I want to label tick marks along XYgraph axes. The code fragment below will draw the tick marks along the x-axis. It will also draw the labels (i.e. -8.0 -7.0, -6.0 etc...) but I can't seem to get the tick marks and the numbers to line up. One problem is that when the labels float value is >= 0.0, the minus sign disappears and skews the label from the tick mark...
//Here is the code fragment
void DrawGraphXandYTicks(Graphics g)
{
Pen tickPen = new Pen(new SolidBrush(Color.BlueViolet), 1);
//Draw x-axis ticks.
float f = -8.0f;
PointF xtickPoint = new PointF(xIndent, yIndent + graphRect.Height/2);
Font labelFont = new Font("Courier",6);
SolidBrush labelBrush = new SolidBrush(Color.BlueViolet);
StringFormat strFmt = new StringFormat();
for(float fx = xtickPoint.X; fx <= graphRect.Width; fx += xtickPoint.X)
{
g.DrawLine(tickPen, fx, xtickPoint.Y - 2, fx, xtickPoint.Y + 2);
g.DrawString(f.ToString("f1"), labelFont, labelBrush, fx + 14, xtickPoint.Y + 4, strFmt);
f++;
}
Please Advise and thanks in advance

Use Graphics.MeasureString to find out how big your string will be, and then divide this in half to make the text centre on the tick mark.

Hello gurus,
I'd like to have a code snippet that shows how to detect which treenode has been double clicked in a treeview control?
Best regards.

Check for SelectedNode
this code will display node's text in Messagebox
private void treeView1_DoubleClick(object sender, System.EventArgs e)
{
MessageBox.Show(treeView1.SelectedNode.Text);
}

I'd rather use the MouseDown event and check e.Clicks = 2. It allows you do find out which button (DoubleClick is fired indistintly for left or right buttons.)
But the rest, stays the same.

Hi, I have a question, should we use Nunit for testing and at the same time avoid the TDD part, since TDD can be time consuming for short term projects.
Please your comments will be appreciated.

Hey I have this regex expression
"([\w\s]+)* ([\w\s]+)* West" <== 2 white spaces after *'s
that for some reason, when matched against the string
"Day Amount Direction3 100 West5 43 North5 44 North West7 54 South2 5995 East2 5995 North,Northwest 54 35345 543 North6 West"
Makes 3 regex engines i've tried (java and expresso, .net) crash or something. They just sit there and consume 100% processor time...
Does anybody know what's going on and how I can match this expression?
/\ |_ E X E GG
|
|
|
|
|
What part of the string do you want to match?
"Expresso" crashes as well.

|
|
Any character any number of repetitions a space any character any number of repetitions a space and "West"
That's what I want to match. It should get 2-4 matches depending on variables...
/\ |_ E X E GG
|
|
|
|
|
[^\s]+\s[^\s]+\sWest
Is this ok? It would match:
Direction3 100 West
44 North West
543 North6 West

Use this:
"\w+ \w+ West"
---
b { font-weight: normal; }

Hi everybody i got a problem in DLL and COM interoperability so could some one help me please !!!
I want to create a COM object in C# called conversion.dll
So I begin by creating Class Library project called “conversion.dll”
1-I add reference to a COM Object called “devise.dll”
2-When i compile the project a wrapper is created by VS.NET called “Interop.devise.dll”
3-i compile in VS.NET no problem and that’s great!!!
3-but to create the COM object conversion as I know i must add a key file called “conversion.snk”
So to create the file I go to prompt
Sn –k conversion.dll
5-i edit the file AssemblyInfo.cs in my project by adding
[assembly: AssemblyKeyFile("conversion.snk")]
6-I compile boooooom !! an error was generated
Message the assembly Interop.devise referenced is not a strong name !!!!!!
So how can I process to create the COM object conversion.dll knowing that the COM object devise.dll is alredy existing in the client Side..
Thank you in advance!!!!

You no need to add key file unless it is to be put in Global Assembly Cache. In the command prompt you just move to your project folder and then to bin\debug. Type the following in the command prompt
>regasm <yourcom>.dll /tlb:<tlbfilename.tlb> /codebase
Here the /codebase switch is important. It will set the code base in the registry.
Now, you will be able to access the component in com client.
