That is because your project properties are different for the debug and for the release version (all the properties are completely different for the several versions). Just disable use compiler header in the settings.
For VC2005, go into project properties -> 'C/C++' -> 'Precompiled Headers' -> choose 'Not Using Precompiled Headers' in 'Use Precompiled Headers"

Yes, it is illegal  . You cannot distribute the debug version of the microsoft dll's. It contains some debug information and thus cannot be distributed.

Hi Cedric
Thanks for your advice
Just done this in VC++ 6.0. It took a bit of digging to find the pre-compiled header settings , but I got there! Deselecting this resolved this issue (introduced other though, which I have now fixed) and heh presto, got my release version.
The size is a 1/4 of the debug version. Does a 'Release' version run faster than a 'debug' version?
Thanks for your help

Normally yes but in general it is not really noticeable. Except if you do some heavy computing, then the difference is obvious.

Most of the time when you forget to include your precompiled header file then you get this rather cryptic message.

No, but keep in mind that you cannot distribute the debug version of the DLLs (e.g., msvcrtd.dll). Have you considered statically linking with the libraries?

Hello,
I would like to display a small icon in a dialog box.
For this, I use an icon control, i.e. a static control with the styles SS_ICON and SS_CENTERIMAGE. I then load the small icon and associate it with the static control using the following code :
int cx_smicon = ::GetSystemMetrics(SM_CXSMICON);
int cy_smicon = ::GetSystemMetrics(SM_CYSMICON);
HINSTANCE hInstance = g_hInstance;
if (szResource == IDI_WARNING ||
szResource == IDI_ERROR ||
szResource == IDI_INFORMATION)
hInstance = 0;
HICON hIcon = (HICON) ::LoadImage(hInstance
, szResource
, IMAGE_ICON
, cx_smicon
, cy_smicon
, LR_SHARED);
::SendDlgItemMessage(hWnd, IDC_ICON
, STM_SETICON
, (WPARAM) hIcon
, (LPARAM) 0L);
The above code displays custom icons correctly (with the desired size 16x16) but standard icons are always displayed using the standard size 32x32.
I don't understand what I'm doing wrong.
Have someone already encountered this problem ?
Thanks for your help.

Are you supposed to use LR_SHARED with images loaded from a file?

When I use VC6.0,I find that:
float value=33.4;
DWORD temp=33;
value=value-(float)temp; or value=value-temp;
Then value will be 0.4 in theory. But in face it is 0.400002 in vc 6.0.
Why is it? is it a bug of VC6.0 or CPU?

Because,in fact,the float or double is not always preciously number when it store in the memory.
|
|

That's life with floating point arithmetic. Just like 1/3 can't be represented in decimal without an infinite number of decimal places not all numbers can be represented exactly in base 2 with a fixed number of binary places.
If you use doubles to get more precision the answer comes to 0.39999999999999858 which is closer to the ideal.
On a sererate issue, lose the float cast: it's not needed and is bad form.

Hi~~~ I have a question about Clipboard.
WM_DRAWCLIPBOARD message is notified when the clipboard data is changed.
Then how do I sniff that the message of paste is sent to clipboard??
Please help~~~

I dont think it is possible as the paste operation shud be strictly b/w the paster and the pastee. As for copy and cut they are notified as the clipboard is a common data repository for all the applications and seriously i fail to understand the usage.. anyways if someone know anything about this enlighten me too!

What is wchar_t used for? How can I create a wchar_t string?

Daniel Kanev wrote: What is wchar_t used for
A variable of __wchar_t designates a wide-character or multibyte character type. By default wchar_t is a typedef for unsigned short.

Use the L prefix before a character or string constant.

wchar_t is a keyword in C++ and is used to designate wide-character type(not multibyte).
In VC7 there's an option to set whether to treat wchar_t as a built-in type or unsinged short.

I Checked this out from MSDN.
The exact lines are:

Yes I have read about it. It's also mentioned in MSDN.

For Example,When you want to process Chinese font,you have to chose the wchar type in your programer.

The STL class wstring deals with wchar_t's. You can use it just like you would the string class (with the wide versions of other STL classes, that is).

keep a pointer of the list box in the first dialog( dialog which have the edit box). Then on pressing the button call the AddString function of that pointer.

You may right the interface function for setting the value in the second dialog
On the button click of first dialog
{
Dlg->SetDataToListBox( m_Edit.GetWindowText()); //Where Dlg is the second dialog class object
}
In the second dialog
2ndDlg::SetDataToListBox( CString EditData ) // SetDataToListBox function the dialog class of the second dialog
{
m_ListBox.AddString( EditData );
}

You can take the text of the edti box on the click of the button using the GetWindowText.
For list control you can then use CListCtrl::SetItemText()which Changes the text of a list view item or subitem.
BOOL SetItemText(
int nItem,
int nSubItem,
LPCTSTR lpszText
);

For List box you can use
CListBox::InsertString() / CListBox::AddString()
