Paint.NET comes with source code. You can see how they manipulate images.

This is trivial. Just draw the picture yourself, and use a scale transform on the Graphics object, change the scale according to whatever UI you want to control zoom.

I am capturing a file from a folder and displaying it.
How would I go about changing the scale as you suggestion as by now you will realise I have not got a clue. New to this.

Thanks Dave for the following, it works a treat and yes easy
*******
Easy. Drop the PictureBox control into a Panel control on your form and set the Panel's AutoScroll property to True. In your code, load the image you want into an Image object, then set the PictureBox's Image property to that Image object and set the Size of the PictureBox to the size of the Image or to any size to you want.
*****
My next problem was when I put the image (tiff) into the picture box it is huge, have to use the scrolls bars. It there any way I can make the image a wee bit smaller when loading to save me making the object take up the whole screen. With crystal reports you have a command like
CrystalReportViewer1.Zoom(1)
Also I use XP and just found out it does not work with Kodak Image Edit Control. Works great with Win 2000. Is there anything out there, free, that does the same as Kodak but with XP
Does this make sense?

You can set a picture box to show the entire image stretched to fit whatever size the picture box is.

The problem I am having is, what if it is a large image by fitting onto the picture box size it becomes unreadable.
I must be doing something wrong with incoming file.
|
|
|
|

By unreadable, do you mean hard to understand ? If you shrink an image by a large amount, it's obviously going to lose all detail.

True, but how can I shrink the image to such a size that it is readable. Then after that use the scroll bars to view different areas if needed.
Am I making sense?

You can tell the picturebox to shrink the image. If you want to use scrollbars instead, then you need to handle the drawing yourself, the picturebox becomes useless in this case.

Hi,
My application (designed in VB.Net 2.0) works good on local computer but when I deploy on server and try to run from clients I get following error:
'system.data.sqlclient.sqlclientpermission, systemdata Version = 1.0...,culture=neutral publickeytoken = ..... failed'
I have to run this appplication from 100s client computer and can't install on each client.
I have changed permissionSeting on server by using Microsoft .NET Framework Configuration Console and allowed 'FullTrust' for Local_Intranet_Zone, but still having the same error.
Can anyone help me out for this problem.
Regards

Have you tried something like:
CasPol.exe -m -ag 1.2 -url file://Server/MyShare/* FullTrust

I have a problem concerning a row selection in a datagridview.
If i click on any cell in a specific row in a datagridview, I need it not to do anything, not even change the old selection in another row. I could not find any cancel for the click event on a cell. Do anyone have any solution for my problem?
Datagridview Selection
|
|
|
|
|
Have you tried SelectedIndexChanging, and set e.Cancel = true; ?
|
|
|
|
|
There is no SelectedIndexChanging in the datagridview events.

I want to trap system mouseup and mousedown events whether they are on any application .
Thanks in advance
Thanks
|

I believe you have to look into windows hooks. Install a hook into the OS and handle the wndproc looking for the events as they appear. I have no idea how to do it, but you might be able to narrow you searching.

Sorry if this is elsewhere but I look and could not find.
Can I / How do I create an arrarylist of an object.
For instance for the below object
Public Class Posts
Public Name As String
Public ID As Integer
Public Selected As Boolean
End Class
Cheers
Geoff

Add a method that creates the ArrayList:
Public Class Posts
Public Name As String
Public ID As Integer
Public Selected As Boolean
Public Function MakeList() as ArrayList
Dim list as New ArrayList();
list.Add(Name);
list.Add(ID);
list.Add(Selected);
Return list;
End Function
End Class
I don't really know if this is the solution you want, as you haven't told anything about what you are trying to accomplish. If it's not, you have to surrender a bit more information...
