Hi,
Why You are not happy with this link, you have posted the message once again?

I am not familiar with Accessibility API.

I suggest one method, Keep the text information and position expliclitly of all the Text String drawn using drawtext() and on mouse click() select the text from the data using a simple rectangle collision(hit test) from the mouse pos.

Best Regards
Raj.

Or make an CObject derived class with "position" and "content" as members.

Then when you click, take check out if the click is where you want. If one object has this point in its "position" range, make whatever you want with the "content"

Any suggestions for the above problem

Hi,

use wifstream in place of ifstream,
it seems your project is unicode defined.

you may use

 #ifdef _UNICODE
wifstream message_file;
#else
ifstream message_file;
#endif

Why are you mixing Generic-Text Mappings with a class specialized for elements of type char?

Try to change the above with:

well i am well confused now. okay pls have a look over this post of mine where i discussed mainly about char variable...

http://www.codeproject.com/script/comments/forums.asp?forumid=1647&select=2073148&df=100&fr=26

Now all of them said me to use TCHAR in place of char or wchar_t..
I have not defined UNICODE...All of them said that TCHAR can handle both UNICODE nad non UNICODE ...So its always better to use TCHAR.

Now i am finished changing every related char to TCHAR and left with 1 error which i asked ...

Well yeh i am rewriting mfc VC++ code to VS2005(MFC)...so am facing promlems...m new to MFC...

Now if ill change message back to char ill again get many errors so that means i have to change everything again....and would end up in never ending error loop....
Any other way out...?

Thanks

Hi,
Yes, It's nice choice of using generic text mapping function.
So that you can compile both in unicode and non unicode version.

Well C++ stream class has both version,
whar_t version of "ifstream" is "wifstream", "cin" is "wcin", ...
but i don't know the generic mapping for these class.

map these classes yourself for unicode and other version.

Well, they're right: actually TCHAR works both for UNICODE and not-UNICODE builds. The same is not true for ifstream that is a class specialized for handling char buffers.
YOu can either follow my suggestion or accept the more elegant solution of Rajkumar_R [^].

This is the default for VS2005. Change ifstream to wifstream as has been mentioned.

YEH thats true...
Do you think it could be cos i am using TCHAR now. Whereas i guess wifstream supports wchar_t...
Is there any class for TCHAR types...i dont think so..????

No, because the preprocessor has resolved those to wchar_t.

okay

These were my main problems cos of which i first used wchar_t and now TCHAR...

char str[10];
CString Password;
strcpy(str, Password);

In above code i get error saying can not convert parameter 2 from 'CString to const char*'

TCHAR strFilter[1000];
_tcscpy_s(strFilter, "All Files (*.*)|*.*||");

And error i got is none of the 2 overloads could convert all the arguments type.

If i get some other way to deal with this situation... I mean without using wchar_t or TCHAR or L or _T or wcscpy or _tcscpy_s etc etc...then it might work...Dont know really..lez c ..m playing around with it at the moment...

Thanks

Doesn't this require three arguments?

The string literal needs to use _T() or L.

In any case, do you really need to use wchar_t variables?

So what of your "And error i got is none of the 2 overloads could convert all the arguments type." comment? That does not sound like it is working, or right, to me.

oh by that i meant to say it was working like this...

<br />
CString strFilter;<br />
const TCHAR *strSource= _T("All Files (*.*)|*.*||");<br />
_tcscpy_s(strFilter, strSource);<br />
<br />
<br />

So Parameter isn't a problem in that...

Confused | :confused:

How is this not generating a compiler error? I would have expected it to be:

_tcscpy_s(strFilter.GetBuffer(128), strSource);

In any case, why would you want to use _tcscpy_s() with a CString object? That makes no sense.

Sorry... my brain is nt workin enough nw....need lil break..
actually it was

TCHAR strFilter[1000];
const TCHAR *strSource=_T("All Files(*.*)|*.*||");
_tcscpy_s(strFilter, strSource);

And this was definately working....i tested it aswell

Rest ill find out after i finish writing these functions ....hoping for the best... Smile | :)

So why introduce an unnecessary variable (i.e., strSource) when

TCHAR strFilter[1000];
_tcscpy_s(strFilter, _T("All Files(*.*)|*.*||"));

would have sufficed? Since you are using MFC, why bother with wchar_t variables at all?
