I've tried the code below, and various code frm a number of books, I'm using V1.1. I know there is a image on the clipboard because I can paste a copy to the same folder as where I copy/cut the image.
(I know the code looks weird, but I've tried bothversions with the other one commented out)
If anyone has any code that works I'd be gratefull, this might also be releated to a problem whereby I can drag a image from a folder to my PB, but not from IE or Mozilla.
I'm very new to C#, so help really is needed 
private void mnuPaste_Click(object sender, System.EventArgs e)
{
IDataObject d = Clipboard.GetDataObject();
if(d.GetDataPresent(typeof(Bitmap)))
{
Bitmap b = (Bitmap)d.GetData(typeof(Bitmap));
b.Save(@"m:\mybitmap.bmp");
MessageBox.Show("Bitmap saved to disk!!");
}
else
{
MessageBox.Show("No bitmap information was contained in the clipboard.");
}
// Create a new instance of the DataObject interface.
IDataObject data = Clipboard.GetDataObject();
// If the data is text, then set the text of the
// TextBox to the text in the Clipboard.
if (data.GetDataPresent(DataFormats.Bitmap))
{
//textBox1.Text = data.GetData(DataFormats.Text).ToString();
// Yes it is, so display it in a text box.
picCoverFront.Image = (Bitmap)data.GetData(DataFormats.Bitmap);
MessageBox.Show("paste") ;
}
}

trythat wrote:
(Bitmap)data.GetData(DataFormats.Bitmap);
This piece of code is important. A clipboard data object (also used in dragging and dropped) uses one or more clipboard formats. These are merely strings. .NET makes it easy by registering these clipboard formats for you. The important thing is that the strings match from source to target. When you copy a bitmap from most applications (including Windows Explorer, Office, etc.) - and even your application above (the lower part), you use the string value for DataFormats.Bitmap. In your target app (the upper code), you are using typeof(Bitmap), which yields an entirely different string! Instead, do:
if (d.GetDataPresent(DataFormats.Bitmap))
{
Bitmap bmp = (Bitmap)e.GetData(DataFormats.Bitmap);
}The string you use isn't so much important (unless you want to be compatible with common formats when copying/pasting with other applications) as it is that they match between your source and target applications.

Thanks for answering, but I still can't get it to work, I tried the above code and it always falls thru to the else statement, even though I'm trying to paste a jpg, all I really want to do is paste a image to my PB.
Do I need to have any code added anywhere else or SHOULD the above work?

I don't know off the top of my head, but copying a JPG file may not use the DataFormats.Bitmap clipboard format. The best thing I can tell you is to set a breakpoint at your condition and debug your app to see what formats are there. You can also use ClipSpy[^] to also see what formats are being used.
What exactly are you copying this file from? If you're doing it in your own program, make sure you copy the data into the DataObject the same way and using the same clipboard format as you do when you retrieve it.

Thanks again, downloaded Clipspy - I'll have a good read first 
I'm trying to copy mainly from other folders, I can now drag&drop from another folder, but not from another program - mainly IE. I only want to paste/drag&drop to my program, and the books make it look so easy  they all seem to be the same code I pasted in my first message - so I'm not sure what I'm doing wrong.

The only thing you seem to be doing wrong is using the wrote clipboard format. Be sure to copy a JPEG from Windows Explorer into the clipboard, then examine it with ClipSpy to see what formats are there. If DataFormats doesn't have the string you need represented, just pass the string itself - that's all that it is). If nothing else, read the sections of the Windows Shell documentation in the Platform SDK that deal with the clipboard, dragging and dropping, and clipboard formats. I did many many years ago and I'm glad I did.

Thanks Heath, I'll try that out and see what I can manage, I'm also going to have a quick gander at the Clipspy source to see if I pick some tips up from there as well.
Thanks again -

I'm currently writing a C# MIME parser and a problem has occured, encoding 
I've written a hack that converts iso-8859-1 to a readable form by taking out the ASCII-value of the characters and then replace the code (for example =E5 is the swedish character 'å') with the corrent character. But today I got a nasty spam with the following text (in the header) that I don't know how to encode:
From: =?koi8-r?B?6OhMLfRB6EkgKDk5NS04Mjk0KQ==?= <mc7yfccu@buch.de>
The charset is koi8-r, but then? According to another email-client the correct translation is èèL-ôAèI (995-8294) <mc7yfccu@buch.de>
Is there a general way of converting strings with known encoding-strings like koi8-r, iso-8859-1 etc?

Take a look at Encoding.Convert (and the various encoding-related classes). This converts to/from ASCII, UTF7, UTF8, and Unicode, so any charsets should be able to convert.

Hi,
This encoding is called as Canonical encoding.
Format: =?charSet?type[Q or B]?encoded string?=
Q - quoted-printable encoding
B - base64 encoding
You can see my developed mime parser, it hanles all this stuff.

I have to write an application that has to track all applications that have been opened. Basically I have to record when an application was launched, from where (which file) it was launced. I have no idea where to begin. Any ideas?
Thanks

It's easy to get a list of the processes that are running, and when the started and finished, .. mmm.. take a look to
System.Diagnostics.Process
Some time ago I make an small tool that just pooled for something like that.

Hi,
I'm just new to C#.net I just want to know how to create a global database connection, so that I will only use one connection in my application in all my forms. Hope I can find the answer... Thanks...

Hi,
you could create an static class, and have a method called "getConnection" from there you can get the connection from anywhere.
Just one advice... I would use connection less, instead of single connection, ... just connect to the database when you need it, the .net Framework keeps a pool of connections so no loose of performance when reopening the connection

akokini,
There's a difference between defining the connection globally, vs. having a global connection. Defining the connection globally is good practice, and can be done either through the .config file, or through a static variable. Having a global connection is VERY bad, since it will destroy your ability to have proper connection pooling, and even worse, could cause serious problems between different classes if they're all using the same connection at the same time.
Here's an example of defining the connection through a static variable:
using System;
using System.Configuration;
namespace sean.config
{
public class Config
{
public static string DataBaseConnection = @"server=192.168.0.1;Trusted_Connection=false;uid=sa;pwd=;database=Northwind"}
}
You could then reference it anywhere in your code by doing the following:
SqlConnection conn = new SqlConnection(Config.DataBaseConnection)
You could take it a step further, and define the connection in a config file. Here's an example:
The configuration file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="mydb" value="server=192.168.0.1;Trusted_Connection=false;uid=sa;pwd=;database=Northwind" />
</appSettings>
</configuration>
The modified config class:
using System;
using System.Configuration;
namespace sean.config
{
public class Config
{
public static string DataBaseConnection = @ConfigurationSettings.AppSettings["mydb"];
}
I hope that helps!

Hi,
Can anyone tell me how can i create database query for an excel workbook with c#?
Thanks.

I think you can access an Excel file just using ADO .net, take a look at the net for samples. Good luck
