Hello!

I'm new to U++ development; I admit this is a great tool, but I have a problem: compiling the BlueBar example, with either Windows SDK (for Vista - MSC8, or Win7 - MSC9) or MinGW (gcc 3.4.5 or 4.4.0) goes fine; running the program gives crash when clicking any of the toolbar's buttons (list, superscript, etc). The debugger finds the error in Callback.cpp which is:

#include "Core.h"

NAMESPACE_UPP

//#BLITZ_APPROVE
#define CPP_PART__
#include "Cbgen.h"

void Callback::Execute() const
{
if(action) action->Execute();
}

bool Gate::Execute() const
{
return (void *)action == (void *)1 ? true : action ? action->Execute() : false;
}

END_UPP_NAMESPACE

What is the problem? The source code is unmodified. U++ version 1952. I'd like to know how to solve this, i need it for a project.

Sorry, it is just a bug in the example.

Replace UWord constructor with this one:

UWord::UWord()
{
	AddFrame(menubar);
	AddFrame(TopSeparatorFrame());
	AddFrame(toolbar);
	AddFrame(statusbar);
	Add(editor.SizePos());
	menubar.Set(THISBACK(MainMenu));
	Sizeable().Zoomable();
	WhenClose = THISBACK(Destroy);
	menubar.WhenHelp = toolbar.WhenHelp = statusbar;
	static int doc;
	Title(Format("Document%d", ++doc));
	Icon(CtrlImg::File());
	editor.ClearModify();
	SetBar();
	editor.WhenRefreshBar = THISBACK(SetBar);
	OpenMain();
	ActiveFocus(editor);
}

(one line deleted) and it should work.

(The fix is commited to svn too).

Same modification must be in UWord-example and in other places.

It should have been fixed everywhere else some time ago. BlueBar was the last one I hope...

Thank you!

Although my post went on the wrong forum's section, you were very kind to answer.
