You should be calling methods on your Person class, which then call methods in your data layer to insert, update or delete your data.

Have a global integer available to all events set as 0.
In Class:
int x = 0;
In Button Click Event:
if (x == 0)<br />
{<br />
x += 1;<br />
}<br />
else<br />
{<br />
return;<br />
}

Use a flag (as member variable of your form). On Form initialization set the flag (say alreadyClicked) to false. Then in the button click event handler, first check the flag, if it is false set it to true and, finally, do whatever is needed in the handler (on the other hand, if it is true simply return).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

well if u want to restrict the functionality then why dont u disable the button rather than popping a message and then restricting its function
you can do it by adding this to the click event
button1.Enabled = false;
but you'll need to have some mechanism to enable it again once its disabled. if this is in your req. offcourse

But same code is working fine when using without Master page reference.

I'm working on a TextBox control that allows fields (like MS Office's mail merge feature). I want the editor to treat the field as though it was a single character. The user shouldn't be able to delete part of the field or select only part of the field.
For example, a line might look like: «Image» shot on «Date» at «Resolution»
where «Image» «Date» «Resolution» are all fields.
(above ? in a diamond are actually the same double angle brackets MS uses in Word).
My control inherits from TextBox. I've overloaded OnKeyDown & OnKeyPress so that if the user backspaces it deletes the whole field. If they move left or right, it skips past the entire field. I've also overloaded OnMouseUp so if they select part of the field with the mouse, it increases the selection to select all of the field. This all seems to work.
My problem is if the user holds shift and left, I can't get the field selected and put the cursor to the left of the selection. Similarly if they select by dragging the mouse right to left, the cursor is on the right side.
A snippet of the OnMouseUp code follows:
int SelectionEnd = SelectionLength + SelectionStart;
for (int i = SelectionStart; i >= 0; i--)
{
if (Text[i] == FieldEnd)
break;
if (Text[i] == FieldStart)
{
Select(i, SelectionEnd - i);
}
}
I assume I can't do what I want with just Select(start,len) or SelectionStart and SelectionLength. Any help will be much appreciated!

If you're trying to select right to left the following should work:
textBox.Select(selectionStart + selectionLength, -selectionLegnth);
You'll need to determine whether the user was going right to left using combinations of KeyDown, KeyUp (examine selectionLength) and MouseDown, MouseUp (examine cursor position).
Good Luck.

Thanks for the suggestion, but it still leaves the cursor at the right of the selection.

|
|

Sorry, What's the base class your TextBox control inherits from?
|
|
|
|
|
You're right. The suggestion works for a class derived from RichTextBox not from System.Windows.Forms.TextBox.

What is video.ocx ? If you want to play videos in your app, import the windows media player control.

I experimented with windows media player control. For playing videos from files its really easy to use. but my problem is that i want to play a live video coming from a remote machine on the LAN. I'm using UDP for the streaming of video from the remote machine.
So duing my search I reached the conclusion that DirectShow is the thing for me. So if you have used Directshow, can u tell me how i can pick a live stream and use it to show video?

You can't remove items from an array. You may want to use a something like a List object that lets you add and remove items. Maybe you can give us more detail on what you're doing.

private static byte[] RemoveFrom(byte[] source, int startpos, int length)
{
byte[] oldi = new byte[startpos];
byte[] orqa = new byte[source.Length-(startpos+length)];
Array.Copy(source, 0, oldi, 0, startpos);
Array.Copy(source, startpos + length, orqa, 0, source.Length - (startpos + length));
byte[] res = oldi.Concat(orqa).ToArray();
return res;

When you say 'help me', did you forget to say something more specific about what you're trying to do, or were you hoping for someone to tell you exactly what to do ?
