here something i found dunno if it means anything at all to us but hey its some good infoIssue
You want to use a button on a toolbar to open a drawing.
Solution
Create the custom button.
Right-click the button.
For the button name, enter Open Drawing ....
In the Help section, enter Opens drawing ....
For the macro, enter the following string:
^c^c_fileopen;"c:/program files/autocad/autocad2000/sample/colorwh.dwg"
Where "c:/program files/autocad/autocad2000/sample/colorwh.dwg" is the path to your drawing.
Note: Folder names are separated by forward slashes (/) not backslashes (\), and the path is enclosed in quotes because it contains spaces.
Issue
DIESEL (the language the menus and toolbar macros use) stops executing when it encounters a backslash (\). This can be a problem when writing a toolbar macro that includes the AutoLISP Newline control character \n. For example:
(setq a (getpoint "\nPick the point "

)
Solution
Use the TERPRI function in AutoLISP to create a new line without using a backslash to avoid problems with DIESEL toolbar macros.
This is how the TERPRI function would appear in AutoLISP:
(terpri) (setq a (getpoint "Pick the point "

)
Note: See related topics for more information about creating a toolbar macro.
