A variable may have a different value in the release and in the debug build, causing the differing behaviour

Well , to add to it I say you most probably have a code optimization problem in the section of code which looks suspecious to you . You may find the values of variables in release by classical AfxMessageBox(value) displays . I have come across a situation where in release mode a string = "systarg" was represented in stack as "g|a|sys|t" which resulted in change of code flow . I did the following to solve it
Try this
add the following pramas around the section of code which looks problamatic
#ifndef _DEBUG
#pragma optimize("", off)
#endif

..... your code which works fine in debug

#ifndef _DEBUG
#pragma optimize("", on) // désactivation de toutes les optimisations
#endif

Need help with Keyboard device drivers

Ok, first of all hello folks, I'm new here and I'm in a new challenge now that I hope someone will be able to help me.

I'm working on making a Keyboard Device Driver, but I'm completely new at this issue, but not so new about C language.

My goal is to make a device driver to automate an application. In this application I have to press 2 on the keyboard every, lets say, 3 seconds.

Why do a device driver for it? Because SendKeys stuff did not worked, and I liked the challenge.

But it's becoming more then a challenge since I could not find information about Keyboard Device Drivers, the best info so far came from Toby Opferman's Driver Development Part 1: Introduction to Drivers (http://www.codeproject.com/system/driverdev.asp).

So, does anyone have a link, or some piece of code that may help me?

Any info will be appreciated.

Problem with serializing Propeties of an ActiveX Control [modified]

Hi there,

I am a very beginner so please be pacient Wink | ;)

.

I've tried to add an own Property to the Property Page of my ActiveX Control in VC++ 6.0. But I've got a Problem there with serializing it.

I added the Bold line in my Control's Ctrl Class.

void CButtonCtrl::DoPropExchange(CPropExchange* pPX)<br />
{<br />
	ExchangeVersion(pPX, MAKELONG(_wVerMinor, _wVerMajor));<br />
	COleControl::DoPropExchange(pPX);<br />
<br />
	// ZU ERLEDIGEN: PX_ Funktionen für jede dauerhafte benutzerdefinierte Eigenschaft aufrufen.<br />
<br />
	<br />
	PX_Long( pPX, _T("DBID"), m_CTRL_DBID );	<br />
<br />
}

And the Class Wizard added the following bold lines in the PropPage Class:

void CButtonPropPage::DoDataExchange(CDataExchange* pDX)<br />
{<br />
	//{{AFX_DATA_MAP(CButtonPropPage)<br />
	DDP_Text(pDX, IDC_CAPTION_EDIT, m_PPG_Caption, _T("Caption") );<br />
	DDX_Text(pDX, IDC_CAPTION_EDIT, m_PPG_Caption);<br />
	DDP_Text(pDX, IDC_DBID_EDIT, m_PPG_DBID, _T("DBID") );<br />
	DDX_Text(pDX, IDC_DBID_EDIT, m_PPG_DBID);	<br />
<br />
        //}}AFX_DATA_MAP<br />
	DDP_PostProcessing(pDX);<br />
}

But every time I open the Property Page in the Test Container for ActiveX Controls, change the value of my Property, click on "Apply" and "OK" and open the Properties Page again, the Value I put in isn't there anymore.

Can you tell me, what I've done wrong or what I maybe forgot?
Do I have to do something in the Get/Set Methods?

Greetings TheInfernalCrow

PlaySound() in Vista [modified]

I'm having difficulty playing .wav files in Vista. I'm currently using PlaySound(), which works in XP, but Vista does not. I've seen at least one other person with this problem elsewhere, but I can't seem to find a solution. I'm running VS C++ 2005. Thanks.

-- modified at 2:20 Wednesday 16th May, 2007
Perhaps a little clarification. When executing the PlaySound() function in XP (as part of a larger program) the sound gets played correctly. However, when this program is run in Vista, the sound does not get played.

I just used Vista to test an app that has an about box with sound effect via PlaySound(). It worked fine. Have you tried to play the wav file in WMP on Vista? Do you hear any sounds at all?

Best wishes,
Hans

I've tried playing the sound in WMP and it worked properly. I'm getting the path from the registry and the path seems correct. PlaySound() actually returns 0 (error) when I try to don't pass in SND_ASYNC, but returns 1 (the sound was put into the sound queue) when SND_ASYNC is passed in. In each case, the sound does not play properly.

How to block joystick devices

Michael Sadlon15-May-07 10:09

15-May-07 10:09

I am interested in blocking Joystick devices in some game client software I am extending. The software doesn't have any use for joysticks, so disabling them entirely would be even better.

To be specific, I want to block dangerous "joysticks" like Nostromo[^] and Logitech G15[^] which can do macros, simple programs, etc. These are really deadly since players can use them to cheat and create home-made bots.

Belkin's FAQ page says that Nostromo installs as a standard Joystick device if you don't install their software. Anyone know how I can block these devices in my game client only? Perhaps there is a way to "block" joystick input and allow normal keyboard input. If that's not possible, can I disable them system-wide while the game is running?

Thanks for any answers.

I've created a menu and want to launch other projects from the menu project.

Assume I want to launch MyApp.exe from the menu project.

I'm having trouble figuring out the code statement to accomplish this.

Can you help me out with the code?

Thanking you in advance for your help and time.

Check out ShellExecute() and CreateProcess().

Anything I will say you will bring it down to whatever you want.

Do you mean the code to launch the app, or the code to handle the menu click?

You can use ShellExecute() or the older & simpler WinExec().

hello
There are two things here.

WinExec : with this you can launch another process (Myapp.exe) . But you have no programatic control over the exe after you launch it .

CreateProcess : with this you can have the process handle of Myapp.exe so that later you can kill it .
Sample is here
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

if( !CreateProcess( NULL, // No module name (use command line).
"myapp.exe" // Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
0, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi) ) // Pointer to PROCESS_INFORMATION structure.
{
AfxMessageBox("can not start process");
}

Of course if you see MSDN it says:
This function is provided only for compatibility with 16-bit Windows. Applications should use the CreateProcess function.
Now whats your problem?
