showModalDialog

Fandt selv ud af en løsning med dialogArguments.

Følgende stammer fra http://sure.org.ru/docs/html/html_reference/Scripting_Reference/windo.htm:


dialogArguments
The dialogArguments property returns any arguments that were used when the referenced modal dialog window was created. Note that this property only applies to windows created with the showModalDialog method. For example, if the following is used to open a modal dialog window:

self.showModalDialog "dialog.htm", "Enter search string"
and dialog.htm contains a text box (with an ID attribute of txtSearch), then running:

txtSearch.value=window.dialogArguments
would put the text "Enter search string" into the text box.
