View 2 RepliesI want to programmatically set the focus to the last row (bottommost, its only one column wide) in the DataGridView control for Visual Basic. How can I do so?
So far, I have tried DGV.Rows.GetLastRow(DataGridViewElementStates.Selected)
without success, though I did not expect that to work. It absolutely must select that last cell. Otherwise, the application is nearly impossible to use!
Here is a screenshot of what I am making with this: [URL]..The "Paste Clipboard Contents" button only pastes into the selected cell, though I guess I could find a workaround.
how to sort the group of files in the directory using Hashtable by values?
i'll have more than 500 no of files in the below format:
prod_orders_XXX_<TimeStamp>.dat
XXX = symbol of the product and the length may varies.
<TimeStamp> = date and time
Multiple files for the same XXX are possible with different time stamps.
Here are some examples:
prod_orders_abc_20122001083000.dat
prod_orders_abc_20122001083111.dat
prod_orders_xyz_20122001093157.dat

I have posted a similar question before but this time i need this specificly using Hashtable.

View 1 RepliesIn a label box, I want to list a couple of websites, email address along with some text. How do I go about it?
Potential uses- As a Help > About dialog box where websites, email of the author can be listed.
To make things as easy as possible for the user, and encourage visiting of the mentioned websites.
Simple text will be ignored, while standard blue color, underlined text with hand mouse-cursor will need no thinking on user's part.
