B should call WaitForSingleObject on A's process handle which A should pass to B

I'm using some COM components in my VC++ project, I was expecting one of those methods return "_RecordsetPtr", but it in fact returns "IDispatchPtr", I'm new on COM stuff, how to convert it into a _RecordsetPtr? Thanks a lot.

I had a look on Code Project but could not find what I was looking for.
Can anybody direct me to an article that covers adding a button to the title bar of an application. I want to add one next to the 'minimize' button.
Thanks - Joel

would you please tell me about som win32 API which provide
accessing(Read/Write)
to FAT32 logical partion on my hard disk.
As mater of fact,I want to read or write some data from/to FAT32
partitions in
my VC++ program.
I perform it on FAT16 system with using VWIN32 services and
_DIOC_REGISTERS
but it failed on FAT32.
there is some assembly snippet code in MSDN help library,but I
couldn't compile
and run it in VC++ with __asm keyword in my code as see below
__asm{
mov si, 6001h ;write normal file data. SI=0 for read
;see "In Write Mode" below for more write
values
mov cx, -1 ;cx must be -1
mov dx, seg Buffer
mov ds, dx
mov bx, offset Buffer ;See below
mov dl, DriveNum ;See below
mov ax, 7305h ;Ext_ABSDiskReadWrite
int 21h
jc error_handler ;carry set means error
}
I got some compile error on line 3(mov dx,seg Buffer) and on line
5(mov bx,offset Buffer).
I tried it with _DIOC_REGISTERS and DeviceIoControl with VWIN32 file
handler
but i got error number 87 that means "incorrect parameters".
please help me with your advices or introduce me some useful sites to
solving this problem.
please sne it to

if you declare the amount of info that you want to store in a char like...
char ID[10];
that would mean that id has 10 slots + \0; right?
now, if i would want to print out all the info from char ID... wouldnt i just..
cout << ID;?
and if you wrote:
cout << ID[2];
you would get the third memory slot, right?
why cant i set M_ID = ID? M_ID is [10] and so is ID.
bool ID::SetID(char ID[10])
{
M_ID = ID
return true;
}
i get an error when i put this in, and the only way i get rid of it is if i make:
ID[]; and within the [] i would have to have a number. but i want all of ID = M_ID.., what do i do? what do i put in the []?
also... if there is a good tutorial that teaches how to compare data, and all the little detail of do what im trying to do, please make note of it.
Thanks!

A C-style string is stored in a char array, however a char array is not magically a string. You must ensure that the array is properly null-terminated. The way you do that is to always use the string functions when manipulating strings.

No, that declares a 10-character array. Again, it's not magically a string. It just contains 10 characters.
SilverShalkin wrote:

As long as ID is null-terminted, that's correct.
SilverShalkin wrote:
bool ID::SetID(char ID[10])
{
M_ID = ID;
}
That is an error because you can't assign strings (or any arrays) with =. You copy a string with strcpy().

Any C beginners book. And you can look up in MSDN if you have any problems.

hi, all.
since the COM program must include the afx.h(once include afx.h, cannot include windows.h), and the project setting must "use mfc in a share library(or static library)", does that mean the COM must require MFC support?
|
|
|
|

Not at all, COM and MFC have no dependencies on each other, although you certainly can use them together. Are you still having trouble compiling with a reference to IActiveDesktop* ?

Thanks Mike. my problem has been solved since i include the afx.h, afxdisp.h, and wininet.h, i just got a little bit confused about that, so i answer that question.
well, as you said, COM and MFC have no dependencies on each other. but on the other hand, i still cannot complied that program with the project setting "Not using MFC". could u explain that, or give a simple example.;)

IIRC your original code didn't use MFC, right? #include'ing afx*.h is not the right thing to do, since those are MFC headers.  #include wininet.h before shlobj.h and you should be set.
(If your program is using MFC, then just change that combo box to the proper MFC type [shared DLL or static LIB].)

I have a *.chm file already. but how can I display it when menu item Help->Help Topics is clicked?
|

When I input text in a multiline edit box, if I type the text
to the edge, it automatically word wraps to the next line.
If I check HSCROLL, it does not word wrap, but it continues
on horizontally indefinitely. How can I make a multiline edit
box NOT word wrap without activating HSCROLL? That is, when
text gets to the edge of the box, it sticks until the
user hit carriage return forcing it to the next line.
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle (an overworked graduate student)

What you want to do is to disable an edit control's word wrap. I am not sure you can directly do that. But you can use the EM_SETWORDBREAKPROC message to set your own word wrap handler and then do nothing in the handler. It might work, might not work! It's worth a try anyway!

In the resource editor, turn OFF Auto HScroll and make sure Want Return is turned ON.

Sorry, i misread the question; my previous response should have been:
In the resource editor, turn ON both Auto HScroll and Want Return.

Is there any way of removing word-wrap without clicking
Auto HScroll? If I click HScroll, then the user and
type text horizontally forever. I just want them to
go to the edge of the edge box.
Please, any response any one can give me will be greatly
appreciated.

Ouch, why do you want to do that?
I think you could probably implement it by handling the EN_CHANGING notification and just discarding keypresses after they'd reached the end of the line. To make it a bit easier, you'll need to use a fixed-width font and calculate the maximum allowed width ahead of time.
