Hi! I am developing an Intranet web application with which I will show Excel output. This works fine in most cases but now I have run in to some problems on one of my test computers. Since it works on other computers I am fairly sure that it is not my web application that has a bug in it, but that it has to do with the operating system or the Office packge (Excel). Then I am to view the excel data from the web application I get a system question if I want to open it directly in the web application or if I want to save it as an .xls file (so far so good). I have no problems if I save it as an .xls file and then opens that file with Excel outside of the web application. That works fine. But when I choose to open the excel data in the web application I get two error messages: 1. ****************************************************** "Microsoft Excel" Could not open 'res://C:\WINNT\system32\shdoclc.dll/dnserror.htm ****************************************************** 2. ****************************************************** "Microsoft Excel" Microsoft Office Excel cannot access the file 'res://C:\WINNT\system32\shdoclc.dll/dnserror.htm'. There are several possible reasons: -THe file name or path does not exist. - The file is being used by another program. - The workbook you are trying to save has the same name as a currently open workbook. ****************************************************** and then nothing more happens. In my own tests I have discoverd: 1. That it seems to have somthing with the size of the Excel data. If I go over a certain amount of excel data I get the error otherwise it works fine. 2. If I first starts the Excel application separately and after that tries to get excel data from the web application the error messages pops up in the Excel application. After that I have dismissed the messages the excel data flashes by for a briefe second in Excel and then it is gone. 3. As I mentioned before. There are never any problems if I choose to save the excel data as an .xls file and then opens that file with Excel separately outside of the webapplication. The computer environment: - Windows 2000 Professional. - Internet Information Server 5.0 - Microsoft Office 2003. - Internet Explorer 5.5. - F-Secure (Virus protection. In the tests I've tried to close it down with no effect). - Zone alarm (Firewall. In the tests I've tried to close it down with no effect). The web exist on this computer and it is on this computer I get the error. However then I connect other computers to this computer and tries to view the excel data in the webapplication it works fine. Hope anyone can help me with this. Best regards, Johan
