I got it working. Thank you.

What I wanted is just one "EXIT" to be present in the right click menu.
So I just had EXIT in top most menu.
Then I added another item Exit in it's submenu and it works, shows only the submenu.
thanks again.

If I understood u right, you dont want another process to access the file when ur program is using it, to do this use CFile::shareExclusive with the Open operation.

if u open a file while in read-only, u cant write in it unless u clear this attribute, so that ur program crashes.

Im not sure I understand all you're saying but :-

assuming : - LPCTSTR lpFileName

DWORD dwFileAttributes = GetFileAttributes( lpFileName);
long mask = dwFileAttributes;
if( ! ( dwFileAttributes & FILE_ATTRIBUTE_READONLY))
{
mask = dwFileAttributes | FILE_ATTRIBUTE_READONLY;
if( ! SetFileAttributes( lpFileName, mask))
{
// Flag the error here
return;
}
}

is probably what you're looking for - your program would of course have to remove the readonly flag before it used the file - the suggestion above this is also valid (ie exclusive flag)

Hello Garth,
yes, this is that what im looking for!
but need some help again!
Please check this code:

<br />
// <br />
// first i check if is ReadOnly File!<br />
DWORD dwFileAttributes;<br />
DWORD mask;<br />
<br />
dwFileAttributes = GetFileAttributes(csFileName); // dwFileAttributes have now 0x00000021, ok, is archive and readonly protected<br />
mask = dwFileAttributes;<br />
<br />
if((dwFileAttributes & FILE_ATTRIBUTE_READONLY))<br />
{<br />
mask = dwFileAttributes & FILE_ATTRIBUTE_NORMAL; // mask have now 0x00000000, why not 0x00000020->archive! Ok, not nice but this let me to open my file!<br />
if(!SetFileAttribute(csFileName, mask))<br />
{<br />
	AfxMessage(csErrorMessage);<br />
}<br />
}<br />
<br />
// to open file with mask == 0x00000000 make no problems<br />
cMyFile.Open(...);<br />
// write some data to file<br />
// close file<br />
// now set the flag ReadOnly:<br />
dwFileAttributes = GetFileAttributes(csFileName); // here returns a value 0x00000020 // ok, is an archive!<br />
mask = dwFileAttributes;<br />
if(!(dwFileAttributes & FILE_ATTRIBUTE_READONLY))<br />
{<br />
mask = dwFileAttributes | FILE_ATTRIBUTE_READONLY; // mask have now 0x00000021 // archive and readonly protected<br />
if(!SetFileAttributes(csFileName, mask))<br />
{<br />
// errorhandling<br />
}<br />
}<br />

This is what im doing with your response!
Is this right, take a look to my sample please!
Maybe is not the best way, but they do wat i want! Confused | :confused:

with best regards

I would have done :-

DWORD dwFileAttributes = GetFileAttributes( lpFileName);
long mask = dwFileAttributes;
if( dwFileAttributes & FILE_ATTRIBUTE_READONLY)
{
long mask = dwFileAttributes & (~FILE_ATTRIBUTE_READONLY);
if( ! SetFileAttributes( lpFileName, mask))
{
// Output Some sort of error here
// Could not make (file) READ WRITE
return;
}
// Good - Output Some Soft of Message here ?
// (file) Is Read/Write
}

not sure if that answers your question

See WIN32_FIND_DATA
The first parameter to this has the information about the file/folder attributes.
FILE_ATTRIBUTE_DIRECTORY-The handle identifies a directory.

Somethings seem HARD to do, until we know how to do them.
