Hi,
If you can not give answer then keep quite.
But it will great if you giv atleast a hint to a solution

No I won't. Now what are going to do?

Sure no problem. Think first then write code then observe the results. Now repeat as many times as necessary.

I'm trying to find an easy way to convert a CString to a char* without having to do it character-by-character.
I've tried memcpy unsuccessfully. Anyone have any tricks?
|
|
|
|
|
CString provides a (LPCTSTR) cast operator for this.BTW, what are you trying to achieve ?
can't you just use CString::operator[]() or CString::GetAt() to retrieve a character in the CString object ?
|
|
|
|
|
I want to get the entire string into a char array in case I can't figure out how to do something else.

I believe toxcct meant "what do you want to do that for ?"

exactly.
As I am suspecting the OP to have asked this for a darken reason, I'm not sure casting the CString object would be worth it...

NO, definitely not !
GetBuffer() is not there for casting purpose !
Moreover, the OP seem not to really know what he wants that for, so instead of saying amen to a query-for-code, better understand why such a thing is asked for...
I'm more likely to think he's trying to iterate on every characters of the string, so no need for cast for this ; a simple use of the [] operator would do !
BTW, I'm almost certain that Roger Allen (which is also a great codeproject member) would not reply so nowadays... notice that he replied so, but it was in year 2000 !
at last, read this[^] and tell me if you see somewhere in Microsoft recomendations to use GetBuffer().

I was merely posting a link to a thread that was of the same subject - I was not involved with any of those thread posts I thought it would be helpful to USAFHokie80 here..

Yeah... GetBuffer doesn't work.
But this works:
char* str = (char*)(LPCTSTR)str2

hum, correction : GetBuffer DOES work, but it's not there for that.

That's a horrible cast, and a good example why casts are bad. If you needed the
cast to get that to compile then you did something wrong.
It should be
const char* str = str2;
If your CString is always based on a "char" character type, then you
should be using a CStringA.
Mixing generic and fixed character types negates the usefulness of
generic character types (i.e. your code will fail on a Unicode build).

Is there an easy way to search a CFile for a string and get the index?

No you have to search the file line by line
USAFHokie80 wrote: get the index
The index based on what?
Why is common sense not common?

the index for a file position where the string begins.

Yes, assuming you put the contents of said file in a searchable buffer

I want to check whether the current user has the rights to delete a file.
I've looked at two approaches. The first is to call CreateFile with the creation disposition flags set to OPEN_EXISTING. This would give the right answer most of time, apart from when the user has the delete permission explicitly disabled.
I've also looked at GetEffectiveRightsFromAcl. This looks as if this would do it for local files, but the documentation states A trustee's group rights are enumerated by GetEffectiveRightsFromAcl on the local computer, even if the trustee is accessing objects on a remote computer. This function does not evaluate group rights on remote computers. which implies that it's not going to be reliable on a network drive, which may be hosted on a different OS anyway.
Could someone suggest a better way of doing this?
