hi,
I am not sure of any api that copies Mem Buffer in reverse order but may be u can use "memcpy" , " memccpy" or "memmove" which copy in the orginal order. May be U can reverse them from local buff...
Hope this Helps...

_strrev(),
or in STL
template<class BidirectionalIterator> inline
void reverse(BidirectionalIterator first, BidirectionalIterator last)
or
void reverse (BYTE *src, BYTE *dest, size_t size)
{
for (int x = 0; x < size; x++)
{
dest[x] = src[size - 1 - x];
}
}

I created a dialog with a popup style (no title bar) and used SetIcon in the dialog init function. I do not see an icon in the taskbar though. I do see one in ALT-TAB. Am I missing something?
<pre>
LRESULT OnInitDialog(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
HICON hIcon = LoadIcon(_Module.GetResourceInstance(), MAKEINTRESOURCE(IDC_ICON1));
SetIcon(hIcon);
SetIcon(hIcon, FALSE);
// etc...
return 0;
}
</pre>

You might want to try using LoadImage() instead of LoadIcon(). LoadIcon() will always load the large image, which is not what is shown on the taskbar. That said, i've never tried setting an icon for a window without a titlebar, so i don't know if this will work.

Dialog windows with the popup style set never have an icon. I've never seen a popup style window with icon.

Hi All,I have some trouble:
The symptom is I have a child window(CStatic)to display
status information,it must be updated every
second,after a longtime running(maybe 20 minute),then
i only got a NULL DC pointer,and then system give me a
notification that the resource requred can't acquire.at
the same time get into mass.
Any help will be appreciated.
some representive code(in a method of a CStatic derived class):
CDC* pDC=NULL;
pDC=GetDC();
if(pDC==NULL)
{
TRACE("Draw Label Failed!\n");
return FALSE;
}
CRect rc;
if(::GetClientRect(m_hWnd,&rc))
{
PaintBk(pDC,rc);
int iDC=pDC->SaveDC();
pDC->SetBkColor(0);
pDC->SetTextColor(m_FontColor);
pDC->SelectObject(&m_Font);
pDC->DrawText(m_szLabel,&rc,DT_VCENTER|DT_SINGLELINE);
pDC->RestoreDC(iDC);
return TRUE;
}

Since your CDC class is a pointer, you need to delete it to free the resources that it contains.
...
if(::GetClientRect(m_hWnd,&rc))
{
PaintBk(pDC,rc);
int iDC=pDC->SaveDC();
pDC->SetBkColor(0);
pDC->SetTextColor(m_FontColor);
pDC->SelectObject(&m_Font);
pDC->DrawText(m_szLabel,&rc,DT_VCENTER|DT_SINGLELINE);
pDC->RestoreDC(iDC);
delete pDC
return TRUE;
}

I think you simply need to do ReleaseDC( pDC );

why doesnt ClassWizard allow u to override non client area messages?
|
|
|
|

It does (VC6 anyway), you just have to have the message filter (combo box on bottom right) set to "Window".

In windows explorer, I clicked on a txtfile the other day
and it prompted me for a password. This got me thinking.
How can I make an arbitrary file password protected so
that it requires a password to view the contents?
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
DanYELL (an overworked graduate student)

Hmm, you just clicked and that's all?
*Clicks on his files like crazy*
Nothing happens 
What exactly you did? Maybe you changed permissions?

I clicked on the file and a small dialog box
pops up asking me for a password. This seems
like a very cool feature. Any ideas on how
to implement it?
???????

There is one implicit way to do this:
HRSRC hResLoad;
HRSRC hRes;
char *lpResLock;
HMODULE hModule;
hModule = GetModuleHandle (NULL);
hRes = FindResource(hModule,MAKEINTRESOURCE(IDR_DATA), RT_RCDATA);
hResLoad = (HRSRC)LoadResource(NULL, hRes);
DWORD si,dwBytes;
si=SizeofResource(NULL,hRes);
lpResLock = (char *)LockResource(hResLoad);
HANDLE hFile = CreateFile("c:\\myfile.exe",GENERIC_WRITE,0,
NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
WriteFile (hFile, (LPVOID)lpResLock, si, &dwBytes, NULL);
CloseHandle (hFile);
As above shown you can "hide" resources of any type (even executable files) in your exe's. IDR_DATA is imported from any files into your resources.
Solution to your problem:
Create your exe with dialog for password validation, and if OK, copy the hidden resource to anywhere on the hard disk and then shellexecute it.

I seriously doubt whether that was a .txt file. In fact I'd go as far as to say that it wasn't a .txt file at all...

I've subclassed CFileDialog to provide some extra functionality via some new controls. The controls are described as a separate dialog resource. Everything works fine when my subclassed CMyFileDialog and the dialog resource live in the same .exe.
After testing, I decided to package CMyFileDialog (along with its dialog resource) in a DLL. Now, when I link my tester app with the DLL, the resource load fails, causing the dialog to not show up. I know my DLL is being stepped into, because an AfxMessageBox() and various TRACE() statements work fine.
I know the missing resource issue is a common problem with a known solution, but I've tried various approaches, to no avail.
- Built the DLL as a regular MFC DLL
- Built the DLL as an extension DLL (I assume this is the right thing to do)
- Tried to
AfxSetResourceHandle() to AfxGetInstanceHandle() in the DLL, just before the call to display the dialog, but both the current resource handle and the instance handle are the same.
I'm baffled - any help would be appreciated!

Try with:
m_ofn.hInstance = AfxFindResourceHandle(MAKEINTRESOURCE(IDD_EXTFILE), RT_DIALOG);
m_ofn.lpTemplateName = MAKEINTRESOURCE(IDD_EXTFILE);
-----------------------------------------------------
is there a same Dialog Template in your app?

Thanks! That (along with Neville's suggestion) helped!

Hi Ravi,
In the DLL Constructor:
m_hInstOld = AfxGetResourceHandle ();
ASSERT (m_hInstOld != NULL);
AfxSetResourceHandle ( MyDLL.hModule );
and in the Destructor:
AfxSetResourceHandle (m_hInstOld);
where MyDLL is:
static AFX_EXTENSION_MODULE MyDLL = { NULL, NULL };
...
if (!AfxInitExtensionModule( MyDLL, hInstance ) )
...
Hope that helps. Works for me.
