Working on a new version of iuiautomation and uia wrappers I needed a better way of getting my interface's Concept version 0.6 to generate based on idl file an au3 file with the definitions. As allways its more complicated then I thought ;-) due to small differences in the idl files on closing braces, separating inheritance colon inconsistencies in the idl tool that generates them so most likely its better to write a lexer/parser then the search/replace I do now Alternatives typelibinspector but could not generate them all at once aiowrappergenerator was generating for aio and not for objcreateinterface based on tli interfaces / xml but seemed incomplete Known issues Enums without given constant values to be filled in manually Enum adding fix first parameter to have a $ Empty interfaces fail on _ to be replaced with "" propput and propget deal with methods with same name Must be wrapped in main function $i counting to be done differently Working on the typedef's and replacements of identifiers in the string (some are replaced) enum automatically is a long typedefs are automatically assumed an int (which is not perfect but a start) struct like POINT pt is now generated as int Testing/debugging Choices done get_ and put_ prefixing only for put_ as that will have less impact on existing scripts that do not use get_ like ControlViewWalker, Current.. properties etc. So instead of Global Const $sIID_IUIAutomationCacheRequest = "{B32A92B5-BC25-4078-9C08-D7EE95C48E03}" Global $dtagIUIAutomationCacheRequest = _ "AddProperty hresult(int);" & _
