SingleOutputMapAlgebra_sa "succeeds", but no output

[LeeBenda]

The same code works great on all of our computers, except one.  It runs SingleOutputMapAlgebra_sa from a VB-scripted Add-In, and throws an error.  I can find it in the ArcToolbox Results, and I can run it again from that prompt, where it says "Succeeded, elapsed time 0.0 seconds", and the output file does not exist.

I just went to the trouble to uninstall and reinstall ArcMap and Spatial Analyst, and it behaves exactly the same.

When I run Raster Calculator from ArcToolbox with the exact same input, it works. 

Any clue?

One of these computers is not like the other... time to play that game.

What is the error on your odd computer?

This is all I can get.  Is there a way to get more detailed error messages out of geoprocessing calls?

System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

When I specify gp.GetMessage(2), it says "Succeeded at (date/time). Elapsed time 0.00 seconds" and the output does not exist.

What does gp.GetMessages() say?

Probably won't be very helpfull though...

Would it be possible to "image" your odd machine as one of the others?

These sorts of issues are pretty quirky somethimes. I recall an issue a while back when I set my Raster AttributeLimit value(AdvancedArcMapSettings.exe) to be some large number like 999,999,999. Some (not all) Spatial Analyst tools freaked out and started bombing... Soon as I set it to a smaller number like 900,000,000 it stared working fine. As I recall, an ESRI guy could replicate the issue on only some of his machines.

gp.GetMessages() wants an argument for Severity....I'll try to figure out what to specify for that.

[LeeBenda]

I had it output all gp.messages: 

Executing: SingleOutputMapAlgebra Int(SetNull(C:\Data\app\vw\vmask2_app.flt == 0, C:\Data\app\vw\vmask2_app.flt)) C:\Files\Scratch\NTA #

That error is not very helpful!

000582 : Error occurred during execution.

Description

An error occurred during the tool's validation or execution. No specific messages were available. The validation process checks that a tool's parameter values are of the expected number, data type, and value.
Solution

Check that a tool's required parameter values are specified and are the correct data type. If the parameters are entered correctly, it may be possible that the execute routine for the tool is invalid. Have the developer of the custom tool check the Execute implementation.

The really weird thing is that this was working on this computer for the last month, and just quit working yesterday.

[ChrisSnyder]

Something changed.... And it's often pretty hard to figure out what it was...

I see you are using float files (.flt)... anything change in that regard?
