They both are same. If you are using first one, compiler will give error. But for second one, you will get error only in the runtime.

.doc is a proprietry format, you need MS word to access it. You may be able to do it with the free "word viewer" but I don't know.

In theory it's possible to reverse engenieer the .doc format and write your own parser to read and print it, but that won't be easy. OpenOffice have obviously done something like that as they can handle word files, so you could start by looking at their source code.

There may be 3rd party libraries out that that provide this kind of functionality (search google), but it's not built into .net as standard.

SerialPort class with inverted logic

User 1278216-Jun-08 16:07

User 12782

16-Jun-08 16:07

Hi all--

I've written a program to transmit data to a RS-232 device and everything was working fine. Now, due to design constraints, the device uses inverted RS-232 logic. I've tried to compensate for this by inverting my bytes before transmission but that doesn't work. Somebody here thinks that my stop and start bits also have to be inverted and thats why the microcontroller isn't picking anything up.

I'm over my head on this one, anybody have a clue if I'm looking the right direction or is what I'm saying sound stupid?

Thanks,
Aaron

Structs

I need some help again...

I need to create a Struct to pass to an Array, trouble is I have NEVER worked with structs. I am not even sure that this can be done. I have read about structs and my understanding about them are that a class uses the managed heap and a struct uses the stack, this makes for a LITTLE performance gain.

I also understand that you can create your own Value Types for example:

My Variable
{
private string myString;
private int myInt;
}

Theoretically this gives me a variable "Variable" that's of type string and int?? Am I in the right direction??

Thanks in advance!!

It's not true always. It depends on the context where you declare the value type variable. Read this[^]

What's an easy way to add Keys programatically?

That Asian Guy16-Jun-08 12:08

16-Jun-08 12:08

I am working with a component which requires a System.Windows.Forms.Keys value. Right now, the only way I know how to change this value programatically, through user input, is:

if (input == "a")
{
key = Keys.A;
}
// ... keep going

I am sure there is an easier way to do this. Can someone help me out?

Thanks in advance.

Is there a Keys.FromChar or something ? Is Keys an enum and Enum.Parse would do it ?

Well, if your in a Console Application then you can use ReadKey which can tell you the key that was pressed.

ConsoleKey thing = Console.ReadKey(true).Key;

The true means that the key the user pressed will not be printed onto the screen.

If you're in a Windows Application then set the forms KeyPreview property to true and use the KeyPress event which will have data on the key that was pressed.

You want to use the Enum.Parse static method

public static object Parse(<br />
 Type enumType,<br />
 string value,<br />
 bool ignoreCase<br />
);

Applying this method to your example goes like this:

key = (Keys)Enum.Parse(typeof(Keys), input, true);

Don't forget to sanitize the input value.

It doesn't always work (Unicode & foreign languages are the trickiest) but you can simply cast them:

key = (Keys)input;

Input has to be a char not a string. If you know your input will be a string but only one character long then you can use:

Keys output = (Keys)input[0];

Anyone else seen the new C# .NET CommandBars beta from Codejock? I think I like it :)

I was just doing some google searches looking for ways to improve the GUI of my C# app. I stumbled upon Codejock Software and seen they have some really nice C# components. Right now their CommandBars component is still in beta, but I like what I have seen so far. You can find the beta here: http://codejock.com/downloads/[^]

So what do you guys think of this? Should I use this? Any cons to using a third party component?

Thanks Smile | :)
