Doesn't work, unfortunately:
public static T1 GenericMethod<T1>(IComparable<T1> value1, IComparable<T1> value2) where T1 : struct
{
if (value1 > value2)
{
return value1;
}
return value2;
}
is producing this error:
Operator '>' cannot be applied to operands of type 'System.IComparable<T1>' and 'System.IComparable<T1>'
It doesn't help to use "where T1: struct, IComparable" neither.

Yes, don't use the greater-than or less-than operator to compare the values, since not all IComparable objects implement those operator methods (seems silly they don't, IMO). Instead, use this:
if(value1.CompareTo(value2) > 0)
{
return value1;
}
return value2;

Thanks for the hint!
The final compilable notation would be this:
public static T1 GenericMethod<T1>(IComparable<T1> value1, IComparable<T1> value2) where T1 : struct
{
if (value1.CompareTo((T1)value2) > 0)
{
return (T1)value1;
}
return (T1)value2;
}

I am working with large bitmap files. In general centering on the mouse click does not cause any problems. If I am zoomed out(max 1/4 of original size) and then zoom in (max double original size) quickly and try to center on the mouse click I get an InvaidOperationException unhandled BufferedGraphicsContext cannot be disposed of because a buffer operation is currently in progress.
I have looked at BufferedGraphicsContext and tried setstyle with AllPaintingInWmPaint, OptimizedDoubleBuffer, UserPaint set to true but still get the same error. Could anyone point me the direction I need to go to correct this problem or what kind of try/catch I need to implement?
Thanks Jim

public delegate int TestDelegate(int c,int d);
A delegate can reference a method only if the signature of the method exactly matches the signature specified by the delegate type.
Mainly a delegate needs a signature.i.e..return type and input parameter datatype.
Why i need to say the variable name with the datatype "int C & int D". Is MS is using this "int c & int D" internally.

I agree, technically there is no need for variable names here; but C# expects them,
and you can benefit in readability, especially if you also add /// comments for
Intellisense.

What do you mean by "voice application"? TTS? Recognition? Both?
You might find this[^] to be a useful read. And this CP article[^] and this[^] should help you get started with TTS.

When a tree node is pressed with a right click it highlights it and then selects back the node that was selected before, how can i make the node be selected on right click as well?
|
|
|
|

In the NodeMouseClick event:
treeview.SelectedNode = treeview.GetNodeAt(e.Location);
|
|

Worked like a charm :P
Thanks alot

Use a DataGridView and set the DataGridViewColumn.Visible property to false for the particular columns in the Columns collection.

Hi
I have created a control the is transparent. When this is placed a normal form with a picture it works fine, but when it is on a control container where I draw the background as a gradient using the drawing tool, the transparency only shows the background colour of the control, and doesnt work over the image/gradient that i've drawn.
How do I get the background to draw first, or how do I get the control to look at what is painted on its container.
Thanks in advance

In visual studio 2005 within an asp.net project you can bring up the style builder by placing an html input control on a web page and going to style in the property grid. I would like to use this editor in a windows C# project on my property grid.
How do I make the following show that editor in my class that is the "SelectedObject" in the property grid?
class mySelectedObject
{
private string mStyle;
/// [I know I need to put something here in the brackets]
public string Style
{
get { return mStyle; }
set { mStyle = value; }
}
}
Thanks

Tried it and it doesn't work....

Hmm. The property type is string, so the property grid should just show an area where you can enter a string. But if you want to specify a specific editor, look up [EditorAttribute]. Hope that helps!

using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web.UI.WebControls;
using System.Web.UI.Design.WebControls;
namespace Test
{
class LabelProperties

using System.Web.UI.Design.WebControls;
namespace QWareAdvantage.Controls
{
class LabelProperties
{
private Style mName;
[Browsable(true)]
[Editor(typeof(StyleCollectionEditor), typeof(System.Drawing.Design.UITypeEditor))]
public Style Name
{
get { return mName; }
set { mName = value; }
}
}
}
