Is it possible to launch an application from a browser? I am not talking about opening a file from a browser (like open a PDF with Adobe Reader), but rather opening a new (blank) instance of an application that is installed on the user's machine.
Hypothetical situation: User browses a website that lists computers that can be managed via RDP. He clicks on a link to 192.168.1.10, that link opens Microsoft RDP client (mstsc.exe) with that ip address already filled out.
I am talking strictly about Windows universe.
Is that thing even doable outside of ActiveX and IE?
Is it wise to attempt this in IE with ActiveX?
The correct method is to register your custom URL Protocol in windows registry as follows:
[HKEY_CLASSES_ROOT\customurl]
@="Description here"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\customurl\shell]
[HKEY_CLASSES_ROOT\customurl\shell\open]
[HKEY_CLASSES_ROOT\customurl\shell\open\command]
@="\"C:\\Path To Your EXE\\ExeName.exe\" \"%1\""
Once the above keys and values are added, from the web page, just call "customurl:\\parameter1=xxx¶meter2=xxx" . You will receive the entire url as the argument in exe, which you need to process inside your exe. Change 'customurl' with the text of your choice.
