View 10 RepliesWhenever I build my VB.Net project, the Assembly version does not automatically update as it is supposed to with the * in the third box in the Assembly Information. The only way I have found to (sometimes - it doesn't always work) get the version number to update is to Clean the Project, remove the *, Rebuild, reClean, put the * back in, and Rebuild again. What could be causing this issue to happen?
I should note that my coworker reports no such issue on his machine when Building the same Project; also, I must admit to some confusion on my part as to how this behavior is even possible, given that the error persists even if I remove every possible intermediate file I can think of that could possibly even be carrying the old version number, so how does it even know the old version number?

i have a folder called xulrunner that needs to be initialized - i originaly had the folder under c:\ and used the following code to initialize it.

RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)

How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
how can i return the number of records processed from an sql procedure whether it is a select or update/insert query and how can i receive it in the calling method in vb .net.
