Here is my "Debug works, Release crashes" checklist:
-check for uninitialized variables, esp pointers.
-check build settings that only release mode libraries used
-look for ASSERT's with non-const expressions - use VERIFY here instead
-in MFC, look for mismatched message handlers, esp for OCX's.

Hi all
Please tell me how to temrinate an EXE which was created from the VC++ application using "ShellExecute".
To use TerminateProcess(), we should pass the handle of the process. But i how can i obtain the handle when i use "ShellExecute"?
and also In CreateProcess() function i don't find any parameter for "passing the parameter to the application to be invoked".
Bye

You can't. Use ShellExecuteEx or, much better, CreateProcess to retrieve the handle.
From MSDN:
BOOL CreateProcess(
LPCTSTR lpApplicationName,
LPTSTR lpCommandLine,
LPSECURITY_ATTRIBUTES lpProcessAttributes,
LPSECURITY_ATTRIBUTES lpThreadAttributes,
BOOL bInheritHandles,
DWORD dwCreationFlags,
LPVOID lpEnvironment,
LPCTSTR lpCurrentDirectory,
LPSTARTUPINFO lpStartupInfo,
LPPROCESS_INFORMATION lpProcessInformation
);
So what you are looking for is probably here lpCOmmandLine

I think you mean lpProcessInformation.hProcess.

Actually not, with this I was answering his second question "How to pass parameter to the invoked thing".
I agree I should have stated this more clearly.
This is not the first time you have corrected me these days, I should really pay more attention to my answers

gd' morning everyone (yup, i'm still wakin' up),
i have a problem in my wish to move every GUI Strings of my project[^] into the resource strings table.
i can easily construct the caption on the propertySheet dialog using this->SetTitle() in my propertySheet constructor.
my need comes when i try to initialize each PropertyPage's caption (which end up as a tab) using this->SetWindowText() within CMyPropertyPage::OnInitDialog(), the tabs remains empty...
when i debug, the CString is correctly loading the resource string from the string table, so i think that it is the call to SetWindowText which is not appropriate. moreover, the breakpoint in oninitdialog is reached only when i navigate through the tabs (not at the first diplaying of the prop sheet...
however, i cannot find the messages sent when a propertySheet is initializing its pages...
any one can help please ?
thanks in advance

Hi tox,
you must set the title of the property page before you come into the OnInitDialog(), e.g. on property sheet level, just before adding the page.
That way:
CPage5Dlg page5;
page5.m_psp.dwFlags |= PSP_USETITLE;
page5.m_psp.pszTitle = "Environment";

If you want to change the tab's text after the page is created, use CPropertySheet::GetTabControl() and then CTabCtrl::SetItem().

well, guess what...
it does work, but partially 
i explain:
when i do the following, it works :
this->FunctionsPage.m_psp.dwFlags |= PSP_USETITLE;
FunctionsPage.m_psp.pszTitle = "Environment";
but this doesn't  :
this->FunctionsPage.m_psp.dwFlags |= PSP_USETITLE;
CString strCaption;
strCaption.LoadString(IDS_HELP_FUNCTIONS);
FunctionsPage.m_psp.pszTitle = strCaption;
while debugging, the strCaption variable is correctly filled with the right resource string, but the variable might be destroyed when living the scope.
actually, it works only if i hard code the string to display (which is exactly what i don't want)...
any idea ?

Two ideas :
1. Try with
FunctionsPage.m_psp.pszTitle = strCaption.operator LPCTSTR();
2. Try with
strcpy(FunctionsPage.m_psp.pszTitle,strCaption.operator LPCTSTR());
Actually, as its name suggests, pszTitle is not a CString, so I presume you are right when saying the variable is destroyed after leaving the scope (In fact, you do a pointer assignment and the pointer is destroyed after leaving the scope).
If I am right, solution 1 will not even compile. So I bet solution 2 is what you are looking for.

already done both.
let me add one note to your reply code however.
cast operators overloads are designed to be used as C-Style cast.
so instead of calling strCaption.operator LPCTSTR(), simply call (LPCTSTR)strCaption
anyway, this doesn't work either...
solution 1 actually compiles, but the tab caption displays strange characters (significative to our first diagnostic).
solution 2 doesn't compile ; the compiler says that it cannot convert parameter 1 from const char* to char* (and here, i don't understand why... )

Hi,
I'd like to write a function, which returns an array of strings. But the size of the array is unknown. For example, it has to create a string array with the nos. I enter (say, "1", "2", "4", "9".. , and return back to the caller function when I enter 0. It has to grow dynamically. But I don't want to do it with built-in classes like list, vector and so on.
I'd like to use 'new' operator or 'malloc/realloc' functions.
Pls suggest me a good solution.
Thanks in advance,
Sarvan AL

Ever considered using STLs ?

Google for the head line of your question: Dynamic memory allocation of 2-D array
I got 199000 hits, several of them uses malloc.

"malloc" should nowadays be replaced with "new" as my Cpp teacher told me recently
|

I quote the original poster:
"I'd like to use 'new' operator or 'malloc/realloc' functions.

The original poster is totally free to use any technique available, as far as I'm concerned. I'm not responsible neither for the hits gotten from Google nor what sample the original poster uses.
But your teacher has got a point. In C++, it's preferred. I plain C, however, new() isn't available. And that's where malloc/realloc comes in, amongst others.

hi,
I want to display a little balloon tip on my tray icon but the balloon just won't appear, although the tray icon is visible. the app is based on MFC and here's the code that doesn't work. it is located in OnInitDialog:
<br />
<br />
ndata.cbSize=sizeof(NOTIFYICONDATA);<br />
ndata.hWnd = m_hWnd;<br />
ndata.uFlags = NIF_ICON | NIF_MESSAGE | NIF_INFO;<br />
ndata.uID = IDI_DISABLED;<br />
ndata.dwInfoFlags = NIIF_NONE;<br />
<br />
ndata.hIcon = (HICON) LoadImage(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDI_DISABLED), IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR); <br />
<br />
ndata.uCallbackMessage = WM_POPUP;<br />
ndata.uTimeout = 10000;<br />
<br />
wcscpy(ndata.szInfoTitle,_T("Test"));<br />
wcscpy(ndata.szInfo, _T("Test")); <br />
<br />
Shell_NotifyIcon(NIM_ADD, &ndata);<br />
<br />
ndata is of type NOTIFYICONDATA and is a member of my dialog class.
any clues what could be wrong with that ?
greets
