Hi,
I have a csplitterWnd based class with 2 view and one view contains cscrollview along with some other controls. My problem is when i set the scroll sizes of the scrollview i sometimes get an unnecessary vertical scroll bar. This scrollbar disappears as soon as i move the split. Remember the splitter view is not direct child of the csplitterwnd class. But i still tried to call the recalclayout of the csplitterwnd when ever i change the scrollsizes of the cscrollview. But the scrollbar is still there. Any suggestions please!

Take a look into ResizeToFit or try to SetScrollSizes with a lower value.

how to create a window which will reside inside MDI frame other than views..
for example: can i create a dialog inside MDI Frame window , which will reside in it.PLz help
|

|

a modeless dialog will do that. Look for CDialog::Create()

Thanks for replyin..
i have tried it ... but when i move my MDI frame it doesn't move along with it..
it gets out of MDI frame area...
i want it inside the frame..

A dialog box will have a different frame. Better create new Window being child of the active one.
Diference between Modal and NonModal is if you are allowed to make another things while the dialog is active, but has nothing to do with your question.

Hello,
Is there a decent way to check if the user currently logged in is the Administrator??
Thanks
Draco

do you mean something like this:
LONG WINAPI IsUserAdmin(void)
{
BOOL b;
SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
PSID AdministratorsGroup;
b = AllocateAndInitializeSid(
&NtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&AdministratorsGroup);
if(b) {
if (!CheckTokenMembership( NULL, AdministratorsGroup, &b)) {
b = FALSE;
}
FreeSid(AdministratorsGroup);
}
return(b);
}

 LOL, it is not that difficult, you just need to spend a lot of time reading and experimenting.

The best thing about windows security -- is that you don't have to understand it. All those functions that want a SECURITY_ATTRIBUTES pointer happily accept a NULL pointer!

and still it works, using NULL indicates that default attributes for the process will be used hence the job is done for you. if you need a different attributes then you can set them up, used to be pretty dull and long code but it is getting better. get hold of books 'Writing Secure Code' and 'Writing Secure Code for Windows Vista', that's good start.

Use IsUserAnAdmin.

char szName[64];
GetUserName(szName, sizeof(szName));
strcmp(szName, "Administrator"); I'm not sure how useful this is going to be, however. I would think you'd want to know if the currently logged on user was a member of the Administrator group or not.

Hi everybody,
I'm looking for a kind of MFC class that provides text sliding effects. I mean, I need to have an Edit box where the text inside it goas from the right to the left continiously.
Does anyone know where can I find this kind of class?
Thanks a lot!

iam not sure about any class which can do this, but using some CString manipulations,thread concept and sleep, this can very well be acheived.
if you want this logic, then i can share it with you.

Hello,
I am working on some financial data .I am picking up data from the dump file in a byte type variable . I have encountered a statement that is confusing me a lot a simple example or statement might be helpful :
"empsalary are two-byte integers, high order first, and negatives are
signed magnitude. Users may have to swap the bytes and/or convert negatives
to the complement they use. This can be done by putting the low order byte
first, then turning off bit 15 (the high order bit), then multiplying by -1.
For positive numbers, only the bytes are switched."
what does the above statement really means??

You are about to learn about endian issues. You can read all about it on the wikipedia[^]
This is an long standing issue -- and is based on the processor on your computer. For all of us Windows, we operate as "little endian" -- whereas mac and java folks operate in "big endian" format.
Endianness is just how the processor stores numbers in byte format. There's some handy functions used for socket programming (but also available generally) -- see ntohs()[^]

Endianness is just how the processor stores numbers...
So if the processor ultimately determines how the numbers are stored, what difference does the OS or the programming language make?

it was just a generalization -- about how windows runs on intel, and intel is little endian

IMHO the above statement is clear:
values are stored inside the file as two bytes integers, with most significative byte first, for instance 1000 (that is 03E8h in hexadecimal notation) is stored as follows:
first byte = 3 (03h); second byte = 232 (E8h)
that is:
3 * 256 + 232 = 768 + 232 = 1000</code>.
On the other hand, negative numbers are stored using Sign and magnitude representation (see [^]), hence -1000 will become 83E8h in hexadecimal notation ( 8h=1000binary, i.e. sign bit ON).
Whenever you need to retrieve values you have to always check the sign bit. I give a C code snippet (error checking is left as an exercise to the reader... ):
unsigned char a,b;
int value;
fread(&a, sizeof(a), 1, fd);
fread(&b, sizeof(b), 1, fd);
value = ((a & 0x7F) << 8 ) | b;
if ( a & 0x80)
{
value = -value;
}
Hope that helps
