Many managers do not like this solution since it requires constant reformatting. My first reaction is to have the users save as CSV or TXT format. This results in the same problem of a file that is much larger than it needs to be and creates a situation where export reports is a long tedious process.ĭoes anyone know of a way around this large XML file size problem? The reports are generated very quickly but the export to Excel option also saves the file as an XML document. This problem only gets worse when we started looking at Reporting Services. For remote users the delay in downloading an 8 mb file is long. But if you open the file and do a "save-as" and change the file type from XML to XLS the file is compressed to 1 mb. For example, we have one report that results in an 8 mb file when saved to disk. One problem I have discovered is that the native XML format results in a large file when compared to a true XLS document. Response.ContentType = "application/vnd.ms-excel"

Using the below code sample I am able to allow my ASP.Net users to download reports to Excel. It is also possible that another user has a read lock on the file.Excel saves a file using three steps (if the file already exists in the target location):Creates a temporary file with a randomly generated name, such as 4CCA4100.Deletes the original file.Renames the temporary file to the original file name.If Excel cannot delete the original file or cannot rename the temporary file, this error message appears.To temporarily work a. This error appears if you have tried to save a workbook on a drive and you do not have Modify and Delete permissions to the location where the file is being saved.

Is there something that I should have done, but did not do? I installed XE4 first, registered it, then used I don't want to fool around too much as my environment is strictly controlled by IT, and they are very slow to do anything. The documentation says the FireDAC components should automagically appear in the tabset for Delphi. I purchased both from Embarcadero, and have downloaded both.

I am moving from a very old Borland product (2006) to Delphi XE4 Professional with FireDAC addon.

If my understanding is right, I can implement it that way, but just felt it need quite some extra code that seems not necessary, if the FireDAC can simply treat the first row in an Excel worksheet as data rather than field name!įireDAC and Delphi Pro XE4. I did a bit Googling, my understand is to use name range is like to use a pair of coordinates to locate whatever cell you want! is that right? I although have a lot relational DB (SQL) experience, but actually know nothing about Excel, except knowing it very powerful to create and work on tabular data set. Thanks for explaining what is name range to me. so basically I lost first row data in each of the worksheet. > My problem is that the first row in in each worksheet always read as filed > worksheet (ie: the the desired cell range)
