Below code is supposed to update a table in oracle with rows imported. But it seems to update all columns in the table with only the first column which is imported from the CSV file. I figure its the "ReadFields" property which needs to manipulated/changed.

Please can you translate the above line of C# into VB.NET?At runtime, I'm trying to update an existing GridView column, as opposed to adding new columns, just before a DataBind()
View 7 RepliesAnother noob question from me...one of these days I'll get the hang of this VB!I am importing data from an Access table that has four columns/fields. I have set up the relevant headings etc on the list view control...but I have also set up a 5th column as I want to have that representing the percentage change between columns 3 and 4 (which are numeric).
Here's my code. What I want to know, is that having confused myself with code I've written / adapted from advice given etc where do I put in a forumula to add something to a column in my list view that is a calculation based on two columns imported from the table?

I have a table with a multiple columns (two) primary key. I get an error on tableadapter.Update .How can I resolve that??
View 3 RepliesHow can i do a workaround for this? I two databases(.sdf). Database A has table A1 Database B has table A2 Table A1 is an exact duplicate of A2 minus 3 columns My dataset(.xsd) is based off of tableA2 in Database B. I can fill all my tableadapters in Database A and all info in table A1 using the dataset. My problem lies when I do TableAdapter.Update() for Table A1(Since the dataset has the 3 missing fields) it tries to update table A1 with info that isn't there and I get an error. How can I update table A1 and ignore the 3 missing columns using the single dataset? Or is TableAdapter.Update() designed to Update the Database with all columns found in the dataset ?

View 1 RepliesAttempting to run an SQL statement to UPDATE a column in a table with new data. The column being updated is defined as varchar(40) and the new data is 41 bytes (varchar(41)). I get a generic 'data will be truncated' error message, but no detail on which column caused the problem. I've attached a sample VB program to illustrate the issue. In this scenario, Company is defined as varchar(40).
My question: Can I get a more detailed error message? i.e. can I get an error message that tells me the row and column that the truncation occurs in? Often times, I may be updating hundreds or thousands of rows and only one value in one column from the source file is too large for a database cell. As a related question, does each OLEDB provider create its own error messages. i.e. will the MS SQL Server OLEDB provider potentially give different text in the error message than say the MS Jet OLEDB provider?

As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.
I am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.
