I've created and populated a stringbuilder for a csv file. Normally I write it directly to the response object for the user to download through the browser.However, now I want to save it to a SQL DB image field. Is there a direct way to stream it in?

I have a "For
Each
Row As
System.Data.DataRow
In
DataTable.Rows" type loop. I want to save the contents of a field to use in subsequent processing.
It looks to me like the proper way would be to use something like the following:
Dim saveCatalogWorkID As VariantType
For Each clsWTRow As System.Data.DataRow In clsWTDataTable.Rows
saveCatalogWorkID = clsWTRow.Field("CatalogWorkID")
Next clsWTRow
I've got a stringbuilder variable, that I want to return the contents of, but if it's empty I want to return "|", so is it best to use stringbuilder.tostring in the compare statement e.g
If lReturnStringBuilder.ToString = String.Empty Then
lReturnStringBuilder.Append("|")
End If

I created an application in which the user has to specify the number of rows and collumns. Once these are specified, a Table Layout Panel creates these number of cells with each cell having a button and a Text Box inside it. On the double click of a button, the user can change the background image of the button, specify the sound for it and similarly fill in the text box too. The sound specified should be played on single button click. Once done for all the cells, it would look something like this.[code]...

View 1 RepliesI've created a windows form in VB Express 2005 with lots of combo boxes and print and save buttons.I would like to be able to save the contents of the populated combo boxes, labels etc ie the whole form from the save button, preferably to excel 2003. However, would be just as happy to save it in the form format. The only code behind the save button I have so far is this, which just navigates me to the directory.

I have used the XML serialization to save a single text and a picture in a XML file.However, I am confused on how to extend the concept further.I have a second Windows Form which has a TableLayoutPanel in which each cell has a Picture Box and a TextBox. The user has the option to set the number of rows and columns himself, so I do not know about the number of pictures that have to be saved in the XML file. Further, when the user pressed the load button, the same pictures have to come back to their original pictures boxes in the TableLayout.
How can I save the contents of the TableLayout in the XML file and retrieve them in their corresponding cells?
