hi all,
i want to ask my question with this illustration:
i have a pen object. then color property (typeOf(String)) of this pen can be "white", "red"... and it possibly can change. and i don't want to save it into the database but it needs to be managed at runtime.i.e a combo box will pick its items from it and an admin can (using a UI)change thye available colors. can i save this enum in the config file? how do i save at design time and how do i modify at runtime?
Thanks for any suggestion

You can serialise any item, so long as it's marked as serialisable, and can be rendered to and from a string. An enum will be fine in this regard.

Thanks. But i think you are getting my question wrongly.
A pecil object has a Color property, TypeOfEraser property, Thickness(H,HB,B..) property..
Each of these properties are enumerable: Color.White, Color.Green...; TypeOfEraser.Big,TypeOfEraser.Red...; Thickness.H,Thickness.HB...; and these enumerations can be altered by an administrator of the app. rather than pull/push these values into an SQL db, i ask if it is better to save them in a config file. Now this means i'll have to be able to read the config file at runtime and persist changes too.
please how do i go aboout this?
thanks

As Christian said, you can serialize your object (Pencil in your case) to a file and read it back without writing any custom code.
Just mark your class with the [Serializable] attribute and you're ready to go. You need to make sure that types of member variables (and their members, essentially the whole object graph) is marked as [Serializable]. <code>Enum</code>s are serializable , so you won't have any problems there.

set axWindowsMediaPlayer1.URL= "Address of your mp3 or audio file" to run the mediaplayer.<br />

They are part of the DirectX SDK. You'll need to download and install it.

Gee, does it LOOK like what I said ?
I recommend in future if people give you advice, you take the terminology they use and google it. You still need to download the DirectX SDK. .NET framework and DirectX are two different things, that's why they are spelled differently.

What method in C# to View Text File ?
Thanks !!
|
|
|
|
|
View a text file? You mean launch a .txt file with the program currently associated with .txt files? That would be System.Diagnostics.Process.Start. Or do you mean show the contents of a text file inside your own Windows Form? For that, you just need to read the text of the file in using System.IO.File.ReadAllText, then put that text into a textbox on your form.

Thanks !!
Can U give me any example?
|
|
|
|
|
Can you first tell me what you're trying to do? Are you trying to launch a .txt file or show its contents in your own form?
|

Does that mean that your form launches a new form that shows the file, or do you want to view Word and Excel files within your app ( that is, within your program window ) ?

OK - I thought so. This will become possible with the new XML formats for Office 2007, in the meantime, the best you can do is to use COM or ( for the newer versions ) .NET to embed/control Excel/Word within your app. It can't be done so that it works for PCs without office installed.

Hey guys,
My question is simple. How do I delete repeating characters? Say I have the string "Hello World" and after deleting ALL repeating characters (not just adjacent ones) the new string would be HeloWrd. I'm thinking of using a nested 'for' loop to compare each character to the one after it, but it's not working. Here's what I have so far... I appreciate your help!
for(i=0;i

Use the "Ignore HTML" option when you post code that contains <. Now half of your loop statements are missing.

And another thing: Why should the space be removed? It's not a repeated character.
---
b { font-weight: normal; }

This is what I came up with, but I only tested it with the "Hello World" and "This is a test" sample so far.
Please test it with different strings
string test = "Hello World";
StringBuilder b = new StringBuilder(test);
int removeCount = 0;
for (int i = 0; i < test.Length; i++)
{
if (test.IndexOf(test[i]) != -1 && i > test.IndexOf(test[i]))
{
b.Remove(i-removeCount, 1);
removeCount++;
}
}
test = b.ToString();

Hi!
You could serialize it using a BinarySerializer and then convert the byte[] into a base64-encoded string that's written to the XML file.
Reading is simply the other way 'round.
