Asp.net - Counter Variable Not Increment In .NET Code Sample?
Jan 27, 2010
I have the following code
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim counter As Integer = 0
Dim t As DataTable = DirectCast(Session("MyDataTable"), DataTable)
Dim row1 As DataRow = t.NewRow()
If (isUnique(t) And counter < 30) Then
row1("ID") = counter + 1
I have a button on a form, and I want to increment a counter an display it in a lable, while the buttion is pressed. Similiar to a numberic up down control. The reason is that I want to use a custom looking button, rather than the look of the numeric up down control.
Is there an easy way to do that while the button is being pressed? Or would it make sense to change the look of the numberic up down (I don't want UP and DOWN on the same control, though).
I can retrieve the contents of a webpage into a variable like:x = objIE.Document.body.outerHTMLBut during development (data parse), Ikeep pulling up a live site and instead just want to store some sample html in a format that can be placed in a variable. The issue is that trying to directly place a raw html sample into a variable creates errors and would require going through and escaping quotes etc.
how to add a counter variable to this array? My code always stops when it gets to an empty array. I can't figure out how to make a counter variable to make it stop.
Private Sub btnTwo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTwo.Click For Each i In PlayerArray
I am using the AJAXToolkit Accordion control and dynamically adding panes to it based on a query of the database. For example:
Jane logs in and pulls up the page with the accordion on it. In the database she has five rows in the todo_list table. So, I need to dynamically generate five panes that contain the info. from the table...but if Joe logs in he may have only three rows, and Josh may have fifteen - so I can never know how many an individual will have beforehand.
So, I need some way to dynamically name the variables (or is there another way to do this). For example, here is some pseudo-code of what I'm trying to accomplish:
Dim i as integer For each row in todo_list Dim ap + i as New AccordionPane Add some info from the row to the pane Next

I have converted this parallel extension c# code sample to VB.NET
[URL]
using the Developerfusion tool here but I am getting multiple errors that I cannot resolve with my limited C# experience.
1) After getting errors I converted System.Runtime.CompilerServices.Extension to Global.System.Runtime.CompilerServices.ExtensionAttribute which is the closest I could come up with, and I get errors on the line (26)
Return SendTaskCore(ping, userToken, Function(tcs) ping.SendAsync(address, tcs))saying that ping.SendAsync(address, timeout, tcs) does not produce a value
2) Around line 196 handler = Function(sender, e) EAPCommon.HandleCompletion(tcs, e, Function() e.Reply, Function() ping.PingCompleted -= handler)
I get an error on 'ping.PingCompleted' saying'Public Event PingCompleted(sender As Object, e As System.Net.NetworkInformation.PingCompletedEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

I recently aqquired VB 2010 Express but have limited programming experience.I am looking for sample code and/or literature which will show me how to plot a Y=f(X) curve - for example code which will plot a straight line, a parabola, etc.I need it as a template from which I can learn about how to build such a graphing program and then tailor one to my needs.
I have a vbscript that does the following but I want to do it in vb .net and was hoping someone could post some sample code to get me started. The script does the following. Monitors 2 folders specified in a config file. When a zip file is put in the one of the folders it us automatically unzipped to a working folder and then the zip file is renamed to unzipped-<zip>.zip. I am hoping someone could post a visual studio project or code that might help me get started.
Anyone knows where I can download binary search tree for VB.Net ? I'm working on a small project for my company and I'm thinking of using BST as a sorting tool.I used to do BST using C++ and I was using linked list. I'm not sure if that can be done in VB.Net but is there any other ways? any input and comments are welcome.
I'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...

I know how to genrate a serial number using GUID. How can I use it. Suppose I send a CD with the software to someone. I do not want just anyone to use it. They have to have the KEY or SN. How can I impliment it so that if you do not have the s/n / key then you will not be able to install the software.
When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.
