How do u combine two projects into one single project.
Example,
Programmer 1 : Programmed one dialog box for part of the whole project.
Programmer 2 : Programmed another dialog box for another part of the whole project
Now another programmer needs to combine these two projects into one. Both of them used MFC and classwizards. How does he combine the dialog boxes and everything???
Hope someone has a solution.
Thanxs.
P.S. Newbie qn....

Hi !
I've done an little client/server application which works on Windows CE.
When I launch the server on my desktop machine, I can connect a client from Pocket via ActiveSync. But at connection, the client IP address shown by the server is my desktop machine IP address. Then, when I launch the server on PocketPC, I don't have any address to connect to ! Is ActiveSync giving an IP address ? If so, how may I take it ?
Thanks for any help.

I am trying to use a CTreeCtrl in a CDialog box.
I want to set the background colour of the tree control to the same colour as the dialog. I have tried using setBKColor(COLORREF clr), however this didn't work, I also tried getting the CDC from the CTreeCtrl and seting the color that way and it still didn't work.
Any ideas on why?
do I need so set some special property to enable me to change the background?
cheers

CTreeCtrl::SetBkColor works perfectly for me. The method is implemented with TVM_SETBKCOLOR, which is available on Win98, Win2000 or on systems with IE4 or later installed. Maybe you're using some ancient Windows version?

Yep it appears you are right.
What i was trying to do was get the colour of the dialog that the tree control was on, and set the background of the tree control to that colour. It appears that the setting of the tree control background was working fine, but getting the colour from the dialog was not working, it was always returning white, when I want the dodgy windows grey colour!
any ideas how to get the real background colour of the dialog.
cheers

You want this:?
const int d = 100;
int var[d];
for (int i = 0; i < d; ++i)
var[i] = 0;
cout << var[5];

Not really, even though that is the most logical way to do it. I am curious to know whether in C it is possible to substitute a piece of a variable name with something like a string. e.g:
int variable = 7;
char c[] = "able";
cout << vari%c;//no problem here b/c I'm using a placeholder or such.

No, compiled languages like C and C++ do not retain 'variable names' in generated code. Constructs like yours are generally used in scripts.

Your looking for enum() kind of functionality, as found in high level languages such as Perl and SQL. Obviously this isn't possible with a compiled language, because you'd have to ship the compiler with the application!!!

Hi,
How can get the free space available in a drive?
Thanks
Neha

GetDiskFreeSpace() ought to do the trick.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

BOOL GetDiskFreeSpaceEx(a,b,c,d);
a = "c:\directory" or NULL. If NULL, function returns space in drive where function resides.
b = pointer to variable to receive free bytes available to user of the calling thread.
c = ditto for available (free+used) bytes.
d = pointer to variable to receive total bytes on disk.

I found a smaple code from MS. And here is the link:

I do some works on WM_PAINT:
//////////////////////////////////////////////////////////////////////////
CDC* pDC = GetDC();
CDC cacheDC;
cacheDC.CreateCompatibleDC( pDC );
if( m_pBitmap == NULL )
{
m_pBitmap = new CBitmap;
m_pBitmap->CreateCompatibleBitmap( &cacheDC, m_ClientRect.Width(), m_ClientRect.Height() );
}
CBitmap* pOldBmp = cacheDC.SelectObject( m_pBitmap );
cacheDC->SetTextColor( RGB(0, 0, 255 ) ); //color blue
cacheDC->TextOut( "hello world" );
pDC->BitBlt( m_ClientRect.left,
m_ClientRect.top,
m_ClientRect.Width(),
m_ClientRect.Height(),
&cacheDC, 0, 0, SRCCOPY );
cacheDC.SelectObject(pOldFont);
cacheDC.SelectObject( pOldBmp );
cacheDC.DeleteDC();
//////////////////////////////////////////////////////////////////////////
But the text out is still black, what's the matter? May be I forget some steps?
I'm amumu, and you?

Your bitmap is monochrome. Change the 1st parameter in CreateCompatibleBitmap to pDC.

Aprt from what Tomas said, you should also be calling SaveDC() and RestoreDC(-1) on your cacheDC object. Although you select back in the original font/bitmap, you shold also restore the original text colour.
DC's should always be returned to the system in the exact state you got them. Thats why SaveDC() / RestoreDC() is so good for you in this situation.
CDC* pDC = GetDC();
CDC cacheDC;
cacheDC.CreateCompatibleDC( pDC );
if( m_pBitmap == NULL )
{
m_pBitmap = new CBitmap;
m_pBitmap->CreateCompatibleBitmap( &cacheDC, m_ClientRect.Width(), m_ClientRect.Height() );
}
caccheDC.SaveDC() ;
cacheDC.SelectObject( m_pBitmap );
cacheDC->SetTextColor( RGB(0, 0, 255 ) );
cacheDC->TextOut( "hello world" );
pDC->BitBlt( m_ClientRect.left,
m_ClientRect.top,
m_ClientRect.Width(),
m_ClientRect.Height(),
&cacheDC, 0, 0, SRCCOPY );
cacheDC.RestoreDC(-1) ;
cacheDC.DeleteDC();

I'm working on a project that uses multiprocessor computer. I want to use multithread teachnique for this and assign a specific thread to a specific CPU. I'm searching materials for my project. Please show me some if you know about this field.
Thanks a lot.

SetThreadAffinityMask does that.

Be careful though, the OS is pretty good at dividing your threads up between CPU's, and if you start trying to force a thread to a cpu, you may well in fact decrease your application's performance.

Jon is correct. You really shouldn't be assigning threads to a CPU. Unless you really have a very strong grasp of the ramifications, you are likely to degrade performance.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?
