This is the best way:

<br />
BEGIN_MESSAGE_MAP(CYourFrame, CMainFrame)<br />
	ON_UPDATE_COMMAND_UI(ID_MENU_ITEM_1, OnUpdateMenuItem1)<br />
END_MESSAGE_MAP()<br />
<br />
//*******************************************************************************************<br />
void CYourFrame::OnUpdateMenuItem1(CCmdUI *pCmdUI)<br />
{<br />
  pCmdUI->Enable([TRUE or FALSE here depending on condition]);<br />
}<br />

Hope it helps

How to select a folder path in MFC?

Hello, I tried to use CFileDialog to choose a folder path in my program but it this way user has to select a file and then I have to use GetFolderPath() to get the path but it may not be very sensible to user to select an arbitary file within a directory to select that directory on the other hand the directory can be empty that creates an additional problem. How can I open a dialog so user can select a folder path? is it possible to select from a tree structure of directories?
Thanks

Did you have a look at SHBrowseForFolder API.
It returns a pointer to an item identifier list (PIDL) specifying the location of the selected folder relative to the root of the namespace.

Somethings seem HARD to do, until we know how to do them.

Thanks alot _AnShUmAn_, though I have programmed for more than four years with MFC I still do not know some APIs and when I looked in help with keywords: "choose folder" it returned nothing useful. you helped me a lot god bless you.

FYI, SHBrowseForFolder is not MFC, it is part of the Windows API - Windows Shell programming, to be specific

Hello All,

Actually i am using in my application "PropertyPage and PropertySheet" so i have to set bitmap on PropertySheet header and footer for every page so for that i am trying as follows:

constructor of my propertysheet class

CMyPropertySheet::CMyPropertySheet(CWnd* pParentWnd,
UINT iSelectPage, HBITMAP hWatermark, HPALETTE hpalWatermark,
HBITMAP hHeader)
: CPropertySheet(what i have to give caption ID here, pParentWnd, iSelectPage, hWatermark, hpalWatermark, hHeader)

and i am calling that as follows:
Bitmap bmWatermark;
CBitmap bmHeader;
if(!bmWatermark.LoadBitmap(IDB_BITMAP1))
return FALSE;
if(!bmHeader.LoadBitmap(IDB_BITMAP1))
return FALSE;

CMyPropertySheet MyPropSheet(NULL, 0, bmWatermark, NULL, bmHeader);

for this i am only unable to understand what i have to caption id into CPropertySheet(....) constructor if i am giving some integer than it got crashed

so if anybody have idea please share with me..........

thanks

The ID would be a resource ID of the string resource to use as a caption.
There's also a constructor that takes a LPCTSTR so you could pass something like _T("My Caption").

Passing threa point in different dialog

I have a class derived from CWinThread, which have a CWnd* member which would recieve message from the thread. In the class also has a socket member,it would send network message to the CWnd* member.

I use such class in a Dialog,it works well.But when the main dialog create a new child dialog and show it using DoModal() function, and I want to make the child dialog correspond to the thread message and network message. In the child dialog,I send data to somewhere,but the class does send the data when the child dialog closed. Why?
Thanks

Good Luck.

I don't completely understand what you're doing but...

The window used for socket notifications doesn't have to be a visible window that the user can
interact with. It does, however, need to be created on a thread that has a message loop (your
CWinThread will provide that). If you create the window/dialog on another thread than your
CWinThread then it's possibly not going to work.

I am trying the example of this web quote: http://www.flounder.com/kb192570.htm[^]

It really works well.but wen I using the ClientThread in another dialog,such problem occur.
I do not know why

Does it work if the dialog is modeless?

It works well when there only one dialog.
If create a model dialog,the data you sent in the new dialog did really be send when the new dialog was closed

I'm not sure if it will work in a modal dialog.

If you're using sockets notifications to a window then that should be in one place.
You should be able to leave it in your main window.dialog.

I'm not sure completely how Mr Newcomer implemented his socket notifications in the article
you referred to. It may not work in a modal dialog. In general, a modal dialog is a bad place
for this kind of thing.

I think the thread or the socket would be blocked during the second dialog is active,perhaps.
But,if it so,I want to know,if is a modeless dialog,the socket and the thread would not be blocked?
In fact,the socket was create and connect to the server in the initialize function of the thread.So,I want to using the same socket so that it would not be created and connect to server again.
Would you like to tell me,how to resolve my aim or such problem?
Thanks.

Best Wishes

Hi you are a bit missing.
Video recording/playing is a job of DirectShow.
which was a part of DirectX but now part of
Windows Platform SDK

You can see my projects on the codeprojects about
DirectShow or my site Totally dedicated to DirectShow

Hi You will have to download the windows platform SDK.
DirectShow is part of it.
It is enough for your work.
