View 1 RepliesThere are plenty of SELECT (...) VALUES (...) statements and Parameters phrases to go with the VALUES. Those appear unhelpful to me as I have no form fields or datagrids and will be working with all the rows in a DataTable in a DataSet. Once started, this application will run to completion, writing as few as 10000 rows or as many as 250000 rows
My Task is to write out the contents of each specified DataColumn in the DataTable, one DataColumn at a time. The insert will also include the key columns and use the datetimestamp of the records as a criterion. Nulls in the specified columns are included.
My source is a DataTable, my target for the Insert is a "tall-skinny" table in an Access database. There is a smaller DataTable that is related to the source DataTable, if I was writing from within the AccDB I would use Joins. I have created a DataRelation, but have no idea how to use it in this context..
I have tried many different SQL statements but they all fail on Select. Here are snippets of the code:
'now, instantiate the specified DataTable from among the DataTables filled above
strDDTableNm = CStr(rsDDTblNms.Fields("Table_Name").Value)
Dim dtSrcTable As DataTable

In my application,i have a gridview in which columns are created at runtime.Actually these columns are created when i am entering data in a database table.[code]where Column1,Column2,column3 may vary during runtime.i need to enter values to these columns during runtime.But i cant bind these columns because these are created during runtime.The first column "Description" will not change.It will remain constant.For each description, there will be values for each column.At last these data will be saved to the database.How to add columns in the gridview during runtime?

What tools/methods are available to build pcl stream from PDFs.We have a bunch of generated PDF files that get tied up into one big pdf.I need to generate a print job to print this with the ability to insert pcl escape sequences (to control paper feed and output bin stacking) per page. As of now we use the VB.Net printing classes, convert the PDF into a rasterized image using a third party tool to print. This does not allow us to insert PCL sequences into the print job.
So, basically, we need to process a bunch of PDFs, append them to the pcl and insert PCL commands as we go along. Is there a way to achieve this. Our application is written in VB.Net.
I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable

I have a gallery which holds a large number of thumbnail images and I want to show 6 at a time.
I have this working using the code below, but I can not get the images to display as 2 rows of 3 - it shows as 6 rows of 1.
I can get the desired result by using a datalist but that stops the pageindex function from working.
I'm sure there's an easy solution but I can't figure it out.
<asp:GridView id="GridView1" runat="server" AutoGenerateColumns="False" AllowPaging="True" PageSize="6" onpageindexchanging="PageIndexChanged" PagerSettings-Mode="NextPrevious" PagerSettings-NextPageText="Next" PagerSettings-PreviousPageText="Previous">

I fill a data table with 11 columns and 1 row.

I currently have a datagridview that is built from a datatable So lets say we have 6 columns
A B C D E G
So the users will select there data from another program and paste into the the table. So lets assume that the data that is pasted is; (the column names are automatically put in)
A B C D E G
123 456 789 101 112 134
So the table will now look like following (I remove the first row because its the same as the column name)
A B C D E G
A B C D E G
123 456 789 101 112 134
My problem is that the users can rearrange thier tables(column index) so lets say user A has the table in this format
A B D E C G
123 456 101 112 789 134
So when they paste into the program, it will look like
A B C D E G
A B D E C G
123 456 101 112 789 134
So now "C" "D" "E" are incorrect and i need to swap those columns to be the same as the column name. I'm not sure how to attack this problem.My thoughts were to paste the data as is, than see what the first row in each column equals.so if it equals "A" assign it an index 0
B 1
C 2
This seems theres too many steps and will slow down the app...
