I would love to see this Grid Class in action. But with all of the files unzipped, when I go to modify the form, I get "Error instantiating cursor object! Can't find table testtable.dbf". I noticed that you updated your file project the other day, thought this might fix the problem, but it didn't. Did you QC this class before putting it out there for us???

You're right. Please download again or remove the table from DE. Dorin Vasilescu, November 21, 2006

Excellent class! Aaron Hudon, November 21, 2006

Terrific! But there is a slight problem with the left scroll bar. When the grid has more data that it can display, there is no visual indication of it. Also, it seems that the colums are set as non-movable. Victor Chigne, January 24, 2007

Hi again, There is a problem with this class when the data type chosen to sum is a currency. Can you take a look at this? Aaron Hudon, February 7, 2007

Hi Dorin, when use your class with SET POINT TO "," raise error. You fix this with SET POINT TO "." in CALCTOTAL method. Example: (at line 1) Local oldpoint oldpoint = Set("Point") Set Point To "." (at last line) Set Point To oldpoint Select(nworkarea) Gianluca Zanini, December 14, 2007
