Clearing All Items From A List Viewer?
Nov 25, 2011I have a list viewer set up in one of my forms which contains data inside it which is filled in from a database. When I want to clear the list viewer, it clears all values in the list viewer except for the first row. Now, if I close out the form and re-open it, the list viewer is officially cleared.
The code I am using is: lsvDocuments.Items.Clear
Is there another way I can clear the list viewer completely without having to close the form and re-open it?

View 15 RepliesVS 2005 "refresh" The Sql Update Commands After Every Tableadapter.update?
Jun 15, 2012Environment = VB.NET 2005 & Pervasive SQL 9.5 ADO.NET In a simplified example, I have single database table (customers) with the columns "customer_code_PK" and "customer_name" This table is presented in VB.NET 2005 as a single form datagrid (bindingsource/dataset). In this example, the database table is populated with the following data
customer_code_PK customer_name
SHELLShell Oil
BPBritish Petrolium
MOBMobile
In very simplified terms, code does the following;
sub on form load
fill dataset with database records (select * from customers)
[code]....
The datagridview loads the records correctly.Here is the sequence of operations that produces the bizzar behaviour.In the editable datagrid;
1.remove the row with PK = MOB -> save_button -> Database correctly updates
2.add a new row with PK = KFC -> save_button -> Database correctly updates
3.remove row with PK = SHELL -> save_button -> Database exception occurs
On this last command, the row SHELL is INSERTED!!, not removed.However, If I change ths save_button routine to this
save_button
call generate_custom_updateinsertdeletecommands
bindingsource endedit
[code]....
It works correctly !Is it correct that you would need to "refresh" the sql update commands after every tableadapter.update?

View 1 RepliesRefresh Datagrid After An Update?
Jul 30, 2009I have a main form with player information (it's a sports application). To add or edit a player the user presses a button which opens another form. They either add or edit from this point. When they click 'OK', it saves the data to the database table then goes back to the main form. The amended or new info doesn't appear. If they close the application, then reopen, the new info appears in the datagrid now.
how I can get the datagrid to refresh once I press 'OK' on the input form?

View 1 RepliesGDI+: Update Or Refresh Only Certain Parts Of The Screen ?
Jan 30, 2010I'm making a game using vb.net and GDI+. I've been encountering frame rate problems and one solution that was suggested to me was to only refresh certain parts of the screen. I was also told one way to make this happen was to use rectangle or region structures and since I already have these as hitboxes it seems like a perfect way to efficiently reduce the drop in frame rate.
The only problem is that I have no idea how this would work and so far my google searches have been fruitless. Yet again I turn to this very helpful forum, can anyone help me? By the way I've set doublebuffered to true on my form to get rid of the annoying flicker.
Questions. How do I update or refresh only certain parts of the screen?
I'm using a timer set to tick every millisecond to run everything and it refreshes the screen every 2 milliseconds simply using me.invalidate; each time it ticks things move a little bit and stuff happens that triggers other events etc. The problem is that when the framerate supposedly "drops" things start to change. "Bullets" and projectiles appear to travel many times faster and much less smoothly than they do when there a less objects moving on the screen, it's almost as if the timer runs faster... What's the reason for this? Is there a way I can change this? I remember hearing about a "stopwatch" or something that someone used in their game that was more consistent or something.
Also I'm aware that vb.net with GDI+ isn't exactly the best language to make a video game in but it's for a school project and I have no choice in the matter.
