It does. You can add menu/toolbar item message handlers to your document class. MFC has some internal magic that will route it to the document's handler if the view doesn't process the message.

Ｉuse Administrator to Logged on My widnow xp.
I enum the share printer connected in the network.
I use openprinters() to open the printer ,it success.
I get the printer handle.
then I use FindFirstPrinterChangeNotification() to Monitor the printer ,it fail ,the Error code is 5(ERROR_ACCESS_DENIED).
but if Use the domain user to logged on my window xp(just like: domain1\\user1),
all is good .
why?
what different between of administrator(local) and domain1\\user1(domain)?
how to fix it?
thanks!
my code like this:
hPrinterNotification = FindFirstPrinterChangeNotification(
ThreadParam.hPrinter,
PRINTER_CHANGE_DELETE_JOB,
0,
&NotificationOptions);
if (hPrinterNotification == INVALID_HANDLE_VALUE)
{
CString strE;
strE.Format ("FindFirstPrinterChangeNotification failed! Error code = %d",GetLastError());
return 0;
}

Your local administrator account does not necessarily have privileges on the network.
It is possible to enumerate network resources without having necessary permission to access or utilize those resources.
So, you can enumerate the printers, but when you try to open one, you fail from the local administrator account. Your domain account obviously has network printer privileges.

Blake Miller:
can you tell how to open one from the local administrator account?
thanks!

The same way you open the other ones, but you have to be granted access permission form the owner of the object, in this case the printer.
In other words, a network administrator needs to grant the MachineName\Administrator account privileges to modify the printer.
Also, you could try different access permission request, instead of ALL_ACCESS try something like 'read' access rights on the OpenPrinter command, that might work, since you are perhaps not trying to change anything.
Most people seem to go for ALL_ACCESS when they only want to query a device. Opening for read only access often works where 'all access' or 'write access' requests fail.
You could post the code for your OpenPrinter command and me or someone here could try to help you out.

Does anyone know why a c++ mfc exe would run without displaying it's form?
Unfortunately I don't have the source.
|
|
|
|
|
check in the property from Dialog that Visible is ture
|
|
|
|
|
i can't do that as i don't have the source code. I'm sure however that the visible property would be true as the app was built to display a form. It's some sort of environment issue i think.
|
|
|
|
|
So I think in the source code use ShowWindow(0)
|
|
|
|
|
i don't have the source code
|
|
|
|

It might be displaying the form off screen. You can use Spy++ to see the properties of the window the process creates and see whether it is visible, and what its position is.

Im populating the CCombox on OnInitDialog.
How to put color on each item text so when the user click the combobox, it will list the items in color (i.e. half of the list is red and half of the list is blue)
|
|
|
|
|
You have to set the Combobox style to CBS_OWNERDRAW. Then you must draw the Combobox items when the window passes the WM_DRAWITEM message.
|
|
|
|
|
Here[^] is a demo.

First derived from CComboBox
and use WM_DRAWITEM then you should set DC in the combobox
Like this:
void CMyComboBox::DrawItem(LPDRAWITEMSTRUCT lpDrawItem)
{
CDC dc;
dc.Attach(lpDrawItem->hDC);
....
....
if ((lpDrawItem->itemAction | ODA_SELECT) &&
(lpDrawItem->itemState & ODS_SELECTED))
{
...
...
...
}
else
{
...
...
}
dc.DrawText('item text', -1, &rect, DT_LEFT|DT_SINGLELINE|DT_VCENTER);
dc.Detach();
}
And you can use OnCtlColor in this Class.

I have been programming windows using C++ since a year, but havent done any UI programming. Now I need to get into UI development, I would like to know of any introductory articles in this area. I have not used MFC before, and would like to stay away from it if possible. Can people suggest any URLs on UI development using C++ that can get me started?
thanks!

Why don't you try working on SDK.
This is a slow process for developing an application , on the other hand if you use MFC you can speed up application development. You can read the code from this site for developing SDK applications
Vision is Always important and so is your ATTITUDE.

See the documentation that is available for SDK on codeproject.com.
You will see the option for SDK in the left hand pane when you scroll down on the login page

If you right click the CD/DVD-ROM, it will show a menu, and one of its menuitem is "eject". As everyone know that all menuitem have an ID, but after tracing the code, I found that the ID of "eject" can be 31014(normal),
30757(folder view), 47(tree view while using folder mode), 31078(short cut),
102(quick launch view), 38(tree view in the application of winrar), 39(create toolbar on taskbar). And i don't if this menuitem ID have other value. Could somebody help me? How to compute the ID or how many ID are there leave for this menuitem of "eject"??

What would you like to do with that ID. To eject the CD/DVD drive you have to call functions. The ID is useless because every programm has its own menu-IDs for perhaps similar commands.
|
|
|
|
|
I want to control the flow of eject action! when user click eject, it will get into my code, then i can control it.So i must modify the menuitem, there are two flag can be used, MF_POSITION and MF_COMMAND, it seems that is impossible to get the position of eject, so i choose MF_COMMAND, but i have to get the ID.

WM_DEVICECHANGE should help you.

It seems to be impossible. How I told you before: every application can use its own ID for the eject command. The usage of a command is hard encoded in its program-code. Therefore its no way to find out which command executes the eject function.
The other post told you about the WM_DEVICECHANGE message - but this is only a notification message broadcasting to all toplevel windows. This message informs all windows that a device has been changed (see Windows-SDK for help).
I've just tested the WM_DEVICECHANGE: the message is called after the media has been removed.
#include <DBT.H><br />
void CFrame::WmDeviceChange(WPARAM w,LPARAM l)<br />
{<br />
switch(w)<br />
{<br />
case DBT_CONFIGCHANGECANCELED:<br />
break;<br />
case DBT_CONFIGCHANGED:<br />
break;<br />
case DBT_DEVICEARRIVAL:<br />
break;<br />
case DBT_DEVICEQUERYREMOVE:<br />
break;<br />
case DBT_DEVICEQUERYREMOVEFAILED:<br />
break;<br />
case DBT_DEVICEREMOVECOMPLETE:<br />
break;<br />
case DBT_DEVICEREMOVEPENDING:<br />
break;<br />
case DBT_DEVICETYPESPECIFIC:<br />
break;<br />
case DBT_USERDEFINED:<br />
break;<br />
default:<br />
TRACE("WmDeviceChange: 0x%04X\r\n",w);<br />
break;<br />
}<br />
}
