I think you misunderstood my reply...
I mentioned that sentence, for the parameter to CreateFile API...
to represent a file name.. thats it...
I didn't say that, we never need a typecast..

Hi toxcct,

Sorry i'm not clearly read your post. Blush | :O

To make the string always UNICODE we have to use L or someother converting macro.
Sorry once again...

why not using C++ cast operators ?!

Problem was not related to this, just ignored that. Smile | :)

Notice that those 2 lines of code are quite the same, because is unicode is not defined, _T() simply equals its content (just removed)...

OP is facing problem because, UNICODE is defined. Otherwise, he would not have needed to use LPCWSTR.

yes yes, i aggree with that.

but i just added that your 2nd line of code (LPCWSTR pTestCast = (LPCWSTR)(_T("Error_Occured.err"));) was not correct.

you would better have written this :

LPCWSTR pTestCast = CT2W(_T("Error_Occured.err"));

so, like that, if unicode is define, _T() transforms it to a wide string, and that's good, because CT2W() waits for a wide string in such acompilation mode;
if unicode is not defined, then your code remains the same and also compiles good for an ANSI compilation, because _T() casts into an ANSI strings, which is what CT2W() waits for is UNICODE is not #defined...

I appreciate for this information.
But in case of ANSI, it is not needed to use LPCWSTR(in context of API in OP). It would be LPCSTR rather.

So problem faced by OP was basically due to incorrect type casting. And wanted to highlight that. Might be not considered all scenarios.

that's why we should most of the time use CString, LP[C]TSTR and _T()

Caution: Registry entries are always subject to change in future versions!

how to find the edition of SQL Server 2000/2005 through registry?[^]

Better yet, get it from the server itself using SQL:

SELECT SERVERPROPERTY('Edition')
SELECT SERVERPROPERTY('ProductVersion')
etc.

SELECT @@VERSION AS 'SQL Server Version'

The first project would be to avoid using more than one user account and making it so obviously visible by posting the same question from either user accounts, one after another. Stop thinking that you are the smartest person in the world. Mad | :mad:

yes, but abusing of trolls is not well seen here. moreover, not only the guy is trolling, but he's also spamming (same question twice is definitely not needed to get a relevant answer).
