Yes, many people could help you. All that Nelek's asking is that you clean up your post (not by creating a separate post) by removing all but the relevant lines of code. Folks here help for the fun of it so asking them to read through pages of unnecessary code is a sure way to get ignored.

O.K. I cleaned up the code, i hope i haven't deleted too much !
I tried to send as much info as it is possible sorry !

Is it better now ???

In The Doc.cpp:

Every click on the Fill button another value in the EditBix !
The On Fill function is in the Doc.cpp !
But this isn't working !

But what is not working? Have you used the debugger to step through the code? What happens in SetMyToolBarEditText()?

Re: filling an EditBox (which is embedded) in a toolbar by clicking a ToolBarButton !

14-Dec-07 4:45

Hi,

first i get a not declared identifier at ((CMainFrame*)GetParent())->SetMyToolBarEditText("blabla");

then i included the MainFrm.h in doc.cpp now i get :
: error C2660: 'GetParent' : Funktion akzeptiert keine 0 Parameter
: error C2227: Der linke Teil von '->SetMyToolBarEditText' muss auf Klasse/Struktur/Union zeigen

GetParent needs a hwnd but how can i get one ?

Best regards
Croc

P.S.: Are there tuts our there which explain the Prob whith an edit in a toolBat ? I can only find 1 or 2 tuts which discribe the usage of comboboxes. Or are ther perhaps sources / code snippets ???

Well, is SetMyToolBarEditText() a member of CMainFrame?

CrocodileBuck wrote:

That depends on which version you are using. To access the frame from within your CDocument-derived class, then you would need to use:

((CMainFrame *) AfxGetMainWnd())->SetMyToolBarEditText("blabla");

CrocodileBuck14-Dec-07 6:03

Re: filling an EditBox (which is embedded) in a toolbar by clicking a ToolBarButton !

14-Dec-07 6:03

now GetMainWnd is undeclared !
when i include CMainFrame ic get these errors :
: 'GetParent' : Funktion akzeptiert keine 0 Parameter
: Der linke Teil von '->SetMyToolBarEditText' muss auf Klasse/Struktur/Union zeigen

Well, it's only valid from within a CWinThread-derived class.

If I remeber rightly it's written into the default registry by Platform Builder when the build of CE is out together. That's where I'd start looking. I'm sorry I can't dig around and get you any more info but I've got DEADlines and all that. Smile | :)

Nothing is exactly what it seems but everything with seems can be unpicked.

What do you call the name of Win CE device?

See ::GetSystemInfo() and ::SystemParametersInfo() in your doc.

Add them by yourself. Choose what you need and go to the articles, there are lots of them than will help you if you read them.

Or just make a SDI document and take CFormView as the main View, then use CDialogs for the other things.

What is the simplest method I can use to get lines drawn on dialog boxes?

Thanks

Nelek13-Dec-07 23:59

13-Dec-07 23:59

pDC->MoveTo (x1, y1);
pDC->LineTo (x2, y2);

Simple enough?

thanks, it compiles but...

I keep getting into "Debug Assertion Failed!" can you advise me what is wrong with my code?

CDC* pDC;
pDC = new CDC();

pDC->MoveTo (0, 0);
pDC->LineTo (100, 100);

Nelek14-Dec-07 2:48

Nelek you missed a point!

14-Dec-07 2:48

You didnt associate the DC to a window. If you are in a dialog... one way to do it is:

void CMyDialog::OnPaint() 
{	CPaintDC dc(this); // device context for painting
	
	pDC->MoveTo (0, 0);
	pDC->LineTo (100, 100); 	

	return;
}

OnPaint is a message of the dialog, to get it go to assistant and look for it.

you have to replace -> with . and pDC with dc to make it all work! Poke tongue | ;-P

You cannot do that:
You have to request a device context to GDI.
That is usually done while handling the WM_PAINT message (you need to override the OnPaint method of your dialog), for instance:

void CMyDlg::OnPaint()
{
  CPaintDC dc( this );
  dc.MoveTo(0, 0);
  dc.LineTo (100, 100);
}

Create a really narrow static box?

That's what I do to put a line in between sections on my dialog boxes.

Using Draw Line needs a DC - which needs to be associated with a window. So you need to create one, and when do you do it? Lot's of little things to know - and by the level of your question, your knowledge isn't at that point yet.
