I have developed an MFC application which reads data from a Joystick (x, y, z and 4 buttons).
All the data regarding the joystick is displayed on the dialog.
However what I would like to do is convert this Joystick EXE into a DLL with some functions calls to access the Joystick data. This would allow other applications to obtain the Joystick data.
What I did not want to do was include all the bits required (from the original MFC Joystick application) into any applications that needed the Joystick information.
Now my question is can this Joystick MFC application be converted into a DLL; can you include function calls to make the dialog visiable or hidden as required from the EXE applications that use this DLL.
i.e. are they any limitations on the DLL that I have to take into account. The Joystick code uses Windows Messages JOY1MOVE, JOY1BUTTONUP etc and timers.

Definitely. Check out MFC extension DLL.

i have a list box,edit box and a button named add.
The problem is the code i wrote for the add button which takes the string entered in the edit box keeps it in the list box.
My problem is when i double-click on a item in the listbox,i should be able to edit that string and when i am done,the new string should be there instead of the previous one.
How can a listbox get the properties of an edit box?
ASAP!!
thanx

Ok, so what's the problem/question? Why not provide a code snippet that can be critiqued?

I have a small contract to slightly alter a piece of software that I own to adapt it to the needs of a client. Does anyone know if there is any precedent for who by default has the intellectal property in this case? Would I have to specify this in the invoice that it in no way represents a transfer of IP if I wanted to keep control of the software even after the modification were made? The client is in Europe.

My guess would be that they would own the rights to the modification, but not the core component.

Unless otherwise stipulated, you would likely retain ownership of the intellectual property. For safety, however, you should create a contract that clearly specifies this.
(If the creative forces reside in the contractee and you work exclusively for them, even if a contractor, the work would likely be classified as "work-for-hire" and the contractee would own the copyright and intellectual property, but that doesn't sound like your situation.)
Also be aware that any translations are copyrighted separate from the code by the translator. Be sure you get a signed contract assigning copyright back to you in this case.

I'm wondering about a behaviour with MFC application on a CDialog concerning the mnemonic.
I always thought that an object(e.g. a CButton)'s
function is executed when pressing ALT+Mnemonic.
Now I saw that the function is executed if the focus is in a non-entry control (like a CButton) without pressing the ALT key.
Is there a chance to avoid this behaviour and only execute the function by using ALT+Mnemonic?
|
|
|
|
|
I'm not a 100% sure but I think this is the default behaviour
if the focus is set to a non-edit control.
Maybe you can change this behaviour by overriding PreTranslateMessage,
but I am only guessing...

Does 'EnumDesktopWindows' is not supported in windows 95/98 ?
If not - How else can i get a handle to the windows currrently running ?

Correct, it is not supported on those platforms.

Please indicate what problem you are attempting to solve, and we might be able to offer a solution that does not depend on EnumDesktopWindows().

I am trying to write a browser monitor. If i could get a handle to the current open windows then I can decide whether it is a browser , if it it - then look on the window control to look for the site that is currently being viewd.

It would be much easier to write a Browser Helper Object (BHO). There are examples here at CP. You can also Google for more.

Hi all,
I would like to be able to turn off/on the monitor programmatically.
In fact, I can do that with this piece of code:
HWND hWnd = GetSafeHwnd();
::SendMessage(hWnd, WM_SYSCOMMAND, SC_MONITORPOWER, MONITOR_OFF);
The problem is when the mouse is moving, the display is turning on back.
I tried to use a global mouse hook (implemented in a DLL) which is called and enabled by my main MFC application. The hook works great !
Then, in my application, I have this :
InstallHookMouse(); // Install mouse hook which lock all mouse messages
DisplayOff(); // Turn off the monitor
When I move the mouse while the display is turned off, it turns on back. 
Have I to program a mouse filter driver to lock definitively this mouse and then, the monitor will not turn on back (until my application will decide to turn it on), or is there another solution ? 
Thanks.

If you turn the monitor off programmatically, how is it expected to turn back on other than via the mouse or keyboard?

That's right. I badly expressed myself. 
As the same way I can turn off the display programmatically, I will turn it back on programmatically. I don't want the user can turn on the screen. That's why I tried to lock mouse moves, but it does not work.
Any solution(s) ?

Unless you can convince me otherwise, I consider that to be very non user-friendly. If I'm working on the computer and some application decides that the monitor needs to go off and I can't turn it back on by moving the mouse, I would seriously consider removing that application.

Yes, you're right for this point, but my application is targeting PC which displays multimedia messages on screens (LCD or Plasma) and, normally, there are no interactive users on these machines.
My application must turn off/on screens when no messages are displayed in order to save LCD/Plasma life time. My solution works well because, for that kind of PC, there are no users, but I want to develop my application properly, and I cannot accept that the screen could turn on without my application.
Maybe this is not possible on Windows platform to turn off properly the screen. 
The last thing I would say is that I could do that on Atari ST platform, and fifteen years later, I could not do the same thing on Windows platform fifteen years old  ?!! I think this is the progress...
Thanks for your response.

the SC_MONITORPOWER doesn't really turn the monitor off, it only make use of the power-saving feature of the monitor ( just like the screensaver does )

Yes you are right, but my purpose is to use this power-saving feature from my application. I want to be able to turn on/off monitor when I need, and no turn back on of the display when the mouse is moving.
Maybe are there softwares which can do that ? 
Thanks.
