Hello,

I have an instance of System.Drawing.Bitmap that I whant to send to a defined Printer.
No idea how to do that. Sigh | :sigh:

If its only possible over a file, I would use the Bitmap.Save() Method to save it somewhere temp.
But I would prevere a solution without saving to a file.

I get the printers out of the System.Drawing.Printing.PrinterSettings.InstalledPrinters.

I looked into namespace System.Drawing.Printing, too following classes:
PrinterSettings (Here I could set the printer name)
PrintDocument (There is a Print() Method)

But I have no idea how too tell the PrintDocument which file or better Bitmap, too print.

Best solution for me would be without DialogBoxes. (No interaction for the user)

I would really be thankfull for your help.

Martin

Hi,

you are principally working with the correct classes. If you have configured yor PrintDocument and PrinterSettings with all required settings than call Print() on the PrintDocument. It will raise a PrintPage event. You'll have to catch this. The event arguments provide a Graphics object where you can draw your bitmap into.

OOOOOOOOOh, D'Oh! | :doh:

I found such a solution somewhere, but didn't whant too believe that after the event was fired, I could change some data.

I will try it now and tell you what happens.

Thank you very much for helping so fast..

Thank you again Robert.

It works fine! Cool | :cool:

I used:
e.Graphics.DrawImage(Bitmap,0,0);
for the conversion.
Hope this is the recomended way to do it.

All the best,

Label.TextAlign problem

Hello...

It seems Label.TextAlign doesn't work anymore in VS2005.
I just put a label at the right side of my form and set TextAlign to MiddleRight. Then I just write something long, for example "ABCDEFGHIJKL...".
The label grows not to left, but to right. I try to set the size using property window, it doesn't work also. The size seems to be set automatically.

Has anybody any solution for this ?

Thanks...

Hi,

I think the different behaviour comes from the fact that in VS2005 the AutoSize property is by default set to true and not like in VS2003 to false.

Hi,

I assume you are using a DataGridViewImageColumn. It has a ImageLayout property where you can set the resizing behaviour.

Object refernce from its string name

I am trying to get a reference to an object by its name (string). Can we do this in C#. Please help.

Object objA = new object();

I wanna get reference to objA, by saying something like GetReference("objA")

You can do this with reflection. It's complicated, and expensive. Why do you want to do this ? Where is objA, that you have to go looking for it ?

If you explain what you are trying to do maybe we could help more.

You just move your window so the frame is outside the visible area. You can also set your frame type to not have one, if you prefer.

hi,
thanks for you reply but i am sorry, i couldn't understand what u are trying to tell me. if you please elaborate a little.

You just move your window so the frame is outside the visible area.

why should i move the window so that it is not visible. i need it to be full screen.

best regards

*sigh* The frame is all around the edges of your window. If the top of the frame is *above* the top of your window, the left frame is past the left edge of your window, etc, then your app will appear full screen, right ?

sorry man i am not understanding what u are trying to tell me. Confused | :confused:

Let us make it a simple question. Is there any code or instruction that makes the frame appear as a full screen application not a maximized application

thanks

Like I said in the first instance, you can set the app to not have a frame. That is a single line in .NET, but in MFC, we used to do what I've been trying to explain to you.

You can set FormBorderStyle to None.
