问题 Before knowing about Inno Setup used IzPack to do my installer, due to the need to verify if the port of the service that was about to create was in use, towards a query to the database with the driver jdbc, so if the connection was valid then send a error message to change the port. So this is the way I did before, but I do not know how to do it in Inno Setup: try { Class.forName("com.mysql.jdbc.Driver"); Connection conn = DriverManager.getConnection( "jdbc:mysql://" + server + ":" + port +

问题 I want to create a new About button at the bottom left corner of all the pages like wpWelcome , wpSelectTasks , wpInstalling etc; that will show some message if it is clicked. Message should close if user presses "OK". The button should show the full word "About" not like "Abou..." I have checked CodeClasses.iss file in Inno Setup, but I could not understand which piece of code I should copy, which should not. I have already seen these two post: Adding a help button to an InnoSetup wizard

问题 Is it possible to refresh the desktop using Inno Setup in the [Code] section? Either by using SendMessage or somehow use SHChangeNotify ? 回答1: You can call any function in the Windows API by calling it in the appropriate DLL. The Pascal DLL syntax is documented here. The documentation of the SHChangeNotify function is found at MSDN as usual. This function is found in Shell32.dll (no surprise!). [Code] const SHCNE_ASSOCCHANGED = $08000000; SHCNF_IDLIST = $00000000; procedure SHChangeNotify

问题 I have been trying for more than two days to get JPEG Image and MP4 Video File Information using MediaInfo.DLL in my Pascal Script.

问题 I wonder how to determine whether a specific Windows Update package is installed in the target machine, lets say for example the Windows Update package with name KB2919355 .

[Files] Source: {app}\*; DestDir: {app}; Check: IsPackageInstalled('KB2919355') [Code] function IsPackageInstalled(packageName):

问题 I have a batch file (setting changer) that uses xcopy to list specific files formats in a specific folder, then allows me to type in one of the names and the script uses that name to copy that file to another location. First xcopy creates a copy of the original as a backup ( rolling backup only 1 copy ) then does the file copy (extension is fixed in batch only body of filename needed This works great BUT I would love to try and do this in Inno Setup for a nice clean GUI. I would like to
