I have Visual C++ .NET 2003, and wanted to learn how to create basic applications (and games) for the windows mobile 2003 PocketPC operating system. (I actually wanted to learn for Windows Mobile 5.0, but don't have Visual Studio 2005).
Does anyone know where I can find any tutorials for this? I have very basic C++ programming knowledge.
Thanks in advance!!

Well, I suppose I found the answer to my own question! If anyone else is wondering, the proper documentation is right here:

I have some tester and every time after it test,It will output the result in text file and keep it in the directory for example C:\Data.
I want to get the data of these file in real time for process some job.
My question is how I detect that now the file already happen and how to get the file name(if the file name is the barcode of each board).

Are you wanting to monitor a folder for changes to a file? If so, check out ReadDirectoryChangesW() and/or FindFirstChangeNotification().

Can you give some example

Hi people
I'm working with a windows hook, and I intercept WM_CREATE for all the windows.
I need to know if a window is going to be visible, I tried using IsWindowVisible(HWND) and checking WS_VISIBLE flag (wich are the same :S) and I always get false, because the window is not yet created.
Do someone knows how can I do to know if the window beign created is going to be visible?
Thanks in advance

Did you look at the CREATESTRUCT in the LPARAM of the message?

Yeap, im testing it like this
if(pCreateStruct->style & WS_VISIBLE == WS_VISIBLE)
and always is false 
|
|
|
|
|
if((pCreateStruct->style & WS_VISIBLE) == WS_VISIBLE)
led mike
|
|
|
|

If I use
if((pCreateStruct->style & WS_VISIBLE) != WS_VISIBLE)
(notice the != )
it works, another computer science mystery.
Thanks a lot for the tips mate

Well if I follow the entire thread correctly it is not what you want since you are now testing that the WS_VISIBLE style is NOT set!
Consider this possible window creation sequence:
A) application code calls CreateWindow passing a style.... say WS_POPUP
B) OS sends a WM_CREATE containing the style
C) your hook recieves this message and the style WS_VISIBLE is not set
D) application code handles the WM_CREATE message and changes the window style to WS_VISIBLE

Damn, now it works because it shows all

I need to get only the applications that appear in the task administrator.
The filter only shows user apps with a visible window.
Im trying to do the same kind of filtering.
but it seems that WS_VISIBLE is troublesome...
Maybe I can check another style, and get the same results..
I dont know, for example, WS_SYSMENU or WS_CAPTION, the only problem I see is with skinned apps that have a simulated SYSMENU :S
What do you think about this approach?

At this point I am not convinced that I have a complete understanding of the requirements.

I guess you refer to the "Windows Task Manager" and the list of processes in the "Applications" tab?
If so there is a completely different way to accomplish that rather than using a System hook. There are APIs that allow you to get the list of running processes.
I would think some Google would find articles and sample code to get you much of the way there. There might even be a Code Project Article. The MSDN Documentation[^] on Process Enumeration is a good place to start if you want to figure it out for yourself.
One example approach might be using the GetStartupInfo() API that returns a STARTUPINFO structure. The structure has a member for which the documentation states:
lpTitle
For console processes, this is the title displayed in the title bar if a new console
window is created. If NULL, the name of the executable file is used as the window title
instead. This parameter must be NULL for GUI or console processes that do not create a
new console window.

I will check that approach using GetStartupinfo
I have the hook, to know among other things, when a new window is created by a user.
The hook is used for my "single sign on" app, thats why i'm using it.
If that window belongs to an App like the one in task manager "applications" tab
I need to report the opening to a local service.
The problem is for example with the calculator and other apps.
I get
exe: calc.exe
windows title: calcMsgPump
or some crap like that, that's why I want only the visible windows.

What is wrong with that?

I don't understand, when you start the calculator it shows up in the "Task Manager - Applications" tab. So it "is" visible and therefore you want to find it, correct?

Check the win title.
I get as if two windows open
calc.exe Title:Calculator <- This one is OK
calc.exe Title:CalcMsgPumpWnd <- I dont see this one either in Applications tab or my screen
I would like to obtain only the apps I see in Task Manager apps tab.

ok that clears that up.
You might consider using the hook for WM_CREATE as just an event. Meaning that upon the event you use the process enumeration methods and process API's like GetStarupInfo() etc. to build your list.

This syntax with all those brackets is scaring me....
Can someone please tell me what is going on?
for ( unsigned int j = 0; j < ms_numInstances; j++ )<br />
{<br />
( *( (Ball*)(ms_instances[j]) ) ).m_stateTimeInterval = timeInterval;<br />
}
Thank You!

Is casting whatever there is inside ms_instances array to a Ball object pointer, and then is refering to that object that is beign pointed, you can resume it like this:
Ball b;
b.m_stateTimeInterval = timeInterbal;
Obviously dont replace the code, is just for you to see the same in a more simpler way
Hope it helps
