How to use CString with more than 255 characters?

I need to pass a CString which sometimes contains more than 255 characters.
How can I do that?

Where to pass?
Please be more explicit.

A CString object can store up to INT_MAX (2,147,483,647) characters. Why you are fearing for just 255 characters?

Have a look at below link...

http://msdn.microsoft.com/library/de...tring_data.asp

ok, I have an array of strings. I need to copy a number of entries in this array to a single CString variable, something like:

for (int i = 0; i < 10; i++)
myStr += myStrArray[i];

So, if the number of characters in these entries exceeds 255 then myStr won't contain the rest which exceeds 255.

:cool:
Are you sure? Just try this:

Code:

---

CString strBig(_T('A'), INT_MAX - 1);

---

so, any idea what I can do about this?

Just add this:

Code:

---

int nLength = myStr.GetLength();

---

and I assure you can get more than 255.
Possible you have seen max. 255 in the output window. There is a limitation, indeed.

Well...post your code where you fill the string...

Are you sure based on that ASSERT(nLen <= INT_MAX-1) from CString::AllocBuffer?

ok, if I read the length it gives me more than 255 so probably it is indeed the limitation of the watch?!
So, the problem must be somewhere else. The thing is, I am exporting this string into a cell of an excel sheet and in the sheet I am seeing only 255 characters so first i thought it was a limitation of the cell length in the sheet but if I fill a cell by hand with more than 255 chars, it works. So now I'm pretty lost about where the problem could be....

thanks anyway guys!
If you still should have an idea, please let me know!

How are you doing that?

Using ODBC

RFX_Text has a 255 character limit. That's probably your problem.

No...I am sure based in the class code itself...
