Nothing was ever mentioned about changing it, only to verify that the method exists.

if(cpi->eurodate==1){

Why do this check if the other check evaluated to true (i.e, cpi->eurodate can't be both 1 and not 1).

Sorry, you are correct and it is there... interesting... eventhou I included this header...

// Attributes
COLORREF GetMonthCalColor(int iColor) const;
COLORREF SetMonthCalColor(int iColor, COLORREF ref);
BOOL SetFormat(LPCTSTR pstrFormat);
CMonthCalCtrl* GetMonthCalCtrl() const;
CFont* GetMonthCalFont() const;
void SetMonthCalFont(HFONT hFont, BOOL bRedraw = TRUE);

To answer your seconrd question:
This is a 3rd party app which has a switch for EURO Date Format or NOT. I support a DLL that interfaces with another system. Yes, like you I would have used Windows configuration.

thanks again...

I understand that, but there's still no reason to perform both if() tests when only one of them can evaluate to true. I would imagine that the compiler would realize that and perform the necessary optimization, but still.

I have a problem like i need to include a different header files depending on the linux kernel in a .cpp file. I have to check the linux kernel version and include the headerfile depending on that kernel. How can I do that?

I have ARCH variable in Makefile, can i make use of that?

Best way it to first include keranal version.h file in your project (ex:"/usr/include/linux/version.h"), and then put below checks in your code.

#if RHEL_MAJOR == 5

#include "xyx_5.h"

#else

#include "xyx.h"

#endif

lOOKS LIKE this doesn't work for me. I saw the version.h file, it has got 3 lines as below.

#define UTS_RELEASE "2.4.20"
#define LINUX_VERSION_CODE 132116
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))

And I want to differentiate kernels for 2.4 and 2.6. Is the above code still works with it.I've placed my code as below, but it seems not working.

#include "/usr/include/linux/version.h"

#if RHEL_MAJOR=2.4.20
#include "../../build/i686-Linux-2.4.32/ReleaseVersion.hh"
#else
#include "../../build/i686-Linux-2.6.21/ReleaseVersion.hh"
#endif

What went wrong in my case.

Thanks in advance WTF | :WTF:

Try below code,

//include for version 2.4 or lower
#else
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,0)
//include for version 2.6 or higer
#endif // 2.4
#endif //2.6

The strange part of this is that i could build the sources before installing the oldest version of WinDDK. And i have never changed any lib files that are linked to my project.
Thanks anyway.

Looks like you're linking against the wrong C/C++ run-time libraries. Check that the correct Visual Studio directories are in the VC++ library path (Tools->Options->Projects and Solutions->VC++ Directories and select 'Library files' for the 'Show directories for:' combobox).

CListCtrl::OnTimer()

15-Apr-09 2:34

Hi all,

I have a customized ListCtrl, and Called SetTimer() but OnTimer() handler will execute only once..

And I does not called any KillTimer(),

My OnTimer is Like this

<br />
void ListCtrlEx::OnTimer( UINT nIDEvent_i )<br />
{<br />
    if( 100 == nIDEvent_i )<br />
    {<br />
        // Do some thing<br />
    }<br />
    CListCtrl::OnTimer( nIDEvent_i );<br />
}<br />
<br />
// My set timer is in MouseMove<br />
// If mouse butto is pressed<br />
SetTimer( 100, 300, 0 );<br />

Any possible reason for the same

Regards,
Radhakrishnan G.

Don't called default OnTimer of CListCtrl, for your timer ID.

void ListCtrlEx::OnTimer( UINT nIDEvent_i )
{
if( 100 == nIDEvent_i )
{
// Do some thing
}
else
{
CListCtrl::OnTimer( nIDEvent_i );
}
}

Thanks in advance.

You will probably need to have to handle NM_CUSTOMDRAW and do the drawing yourself.

I suspect you'll need to resort to custom drawing. Here's a page[^] describing how custom draw works for tree controls.

And here's just one example of a CP article that uses custom-draw with a tree control[^].
