What handles dynamics:// URLs?

Question

I'm trying to create my own custom drilldown functionality, where a URL dynamics://0?myfunction_123456 will launch my own code.

In C\SysStartupCmd\construct, this base code:

    case 'viewalert':
        sysStartupCmd = new SysStartUpCmdViewAlert(s,parm);
        break;
    case 'drilldown':
        sysStartupCmd = new SysStartUpCmdDrillDown(s,parm);
        break;
    case 'viewalertrule':
        sysStartupCmd = new SysStartUpCmdViewAlertRule(s,parm);
        break;

I've tested and these all get fired with these URLs:

• dynamics://0/?DrillDown_382576
• dynamics://0/?ViewAlert_382576
• dynamics://0/?ViewAlertRule_382576

However, if I add my own case, leaving all other code the same, I can't get the URL to fire:

    case 'myFunction':
        sysStartupCmd = new SysStartUpCmdDrillDown(s,parm);
        break;

I've dug all over the system and can't figure out what causes the dynamics:// URL to only fire for those three cases. Is there a registry entry or something? I've found C\EventDrillDownPoller which appears to create a PipeServer to maybe handle what's incoming?

Answer 1

You have answered your own question, but it is quite easy (if you know how) to hook on the standard DrillDown code to customize AX to start a specific form like:

Starts AX on item 03310511 in company XXX

start dynamics://TEST/?DrillDown_0?table=InventTable&field=itemId&value=03310511&company=XXX

It will assume reasonable defaults.

start dynamics://TEST/?DrillDown_0?table=CustTable&value=113545

And AX can be called from a HTML e-mail, assuming the receiver has an AX client!

<a href="dynamics://TEST/?DrillDown_0?table=CustTable&value=113545">113545</a>

You find my customization in my pastebin.

Answer 2

Of course, I figure out my own answer every time I type up a stackoverflow question, but I think the information is really useful.

This stack question led me to find out that C:\Program Files (x86)\Microsoft Dynamics AX\50\Client\Bin\AxHLink.exe %1 handles Dynamics:// URLs.

Which led me to Microsoft's community forums where somebody else was facing a similar problem as me.

So the solution would be to either:

• Create custom a URI handler with C# or some other language to communicate to AX (Similar to this)
• Hi-jack one of the 3 handled existing cases with some custom X++ code to try and fork off of it. Perhaps by changing the drilldown target in the URL and handling that way, or appending some special characters to the string.
• Call "c:\Program Files (x86)\Microsoft Dynamics AX\50\Client\Bin\Ax32.exe" -startupcmd=myfunction_myParams and make that a clickable link.
