept data from several different forms which call a function (SaveToVoltsLogFile(str)), so I open it at module level like this:
Dim fsVlogStream As New FileStream(EVENT_LOG_PATH & VOLTS_LOG_FILENAME & DateString & ".ip", FileMode.Append, FileAccess.Write, FileShare.Read)
Dim swVlogWriter As New StreamWriter(fsVlogStream)
Now each time I call a function SaveToVoltsLogFile(str), the str data gets saved to the file:
Friend Sub SaveToVoltsLogFile(ByVal str As String)
swVlogWriter.WriteLine(str)
swVlogWriter.Flush()
End Sub
But by opening it this way, I cannot call a sub to close it and open a new file for the next day because putting the Dims into a sub means that the file is out of scope to other subs/functions, so my Save... sub won't work! So, what I think I need is a separate sub to open the file, another sub to close it, and another to write the str data. But how do I do this and keep the file in scope to all subs?

I am creating a program to simulate a tenpin bowling scoring system, and I'm using labels with the following name structure:Player1Frame1Ball1, Player1Frame1Ball2, etc.. I have following variables also: CurrentPlayer, CurrentFrame, CurrentBallI am hoping to use these variables to specify which label I would like to check the value of (the score achieved, placed in the label).
To test my experiments I have been trying to output the score of the first ball in the current frame in a msgbox, but to no success:

Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
View 3 RepliesI have a simple in VB/ASP.NET form containing two text boxes, I am attempting to apply some validation to the first text box using JavaScript. This is the first time I have attempted this and am having some trouble.I have a label beside the text box stating an error, this labels visibility property is set to False. I wish the labels visibility to turn true if the text box is empty when the user loses focus.For this I have used the onBlur option within the tags of the text box. It then calls the JavaScript function and should set the label to Visible but it does not. I have tested to see if it is entering the function by using an alert instead and that works. The problem seems to be trying to alter the visibility property of the label.
Here is the portion of my code:
The JavaScript:
function myRegEx(frm) {
if ( boxUsername.value == "" ) {
invalidUser.visible = True;

I have a program with lots of buttons and textfields etc in my main class (I guess), in the default on called Form1.
Aaand, I want to create a class, but can someone tell me how to change the text on labels and buttons from that other class, since the labels and such exsists in the main class?
How can i change two .text values of two label objects from one class?
I mean right now for me to change the text of two seperate labels i have two create two indavidual classes for each label to rename them.
But is there a way for the class, to change the names of both labels according to the class without having to create a seperate class for each label?[code]...

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

View 3 RepliesWell 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...
