I need to poll the server for updated contents. So I added a META REFRESH tag to the page. But it seems that META REFRESH has memory leak issues and it crashes IE.What is the best way to poll data from server continuously? My app is quite old (partly ASP and partly asp.net). I can't invest on technologies like HTTP Push...
View 2 RepliesHow would I go about running a query in asp and storing it in an array. Then with the array go through each record without having to refresh the page every time.
For example
Sub loaddata()
Dim conn As New IfxConnection(connectionstring)
Dim results() As String
Dim i As Integer = 0
conn.ConnectionString = connectionstring
[Code] .....
The results are stored in results(i). Say I have a button that says next and everytime I want it to go to the next item in the results array. I don't want the page to refresh. How do I do that?
I have a label, let's call it LblA. I have a SqlDataSource, let's call it sds. Now, I have selected out and managed to get specific values using the select function. I want to set LblA's text to the value selected out of sds. I need this to occur every 5 (or as many as I specify really) seconds. I orignally used a timer object, however, for any of you who have used the timer object before, it likes to refresh the page, this makes it very hard to navigate off of the page; not only that, it's sloppy. Does anybody know a way to easilly update LblA's text from sds without refreshing the actual page.
I've read around and came to the conclusion that I need to use ajax, err... jQuery. However, I really don't know anything about the two except that they are both Javascript libraries? I need a simple way, you might even have to explain it to me like I'm an idiot.
I have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

2. Is there any way to get the new scrollbars of IE10 or metro style scrollbar or what not into the webbrowser like the desktop version of IE10 does in Windows 8 Consumer Preview?
3. Is there any way to allow the close window called from javascript to be detected & actually close the window in my program?
4. Is there any way to make it so when new window is called it will open a new window with my application in a new instance? stopping me now is it seems to want to open in the same window if I use the event NewWindow to cancel the event from happening but it gets script errors....is there any way to retrieve the link to what it needs to open so I can handle this properly? Or at least tell it what else to use? besides the default browser....I want it to open inside my own program & not IE.

I'm looking for an example in VB.NET of a continuously scrolling form. This would be similar to a continuous form in Access but with a major difference in that when you scroll it the whole thing moves up or down instead of the data jumping up or down to the next section. If you are not familiar with Acces, this would be a form that lists data down the form in sections, one per record, in other words, like a bunch of forms strung one after the other. When you scroll down, the record at the top gradually disappears and is replaced with a new one at the bottom.
This needs to be a form with controls, not a datagridview.Right now, I'm trying to find an example of this. I tried searching for one and couldn't find one. Does anyone know of an example of a continuoulsy scrolling multi-record form where the whole form moves in VB.NET?
i need a program that when I press a button on the form, it will display the system time continuously in a text box. I know i need a loop to do this but what I have keeps freezing my program. Heres what I have:
Sub getTime()
Dim currentTime As System.DateTime = System.DateTime.Now
Dim x As Integer = 1
[code]....
Basically wat i'm trying to do is continuously write numbers from 1 to 10000 using 1 thread & stop this using another thread. But it doesn't seem to happen.
I have pasted the code for your reference.
Imports System.Threading.Thread
Imports System.Threading
Public Class Form1
