I'm using VS 2005 with Crystal Repors... have a report thats work perfectrly in may develop machin, but when publish it at the server machine the toolbar dosn't works, the bottons appears with a red "X" (cross image) and at try to print generetes an error... do you know how to resolve it?

Answer :
1. Find folder of aspnet_client\system_web\2_0_50727\CrystalReportWebFormViewer3\Images
2. If it doesn't found, just install crystal report redistribute.
3. Make sure in your root web in IIS has aspnet_client virtual directory.
4. If already has aspnet_client virtual directory, make sure that Physical directory contains images as images on step-1.
5. If there is no aspnet_client VD, just make step-1 as virtual directory.

Hope, this will help.
