Re: Is there a way to keep the mouse from moving...

MSDN:
The BlockInput function blocks keyboard and mouse input events from reaching applications.

That basically means that no input is received until (if you read further) the blocking state is removed by calling the function again. So the message that he is waiting for (the WM_LBUTTUNUP) or the messages that the mouse is moving into the other direction, don't arrive either.

So basically he disables the entire app and starts waiting for an event that will never arrive...

I wonder if that functionality does not depend exclusively on the graphic driver, and is not part of the Windows API. Should it be true, you have no chance to write such an application, without using the API of the driver (if exists!). But perhaps someone else can confirm/contradict my guess.

I'd say you were overloading this function, but you deleted the body and the macro in the header file is still there.

Looks like you deleted your OnInitialUpdate function in the view class (CMyAppView), but didn't delete the declaration from the header file.

Are you using GDI+ ? You're trying to get the DPI settings for an image, or from a printer ?

Right click and choose add project. Right click on the project you want to run and choose 'make this the default project'.

Something like that. More specific instructions would require knowledge of the version of the IDE you are using.

I don't think you can do that, you can however add more projects to your solution / workspace the way Christian explained.

EnableMenu() not working

Member 19839859-Jun-05 15:00

Member 1983985

9-Jun-05 15:00

I have to be doing something wrong as this is too simple. I have a doc/view project with a LOT of menu items. EnableMenu() isn't working as I want it to. However, I can call the CheckMenuItem member and it works fine in the same SPOT!

This code takes a emumerated list of ALL menu items and checks each menu item. It works perfectly:

<br />
CMenu* pMenu = GetMenu();<br />
<br />
// this checks each menu item (note ID_SEPARATOR is the last in my enum)<br />
for(int i = 0; mymenuids[i] != ID_SEPARATOR; i++)<br />
   pMenu->CheckMenuItem(mymenuids[i], MF_CHECKED);<br />

Now, if I change this to gray all the entries, NONE of them gray\disable:

<br />
CMenu* pMenu = GetMenu();<br />
<br />
// this disables each menu item (note ID_SEPARATOR is the last in my enum)<br />
for(int i = 0; mymenuids[i] != ID_SEPARATOR; i++)<br />
   pMenu->EnableMenuItem(mymenuids[i], MF_BYCOMMAND | MF_DISABLED | MF_GRAYED);<br />

What could possibly be wrong? Possible that a resource file has corrupted? I'm baffled!

Thanks in advance,
Philip
