Re: how to get the VARIANT type URL as a CString from OnDocumentComplete in webbrowser2

"URL" here contains the url that has been completed. but it is a variant type.

A variant type has many different subtypes, one of which is a BSTR. For example:

COleVariant vtURL(URL, VT_BSTRT);
CString strURL = V_BSTRT(&vtURL);

Or:

CString strURL(V_BSTR(URL));

Hello all,

I was wondering if I can use the new CString class that came with VC++2005 but in VC++6...

If this is possible, how should it be done?

As always thank you in advance...

No, but you could possibly derive your own class from CString, and add methods to it that are similar to those in the VS2005 version.

CString.tokenize...

I wanted to use that and not a custom made tokenizer...

I'm sure that there are plenty of them here in CP, but well, I have an old app that deserve a little of maintenance... and I've got used to use that tokenizer...

I don't think we can do this.

Note : Please give detail which type of DSN you want to create at run time.

I think u will be aware about System DSN,User DSN,File DSN

A DSN does not know/care about the underlying DBMS. The third argument is where you specify the type, and the fourth argument contains the details of that type.

The third argument is "Microsoft Access Driver (*.mdb)" then what should changes are required?

Why the extra \0 character? This statement is missing a semicolon.

If you are using MFC, why not use a CString object rather than mess with sprintf()? This statement is also missing a semicolon.

And that error would be?

In this '\0' just for termination of string
the error is
SQLConfigDataSource is return False.

Is any problem in that syntax
