Hi Guys.
Any ideas on how to find out the ColorSpace of an image file. It doesn't seem to be available through the normal properties/attributes.
Image might be a tif, jpg, bmp, etc.
The app needs to move cmyk pics to one directory while rgb pics go to another.
Any help for a newbie would be appreciated.

I would like to write some software which checks the status of a printer, gets number of page counts, error details, paper capacity levels etc. through the network.
The printer I using is a DocuPrint N4525.
Some options could be MIBs, LPR/LPD, Port 9100, port 80, IPP, SNMP.
What would the best way be and where could i find documentation for that.

Your going to have to get with Xerox on that. They have their own program that retrieves that kind of information from the printer. And since you have to register that program, I'd guess that they are not going to give up the protocol information without a fight.
I can't find any publicly available documentation on how these stats are retrieved. I can tell you it is done using TCP Port 9100 on the printer, but the only documentation on that port is that it supports RAW printing, although the documentation on XManager states that it also uses that port for two way communication that does exactly what you want.

There is a .NET component what I at this site[^] that does that.....
|
|
|
|
|
That component monitors the queue and the jobs in it. It does not monitor the status of the printer itself. What he is looking for is hte status of the printer, the error logs, paper capacity remaining, ... stuff like that.
|
|
|
|
|
The PrinterMonitorComponent.PrinterInformationChanged will fire when the status of the printer changes and the PrinterInformation class passed in the event args has status, pages printed etc....

I'm sorry, but I don't see in your components, where it returns the printer's Error History and current Paper Capacity remaining.

A colleague of mine is using the Shell command to run winzip and compress the files, with the 'Wait' parameter set to True, but sometimes when subsequent code tries to move the zip file, an exception occurs because the file is reported to be in use.
I suspect that winzip is somehow slow at releasing the file, and Shell returns before this happens. Any ideas?

I would like to be able to pick a colour on a PictureBox control and make it transparent. How can I then save the image as a gif file with transparency. I have a program that draws shapes on an image in a picturebox, however when I save the image none of the shapes that I have drawn are saved. What do I need to do to achieve this. Any help is appreciated.

OK, first of all, are you drawing the shapes on the PictureBox's Graphics, or a Graphics created from the bitmap? You need to create a graphics from the bitmap using Graphics.FromImage(), and then draw on that.
About transparency, I really don't know how to do that with GIFs in GDI+. I believe the first entry in the palette is the transparent color, but I don't know how to set that with GDI+.

Thanks for your reply
In my program the PictureBox is either loaded from a file:
pictureBox.Image = Image.FromFile(dlg.FileName)
Or from a stream:
Dim binaryData(-1) As [Byte]
binaryData = Base64Utility.GetByteArray(_ImageData)
Dim ms As New MemoryStream(binaryData)
_PictureBox.Image = Image.FromStream(ms)
To draw on the PictureBox I am calling the Invalidate method which then fires the Paint event:
pictureBox.Invalidate()
In the paint event I am passing the PaintEventArgs to this Draw Sub.
Public Sub Draw(ByVal p As Pen, ByVal e As PaintEventArgs) Implements IHotspot.Draw
If _bEndIsSet Then
e.Graphics.DrawRectangle(p, New Rectangle(_ptOrigin.X, _ptOrigin.Y, (_ptEnd.X - _ptOrigin.X), (_ptEnd.Y - _ptOrigin.Y)))
e.Graphics.DrawRectangle(p, _ptEnd.X - 2, _ptEnd.Y - 2, 4, 4)
'e.Graphics.DrawString(CStr(_ptOrigin.X) & ":" & CStr(_ptOrigin.Y), New Font("arial", 8, FontStyle.Regular), Brushes.Yellow, _ptOrigin.X, _ptOrigin.Y)
End If
End Sub
So instead of using e.Graphics I should be using Graphics.FromImage() to draw on?

Correct. In VB6, you could draw on the picturebox and what you drew would show up on the image, but with VB.NET, this doesn't happen. IMO it's much better that way.

Sorry, but that struck me as very tongue-in-cheek.

I won't say it is a problem. Just that I was interested to know wheither VB.NET has a MDI template like in MFC MDI?
I have checked out VB.NET. It seems that most the stuff need to be built on scratch.
Any hints? Thanks

Create a (parent) form and set the form's IsMdiContainer property.
- <parent>.IsMdiContainer = True
Create a child form and set the child's MdiParent property to point to the parent form.
