It is the property of MFC,
MFC disables controls if the handlers is not available
override OnUpdateCmdUI() this will enable all.
But MFC wants handlers for each control

Now you have your CYourDlgBarClass,
using class wizard add the override OnUpdateCmdUI(), that's all, this will add

virtual void OnUpdateCmdUI(<br />
       IN CFrameWnd* pTarget, <br />
       IN BOOL bDisableIfNoHandler<br />
       );

in your declaration
and

<br />
void <br />
CYourDlgBarClass::OnUpdateCmdUI(<br />
	IN CFrameWnd* /*pTarget*/, <br />
	IN BOOL /*bDisableIfNoHandler*/<br />
	)<br />
{<br />
	// TODO: Add your specialized code here and/or call the base class<br />
}<br />

in your implementation
if class wizard found to be not helpful, simply code manually,

this is enough to enable.

for enabling individual controls ,
use
ON_UPDATE_COMMAND_UI(id /* control id*/, memberFxn ) in the message map.

1) No it can be found in class wizard, I donot have issue in VS2005,
2) The default implementation will disable it, we overrided it.
3) IN is simply a empty macro, used just for code readability,
(the parameter is input that is caller donot expect change, there is also OUT macro).

You need to use DockControlBar() with all parameters set to customise the order of docking.

Remove these codes of your program

SetIcon(m_hIcon, TRUE);			// Set big icon
SetIcon(m_hIcon, FALSE);		// Set small icon

I think WhiteSky meant to set the icon handles to NULL Smile | :)

::SendMessage(hwnd, WM_SETICON, ICON_BIG, (LPARAM)0);
::SendMessage(hwnd, WM_SETICON, ICON_SMALL, (LPARAM)0);

or with MFC

SetIcon(NULL, TRUE); // Set big icon
SetIcon(NULL, FALSE); // Set small icon

Is the dialog window a client of another frame window?

What are all the window styles and extended styles you use when you create the dialog?

:->Some software,after you have installed,can open assiociated files just double click it.How to do that or how to write the code.I will be very thankful if somebody give me a little information or some code samples would be better.

Hi,
Simply you need the following information on the system registry,

HKEY_CLASSES_ROOT\.<fileextension> "<yourFriendlyName>"

HKEY_CLASSES_ROOT\<yourFriendlyName>\Shell\Open\command "<yourApplicationPath>"
HKEY_CLASSES_ROOT\<yourFriendlyName>\DefaultIcon "<yourApplicationIconPath>"

How to,
1. MFC will do for this using Doc/View Architecture
2. In Win32 you can use registry APIs
3. You can manually edit registry using regedit

1)My application is Dialog based. Then you mean that MFC will not do it for me automatically?
2)I think my application can not open the file directly. It only open the file with its menu item "Open File". Maybe I need to write a main() function to open the file in command line just like Java. But I am not very sure how does this main function really look like.

Thanks for your attention.

Hi,
I think your query was to associate the file type with your application so that windows will create your application instance when the file is double clicked.

I hope this link provides coding information for associating file types.
http://www.codeproject.com/shell/cgfiletype.asp[^]

What is your problem, do you want to associate file type or want to get file names from command line.

Correct. So why not just create an SDI project to see what type of .reg file it puts together? Then you'll know exactly what to put in the registry for your dialog-based application.

Assuming you need to do that, use atoi to convert.

In that case, the string need to be in decimal representation, not in binary representation.

Take a look at strtol[^]. You can provide 2 as the basis and it will convert your string representing a binary into a long. Then you just perform logical operations on your long (&& for AND, || for OR, for XOR I don't remember what it was but you can make an OR and then invert the result with !).

Hi Shah,

Following routine should do the job:

int StrToBinary (LPCTSTR szString)
{
int nBit = 1;
int nResult = 0;
int i;

i = strlen (szString);
while (i > 0)
{
if (szString[--i] != '0')
nResult |= nBit;
nBit *= 2;
}
return nResult;
}

Good luck
William
