Once put a project using Crystal, in another development environment!
The project is running, and the picture generated by Crystal has become red x, nnd is nausea!
Later and well-running environment discovery, the new IIS website is missing a virtual directory under the root directory: CrystalReportWebFormViewer2 This virtual directory points to D: /Studio.net 2003 / Crystal Reports / Viewers /, is the directory I have installed a Studio.net development environment under!
I built a virtual directory in the new environment, pointing to the corresponding directory of the new machine!
Run the project again! Everything is OK!
