Re: Clipboard paste formated text in Word - C# Discussion Boards

12-Aug-13 15:36

Hi, i managed to paste the text in word document, but the text loses text formatting (bold, italic, center justify). I followed this article:
http://www.neodynamic.com/ND/FaqsTipsTricks.aspx?tabid=66&prodid=3&sid=36[^]
What should i do ?

You could ask the author of the article.

Raw text does not have any formatting - it's just a string of characters. In order to paste data into Word, you can try copying it with formatting information using Clipboard.SetText with a TextDataFormat parameter: http://msdn.microsoft.com/en-us/library/tbfb3z56.aspx[^] - but if you are copying to the clipboard to transfer data, it's generally a poor idea - any app which messed with my clipboard like that woudl be uninstalled post haste.
There are generally better ways to transfer data between apps, including into word, depending on exactly what you are trying to achieve.

what you suggest, to create the word document while retaining the formatting? I have one Image componente and one Richtextbox.

Conditional question

Hi - I am trying to find the best conditional statement to use, to display a feature on web site.

I have a field from database which has a value 0,1 or 2. And based on what value this product has display different pieces of information.

I am using a case statement:

switch (value)
  case 2:
       value="message 1";
       break;
  case 1:
        value="message 2";
        break;
   default:
        break;

  return (value)

Is there a better and more efficient way to write this statement?

Thanks!

Why not put that in the database? Have a Message table and JOIN to it.

Try:

private string makeMessage(int value)
{
    // note that 'return is one valid way to exit a 'case block
    switch (value)
    {
        case 0:
            return "message: input is #0";
        case 1:
            return "message: input is #1";
        case 2:
            return "message: input is #2";
        default:
            Exception iEX = new Exception("MakeMessage: Input out of range");
            MessageBox.Show(iEX.Message);
            return "Kablooey !";
            // or throw the Exception?
    }
}

And, then test it like this:

string x = makeMessage(0);
string y = makeMessage(1);
string z = makeMessage(2);

string makeAnError = makeMessage(5);

More efficient" ? My understanding is that a switch-case block that uses an ordinal sequence of regularly incremented integer indexes is compiled into IL with maximum efficiency to essentially be a series of jump-table calls.

Your code will not compile as is because of a potential type-mismatch: so in the sense it can't possibly work now, as is, yes, it could be better Smile | :)

Assuming the variable 'value is an integer:

If 'value is an integer, 1, or 2, then a string is returned, but if not, then the compiler "sees" that potentially an integer value could be returned, which is why it won't compile: you "promised" to return a string.

The extent of input validation you may need/want to implement, imho, will depend on the certainty you have that that code will always be called with an integer argument.

If you are absolutely certain this code is always called with its argument taken from a database field which is guaranteed to contain an integer whose value is #0, #1, or #2, sure, your code is fine ... if you add in something to handle the case where the input is #0.

if it is really a number that has a fixed message attached you could put it in an array, list or dictionary. in that case you could do something like:

string [] msgarray = {"message 1", "message 2", "message 3"};

public string ShowMessage(int msgindex){
  return msgarray[msgindex];
}

the switch is not wrong, nor is this method "better" per se, but it might give you another look on things.
Hope this helps.

This is not a criticism of the general idea in your code example above, but your example does not match the behavior in the OP's original 'switch statement. It would also be far less efficient than a case/switch block.

There are many ways the OP's desired outcome could be implemented, but the OP's code is clearly flawed: it will not compile as is because of potential type-mismatch between the return type expected (string), and the input parameter value being: !=1 && !=2

Even if (the most unlikely hypothesis I can imagine) the OP had made the variable 'value of Type 'dynamic: the code would not compile: "A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type."

I see what you mean, but I don't think he meant for value to change from int to string, but rather made a typ-o.

Hi V., Yes, I agree: he either made a typo, or posted something incomplete (if it's in C#), but, most likely, as I realized later, he's posting JavaScript or some other weakly-typed language in this forum by mistake.

So, sorry if my response to you seems a little "picky." I'll leave it up just in case.

Looks like this would work for me.

Looks something of the form on enumeration.

I could not find a decent example using enum.

My messages have "html line breaks
" in them - how to set enums using HTML and text string?

Something of sort

public enum MyTest
{
"line break" = 0,
"This is test 1" = 1,
"this is test 2" = 2
}

Hi, the assumption here, since this is the C# forum, is that the question you ask, or code you include, is in C#, which is strongly typed.

If this is JavaScript, or another weakly-typed language, you might want to consider posting this on another forum.

Enums in JavaScript: well, you can get away with murder: [^]. 'Switch/Case in JavaScript: lots of examples on the web.

Here, in C#, we can only get away with suicide Smile | :)

But, that does keep us on "the straight and narrow." !

good luck, Bill

I'm unsure what enums have to do with anything. Enums are NOT text. If anything, they are more integers than anything else.
You can however parse text from and to an enum by using the, I think Enum.TryParse function. Enum names cannot contain spaces or special characters, as much as normal variables can't. So making HTML out of it is like translating the bible from ancient greek to chinese while being blind. $Shucks | :-\$

In short, since you seem to have "real" text (special characters and all), you're stuck with either string or StringBuilder. Whether you put it in arrays, lists, dictionaries, switch methods or any other form.

I have to agree to not agree on at least part of this.
Yes, you cant store just anything inside enums...
So, I see why storing strings in a enum is throwing a red flag...

But on the other hand you can use enums like this for simple text.

public enum Days {Sun=1, Mon=2, Tue=3, Wed=4, Thu=5, Fri=6, Sat=7};

Then you can store its value as 1,2,3,4,5.. and pass it..
works very good with view states for example.

Then you can take the value you stored...
and easily convert it back to a enum.

Days test = (Days)Convert.ToInt32(Value);

if (test == Day.Sun)
{
///do something
}

or you could print it out.. simple text..
string bla;
bla = (Days)Convert.ToInt32(Value).ToString();
