I installed VC++ 6.0 on Windows 7 Ultimate x64.
Sometimes when I debug the MFC program, I press Shift+F5 to terminate the debug, but the program shows "not responding" and VC++ 6.0 IDE shows normally.
Then I want to kill the progress with Task Manager, but failed. I try to terminate the progress in CMD with administrator permission, still failed. Then, I download ProgressExplore.exe from Microsoft's site, and pskill.exe. I just can't terminate the disgusting progress.
When I log of Windows, the Progress can be killed and when I close VC++ 6.0 IDE, the progress automatically terminated. But as you know, it's miserable to debug programs in this way: debug one time, close the VC++ IDE one time.
Anyone can tell me how to force to kill the specific progress with overwhelming permission(just like Windows did when close or log off)?
Thank you in advance!

It might be better to look at your code and try to determine how your program gets into this state. Do you have a closed loop somewhere, or a process wait that cannot be stopped?

No, I think this is the issue of incompatibility(Win7 X64 and VC6.0).

Fine, now you need to do some testing to confirm it.

did you try
taskkill /f /t /im devenv.exe
to make sure you kill the child process/app?
|
|
|
|

It does't work. I only want to terminate the debugged app, not VC6.0 IDE.
Thank you all the same!

When you are debugging, on process tree debugging app is the child of the MSDEV. could you please check at what exact location it is not responding is it any hardware call or IO call!

When debugging program with VC6.0, the debugged app process attach VC6.0. And the process is the child of MSDEV.exe. But when I press Shift + F5 to stop debugging, VC6.0 CANNOT terminate the app.
ProcessExplorer can't terminate the app, either.
*.exe wWinMainCRTStartup(found by click properties in ProcessExplorer).
I want to terminate the app, not VC6.0!
Thanks for you reply! Any help?

Hi,
Visual Studio 6 is completely unsupported on Vista+ operating systems. There are literally dozens of incompatibilities so I do not know what is causing your IDE to hang. If I had to guess... I would guess that the operating system is waiting on an I/O request to complete. Probably because the VC6 IDE is calling DeviceIOControl after or during the termination/detachment of the debugger resulting in a race condition. In these hangs... TerminateProcess does not succeed because the system is infinitely waiting on an I/O cancellation. The I/O cancellation will never succeed because the process was partially deleted and no longer has any allocated address space (which contained the information required for I/O cancellation!).
Anyway it doesn't relly matter why it is hanging... you should be running VC6 in XP Mode[^] on Vista+ operating systems. If you don't want to run the VC6 IDE in XP mode... don't worry your not alone. I also do not run it in XP mode. Instead I use the IDE for writing code and then I use WinDbg[^] for debugging the code.
If the application you are building will be used on Vista+ operating systems... you should consider upgrading your compiler so you can take advantage of /GS stack cookies[^] , /SAFESEH[^] and integrity levels.
Best Wishes,
-David Delaune

The following piece of code was working fine in VC++6.0 . When UAC was enabled/disabled , for an administrative user the IsUserAdmin was returning true. We are migrating VC++6.0 to VS2010. After this when UAC is enabled IsUserAdmin is returning false and when UAC is disabled IsUserAdmin is returning true. Why is this failing in VS2010 when UAC is enabled and what could be fix for this.
BOOL IsUserAdmin(VOID)
/*++
Routine Description: This routine returns TRUE if the caller's
process is a member of the Administrators local group. Caller is NOT
expected to be impersonating anyone and is expected to be able to
open its own process and process token.
Arguments: None.
Return Value:
TRUE - Caller has Administrators local group.
FALSE - Caller does not have Administrators local group. --
*/
{
BOOL b;
SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
PSID AdministratorsGroup;
b = AllocateAndInitializeSid(
&NtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&AdministratorsGroup);
if(b)
{
if (!CheckTokenMembership( NULL, AdministratorsGroup, &b))
{
b = FALSE;
}
FreeSid(AdministratorsGroup);
}
return(b);
}
Thanks in advance

See the community comments at the MSDN for CheckTokenMembership [^].
There should be no different behaviour when compiled with VC 6 or VS 10 and executed on the same system using the same AdvApi.dll.

I'm not an expert on the subject, but I do have experience with UAC, Vista + and VS2010.
I spent several months reading up on the topic.
On Vista+, your user account can be made or set to administrator, or the group administrator, just like on Windows XP, in which the setting claims you can make any changes to the system you desire, if your are using the Windows Desktop.
But the Windows Desktop runs in 3 modes, mode 1 is a virtual mode, or a clone of the real windows desktop, mode 2, when you elevate, is the real administrators desktop, and mode 3 is the highest level of windows desktop.
When you ran your code, it said of course you are an administrator, but you have to elevate past the clone desktop, by bringing up the elevate permission dialog in order to actually run code that requires administrative permissions in the real desktop. If you don't elevate, your code will not run, and return an error code 740.
When you set UAC in the manifest to a higher level than AsInvoked, when the program starts, it will invoke the elevate dialog, and elevate the program to the next desktop level.
I suspect your code is old school for Windows XP, and just sort of gives you the actual answer, which is true when running as AsInvoked.
Writing for Vista and Windows 7 is a totally different way of thinking, UAC first, everything else second. You have to get permission from the desktop to make changes to the OS, or keep your programs boundaries in an isolated environment.

Then you should start with some research; put the keywords of your proposed solution into Google and start learning about the features you want to use.

Instead of posting only the code, you should post the compiler error as well. And please edit the post to format the code section properly.

Is it just me or not but in my day we didn't ask for help at the first hurdle and things were hard then, no internet, remember compiling 16 bit code for the large memory model? We had to find the answers ourselves.
It strikes me it is too easy today to throw an ill-formed/undefined question at CP and expect an answer! What happened to research? What happened to thinking out a problem till you got the the very nub of the issue; because once you know the right question to ask, the answer almost suggests itself.
I mean, linked lists, writing data to a file? Thats really simple stuff that anyone studying a programming course should e able to work out for themselves!
==============================
Nothing to say.

Well, you're right in that it's too easy to just shoot a question into the great Internet Void (tm) and sit back and wait for an answer. One of the things that kill me is the number of questions that claim to be "urgent" yet they're willing to wait for who known how many hours for somebody to notice their question on CP or anywhere else. If it's "urgent" you should be researching it yourself.
Personally, I blame the instructors (since apparently many of these questioners are in classes somewhere). Linked Lists, Reading / Writing Files, this is all Computer Science 1 stuff yet there are no apparent "cookbook answers" or "class tutorials" on this stuff that explains it more fully. You'd think that problems with this stuff would be a predictable outcome so instructors should prepare to instruct on the topic.
And maybe it's the proliferation of "online universities" where there is no physical contact with a "teaching staff" who can provide personalized instruction / answers. Back in the 60's, we had professors who lectured and Teaching Assistants who held other classes and a group of top students (Program Advisors) that sat at desks in the Comp Sci Department and helped fellow students through the homework assignments. I did that job for a couple of semesters. Who provides that service now? Code Project and other such sites.
