You seem to have missed that he is not the OP.
But, I still find his comments to be unjustified as he has nothing to do with the query by the OP or my question to the OP.

Hello!
There's no question of "better language" here. I am talking about the OP using a framework for a purpose that it isn't intended to be used.
I also asked for the reasoning behind him writing a hook with C# (there may be genuine reasons, and I am willing to help in that case). I cannot shut up and watch or help someone to do something the worst way. I am only trying to help him do it the correct way and may I politely remind you that my reply to the OP is none of your concerns?
I also think that it is OK to add a bit of criticism where and when needed.

Hi Muneeb
Yes its definitely possible with the help of delegates in C#
I came across the same situation when i needed to code for windows taskbar switching functionality.
Let the call back function you want to hook is
private static IntPtr HookCallback(
int nCode, IntPtr wParam, IntPtr lParam) {}
which would get executed when file button is clicked.
assign:-> private static LowLevelMouseProc _proc = HookCallback;
private delegate IntPtr LowLevelMouseProc(int nCode, IntPtr wParam, IntPtr lParam);
and set the hook with
private static IntPtr SetHook(LowLevelMouseProc proc)
{
using (Process curProcess = Process.GetCurrentProcess())
using (ProcessModule curModule = curProcess.MainModule)
{
return SetWindowsHookEx(WH_MOUSE_LL, proc,
GetModuleHandle(curModule.ModuleName), 0);
}
}
You may need to use documented and undocumented Winapi calls to get the classid and Filebutton name in function HookCallback
You are done!

You may want to go back and re-read the OP's requirements. He wants to catch the messages going to a particular application. Your solution is completely different, capturing only the mouse messages comming out of the mouse driver system-wide. Those mouse messages don not tell you what has been clicked, only that the mouse has moved and mouse buttons have been pressed.
Since the .NET CLR doesn't support the exports required to do true "global" hooking, targeting other applications, there is no pure C# solution to his problem. He has to use C++ get something like this to work.

You are correct in terms of stating that he needs to use C++ to catch the messages going to a specific word application as C#.net is safe programming.
In order to make the solution possible in C# we need to take indirect route that could have been direct with VC++, with the call back function private static IntPtr HookCallback(
int nCode, IntPtr wParam, IntPtr lParam)
by using MouseMessages, we can find the point where the click happened.
Then we will use WindowFromPoint(hookStruct.pt)
We can now find the class id. and pass the message further by SendMessage(hToolbar, TB_MOVEBUTTON, 2, 12); and send the hook again CallNextHookEx(_hookID, nCode, wParam, lParam). By knowing the structure of the word application, we will then find the button control id and name of it from its structure.

Dave's point is that the whole idea of using the .NET framework for writing a system-wide hook should be dropped. There can be no sane reasoning behind writing this kind of stuff in .NET. I am also in agreement with him that what you provided is not going to solve the purpose, given this context.
I seriously believe that Dave is not in need of you to explain him how stuff works. As to your argument, it is pointless and is a waste of time as you seem not to understand what we are trying to tell.

It would be better, if you utilize your time in providing solutions to other pending questions instead of wasting your valuable time on me.

This was a great help for given by saurabh
respect your knowledge!
but i have seen Rajesh or many others who are helping badly, though criticism but proper yes most of us who visit this webiste CP needy of help there are few like Rajesh,Navneet,Christian Graus,Anshuman and finally Pallini who give performance tips also ... who helps us.
please dont mind there criticism it will help you to learn other language also ..
Rule:
More you involve here more help you get
so keep asking good question !!!!!!!!!!!!!!!!

Dear All,
I am using FileStream Class to read from pdf file and then set the DocumentStream of Web Browser to that FileStream object, but it seems web browser control doesent work so.
FileStream fs=new FileStream(filePath,FileMode.Open,FileAccess.Read);
webVr.DocumentStream=fs;
This shows a very missing things in web browser control.
basically i am using stream, that is bz i am getting my pdf file from another server.
can i show pdf files using WebBrowser Control?
i have got a reference which i can Ipersist Interface, but i didnt find any example of this interface.
i would appreciate to have an example of this interface "IPersist"

You don't need to do that at all. Just Navigate to filePath

Hi Abdul
There are two options for you.
1) File should be in the webserver location in the server, be in wwwroot folder of IIS or in any apache webserver.
eg. C:\inetpub\wwwroot\pdf\a.pdf
You can then write a c# client code
if (browser == "Firefox" || browser == "firefox")
System.Diagnostics.Process.Start("firefox.exe", urlname);
else
System.Diagnostics.Process.Start("iexplore.exe", urlname);
where urlname = "http://10.1.1.23/pdf/a.pdf" coming from an xml file.
2) you may download the file from server to your machine through the below webservice code.
// name contains path of pdf file in the server
System.IO.FileInfo fInfo = new System.IO.FileInfo(name);
long numBytes = fInfo.Length;
System.IO.FileStream fStream = new System.IO.FileStream(name, System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.BinaryReader br = new System.IO.BinaryReader(fStream);
// convert the file to a byte array
byte[] data = br.ReadBytes((int)numBytes);
br.Close();
fStream.Close();
fStream.Dispose();
// return pdf if we made it this far
return data;
and show it in the browser by the below code
if (browser == "Firefox" || browser == "firefox")
System.Diagnostics.Process.Start("firefox.exe", localpath);
else
System.Diagnostics.Process.Start("iexplore.exe", localpath);
where localpath="c:\a.pdf" coming from xml file

Hi Experts
I am Working With C#.Net in 2005.I Have a text File i read it to show in
Rich Text Box. After That I Want To Run Find Word In side The Rich Text Box and
Find Word Color is Dark(Highlight the Find Text )
Then How We Can Do Find and High light Operation on Rich text Box.
Thank u
Dinesh

You can use the RichTextBox.Find(string) method. That gives you the first instance of the string you pass it as a parameter (-1 otherwise). That's the SelectionStart. SelectionLength is fairly simple to calculate - just add the phrase's Length to SelectionStart. Then you simply have to change the SelectionFont property of the RichTextBox
