I am building a background processing engine which supports discarding both to-be-processed and is-being-processed items. This is for usage in a winforms application that will require heavy processing of some input elements, so I'm building a queue engine where I can enqueue workload items, and when they're processed, I get notified with...
The memory leak is not happening on every machine, but reliably on a couple at my work, and it's looking like close to 10% in the field. I have a product that uses a Windows service to monitor user input to launch alerts, paired with a visual application that serves only to sit in the system tray, and allow the user to make configuratio...
In Visual Studio, are there any real differences between a "Release" build of an application, and a published version of the same application? I have an ugly memory leak that's creeping up only in the published version installed via ClickOnce. The same leak does not occur in the "Release" build if I run the executable from the project/b...

Every .net developer knows about the concept of properties. A rough 99.99%, it's just a piece of metadata gluing together two methods, a getter, and a setter. Same thing usually goes for events, with their add, remove, and invoke method. The ECMA-335 describes a «Other» kind of method semantic, that would apply to either a property or ...

My program needs to download object definitions (basically xml files, maybe binary files) on demand via the net. The program will request objects from my server during runtime. The only thing the program has to send the server is a string that identifies the object it needs (e.g. RedCubeIn3DSpace23). So a basic Key, Value system. My app ...
I know that all arrays in .net are limited to 2 GB, under this premise, I try not to allocate more that n = ((2^31) - 1) / 8 doubles in an array. Nevertheless, that number of elements still doesn't seem to be valid. Anyone knows how can I determine at run time the maximum number of elements given sizeof(T)? I know that whatever quantity...
I have been searching for an hour on how to use FFmpeg from .NET and it seems you need to execute the FFmpeg.exe with a Process to get things done. To get a duration of an flv file for instance, you would need to start using grep to get something back out of cmd window. It all seems complicated... + you'd have to start installing things ...
I have recently set up Visual Web Developer 2008 Express Edition on my laptop (running XP SP3) to develop some c# .net code for a website. All seemed to be working great, I can edit code and the website runs in IIS... The problem came when I hit F5 to debug. I get the following error message: "Unable to attach to application 'WebDev.We...
I'm having a trust chain error when I receive my response in WSE 3.0. Their cert is fine when I grab the WSDL. Their cert is fine when I connect. It likes my public cert when I send the XML request. What WSE doesn't like is the token in the response. Microsoft.Web.Service3 calls getelement, then loadbinarysecuritytoken, but then check...

Is ...

Caching your data in your application code is generally a good idea for many reasons. We have being doing this for quiet some time in our shared environment which includes ColdFusion, .NET, and PHP. However, because we share this environment with many other development groups in our organization, there is significantly more downtime then...
Hi guys, I have some "input" that gets parsed a number of different ways. I'm trying to abstract out the parsing code from the various downstream engines that need the parsed result (some parts will display it, other parts actually execute it, etc. etc.). So far, I have this: interface IParsedNode { // Visits this node, returns wh...
