May 14, 2010
how to implement a counter in label which decrements every time page is loaded in asp.net(vb)? It would be better if that counter value is accessed from and updated into database..
I've tried this on buttonclick but the value is reset automatically to intial value everytime as the button is insert and page is reloaded
Protected Sub InsertButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim entries As Label = FindControl("label1")
entries.Text = entries.Text - 1
End Sub

I have a label called lblMessage. The data of the message is saved in a SQL Server 2005 DB. In my table i have a message ID and then 4 rows with my message ID. Message 1, Message 2, Message 3 and Message 4.I want my lblMessage to go through a loop every time the user refresh his browser, so that when he refresh it once the next message will be Message 2 and so on and so on.How would i do this in VB.NET or C#?

The progressbar runs perfectly, but the lbImagesScanned.Text isn't updated until all the scans are completed.

I'm currently writing a countdown timer on vb 2005, with the following characteristics: When I press a button and the timer is running, it adds time to the counter, for example, if the time is 2:30 and I press a button, and the period to add is 1:10, the new time would be 4:40. The window is always on top of every other window, and is active even though it doesn't have focus. When the time's up and i press a key, in this case Esc, the application closes, otherwise, it just continues. [Code]

I've got a project that generates a sql query and returns the results. I want to place a time/counter on the form that shows how long it takes to return the query from the server. Basically to count up in seconds from 0 while that sub is executing. Would threading be the best way to do this or is there another way that I'm missing?

We have a project that needs to gather survey data. On one particular page of the website, there are 21 questions each with a scale of 1-5 where the user selects one radio button for each question in the table. The survey is being coded in VB.NET. The data submits to an SQL database. All the radio buttons are similarly named, so only the number changes for the question [Code]

I'm working on a VB.Net windows application.In the top half of the form application, I have a vendor number with a "GO" button and in the bottom half I have a list of tab pages. We have built the application to only go to the database and display data when the tab page is selected by the user. If I'm in one of the tab pages, and I change the vendor number and click the GO button, the data on the current tab page goes blank (it does not refresh). I have been told that I have to find a way of programmatically clicking on the tab page's tab a second time. How do I do that? I've tried using _Selected event, _Selecting event, _Click event. I've even tried to do a .Focus() on the tab page itself. Nothing seems to work to reload the new data without clicking off of the tab and back onto it manually.

I have a webbrowser control and the following code is in a for next loop. If I use wba = New WebBrowser the code works in the background and I don't see the loaded pages in the webbrowser control. My question is how can I see the results in webbrowser component with wba=New WebBrowser ?
wba = New WebBrowser
AddHandler wba.DocumentCompleted, AddressOf wb_DocumentCompleted
TheLoginUrl = Items(2) & "/test.php"
wba.Navigate(New Uri(TheLoginUrl))
results.Text &= "Login to: " & Items(2) & vbNewLine

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).

I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?

I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable.In ASP it was easy with the Timer object, but in .net I can't find anything on Google.

I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.

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?

I have a content page which contains an UpdatePanel and has a combobox. When the combobox value is changed I want to change a label in my Master page. So, the main problem for me is that I don't want to make a full postback with every combobox value changing. Is there some trick to overcome full postback?
