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.
Pls suggest me a good solution."
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 ?

... no effect. setting the version didn't fix it 
|
|
|
|
|
|
right after
ndata.cbSize = sizeof(NOTIFYICONDATA);
|
|
|
|
|
|
|
ok here's my new code:
<br />
ZeroMemory(&ndata, sizeof(NOTIFYICONDATA));<br />
<br />
ndata.cbSize = sizeof(NOTIFYICONDATA); <br />
ndata.hWnd = m_hWnd; <br />
ndata.uFlags = NIF_ICON | NIF_MESSAGE;<br />
ndata.uID = IDI_DISABLED;<br />
ndata.uCallbackMessage = WM_POPUP; <br />
<br />
ndata.hIcon = (HICON) LoadImage(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDI_DISABLED), IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR); <br />
<br />
Shell_NotifyIcon(NIM_ADD, &ndata);<br />
<br />
ndata.uVersion = NOTIFYICON_VERSION;<br />
Shell_NotifyIcon(NIM_SETVERSION, &ndata);<br />
<br />
ndata.uTimeout = 10000;<br />
ndata.uFlags |= NIF_INFO;<br />
<br />
_tcscpy(ndata.szInfoTitle,_T("Test"));<br />
_tcscpy(ndata.szInfo, _T("Test")); <br />
<br />
Shell_NotifyIcon(NIM_MODIFY, &ndata);<br />
but still no balloon

Hi!
I have a dialog based application with severeal dialogs. There is a main dialog, which calls via Button and Menu all other dialogs.
Till now, I used only ordinary dialogs. But to make it more clear to the user, I tried to transform some of the dialog classes into PropertyPages. While using the dialog class, parameters were given to the main program while pressing the OK-Button.
Because there is no OK-Button in a PropertyPage-dialog, I don't know, how to give over the parameters now.
I Already implemented a function OnRefer(WPARAM, LPARAM), but only that was too less.
I already serached in the codeproject's articles but couldn't find something accordingly.
It would be great, if somebody could help me with this problem (Links, Hints or whatever)!!

What do you mean exactely with "refer" ?
~RaGE();

Sorry about that, my mothertongue isn't the english language.
I want to say: to send parameters, to give over parameters. Is that a better expression?

OK! I was not sure what you meant.
The idea behind the Property pages is:
You have a property sheet containing property pages.
You set up the property sheet, adding the property pages one by one, then the property sheet is called with a DoModal() from your base dialog. Now to exchange data between the property pages and your base dialog, you do the following:
The data you want to retrieve is saved in each property page in member variables.( I usually save everything in each property page in the OnDestroy() function, which is called when the property page is destroyed.)
Before doing the propsheet.Domodal(), you initialize all member variables of the property pages.
When the user clicks OK, the property sheet object still exist, and so do the property pages. You can then retrieve the data from the prop pages member variables.
A small code snippet:
CPage5Dlg page5;
page5.m_EnvList =m_EnvList;
page5.m_psp.dwFlags &=~PSP_HASHELP;
page5.m_AllowMultisession=m_AllowMultisession;
page5.m_AppendProject=m_AppendNewProject;
page5.m_psp.dwFlags| =PSP_USETITLE;
page5.m_psp.dwFlags& =~PSP_HASHELP;
page5.m_psp.pszTitle ="Environment";
CPage3Dlg page3comp;
page3comp.m_ShowLog=m_ShowCompilerLog;
page3comp.m_ShowComp=m_ShowCompilerWindow;
page3comp.m_CheckInno=m_CheckInno;
page3comp.m_DoComp=true;
page3comp.m_strarrNames.Copy(m_strarrNames);
page3comp.m_strarrOpt.Copy(m_strarrOpt);
page3comp.m_psp.dwFlags|=PSP_USETITLE;
page3comp.m_psp.dwFlags&=~PSP_HASHELP;
page3comp.m_psp.pszTitle="Compiler";
CPropertySheet Hello;
Hello.SetTitle("Settings...");
Hello.m_psh.dwFlags&=~PSH_HASHELP;
Hello.m_psh.dwFlags|=PSH_NOAPPLYNOW|PSH_USEHICON;
Hello.m_psh.hIcon=m_hIcon;
Hello.AddPage(&page5);
Hello.AddPage(&page3comp);
if (Hello.DoModal()==IDOK)
{
m_EnvList = page5.m_EnvList;
m_NamesArr = page3comp.strarrOpt;
}
~RaGE();

Just making my first steps in DLL and wanna see a very simple example of loading DLL by using function LoadLibrary or DEF files.My DLL is kinda of simple math library for adding ,substracting ,...but dont know how to load it by using LoadLibrary or DEF.Best Regards

HINSTANCE hinstLib;
hinstLib=LoadLibrary("Path to the dll");//replace with your path to the dll
CreateFn pfnCreate = (CreateFn) GetProcAddress((HINSTANCE) hinstLib, _T("Yourfunction"));// replace YourFunction with// function name
FreeLibrary(hinstLib);
Does this solve your problem
Wishes.

Can anyone help?
If there is an array has be randomly generated, and its size is in the range 2 to 5, how can I swap the h with the other elements as I dont know the exact location of the others at the beginning?
C | A
B | h
In the above case, am I wrong if I hit 4 at the keyboard to swap h with B, hit 8 to swap h with A, and hit 7 to swap h with C?
