You need to override the OnMouseDown event and check the parameter
if(e.Button == MouseButtons.Right)
object obj = this.shapesListView.GetChildAtPoint(e.Location);
...
Check out the following article for details.

Good day Guys,
Please help! I'm in a dire situation right now. I have a program which works much like a cash register. I have a set of command buttons in one form in which I want to change the properties (e.g., text/caption, font size, backcolor, etc...) based on what is stored from the database. The thing is, I don't know how can that be specified! Please help!

Ok I am in a dilema here. I am working on a BI module. I am reading the data from a tabl using a Sql's "With Cube" function, my result set looks like following:
+---------+-------------+----------------+
|#ofReqs--|---SDate----|Department------|
+---------+-------------+----------------+
|--------3|3/10/2006----|--Hardware-----|
+---------+-------------+----------------+
|--------2|3/12/2006----|--Hardware-----|
+---------+-------------+----------------+
|--------5|3/15/2006----|--Hardware-----|
+---------+-------------+----------------+
|--------4|3/17/2006----|--Hardware-----|
+---------+-------------+----------------+
|--------9|3/10/2006----|--SoftWare-----|
+---------+-------------+----------------+
|--------8|3/12/2006----|--SoftWare-----|
+---------+-------------+----------------+
|--------5|3/14/2006----|--SoftWare-----|
+---------+-------------+----------------+
|--------9|3/15/2006----|--SoftWare-----|
------------------------------------------
What I need is a collection of Reqs; a collection of Date; a Collection of Department but I need them to be related with each other cuz I need to use them on a graph.
What I am trying to display on the graph is as follows:
Day wise No of Reqs made to a Department.
something like NameValueCollection<string, string=""> so if a string key [Department] is repeted the result would get added to it another element does not get created; but with three values NameValueCollection<string, string,="" double="">
Whatever.Add("Software", "3/14/2006", 5);
//result Software [Key] - 3/14/2006, 5 [Value]
Whatever.Add("Hardware", "3/14/2006" 3);
//reult Hardware[Key] - 3/14/2006, 5 [Value]
Whatever.Add("Software" - 3/10/2006, 4);
//result Software [Key] - [3/14/2006, 5] [3/10/2006,4] [Value]
Something like... I dont know, I hope I am not over complecating the problem. Does any one have a clue what I am talking about

I thought about that
Lets say I create a dataset. How am I going to get the result set that I want? Can I query against the DataSet?
Would you be able to give me an example please? Thanks for the help.

Hi!
I have a little code to resize and watermark images. The problem is that it generates images with really poor quality. I have a comparison below with my results with code and PhotoShop, what I want is to make the code generate a copy with the same quality as PhotoShop, if it's possible. You just have to tell me what to add and where! Please!
These images are automatically resized from a much bigger image found at:
http://www.foh.nu/heli.jpg[^]
Generated with code: http://www.foh.nu/heli1.jpg[^]
Generated with PhotoShop: http://www.foh.nu/heli2.jpg[^]
Don't change too much in the code, I still have to remain the canvas and image as is, becouse I have to draw more images into the canvas later on, for protection (copyright image, transparent, etc.)
This is the code at the moment:
<br />
void makeThumbnail()<br />
{<br />
System.Drawing.Image image = System.Drawing.Image.FromFile("C:\\Inetpub\\wwwroot\\heli.jpg");<br />
Bitmap canvas = new Bitmap(200, 283, image.PixelFormat);<br />
<br />
Graphics g = Graphics.FromImage(canvas);<br />
<br />
g.DrawImage(image, 0, 0, 200, 283);<br />
<br />
canvas.Save("C:\\Inetpub\\wwwroot\\1.jpg", ImageFormat.Jpeg);<br />
<br />
image.Dispose();<br />
canvas.Dispose();<br />
}<br />
Hope you can help! Cheers!

try adding
g.InterpolationMode = InterpolationMaode.HighQualityBicubic;

