ced',
off topic but, did you receive my mail ?
(sorry if i am a bit insistant about that, but i'm desperate about it[^], and i'm sure you could be of any useful help  )
|
|
|
|
|
Err, no, I didn't get your mail.
But I answered to your question. I'm not sure at all if this is the correct answer though...
|
|
|
|
|
thank you.
i answered consequently.
i'd be glad to share this with you...
(actually, you'd save me my nerves ! lol)

Yes Dear ,
It is a linker error.
|
|
|
|
|
Then you got a linker problem...
Sorry but if you don't give more information, it's the only answer I can give. What is the exact error message ? And give as much relevant info as possible.
|
|
|
|
|
1. DON'T SHOUT
2. explain clearly what you wnat to do
3. explain clearly what problem(s) you encounter
4. ask for specific questions, instead of hoping someone will do the job for you...

To refresh the views use
CDocument::UpdateAllView(NULL)
that force an update of the CView
and then use CView::OnUpdate
to initialize the view assuming that the document is changed so everything(variables) must be reloaded from the document.
Elseway, a simple way is to study the constructor of the CView, probally you are not considering that the first CView has an initialization that you forgot in the other Views.
Have a nice code day

Hi,
i written a console application from VC++, program is to generate a binary tree.
program will take a directory as a input and generate a binary tree of words..
problem is if i give a small directory with 5 to 10 files program generates the binary tree properly if i select a big folder it gives below error can anyone help with this..???
=====================================================
This instruction at "0X77f8910e" referenced memory at "0xc7c7cf0".The memory could not be "read".
Click OK to terminate the program
Click on cancel to debug the program
OK CANCEL

You may have to check those size indicators / holders in your code as array boundary or something.

As you've seen, "<" and ">" are gone. Would you just send me the cpp file to (sautiller @ yahoo . com)? I will check your code.

Did you try to press the cancel button to see where it crashes ?
It is VERY helpfull for us to know where (man, I don't want to go through all this code to find the problem)
|
|
|
|
|
i get the error message soon after run (Ctrl + F5 )
it does not produce any output
|
|
|
|
|
Start your debugger and tell us exactly at which line of code it crashes (press F5 instead of Ctrl + F5).
* me  *
|
|
|
|
|
hope this will help u.
after F5

You are kiding aren't you ?? I simply ask you to tell us where the debugger stops when it crashes. At which line of code in your program excactly (there is a yellow arrow next to your code) ?
I think your eally need to learn a little bit to work with your debugger. I cannot imagine my life without one  . No seriously, try to play a little bit with your debugger to see how to use it. It will be a very good friend that will help you in many many situations.

77F8910E cmp dword ptr [edx+14h],0
after F5 arrow stopes here ....
i have just started learning VC++ so i have very less idea abt Debuggers..
|
|
|
|
|
Ok, so it is not directly in your code probably.
Now, put a breakpoint at the very begining of your program (by going on the line and pressing F9). Then ,put several breakpoints in relevant points in your program. Each time you press F5, the programm will advance to the next bbreakpoint. And there, you can watch to your variables and things like that. Try to play with it and understand how it works, it is really usefull and it will really help you a lot !

Thanks for the inforamtion.
it will help me a lot....
i will try to do that..
