Hi I have a theoritical doubt in c/c++, that at the end of some functions I am seeing a const keyword. I dont know what is the purpose behind this. for example int function(int funcpar1,int funcpar2)const; I want to know purpose of the const keyword at the end Thanks

hwnd was a window handle returned when a notification that a new window is created was recieved to my filter function cbtproc. The hook code was HCBT_CREATEWND I think sztext was properly declared May be we can not send "sendmessage(hwnd,WM_GETTEXT,(wparam)100,(lparam)sztext);" to retrieve text to all type of window.

No it was dialog box. I dont have to write program to retrive passwords, it is already written by others.I can find some here

Thanks link was highly usefull.

u r almost right, I was in my own world to be honest I had written my suggestion when nobody had presented reply to the original question, but I failed to press submit. If I was totally wrong I would not have replied. why waste our time unnecessarily on useless point. bye(this time really)

I posted before his reply. anyway i will make use of information

Hi I was using sendmesage function to a window in my DLL which is attached to other application using windows hook, mainly to get text from a control. sendmessage(hwnd,WM_GETTEXT,(wparam)100,(lparam)sztext); To my surprise sendmessage was not able to retrieve text in sztext. could the problem lies in the creator of application who has not properly written code in WM_GETTEXT case. I think he/she may not have written appropriate code to provide proper response when send message function with WM_GETTEXT is called. Am I wrong in analysing please reply if u have encountered a problem like this before thanks

I think main idea behind virtual functions is they r there only so that derived classes could make use of it. If u had written A* a = new B ; ur code would have worked fine. I have not refreshed c++ from last 8 months if I am wrong anybody cancorrect me bye.

In my program, I have installed a WH_CBT hook on a filter function. I want to monitor window creation event. Problem is I am getting more than 1 notifications when a single window is created. Example when a dialog box was created I was getting more than 1 notification (in range 3-10) I wanted only a single notification. waiting for reply Thanks -- modified at 7:19 Friday 23rd June, 2006
