How to store license text in program?

I'm writing a small program. When the program runs it displays the license terms. It's about 2 pages long. How would I store that in the program? Like in a string array? I don't want to have any other files other than the executable itself. I'm working in Visual Studio 2005 (C#).

You could store it as a string resource.

How to use GetPicturefromIPicture

Hello,

I am a bit new at this, but I have an active x control that has been converted to stdole.IPictureDisp, and I am trying to convert it to an image or bit map to display on the form. I thought the Axhost.GetPicturefromIPicture might be able to do it. But I am unable to get it to work. Would anyone have some examples?

Thank-you,
Kim

Hi,

i have an array of bytes i need to convert to a Korean string but i don't know how. I tried

char[] chars_array = System.Text.Encoding.GetEncoding(949).GetString(bytes_array).ToCharArray();<br />
korean_string = new String(char_array);

but it ends with square and ! ? characters.

Any idea Confused | :confused:

Where does the array of bytes come from? Have you tried different encodings, like UTF-8 or UTF-16?

Thanks it helped, i just found

 char[] array_country = System.Text.Encoding.Unicode.GetString(byte_country).ToCharArray();<br />
<br />
 string_country = new String(array_country);<br />
 MessageBox.Show(string_country);

works perfectly, the message box show the good string in Korean.

I then add the string to a listview, so is there any option to set to show the Korean characters in the listview?

*edit ok it's resolved the problem came from the font i used in the listview Poke tongue | ;-P

You may have to change the font that your listview uses to show Korean. There's a universal Arial font that has CJK characters.

By the way, I took your Korean characters and pasted them into a text file in VS2005 and saved it with 'Unicode - Codepage 1200' encoding. After the identifying BOM in the file, I get: 74 C7 C8 D0 AC B9 44 C5.

collection search

Hi, I a have a massive collection based on keys and values containing 500000 items.
the keys are int64 objects and values are strings.

My question is, if there is any collection type that allowes to search the collection keys (like for exapmle: finding the value of item between 1000 to 1002?), because meanwhile i'm storing it in a datatable and using the Select function to retrieve the datarow, which in this case takes a while each time, so if there is any collection which allowes to search, I'm sure it will be mutch faster.

Thanks.

If you are using .NET 2.0 or higher then try downloading PowerCollections from the codeplex or wintellect site.

http://www.codeplex.com/PowerCollections[^]

It has an OrderedDictionary class that can be used to extract key value pairs in a range, e.g.,

foreach(KeyValuePair<tkey, tvalue=""> pair in dictionary.Range(from, to)) { // (API simplified slightly)
// process pair
}

PowerCollections is dead easy to use. It's just a natural extension of the BCL generic classes.

I don't know what the performance will be like on your data size though.

There is another collection library called C5 that's more advanced but more difficult to use and less well documented.

Yeah it's quite cool, although I've not needed to use it in anger yet. But I'm aware it's another tool in the box should I need it. There's also the more powerful but more abstract C5 library.

I doubt you'll find anything faster and more flexible than a database... that's what they're for.

hi all,

Any ideas as to why the database is not being updated will be greatly appreciated!

It is driving me mad...and I just can't see what i am doing wrong Confused | :confused:

string dId = "Golden";
string dCharge = "150";

OleDbConnection connectDb = new OleDbConnection(db);
connectDb.Open();

OleDbCommand update = new OleDbCommand("UPDATE ShippingCharges SET Charge = ? WHERE ShippingID = ?", connectDb);

update.Parameters.Add("@ShippingID", OleDbType.Char).Value = dId;
update.Parameters.Add("@Charge", OleDbType.Integer).Value = dCharge;
update.ExecuteNonQuery();

connectDb.Close();

shouldn't the update command be "Update ShippingCharges set Charge = @Charge where ShippingID = @ShippingID" if you call your updateParameters like that?
