Exception after stand alone application was closed

MarkMindlin — Sun, 18 Mar 2012 15:13:24 GMT

We've created simple stand alone windows application, that have only one code string:

Geoprocessor pGeoP = new Geoprocessor();

After application was closed we get exception message (see the attachment)

All answer will be appreciated.

Have you tried releasing the object explicitly either with ComReleaser or MarshalComRelease?

ComReleaser did not help.

Do you mean Marshal.ReleaseComObject(pGeoP)?
If so, this gets exception "The object's type must be __ComObject ..."

I should stress that we use ArcInfo 10 SP2. But in 9.3.1 it was working.

One more thing - we use .Net Framework 3.5.

Sorry, I got confused with GeoprocessorClass which is a com class, Geoprocessor is a .net class. The first is part of ESRI.ArcGIS.Geoprocessing, the latter is part of ESRI.ArcGIS.Geoprocessor. Running SP3 with framework 3.5, I didn't get an error just creating an instance of the class and letting it go out of scope... I haven't used the Geoprocessor class since 9.2. Could be a bug at 10 SP2. I always use the GeoprocessorClass, the example seem written for this class (I believe it was new to 9.3.)

Are you doing license initialization? I have that line of code in an ArcEngine program running under version 10, service pack 3 without incident but I have an actual ArcEngine program that binds the license and ensures the runtime is available.

Yes, there is no doubt, that we use standart wizard to add License checking to the VS project.
In addition (as a support recommends) we added - RuntimeManager.Bind(product code); - as a first line in method Main(). In this case - we do our best. (?)

Lack of binding or license checkout would give you a different error. Do you have old versions of python hanging around? I had some problems with that and using the geoprocessing tools in the desktop interface.

Well, that is clearly more than one code string. Have you tried the application on a machine with a clean install? Have you tried moving to service pack 3?

What do you mean "clean install"? How can I do "clean install" on the users' desktop? It is not about 1-2 users 🙂

No, SP3 will be for our office only by summer.

Just because you have many users doesn't mean you can't take one test workstation and do some tests such as clean install or install SP3. Once you narrow down the problem or get a fix, you can think of deploying more widely. I doubt you have deployed a solution which declares one variable and instantiates it and does nothing else on all your users' workstations. If this sort of suggestion doesn't help, you should consider going to esri support for a definitive answer, this is just the forum, we are users too. But if it works at SP3 or SP4 or even 10.1, chances are they will tell you to go to that version.
