Hmmm. Ok. I'll have a look, because it sounds like a bug to me. The output of the Win32 FindFirstFile() function can definitely be used - I use it all the time.

Thats true. The Win32 function returns information about the first file, but CFileFind::FindFile doesn't 
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

 I just had a close look at the source code. For some reason they buffer the returned data so you're always one file behind what FindNextFile() returns. I always use the Win32 functions. Much easier

O damn, I cannot read the docs 
MSDN on FindNextFile:
<br />
Return<br />
Nonzero if there are more files; zero if this is the last file, and the previous call to either FindFile or FindNextFile returned nonzero. To get extended error information, call the Win32 functionGetLastError. .
So the (in my opinion stupid  ) function returns 0 if it returns information about the last file. I expected it returns 0 if there is no more file.

Aah. So you need to do
BOOL res = ff.FindFile(_T("filespec.whatever"), 0);
while(ff.FindNextFile())
{
}

i guess i'm to late... but heres the code
CFileFind ff;
if(ff.FindFile(sPath+"*.bup"))
{
while(ff.FindNextFile())
{
InsertItem(ff.GetFilePath(),atoi(ff.GetFileTitle()));
}
InsertItem(ff.GetFilePath(),atoi(ff.GetFileTitle()));
}
ff.Close();

I am working with Visual C++ 6.0 in an MFC project and I lost/deleted corrupted my resource.h file. Is there a way to have Visual C++ auto generate my Resource defines. This is my worst nightmare I had probably over 1000 defines. Thanks in Advance
I think im going to be sick  (

Tom,
Thank You. I did check this site and unfortunatly for me "Resource ID organizer" is based on the resource.h. As you already know this file no longer exists within my project. Fortunatly though "Resource ID organizer" is a great IDea and I will probabaly add it to my toolkit. I still have my .rc file and I may be able to extract **_**_** and auto generate IDs, I guess I was sort of hoping that I would not have to do this. Please know that the help you gave me is greatly appreciated.
Thanks again
Cheers
Alex

Oops. I haven't used the product in a very long time and for some reason was thinking it worked from the .rc file. Anyway, I'm definitely glad to hear that at least I was able to point you in the direction of a useful utility. Good luck with the resource.h problem.
Cheers,

Dude, I think you're screwed 
If it was me, I would write a little Python script to scan your RC file and extract any strings that matched the pattern IDC_[A-Z]*, IDI_[A-Z]*, etc., assign them uniqe numbers and print the results out as a list of #define's. This will probably need a bit of tweaking by hand but it will do most of the grunt work for you.
Then I would think about a backup plan...

Here is a function, can you tell me the function of "RUNTIME_CLASS"
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CStudentDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CStudentView));
Thank you in advance!
|
|
|
|

RUNTIME_CLASS is a macro that returns the static CRuntimeClass member data for a given class which allows the function being called (the CSingleDocTemplate c'tor in this case) to validate RTCI (Run-Time Class Information).
To be more specific, the CSingleDocTemplate needs to verify that a CDocument-derived class, a CFrameWnd-derived class and a CView-derived class are all being sent. As a result, this macro is used in passing those values.

Hi, all
When is it necessary to use critical sections in a multithread application? I have read that it should be used when “manipulating shared resources”, but what do those that really mean? Does it mean when manipulating: global variables, allocated memory chunks or files? And does “manipulating” mean: reading (probably not), writing or reallocating? Could anyone please demonstrate some code examples for typical situations when critical sections should be used?
Thanks in Advance

Use it when you assign global varibles, reading is safe.
Allocated memory chunks and files, don't know.

not really, when it's not an atomic operation - anything above size of 4 is in danger: you might catch the first half before the modification, and the other afterwards.

Oh, okay!
I've learned it from CP when I one time also talked about critical sections and threads etc here.

The best advise I saw was if you think you need a critcal section then you probably do, err on the side of caution.
Manipulating, IMHO, means changing a shared resource, if a file is open for reading only by all threads then you don't need it, but if one thread writes to the file, then you probably do. Having a global variable is not a good idea at the best of times, but especially not in a multi threaded application.
I would recomend the book "Multithreading applications in Win32" by Jim Beveridge and Rober Wiener.

Whenever > 1 thread needs read or write access to a resource (memory/disk/database record whatever) you typically need to synchronize the access. Depending on the resource it may be possible for > 1 thread to have simultaneous read access, but there may be a bigger picture issue such as one thread writing to the resource when others are reading it. You then need to go a level higher and see whether transactions are needed etc.
Bottom line is you need to go read a good book or two on multithreaded design and implementation and all that entails. Multithreading is a whole world unto itself where deadlocks occur at the blink of an eye. And debuging multithreaded apps is way harder than single threaded apps.

You should guard all non constant data that you share between threads with some sort of locking mechanism. 'Manipulating' in this context, probably does mean writing. A critical section is a spin lock, it uses an atomic instruction to repeatedly test for and aquire the lock. This makes critical sections unsuitable for locking resources that may take a long time to become free, the other threads will consume cycles waiting for the lock. You should use a kernel lock in these cases, such as a mutex or event. Critical sections are only suitable for syncronising threads, not processes - they rely on shared memory.
Have a look at the boost thread library http://www.boost.org/libs/thread/doc/[^], it makes it a hell of a lot easier to write correct multithreaded programs.
Ryan.

Thanks mates
I am beginning to realize the many disadvantages of using multithreads.
It’s not as “perfect” as I imagined, but then again nothing ever is

There are several options out there such as drag and drop where you can change the order of a list control. So, when the user modifies your list control,
How do you save changes made to a ListCtrl by a user? (so that those changes could be loaded in at a later time)
Any suggestions would be helpful.
I wish I could type better ...

I'm not sure I follow the question. The ListCtrl (SysListView32) itself doesn't do anything magic to save its state or contents. You're responsible for doing that. Having said that, the ways in which you can persist the order of your list control's contents are way too numerous to get into without more specifics on what you're trying to do.

create your own ListControl Class and when the destructor is called, store all the info about the control somewhere. the registry?! I use a .mdb file and some SQL, so I can change the ListCtrl "on the fly"
