I'm implementing a model class that emulates a tree or hierarchy. A value is stored as a variant type structure, and you get access to a value with a key thats some unsigned int generated when you insert the value into the model. When you insert a value you specify a "parent" key.
So my question is: what's the best thing to use to implement this? Could I just use a std::map to store the key/values, and then a std::multimap<key,key> to store the parent/child relationships? Is there a simpler way?
Cheers
Jim

Does anyone know why on like 3 of 40 of the computers my company has, the controls placed on a dialog programmatically via MoveWindow are sized different than if they were just placed in the .RC file with the Resource Editor?
I have an image to show what I mean. On the right hand side I have what a normal machine looks like. on the left hand side is a screwed up machine( you'll notice all the top controls which are placed in the resource editor are much larger, where the bottom controls which are placed with MoveWindow function end up in the correct place)
http://www.john-moses.com/img/artviewer_bug.jpg[^]
So I have a dialog that has several controls on it, most of which don't need to be resized, only 2 of the controls on the dialog need to be resized. All the controls on the dialog that don't need to be resized I just place in the .RC file with the Resource Editor, and don't bother making member variables for. For the 2 controls that need to resizing, I'll place in the Resource Editor, but in the OnSize function I'll call MoveWindow on the 2 control's member functions to resize them.
This works just fine on like 98% of the computers are my company, but for like 3 people, for some reason this mix of Resource Editor/MoveWindow placed controls causes some kind of visual bug.
Any Ideas what could cause this?
I looked at the machines "Desktop Properties -> Display Properties -> Advanced", and all our fonts and sizes are the same.
We all do have different processors and video cards, nothing we can do about that.
We're all running Windows XP Pro
eh?

The coordinates in an RC file are expressed in dialog units. See here[^] for details on how to deal with them. Alternatively use place-holders in the .rc file and then use the GetWindowRect and MapWindowPoints APIs to get the coordinates in pixels (relative to the window's client area).

Oh thanks pal, you da man. I went for the placeholder like solution as it was quicker for me in this case, but next time I run into this (which I'm sure is soon), I'm going to follow the article.

I normally go for the place-holder solution myself.

Vs2005, XP Sp2. After reading lots of pages about MFC dlls and deployment and module state and memory and ..., here my question:
I have a plug-in dll, that is a "normal" Dll with MFC linked dynamically (and loaded by a third-party MFC app).
This dll uses:
- two resource dll, loaded at runtime (for changing language of dialogs) and that do not use MFC and do not contain code.
- two normal dll, delay loaded, with MFC linked dynamically.
- one win32 dll, delay loaded, with no MFC.
- one lib, statically linked, with MFC linked dynamically (actually this could as well be an MFC extension dll, I do not know the difference).
The whole makes extensive use of threads. Currently, this is compiled with the /MT option, as multithreaded (but for the lib, obviously). Should not everything be compiled as Multithreaded dll (/MD ?) Which Pre-processor definition are needed ? _DLL ? _AFXDLL ? _USRDLL ? What is the difference ?
When and in which projects should I use AFX_MODULE_STATE ?
Background: Debug version works perfectly, Release version is slow (some sync problems between threads probably). I came to suspect the project not to be build adequately, after observing that changing the thread priorities did not help. I also have one dialog that crashes when "DoModaled", supposely something goes wrong with state modules somewhere.
Thanks for your time, this bugs me.

Probably depends of your system memory since CString allocates the internal buffer on the heap, I suppose. but

does the above really make sense?

theoretically, up to 2GB.

What about the text limit of the CEdit control? The default limit is something like 64K iirc, have you set the limit of that large enough to view 120mb worth of text?

It depends on the OS. Win98 and before had a 64KB limit.

Then use a CRichEdit control.
That being said, it is horrible design to put 120Mb into an edit control

Perhaps you meant to reply to the OP.

Hello,
I am looking for a VC++ dynamic DLL loading sample without MFC class.
I work with Visual C++ 2005 Express, then I cant compile MFC.
I have found some articles about C++ dynamic DLL loading on Code Projet, but so fare all needed MFC.
Thanks,

Can you be more specific.

If you mean WM_COPYDATA when you say data copy, see here[^] for an example.

Transfer from where? To where?
