I try to record and playback application session with help of WH_JOURNALRECORD and WH_JOURNALPLAYBACK hooks but can’t properly playback MOUSEWHEEL event ( rotation direction is ignored)
JournalRecordProc and JournalPlaybackProc hook procedures use LPARAM ( pointer to the EVENTMSG structure ) to get/pass message specific information during recording/playing.
This EVENTMSG structure has no member for WPARAM information, but key indicator and wheel rotation information are stored in WPARAM of WM_MOUSEWHEEL message. The same problem is with all messages with specific WPARAM info.
How I can correctly play WM_MOUSEWHEEL message?
Thanks in advance

Thanks for reply
But I mean to playback with JournalPlaybackProc :
Syntax
LRESULT CALLBACK JournalPlaybackProc( int code,
WPARAM wParam,
LPARAM lParam
);
Parameters
code
[in] Specifies a code the hook procedure uses to determine how to process the message. If code is less than zero, the hook procedure must pass the message to the CallNextHookEx ..........
wParam
This parameter is not used !!!!!!!!!!!!!!!!!!!.
lParam
[in] Pointer to an EVENTMSG structure that represents a message being processed by the hook procedure.
-----------------------------------------------------------------------
The source of data to fill EVENTMSG structure is WM_MOUSEWHEEL message what returns
WPARAM wParam
LPARAM lParam;
Parameters
wParam
The high-order word indicates the distance the wheel is rotated, expressed in multiples or divisions of WHEEL_DELTA, which is 120. A positive value indicates that the wheel was rotated forward, away from the user; a negative value indicates that the wheel was rotated backward, toward the user.
The low-order word indicates whether various virtual keys are down. This parameter can be one or more of the following values.
MK_CONTROL
The CTRL key is down.
MK_LBUTTON
The left mouse button is down.
MK_MBUTTON
The middle mouse button is down.
MK_RBUTTON
The right mouse button is down.
MK_SHIFT
The SHIFT key is down.
MK_XBUTTON1
Windows 2000/XP: The first X button is down.
MK_XBUTTON2
Windows 2000/XP: The second X button is down.
lParam
The low-order word specifies the x-coordinate of the pointer, relative to the upper-left corner of the screen.
The high-order word specifies the y-coordinate of the pointer, relative to the upper-left corner of the screen.
----------------------------------------------------------------------------
As it turns out there is no place in EVENTMSG for data stored in WM_MOUSEWHEEL message wParam.
typedef struct
{
UINT message;
UINT paramL; // place for x-coordinate
UINT paramH; // place for y-coordinate
DWORD time;
HWND hwnd;} EVENTMSG, *PEVENTMSG;

I don't know if what you stated above is correct. Under my system I follow this logic:
WPARAM is defined as UINT_PTR which in turn is defined as unsigned int
LPARAM is defined as LONG_PTR which in turn is defined as long
UINT is defined as unsigned int
And also under my system sizeof(long) == sizeof(unsigned int). This means that you have enough space in the EVENTMSG structure being passed in to store everything. I doubt there would be any conversion nessisary.
I think all you would have to do is store your WPARAM and LPARAM in paramL and paramH.
Greba,
My lack of content on my home page should be entertaining.

Interesting idea.
I have tried to put contents of wParam words to high-order words of EVENTMSG ParamL/ParamH .
Regrettably it does not work. System works with X/Y coordinates only .
So problem pending.

Problem is solved. I don't find better way, than to mix WH_JOURNALRECORD hooks with interseption of WM_MOUSEWHEEL and sinchronising this messages on play.

Hello
I want becom the handle of the desktopbackround so that i can set a playet movie behind the icon´s of the desktop.
thank you for help and sorry for my bad english.

I now this and this is the handle for the desktop but if i draw in this window and display it i don´t can see the icons on the desktop. I want that the video plays in the backround so that the user can see all of the icon´s on the desktop normal.

My ATL service crashes when it is being stopped by the system (its startup mode is "automatic"). This happens only if the service is running on Windows XP and is being stopped automatically (not manually).
The source code:
HRESULT CMyServiceModule::PostMessageLoop()
{
RevokeClassObjects();
LogEvent(_T("Service stopped"));
CoUninitialize();
SetServiceStatus(SERVICE_STOPPED); // <--- this line causes the crash
return CAtlServiceModuleT<clegnlicenceservicemodule, ids_servicename="">::PostMessageLoop();
}
The debugger shows that m_hServiceStatus is NULL.
Thank you in advance for any ideas.

I am having a problems printing the output for this program. With C++ when I compile and run the program I am left with an exe file. How do I incorporate code to print out the output? Below is the code. Where do I enter it within the program? Basically I want to be able to print the output.

Hi
What happens if you run this code;
ofstream printer("lpt1:");
printer << "test" << endl;
If that prints something on your printer, you're in business and can simply change all instances of 'cout' to 'printer', with above lines added at beginning of the main function.

Thanks Martin,
I will try your recommendation and see what happens. I did not know you had to change all couts to printer. I am a beginner and have been working with this for awhile. I have had many recommendations and probably due to my inexperience I was not able to figure out what was going on.

From a command prompt, redirect the output of your program to the printer by typing:
program > prn BTW, for future posts, there is no need to post all of your code, only the relevant parts. Asking folks to wade through a bunch of code is a sure-fire recipe for getting little to no help.

hai all,
when i connect a Oracle with vc, after closing the application window i am getting "User Break point at &72ff234" an error in a messagebox , and it automatically opens an assembly program and arrow points to the 72ff234 line.
i am getting this only while closing the application after using the database connection. i tested the program , with out connecting to database, i close the app. windows.. i didnt get the error ...

It sound like you have forgotten to disconnect from the database and clean up the appropriate database handles before exiting your application.

Previously (ie. VC++ 6), the Profiler was only included in the Professional and Enterprise versions. Is the Profiler included in VC++ 2003 Standard or do you have to purchase Visual Studio Pro 2003 (since it's not possible to purchase VC++ 2003 Professional separately) ?

How can i implement one function to get the file size of a file which takes pointer to the file path?Please help..
|
|

Hi
Using Win32, you can use FindFirstFile and inspect the WIN32_FIND_DATA structure returned from that (and call FindClose when you leave).
In .NET, that information is available from the FileInfo class.

Why not use GetFileSize()?

The function should take only the constant pointer to the path of the file..
