Create some dialogs of property = "Child", and use

SetWindowPos(...)

to paste them onto your main dialog.

If you still don't understand, mail me and I will send you my sample code.

Yes, this is how I have done it. Also set the Control property of the child dialogs.

there are several classes on this site that do something similar. my own is here. it's a dialog with sub-dialogs controlled by a tree.

Security hole or feature? (IIS related)

I have a COM object which runs on IIS server. From within, I can't access files on another computers in Local network. But I needed to. So I thought about a workaround and created a thread with specified Scurity Attributes. That worked. Now (dunno why) I tried to create a usuall thread (using AfxBeginThread(&Test, NULL)) and ..... inside this thread I could access files on other computers also!

Now here comes a question. Why it is so? And is this a security hole, or a feature that I can use in my programs?

How I understand you simply delegate security attributes from your workaround thread.
If windows security give you access to files on nearby computers then IIS thread also can do that.

Solution:
try to run IIS extensions by special user, which have special security settings in domain, then IIS will only have access to folders and computers were special security for such user is set.

Good Luck

Well, I think so too. But look, the main thread of COM object is also one of the threads of IIS (inetinfo.exe), but there I can't access files over network. And user settings for IIS are usual, IUSR_ComputerName, which has rights like Guest account (e.g. - no rights Smile | :)

). But a simple thread, opened from this COM object, looks like it has much more permissions... Dunno why. All I want to know right now, if I can use this feature, or maybe it will be fixed as security hole, lol

Visual Studio and Norton Anti-Virus

I have been having problems with visual studio being unable to save files correctly (keeps coming up with 'Another application is using the file') and have found the problem seems to be due to having Norton Utilities installed.

I have tried disabling NAVs auto protect, but nothing short of uninstalling Norton Utilities seems to help.

Has anyone got any ideas how to resolve this?

(I'm running Windows 2000, VS6 and Norton Systemworks 2002, on my WinXP system this seems to be less of a problem, but still occurs occasionally).

Thanks...

I have had compatibility problems between VS .NET and Zone Alarm firewall on an XP professional. And while I was searching the web for similar issues, I found that a lot of people have trouble with VS .NET and Norton Anti-Virus. I guess in your case it's VS 6 rather than VS .NET, but still the incopatibility might exist.

Unfortunatly, on some occasions visual studio loses files when doing classwizard operations... (you have to dig into the temp directory to recover them)

and I get rather ...annoyed... when every time I hit build I get a requester saying 'unable to save file'...

(And our system admin is a little reluctant to allow us to run without a virus checker installed...)

Thanks for replying tho...

I can't run Norton Or McAfee on my Visual Studio 6 PC. Norton keeps me from saving files all the time and blows up MSDev often. McAfee makes compiled so slow I can't stand it.

However, disabling the auto-protect works for me.

You might try to exclude your development directories from checking completely. That should (and back in NT4 and VC4.2/VC5 did for me) reduce the McAffe overhead to not noticable.

Copy the code, generated for edit events in a dialog by classWizard, to your project. Note, that you must specify unique ID for the edit for correct message handling.

mutex owned by a process

Hi,

In my application, I have a given process (I get its identifier as a DWORD, a pseudo HANDLE and its name) and a given mutex name and I have to know if this given mutex belongs to the given process.
Does anybody know how to proceed ?

Thanks,
Robin.

Can you describe situation with more details? Confused | :confused:

For what purpose you want to check is mutex belong to given process?

Maybe you can create a table of pair mutex-PID in shared memory and when needed check is mutex belong to Process. (??? MapViewOfFile function can help with memory sharing ???)
