Why? The CString class provides all you need.

Yes, since it is Unicode.

I don't know if anyone else mentioned this, but if you're going to go through all your code
and change it to work on Unicode, then I recommend in addition to changing all the char to TCHAR
also change all the CRT string calls to generics as well: strcpy = _tcscpy, strlen = _tcslen,
etc. instead of changing them to the wide character version.
That way all the code will be generic and you'll be able to reuse any code easier in any project
regardless of the character set settings.
It doesn't take that long to convert - I did a huge set of projects in a couple hours

Hi all
well i have a lil problem here
I have created few classes and stuff and i have used normal char type variable.
Now when i am writing code for UI, i have to use function strlen, strcpy , strcmp...
For instance if i do...
<br />
char str[10];<br />
CString Password;<br />
strcpy(str, Password);<br />
In above code i get error saying can not convert parameter 2 from 'CString to const char*'
So to overcome this problem i made these changes as shown below...
<br />
wchar_t str[10];<br />
CString Password;<br />
wcscpy(str, Password);<br />
This solved my error but now i have many other errors. where i used char . So now do i have to change the whole application where i have used char. All the functions and stuff..
Is it now compulsory to use unicode in MFC....??? I am new to MFC so new to Unicode thingy..bit confusing though..
Can any one shed some light over this..
Any or all help would be greatly appreciated..
Thanks a lot

if you define _UNICODE you have to follow unicode. For CString to const char* error you could have used some macro for typecasting. no need to go for WCHAR. There are many other ways to e.g. password.GetBuffer(Password.GetLength()); which will return yoi char *.

oh i wasn't aware of this.I already started changing stuff and error seems to be never ending. Hmm i got a backup of project though... So i guess i need to start it again.
Well i have not define _UNICODE...and what could be solution you could think of in the problem i mentioned.
Can we still use unicode without defining _UNICODE. I guess we can cos few things are working when i changed to wchar_t and i have not defined _UNICODE anywhere...
Thanks

It's not compulsory to use Unicode, you can remove the /D UNICODE from the MSVC project settings, but it is generally a good idea to go Unicode these days.
The short answer to whether you are going to have to change all the code or not is YES and the sooner you do it the less painful it will be
One option is to change your strcpys for tcscpys etc so that the code will compile with and without UNICODE defined. This way you can do the transition more gradually and in the meanwhile non Unicode builds which mix TCHARs with chars will work, keep putting in the changes to TCHAR functions until the code also builds and works in UNICODE. TCHAR and tcs functions turn into wchar and wcs with UNICODE defined(remeber to define _UINICODE as well beacuse someone at Microsoft screwed up) and they turn back into ordinary char stuff in non Unicode builds. You'll need <tchar.h> included of course.

Hi,
Always uses TCHAR instead of char / wchat_t and the generic-text functions defined in Tchar.h.
This will maps appropriately if used _UNICODE or not.

someone would tell me how to check a socketport is open(active) or not?
if it is active I want to close it,otherwise I would skip this work.
GoodLuck!

Hey,
try this link

and this

Did you mean if I want to get such target I would have to using CSocketFile?
But I did no need to using such class.I only want to indicate the socket is active or not,if so,I would close it.

Is there any harm in closing an already closed socket? If so, then maybe you could use getsockname() or getsockopt(), and check for WSAENOTSOCK.

Oh,I see what did you mean. That is to say,I can close a socket no matter it is opened or not.
Thanks

I *think* you can. I don't work with sockets so you'll need to test it to be sure.

There must be some nice simple function i can use to get the full directory location of where i am running my program from. Lets say my program is "me.exe" from "C:\WINDOWS\stuff\me.exe", then i want to get "C:\WINDOWS\stuff" or "C:\WINDOWS\stuff\" .
My search failed so thats why im asking here, thanks
edit: im in visual studio with a MFC dialog based application
edit2: maybe i should add i want to find the full directory from the program itself, so it knows where its running from...

Do you need to GetModuleFileNameEx?
|
|
|
|
|
Is there something less hightech and more simple?
Like none of the DWORD and all the other stuff
(i edited my question abit)
//Johannes
|

|
|
|

Im using the code:
TCHAR szPath[MAX_PATH];
GetModuleFileName(NULL,szPath,MAX_PATH);
AfxMessageBox(szPath);
however the messagebox show the full path and the executable name, i just want the full dir,
thanks
//Johannes
|
|
|
|
|
if i use that in combination with
PathRemoveFileSpec(szPath);
it works
thanks WhiteSky!

Dear Friend,
Sometimes when I try to select file from the desktop in release mode, application closing without message. In debug mode there is error message saying "Unhandled exception at 0x7d64159e in Project1.exe: 0xC0000005: Access violation reading location 0x02f24b20." In call stack window, there is shell32.dll!7d64159e().
If I uninstall Adobe reader it is not happening.
Is there any way to fix it without uninstalling Adobe reader?
Best Regards,
Suman

How do you call CFileDialog ?
|
|
|
|
|
Here is code:
<br />
char szFilters[] = "CSV Files (*.csv)|*.csv|";<br />
CFileDialog dlg(TRUE, "CSV", "*.csv",<br />
OFN_FILEMUSTEXIST| OFN_HIDEREADONLY, szFilters, this);<br />
if(dlg.DoModal()== IDOK)<br />
{<br />
CString strPath = dlg.GetPathName();<br />
}<br />
The code is inside a function of class derived from CMDIFrameWnd.
Best Regards,
Suman
