appContextOpenDocument() and acad.exe /ld myarx

[Anonymous]

Hi,
I wrote an arx which basically queues an initialization command with ads_queueexpr() while loading. Within this command (added with ACRX_CMD_TRANSPARENT | ACRX_CMD_SESSION flags), i want to open a DWG file. To do so, i check wether i'm in application context. If it's the case i simply call appContextOpenDocument(), otherwise i use executeInApplicationContext() and a helper to call appContextOpenDocument().

So far everything works fine. I'm happy.

Then i tried to use /ld switch to load my arx when acad.exe loads. Everything is still ok. My document is opened and i can work as i want.

Till now i used AutoCAD 2006 english, but my customers use AutoCAD 2006 italian, so i tested it with italian version and it's still ok when i load my arx manually, but as soon as i use /ld switch appContextOpenDocument() returns eFilerError.

So I formatted a test computer, installed both italian and english AutoCAD on the same machine. English works fine with /ld, but italian fails.

I even tried with the french version which fails as well. So i'm wondering if there is any difference between "original" and translated AutoCAD.

Any clues about this weird issue ?

Thanks !

I submitted my little worry to DevHelp. They admitted there is something wrong with AutoCAD. Here is a quote from their reply:

So i'm waiting 🙂

I had no news from AutoCAD about this issue.
So i found a workaround. I had to write a loader, a small executable written in C# in my case, who does following steps:

1- write some keys in registry to autoload my ARX when AutoCAD loads
2- launch AutoCAD
3- wait a few seconds
4- remove the keys i wrote in registry (to allow AutoCAD to be launched without my ARX)
5- quit the loader

You may find more information about what keys to write in ObjectARX Reference by searching "Creating AutoCAD Subkeys and Values".

It's not a really nice solution, but it works fine for me.
