A whole new phraseology has evolved. Post a link or reply with a smiley and rose, and you've made a "Satipsism". So what?

Best wishes to Rexx[^ handle of SDI application rp_suman29-Jul-07 20:51 rp_suman 29-Jul-07 20:51  How to get the handle of SDI application similar to getting handle in Dialog-based application like: (CWnd*)AfxGetApp()->m_pMainWnd? Any help would be greatly appreciable, Best Regards, Suman Re: handle of SDI application prasad_som29-Jul-07 21:08 prasad_som 29-Jul-07 21:08  You can follow same method. m_pMainWnd represent main window object, associated with application. So it does not matter, what application type is. In case of SDI it will represent main frame window associated with application.

I have tried that, and it is giving NULL. Thanks for the help!!

Divide By Zero/NULL pointer exceptions vikramlinux29-Jul-07 20:37 vikramlinux 29-Jul-07 20:37  Hi All, Under Microsoft C++ compiler Divide by Zero and NULL pointers can be catched using try { } catch(...) { // exception handling } When I try it under the GCC on unix platforms it does not catch it. Simply "Segmantation fault" is thown outside and program terminates. I am just wondering that above mentioned exceptions and not part of C++ standard? If so, anybody have any more information on this? Re: Divide By Zero/NULL pointer exceptions Stephen Hewitt30-Jul-07 15:38 Stephen Hewitt 30-Jul-07 15:38  MSVC6 is crap; GCC is behaving correctly according to the C++ standard. The catch keyword is only meant to be able to catch C++ exceptions thrown with the throw keyword; not arbitrary hardware exceptions. Later versions of MSVC corrected this behaviour but added the /EH?[^] switch to choose between to two behaviours. Steve how to add rightclick mouse buttons in scintila wnd mirraa29-Jul-07 20:14 mirraa 29-Jul-07 20:14  hi i'm programming a document using scintilla wnd... here on right clicking mouse button my own popup menu should come..but by default it is showing some popup menu with cut,copy,paste... i have added mine using RButtonUp function but it is not sensing that function...any help please..thanx in advance... Re: how to add rightclick mouse buttons in scintila wnd Iain Clarke, Warrior Programmer30-Jul-07 1:04 Iain Clarke, Warrior Programmer 30-Jul-07 1:04  Have you tried overriding OnRButtonDown? After all, that happen first... Or checked if there's an overridable member OnContextMenu? Lastly, have you added the macros (ON_WM_RBUTTONetc) to your message map? You need to hook up your handler as well as write it. Iain. Re: how to add rightclick mouse buttons in scintila wnd mirraa30-Jul-07 1:30 mirraa 30-Jul-07 1:30  yah!i have tried with adding WM_RBUTTONUP message using class wizard but it is not at all sensing the function when i press rightmousebutton ...even i tried with WM_RBUTTONDOWN through class wizard,neither is working.... i have avoided the default scintilla wnd's popmenu also by using SCI_USEPOPUP(false)... as you said these WM_RBUTTONUP are working well in other windows not in scintilla wnd... any help thanx in advance....

WhiteSky Removing non-empty directory George_George29-Jul-07 19:45 George_George 29-Jul-07 19:45  Hello everyone, I am wondering how to remove a non-empty directory on Windows? I find that function RemoveDirectory works only for empty directory. thanks in advance, George Re: Removing non-empty directory mandanani29-Jul-07 20:10 mandanani 29-Jul-07 20:10  A quick search give me the below link. I have not tested/used. http://www.codeproject.com/cpp/Clean_Workspace.asp Re: Removing non-empty directory George_George29-Jul-07 20:40 George_George 29-Jul-07 20:40  Good reference, thanks mandanani! Since I need to use API DeleteFile, I am wondering how to pass path name string which is encoded as multi-byte character or wide character? In the article, it is an MFC project so CString is used, but I am not using MFC based Windows project, and I can not use CString data type. Any ideas? regards, George Re: Removing non-empty directory Roberto Italy29-Jul-07 20:18 Roberto Italy 29-Jul-07 20:18  To delete a non-empty directory I usually use a loop with FindFirstFile()/FindNextFile(). If you want to delete a whole subtree, you can make a littel recursive function using the above calls: it is very simple. Pay attention to the read-only files: you should change the read-only attribute (if you can) before removing them. Hope this helps.

Or try using it and fail? Iain.
