 How to Extract information stored in the main part of any Message box window after it displays on Desktop?
I want to retreive all the arguments send to Message box. The Message box is owned by a different application.

No matter who owns the messgae box. After something is displayed on the screen, it is no more available as text it will be bitmap. You will need to use OCR. I dont know if there is an alternative. I dont know if GetWindowText() will work. But you will need the handle of that window still.

I guess this would work only to catch its caption.

Nope, I'm in the middle of some process here, so I just put the question further there , If it worries you, leave it. I'll look about it in MSDN later. No problem!

Actually By Design GetWindowText Brings the Caption of the Remote Window, remember by Design.though interally it make call to the WM_GETTEXT!

Yup Alok, that's what I knew, it would internally use GETTEXT, but why does this get supressed when its called by GetWindowText? I tried to take the text off a notepad, but I failed there. Actually I got the handle of notepad's client window from spy ++ and tried GetWindowText, but didn't work. so you mean, here sending GETTEXT would work??

Do the following
1. if u dont have the window(messsagebox) get it using FindWindow or some other API
2. GetNextWindow (pass GW_CHILD) as the flag to find the window.
I donno in which order the windows has placed in teh message box. so iterate till end.
3. Use GetWindowText by passing the find result.
this is applicable if the message box is created using normal MessageBox API.

I feel it is very difficult to solve this problem. But I believe there is a solution for all problems. So here is a spark:
We can manually copy the entire text and caption form a message box using Ctrl+C (am not sure, will it work for all the message boxes).
Check the link :
http://secretgeek.net/msgbox_copy.asp
http://weblogs.asp.net/chuckop/archive/2004/04/08/110153.aspx
So my idea is:
What about simulating the Ctrl + C and take the text from clipboard?
It is only a spark

I don't know if it is possible to save a wave file with different frequency (Fc), so I think that there is only a solution: convert the files to have got a single Fc.
To do this choose the highest Fc, and create more samples in the other file using an interpolator (ex. linear interpolation).
Then you can append the files.
Do not choose the lower Fc to do this, because the file with the highest Fc it is not simple to be undersampled: see aliasing problem!
hope that helps

hi again 
I saw in some code such thing :
(it was a mathematical formula parser)
try
{
...
}
catch(CException1 pError)
{
...
}
catch(CException2 pError)
{
...
}
catch(CException3 pError)
{
...
}catch(CException4 pError)
{
...
}
catch(CException5 pError)
{
...
}
catch(CException6 pError)
{
...
}
I have question : Is not it uncomfortable to write so many catches ? when all theses exceptions are some what related, could not we unite them under some CMainException class and catch only one exception ?
this code is from this article :
http://www.codeproject.com/cpp/VisualCalc.asp
From the Using the Code section
But the article is verry coool ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Catch(...)
and then
GetLastError()
|
|
|
|
|
GetLastError will not help u in all cases.
it applicable if only if the library set the relevant errors
u may have to design ur own class if the exception is not provded by windows or the library u are using. if it is a generic one, then the code will be very less.
there are centralized and decentralized error handling strategy. select one which suits for u. if u r trying to reduce code, go for centralized one. but the common routine or class will be bulky because of this

you can't get any error code or string using GetLastError if the Exception throwed is Custom!, GetLastError is Window specific api!

In general catch(...) is bad form. There are exceptions such as when you do a catch all, perform some clean up and then re-throw, for example. A general rule of thumb with exception handling is that you should only catch what you expect to be thrown; a catch all violates this principle.
