Hi oobimoo,
Thanks for you reply.
The C# part works fine, however, at the C++ side I can retrieve only the first character of the string ((LPCTSTR)pcds->lpData equals to "T"). I tried some other castings (string and char*) but I only get the first character.
Any ideas?
Thanks!
Eyal.

Your encoding at the c++ side is ascii. As i mentioned you must use the
System.Text.Encoding.ASCII.GetBytes(s) instead of the unicode that i use in my example.

Dear oobimoo,
Indeed, now it works. However, I'm still concerned about something: if I'm getting this correctly, the calls gch_data.Free() and gch_cds.Free() are responsible for freeing the pinned memory.
However, what if the receiving side didn't get the information before this release? Isn't it better to (somehow) release this pinned memory at the receiving side?
Consider the following chain of events:
1. Sending the message at C# application.
2. Receiving the message at the C++ application, but right before extracting the sent string:
3. Context switch at the C++ application.
4. The C# application releases the pinned memory.
5. Context switch back to the C++ application. The pinned memory is released and we can't extract the string message.
Or maybe these can't happen since SendMessage is blocking?
Thanks!

Your are welcome
From the msdn (WM_COPYDATA) :
"The receiving application should consider the data read-only. The lParam parameter is valid only during the processing of the message. The receiving application should not free the memory referenced by lParam. If the receiving application must access the data after SendMessage returns, it must copy the data into a local buffer. "
From the msdn (SendMessage) :
"The SendMessage function sends the specified message to a window or windows. It calls the window procedure for the specified window and does not return until the window procedure has processed the message. "

I am attempting to retrieve a web page through StreamReader (using HttpWebRequest and HttpWebResponse).
The issue is that the process is getting redirected to a webpage indicating that "JavaScript enabled" is not detected. Is there a parameter within the HttpWebRequest that notifies the target website that javascript is indeed enabled?
Thank you in advance.

You have to set the correct headers when sending the request, so that the server identifies the request as coming from a specific browser. The HTTP_USER_AGENT value contains the string that identifies the browser.
Despite everything, the person most likely to be fooling you next is yourself.

I just found a new search engine for dot net developers. This search engine uses Google Custom Search Engine technology to provide dramatically improved search results for software developers using VB.NET, C#, ASP.NET and other .NET technologies. It searches only the best of sites having quality dot net related content.

I personally find it very useful. Try it yourself it is a great time saver.

For general programming searches (besides the CodeProject ), try Krugle[^].

Because, and not to labour too fine a point here, IT SUCKS.
One of the reasons people like google is because it's simple and the interface is clean.
This interface, redefines suckyness to a power of 100. It's like somebody took suck at school and decided to become the Emeritus Professor of Suck. I don't care how clever the freakin' interface is - if I can't get to the information I need within a minute then you haven't helped me you steamin' pile of suckin' interface. Perhaps we could coin a new word for it - the SUCKIFACE.

Amen to that. I recall someone posting a link to the said search engine in the Soapbox, it got poor review, and, well, let's just leave it at that

It is really lame, I've tried some of the typical search strings I use in google, and cuil's search results just really bite badly.

What a steaming pile of crud this site is. It's too busy, and too complicated - it's simpler to use Google (and a lot cleaner). By your length of time on this site, I'd have to say you were spamming us.

I would stick to Google, i think guy will earn dollars if we search on his site so i would stick to google only.

Humm
Are you using a specific control to display your text?
I recently read a C# book : "Dissecting a C# application"
in this book the authors are dissecting all parts of SharpDevelop application (C# editor), they created an editor from the scratch.
You can check-it it might be helpful.
