Haven't you a debugger, have you?
What are result of you inspection using the debugger?
What is the offending line, is it m_buffer=new char[dwNum];?
If the answer is Yes, then what is dwNum value?

You have got WAAAAAY more patience than me.

Maybe patience it is context dependent. Anyway your reply to former Hakan D (now Mr. Surprise) was simply great.

hi...
am using pocket oc 6.0.
i have to read a text file.
what is the procedure?
can anybody help me?

I'm assuming you're using C++, as you're posting here. Reading a text file is the same on a normal PC as it is on a mobile PC. So, you're better writing a test program on the PC first, as that's easier to experiment with.
Look at CreateFile, ReadFile and CloseHandle functions.
But for more detailed help, you'll need to write more detailed questions.

hi...
am using vc++ and pocket pc6.0.
am having a file like paul.doc.
and paul file condains { hi this is paul};
now i have to read the paul.doc and i have to store the datas in a string...
can anybody help me?

In your first message, you said you had a text file. If you look on MSDN for the SDK functions I gave you, you can read data from a file.
Now, you say it's a DOC file. If this is still just a text file, look at my previous answer. If it's a Word document, then it's going to be a lot harder. Those files contain all sorts of things, (author info, fonts, bold etc) and not just the text.
What is the format of the text file?
If it is in word format, can you ask whoever is giving you this file to make it a friendlier format?

its a doc file.
can you help me?

Then it's gona be a lot harder. Google for Word automation and read tutorials about it. It's much too long to explain on a forum.
Can't you use a simple text file (.txt) ? That will be much easier.

What about using C++ ifstream class?
This is a very basic task, you can also check out some documentation samples, I suppose.

Hi friends...
I need ur suggestion .how to converting datas file into CStringArray?
how its possible
Thanks n Advance

For instance reading line by line (or value by value) adding the read content to the array, i.e Dont' you think the question is a bit too broad?

is my syntax..is correct??
CFile file;
CStringArray get_array;
get_array=file.GetLenght();
is this correct....
Thanks

OK.

Nope. What do you want to do with the above line?

You should consider how your file is structured (is it a text file or is it a binary one, has a regular format ?), then you have to use some function to read in a meaningful way the file constent (for instance fread for binary files, fscanf for text ones,...) then you need to use (as suggested by Iain Clarke) the CStringArray::Add method to add read elements to your array.

You can't be serious. Before posting here, trying reading the documentation for the objects you are using.
get_array is a CStringArray, which (as the name hints) is an array of strings.
file represents a... file. GetLength does what is says - it gets the length of the file.
You've just written...
"An array of strings" = 973.
You could always try and compile your code to find out if your syntax is correct. Mr Pallini's time is more precious than your computers.
What CPallini told you is to read the file one line at a time, and add it to the CStringArray.
If you look at CStringArray, it has a member function called Add, which takes a string or TCHAR *. You need to use that inside some sort of loop.
Also, if you look at CStdioFile instead of CFile, it has a friendly method called ReadString, which makes reading from a text file much simpler than reading from a CFile.
Hopefully you should be able to put something together now.
Good luck!
Iain.

Hi,
I need to determine and anticipate when the exception 'Out of memory' occur. The first easy case is scanning the virtual memory size due to 2GB limtation in 32Bit OS (or 3GB, depends of the config).
But, this exception can occur in other circumstances. I suspect that the limit value 'Commit Charge' is reached. I don't know how to get this value.
Somebody can help me in this case ?
Thanks

If you're being paranoid (which is what we do - I'm not criticising!), then the only answer to give is...
"at any time, for no good reason".
After all, you could check for nice ambient conditions for your software, then 1s later, some other program goes on a ram-guzzling spree.

Hi,
Thanks for your response !
But I don't think what Windows handle the 'Out of Memory' exception "at any time, for no good reason"...
The problem is : I don't know how to get the 'Commit charge' values showed by the TaskManager. I'm sure that is a/the way to determine this case.
Somebody can help me to get these values ?

Hi all,
I add a file name(a string) into a buffer as follows.
int iL = strlen(m_strTemp.c_str()) + 1;
char *buff = new char[iL];
strcpy(buff, m_strTemp.c_str());
Then later I want to get that string from a buffer. So I do the following.
string *pp = new string(buff);
But gives an error on strlen.asm file as follows.
Unhandled exception at 0x102157d0 (msvcr71d.dll) in GroupServer.exe: 0xC0000005:
Access violation reading location 0x00000000.
Can you guys found where I'm wrong.
I appreciate your help all the time...

Did you use your debugger to check where the code crashes exactly ? On which exact line does it crash ?
