If you are trying to use a cheeky file static or global variable while eagerly developing your C++\/CLI software you will probably encounter the following error:<\/p>\n
\n“C3145, global or static variable may not have managed type”\n<\/p><\/blockquote>\n
<\/div>\nAt this point you remember that this isn’t really C++ but a crazy non-standard extension to C++! So instead of declaring a file static scope variable like this:<\/p>\n
\r\n\r\nstatic Acquisition::IImage^ simage = nullptr;\r\n<\/code>\r\n<\/pre>\nSo as a fix, you can declare a container class and add it as a static member, thus:<\/p>\n
\r\n\r\nref class ImageContainer {\r\n public:\r\n static Acquisition::IImage^ Image = nullptr;\r\n};\r\n<\/code>\r\n<\/pre>\nAnd then access it in this way:<\/p>\n
\r\n\r\nImageContainer::Image = image;\r\n<\/code>\r\n<\/pre>\nThus solution worked well for us, but of course we will be getting rid of this global variable in due time! ;)<\/p>\n","protected":false},"excerpt":{"rendered":"
