Change your last writeline to:
Console.WriteLine("{0} = {1}", tmpproperties[tmppi], tmpproperties[tmppi].GetValue(O));

Hi,
I was experimenting on the printing functions and found out you can get a lot of information about a printer trough System.Drawing.Printing.PrinterSettings. But I'm missing the minimum margins where the printer can print.
Most printers can't print to the edges of a page. These margins varies for eacht printer. Where can we find this information?
thx.

Check out the Margins[^] class.

thx for the reply...
But the Margins class allow to set margins, but it doesn't get the minimum margins of a printer. What I need is really the margin where a printer can't print.
For example a HP OfficeJet d155 minimum margins are
Left: 0,34 cm
Right: 0,93 cm
Top: 0,00 cm
Bottom: 0,67 cm
How can we get this information in .NET?
thx

I’m using the MS DataGrid on a form. Each row displays the state of an
instance of a class. When I load this form it creates the collection of
these classes and spawns a maintenance thread that keeps these instances
updated with info scraped from a website. Each class instance has a
reference to the DataTable of the DataGrid and is able to update its own row
in the grid. This works fine. You can sit back and watch this grid
refreshing "in the background" while manipulating other elements of the form.
I ran into problems when I tried to have this thread delete a row from the
grid. Intuitively this makes sense since there is probably a race condition
between the form thread and the maintenance thread where the delete is taking
place. I got around this problem by having the actual grid row deleted on the form thread.
But I'm worried that there might be some hidden race
condition waiting to happen when I do my updates. Any comments would be
greatly appreciated.
Thanks,
Kevin
Here is the error I get when I delete from the Update thread.

For pixel access in C#, which method is faster , using unsafe mode to access and manipulate pixels or writing wrapper and calling Win32 API GDI functions???
In broader terms, which technique is faster, unsafe mode or calling native Win32 APIs?
Thanks

Unsafe mode (LockBits). You're getting direct access to the bit data via pointers, which is pretty much as fast as you can get.

Fixed! Those 3 pages don't even exist anymore, so I removed the links.

Yes, I know... that needs to be done. My problem is that the background of the image was white before I added transparency, so the antialiasing that was done was lighter than everything else, instead of darker. I'll fix that.

Haha, it's pretty bad when the UI on the website for a UI toolkit is crappy. Makes you wonder... (Just kidding...I'm sure FLUID will be great )

That really is a concern though. I've waited far too long to do some changes that I had noticed earlier, because I was focusing on the project itself and the functional aspects of the site (which aren't complete yet). Since two of my main team members are away at present, I think I'm going to be working on improving the site this week.

Take a look at it now. I still need to fix the edges of the big logo, and I'm also going to make the chevron look nicer. The one I have is a bit strange.

I see you can set the focus to a control with controlname.focus for a Window form, but I don't see how you can do this for a webform. Anyone have any ideas?
Thanks,

IIRC you have to use client-side Javascript, which you can generate on-the-fly if necessary.

Hi,
I like to bind a collection to a listview-control.
So the listview-control must behave like a datagrid.
Is there somebody who has some code (C#) to do that or to extends the listview-control?
Thanks,
