hi ,
i am trying to fetch the datafrom database into dataet and display it in a richtextbox in rtf format.
it displays a illegal file format.
please throw some light on where i am mistaken
below is the code for your reference
{
string st;
string st1 = "";
st = "select * from TPNeeds";
SqlDataAdapter ad = new SqlDataAdapter(st,con);
ad.Fill(dataset11,0,0,"TPNeeds");
DataTable dt = dataset11.Tables[0];
ArrayList arr = new ArrayList();
//Encoder e1 = Encoding.UTF8.GetEncoder();
Encoding encode = Encoding.Default;
foreach(DataRow row in dt.Rows)
{
st1 += row["NeedText"].ToString();
//richTextBox2.Rtf = encoding.GetString(binaryData,0,binaryData.Length);
}
byte[] rawBytes = Encoding.ASCII.GetBytes( st1 );
using ( MemoryStream ms = new MemoryStream(rawBytes) )
{
richTextBox2.LoadFile( ms, RichTextBoxStreamType.RichText );
}
// System.IO.MemoryStream stream = new System.IO.MemoryStream(StrToByteArray(st1));
// richTextBox2.LoadFile(stream,RichTextBoxStreamType.PlainText);
//richTextBox2.LoadFile(stream,RichTextBoxStreamType.RichText);
//richTextBox2.Rtf = encoding.GetString(bytearr,0,bytearr.Length);
}
catch(Exception ex)
{
MessageBox.Show(ex.Message.ToString());
MessageBox.Show(ex.StackTrace.ToString());
}
}
public static byte[] StrToByteArray(string str)
{
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
return encoding.GetBytes(str);
}

Is the data in the database a string in rich text format? Or is it a string in plain text format?

it's in plain text format
|
|
|

Then why are you trying to load it as RichText? Plain text should be set in the RTB as RTB.Text = plainText.

I am making a CustomLabel class which extends Label and abstract class CustomBehaviour. For some reasons the class is not an interface. How do you do this in C#? I can extend only one class at a time

What do you mean ?
|
|
|
|
|
I mean that I have two classes to inherit from, and I don't know hot to best do it. If the CustomBehaviour was an interface there would be no problem, bu it is an abstract class. I can't inherit from two classes, can I? And I wonder how to implement this.
|
|
|
|
|
Why can't you just have your custom behavior code inherit from the label class and then make all your new classes inherit from your custom behavior class? Thats how I do it!
Maybe I'm not understanding the problem though 
|

This is a class I wrote for my program's needs. It adds some methods and fields to Label. However, the case is how to make a class like MyLabel which inherits from Label and my class?
|
|
|
|
|
|
I came up with this:
abstract class AbstractCustomLabel : Label {}
abstract class AbstractBehavioralCustomLabel : CustomBehaviour {}
public class CustomLabel : AbstractBehavioralCustomLabel
{
public CustomLabel code
public override void OnDraw code
}
Is it acceptable?

hmm are you interested in writing converter Word (RTF) to PDF files? Or you just want tool to do that?
In latter case type "word to pdf" into google. Btw I use PDF Creator[^]. For documentation of school projects it's fine.

Hi,
I have a numer in a string that may or may not have a decimal delimiter and some numbers afterwards, e.g. 1234 or 1234,5 or 1234,567. Now I want to show this number to the user with thousand separators, and keep the decimal precision from the original number. I.e. the number should be 1.234 and 1.234,5 and 1.234,567
If I use the following code
NumberFormatInfo nfi = new NumberFormatInfo();<br />
nfi.NumberDecimalSeparator = ",";<br />
nfi.NumberGroupSeparator = ".";<br />
double.Parse(m_value).ToString("N",nfi);
I'll get 1.234,00 and 1.234,50 and 1.234,57 - which is not what I want. Is there any other way to just add the thousand seperators and leave the decimal things unchanged ? It seems that nfi.NumberDecimalDigits misses a "dont mess with it" number...
Any ideas ?

If I understand you question, then I think you've got your nfi.NumberDecimalSeperator and your ndi.NumberGroupSeperator contents backwards. Try switching the two assignments around and see if that helps.

You could use something like that ...
string m_value = "12347890123456789,57";
string strhi = m_value;
string strlow = "";
int DecLocation = m_value.IndexOf(",");
int StrLen = m_value.Length;
if ( DecLocation >=0 )
{
strhi = m_value.Remove(DecLocation,StrLen-DecLocation);
strlow = m_value.Substring(DecLocation+1,StrLen-DecLocation-1);
m_value = Separ(strhi)+","+strlow;
}
else
m_value = Separ(m_value);
private string Separ(string str)
{
int i = str.Length/3;
int maxlen = str.Length;
if ( i*3 == maxlen)
i--;
string newstr = str;
for(int j=1;j<=i;j++)
newstr=newstr.Insert(maxlen-j*3,".");
return newstr;
}

A variable is used in multiple threads. In a particular place, I am modifying the content of variable. So I am doing syncronization. in another place, just I am reading the data. Should I synchronize in the second place?
|
|
|
|
|
Just make a lock statment to the variable while any thread is using it till it finishes.
If I unserstood right?
|
|
|
|
|
Yes, you should. Locking the write operation only prevents multiple threads from writing to the same variable at once. If you don't protect your read operations, there is a chance that you might read in some inconsistent state when another thread is writing to the variable.

Hello
I'm using System.Windows.Forms.Label and I want to add some text, where one or more words are bold or italic.
I tried it with html tags but does not work. Somewhere i did read it should be done by html tags. I did it like this:
label1.Text="my <b>test</b> string";
In the output i can see the html tags.<
I hope someone can tell me how to do this.
Thanks
Roggey

Not supported by the label control. You'll either have to use multiple label controls for each word that is different (a messy solution), or come up with your own variant that supports it. The RichTextBox does support different fonts in the text stream, but is a rather heavyweight control to use as a label.
