You see, adding the size of all logical drives cannot give us the total size of the physical disk.
True, but in your example, why would you need the total size of the physical disk, since not all of it can be used anyway? For example, if you had an 80GB disk, 30GB for C: and 40GB for D:, that would leave 10GB of unallocated space. Until that 10GB is partitioned and formatted, it's of no use, so why include it in any totals? I'm sure you've got a reason for this, but it's not immediately obvious to me.
I wonder if you need to query the BIOS somehow to find out what it knows about the HD?

Well, I got your idea. However, my need is very simple. In Windows 2000 and XP, I can easily get many of physical disk information such as number of Cylinders, TracksPerCylinder, SectorsPerTrack... But in Windows 98, I could not. That's why I posted my question. I think that such information was kept somewhere in the physical disk and was independent with platform. The problem is only the way to get them (depend on which platforms we do use).
About the total size, I think that in some cases, we also need to know exactly how big our physical disk is. That information may be helpful in many cases. Do you think so?

Sure. For applications that partition/format disks, you might have a "This disk is 80GB in size, but only 70GB of it has been formatted. Would you like to format the remaining 10GB?" prompt. I've not ever done such work, though.

Go back to my major problem. In Win98, can I get such information as total Cylinders, TracksPerCylinder...?
Best regards.

Given the Windows 98 restriction, I know of no way. You might try posing your question to the microsoft.public.vc.language newsgroup.

Dear David,
How can I do that? I mean how i can post my question to that newsgroup?

Well, this seems to be a trivial question, but it's giving me problems, so I've decided to claim for someone's help.
In a Win32/MFC application, some kinds of resource (as images, for example) are stored in independent files, wich can be easily accessed and modified. I pretend to have some of these resources encapsulated and/or secured in such a way that they are not trivially engaged by users. This surely implies to provide some kind of encapsulation in order to have not first-look recognizable files. But I was thinking, too, in adding such resources directly inside the executable file.
I don't know if I've explained this clearly enough, and I know that my English is too far from correctness. But if someone could help me, no matter in what way, I'd be very pleased. Thanks for all.

I want to get a handle of a thread of other process in the Win9x.
but th API OpenThread() only can work in Win2K or later.
The best I've managed to do so far is:
DebugActiveProcess()
while( WaitForDebugEvent(&debug_event, ...))
{
....
ContinueDebugEvent()
}
Which will enumerate every thread in a process, filling a DEBUG_EVENT
structure with each thread's handle.
This works, but it's not the prettiest way to do it.
It also has the very unfortunate side-effect of attaching the process as a
child of this one.
What should I do  ? Please help me , Thanks a lot!

Interesting.
As far as I know, you cannot get a handle to a thread from another process because of security reason. The only way is if you spawn the process via CreateProcess(), etc.

I met a problem in MFC extension dll creation and I write to seek your kind assistance.
I created two project: Main.dsw and server.dsw ;
[1] In Server.dsw, I defined a series of classes, derived from CObject, and implemented them with serrialization support;
[2] In Main.dsw, in the document class, I defined a TypedList like this:
typedef CTypedPtrList<coblist, cobject*=""> CActor;
void CXXXDoc::Serialize(CArchive& ar)
{
Actor.Serialize (ar);
}
I then added some objects in this document, all these objects are instances from Server classes;
The problem is, every time I save the document, and then reopen the saved document, a "Unexpected file format" error pops up.
I debugged into the code, and found that it occurs in CObList.Serialize();
However, if I do not encapsulate the classes into server.dll, instead, I directly use them in Main.dsw (I put the source code in main.dsw ), the serialization is ok. This is so strange. Can anyone give me some hints on this?
I have been working on this for half a month, and searched MSDN for quite a few days, will you pls give me a hand?
Your kind help is highly appreciated.

Hi there.
I'm having a problem with a project i'm currently working on.
I'm writing an MFC extension dll to simplify the reusability of code that i've written. The Project itself is called "STHDll" and i added all necessary
files to it. It currently has the two standard configurations (DEBUG and RELEASE).
In the Project's linker tab i use the following command line:
(Release)
/nologo /subsystem:windows /dll /machine:I386 /out:"../bin/STHLib.dll" /implib:"../lib/STHLib.lib"
(Debug)
/nologo /subsystem:windows /dll /machine:I386 /out:"../bin/STHLibD.dll" /implib:"../lib/STHLibD.lib"
Now if i compile it the linker gives a warning: LNK4070
STHLibD.exp : warning LNK4070: /OUT:STHDll.dll filename directive in .EXP differs from output filename "../Bin/STHLibD.dll"; ignoring directive
Now if i open the .exp file i only find references for "STHDll.dll".
Teh same is for the .lib file.
Can anybody help me with this problem, so that i can create the proper .exp
and .lib files?
Many Thanks.

hi,
After I installed the latest PSDK ,
When I try to compile I get the message '...\rc.exe This program expects a newer version of windows'.
I am running ME.
what could be wrong with the resource compiler?
I am using VC6 SP5 , with latest platform SDK.
regards
Hari

I have this same environment at home and have no troubles compiling (this is in contrast to Michael's comment about Microsoft disabling the product). Perhaps you need to reinstall SP5 with the thought that it might provide the "correct" resource compiler.
What happens if you run the resource compiler from a command prompt? Change to the C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin folder, type rc, and see if it gives you the "...\rc.exe This program expects..." or the RC1107 message.

hi,
NOP, the same message. I copied rc.exe and rcdll.dll from visual stidio 6 to platform sdk/bin. It works ok, but i know it is not right.
Any thoughts ?

MS purposely crippled it so it will not run on 9x/Me.  If you have access to older Platform SDK CDs, go back to around Oct 2001 or so and grab the RC.exe from there.

Hi,
How can I read raws and columns of a .csv file?
I would like to move from one column to the next,, how can I do that ?
Ehsan Behboudi

The raws (rows) of the file can easily be read with CStdioFile::ReadString(). The columns can be handled with AfxExtractSubstring(), or CString::Find(). There's more than one way to skin a cat, however.

how do I use those commands in my code
right now this is how I read my .csv file
ifstream infile(file1);
char temp[500];
infile>>temp;
// so now i want to move to the next row or column, how do I do that with your syntax?
Thanks

Very seldom do I use streams so this might not work, although it should get you close:
istream in;
while (in.eof() == 0)
{
is.getline(temp, sizeof(temp));
}

Define "not working."

Some things that struck me as odd:
float atol;Not sure what you are trying to accomplish here.
int main(int argv, char ** argc)Traditionally, argc is the number of arguments, while argv is the argument vector.
if( XOR(argc[1],(unsigned int)atol(argc[2]) ) )
int XOR(char * filename, unsigned long key)In the call to XOR(), the second argument is being cast to an unsigned int, while the function's prototype is expecting an unsigned long.
