either use a MaskedTextbox or use a regular TextBox and let the KeyPress handler reject
all characters you don't want (you probably should allow all char.IsControl so BACKSPACE
and CTRL/C and CTRL/V remain operational).
All the details (as well as the above) can be found in the documentation; and Google is a
nice way of locating it.

Create a Uri object with your stored string. Then access the Host property.
Example:
Uri url = new Uri("http://www.codeproject.com");<br />
string domainName = url.Host;

Is it possible to make the soapformatter ignore missing fields?
Eg if the file have been saved in a previous format and I later try to deserialize it into a new format where not all fields match 100%
Im aware of [OptionalField], but that is the opposite of what I want.
Optional lets me introduce new fields into my format.
I want to simply ignore old fields that are not used any more.
And I also know that I can implement ISerializable, but I do not want that, I just want to use the default mechanism but ignoring missing fields.
(last resort would be to roll my own formatter, but im trying to avoid that)

Hello all,
Does anybody knows how to change the default caption text in the ColorDialog component of .Net 2.0? Default it is set to "Color", while I want to be able to change this into: "Select foreground color".
With regards,

Hi. I need to take a screen shot of a control - the control is plotterForm.expressionPlotter. I am using the following code:
<br />
private Bitmap GetBitmap()<br />
{<br />
Bitmap bmp = new Bitmap(plotterForm.expressionPlotter.Width, plotterForm.expressionPlotter.Height);<br />
Graphics g = Graphics.FromImage(bmp);<br />
Screen screen = Screen.FromControl(plotterForm.expressionPlotter);<br />
g.CopyFromScreen(new Point(screen.Bounds.Location.X, screen.Bounds.Location.Y), Point.Empty, plotterForm.expressionPlotter.Size);<br />
return bmp;<br />
}
The problem is that the location of which the screen shot is always the upper left corner of the desktop, not the upper left corner of the control.
In other words the screen.Bounds.Location is a point which is always (0;0). When i added MessageBox.Show(screen.ToString()); i received the following message:
Screen[Bounds={X=0,Y=0,Width=1024,Height=768} WorkingArea={X=0,Y=0,Width=1024,Height=739} Primary=True DeviceName=\\.\DISPLAY1
As if the screen hasn't captured the control. How can i fix this???

I realized that the Screen.FromControl is something entirely different from the thing i expected! But here comes another question - how can i find the location of a control in relation to the desktop?

|
Use...
PointToScreen(control.Location);

Can you not just use DrawToBitmap as in:
int height = plotterForm.expressionPlotter.Height;
int width = plotterForm.expressionPlotter.Width;
Bitmap bmp = new Bitmap(width, height);
plotterForm.expressionPlotter.DrawToBitmap(bmp, new Rectangle(0,0,width,height));
Because if you could i imagine it will be much easier.

I changed the code of the project a little bit and the control which i want to capture is a panel. The panel has a written text using the DrawString method of the Graphics class.The screen shot is stored in the clipboard. When i take a screen shot using DrawToBitmap , when i paste the image in paint it appears, but the text isn't there.
The taken screen shot[^]
The image as it should be[^]
Why doesn't the DrawToBitmap method capture the text???

i don't know, i had trouble with a textbox not drawing the text when i used DrawToBitmap. Then all of a sudden it just started working. and i'm not sure why/

Take a screen shot of the whole screen and then use an image editor?
Or, what I did was write a simple applet that I can position over the section of the screen I want to capture and have do the capture.

Im 99% sure that the DrawToBitmap method will invoke the OnPaint method on the control and pass a graphics object containing the bitmap.
so if you draw the text outside of the OnPaint method, that code will not be triggered when calling DrawToBitmap.
How are you drawing the text?
Control.CreateGraphics?
|
|
|
|

This is how things are:
I have created a control - ExpressionPlotter. It is used to plot math graphs - they are drawn on the control. The control has a panel which contains the graphs' information. In the OnPaint method of the ExpressionPlotter is the method which draws the text - DisplayExpressionsText. In DisplayExpressionsText the panel is sized according to the text and then in the drawing of the text the method panel.CreateGraphics is used to obtain the Graphics class. When it comes to the screen shot the DrawToBitmap is called for the ExpressionPlotter control.
I tried to draw the text in the Paint event of the panel, but when i started the program, the panel didn't show.
Still learning...

I did it! I moved the resizing of the panel to the OnPaint. Then i moved the drawing of the text to the Paint event of the panel. When i want to draw the text now i only have to Refresh() the panel.

That's your problem. That means that you are always drawing the text on the screen. Use the Graphics object that is supplied in the event arguments to the Paint event.
Despite everything, the person most likely to be fooling you next is yourself.

Take a look at my article clickety in which I cover basic screen capture as well as capturing a specific area of the screen.
The source code is available for download from the article as well.

Thank you for sharing the exception. Is there some code that goes with it?

Hi,
I don't see any Invoke() or BeginInvoke(), and I don't see a button click handler either.
if you want effective help, show the relevant code, and use PRE tags. Read my sig.
