The February 2003 PSDK[^] is the last one that supports VC6. It does contain the GDI+ headers.

Hi!
I've created a DLL that can be loaded into several host applications. This DLL uses MFC and I have to have a non-modal window to send messages to it. In one of the exported functions of my DLL (where all neccessary initialization is taking place) I create my non-modal window with some code similar to this:
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
m_pWin = new CNonmodal(NULL);
m_pWin->Create(IDD_DIALOG1);
m_pWin->ShowWindow(SW_SHOW); That way my window exists until I destroy it during uninitialization.
So far, so good, this works fine when the DLL is loaded into another MFC application.
But now my DLL got loaded by a VB6 application and suddenly the non-modal dialog disappears when the first form of this application (the splash screen) is closed!
The VB6 application shows a splash screen, then loads my DLL (I can see my non-modal dialog popping up briefly) and shortly afterwards closes the splash screen (unloads the form). At this moment, my non-modal dialog also disappears and I don't have any idea why.
Can anyone help?
Regards,
mav

Unfortunately, I got no replies.
Fortunately, I finally figured it out for myself, so perhaps someone else can use this information:
Since I was creating the dialog without specifying an explicit parent window, the main application window was chosen. In the case of the VB application this was the splashscreen at this moment.
Once the splash screen was closed, all child windows were deleted as well.
At first I tried replacing new CNonmodal(NULL) with new CNonmodal(CWnd::GetDesktopWindow()), but that didn't help at all.
Still got no idea why.
Only after giving the parent window in the call to Create (m_pWin->Create(IDD_DIALOG1, CWnd::GetDesktopWindow());) it finally worked and the window didn't get closed anymore.

mav

I recently downloaded the XListCtrl demo and the "uxthme.h" and "tmschema.h" files are not there.
Also can someone explain where one is to place the "lib" files (in DETAIL please!).
I'm using VS 6.0.

These are in the Platform SDK, but as Christian indicated above the current PSDK is not compatible with VS 6.0. (I think you have to go back to 2002 or so to get one that is.)
Visual Studio 2003 and 2005 both ship with a compatible Platform SDK. If you are learning, I suggest biting the bullet and getting either. 2005 has a much better C++ implementation, but the IDE is rather flakey for C++ development. (Still, it's enough of an improvement that I use it for all of my new C++ development; I use 2003 only for legacy apps where it isn't cost effective to move to 2005.)
If you can get hold of a copy of the full MSDN CDROMs from at least October 2001, it will have the material you need on it (somewhere in the back of my mind, I'm thinking the February 2002 is the last that will work, but I may be remembering something else.)

Indeed you are. MSDN October '01 is the last one that works with VS6.

According to PJ's reference, the Platform SDK from February 2003 was the last one to support VC 6. (http://www.qmedia.ca/launch/psdk.htm[^])
PS. I don't have VC6 installed and have no way to confirm the accuracy of this site.

I ordered the Feb 2003 PSDK from that site in order to reinstall VC6 so I could maintain an old app of mine. The PSDK was free but they charged S&H to send out the CD.

True, as far as the PSDK goes. I understood your comment to be about MSDN.

Actually there are more than 100 dialogs and for displaying a static text on the top of the dialog i have to resize the dialog, accordingly i have to reposition all the controls in it.
can somebody give me solution to reposition controls without much work.

You can save alot of work by letting someone else do it! 
Does the text vary in length? If so then it's probably easiest to render the text yourself.
You're going to have to calculate all the text rects anyway so using static controls would just
add another layer of coding.
To calculate text draw rects there's GetTextExtentPoint32() (CDC::GetTextExtent() in MFC).
To draw the text (perhaps in response to WM_PAINT) there's DrawText() (CDC::DrawText() in MFC)

You could write a function that runs through all controls (except, perhaps, ones passed in an exception array) and move them. You'd call this from OnInitDialog, passing the window handle.

is it required to pass handle of all controls in a dialog for moving them?
if so itz quite a big task bcoz thr r more than 100 dialogs.
is thr ny better solution?

I think you misunderstood.
I suggest using David Crow's code (see his post below) as a starting point to write just one function that will cycle through the controls in the dialog, moving them one by one. (David's article shows how you can move the controls.)
This function would take the window handle of the dialog box and a pointer to the string (or a resource ID) that must be displayed. With that dialog box handle, you can calculate the size of the string and the delta for moving the controls. You then get each control in succession and move it. At the end, you add the static control for your string.
You would then call this function in OnInitDialog(). (Since m_hWnd--or GetSafeHwnd()--is common for each dialog box, the only variable is the resource ID or string pointer. Once you get this working for one dialog, it shouldn't take long to paste this in the rest and do the ID/pointer fixup.)

Hi!
I have a question concerning the use of delete keyword in C++ programs.
First, I do something like this:
int *pInt = new int [16];
delete pInt; All the documentation I have read about delete sais that you must use delete [] when the allocated memory is an array. But if I run the small program containing these two lines of code in Debug mode, the _CrtDumpMemoryLeaks function tells me that the is no memory leak. In conclusion, why is there any need to deallocate the memory pointed by pInt using delete [] pInt; if it works using only delete pInt?
If anyone can answer my question, I would greatly appreciate it!
Thanks in advance!

actually [] instruct compiler to delete the array of Memory block here.. if you use simple delete then only one memory block will be freed
