Hi all, I'm trying to create a little test application which reads chunks of a FileStream and appends it to a VarBinary(max) column on an SQL Server 2005 Express. Everything works - the column gets filled as it's supposed to, but my machine still seems to buffer everything into memory and I just can't see why. I'm using the following ...
I have a large-ish file (4-5 GB compressed) of small messages that I wish to parse into approximately 6,000 files by message type. Messages are small; anywhere from 5 to 50 bytes depending on the type. Each message starts with a fixed-size type field (a 6-byte key). If I read a message of type '000001', I want to write append its payloa...

This is not a new problem for me. From C to PERL to Python on Windows Mobile, Windows XP and other Windows versions this problem persists and f**ks my nerves. Now in my latest script it again happens. To be more concrete: I have coded in Python a trivial script. Now the script writes correctly to the file when run from the debugger, bu...
Hi All, I'm able to parse json files in MFC but is having a hard time modifying the values. Is there an easier way writing new values, other than converting it to native file types, modifying the contents and converting it back to json again? I thought it would be as easy as changing values in an XML file where you just look for the ta...

Hi, I'm building a blog for a client and they need to be able to edit a paragraph of text in the sidebar. I currently have it setup as a 'Better Text' widget which I can quickly edit for them. I don't want to give them access to the widgets, etc but they want to be able to edit it themselves. Is there an easy way to add a custom write ...
I am trying to write data from form inputs to a text file using PHP. The file seems to load correctly, but does not write the data. I have echoed the input values directly before trying to write to ensure they are not empty. The text file is in the same directory as the php file. I orginally got the error "Warning: fwrite(): supplied...

I am creating a prototype that will be run in a web browser. I would like to store (and retrieve) various info submitted by a user during the use of the prototype. I know I can retrieve a variety of file formats such as xml, json... and I know I can do local storage using the plugin jstore. So I suppose I can do a convoluted solution whe...
Hi, I'm using a C socket library I found online to implement a tcp socket data transfer program. Is it possible to make 2 threads share the same socket connection (1 read and 1 write), and have the read thread perform a blocking read and recv data while the write thread constantly writes data? All of the example socket programs I've se...

Do I need to authenticate or something similar? The second server that I need to write to is a windows server. Is this an issue? Thanks! ...
I've got a very similar scenario to the one described in this post. It describes how to load the contents of a file that contains properties & items, making sure they're resolved as part of the process. I'm doing the same thing except writing the contents away to another text file (generally .ini file). In short I'd start by importing a...
I am doing some performance tests for the amount of time it takes to write X amount of files to a specified location. I will be comparing write speeds: 1) with a custom file system driver installed and loaded, and 2) with the file system driver not installed nor loaded. I want to test this on various machines with various OS's. Also, I ...
We have written an application that performs small (22kB) writes to multiple files at once (one thread performing asynchronous queued writes to multiple locations on behalf of other threads) on the same local volume (RAID1). 99.9% of the writes are low-latency but occasionally (maybe every minute or two) we get one or two huge latency wr...

I'm not extremely familiar with IBM MQSeries, but I am writing c# scripts which write and read files from my queue server. The problem is my read works but my write doesn't. Please notice that I am using the same queue so don't bother going in that direction. My code firstly accesses the MQserver with the following code: MQQueueManager...
