I managed to enumerate currently running the processes, but I couldn't show their starting (or creation) time. How Can I do this?

If you have a handle to the process, you can use the Win32 function GetProcessTimes. However, it only works on NT/2K/XP systems. Smile | :)

in my MDI app.......I inserted a CRecordView-base Class named CLogin
when I input my ID and my Password .... I want this form disappear but when
app run to this line
GetDocument()->OnCloseDocument();
Login Form is hide and a Error MessageBox show
Unhandled exception in QLBH.exe (MFCD42D.DLL): 0xC0000005: Access Violation.
and cursor point to this line in DBCORE.CPP like following:

BOOL CRecordset::IsOpen() const
	// Note: assumes base class CRecordset::Close called
{
	if (m_hstmt == NULL)     // Error in this line //
		return FALSE;
.....
}

I tried use:
SendMessage(WM_CLOSE) or SC_CLOSE
or GetParentFrame()->SendMessage(WM_CLOSE);
but no result
help me
thank

<code>

{
	// TODO: Add your control notification handler code here

what files to distribute with my MFC app?

I am wondering what files to distribute with my MFC app to get it to work on various different machines. In my project settings, it says I am using MFC in a shared DLL. When I go to run my app on my XP (versus my 98 where I developed it), it doesn't work.

So, obviously I need to distribute some files, but which ones?

Thanks.

Use Dependency Walker on your EXE to tell what DLLs it uses. This comes with VC 6 (not sure about 7.x since I don't use them), or you can get the latest version from dependencywalker.com[^]

I used dependency walker. I copied the files: mfc42.dll and msvcrt.dll from my visual C++ CD and put those in my target machine's system folder. I also copied the release version of my app onto the target machine and it still doens't work. The target machine is WinXP and when I run my app it comes up with some dialog box that really doesn't explain the error.

**EDIT**
I looked up in MSDN about this and they said I had to register my DLLs on the target machine. How do I do this?

Any more help is appreciated. Thanks.

1. You do NOT have to register the MFC dll, or the C runtime ( which is what MSVCRT is ), only COM dlls need to be registered. As an aside, if I were you, I'd look at why you need the C runtime, because where you are using C, you may find that C++ provides a better alternative anyhow.

2. In either case, the DLL needs to be in the same directory as your exe or a directory in the search paths, like system32. I find it hard to believe that WinXP does not come with the MFC dll though.

3. Finally, if you really want people to help you, have you considered telling us what the error message is ? Just because you don't understand it, doesn't mean it isn't actually useful.

OK I figured it out, thanks for all the help guys. The problem was part of my code, namely GetProfileBinary. I fixed it, so it's all good.

I finally understand all this stuff. Thanks.

Why do you always do that?
Trying to "correct" people. I use C all the time, for a lot of things I like the good old CRT functions way better than the C++ counterparts.
I often prefer C with Classes Wink | ;)

And one thing that really sucks, is seeing the "I know better types" saying such crap all the times.
There have been other people saying the same, so I'm not the only one Wink | ;)

Because if someone asks a question, I presume they want an answer ?

Anders Molin wrote:

A lot of old timers or people who learned C first because of the inadequacy of universities tend to cling to C. And sometimes C provides a better alternative. I have written whole apps in C, and some of my C++ code relies on the CRT. But, for example, C style file handling and string handling are both ugly as hell, and most people who use them have no idea that they are using C and that C++ provides a better alternative. Many people I work with have been thankful that I took the time to pull their programming into the 1990's by showing them these things.

You'll note that I said 'you MAY find that C++ provides a better alternative'. If you can't tell that this means I am making a suggestion and not saying that all dependancy on MSCVRT needs to be obliterated, that's your problem.

You and all the others can go to hell, collectively. If I *don't* know better than the person asking the question, why the hell would they ask, or why would I try to answer ? I've made a suggestion, for free. If the original poster does not like it, that is fine. If you, as a third party feel the need to throw your 2 cents worth in, one just has to wonder why. If the C++ community as a whole didn't tend towards ignorance of the difference between C and C++, and the existence of the STL, then I wouldn't have to presume that a lot of people who use antiquated methods do so because they don't know better. I try to avoid just posting 'use the STL' without making suggestions on whatever method the person *is* using, but if the STL would tend on average to provide a better alternative, then an answer that does not say so is incomplete. Excuse me for trying to help.

Let's see, shall we ?

I suggested that if there is a dependency to MSVCRT, it's *possible* that he could be using some old C functionality that C++ does better.

You wrote:

I again clarified that I didn't claim that the C library was useless, but that a lot of people don't even know the C++ stuff is there, so I suggested it was worth a look.

Anders Molin wrote:

Then don't make an ass of yourself. I maintain that if people ask questions, they are looking for answers, and that my answer was both correct, and not what you claimed it to be. Using really small words, it goes like this. C++ has stuff that is better than C, and a good coder knows about both so he can make the right choice. Too many don't know and so make the wrong choice, because universities don't *teach* C++, they teach C with classes.

Of course, but why do you bring it up every time you answer a post where people mention crt?
Thats what keeps bugging me, i know you give some great answers, but why also try to "convert" people to use C++ just because they mentioned a crt function.

I guess I am just accustomed to people using the CRT because they don't know there are alternatives. I probably have STL blinkers on, I'll admit that. But the majority of times I get to discuss it with people, I do find that they really don't realise it's not the only alternative.

I have to say that I dont like STL much, that probably make me a bit quick too.
I have made a lot of server applications that did big amounts of string handling. I tried to convert some of the code from TCHAR* tp std::string, but the performance was too bad.

Ok, STL is good for many things, but not everything Wink | ;)
