large-files

问题 I'm currently doing some work on a silverlight LOB application i wrote for a customer.. When i deploy i can't help noticing how big the xap file is (4mb) and considering it's not a massive app it seems a little unusual. I am using the telerik silverlight toolkit (but only including the required themes - 2 I think).. There's about 1mb of images (which is maybe a bit too much for a LOB app).. Is this average for a silverlight application? Whats the average size of your xap files? How would I go

问题 I have a HTTP server which serves files in download, and some of these files are pretty large (can be 7 GB or more). When these files are downloaded from some networks, the connection is dropped and we find the following error in the tomcat catalina log: org.apache.catalina.connector.ClientAbortException: java.io.IOException: Connection reset by peer at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:393) at org.apache.tomcat.util.buf.ByteChunk.flushBuffer

问题 I tried to use write() function to write a large piece of memory into a file (more than 2GB) but never succeed. Can somebody be nice and tell me what to do? 回答1: Assuming Linux :) http://www.suse.de/~aj/linux_lfs.html 1/ define _FILE_OFFSET_BITS to 64 2/ define _LARGEFILE_SOURCE and _LARGEFILE_SOURCE64 4/ Use the O_LARGEFILE flag with open to operate on large file Also some information there: http://www.gnu.org/software/libc/manual/html_node/Opening-Streams.html#index-fopen64-931 These days

问题 Currently I'm using the following code snippet to convert a .txt file with XML data to .CSV format. My question is this, currently this works perfectly with files that are around 100-200 mbs and the conversion time is very low (1-2 minutes max), However I now need this to work for much bigger files (1-2 GB's each file). Currently the program freezes the computer and the conversion takes about 30-40 minutes with this function. Not sure how I would proceed changing this function. Any help will

问题 I have a ~600MB Roblox type .mesh file, which reads like a text file in any text editor.

问题 I would like to upload large files (~10 - 100Mb wifi or mobile network), but in background, because the user maybe will leave the app and later the system will close the app (if not enoguh memory) I created a service for this case but my problem is that when i killed the app the service restarting and the uploading start again. I found same problems without solution: keeping background service alive after user exit app My service is restarted each time the application is closed So it won't

问题 See also this question. Without knowing what I was doing, I enabled the largefiles extension, committed a file and pushed it to kiln. Now I know the error of my ways, and I need to permanently revert this change. I followed the guidance from SO on the subject; and I can remove largefiles locally, but this doesn't affect the remote repos in kiln. I have tried opening the repo in KilnRepositories on the Kiln server and nuking the largefiles folder (as well as deleting 'largefiles' from the

问题 I need to move the contents of every second line up to the line above such that line2's data is alongside line1's, either comma or space separated works. Input: line1 line2 line3 line4 Output: line1 line2 line3 line4 I've been doing it in vim with a simple recording but vim seems to crash when I tell it to do it 100 000 times...
