Hi Im not sure exactly what you want. You have your m_rect now do you mean that you want the resize bar inside the rect or that you only want to be able to move the rect to shrink (not enlarge).

If it is the first case use

m_tracker = new CRectTracker(rect,CRectTracker::resizeInside );

Here is how I used it to initilise my CRectTracker to move objects in my dialogs (warning untested code)

CDC* pDC = GetDC();
if (m_tracker)
{
	delete m_tracker;
	m_tracker = NULL;
}
LPRECT rect = new RECT;
CWnd* wnd = (CWnd*)(GetDlgItem(IDC_EDIT1));

wnd->GetWindowRect(rect) ;
ScreenToClient(rect) ;
 
m_tracker = new CRectTracker(rect,CRectTracker::dottedLine  | CRectTracker::resizeOutside | CRectTracker::hatchedBorder );
m_tracker->Draw(pDC);
delete rect;
rect = NULL;

You move the control inside all dialogue, and it is necessary for me to move the control only in what or parts of the dialogue limited m_rect.
All the same thank, for attention to my problem. If there will be ideas I with pleasure shall listen them!

Ive seen posts on the web saying that there are programs that can get the C/C++ code from an exe. Is this actually possible? It must be because what goes one way must be able to go back again.
If this is true could it mean the end of 'payed for' software?

.NET or not .NET? MFC is the question......

Yes, these programs do exist. However, the quality isn't very good.

I have taken software and created an ASM file before and then figured out how the software worked. In some cases it was to make sure my software acted as people expected (i.e. SendKeys from a C++ program). In other cases it was to get a full understanding of how a routine worked (i.e. VariantChangeTypeEx: when we were switching to it from a C based variant systems.)

Now...

The legality of a lot of this is VERY VERY VERY questionable.

Decompilation

As far as these things being the end of 'paid for' software, not in a million years. If fact, this desire for the end of 'paid for' software is actually very counter productive to the software industry. The quickest way to kill innovation is to make it all free.

Update for Microsoft eMbedded Tools 3.0?

Hi

I was wondering if anyone out their know of a sevice pack fixing bugs in Microsoft's eMbedded Visual Tools 3.0. I had to reformat my drive to get it out the registry the last time I installed it. Now I need to use it rather desparately but am feeling a bit off about reinstalling it. Did anyone else have problems with debugging in this environment? Much appreciated Hmmm | :|

I use it on W2K Pro to debug applications (and drivers) on iPac.
The debugger stinks.
Let me rephrase that:
The EVC debugger really stinks!!!
The debugger is SLOW and locks up all the time, then I have to kill EVC.EXE and reset my iPac.
I am desperate for an update, but to my knowledge there is none.
Why o why are there 5 service packs for Visual C++ but none for this CRAP!

Been using for months with no problems. Debugger works GREAT!!! (hehehe, see previous reply.)

However, I noticed a few things.

1. Don't use the emulator.
2. Get an ethernet card for your CE device. Otherwise the debugger is SLOW AS A DOG!!!!

1. the emulator when used for debugging applications works fine...
2. who do you think writes the drivers for the CE ethernet cards? I really have problems when writing this driver for a PCMCIA ethernet, a wireless LAN or a bluetooth card... I have to debug over USB (with the cradle).
Do you know a good kernel debugger for WinCE 3.0 iPac devices? I do not want to use the Platform builder and generate my own CE platform, since I need access to the already existing iPac platform.

Hi there,
Am trying to make an application in which i want to display data in form of tabs.I intend to use property pages.But i am not sure abt the number of the tabs at design time.Can i generate property pages dynamically and along with it can i add the caption as well as some components like grid control to it at run time itself.Am using VC++ 5.0.

Thanks in advance

collapsable text sections

6-Jan-02 23:44

hi i am searching a code snippet for adding 'little buttons' in a text file (i.e. shown inside a CEdit control)

before pressing the little button [-]
[-] function1
row1
row2
...
end function1

after:
[+] function1

the little buttons ought to be 'inside' the text, just to the left of the function blocks, so that when i wish to collapse the function code i can see only its name, on the opposite when i re-expand it, the whole function block

thanks in advance for any help

Re: collapsable text sections

6-Jan-02 23:54

because i am trying to write a little source code manager to let me 'concentrate' only on the open function blocks, but inside the text editor itself
if i would use a tree control i would have to 'transform' the source text into tree nodes whilei wish to work inside the text itself, ok?

Ok, I understand. Something like the VS .NET editor.
I wish i could help you, but I can't.
I hope someone else can help you.
My guess is they have written some kind of custom-edit control from scratch. They'll prolly release it as a control in VS 8.0

hello thank you for your post
actually i was almost sure that i had seen something like that here on codeproject or on codeguru (if not really what i ask something very close to it) but unfortunately searching intensively all the two sites (articles, forum etc.) i wasn't able to find what i am sure not to have 'dreamed' Smile | :)

hope somebody will point me in the right direction

thanks again for your help

Hi,
I have
BITMAP bm;
hImage = (HBITMAP)::LoadImage (NULL, gszPreviewFile, IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE |LR_DEFAULTSIZE|LR_CREATEDIBSECTION );
GetObject(hImage, sizeof(bm), &bm);

I will get the contents of bm.bmbits as fffff..
I need to get the proper buffer for that bitmap.How can do that?
Any idea?

Regards

I needed to do this also, but couldn't really find a way.

The way I solved my problem in the end (which might not be suitable for you) was to use the CBitmapDC class from this site. I used CDC::SelectObject to get the bitmap into the DC, then CDC::GetPixel() to retrieve my image data.

hope that helps

In theory, if you create a DIBSection, then bm.bmbits will be populated, but I admit I've never used it. I believe I read somewhere to make it work you need to pass in sizeof(DIBSECTION), but I could be wrong.

Dlls, Linking, Dynamic,

Tariq6-Jan-02 22:21

Tariq

6-Jan-02 22:21

Hi Guys,
Usually explicit linking of dlls is achieved by LoadLibrary & GetProcAddress.
GetProcAddresss is pretty neat in the fact that it can be casted to a function pointer, and used likewise.
My current understanding is the usual approach is to define a type for the function pointer and cast the return value of GetProcAddress to that type.

But supposing you were developing an application, where you have components (dlls) on a server,
and your application should donwload this components and automatically bind them. At design time you have no idea what the fuctions these dlls might contain.

I was thinking a small part of the dynamic linking can be solved by having the function signatures in an xml file to accompany the dll, but the how would you solve the other limitation, that is casting functions to a user-defined type, when you have no idea what the dll function would look like at design time?

Hope I have conveyed the problem clearly.

What are your views?
