I want to understand a situation; it's related to datatable clear().I have a code that populate a typed datatable from Excel in a separate thread using a backgroundworker. This works well, the table is filled and I can see the data. Now, I want to clear the data from table and restart the import. The operation is ten times slower than the first time. My datatable variable is declared like this:Private dt as new DataTable - not a local variableI want that all subs from class to be able to use the table, that's the reason I declared the table as private. What I want is to be able to create a new instance of dt (or clear allocated memory) - maybe this is the reason for slowdown.
This is a simple program, nothing crazy, just for a VB class. The program just a food ordering form. Each part of the order has a group box, with the type of sandwich, side, beverage, dessert you want selected via a combobox, and toppings selected with checkboxes (the code for the beverages is coded differently and giving me 0 problems, but at the instruction of the teacher who saw beverages giving conflicts with the way everything else was coded because radio buttons are used instead of checks).
I use this to delete cookies System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2") works fine I checked the folder myself it deletes all .txt files.
But here Is the problem lets say I log into hotmail, Clicked the button to Clear my cookies. And navigate to log in page again, It will navigate me straight to inbox just as if I have cookies but the folder doesn't have .txt cookies file. just (index.dat). Is this means we must restart the program to this to take effect? (Works if you restart it) If so, how can I turn off webbrowser1 for a sec and turn it back? or something like that just to make sure it takes effect without me reopening the program.
I am trying to have a DateTime variable which is in a MM/dd/yyyy HH:mm:ss format convert to dd/MM/yyyy HH:mm:ss. I am using VS2008 Pro, and when I create a var:
dim dt as datatime = datetime.now It automatticlly defaults to MM/dd/yyyyy. No matter if I convert, parse, use globalisation or anything... convert to a string, which works with dd/MM/yyyy, but the minute i move it to a DateTime var type it goes back to MM/dd/yyyy I need to use this date/time to insert into a MS SQL Database and the colume is datatime type. But also is part of the app.I do not want this to be a string, I can do that, but I do need it to be a datatime in the correct format (dd/MM/yyyy HH:mm:ss)

If you want to replace this standard messagebox, handle the DataError-expection When debugging, there is no break in the code. The messagebox just pops up without showing me exaclty where the error is located.
ok I made my self a listview with a checkbox on it. I was wondering if it was even possible to add something to my form so when I build my project and I rightclick on my list view item a menu will open saying:
delete item Clear Item
A menu (not a form) just like when you do a right click on your mouse.
way to clear textboxes in VB.Net and what is the difference between the two methods? I have also seen people be critical of folk using clear objects on their forms and i can see why but in this case, i am only learning.
On a .Net app, I got an AxDataGrid on a form. The DataSource of the grid is a RecordSet,created by parsing a comma-delimited text file.rom the UI, I add a new column with a defined size to the text file and then reload the data grid with a routine that creates a new ResultSet and binds it to the grid. Things are fine and the new column is shown.
I have been developing an async socket connection server and client program. I have been testing it, and noticed that if I connect to the server from my client and then disconnect. Upon reconnecting I am on a different port(local IP still). This is fine, however when I go to send a message, and the server trys to update all the clients, it eventually hits clients that do not exist anymore. I get the SocketException 10054, and upon connecting/disconnecting enough, it no longer works at all. My question is how do I clear out these no longer useful sockets from the server? I am doing currentsocket.Shutdown(SocketShutDown.Both); and then a currentsocket.Close(); after that. When a user disconnects.
