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; // Prop page

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 Sigh | :sigh:

i explain:
when i do the following, it works :

//CFunctionsPage m_FunctionsPage
this->FunctionsPage.m_psp.dwFlags  |= PSP_USETITLE;
FunctionsPage.m_psp.pszTitle  = "Environment";

but this doesn't Frown | :(

//CFunctionsPage m_FunctionsPage
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.

Dynamic memory allocation of 2-D array

1-Feb-06 23:29

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... D'Oh! | :doh:

)

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

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.

No Balloon Tip

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

You have to set the version.

ndata.uVersion=NOTIFYICON_VERSION;
Shell_NotifyIcon(NIM_SETVERSION, &nData);

Where did you do it.

Note: uTimeout and uVersion is wrapped inside a union so you must be careful. Both cannot be used at once.

right after

ndata.cbSize = sizeof(NOTIFYICONDATA);

Owner drawn31-Jan-06 23:26

31-Jan-06 23:26

No you are wrong.

First set the icon:

Shell_NotifyIcon(NIM_ADD, &ndata);

Then the set the version:

ndata.uVersion = NOTIFYICON_VERSION;
Shell_NotifyIcon(NIM_SETVERSION, &ndata);

The reason being that you cannot use both uVersion and uTimeout together since they are wrapped inside a union.
