a little error...;) for the GetIPAdress
no argument is required for this method...
void GetIPAddress()
{
m_IPAddress = do_Something();
} is correct...
When you use this technic you must be careful for critical sections...

i found some code on MSDN and i need to apply it to my application.
the belowe code is example of IWMEncSource::SetInput on MDSN.
this is preparation for encoding data which is form video capture card and sound card.
so the client who connect to the encoder can see what u a seeing
HRESULT hr;
IWMEncoder* pEncoder;
IWMEncSource* pAudSrc;
IWMEncSource* pVidSrc;
.....
// Specify live stream capture from the installed
// audio and video cards.
hr = pVidSrc->SetInput(L"DEVICE://Default_Video_Device");
hr = pAudSrc->SetInput(L"DEVICE://Default_Audio_Device");
// Initialize the encoder engine.
hr = pSrcGrp->PrepareToEncode(VARIANT_TRUE);
but i would like to take data from file like mpg , avi or asf instead of live.
is it possible just to change input file.
help me!!! plz

Hi world,
When I throw an exception I'll want to use a function (or a MACRO) which give me the line number where the throw was detected... for example:
throw SLD_Exception(error_code, "error message", THE_LINE_NUMBER);
...if this line is the 86th, then THE_LINE_NUMBER must return 86...
Is this possible??? How to do that???
(I don't use MFC... and don't want to use it...)
Thanks in advance!

Try __LINE__ for the source code line. __FILE__ might also be of interest - this is the source filename.
Hope this helps!

I have a dialog box with various buttons and controls on it, as well as a static text box which is used as a placeholder, and in code it creates a propertysheet where the static text box is. I set my desired tab order, with the static text box as #13 in the tab order. But instead of tabbing off the #12 order (a button) and going to the propertysheet's active tab/page, it goes to the #14 control (a listview), then, at the end of the ta order sequence, ends up on the propertysheet. Is there a way I can set the tab order so that the tab order is properly set, so that the propertysheet is #13 in the tab order? Thanks!

Check out CWnd::SetWindowPos() - I think that might do the trick!

I looked up SetWindowPos in MSDN, and tried a few things, but none of them affected the tab order from the dialog controls to the propertysheet, and the propertysheet is last in the tab order.
Here is the code I use to create the propertysheet dynamically, IDC_PPS_MAIN is a dialog resource, m_ppsMain is a CPropertysheet object. This code is ran in a dialog in its OnInitDialog() function:
<br />
m_ppsMain.Create(this, WS_CHILD | WS_VISIBLE, 0);<br />
m_ppsMain.ModifyStyleEx(0, WS_EX_CONTROLPARENT);<br />
m_ppsMain.ModifyStyle(0, WS_TABSTOP);<br />
<br />
CRect rcSheet;<br />
GetDlgItem(IDC_PPS_MAIN)->GetWindowRect(&rcSheet);<br />
ScreenToClient(&rcSheet);<br />
m_ppsMain.SetWindowPos(NULL, rcSheet.left- 7, rcSheet.top - 7, 0, 0,<br />
SWP_NOZORDER | SWP_NOSIZE);<br />
<br />
m_ppsMain.SetActivePage(1);<br />
m_ppsMain.SetActivePage(2);<br />
m_ppsMain.SetActivePage(3);<br />
m_ppsMain.SetActivePage(4);<br />
m_ppsMain.SetActivePage(0);<br />

Make sure that the property sheet/pages have the 'control' style set. This style (DS_CONTROL) tells Windows to include them in the tab order of their parent window.

Anybody know about mirring the display driver? Can we assiciate the mirror driver with virtual deskop. I meant no other driver need to active in virtual desktop. Is it possible?

Just a question about good practice.
Is it reasonable to rely upon the order of destruction of a group of objects within another object? Especially in regard to exception safety and readablity.
Specifically. I'm using CComPtr's to attempt to make some of my DirectShow code as exception safe as possible. I've realized that just releasing the interfaces that occurs in the CComPtr's destructors aren't enough if an exception is thrown, and that the whole filter graph needs to be torn down first.
I'm going to put the tear down operation in an another class, and instantiate it on the stack, but I need the destructor of that object to be called before all of the CComPtr's destructors are called.
I ?think? destructor order is controlled by declaration order, but in general is relying upon that fact good practice?
Any help would be appreciated.

It's specified by the language so it's probably not unreasonable
Not everyone knows that so if your code absolutely relies upon it, a comment to that effect is probably in order.

Yes, it is. More specifically, order of creation (just in case you're using pointers to allocate memory dynamically).

It's smart, but how will you remember that two weeks from now. If the workaround is difficult, use this by all means, but COMMENT IT!

Well, it's written, or at least a big part of it is.
The whole reason I headed down this path was to make sure that the classes were exception safe. I've been looking into the Herb Sutter's material (Exceptional C++), and this way seems to be the only way to make any kind of exception safety guarantee. I never realised how much extra work it was going to be, nor the compromises that would have to be made.
Doing proper exception handling is so hard 
Thanks for the feedback though

hey people
have taken your advice, but it just won't work, keeps coming up with the error in the subject line. any help would be truly appreciated..
here's what the code looks like:
#include "stdlib.h"
int* CreateArrayOfRandomNumbers(int nSize)
{
int* pArray = new int[nSize];
if( NULL == pArray );
return NULL; // memory allocation error
for( int i=0; i);
{
pArray[i] = rand();
}
return pArray;
}

your "if" and "for" statements don't need a semicolon at the end.
in this particular case, it shouldn't cause the error you re getting but you never know try fixing that first.

Seriously, be more specific- you shoulda prolly said "shouldn't have a semicolon". OK, OK, you can have empty for loops, but empty if blocks IMO should never be used.

I presume you've just included a snippit of the whole file there. This error is often caused by mismatched braces further up the file where you have one more open brace than you have close braces.
For example :
void MyFunction1()
{
void MyFunction2()
{
}

Remove the semicolon at the end of this statement:
if( NULL == pArray );
There is a misplaced semicolon in this statement (or you got bite by HTML formatting):
for( int i=0; i);
int *CreateArrayOfRandomNumbers(int nSize)
{
int *pArray = new int[nSize];
if( NULL == pArray )
return NULL;
for (int i = 0; i < nSize; i++)
pArray[i] = rand();
return pArray;
}