Hi
You can use a quality parameter when saving as a jpeg:
...
int quality = 90;
EncoderParameters parameters = new EncoderParameters( 1 );
parameters.Param[ 0 ] = new EncoderParameter( Encoder.Quality, quality );
ImageCodecInfo codec = GetImageCodecInfo( ImageFormat.Jpeg );
canvas.Save("C:\\Inetpub\\wwwroot\\1.jpg", codec, parameters );
...
public static ImageCodecInfo GetImageCodecInfo( ImageFormat format )
{
ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
foreach ( ImageCodecInfo codec in codecs )
if ( codec.FormatID == format.Guid )
return codec;
return null;
}

public static ImageCodecInfo GetImageCodecInfo(ImageFormat format)<br />
{<br />
ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();<br />
foreach(ImageCodecInfo codec in codecs)<br />
{<br />
if(codec.FormatID == format.Guid)<br />
{<br />
return codec;<br />
return null;<br />
}<br />
}<br />
}<br />
<br />
void makeThumbnail()<br />
{<br />
System.Drawing.Image image = System.Drawing.Image.FromFile("C:\\Inetpub\\wwwroot\\heli.jpg");<br />
Bitmap canvas = new Bitmap(200, 283, image.PixelFormat);<br />
<br />
Graphics g = Graphics.FromImage(canvas);<br />
<br />
g.DrawImage(image, 0, 0, 200, 283);<br />
<br />
int quality = 90;<br />
EncoderParameters parameters = new EncoderParameters(1);<br />
parameters.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality);<br />
<br />
ImageCodecInfo codec = GetImageCodecInfo(ImageFormat.Jpeg);<br />
canvas.Save("C:\\Inetpub\\wwwroot\\1.jpg", codec, parameters);<br />
<br />
image.Dispose();<br />
canvas.Dispose();<br />
}<br />
<br />
Gives the following error:
Compiler Error Message: CS0161: 'ASP.image_aspx.GetImageCodecInfo(System.Drawing.Imaging.ImageFormat)': not all code paths return a value
On line:
<br />
public static ImageCodecInfo GetImageCodecInfo(ImageFormat format)<br />

You can try setting the quality to 100%.
If that still is not good enough, then you could try saving in a loseless format such as png ( then you don't need the quality parameter ).

Not a bad idea actually ..

Actually that doesn't solve a thing. It still makes it crappy quality. It's not the loss that's the problem, it's the antialiasing .. it doesn't do it when I resize the image.
Still get the same result. :-/

Have you tried using Image.GetThumbnailImage ?
I'm running out of ideas here

I don't know how to use it but I'll figure it out!
Thank you for the input. I'll get back on the thread when I've got the time to investigate it more =)

I have a .NET C# application that connects to databases and creates tables and such and works on MSSqlServer and an Oracle Server I've tested it on and now I would like to get it sorking on DB2 as well. I've noticed there aren't the same components for DB2 as there are for Oracle and Sql so I did some research and it seems the only good looking components come from IBM and/or cost $. I've tried using the code already in place with an OleDbConnection and Command and it works for creating the tables but I haven't gotten it to insert without throwing an error. I think the error is has to do with the parameter field of the command. I have tried it with @ before the column names as with SQL and : as with Oracle, but neither solution works. If anyone has any experience with similar problems I would appreciate any help.

IIRC OleDbCommand does not support named parameters. Use a ? character as a parameter placeholder, and add OleDbParameter s to the Parameters collection in the order that they appear in the query text.
Stability. What an interesting concept. -- Chris Maunder

I've tried this solution, and I think it makes sense for select statements, but for inserts the syntax doesn't look right and it doesn't work.
Ex:
Insert into table(col1, col2, col3), (?, ?, ?)
parameters:
@col1, value, type
@col2, value, type
@col3, value, type
I have tried this with @before the column names, :before them and nothing but the column names.
These statments have worked for me (with the column names instead of ?'s) in SQL and Oracle, so I have a hard time believing it can't be done in Db2.

It seems that if I use dataview in my app, and a change is made to the dataset, and I call Update(ds). It does not update the datasource.
Here is my code in the form_load section:
<br />
sqlDataAdapter1.Fill(dataSet11);<br />
<br />
SqlCommandBuilder cb = new SqlCommandBuilder(sqlDataAdapter1);<br />
<br />
dt = dataSet11.Tables[0];<br />
dataView1.Table = dt;<br />
<br />
cm = (CurrencyManager)this.BindingContext[dataView1];<br />
<br />
cm.CurrentChanged += new System.EventHandler(OnCurrentChanged);<br />
lblRecord.Text = "Record " + (cm.Position + 1) + " of " + cm.Count;<br />
and the code in my save record section:
<br />
if (dataSet11.HasChanges())<br />
{<br />
cm.EndCurrentEdit();<br />
<br />
sqlDataAdapter1.Update(dataSet11);<br />
}<br />
<br />
I'm not sure why it does not update. If I remove the dataview then it updates the datasource. Suggestions?
Thanks
