I have a .csv file that is frequently updated (about 20 to 30 times per minute). I want to insert the newly added lines to a database as soon as they are written to the file. The FileSystemWatcher class listens to the file system change notifications and can raise an event whenever there is a change in a specified file. The problem is t...
I'm pretty sure most of us are familiar with the concept of a project's requirements changing after it starts, this becomes more and more of an issue the less the client knows about how things work and the closer you work with them. How then can I design a system (specifically a website but general advice will probably be best here) so ...
I'm doing a project in a course at my university on distributed systems. I'm planning on creating something similar to Dropbox ( getdropbox.com ), but with some sort of non-centralized peer-to-peer twist to it. For this i need some method of detecting change in a directory structure. How do you think Dropbox do this? Their implementation...
I know that I can display a PDF file in my c# executable (not web app) with: private AxAcroPDFLib.AxAcroPDF axAcroPDF1; axAcroPDF1.LoadFile(@"somefile.pdf"); axAcroPDF1.Show(); But that is the regular pdf viewer like in the browser.

Most of our projects last a couple of months. At the start of the project a design is made but we generally find ourselves making changes or ...
I like Linq but find that once the designer has created my classes I have to modify them. Then when I change my database and recreate my classes in the designer my changes get wiped. For instance, let's say I have a class called Person. I create this class, add some non database related methods to it (outside of Linq) and then create a ...

Hello, I'm a beginner so if there is a terminology for what I'm doing I don't know how to search for it. So forgive me if this has been asked before. So here is what I do. Before I make any major code changes, I make a copy of the projects folder and call it "project v6" for example. Then if I really mess things up and cant find a way to...

For example: myEmployee.Department =...

Hi, I've been using git for a while for my one-man developments, but I haven't run into any tricky branching issues until now and I seem to have forgotten something fundamental that I no doubt "knew" just after reading the Pragmatic Version Control Using Git Book.. I'm often several releases ahead of what is actually published on my we...
