CodeProject has some classes you can download. First get the FileAssociationInfo, and from that get the ProgramAssociationInfo. The pai object can give you the icon. FileAssociationInfo fai = new FileAssociationInfo(“.bob”); ProgramAssociationInfo pai = new ProgramAssociationInfo(fai.ProgID); ProgramIcon icon = pai.DefaultIcon;
If you want to associate a program with an extension just add this instruction in your iss file : In the section [Setup] ChangesAssociations = yes ^-Setup will tell Explorer to refresh its file associations information at the end of the installation, and Uninstall will do the same at the end of uninstallation. And in … Read more
Sure you can. You were very close to answer in your comment to Jakob’s answer – If it is possible to change file association with environment variables – it will help, but it doesn’t seem possible. It is possible. All you have to do is to use REG_EXPAND_SZ type of registry key and environment variable … Read more
I wrote a small routine: public IEnumerable<string> RecommendedPrograms(string ext) { List<string> progs = new List<string>(); string baseKey = @”Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.” + ext; using (RegistryKey rk = Registry.CurrentUser.OpenSubKey(baseKey + @”\OpenWithList”)) { if (rk != null) { string mruList = (string)rk.GetValue(“MRUList”); if (mruList != null) { foreach (char c in mruList.ToString()) progs.Add(rk.GetValue(c.ToString()).ToString()); } } } using (RegistryKey rk … Read more
For brevity, I’m using a fake root key. In practice, replace Hive_Key with HKEY_LOCAL_MACHINE for system default settings, or HKEY_CURRENT_USER for per-user settings. Either of these keys are allowed to exist, or both. If they both exist, the HKCU key takes precedence. To associate an extension with a file type, you need to set the … Read more
Actually, @CrazyCoder is right: If you accidentally mis-labeled the file, PyCharm remembers it and sets a “pattern” for the new file based on the name. So go to Settings | Editor | File Types, find the type you accidentally mislabeled and remove it from the “Registered Patterns” list. For example, I mislabed “osm.py” as text … Read more
To register a new file extension with an application use the following defaults command. Replace PUT_FILE_EXTENSION_HERE_WITHOUT_PERIOD with the file extension i.e. txt. Replace org.category.program with the com/org name of your program i.e. com.apple.itunes. $ defaults write com.apple.LaunchServices LSHandlers -array-add \ “<dict><key>LSHandlerContentTag</key> <string>PUT_FILE_EXTENSION_HERE_WITHOUT_PERIOD</string><key>LSHandlerContentTagClass</key> <string>public.filename-extension</string><key>LSHandlerRoleAll</key> <string>org.category.program</string></dict>” Once you have added the file extension to the launch services, … Read more
Just write System.Diagnostics.Process.Start(@”file path”); example System.Diagnostics.Process.Start(@”C:\foo.jpg”); System.Diagnostics.Process.Start(@”C:\foo.doc”); System.Diagnostics.Process.Start(@”C:\foo.dxf”); … And shell will run associated program reading it from the registry, like usual double click does.
I think I solved this. For some reason there is a SECOND place in the registry (besides that shown by the file associations stored in HKEY_CLASSES_ROOT\Python.File\shell\open\command): [HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command] @=”\”C:\\Python25\\python.exe\” \”%1\” %*” This seems to be the controlling setting on my system. The registry setting above adds the “%*” to pass all arguments to python.exe (it was … Read more
When you execute a script without typing “python” in front, you need to know two things about how Windows invokes the program. First is to find out what kind of file Windows thinks it is: C:\>assoc .py .py=Python.File Next, you need to know how Windows is executing things with that extension. It’s associated with the … Read more
