Ximorro Posted June 17, 2011 Posted June 17, 2011 Thank you very much, Ward!I had solved my problem adding the size of the original data to the compressed binary (in my calling code, I didn't change the udf).But your compression library, and also the others about hashing and encription are something I add to my list of resources. Congratulations for your amazing work!By the way, this "Dll in Memory" udf only works in Autoit3.6, right?I tried it in v3.3 but nothing happens (I just fixed compilation errors, like changing OnAutoItExitRegister to the Option() mechanism in 3.3, but DLL functions are not called correctly). On 6/8/2011 at 6:53 AM, 'Ward said: Try my zlib UDF, uncompressed size is not needed.
ynbIpb Posted September 5, 2011 Posted September 5, 2011 Hi! I understand that I can use the UDF from Ward, but how do I use this library without the size of the uncompressed data? Or tell me another library (I'm interested in solutions DLL) Thanks.
ynbIpb Posted September 5, 2011 Posted September 5, 2011 Thanks asdf8, but I need to work with binary data Zlib with header: 0x789C Can you give me an example?
asdf8 Posted September 5, 2011 Posted September 5, 2011 There are examples application of the dll, nothing else, it can not
