I'm converting a process from VB 6.0 to VB .Net. The process copies a table from one database table to another database. In many cases they are not linked so a "Select * into Table2 from Table1" is not a solution. Also the source table may be a temporary global table that has a unique structure. The current process reads the source table into an ADODB recordset, obtains the columns attributes to create a new table, creates the new table, builds insert statements from the source table, and then inserts the rows into the new table. I'd like to take advantage of any .Net features that may be more efficient than that. Can anyone point me in the right Direction?

A long time a agp I settled into a listview as an indicating device. I do not use pictorial modes or graphics. Just listing and multicolumn listing.I am also a performance bug and I have written realtime monitors for monitoring cpu activity in real-time and normally rum them starting at bootime. Lately I have found that the listview throws away time. In a tight loop, the list view does not take all cpu time available and the listview is relatively slow.
Does anyone know of a control like the list views only it's faster? Multi-colored and multi-columned are musts.
I have managed to get it to write a string to a textfile if the listviews checkbox is checked but i can not get it to write a particular string if it is unchecked.
'LOOP CHECKED ITEMS
For Each lstItem As ListViewItem In Me.ListView1.CheckedItems
Next
How do i Iterate an unchecked item as the library doesn't have .UnCheckItems?
If its checked i need to add "true" to the string and if its unchecked i need to add "false" to a string that gets written to a textfile.
OK, I've been searching for hours trying to find the best way to fill a listview from a comma delimited file but have come up empty handed so far. Currently I am using code I found on the NET, which works, but it is EXTREMELY slow. As a test, I created a file with 5,000 rows, and 10 columns. The column layout is as follows:123,NAME,NAME,NAME,NAME,0.00,NAME,YEAR,NAME,1
Dim ofd As New StreamReader(".dataCardData.bct")
Try
Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser(".dataCardData.bct")
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")

The code I am currently using appears to be loading the file and somewhat simultaneously filling the listview at the same time. I feel that I should load the entire file into an array or arraylist and the send the array or arraylist to the listview. However, if this is the best way to do it, I have not been able to find any examples of how to do this.

View 12 Repliesi have a program in VB.Net 2005 and my problem is that it runs very slow. I mean, it takes some time for the Form to be displayed even if it is not doing anything in the Form_Load event. Do all programs in VB.NET 2005 act like that? my programs in VB6 would display the Form instantly.
