Asp.net - Export To Excel File As .zip To Reduce File Size - Compress Xmldata Before Sending It To The Client?
Jul 8, 2010I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

View 2 RepliesFile I/O And Registry :: Export Data To Text File?
Mar 17, 2009I have a variable (double) that is constantly update in real time with data from an analog input. I would like to write this data as it comes in to a txt file. When I stop my acquisition of data from my analog input, I should have a txt file with all that data stored on my computer wherever I want it. The way I'd like that txt file to be laid out is like so:
Test Title: "This info comes from a string variable"
Operator Name: "This info comes from another string variable"
Test Date: "This info comes from yet another string variable"
[code].....
And so forth. As you can see I would also like to write the time for each data. This depends on my Timer interval which the user can set. The default is 50ms. So by default, y1 y2 y3 would be 0, 50, 100. How would I generate such a text file?
PS: I have five variables (X, Y, strTitle, strName, strDate)

I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..
