问题 I modified the MasterMan82's TIniFile code to read and write multi values from & to TEdit/TComboBox and TMemo. Forgive my vague questions, my english is not good. So, what I mean is: I have a couple of .INI files, A.ini, B.ini, C.ini ....and so on. I just store A.ini as a variable in the code. It is not possible to put all the file names in the code. When I opened A.ini, make some changes, click SAVE to save any changes made, and success!. Of course, because A.ini has been defined in the code

Not sure if it was my testing that has error, has anyone tested them before as well? I am looking for a Delphi Rijndael library that is able to pass the KAT Vectors test. Does anyone know of any such

问题 How Can I use embedded font or install new fonts in my firemonkey application? I tried this solution but WM_FONTCHANGE is not defined in FMX! I want to use custom font in my application, how I can do this? 回答1: I followed the instructions here, and they were of some help. I have a few extra hints that may help, The two inclusions that you will need to make this work is WinAPI.Windows and WinAPI.Messages. If you put these inclusions at the start of your "uses" clause, you're unlikely to have

问题 This line: TFileStream.Create(fileName, fmOpenRead or fmShareDenyNone); drops an exception if the filename contain something like ñ 回答1: You are, ultimately calling CreateFileA , the ANSI API, and the characters you use have no ANSI encoding. The only way to get beyond this is to open the file with CreateFileW , the Unicode API. You might not realise that you call CreateFileA , but that's how the Delphi 7 file stream is implemented. One easy way to solve your problems is to upgrade to the
