Everyone else might shoot me for this...
But, it's "kind of" possible. Not every application will support this and this is by no means(!!) a supportable solution, so don't even think of selling this to a customer or doing a company-wide deployment with it.
You have to launch the application you want to "host" first, then wait for it to create it's parent window. Once created, you have to use the Win32 API functions FindWindow, FindWindowEx, or GetWindow to get the window handle of the main form of the target application. Once you have that, you can call the API function SetParent[^] and the window handle of YOUR host window to re-parent the application window into your own form window. If you want to move that hosted window around in your form, you'll have to call the API functions, like SetWindowPos, to move it around and resize it.
KEEP IN MIND THAT THIS IS NOT A SUPPORTABLE SOLUTION!! IF YOU USE IT AND HAVE A PROBLEM, WE'LL DENY WE EVER TOLD YOU ABOUT IT!

Thanks for your response. It's nice to get a response that that doesn't assume I'm an idiot. Seriously, was all the sarcasm necessary? I don't feel it's appropriate to belittle someone when they have a valid question. Of course I left out the details of viewing a pdf (I knew it was due to a COM component), but that doesn't mean I didn't know the details.
But thanks, Dave Kreskowiak. I will use your suggestion... and don't worry, this is just for my own computer.

Most people don't know about this little trick. Hell, I didn't know about until about 3 months ago. I've found it has limited uses, such as, what happens when the user quits the application? Test your code thoughly through every possible action.
The number of quality questions comming from people that "have a clue" is pretty low. I'd say the number of questions that we get from script kiddies, newbies, and wannabes, trying to do something WAY beyond their skills/understanding of Windows, is about 15x that of people who actually have any kind of clue about how Windows works. Next time, I'd recommend differentiating yourself from "the crowd" by putting a little blurb in about your experience and what you think you have to do to get something to work.

Good advice, thanks.
As far as your suggestion, SetParent works great for making a window a child of another window of the same application (for example, you can parent a notepad window within another notepad window), but it appears that cross-application parenting doesn't work with this method. Thanks for your suggestion though, I really appreciate it.
Any other ideas out there, supportable or not?

Like I said, it's of limited usefulness and doesn't work for all windows/applciations. But, it's the only solution out there. The only other way to do it is if the application you want to "host" has a COM component you can use.

I don't really think that someone tried to belittle you, you only got replies to the question that you asked. Perhaps the replies were way below your knowledge level, but not below the level that you showed in the question. Judging only from your original question, you seemed rather clueless about components and how applications work.
Also the comment about not recieving a good answer to your previous post did make you look like someone who asks things that is impossible, but not being content with the answer that it's impossible asks the same question over and over.

Agreed. In the future I will try to explain myself further in detail. I posted in haste earlier, hoping for a quick answer. I was offended by the Grand Canyon remark, and I still fail to see the benefit one would receive from such a statement. But as I said, next time I'll be more thorough.

Again, haste is to blame. I shouldn't have used "good" and I meant to thank the persons who initially responded. I started this new thread because my old one had been buried under all the new posts. I did not intend to give the impression of asking over and over. I am happy with the responses from this post, aside from the Grand Canyon remark.
Although, I'll admit it is a rather funny analogy.

As Dave's said the large majority of new posters are relatively clueless, and that fair or not anyone new to the board tends to be percieved that way until they demonstrate otherwise. I'd no idea Dave's solution existed, and your pdf example using a technology that wasn't generalizable made you appear less skilled.

I need find out how to create a virtual partition in C# (or if it's impossible, in C++). So WinXP should think there is one more partition on my hard disk, or that there is another hdd connected or smth. I need to be able to load the actual partition the same way daemon tools load the iso images, from a file...
How do i do that? Any clues?
Thank you.

I think you have to create a device driver for that. The .NET Framework cannot be used to create device drivers.
|
|
|
|
|
Then how do you create a device driver? For instance in C++ or C?

First you'll have to download the DDK from Microsoft.
Included are samples (in C++) on how to create drivers.

I don't know this, you should try searching Google for a device driver tutorial.
The C# forum isn't a place where you can get answers for this.

I need to interact with another application on my desktop .I'll have it running and if possible I want to force its menu to popup , then click one of its menuItems (like open , or save) ...after I do this the other application should bring up a child window that I need to copy its content ...
I don't want you to give me code rather just pointers on how to deal with this ...I know it's a lot of work but for me it's worth it .
Thanks guys.

Well, you *could* send Win32 messages to the application (like WM_MOUSEDOWN at the location of the menu, etc). You could also send keys to the other application via SendKeys or via Win32 SendMessage that corresponded to a shortcut key for the application, perhaps CTRL+S for save, etc. But all these things are hacks and rely on the current functionality of the application to work. The next version of the application could easily break your hack.

Thanks guys...I'll try these ideas..

you can also try macros

There are lots of articles on this site and around the web that demonstrate how to use sockets or .NET remoting to communicate across process and across machine boundaries. Have you tried searching?

It will be very greatful if u suggest me one for my query. As of now I have got for connection sending and receiving data. but now I want the path of network while sending data.

Wrong protocol or connection state for the requested transaction or request
What should i do to connect to server?

Have you read this article[^]? It talks about how to make a client and server communicate via sockets.
If you need help with a specific problem, be more specific.
