I created an application in vb.net I have a user control having datagridview and some other controls. Grid rows is not fixed and so size is calculated dynamically so that grid do not have scroll bars . when I run my application on different desktops it works perfectly. But when I open the application on laptop for same resolution it shows the scroll bar. Do I need to write different code for laptop and desktop for user control size or any property which need to be set to check it. one more thing Grid is set dock and user control is also set as dock in a panel So I do not wrote about anchor property.

View 1 RepliesSome of u already know I'm making a 'virtual desktop'- thing.Only one problem. When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.

My program reads a 3rd party data text file and I give the user the ability to add a row. The problem I am having is one users text file contains an extra tab at the end of each datarow thereby creating an extra column when i view it in DataGridView it gets labled "NoName"
Moving foward I get the following error upon trying to isnert a new datarow. The INSERT INTO statement contains the following unknown field name: 'NoName'. Make sure you have typed the name correctly, and try the operation again.

Using OLE and Jet, you may receive errors when saving system dates and times to databases in different regions.Consider what happens when saving dates and times returned using the Now() function in Canada or the US: the date string "#2010/02/03 08:59 AM#" will save fine. If using 24 hour time, the string "#2010/02/03 08:59#" will also save fine.
If you change your system region to Spanish (Peru) or Spanish (Mexico), the ante meridiem changes from "AM" to "a.m." (or "p.m."). The date string becomes: "#2010/02/03 08:59 a.m.#"Note that this will NOT save correctly to the database and throw a System.Data.OleDb.OleDbException. The workaround we use is: Public Function clean_date(ByVal strDate As String) As String Dim str_buffer As String
