View 5 RepliesI am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.

txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

View 2 RepliesHow 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
