View 1 Repliestrying to understand DataGridView. I can sum columns with no problems and place the result in a textbox. My problem is multipling two column rows and saving it. I receive the following error when I go to save it. "Column mapping from source column failed because the data column is a computed column.

I'm trying to run a simple select statement using an ADO recordset. But the resulting recordset returns 3 times the number of rows. For example the query should return 20 rows but is repeating 2 more times and returning 60 rows. When I run the query in Oracle it returns 20 rows.
Here's the code.
sSql = "Select * from Sector"
cnnOracle.Open("DRIVER={Microsoft ODBC for Oracle};SERVER=REPDATA.world;UID=auser;PWD=auser;")

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

View 1 RepliesI have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):
'Sub table 1

xx|C201 |02300877 |Toshiba |....

p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:

I have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.

I have an application in VB6 that joins 3 tables together to create 1 record set and I am able to use the move next and move previous methods to navigate through the record set.
I am having trouble creating this same scenario in vb.net with a data set. Do I have to create each table individually and then link them together somehow or can I join them all together in a query before I fill the data set?
I have a continious Form which opens and shows records of people with whatever criteria the user had chosen the screen before. When the form opens it checks which button was pressed and then changes the recordsource of the continious form.
