this is a little bit tricky. write a wrapper for the function, what you want to use, using C++ .NET. Create that wrapper as a .NET DLL. Then add reference from C#. But it is not so easy, it is not for beginner.

You would add a reference to the taglib-sharp.dll to your project.

How to set the x & y axis fontsize in MSChart

I am having a problem setting the x & y axis fontsize in MSChart. I have played with the settings through the properties window, but when I run it, nothing changes.

I can find out what the size currently is by typing:
float size = Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.SizeInPoints;
and that will bring up a size of 8. I do not know how to then set the size to something I want.

I've tried:
Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.Size.Equals(50);
which does nothing, and I've also tried

Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.SizeInPoints = 10;
which gives me an error of "Property or indexer 'System.Drawing.Font.SizeInPoints' cannot be assigned to -- it is read only"

So does anyone know what I can type to set the axis? Thanks for your help!

Hi,

in .NET some properties are read-only, i.e. you can get them but not set them.
Most often then there also is a "bigger" property that can be set.

Example: Form.Width is not settable, Form.Size is settable.

In your particular case you have to set a new TitleFont.

That makes sense, but I'm not sure how to do that b/c TitleFont is not a type. Could you give me an example?

Sorry no, I never used MSChart. Anyway, isn't TitleFont holding a Font instance?

Its got a FontFamily, but once again, its a get property, does not have any set properties. I'll see if I can tinker with it some more and figure it out. Thank for your help!

Hi,

I need to know when SetForegroundWindow return false because i try to set a form to the front using this code :

form.TopMost = true;
     form.BringToFront();
     bool focused = SetForegroundWindow(form.Handle);
     if (!focused)
         SwitchToThisWindow(form.Handle, true);
     form.TopMost = false;

the form is showen but without having the focus.

best regards.

Keep it simple, stupid!

IIRC, SetForegroundWindow returns false if the window is not brought to the foreground. In your case, perhaps it's because your form is already at the foreground.

If only there would be some official documentation that holds such trivial information.
Googling for it would have taken half the keystrokes and less than 1 minute.

You can also prevent other applications from stealing the focus, using TweakUI Smile | :)

<rant>
It's bloody annoying; you're typing merrily away, and suddenly start hearing the bleeping-sound of the computer-speaker because some programmer assumed that his application is important enough to disturb me during my work.

"Updates are available? Do you want to install/download them now?"

If you must steal focus, then steal the entire screen and blink it red. It's either really important, or you behave and don't bug me at all.

Some automation jobs may require SetForegroundWindow in order to use keyboard/mouse actions on another app. Of course this would require:
1. A user requesting it
2. A warning window telling the user he shouldn't touch anything until told otherwise.
3. The automation stuff
4. A notification to the user all is over.

/*\

assm = System.AppDomain.CreateDomain ( name ).

How does "Filename" look just before executing the ReadAllBytes when you put a watch on it?

Basically, the Assembly has to be in the same directory as the executing application.
Apparently you can load an Assembly from a different directory, but you have to set the AppDomains (both the current one and the new one) up properly to do that and I haven't bothered to do that.

string bin1 = "01100011";
string bin2 = "01101000";
int int1 = Convert.ToInt32(bin1, 2);
int int2 = Convert.ToInt32(bin2, 2);
byte result = (byte)(int1 & int2);
string binaryResult = Convert.ToString(result, 2).PadLeft(8, '0');
