Hi there,
I can use Project Raster in arctoolbox to project a raster data correctly and one result raster image file was returned. The related parameters are showed in the following picture.
BUT, I program C# in VS2008 using the same parameters as the above. And, try to run it. There is no error information and no result returned! I am puzzled! The details is as followed
My operation system is WIN7, and the version of arcengine is 9.3. Any reply will be appreciated! Thank you so much!
