I've been looking at Microsoft's Expression Blend[^] the past couple of days and have read this article : .NET 3.0 WPF Tools && Examples[^].
We currently have a legacy MFC based application that does a lot of GDI rendering. What I would like to be able to do is embed an Expression Blend composition within our application and dynamically control the properties of the rendering through the wrapping app.
E.g. The Expression Blend composition is showing a red car rotating and the user chooses blue from our app, I'd like to dynamically change the render to blue.
Has anyone looked at embedded any XAML based creations within their own legacy MFC based apps?
Thanks in advance.

can someone explain what im doiing wrong here:
<br />
HBRUSH backBrush = ::CreateSolidBrush(RGB(pLevels->frequency[0][0],0,0));<br />
<br />
HDC memDC = CreateCompatibleDC ( hdc );<br />
HBITMAP bitmap1 = CreateCompatibleBitmap(memDC,prc->left,prc->bottom);<br />
HBITMAP oldBitmap = SelectObject(memDC,bitmap1);<br />
<br />
::FillRect(memDC,prc,backBrush);<br />
::Ellipse(memDC,20,20,120,120);<br />
::BitBlt(hdc,0,0,prc->left,prc->bottom,memDC,0,0,SRCCOPY);<br />
<br />
::DeleteObject( backBrush );<br />
::SelectObject(memDC, oldBitmap);<br />
::DeleteObject(bitmap1);<br />
::DeleteDC(memDC);<br />
It just doesnt display anything.

Is prc->left what you intended as the bitmap width in the call to
CreateCompatibleBitmap(memDC,prc->left... ??
It's used in BitBlt too...

ceejeeb wrote: yes it is the width
If that's the case then how will this work...
::FillRect(memDC,prc,backBrush);
Are you sure you don't mean to use prc->right?

ahh yes my mistake it was menat to be right.
Now its draws to the screen but not as intended the back background is dotted black and white.

try changing
HBITMAP bitmap1 = CreateCompatibleBitmap(memDC,prc->left,prc->bottom);
to
HBITMAP bitmap1 = CreateCompatibleBitmap(hdc,prc->right,prc->bottom);
The default bitmap for a dc is monochrome - you want a bitmap compatible with the original dc.

I have a CTreeCtrl and an associated CImageList. Is there any way I can load images into the CImageList at runtime (e.g. from an .ico file supplied by the user) without them being hardcoded into the executable files ?

You can add/remove images from image lists dynamically.
Check out CImageList::Add() (::ImageList_AddIcon()), ::LoadImage(), etc.
Mark

Yes - although if dealing with a lot of images it is better to initially size the ImageList control to hold a bunch of images.
The CImageList::GetImageInfo(...) function or the ImageList_GetImageInfo(...) macro can be used to write data into the images maintained by the ImageList control.
Peace!

Note: you can dynamically load an image using the LoadImage API.

Yes you have many good function in CImageList Add,Remove,Replace

Thanks to everyone for the posts.
I know these functions, but they don't realy explain how to load icons from files or "external" data sources - this is what I meant by dynamic (the icons aren't already hardcoded as resources in the executables). I found the functions I was looking for, which are:
ExtractIcon() - load icon from disk
CreateIconFromResourceEx() - load icon from memory
Sorry, I think I should have explained what I was after a bit better..
cheers,
Neil

I think you need to SHGetFileInfo to get information about file and... and also if you dont know about CImageList and its functions search on the codeproject it has a lot of good articles

Good afternoon,
I would like to restrict access to Windows in my program. More especifically, I want to block some "key combinations" (Ctrl-Alt-Del, Alt-Tab, Windows key). Until now, I did not find anything to help me.
Can someone help me?
Thanks for the attention,

Maybe you can use SetWindowsHookEx(WH_KEYBOARD,...) and eat the keyboard messages.
|
|
|
|
|
But not all keyboard combinations are passed on by Windows.

I think a global keyboard hook can catch everything except the SAS . If not a keyboard hook, then a CBT hook can... I am pretty sure one of them can catch everything except the SAS ...

I'm drawing a blank....what is "the SAS"?
Thanks,

Secure Attention Sequence, which is what's required for access to Ctrl-Alt-Del.

My program has some keyboard commands I've got to keep.
I would like to block only those commands which allow access to Windows.
Anyway, thanks for your help.
