No idea what kind of "end users" you have but my end users are Operations and
Support personnel. And they are specifically the people that need to edit the
Same kind. I've noticed they are often too retarded to manually edit config files, so I usually provide an easy to use GUI for them (or at the very least, send them a whole new config file they just replace the old one with). For applications that go out to end users, asking an end user to change a config file is asking for trouble. Your GUI should do all that.
I know where you're going next... web.configs, web services, etc. don't have GUIs. Well, for a production application, I usually have an admin app or admin portal that controls the system. Much better design.
Also, if you want a simple generic thing, you could do what I did. Have a simple property grid dialog that edits any config file generically and can pull in "documentation" either from an xml file or reflection.
XML can be unordered or ordered.
Entirely incorrect. The XML spec says specifically that attributes and siblings are unordered and can be returned in any order the parser wants. It just so happens that every parser returns siblings and attributes in document order, but that is NOT guaranteed. If you are relying on something that the XML spec says specifically is not guaranteed, I'd hate to be you when your ops team deploys "XML v17" which has some awesome performance optimization, but no longer returns in doc order and breaks all your stuff.
The proper way to do ordering in an XML file is by using a key.
I will admit however, that it's unlikely that a parser will start returning stuff in non document order, simply because some apps rely on that incorrectly.
The order however does matter when Operations/Support uses standard
difference tools to compare configuration files. Such as what they might do
when they need to install a new major version or point release and they want to
insure production machines have the same values with a new configuration file
and the old one.
What does this have to do with anything? .NET has this cool versioning thing that automagically updates your config files for you and adds in any missing attributes. Yes, I'll admit that the missing attributes may be added in a different order depending on code path (**UNLESS** you do it correctly -- in which case, the attributes will always be added in the same order).
Is that why you rolled your own .config file system? Simply so your ops team can run windiff on the files to make sure they are identical?
Seems like a proper implementation of upgrading the config files would be a better solution then re-inventing everything and having a non standard API, but thats just me.
See the first example which says "which must contain the following five elements in order"
which has some awesome performance optimization,
Yes the high volume tps servers that I have been delivering for the past 15 years do have measured and proven production performance abilities.
The proper way to do ordering in an XML file is by using a key.
The proper way is to understand more about what "XML" means.
What does this have to do with anything?
What it has to do with is documentation. Please read what I said. Trivial applications might have config values that are understood without documentation but more complex apps require substantial documentation so someone besides the original developer has any chance of understanding what the values mean, how they should be set, what the relationship between different values, etc.
...and having a non standard API, but thats just me.
Yes it is you, because I didn't say anything like that.
I don't know that the file should be stored in the user's documents directory, it doesn't sound like the right place.
I think a better place is APPDATA (APPDATA=C:\Users\Xxxxx\AppData\Roaming), then you can refer to it as @"%APPDATA%\dbs\latefee.sdf" and then use System.Environment.ExpandEnvironmentVariables before opening it.
Thank you all for dropping all this knowledge on me. It's been a while since I have done any coding, and I am not a programmer by trade. I am in IT for the company I work for, doing mostly tech work (very small business). I write small desktop apps for reporting from our POS system and use C# as I understood it most with VS 2003 (.net 1.1).
As I saw a need to update from XP to Win 7, I am trying to rewrite these programs with .net 4, so I am just now, as a few days ago, trying to learn the new IDE in VS 2010, the new classes and deprecated classes, etc, etc.
Thank you for your understanding and patience. Trying to google and study everything while taking calls all day for every problem from 'the internet is down' to 'this document is not printing correctly' is quite a task.
hi to all
i have a simple question please tell me,how can i close all methods by shortcut key and collapse all again.yes this is a basic question but i need it and i cant find this shortcut .thanks for help
I am new to DirectX and I am stuck in one basic scenario. So my requirement is -
I am having C# Windows Form. Now on top of that form I have to Slide one Image on top of another Image. Both Images are passed to my this translating class.
I used the concept of Sprite after going through the online Samples. But the problem is when the Sprite is moving the background is set to the color which is provided in the Device.Clear() method. I didn't find any way by which I can overcome this. There is no way to set the background image of the Device too.
I also tried using the concept of Microsoft.DirectX.DirectDraw.Surface too. PFB the code which I tried -
// Code Snippet Begin
SurfaceDescription description = new SurfaceDescription();
In fact, the Serial port can (and will, and does) send anything just fine.
The moment the external box starts sending us data, this method apparently stops and goes into an eternal loop on the last line.
Stopping the app in debug produces not a yellow arrow on the instruction (i.e., the last one in this method) but a green one instead.
Hovering over that green arrow produces this message..
"This is the next statement to execute when this thread returns from the current function"
I do not understand what thread the debugger has in mind, because I didn't start a thread. The only thing I can think of that even strikes the thought of the word "thread" in my mind is the background event handler that is doing the receive.
Just for good measure, I've set some breakpoints in the event handler that responds to bytes received on that same serial port, and it is properly receiving the bytes from the external box.
In fact, that's how we determined that conflict that was causing this. (We made the external box go silent; never sending any data, so this app can send without any response back.)
If it makes any difference, the send method and the receive method are in different classes.
No it doesn't. As I said, you need to separate the code into two threads, one for sending and one for receiving. At the moment it would appear that your code is single threaded, so as soon as your receive event becomes active, the sending code is blocked.
One of these days I'm going to think of a really clever signature.
I learned a thing or two at THIS[^] place, where that author provides this very useful insight...
"...The next part is critical and not obvious. serialPort1 runs in it own separate thread behind the scenes..."
(emphasis added by me).
This was really good and useful information, as you can see how it helped me to understand why I can't send and receive at the same time.
Request: I would like some kind soul to please point me to a few example code snippets that demonstrate how I can start a thread which will send out my byte array over the serial port when the existing background serial report receiver method/thread/whatever gives it an opportunity to do so.
