Visual Basic selected Items in Listbox are disseleceted by Messagebox; vb.net
Hi folks I have migrated from VB 6.0 to VB2002.net. I upgraded my project with the upgrade-manager. Now I find out, that the functionality of the listbox isn't the same since VB 6.0. The same code works in VB 6.0 fantastic; in VB.net not. Here is the code: Dim i As Integer i = MsgBox("Really delete the marked items ", 4) If i = 6 Then 'Yes For i = 0 To List1.ListCount - 1 If List1.Selected(i) Then 'delete dataset in the background table ..... End If Next i 'show new background table.... End If (I filled the Listbox manually with List1.AddItem "item from background table".) Anyone who can say, how to get the same functionality in vb.net , whithout having much more code Or is there anyon ...Show All
Windows Forms Black label and persistent wait cursor
Hi everyone! I have a problem with a GUI, which has a label and a panel. When executing, the label is always black and the cursor is wait cursor (until the program ends). Moreover, in the Windows XP toolbar doesn't appear the label of the running program until it ends. Could this problem be due to the fact that the gui class even has the responsibility to update the graphics of the panel Maybe it is better to delegate this task to another class Thanks Do you have code in the form load event Are you executing some type of design loop Sounds like the system is churning code that displays the label or formats the label or gets data for the label! ...Show All

SQL Server Inserting millions of rows into a table
Hi, I have a DataTable in memory and I want to write a C# code to dump the data into a SQL database. Is there a faster way of dumping millions of rows into a SQL table besides running INSERT INTO row by row Thank you, Jina If you are using .NET 2.0 then you can use the new SqlBulkCopy Class. I am not sure though if it supports inserting into older versions of SQL Server but it will work against SQL Server 2005. Else it is best to dump the rows to a file and then use BCP/BULK INSERT/OPENROWSET(BULK)/DTS/SSIS. ...Show All

Visual Basic Extract ZIP File using code
All, I'm wanting to copy a zip file from a network to the local PC (not a problem) however I also need to unzip the files within the zip file to a specified location on the users machine. Can this be done through VB code Hope you can help Cheers .NET doesnt provide Zip Functionality out of the box. You'll need to find a third party component to handle this. A simple web search will reveal many components. A common one used is http://www.sharpziplib.com/ Another option maybe to use something 7-Zip from http://www.7-zip.org/ which has a command-line interface, using ProcessStart .NET does have some compression routines - but they are not winzip file compatible.

Visual C# a dll question.
It may not be directly related to the forum, then please advise. It is a very common problem for me.

Visual Studio 2008 (Pre-release) How to use constructors or methods of data object with WCF service
I have some questions regading how to use of data object using WFC Service. For example I have an object called Student (see codes below), and property IsOver25 this is readOnly property. However, if I do not put set { ;}, it's won't compile . What I need to do here in order to get rid of set { ;} statement. Another problem is using contructors and methods of data object. Since we don't put [ServiceContract] on the data object, I could not use the override ToString() version of Student object on client side. So the question are: 1. What should I do in order to use the constructor of data object 2. What should I do in order to use the methods on data object ( will not many but somes) Regards, John dang using System; using Syste ...Show All

Visual Basic Listbox Question
Hello. A question please. I'd want to set the displaymember property of a listbox with the data of 2 fields of a table. Can I do that Thanks... You will need to concatinate the fields to do this. You can do it in your code when you're adding the items to the list or, if you're binding to data, you can do it in your query. However, concatinating strings in a SQL query can be costly in terms of performance so use caution about doing it this way. ...Show All
