Hello,
I'm curious about what date type is a HANDLE? Is it an int pointer? Thanks.
|

Not exactly a pointer,it just a handle,you can take some operation on it or with it
I am seeking...
For what?
Why did you ask me for what? I don't know!

Hello ,
As I know from Inside Win2k, when a process creates or opens an object(object is almost everything in Windows ) by name, it receives a handle that represents its access to the object. This is
like a secure pointer taken from OS.
**Object is symbolic link, process, thread, job, section, event, semaphore and ...

I spoke wrong. I mean literally what is it in terms of size. For example, DWORD is really a 32-bit unsigned integer. I'm trying to read some data that contains HANDLE type in a structure. I'm reading it over in a UNIX app. I have no use for the HANDLE, but my sizing will be wrong if I ignore it.

me think a HANDLE is the same size as a pointer; so 32 bits.
look into winnt.h

How about sizeof(HANDLE) ?
|
|
|

I think this will give you clear answer !
typedef void *PVOID;
....
#ifdef STRICT
typedef void *HANDLE;
#define DECLARE_HANDLE(name) struct name##__ { int unused; }; typedef struct name##__ *name
#else
typedef PVOID HANDLE;
#define DECLARE_HANDLE(name) typedef HANDLE name
#endif
typedef HANDLE *PHANDLE;
** This is taken from WinNT.h

HANDLE is unsigned long (DWORD). It is like a pointer because it is unique, but it is hashed to some pointed in memory. Windows manages the memory and this can be shifted and moved around to prevent memory fragmentation, but the HANDLE remains the same.

You could use Xerces, XML4C or a class from here.

At First Objects[^] you can get a fine little XML parser for free. Only the extended version consts money.

I have an application in C++ (VC6.0 SP5 Win 2K) which runs fine in Debug and crashes in Release.
In the output debug window, when running the app in the IDE, I get the following message "Invalid Cache depth".
Anybody has a clue?
Thanks to whoever has!

I don't know about the error, but you might want to take a look at XCrashReport - Exception Handling and Crash Reporting by Hans Dietrich. It covers debugging release mode applications.

I did read his serie of articles.
Unfortunately the bug seems to appear in the MFC dll, so nothing I can do there to trace some code. And the stack does not include any of my functions.
There is also a very good article called Surving the release version, but I still have not found anything useful there either.
Thanks!

Found it!
I was simply using the index -1 in a std::vector... not a very good way to make your program work (and it does screw up your stack  )!
I wish the STL had some ASSERTs like there are in MFC though!

Hi!
I need some help. I need to include milliseconds into my timestamp and I don't know how to do.
For Example:
12:10:47:123
If you even know how to get microseconds, that is also welcome
Thankful for your help,

Look at QueryPerformanceCounter() for high-precision timings.

Assuming that you need clock time rather than duration:
The SYSTEMTIME structure has a wMilliseconds member.
If you need even more resolution you could consider using GetSystemTimeAsFileTime which returns a FILETIME structure. This has a resolution of 0.1 microseconds.
If you need a duration - time elapsed between two points - follow Taka's suggestion.
|
|
|
|
|
According to the documentation, GetSystemTimeAsFileTime converts SYSTEMTIME in FILETIME format, i.e. the higher resolution is not real.

In Visual Studio 6, is it possible to remove a file from a project using a macro (DSM)?
Project.AddFile doesn't seem to have an inverse, which is odd, and annoying.
|
|
|
|
|
Simply highlight (select) it's name on the File View panel and press Del. Watch out, it does not even ask for confirmation!
|
|
|
|
|
I thought of that, but I can't figure out how to select it in the file view. I tried recording it as a macro but all it gives me is 'ExecuteCommand "Delete"' which isn't guaranteed to work.
Is there a way to interact more with the framework?
