try using an interface.... IColleague
Thanks for the input Philip.
I was actualy trying to avoid implementing an interface as I was hoping to be able to just use "any old" control. But, it looks like using an interface or reflecting the controls may be the two most reasonable approachs. I'll probably whip up a little test app today and see how I like the two approaches.
Thanks again.

IMHO interfaces, reflection, virtual methods and event subscriptions are helpful in this area. And quite honestly there is nothing new compared to what we already have with C/C++.

After a night of not thinking about it I arrived at almost the same conclusion. If i want this the be in any way flexable I will probably need to use reflection.

Can't disagree with you there. Just trying to learn a new tool.
Thanks for your input.

I am looking for a .NET grid product that has the following features...
1) It works with the IDE and you modify the grid using properties.
2) It supports ADO.NET
3) It is basically a small set of files and doesn't require you to download the entire SDK
4) They have some C# samples.
5) They have a free download so I can try it out.
Surprisingly, I've downloaded 5 demos so far and none have come close to doing half of these features.
Thanks!!

Our company uses Infragistics (http://www.infragistics.com[^]) WinForms controls, and so far, we are quite happy with their quality. Infragistics also has several WebForms controls, including a grid control, but we did not explore them yet.

Hi Pal,
This is absolutely Right! I have been working on Infragistics Control library for a long time now! The libraries are available for both Windows as well as Web Applications with several controls which were not available easily before! It provides the UltraGrid control which is the Best Grid I have ever seen in my Life! It has tremendous support for customization. Trial version of it is available from the Sitespecified above.
i.e. Infragistics.com
One of the most important things is that Microsoft itself has given them a lot off support during the build! (At least that's what I learnt).
Yeah, one more thing, On purchase, they provide an excellent Service!
I think you must go for this!

Hokay Dokay....
I have an MDIParent with a controller window on the side. The controller window creates the instances of the MDIChild forms and defines the MDIParent as the parent of the children. So far so good. All works just dandy -- including managing multiple instances, etc.
Now -- the next enhancement to the app. I need to do processing on the children AFTER they have been created. What I want to do is this:
Delegate an event in my parent form to do the after-creation process.
Have my children raise the event once the form has been loaded.
The question is this: Is there a GOOD existing event I can use to accomplish this that guarantees me that only the children raising the event will trigger the event, or should I define my own event to handle it? I want to make sure that normal window process does not fire this event since what I have to do is rather intense processing!
I was thinking of reusing the CollectionChanged event since my parent is not databound there should be only the intentional firings from my children. Any suggestions ???

Hi there,
There u got one more Problem in the Forms library  . Microsoft has provided enough of Collections almost everywhere possible, but they forgot to make the MDIChildren as a Collection. Unfortunately it is an Array!
So, CollectionChanged etc. is not helpful at all! You have to go for creating your own events for managing the Pre and Post creation processing of ur Child forms.
However, i would like to mention one thing that, default event processing would be synchronous. You may look at using Application.DoEvents method or use a new Thread for performing the processing to make it asyynchronous.
hope this helps!

I've modified code to display IDE like menu items in FoldersTree(by Carlos H. Perez) context menu.
Each item is newly created menu item with a same system ID and a picture if any was. All it happens when Popup is about to be displayed. Cat't attach picture to this message... I had to do this because of standart menu items under Windows 2000.
if anybody interested, email me to aprokudin@bgs.ru.

Hi!
Postulates:
- You use VS.NET
- You add a Windows Media Player control to a C# Windows
Form.
- You need to tweak the thingy so the player toolbar(play
stop, rewindetc..) does not appear -you want only the
screen.
Solutions: HelP!!!
Thanks,

We have a service here, a telephone number (00973900717) which you can call and send songs and voice jokes to friends (as a phone call not an SMS). I need to develop the same but on a web ite or a windows application, something like:
1. Create audio files (compatible format).
2. start the application.
3. Choose the song or joke or..
4. Eter a friend number.
5. Submit the audio file.
6. Friend will receive it as a phone call
Can I do the same using C#?

Can you do shell type commands (ex. executing programs) in a web form?
Me, wrong!?! Nah, you just need to change your thinking to make me right.

Yes, using the same classes you would with a Windows Form: System.Diagnostics.Process. I (and thousands of other experienced developers) would warn you against this, however. Web servers are open to enough worms as is without providing a means to execute any command on the server. If you don't protect it well enough (and proper protection isn't as most people think), anyone could run any command on your server, such as extracting your server's SAM database (system and user accounts), copying it to a publicly accessible directory, downloading it, and running a brute-force cracker on it like l0pht crack. Then they become your computer's administrator. Much more is possible, especially in larger corporate networks. I advise against it.
Also, this does not qualify as shell programming. Shell programming works with the UI to provide and consume services to and of the UI. This is simply process execution. If you are asking if you can bring up the "Browse for Folder" dialog on the web site, you can't do it in the server context (its a blocking call and no one can close the dialog) and on the client you would need a thick client application, but then you have security to deal with from the browser. Using ActiveX in this way is tricking and using .NET embedded user controls[^] is even trickier. If this is the case, just deploy a regular application to your clients.

Here's what I'm wanting to do:
* when the user selects an item in the listview I want to change the font color, background color and add a border to the row instead of the default row highlighting.
I've read through some of the ownerdrawn examples on CP, but it's not exactly what I'm after.
Barring adding a border, here's what I have so far:
private void listView4_Click(object sender, System.EventArgs e) {
int i = listView4.SelectedItems[0].Index;
listView4.Items[i].Selected=false;
listView4.Items[i].BackColor=Color.GreenYellow;
listView4.Items[i].ForeColor=Color.Black;
}
Main problem is that the row first highlights then switches to the greenyellow color. 
I'm keen for an easy solution to this prob., but I haven't found one yet.
Cheers,
Simon

The default painting is what is causing this, so owner-drawing your ListView is exactly what you need. Even if you override ListView.OnSelectedIndexChanged (doing what your doing is not soon enough in the event chain) you still have to take care of all these color changes. To implement this form of owner-drawing, however, you'll probably have to override WndProc and having the LVN_* and NM_* notifications of Win32. You could try doing this in OnSelectedIndexChanged, but that won't give you the border you want.

There are a couple of reasons why it might not work :
- the view style must be "report" : this.View = ListView.View.Report;
- the view must be properly activated : this.Activation = ListView.Activation.(OneClick | Standard | TwoClick);
- the custom styles must be really set as used : your items must have the "UseItemStyleForSubItems" property set to true.
That said, it is not possible to add a border without really ownerdrawing the listview, ie override WndProc.
PS : the funny thing about the owner drawn capabilities of ListView is that the CustomDraw implementation is really exactly the same than the WIN32 NMCUSTOMDRAW handling (NMLVCUSTOMDRAW struct, item stages, ...).

I am writing C# application that needs to do some job with Excel 2000. I add Microsoft Excel 9.0 Object Library to the project and in code I try to create an Excel object:
private Excel.ApplicationClass ExcelApp = new Excel.ApplicationClass();
OK, object is created, but when I try to access its properties I always get an error: Old format or invalid type library!!
Does anyone have an idea what am I doing wrong?
