I've been writing a chat client, which uses an extended RichTextBox as the chat area.
The RichTextBox takes simple XHTML code (including styles) and converts it into Rtf and displays it. This works great for almost everything.
The problem arises when you try to use extended UTF-8 characters, most notably Japanese Hiragana and Katakana, but also things such as the musical Sharp symbol or the interrobang symbol. These are being displayed as question marks in the RichTextBox.
They exist without problems in the input XHTML; and using a standard RichTextBox I am able to display them correctly. The problem arises when I insert them via the translated XHTML.
Does anyone know of a way that I can preserve the characters when converting to Rtf?

Hey all I have developed an application that makes use of the upnp.dll, but for some reason my application works fine on some computers but there are a select few that it doesn't work on and I get this error message:
System.Runtime.InteropServices.COMException (0x80070422): Creating an instance of the COM component with CLSID {E2085F28-FEB7-404A-B8E7-E659BDEAAA02} from the IClassFactory failed due to the following error: 80070422.
at [ApplicationName].ServerDetection.StartAsyncTypeSearch()
Can anyone shed some light on what is happening I can't seem to pin this error down.
Any help on this will be highly valued.
Freedom is the right to say that 2+2=5 if this is so everything else will follow.

Have you made sure the upnp.dll is registered when you install your app on the other computers. Try using regsvr32 on your problem machines.

Thanks for your reply Mark,
I've check and the DLL has definitely been registered on the problem PCs
Having a hard time tracking down this problem

Hi. Can anyone help me with understanding how to make a trial version of a program, e.g. it works for 10 days and then refuses to work, until user enters a serial key.
Is there an article about how to do that with examples in c# ? By "Examples" i mean pieces of code where the whole mechanism is written. E.g. how to generate keys. How to disalow user to use program for more than 10 days by simply reinstalling it ?
Thanks in advance

Most people do these though their distribution system such as Install Shield which take your applications binary files and wraps it's usage control around it...
I don't have an example of how this is done in C# but the methood would be to set a obscure reg key when it is first run that encodes the date...
Easy to crack though with a tool like "procmon" from sysinternals (you can see the reg key entry and delete or reset it to when it worked)
You could call it to goto the web but that can be spoofed (easy with %systemroot%/system32/etc/host) too...
Install shield isn't the best method, but will be harder to crack than most home made stuff...
as there are tools to "unwrap" install shield from a program...
best way to limit use on a program is have two versions. One with limited functionally, and another that is paid and have the program "track back" with in-program registration to verify the identity of the user. (CPU SN, Volume ID, and WMP user ID are good to build a GUID off of)

In my win-form, I am binding a textbox to a property, populated through my object. The property returns a number. Let's say 55.5
I want to add a % sign at the end of this 55.5 without changing the decimal or any of the significant figures.
How can i do it?
Here is what i know so far:
In the binding panel in the text property, under the "Format type" menu, there is a "Custom" option. It has Custom format textbox. If we put the % sign in here in a correct way, it will just be added to the end of the value of the property. So far, 0.0% or 0.00% has not worked as it changes the decimal and significant figures.
Any insight will be appreciated.

Are you adding this for a wildcard in SQL?
Or do you just want it to "display" with a percentage when they are done with the text box?
Do you want to show a confirmation with a percent sign?

I just want a "%" sign with the number to identify it as a percentage value.
|
|
|
|
|
Put a label next to the text box that says "%"
|
|
|
|
|
well this way, % would be always displayed even if the values have not come back. If, you have some method based on the form control, then that would be helpful.
Thanks

In your original post you wrote, "The property returns a number. Let's say 55.5" Would it possible to change your property from whatever "number" type it is (double, decimal, etc.) to string type? That way you could control the significant digits and add the '%' character to the end of the string.

You want to add a % sign as a suffix to the content of a textbox?
yourTextBox.Text += "%";

Thanks Vikram,
textBox name is txtPVSav
In the textbox property definitions, I added the following after the textbox binding code.
this.txtPVSav.Text += "%";
But the textbox content only displays the numerical value.

Ok guys,
I just figured this out.
In the binding panel in the text property, under the "Format type" menu, there is a "Custom" option. It has Custom format textbox. Add the 0.00 "%" in the Custom field.
This will append a % sign at the end of the numberical value and you will still be able to use that property as a numerical input to other parts of your program.
Thanks Vikram for initial headway

ArrayList temp = new ArrayList();
foreach (string var in Request.Form)
{
temp.Add(var);
}
This is the code I'm using to pull out the items in my form. However, I cannot seem to get the values of the data entered into the form. I'm just getting the names of all the objects in the form, but I really want the data as well. Am I missing something?

