If I am not wrong,
Unless u close the handle ,u cannot open the same file again.
If u want to read and write at the same time use flags like CFile::modeReadWrite

Thats i know.
My problem is that this file is opened for write by another application. I have no information about this application.
I want to read it from my application.

Then to my knowledge,it is not possible to read .

It all depends on the share mode used to open the file. If the other application opened the file with READ access and using FILE_SHARE_READ, then you can read the file. Try opening the file with the same and see what happens.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I made the file association of my file type with my application, and now when I double click the file, it opens my application but gives the error message
"Windows cannot find 'c:\downloads\file.hs1'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search."
The file path is shows is the file I just clicked, so it obviously exists.
what i have to do.

it's fine that you are having an API with which you have to connect to a server.But you forgot to mention about 1) - with what protocol do you want to connect and provide some details of the application.
Somethings seem HARD to do, until we know how to do them.

Why on earth are you declaring a C++ member function to be exported from a dll? If you just want a particular calling convention, say so, though perhaps member functions require __thiscall. However, unless it's just late and I'm being stupid, you can't call anything but a static member function from a dll because it's missing the this pointer.
I assume that the CView object code is in dll.lib? Can you instantiate CmView?

I have a problem in file reading.When i write to the file,it writes very correct.but during reading it doesn't read anything.
e.g,I have to write some details of SWFLOW,SWT,VCOn,STEMP etc.,the code for writing
struct STagTabFile TabFile;
CDisplay *pTemp;
FILE *fpTab;
if( (fpTab = fopen( szFileName, "w" )) == NULL )
{
MessageBox( "Unable to open" );
return FALSE;
}
for( POSITION indx = DisplayList.FindIndex( GetTopIndex(ActivePage) ); indx != NULL; )
{
pTemp = (CDisplay *) DisplayList.GetAt( indx );
strcpy( TabFile.VarName, (LPCTSTR)pTemp->DisVar );
TabFile.OffSet = pTemp->OffSet;
fwrite( &TabFile, sizeof( struct STagTabFile ), 1, fpTab );
DisplayList.GetNext( indx );
}
fclose( fpTab );
return TRUE;
}
FOr reading,
if( (fpTab = fopen( szFileName, "r" )) == NULL )
{
MessageBox( "Unable to open " );return FALSE;
}
while( fread( &TabFile, sizeof( struct STagTabFile ), 1, fpTab ) )
{
if( ( DisplayBuf = new CDisplay() ) == NULL )
{
MessageBox( "Out Of Memory" );return FALSE;
}
DisplayBuf->DisVar = (CString)TabFile.VarName;
DisplayBuf->OffSet = TabFile.OffSet;
DisplayList.AddTail( DisplayBuf );
PutDataInScreen( DisplayBuf );
} fclose( fpTab );
This is my coding,when i read the values for SWFLOW,SWT,VCON and all other it reads the value perfectly.
In case of STEMP it does not enter in to while loop,it comes out.Whats the reason,if there is any mistake in my coding means it should not read for all variables,but it reads for all variables except STEMP.wats the reason?

Instead of
fwrite( &TabFile, sizeof( struct STagTabFile ), 1, fpTab );
try Typecasting for void*
fwrite((const void*)TabFile, sizeof( struct STagTabFile ), 1, fpTab );
//FWRITE is
//size_t fwrite( const void *buffer, size_t size, size_t count, FILE *stream );
For FREAD
size_t fread( void *buffer, size_t size, size_t count, FILE *stream );
I hope this will help

What type of connection do you need (TCP or UDP)? Are you supposed to be initiating the connection, or are you already connected at this point (since the function is called OnConnectedToServer) and you have to write some code to handle the connection? A little more info about what exactly you need to do would allow us to answer your question much more effectively.

i already but lots of confusion:

Just try something yourself, post your doubts when you get stuck somewhere. Then all can help you better.
Good Luck...

(1) kindly stop spamming the forums -- you've posted a nearly identical post at least 4 times
(2) do some work yourself. Here[^] is but one of many pages. Go read it, compile the sample programs, make them run, then write some code.
