Use this
Icon treeIcon = new Icon(Path + "Images\\History.ico");
DataGridViewImageColumn iconColumn = new DataGridViewImageColumn();
iconColumn.Image = treeIcon.ToBitmap();
iconColumn.Name = "ColHistory";
iconColumn.HeaderText = "History";
DataGridView1.Columns.Insert(12, iconColumn);
//Where 12 is location of column number

Do you mean a Console Project?

|
|
|
Helloooooooooooooooooooo
Yes i mean a console app.

Hi
In the properties of your project there's an option called "output type" (or something like that..) set it to console application and it will open in a console window.
|
|
|
|
|
If u are using IDE to develop application then, while selecting a new project you can choose the project type. Select a console project type.

Hi I've created a Custom Control "YoLabel" with
<br />
SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.ResizeRedraw | ControlStyles.SupportsTransparentBackColor, true);<br />
and drawing it inside OnPaint(...) method. The Control draws itself fine.
Now I need to paint something more from outside the label such as
<br />
YoLabel lbl = new YoLabel();<br />
lbl.Paint += delegate(object s, PaintEventArgs)<br />
{<br />
};<br />
Now the above Event Handler is not firing. Inside YoLabel Control I'm using invalidate whenever Text, Color, etc properties are changed to repaint it.
So what is missing. Please Advice.
Thanks...

do you call base.OnPaint in your override of OnPaint? the Paint - Event is fired from there.
|
|

Thanks m@u it worked fine...

Hi,

it seems like you have two YoLabels now, one got added to Form.Controls and paints fine
thru OnPaint, the second one is not part of any Control collection, hence will never
become visible or get its Paint event fired.
You should not create a second YoLabel, you should add your painting delegate to the
Paint event of the existing YoLabel.

Thanks for the interest codeproject. I'm creating a YoLabel as
<br />
MyForm : Form<br />
{<br />
MyForm()<br />
{<br />
YoLabel lbl = new YoLabel();<br />
lbl.Paint += delegate(...);<br />
lbl.MouseUp += delegate(...)<br />
<br />
this.Controls.Add(lbl);<br />
this.lbl.BringToFront();
}<br />
}<br />
So I have only one YoLabel...

then all is fine, as long as you call base.OnPaint() as the other reply mentioned.
some people by mistake create a new instance to invoke a method or add a delegate,
which obviously does not produce the result they are after.

AFAIK, you will need to specify the encoding in the HTML that you would load in the WebBrowser.

I have an application where configurations are stored in a XML file. I have a ConfigurationManager class which provides properties to all these XML data. I am looking for an efficient method to read data from the XML. I have tried the following
1 - Tried using XMLDocument class
Time taken : 20Milli seconds
2 - Tried using XML serializer
Time taken : 400Milli seconds
Obviously I could go with XMLDocument class approach. But I just want to make sure I am choosing the right method. BTW, is there any way to cache the configuration manager instance, then I can avoid reading it all the time.
