This seems so simple but I'm lost, because the web talks about SetFormat() but the class method just does not seem to exists in my C++ 6.0 version.
tried this
case WM_TIMER:
if((HWND)lParam==GetDlgItem(hwndDlg,IDC_DATETIMEPICKER4))::Set????((HDC)wParam,_T("dd-MMM-yy"));
tried this: (assertion error occurs)
// Gain a pointer to the control
CDateTimeCtrl* pCtrl = (CDateTimeCtrl*) GetDlgItem(hwndDlg,IDC_DATETIMEPICKER4);
ASSERT(pCtrl != NULL);
pCtrl->SetFormat(_T("dd-MMM-yy"));
Any ideas?

What assertion error, this one?
Don Jones BNYMellon wrote: ASSERT(pCtrl != NULL);
If so that means the control( IDC_DATETIMEPICKER4) has not been created.
Aside: It is more practical when forming comparison expressions of variables to constants, to place the constant on the left side of the comparison statement NULL != pCtrl. This way the compiler will error if you typo the statement into NULL = pCtrl whereas it won't if you typo pCtrl = NULL

Thanks for reply
Got the date --- debug shows someting is not happy Needs the Window Handle?
// Gain a pointer to the control
char datetext[25];
EnableWindow(GetDlgItem(hwndDlg,IDC_DATETIMEPICKER4),true);
GetDlgItemText(hwndDlg,IDC_DATETIMEPICKER4,datetext,25);
CDateTimeCtrl* pCtrl = (CDateTimeCtrl*) GetDlgItem(hwndDlg,IDC_DATETIMEPICKER4);
ASSERT(pCtrl != NULL);
debug
+ datetext 0x0011f16c "4/15/2009"
+ hwndDlg 0x00050736
+ pCtrl 0x00000000 {CDateTimeCtrl hWnd=???}

Have you looked in afxdtcl.h (line 50)?
Rather than force a particular format, why not use whatever Windows has been configured for?

Nice call but got another solution, so I don't have to change afxdtc.h
Here's what works.
if(cpi->eurodate!=1){
SendDlgItemMessage(hwndDlg,IDC_DATETIMEPICKER4,DTM_SETFORMAT,0,LPARAM("MM'/'dd'/'yyyy"));}
if(cpi->eurodate==1){
SendDlgItemMessage(hwndDlg,IDC_DATETIMEPICKER4,DTM_SETFORMAT,0,LPARAM("dd'/'MM'/'yyyy"));}
Thanks for all your help....

Nothing was ever mentioned about changing it, only to verify that the method exists.
Don Jones BNYMellon wrote: 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

Try below code,
#if LINUX_VERSION_CODE <= KERNEL_VERSION(2,4,0)
#else
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,0)
#endif // 2.4
#endif //2.6

Hi All,
I have problem with my project linking.  It fails and the errors are
error LNK2001: unresolved external symbol __RTC_Shutdown
error LNK2001: unresolved external symbol __RTC_InitBase
error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(char const *)" (__imp_??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@PBD@Z)
error LNK2001: unresolved external symbol ___security_cookie
and a lot such us.
Can anybody tell me what can be the reason?
Thanks

Not linking with the correct library, perhaps?

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).

Hi. Thanks for answer but it's ok with the Library Files.

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 />
}<br />
CListCtrl::OnTimer( nIDEvent_i );<br />
}<br />
<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 );
}
}

I am using MFC Treeview control in my application. For each tree node has some images. usually the image is left side of the tree node but i would like to add this image after the text of the node.
Can you please suggest some ways to do this?
Thanks in advance.

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