displaying sequence of images in a dialog box

27-Oct-04 6:08

To my knowledge, there's not. Like all dialog boxes, a message box belongs to the window class #32770.

Hi guys
Is there a simple way to play a sound that you previously included as a resource?. For only 17Kb it's annoying to have to add a extern wav file to the program.
Best Regards.
Doc

Are you asking or telling? If the former, see if this article is of any help.

Sorry David Poke tongue | ;-P

I've corrected my question.

I'm taking a look your article. I think is what I need to have the resource on memory.
But, what about to play a sound? Wink | ;)

Thanks

In Resource View Right Click On Your Resource Folder
Select "Import"
In The File Types Filter Select All Files Or *.wav If there is
Then Add The File U Want Thats it
Use ::PlaySound(MAKEINTRESOURCE(ID_MYWAVE,m_hwnd,SND_RESORCE|SND_ASYNC/*other parameters if u want to*/);
include the mmsystem.h header file and add the library winmm.lib in the debug and release configurations

I Have A Problem With PlaySound
The Problem I am Having Is when I exit my app the thread created for playsound with the SND_ASYNC returns a value of -1 i know that using ::PlaySound(NULL,0,0) the thread should be terminated safley i tried it but it fails i created a click sound for each mouse click on LButtonDown I use PlaySound with correct params on LButtonUp i use PlaySound(NULL,0,0) but the thread exits with -1 normal terminal should exit with 0

Not a problem. I don't criticize people's speech, either written or verbal, but I will ask for clarification if it is necessary.

Event Log automation

I am trying to pull specific information from the Security Event Log in windows 2000, in Visual C++ 6 for a auditing system I am creating. Using information from MSDN I have been able to extract the event number, the time it occurred, and the user who triggered the event. The last thing i need is the file that was modified. I know this only applies to certain events. How can i get the file that was accessed/modified/deleted? I have not been able to find a clear example. I've tried using GetEventLogInformation but i was unable to get it to work. I also tried get the message map but I failed at that as well. Are either of these the correct approach? Anyone know of any examples? Any suggestions would be appricated.

What file? The event file itself, or a file that an event message refers to?

I configured auditing on a folder on my local hard drive. I want to know what file in that folder was accessed. I see it in Computer Management, when I double click certain events. I want to know how to get that file name from within a C++ application.

Would ReadDirectoryChangesW() or FindFirstChangeNotification() be of any help?

Sorry but no, these functions do not help. I think i need to explain myself better. On my PC i set up auditing on a select folder, "C:\Image_Db". Any time someone looks at one of these files, deletes a file, changes a file, I want to know who did it, at what time, what file, and what they did to the file. The solution i found was to audit these files through windows event logs. Currently i have to manually find the 564 event and then find the corresponding 560 that gives the file name.
I recently discovered a set of API functions that allow for access to the event logs. I am able to get the eventID, the user, the time, but i can not figure out a way to get the file that was accessed. I think the filename is embedded in the EVENTLOGRECORD structure, after StringOffSet, as described in the MSDN website. I want to know how i can get that data out of the structure. I am not sure if this is possible and I have seen no reference to it on the internet. If you can point me in any direction what so ever i would be grateful.

If you know of a better way that i can log all changes made to a file i would like to hear it.

Thank you for all your help thus far.

While ReadDirectoryChangesW() or FindFirstChangeNotification() will tell you the file and the operation on it, the other criteria would need something like a file system driver that creates and attaches filter device objects to target file system device objects to see all IRPs and FastIO requests directed at those drives.

When looking at the event, where does the filename show up (e.g., in the Description box)? As you've found, the message itself is not written to the event log, only the event's id. You'll need to use EventID and SourceName to locate the event in the message DLL.

Custom build

Hello,

I have a Lib which has some objects which are compiled depending on whether certain macros are defined or not. I was wondering if it is possible to have multiple builds of the Lib for the different scenarios and have Visual C++ automatically choose between the correct version of the Lib to use?

Example:

In the Lib:
#ifdef _MACROA
class A
{
	.
	:
	.
};
#endif	// defined(_MACROA)

This means that we have two possible versions of the Lib: one for when _MACROA is defined and another for when it's not.

So the question is how to configure the project settings in the (implementation) App - if such a thing is possible at all - to make it choose the correct version of the Lib depending on whether the macro is defined or not.

Perhaps I should adopt a different strategy?
All insights on the question in hand will be greatly appreciated.

David

You could use a method such as:

#ifdef _DEBUG
 #pragma comment(lib,"SomeLibrary_D.lib")  <font color=green>// Use debug build of library</font>
#else
 #pragma comment(lib,"SomeLibrary.lib")    <font color=green>// Use release build of library</font>
#endif

Depending on which build of your program you will be using, these #pragma definitions will use the corresponding build of the dependent dll.

You could also always add a new 'configuration'.
The 2 defaults are Win32 Release and Win32 Debug, but you can add others, which allows you to define specific project settings for each one. You can create different output files, use different preprocessor macros, include different libraries, etc.

You you could have

Win32 Release With MacroA
Win32 Release No MacroA
Win32 Debug With MAcroA
Win32 Debug No MAcroA

for example.

On the VC 6.0 'Build' menu there is an item labeled 'Configurations...' that invokes a dialog that allows you to add/remove configurations.

Then, when you want to work on a specific configuration, you use the Build|Set Active Configuraiton... menu item to specifically define the one you are working on.

You can use Build|Batch Build... menu item to make all of them at once.
