Hi there, Basically, I have an application that I would like to be able to check for updates from a webserver. Now, this application will have many files that need to remain the same such as a SQL Server database file and a few folders that the program will copy to dynamically. So, in order...

Ok so can I do that within the INSERT query method itself? Because right now I call tableAdapter.customInsertMethod(xxx,xxx,xxx,xxx) and I believe it returns the number of rows affected, because it returns 1 every time. But the VS wizard adds a select statement that I rewrote to select the...

Something cheaper? Maybe a solution I can implement myself?

Hello, I have a datagridview on my form and I'd like to prevent it from adding a row whenever the user edits the last row. I need a button that will add a new row to the datagridview.. is this possible? Thanks!

They don't.. the point it was losing content was within a separate thread, thus it was unable to access the dictionary and it would return a count of 0 when debugging. All fixed now, thanks for your help!

Hi there, I'm using a Dictionary object to store the table names for db queries that I use, and different forms/objects reference this via a property on my main form. But, after a few data reads the table name begins to return nothing, and the count of my dictionary, previously 9, is zero...

Hello, I'm looking for some sort of equivalent to PHP mysql_real_escape_string(). Basically it takes user input and makes it safe to use in queries ( ie preventing injection attacks ). Is there anything of the sort in VB.NET? What would you suggest? thanks!

Thats exactly what I am doing.. the login form is an MDI child and everything else is frozen until they login. Does the other way work better?

I figured they could reopen it, but I'd rather my application be a tad more user friendly.. there is no way to prevent them from closing just that MDI child form while allowing the MDI parent form to be closed?

But what if the form loads and the user accidentally exits the login form.. they wouldn't be able to reopen it and thus wouldn't be able to access the application.
