(DataFlex) Parse MIME to get Binary Data (such as GIF, JPG, or any binary file)Demonstrates how to parse a MIME to get binary data. This example extracts the image data for a GIF image to an in-memory byte array, and also to a file. This example uses a MIME test file located at http://www.chilkatsoft.com/testData/sampleMime2.txt. It contains the following MIME: Content-Type: multipart/mixed; boundary="------------080707010302060306060800"; This is a multi-part message in MIME format. --------------080707010302060306060800 Content-Type: text/plain Content-Transfer-Encoding: 7bit This is the plain-text body. --------------080707010302060306060800 Content-Disposition: attachment; filename="starfish.gif"; Content-Transfer-Encoding: base64 Content-Type: image/gif; name="starfish.gif"; R0lGODlhIAAgAPcAAP///+/v7/f39+/n5/fv7//39/fn597OzufW1tbGxs69vffe3u/W1salpZQQ EIQYEJwQCJQYCJwYCM6clL2Ee5wpGIwhEK0YANatpdalnHMYCKUhCJQYAKUYAM6Ec5QhCJwhCPfW zu/Oxta1rb17a6UhAK0hAPe9rb2Ec7V7a71rUpwpCL0xCJwhAOfOxta9tcatpdallM6cjMaUhK1C IZwxELU5EK0xCLUxCN61pcacjK1rUrVaOaVKKZxCIZwxCKUxCL05CLUxAM6llO+1nMZzUr1rSrVS KaVCGK1CGLVCEJQxCK05CLU5CIwpAKUxAK0xAM69tffWxrVrSrVaMbVKGMZKEL1CCLU5AP/v597O xufGtcallNaljLWEa96ce9aUc717Wq1aMcZjMbVaKbVSIa1KGL1SGJw5CK1CCLVCCMZKCM5KCMZC APfn3tbGvc57Ss5aGMZSENZaEL1KCM5SCLVCAMZKAPfezvfOte/GrdatlN6cc9aEUr1rOc5jIdZj GL1SEM5aELVKCMZSCNZaCL1KAOfOvc57Qs5jGNZjEM5aCMZSAN5aAO/OtefGrcZjGM5jEN5rELVS CMZaCN5jCOdrCM5aAO/Gpc5rGMZjENZrEN5jAOdrAOfe1t6MQtZ7Kd57IdZzGM5rEMZjCNZrCM5j ANbOxu/Wve+9jPe9hO+1e+etc85zGO+EGMZrENZzEM5rCN5zCO97COdzAO/n3u+1c+ecSt6UQs57 Ie+MIdZ7GOeEGM5zEO+EELVjCOd7CO+ECOd7AO/Ope+tWuelUu+UKeeMGOeEEO+MEOeECO+EAO/G jO+cKfeUEO+MCO+tSuecMeeUGN6MEOeMCO+UCO+tQuelOe+lMe+lKe+cGOeUEO+cEOeUCN6MAO+U AOe9c/e1Oe+lId6UEO+cCPe9Qve1Me+lEOecCO+lCOe1Su+1OeelGO+tGPetCPetAO+9Qve1GO+1 EPe9CPe9APf37+fv5/f//+/v9/fv9+fe5+/e5869xufW3t7GzgAAACwAAAAAIAAgAAAI/wABCBxI sKDBgwgTFgCwMKHDhwyHYWoIsWIBZsdyHaoIcaGbaNQ0ZeBYEROvV0pmCCDp8B4rZaOUcGHpcIEx aqPMYLjHMcsCAwgxkRv3q8wLnhAdfWpmDRwqAgQFEEvHLlCZNxwfpVmkDJ04dczc3LsXQtq4XWh8 aGH48F49FDUC9UInT941W6luCUOWyQmSLST3eUnChNS4c9SooQuGDNkrIIrA1MqXr0A+AyFC4Kln kMAQKljotJJGDZklS9PkyEHGLZu1ctbCmWvXThurfAbvHSii5kegxpYqtRpEKFnid/TSneu2LRYh P/0Q1tJRgYOZV71UL5LEK1KiV68yVf+xgaOKmAZICd5bmA8FEyZQlMjRRAhQGQv4QQSJL8ZLFHwP 6aFIJXNIEkggcgQhwYIlKEFFGDKcEgBCBVCkByC0IAMJGnSAYsUNEmzAgw4HBJBeQisZcAswjqGh wQeBKGIFFD0ocCJE9diyjTKRLPHBAx/cEAcdgxgx4Vg3HnSPKs4E00sNEYDwgQksQDLJIohMSJIj ugSTCRA/ILFDCjTckUkrpYiCAEluYCMLJCsoMQUM9gjQRSSL7CLJJjmQxMw3kQChxA78IFULHIK0 MgonXyR5UAHWVBKIEmEcUJAIYxgSSSF94AZRPrgsQgUF0RmUgWpy/LFmRYdMkACAANwrWA8cbAhi RZ8cjRWro0QEEsQVGTiKkLAM5QNGFWrAQFNLBIzABQPLRktQQAA7 --------------080707010302060306060800--
