Error Message

This error occurs when trying to open a project:

Assertion:"ext.x > 0.0 && ext.y > 0.0" failed at line 448 of file..\glist\gsbar.c

Cause

The layout contains a corrupt scalebar.

Solution or Workaround

1. Make a backup copy of your .apr file.
2. Open the APR file in a text editor, such as WordPad or Notepad in Windows, vi or textedit in UNIX.
3. Search for the string ScaleBarFrame.
   
   This is how a scalebar is listed in the .apr file.
   
   

   
   (GSBar.11190
   	Name:	"ScaleBarFrame2"
   	Bounds:	11191
   	Sym:	11192
   	GView:	11175
   	Style:	3
   	Units:	4
   	Interval:	0.95000000000000
   	Intervals:	-4
   	TextRatio:	1.50000000000000
   	TextSym:	11196
   ) 

   
   

   Note:
   Notice that ArcView has numbered this scalebar as 11190. 

   
   
4. Locate the Layout that contains this scalebar.
   
   

   (Layout.17641
   	Name:	"Base Plot Layout"
   	CreationDate:	"Thu Nov 14 23:35:33 1996"
   	GUIName:	"Layout"
   	Win:	17642
   	CSMgr:	17643
   	Graphics:	17644
   	Dpy:	11185
   )
   
   (DocWin.17642
   	Owner:	17641
   	Open:	1
   	X:	148
   	Y:	13
   	W:	321
   	H:	272
   )
   
   (CSMgr.17643
   )
   
   (GList.17644
   	Child:	17645
   
   (GList.17644
   	Child:	17645
   	Child:	11175
   	Child:	11190 

   
   
   The Layout where the scalebar is located is called "Base Plot Layout".
   
   The scalebar is listed in the Layout's Graphic List (GList) as:
   
   

   Child:  11190

   
   
5. Remove this line from the GList.
   
6. Save the project file.
7. Open the project in ArcView.
