yes in this case it will work
as char *str1!= char *const str1
never say die

sprintf(str1,"The Sum is %d",Add(10,20));
I think an exception will be raised coz str1 is just a pointer and no memory allocated for the result to be stored.

Are you sure you did this:
#include <tchar.h>

Hello; Thanks for all. I got the solution.
------------------
Previous code is
#include < tchar.h >
#include < stdio.h >
#include "stdafx.h"
Which is wrong.
------------------
Present code is
#include "stdafx.h"
#include < tchar.h >
#include < stdio.h >
Which is correct.
------------------
Oh. Sorry for my mistake  and Thanks for All.
Advance  Happy new year to all
Nice talking to you.

hi,
can anyone tell me how to make a dialogbox (modal and non modal) fade in ?
I have heard that you can do it with AnimateWindow(), but there is not much code around and MSDN isn't helping much either.
thanks for the replies in advance

Use it in place of ShowWindow(...).
That's what they say...;)

well, if you are meaning something like this :
CMyDialog *dlg;
dlg=new CMyDialog;
dlg->Create(IDD_MAINDIALOG,NULL);
then
dlg->AnimateWindow() is not a member. Its a member of CWnd.
On the other hand, I had a look at Shog9 's code at http://www.codeproject.com/miscctrl/balloonhelp.asp[^] and did the following:
made the following addition in my .h file :
private:<br />
typedef BOOL (WINAPI* FN_ANIMATE_WINDOW)(HWND,DWORD,DWORD);<br />
FN_ANIMATE_WINDOW m_fnAnimateWindow;
made the edition in the default constructor as :
CMyDialog::CMyDialog(CWnd* pParent )<br />
: CDialog(CMyDialog::IDD, pParent),m_fnAnimateWindow(NULL)
and changed the WM_SHOW like this :
void CMyDialog::OnShowWindow(BOOL bShow, UINT nStatus) <br />
{<br />
if ( NULL != m_fnAnimateWindow )<br />
{<br />
<br />
m_fnAnimateWindow( m_hWnd, 200, AW_BLEND);<br />
<br />
}<br />
}
now I get no compiler errors, the window shows, but no animation

OK i have figured it out, the problem was AW_BLEND. it don't work with child windows. I used AW_CENTER and it worked fine, but now the 2nd hurdle.
I have used bitmapped background and controls and they appear messed up.
any ideas what to do?

Make sure you set the bitmap background in the message handler for
WM_ERASEBKGND.
And if you are doing your own background painting return a NON-ZERO value.

Ok.. My Pleasure .. kiddin.. Use AnimateWindow in OnInitDialog Function like this :-
BOOL CAnimateWndDlg::OnInitDialog()
{
CDialog::OnInitDialog();
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
::AnimateWindow(this->GetSafeHwnd(),5000,AW_BLEND);
return FALSE;
}

I use the following code in a function that allows the animations to be random. I call it in OnInitDialog() (and I think I also used it when closing the dialog).
void [ClassName]::AnimateDialog(HWND hWnd)
{
DWORD dwTemp2,dwTemp,dwAnimate = AW_ACTIVATE;
int nFirst,nSecond;
srand( (unsigned)time( NULL ) );
nFirst = rand() % 3 + 1;
switch(nFirst)
{
case 1:
dwTemp = AW_SLIDE;
break;
case 2:
case 3:
dwTemp = AW_CENTER;
break;
}
dwAnimate |= dwTemp;
if(nFirst == 1)
{
srand( (unsigned)time( NULL ) );
nSecond = rand() % 4 + 1;
switch(nSecond)
{
case 1:
dwTemp2 = AW_HOR_POSITIVE ;
break;
case 2:
dwTemp2 = AW_HOR_NEGATIVE;
break;
case 3:
dwTemp2 = AW_VER_POSITIVE;
break;
default:
dwTemp2 = AW_VER_NEGATIVE;
}
dwAnimate |= dwTemp2;
srand( (unsigned)time( NULL ) );
nSecond = rand() % 2;
if(dwTemp2 == AW_VER_POSITIVE || dwTemp2 == AW_VER_NEGATIVE)
{
dwTemp2 = 0;
switch(nSecond)
{
case 1: dwTemp2 = AW_HOR_POSITIVE; break;
case 2: dwTemp2 = AW_HOR_NEGATIVE; break;
}
dwAnimate |= dwTemp2;
}
else
{
dwTemp2 = 0;
switch(nSecond)
{
case 1: dwTemp2 = AW_VER_POSITIVE; break;
case 2: dwTemp2 = AW_VER_NEGATIVE; break;
}
dwAnimate |= dwTemp2;
}
}
::AnimateWindow(hWnd,200,dwAnimate);
}
But as you can see, I had problems with the fade myself. However what I did for a dialog that I wanted to fade was call SetLayeredWindowAttributes() in a timer event that made the small dialog fade in and out like an Outlook mail notification.

Hi all:
I started a VC/SmartDevice project under VC 7.0, But the CFile class seems don't works, I wonder is it because of the specific project I choose?
The innocent statement like:
CFile file;
if ( ! file.Open( _T("C:\\Test.txt", CFile::modeRead ) )
{
return;
}
is always invalid, the if statement always evaluate to TRUE
|
|
|
|
|
firstly it is
if ( ! file.Open( _T("C:\\Test.txt"), CFile::modeRead )
The file C:\Test.txt should exist.
I belive it is also throwing a CFileException exception I am not sure about the device version, but if it throwing, then you should catch the exception and examine on what the api is complaining about.

if ( ! file.Open( _T("C:\\Test.txt"), CFile::modeRead )
may be the closing bracket around the absolute file path is not placed correctly

Hi,
I am developing a shell namespace extension which will be loaded by explorer.exe. Since I have implemented file uploading in a seperate queue, I couldn't unable the dll even if the reference count becomes zero. For that I am always returning S_FALSE from DllCanUnloadNow method.
The problem is, If someone wants to install a new version, since the dll is in memory and couldn't be unloaded I am not able to overwrite the new version. Is there any mechanism by which I can forcefully unload a dll ?
I recollect reading an article which suggests returning S_OK from DllCanUnloadNow depending on the application which is trying to unload the dll. But I couldn't find the link even after gooogling for hours.
Any help on this would be greatly appreciated!!!
Merry X'mas and Happy New Year.
Thanks and Regards
