i don't know the combobox string like this"001 littlefinger" is what you want.if so you can do :
foreach(datarow dr in ds.tables["customers "].Rows){
this.comboboxname.items.add(dr[0].tostring() + dr[1].tostring());
}
|
|
|
|
|
Just seperate columns with space
<br />
this.comboboxname.items.add(dr[0].tostring() + " " + dr[1].tostring());

Search the articles here, there are plenty of custom controls you can use: Search for combobox and multicolumn[^]

I am fairly new to .NET and C#, and on a very steep learning curve, so if my terminology is a bit off I apologise.
My perception is that click events on a button contained within a toolbar are processed differently to click events on a button clicked on the form body. In the case of a form body button the control with focus, when the button is clicked, receives messages via it's delegate event methods. However, in the case of a toolbar button being clicked, the control with focus receives no messages as far as I can tell - not even a LostFocus message.
Could someone tell me where this is documented - I don't care that it is different, but I do care about the dearth of information on this sort of issue.
Regards PhilD
BTW thanks to all those who contribute to this site, I hope I can reciprocate in the not too distant future.

There are many tutorials available to you both on Code Project and elsewhere on the internet.
From the Arab American University portal, [^] you can download these e-books and read at your leisure. The site is a bit slow.
For tips you can download (ASP.net and Winforms) you can visit http://www.syncfusion.com[^]

Thanks Richard - not sure what your expectations are but I just dl'd a weeks reading in a few minutes from AAU

Oh I also believe that the ControlCollection Find method on a form does not find toolstrip controls, but it does find controls imbedded in other things like TabPages- the searchallchildren argument is of course set to true.

I've never used a ToolBar object (I usually go through the hassle of making my own toolbars), but, after glancing at MSDN's documentation, it seems it would be pretty easy. The ToolBar has the ButtonClick event, and the ToolBarButtonClickEventArgs object tells you the index of the button clicked (with which to use switch). That seems to me like plenty of information to be able to act on clicking the different buttons.

Daniel,
The issue is not the processing of the click event on the button itself, but what events the control with focus experiences when the toolbar button is clicked. With form body buttons the control with focus can detect that it is losing focus etc - I can't recall the exact sequence but it's something like Leave, Validating, Validated, LostFocus - however with toolbar buttons the control with focus seems to experience no events whatsoever, when such a button is clicked.

Hi..
can anyone help me figure out the algorithm for the following problem:
Consider a = {a , a , a ,...., a } //random values within set a
----------i----0--1---2-----n //these are the sub values
also
b = {b , b , b ,...., b } //random values's within set b
-i----0---1---2------n //these are the sub values
And
S = a + b
-i----i----i //these are the sub values
Find an algorithm O(n), that can return the n largest number(s) using c#..
Thanx soo much in advance..

Get all Si results, sort array (ascending) and get your n results at the end of array.

This is a school assignment if I ever saw one.

Yes, it's very simple solution, but this solution is "fast-realizable".
If you find O(n) solution please tell me. I'm so intrested...
Best regards, Alexey.

Isn't Radix sort O(n)?
Looking at what's given I half suspect the data has restrictions that would make a trivial solution possible, but I don't want to do this guy's homework for him.

Hey man, thanx 4 ur reply.. i wanted 2 ask you though, what u meant was consider a and b as arrays of values, then add them to a new array S containg the values of a and b, and then sorting the array, and then fetching the largest n #'s? But bro, isn't that more costy than O(n)?!?
Waiting 4 ur reply mate..
Thanx Again,
Elie

Is it possible to implement chat rooms that can use by the asp.net and the window form. Can this chat room use xml web services to connect each other? or got any suggestioon? Thank you thank you

Well... I have a Control Inherited from Combobox. The purpose is fill the items in the combo with the content of a Table... the problem is when I am filling the combo, even when it is not Visible, he Drops down at the load of the form... if there's only one combo, no problem... but when there are many combos, the load of the form results in an horrible intermitance while filling combo's, someone have any idea???
Ah... when i reassign the SelectedIndex or SelectedItem properties, the combo also Dropps down...
Bye

I'm trying to make my own screen-capture program. My theory is to take bitmap screenshots as fast as possible, and feed them into an AVI. I've read some articles on taking screenshots, and it looks like it's a tossup between using .Net (with Graphics.CopyFromScreen()) and using API calls (gdi32.dll and user32.dll).
I just finished the former, and it's slow. I can't get it to take bitmaps faster than about three per second (my goal is at most 30 per second).
My question is this:
Before I spend time on altering all my code, will using API calls make it take screenshots any faster? If not, I won't waste my time.

Three per second sounds very slow, I'd expect the API to do it faster than that.

Alrighty, I'll give it a try. Thanks!

It did go a little faster using the API calls (judging by informal indications, somewhere slightly more than 30 per second). Thanks! This site rocks!
