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.

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.

<complex> !?!

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"?

With time we live, with money we spend!

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.

Hello,
I think You can use RecalcLayout() function to solve this problem.

For control bars that belong to a particular CFrameWnd, you need to use the ShowControlBar() function rather than just calling CMyControlBar::ShowWindow(SW_HIDE). For example:

CMyDialogBar m_barHelper;

void CMyFrame::OnMDIActivate(BOOL bActivate, ...)
{
  if (bActivate)
    ShowControlBar(&m_barHelper, TRUE, FALSE);
  else
    ShowControlBar(&m_barHelper, FALSE, FALSE);
}

Big/Small Tic marks on CSliderCtrl

6-Feb-02 4:38

Hi everyone,

A quick question-- Does anyone know if it is possible to have big and small tic marks on a CSliderCtrl? I have a slider that has the range -100 to 100, and I would like to have small tic marks every 10, while having a big tic mark at 0, which marks the middle of the slider.

I am using

m_PCWF_slider.SetTicFreq(10);<br />
m_PCWF_slider.SetPageSize(5);<br />

Thanks for the help!

I created an ATL project and inserted into it a Composite Control Object.
It works fine , but need to read some info from the browser specified in the
OBJECT tag
<object>
...
...
<param name="myparam" value="MyValue"
<="" object="" />

How I read the MyValue from my ATL Composite Control?

Thankx Eek! | :eek:
