  • How to export large data to Excel

    - by mavera
    I have a criteria page in my asp.net application. When user clicks report button, firstly in a new page results are binded to a datagrid, then this page is exported to excel file with changing content type method. That normally works, but when large amount of data comes, system.outofmemoryexception is thrown. Does anyone know a way to fix this problem, or another usefull technic to do?

  • Send POST data with FBML on Facebook

    - by rebellion
    I'm new at this, and I can't seem to find the documentation that explains this. But I want to create a Facebook page, where you can send POST data to an external server, preferably with AJAX. Can someone please point me in the right direction, as I'm stumbling blind.

  • Adding Insert Row in tableView

    - by user333624
    Hello everyone, I have a tableView that loads its data directly from a Core Data table with a NSFetchedResultsController. I'm not using an intermediate NSMutableArray to store the objects from the fetch results; I basically implemented inside my UITableViewController the protocol method numberOfRowsInSection and it returns the numberOfObjects inside a NSFetchedResultsSectionInfo. id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section]; and then I configure the cell content by implementing configureCell:atIndexPath and retrieving object info from the fetchedResultController but right now I have a generic configuration for any object (to avoid complications) cell.textLabel.text = @"categoria"; I also have a NavigationBar with a custom edit button at the right that loads my own selector called customSetEditing. What I'm trying to accomplish is to load an "Insert Cell" at the beginning of the tableView so when I tap it, it creates a new record. This last part is easy to implement the problem is that I dont's seem to be able to load the insert row or any row when I tap on the navigation bar edit button. this is the code for my customSetEditing: - (void) customSetEditing { [super setEditing:YES animated:YES]; [self.tableView setEditing:YES animated:YES]; [[self tableView] beginUpdates]; //[[self tableView] beginUpdates]; UIBarButtonItem *customDoneButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(customDone)]; [self.navigationItem.rightBarButtonItem release]; self.navigationItem.rightBarButtonItem = customDoneButtonItem; //[categoriasArray insertObject:[NSNull null] atIndex:0]; NSMutableArray *indexPaths = [[NSMutableArray alloc] initWithObjects:[NSIndexPath indexPathForRow:0 inSection:0],nil ]; [self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationTop]; //[indexPaths release]; [self.tableView reloadData];} Before adding the:[self.tableView reloadData]; I was getting an out of bounds error plus a program crash and although the program is not crashing it is not loading anything. I have seen many examples of similar situations in stackoverflow (by the way is an excellent forum with very helpful and nice people) none of the examples seems to work for me. Any ideas?

  • Determine from where is "sh" being run under apache www-data user using using PF or NETSTAT

    - by Eugene van der Merwe
    I am working with a compromised Ubuntu 8.04 Plesk 9.5.4 server. It seems that a script on the server is continuously doing reverse lookups to random IPs on the Internet. I first spotted it during by using top and then noticed flashes of this coming up continuously: sh -c host -W 1 '198.204.241.10' I wrote a this script to interrogate ps every 1 second to see how frequently this script happens: #!/bin/bash while : do ps -ef | egrep -i "sh -c host" sleep 1 done The results are that this script runs often, every few seconds: www-data 17762 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17772 8332 1 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 17879 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' root 18031 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18078 16704 0 10:07 ? 00:00:00 sh -c host -W 1 '59.58.139.134' www-data 18125 17996 0 10:07 ? 00:00:00 sh -c host -W 1 '91.124.51.65' root 18131 17756 0 10:07 pts/2 00:00:00 egrep -i sh -c host www-data 18137 17869 0 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' www-data 18137 17869 1 10:07 ? 00:00:00 sh -c host -W 1 '198.204.241.10' My theory is if I can see who is launching the sh process or form where it's launched I can isolate the problem further. Can somebody please guide me using netstat or ps to identify from where sh is being run? I might get many suggestions that the OS is out of date and so the Plesk, but please bear in mind there are some very concrete reasons why this server is running legacy software. My question is aimed at a advanced Linux systems administrators who have in depth experience with security compromises and using netstat and ps to get to the bottom of it.

  • Automatic Data sorting/ analysis in Excel

    - by hkf
    I have data in the form of four columns. The first three columns represent time, value1, value 2. The fourth column is binary, all 0's or 1's. Is there a way to tell excel to delete time, value1 and value 2, when the corresponding binary value in column four is 0? I know this is a lot easier in C++ or matlab, but for reasons beyond my control, I must do it in excel.

  • Handling of data truncation in FUSE

    - by Vi
    I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not. Are them buggy or programs should not expect truncated writes and reads from the regular files?

  • Good ways to map a 2D side shooter (somewhat like liero, or soldat)

    - by Blaze
    I'm wondering what way would be best to render a 2D map for a shooter (these will be static maps) similar to Soldat. Multiple options I've considered are a tile based map (stored in txt files), or just creating different classes for the different terrains I plan to use and creating a data structure to read/store them in a file. (I want to also be able to include things like jumping/running on walls, sliding down walls/slopes ect) I feel like there must be a better way than either of these, but haven't been able to find definitive information :/ Thanks :)

  • secure data transport between web server and database server

    - by atypicalgeek
    I'm planning on provisioning a web server and database server in a server farm environment. They will be in the same network but not in the same domain, both windows server 2008 and the database server is sql server 2008. My question being, what is the best way to secure data in transport between the servers? I've looked into IPSEC and SSL but not sure how to go about implementing either.

  • [C++] Real time plotting/data logging

    - by Paul
    I'm going to write a program that plots data from a sensor connected to the computer. The sensor value is going to be plotted as a function of the time (sensor value on the y-axis, time on the x-axis). I want to be able to add new values to the plot in real time. What would be best to do this with in C++? Edit: And by the way, the program will be running on a Linux machine
