The combobox has a MouseWheel event but it appears to have no way of altering the data (the properties are all read only) or cancelling.
You may have to invesigate in the API: WM_MOUSEWHEEL[^]

This works!
namespace WindowsFormsApplication1
{
public partial class Form1 : Form, IMessageFilter
{
private const int WM_MOUSEWHEEL = 0x20A;
public bool PreFilterMessage(ref Message m)
{
if (m.Msg == WM_MOUSEWHEEL && this.ActiveControl == comboBox1)
{
return true;
}
return false;
}
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Application.AddMessageFilter(this);
}
}
}

I hope you know how to use Google, since that's how you will find what you need[^] I guess.

Hi,
C# vs2005. Im creating a simple web page image upload program.
The user enters a local directory and the web page displays thumbnails of all the images in that directory.
This works fine if I create thumbnail files on the server and display the images using their virtual paths eg "/images/image1.jpg"
Copying the files can be time consuming so im trying to get the same result without creating my own thumbnail copies.
I create ImageButtons and set the image url to be the absolute location of the image on the client eg "c:\temp\images\image1.jpg"
When I run the app the images are not displayed. If I copy the generated html and load it in another instance of internet explorer the images are displayed fine.
How can I get images to be displayed using absolute paths when the images reside on the client?
Many thanks,
Chas

I have created an invoice like crystal reported,
Which gets it data from a stored procedure with 1 parameter which tells which invoice data to use.
Now the problem is that it always tryes to execute this stored procedure from the server it was created on, I have set the database login but it still doesnt execute from that database.
Now im either looking for a method of fixing this or another method to get the data in.
I have tryed using a dataset using the SetDataSource function but i have no idea how i can assign or even get the fields in the crystal report designer mode to there proper locations.
Thanks
ReportDocument Report = new ReportDocument();<br />
if (File.Exists("factuur.rpt"))<br />
{<br />
Report.Load("factuur.rpt", OpenReportMethod.OpenReportByTempCopy);<br />
}<br />
else if (File.Exists("..\\..\\factuur.rpt"))<br />
{<br />
Report.Load("..\\..\\factuur.rpt", OpenReportMethod.OpenReportByTempCopy);<br />
}<br />
else<br />
{<br />
MessageBox.Show("Factuur.rpt niet gevonden, opdracht kan niet uitgevoert worden");<br />
return;<br />
}<br />
Report.SetDatabaseLogon(settings.user, settings.password, settings.server, settings.db);<br />
Report.SetParameterValue("@FactuurID", ID);<br />
crystalReportViewer1.ReportSource = Report;<br />
<br />

Strange but give this a try -
Within crystal reports, ensure file/ report options/ 'save data with report' is unselected.
Ensure settings.server value is the correct one you want.
In the Report.Load try only sending the filename.
Failing that I would just open the report in crystal reports and under database - set datasource location use the final database you want.
Thanks,
Chas

(32 KB)
i can change the Toolbox icon for new components but when i dragged it into form i have got the default icon . how to solve it !!
Thanks in ADvance

How are you setting the toolbox icon? Using the ToolboxBitmapAttribute, it sets the icon in the toolbox and in the form's component area.
Take care,
Tom

Dear guru's,
I want to start my first WPF-exercises.
Can you give me a hint, which components I need to download for this purpuse?
(e.g. NetFramework 3.0)
Another stupid question: Are WPF-applications possible on Win-XP?
Thank you for your help

Hi there
In order to run WPF applications, you'll need at least .NET 3.0, but if possible, use 3.5, which are both supported by xp as well. If you're a novice developer, have a look at Visual Studio 2008 Express for Windows - it'll give you everything to get started.

Happy coding!

C# Express 2008 has built in support for WPF projects - nothing extra required - as has Visual Studio 2008. Most sites with articles on WPF seem to use expression blend for UI designing, but it's not necessary - just easier.
No problems running WPF apps on XP!

What do you mean?
only two letters away from being an asset

I think he means an application wide keypress event handler.

Have a look here[^]. I haven't tried it but it looks like it'll do what you want.

Hi,
yes you can create system-wide hotkeys.
My Code Rescue article[^] uses them (but does not mention it in the article itself).
There is some P/Invoke involved, calling Win32 functions.

Set your form's KeyPreview property to true then use the form's KeyDown, KeyPress or KeyUp events.

Bitmap class has several constructs. Choose the one that meets your needs