Request.Form returns NameValueCollection.
you should do this:
foreach (String var in Request.Form.Keys)
temp.Add(Request.Form[var]);
Hope I helped.

Hi All,
I have created a SQLBuilder class as a wrapper to the ADO2.0 SQLite implementation.
It uses refection for automatic database insert, update, delete and select.
Here is the link.
http://www.handymandy.ca/component/option,com_remository/Itemid,62/func,select/id,12/
Usage:
[dbTable("tblComputers",false)]
public class Computer2
{
private string m_Name;
private int m_Id;
private ProcessorType m_CpuType;
private int m_MemorySize;
public Computer2()
{
//connects to default database
SqlBuilder.Instance.connect();
}
[db(false,"Name","text","",false)]
private string Name
{
get { return m_Name; }
set { m_Name = value; }
}
[db(true, "Id", "int", "", false)]
private int Id
{
get { return m_Id; }
set { m_Id = value; }
}
[db(false, "Cpu", "int", "0", false)]
private ProcessorType Cpu
{
get { return m_CpuType; }
set { m_CpuType = value; }
}
[db(false, "MemorySize", "int", "0", false)]
private int MemorySize
{
get { return m_MemorySize; }
set { m_MemorySize = value; }
}
public void Insert()
{
try
{
SqlBuilder.Instance.verifyTableExists(this);
SqlBuilder.Instance.insert(this);
}
catch (ApplicationException e)
{
}
}
public void Update()
{
try
{
SqlBuilder.Instance.update(this);
}
catch (ApplicationException e)
{
}
}
public void Delete()
{
try
{
SqlBuilder.Instance.delete(this);
}
catch (ApplicationException e)
{
}
}
public void Select()
{
try
{
SqlBuilder.Instance.select(this);
}
catch (ApplicationException e)
{
}
}
}

Hello
Does anyone have an example of how to expose a C# EventHandler so that VBScript can hook up to it? It must be VBScript. I can call methods on this very basic class, but can't get the event hooked up. This is a Class Library and is built with the "Register for COM Interop" switch set.
<br />
public class Talker<br />
{<br />
public event EventHandler SomeNeatEvent;<br />
private System.Timers.Timer EventTicker = new System.Timers.Timer();<br />
<br />
public Talker()<br />
{<br />
EventTicker.Interval = 2000;<br />
EventTicker.AutoReset = true;<br />
EventTicker.Enabled = false;<br />
EventTicker.Elapsed += new System.Timers.ElapsedEventHandler(EventTicker_Elapsed);<br />
}<br />
<br />
void EventTicker_Elapsed(object sender, System.Timers.ElapsedEventArgs e)<br />
{<br />
if (SomeNeatEvent != null)<br />
{<br />
SomeNeatEvent(this, new EventArgs());<br />
}<br />
}<br />
<br />
public void ToggleTickerEnabled()<br />
{<br />
EventTicker.Enabled = !EventTicker.Enabled;<br />
}<br />
}<br />
Thank you for your time and ideas

Hello,
If I declare the following (or something like this....)
Graphics^ g = CreateGraphics();
Pen pen = new Pen(Color::Green)
g.DrawLine(%pen, 10, 10, 20, 20);
It won't work without the "%". Is this a "tracking reference"?
So my question is what is the "%" really doing?
thanks a lot

DisplayBitmap = new System.Drawing.Bitmap(camera.width, camera.height, stride, System.Drawing.Imaging.PixelFormat.Indexed, camera.MonocromeFrame);
This gives me an invalid argument (System.Drawing.Imaging.PixelFormat.Indexed)
DisplayBitmap = new System.Drawing.Bitmap(camera.width, camera.height, stride, System.Drawing.Imaging.PixelFormat.Format24bppRgb, camera.MonocromeFrame);
gives me the image but it is 3 times as wide and just repeats

tried
<br />
<br />
Bitmap temp = new System.Drawing.Bitmap(camera.width, camera.height, stride, System.Drawing.Imaging.PixelFormat.Format24bppRgb, camera.MonocromeFrame);<br />
<br />
DisplayBitmap = new Bitmap(temp.Width,temp.Height);<br />
<br />
for(int y=0;y<DisplayBitmap.Height;y++)<br />
<br />
{<br />
<br />
for(int x=0;x<DisplayBitmap.Width;x++)<br />
<br />
{<br />
<br />
Color c=temp.GetPixel(x,y);<br />
<br />
int luma = (int)(c.R*0.3 + c.G*0.59+ c.B*0.11);<br />
<br />
DisplayBitmap.SetPixel(x,y,Color.FromArgb(luma,luma,luma));<br />
<br />
}<br />
<br />
}
and it lagged beyond compare because it is a huge image.
The board retarded my for loops
here is a link to the code No Paste version of the code [^]
