If the datagrid is bound to the dataset, all you would have to do is select the row, hit the delete key to mark the row for deletion.
In your code, you would have to use an SqlDataAdpater[^] to update the database from the modified dataset. This code would typically be behind a "Save Changes" button on your form with the datagrid.

hi pls help me out in inserting text into a richtextbox.
the situation is like this::
i want to insert a string say "hello" at a particular location in the rich textbox.
The particular location is given in the form of X and Y coordinates.
eg:: PutString("hello",10,20)
i write a function that passes the string and x,y coordinates.
is that possible??
x,y coordinates will represent the location of the string in richtextbox.
any ideas.. pls help!!
thnx....

Sure. In your "PutString" method, you'd have to call the RTB's GetCharIndexFromPosition method to get the character index of the point in question. Then it's just simple string manipulation, using the Insert method on the string returned by the RTB's Text property.
Dim charIndex As Integer = RTB.GetCharIndexFromPosition(point)
RTB.Text = RTB.Text.Insert(characterIndex, newText)

how to send screen resolution on serial port in VB
|
|
|
|
|
The screen solution would just be a couple of numbers. You send that as a string out the serial port just like any other string of text.
First, what does the device that your sending this information to expect? In what format does it expect this information?
Second, which version of VB?? VB6, VB.NET 2002, 2003, or 2005?

You can step into the dll from your app in the debugger, to see what the issue is

You're going to have to step into the code for the .DLL (provided you have the source code for it!) and find out what's going on in there.
With the description of the problem you gave, that's about the only thing anyone can tell you to do. You haven't said anything about the code, any exceptions you're getting, what the thing is supposed to do, ... nothing. Because of this, it's really hard to give any advice that would mean anything.

What method do you think is better when there are many threads?

Solution 1: buy a magic lamp and carefully consider how you are going to formulate each of three wishes, and polish the lamp.
Solution 2: If you have more than three wishes, be very nice all year, send a list with your wishes to Santa Claus, The North Pole, and keep you fingers crossed.
My advice is free, and you may get what you paid for.

Hi All.
My program need to kill a process, and it works well .. BUT:
When the process die, leave a taskbar dead icon that goes away by passing with mouse on it.
So my question is:
There's something like a Taskbar.resfresh() method that could make that work for me??
any other idea??
Thanks!

You can't do that. You will have to pull the icon down from the website first and store it in memory then assign it to the Form's icon property.

Not off the top of my head. Look for classes in the System.Net namespace WebRequest and WebResponse come to mind.

Like Colin said, you can't do that.
You'd have to download the icon file to your machine, put it into your project folder, then assign the filepath to the Icon property or add the icon to your app's resources and set the Icon property to that.

You know any browsers they can detect icon and display on window form.
Example IE7, Firefox...

That statemnet made no sense at all.
A web browser can NOT "detect an icon" and display it in a windows form in your application.

Hi, How can i get icon from web site to my form.
example
Me.Icon =Icon
I want to replace Icon to another icon that i want.

If the icon is displayed in your browser window, have you tried right-clicking the image and picking "Save As..."??
|
|

You give me wrong answer
?????

No, I didn't. Unless you save that icon file to your hard drive, you can NOT use it in your application. It's that simple.
