I understood you Christian. I think I confused you; I said "You think?" as in you would think they added the conversions just as Color. Sorry about that. I'll point at some one else and say we're with them. Hows that?

I'm looking for a way of taking an image file (bmp, gif or jpeg) and displaying or printing it with the same sort of quality that MS Word produces when the image has to be strected or shrunk. MS Word does some sort of dithering to make the edges fuzzy, whereas most stretch routines just lose/gain solid pixels.
Anyone got any code to do this or can suggest something?
Thanks,
Keith Worden

This looks like it might work for you:

For image display, I found in the past that <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmfunc_76if.asp">DrawDibDraw</a> does a fairly good job (smooth scaling, dithering...)

Look up the class CString in MSDN.

Use the Class CString and the function method Compare or CompareNoCase....
CString str = _T("Hello");
if(str.Compare("Hello") == 0)
{
AfxMessageBox("Equal");
}

Has anyone been able to get around the problem when using CBitmapDialog. The problem is that you cannot set the text colour of static controls.
Any help would be much appreciated.
Andy.

I guess you're referring to Joerg Koenig's <a href="http://www.codeguru.com/dialog/BmpDlg.shtml">CBitmapDialog</a>. If so, I think you only have to change m_HollowBrush creation code, which in the orignal code is
m_HollowBrush.CreateStockObject(HOLLOW_BRUSH) to something like
m_bkbrush.CreateSolidBrush(RGB(255,0,0));

Does anyone know where i can find an XML parser, so that I can store settings in an XML file instead of an ini file?

Is there a reason you wouldn't just use the Microsoft XML Parser, 3.0 (SP2) or 4.0?

Well, if he hates COM he can use Xerces, but MSXML is MUCH faster.

I have two object which i want treated the same.
A parent object is going to have a pointer member varible, which will either point to one of the objects or the other. I intended on achieving this by creating a header which defined a virtual interface from which the 2 objects inherit. Allowing the parent object to call standard member function present in both.
My problem is that one function present in both the child objects required different parameters.
How can i achieve this?
Cheers
Rich

Short answer is "cannot be done". if the functions accept different parameters, then they are not the same function, and you just cannot call them from the same virtual interface function.
However, there's probably a solution to your particular problem, but more info would be needed. Could you please ellaborate on which arguments are required in either case? How will the parent class determine which parameters to use, as it does not know the actual type of its member variable pointer beforehand?

Basically i wanted the parent class to be totally unaware of which child object was been used to achieve my task.
Seemed achieveable apart usingpure vritual interfaces apart from one parameter, it's a pointer to a 2d array in one of the object and a pointer to a string in another.
Guess my two option are:
* Use a void* and cast appropiately in each of the objects.
* Use an intermedia object which combines the two child objects.
Any other ideas? Think i am going to have to get my old uni notes out!
Thanks Again

* Use a void* and cast appropiately in each of the objects.
This is a no-no in OOP.
* Use an intermedia object which combines the two child objects.
Maybe, but I don't have a clear idea of your general scenario to be able to ellaborate mor on this approach. The basic question here is (IMHO): How does the parent object obtain the argument to its (of unknown type) child object? Depending on the various agents involved in the argument-passing thing, one of several design patterns can be applied.

Is there a way to enumerate through the list of available comm ports in the same way as you can enumerate through the list of printers?

Look for PJ Plaugher's library on this site. There is a function in there that will do this. There is a link to it in the left-hand column.

I'm currently having problems with inserting/displaying large amounts of items in a treectrl under XP. It seems that there is a limit on the amount of manageable subitems.
When adding more than 65.000 elements under one node (yes, i know thats too much to be useful for the user), the tree starts to behave strange: items disapear, nodes disapear, focus disapears, the scrollbar is not in sync with the content, etc.
All this under XP build 2600.
If you want to try, just create a simple dialog based application with a treectrl and add the following code into the OnInitDialog() function:
<br />
HWND hTree = ...your handle here;<br />
TCHAR buf1[64];<br />
TCHAR buf2[64];<br />
<br />
TVINSERTSTRUCT is;<br />
is.hParent = TVI_ROOT;<br />
is.hInsertAfter = TVI_ROOT;<br />
is.itemex.mask = TVIF_TEXT;<br />
is.itemex.pszText = _T("Root");<br />
<br />
HTREEITEM hItem = TreeView_InsertItem(hTree, &is);<br />
<br />
is.hParent = hItem;<br />
is.hInsertAfter = TVI_LAST;<br />
<br />
for(int i = 0; i < 5; ++i)<br />
{<br />
sprintf(buf1, _T("SubItem %05i"), i);<br />
is.itemex.pszText = &buf1[0];<br />
<br />
HTREEITEM hSubItem = TreeView_InsertItem(hTree, &is);<br />
TVINSERTSTRUCT is2 = is;<br />
<br />
is.hParent = hSubItem;<br />
is.itemex.pszText = &buf2[0];<br />
for(int n = 0; n < 1024*65; ++n)<br />
{<br />
sprintf(buf2, _T("Item %03i/%06i"), i, n);<br />
TreeView_InsertItem(hTree, &is2);<br />
}<br />
}<br />
And there is no difference between using CTreeCtrl::InsertItem or the SDK macro.
cheers
Andreas
