我有一个用于 excel 的示例插件:我创建了一个对象 InDesign.Application
Dim myInDesign As InDesign.Application
Dim myDoc As InDesign.Document
Dim myPage As InDesign.Page
myInDesign = CType(Activator.CreateInstance(Type.GetTypeFromProgID("InDesign.Application"), True), InDesign.Application)
myDoc = myInDesign.Documents.Add
myDoc = myInDesign.ActiveDocument
InDesign 打开,但插件在以下位置显示错误:
`myInDesign = CType(Activator.CreateInstance(Type.GetTypeFromProgID("InDesign.Application"), True), InDesign.Application)`
错误内容:
Unable to cast COM object of type 'System.__ComObject' to interface type 'InDesign.Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{ABD4CBB2-0CFE-11D1-801D-0060B03C02E4}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
为什么?你能帮助我吗?
