Lately, I’ve been working on a project that has some pretty heavy duty encryption requirements. This stuff is very cool, but somewhat mysterious. I have run into these two errors and couldn’t really find a good description of what they are or more importantly, how to fix them.
Input too large for rsa cipher
Unknown block type
The problem is that without the code changing at all these two errors pop up all the time but very randomly. Read more
I’m not sure what the heck is really going on here, but for some reason, sometimes I can’t delete files and folders. I get an error message telling me:
Could not find this item
This is no longer located in E:\. Verify the item's location and try again.
One of the great promises of .Net was the escape of DLL Hell. While the .Net framework has reduced it from uncontrollable levels, any experienced developer can tell you it’s far from gone. Especially when you need to write code and then deploy it to multiple servers. Fortunately, there are tools that can help.
I have come across a situation recently where I am coding in DEBUG mode and things are working perfectly. When I go and try to get things running in RELEASE mode, I get an error.
Recently, a co-worker ran into a problem I had run into many times in the past. After taking a few minutes to figure things out I was able to help him. It surprised me that I hadn’t blogged about this before. So here we go…
Does this look familiar to you?
The type or namespace 'SomeNamespace' could not be found (are you missing a using directive or an assembly reference?)
I bet you’ve probably seen it before. It happens when you forget to include a reference in your project or if you don’t use a ‘using’ directive to include the assembly. Read more
I’m working on an MVC Website. In development in Visual Studio, things are working perfectly. My app needs to run in IIS. Easy enough, right? Just set it up in IIS and you’re off and running.
Recently though, my IIS instance of the site stopped working. What?! I began to get the following error:
HTTP Error 503. The service is unavailable.
Wha wha wha?! I checked IIS and it’s running properly. What the heck? SQL Server is okay. The thing works perfectly in Visual Studio. ARG. Read more
Recently, I’ve been working on a project that relies on a backend business object layer. The business object (BO) layer, requires authentication in order to be used. For most of the systems, this is okay, but my project is to be used by end users. We don’t need to authenticate the users… we need to authenticate the system.
This is easy enough using the CustomPrincipal object in Rocky Lhotka’s CSLA framework (which is also being used). We simply create the CustomPrincipal and add that to the ApplicationContext. Read more
There’s a commonly known piece of information that pretty much everyone knows… use it or lose it. It applies to foreign languages, computer language, cooking techniques… all sorts of things.
Things like the code to unlock restrictions on an iPhone! Read more
I got a text message from AT&T this morning. It was a courtesy message to let me know that I was approaching my monthly data limit. I only signed up for the 200Mb plan so 65% of that means that I’ve used up 130Mb. How the heck did that happen?!
It turns out it’s not that hard to do… especially when you update your applications just before you leave the comfy confines of work and free wi-fi. I began the application update while connected to the wi-fi at work, but then left for home. The phone dutifully continued to update the applications over the cellular network. Ooops! Read more
Everyone knows they should be backing up their data, right? Just like flossing and rotating your tires though, sometimes it’s easy to let it slip for a while. But for those of you that *do* backup your data, are you doing it right?
First of all, there’s really no excuse for not backing up your data now-a-days. External hard drives are really affordable and dead simple. Backup software is built into most modern operating system to make it as invisible as possible. If you’re not backing up your data, you must have some sort of obsession with tempting fate. Read more
