Probably something like this:

TCHAR* name = new TCHAR[lstrlen(pBuf->wki100_computername)];
lstrcpy(name, pBuf->wki100_computername);

Of course, don't forget to delete[] name.

how about memcpy?

I was wondering if I use memcpy, how do I get the string length of the second member of the structure which is pBuf->wki100_computername as my attempts in using strlen and its variations haven't been successful?

There shouldn't be any reason why strlen/lstrlen wouldn't work unless you are having a syntax problem or a more serious coding problem.

Well, first off you've got a problem in that you're passing the address of a pointer to the API, not the address of a WKSTA_INFO_100 struct. That's gonna corrupt your stack.
Once you fix that, use ATL's W2CT macro to convert from WCHARs to TCHARs, then _tcsdup to make a copy of the string.

USES_CONVERSION;
LPCTSTR pszCompName;
 
  pszCompName = _tcsdup ( W2CT(buf.wki100_computername) );
 
  if ( NULL == pszCompName )
    // handle error...
 
  // more code here...
 
  free ( pszCompName );

Hi,
I created a MDI app with a CRicheditView.
Works fine but I'd like to modify the Richedit style, i.e. add auto horizontal scroll to avoid line wrapping.

usualy, this is done through create(style, .....).

But I can't find where the richedit is created in the MDI appwizard generated code Confused | :confused:

help !

yeah, knew this one.

the problem il that I see only the SetOptions() method to change style, I tried :

GetRichEditCtrl().SetOptions(ECOOP_SET, ECO_AUTOHSCROLL |<br />
 ECO_WANTRETURN | ECO_AUTOVSCROLL);

but seems to change nothing.

Yes,you are right ,it doesn't work.
There is MFC sample in MSDN,WORDPAD ,maybe it helps you ,I don't
have it to check it,if you find the answer in it please reply me.

I'm looking at "Sams Teach Yourself Visual C++ 6 in 21 Days" and for the code on page 78, I get the following error for line 23's code in the book:

--------------------Configuration: Timers - Win32 Debug--------------------
Compiling...
TimersDlg.cpp
C:\WINDOWS\Desktop\Rajveer\Timers\TimersDlg.cpp(203) : error C2196: case value '1' already used
Error executing cl.exe.

TimersDlg.obj - 1 error(s), 0 warning(s)

I checked all my code for that entire project and I've typed it exactly as the book. So what is wrong?

	UpdateData(FALSE);

	CDialog::OnTimer(nIDEvent);
}

You can't have 2 cases (i.e. 2 occurences of ID_CLOCK_TIMER) in the same switch statement. Looks like you made a simple copy/paste error.

He doesn't - he as ID_CLOCK_TIMER and ID_COUNT_TIMER but they both seem to have the same value.

Hi,
I've just tried to use the c++ complex library in vc6, but if I use the complex template like this

complex<double> foo; //Definition of a variable

for some reason a compile error is generated:

error C2143: syntax error : missing ';' before '<'

does anyone know why this happens, how to avoid it, and why is the complex header file called "complex", and not "complex.h"?

insert

using namespace std;

between the #include and the first use of complex.
If you don't know what std goes about, I suggest you read the "namespaces" section of any good C++ tutorial.

CControlBar won't go away

6-Feb-02 4:38

Hi,

I have several toolbars and control bars in my application. I load different ones depending on the type of document loaded at the time. Hence, if I close one document type and open another I get different combinations of control bars.

My problem is that when I unload the control bars they do not destroy properly, the client area (i.e. the grey panel) for the control bar remains.

Is there a key step that I have missed in the process of closing a ControlBar?

The same is also true for the toolbars underneath the menus.

I think MFC sample CTRLBARS can help you. Toolbars are not unloaded or destroyed in it, they are just hidden. From user point of view this is the same.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
