Hi,

Can someone tell me how to convert BOOL in to System::String* __gc

I'm really wired with this... Frown | :(

Thanks a lot.

I'm not sure I would ever ask such question, anyway, if I should, then I would ask it in the managed C++/CLI forum [^].

I'll join in the chorus of "wrong forum!".

But before you ask the question there, think about it yourself.

You have two things:

1/ A BOOL. This is a thing which has two states, true or false. 1 or 0. Orange or green. I use BOOL to represent whether something is on or off. So, it could also mean "Give Iain Money" / "Give Iain Kisses".

2/ System::String * is some weird thing from another language. But it sounds a lot like a string. (I know, I'm a genius with psychic powers). So, it would be some sort of text representation.

So, you need to understand what that BOOL represents before you can turn it into text.

Start this conversation:

CodingLover's Mum: "Darling, what does this mean when it's on?"
CodingLover: "Ah, it means __________________________"
CodingLover's Mum: "Darling, what does this mean when it's off?"
CodingLover: "Ah, it means __________________________"

But you're not done... Try this conversation also:
CodingLover's Swedish Girlfriend: "Älskling, vad innebär det när den är på gång?"
CodingLover: "Ah, it means __________________________"
CodingLover's Swedish Girlfriend: "Älskling, vad innebär det när den är avstängd?"
CodingLover: "Ah, it means __________________________"

Text is a pain - for some reason, people all over the world like to use their own language, instead of God's Good English!

Thanks for the comment. I'm not an experienced person in C/C++, and that's why I ask a question here, after different things workout.

Anyway, I'll try my best next time what you are saying in the above post.

Well, the answer to your question isn't really a "how do I write this code" answer, it's a "what does this mean / how do I represent it to the user" question, and that will be the same whether you write in VB, FORTRAN, C, ruby, etc.

In my miniscule experience, the hard questions are not coding ones, they are deciding what to code...

Good luck,

Iain

If you want to get a string value representing the BOOL, then this function ought to do you:

System::String^ GetStringFromBOOL(BOOL b)
{
   return Boolean(b!=FALSE).ToString();
}

This uses C++/CLR rather than Managed C++, which is why I have System::String^ rather than System::String* (^ is a managed pointer in C++/CLR).

The system command is a nasty thing. Use ShellExecute[^] instead.

::ShellExecute(NULL, _T("open"), _T("fcs.txt"), NULL, NULL, SW_SHOW);

Change the shape of CEdit custom draw?

Hi,

I've created CCustomEdit inherited from CEdit and managed to change its background color and text color.
I'm trying to change the shape of it ( eg : on each end i plan to make it like curve a bit rather than 90 degrees )

Is there any ways to change the shape of the CEdit ? Any tutorials/sample would be highly appreciated. Can GDI able to change the style of it?
My project is MFC based.

With thanks,
KarHong

Not only edit control, but the shape of any window can be changed by setting appropriate region. In your case, create a round rect region using the CreateRoundRectRgn() function and set that region to the edit control using the SetWindowRgn() function.

what place should i place the CreateRoundRectRgn() and SetWindowRgn() ?

I've try below code but it seems like the EditBox keep on blinking

CRect rcItem;
CDC* pDC=this->GetDC();
this->GetClientRect(&rcItem);

CRgn rgn;
rgn.CreateRoundRectRgn(rcItem.left, rcItem.top, rcItem.right, rcItem.bottom, 50, 50);

SetWindowRgn( (HRGN)rgn.Detach(), TRUE );

Thanks,

The PreSubclassWindow() function is a good place.

oh i'm using the pDC to draw the rectangle. That one I'm just testing out with the link given by Chandrasekharanp

I'm taking pDC out now and try your method.

But after i put below code, and execute it then the button went dissapear

void CCustomEdit::PreSubclassWindow()
{
CRect rcItem;

this->GetClientRect(&rcItem);

CRgn rgn;
rgn.CreateRoundRectRgn(rcItem.left, rcItem.top, rcItem.right, rcItem.bottom, 50, 50);

SetWindowRgn( (HRGN)rgn.Detach(), TRUE );

CEdit::PreSubclassWindow();
}
