ClickOnce application does not start through Process.Start(“x.abc”) with *.abc associated to the ClickOnce application

Question

I have successfully developed and deployed a ClickOnce application which registers an associated file extension, for instance *.abc. When I click on a file name

Answer 1

I've come up with a .BAT based solution, which is easy to implement. Say that you want to launch the ClickOnce application associated with *.abc files, then you simply put a file with the same name, but with the *.bat extension in the same folder, and then execute the batch file instead. Here is the batch script:

if exist "%windir%\sysnative\cmd.exe" goto :mode64bit

rem For a file named "C:\foo\xyz.bat", this will generate the corresponding
rem "C:\foo\xyz.abc" file, built as the concatenation of the drive (%~d0),
rem the folder (%~p0) and the file name (%~n0), plus ".abc":

"%~d0%~p0%~n0.abc"
goto :end

:mode64bit

rem When running in a 32-bit emulation environment on a real 64-bit system,
rem start the 64-bit version of CMD.EXE, and make if start the ".abc" file
rem for us:

C:\Windows\sysnative\cmd.exe /c "%~d0%~p0%~n0.xgen"

:end

This could be implemented directly in the caller of the *.abc files, but sometimes a batch file helps in the transition...
