Hi,

Problem : with winmerge I can't compare xla files -- binaries files differs.

objectif : open xla files by automation excel in C#.
then with automation export every source files and launch winmerge to
compare them.

-- then I use this code :
this.excelWorkbook = this.excelApp.Workbooks.Open(
project.xla, vk_update_links, vk_read_only, vk_format,
vk_password,
vk_write_res_password, vk_ignore_read_only_recommend,
vk_origin,
vk_delimiter, vk_editable, vk_notify, vk_converter,
vk_add_to_mru,
vk_local, vk_corrupt_load);

it woks fine but only on xls files.
but the code I want to compare are located in xla files.
Is there a way to automation XLA files ?
