Hi , to register your .Net DLL as a COM like stuff, you have to use regasm.exe tool, also do not forget to give the [GUID.....] attribute to your class,
you can also go by another approach of using tlbexp.exe to get a COM like dll and then register using regsvr32.
Live and let live

You're mistaken. The dll is not a COM dll, and therefore cannot be registered. What makes you think that Access should be able to use a .NET dll ? 2000 is before .NET was released.

WMI is what you need for most of this. To get the drives is easy, there's an API that returns them all, in System.IO, from memory.

hi there.
to use WMI, visit "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/wmi_reference.asp"
here is an example to collection physical drive info.
namespace: System.Management
ConnectionOptions conOpt = new ConnectionOptions();
conOpt.Username="administrator";
conOpt.Password="password";
ManagementScope localScope = new ManagementScope("\\pcgnadeem",conOpt);//computer name
ManagementObjectSearcher searcher = new ManagementObjectSearcher();
//searcher.Scope=localScope;//required only for remote computers
ObjectQuery query = new ObjectQuery("Select Name from Win32_LogicalDisk Where DriveType=3");
searcher.Query=query;
ManagementObjectCollection ResultsCollection = searcher.Get();
foreach(ManagementObject obj in ResultsCollection){
MessageBox.Show(obj["Name"].ToString());
}

hi,
in the link below is an example of what I want to achieve, but in a smart client winforms app.
in my app, the listboxes would be directly on the Employee add/edit form.
http://examples.codecharge.com/ExamplePack/ManyToManyListboxes/ManyToManyListboxes.php?emp_id=20
i've been googling for days, but haven't found an example, and I am too unexperienced to figure it out by myself.
any help or pointing in the direction very much appreciated
am using VS2005, in a C# Windows application.
Let's say I want a form to add a new Employee and assign projects to him on the same form by having a list of available projects and a list of selected projects.
Should the first list box be databound to a bindingsource ? When I assign a project to the employee it should dispaear from the available list, but not from the underlying database.
The selected projects should add records to the Employee_project table (join table for the many to many relationship)
I'd like to see an example of this using bindingsources as the datasource for the listboxes.
i'm using nettiers/codesmith

process.start can be used to open a file with the default program.

I want to draw a line on the panel of another form(such as Form2),part of
the code :
private void button3_Click(object sender, EventArgs e)
{
Form2 form = new Form2();
Graphics graphics = form.panel1.CreateGraphics();
graphics.Clear(System.Drawing.SystemColors.Control);
Font drawFont = new Font("Arial", 10);
SolidBrush drawBrush = new SolidBrush(Color.Red);
Pen pen = new Pen(drawBrush);
graphics.DrawLine(pen, 0, 0, 100, 100);
form.ShowDialog();

Try this
private void button3_Click(object sender, EventArgs e)
{
Form2 form = new Form2();
Graphics graphics = form.panel1.CreateGraphics();
graphics.Clear(System.Drawing.SystemColors.Control);
Font drawFont = new Font("Arial", 10);
SolidBrush drawBrush = new SolidBrush(Color.Red);
Pen pen = new Pen(drawBrush);
form.Show();
graphics.DrawLine(pen, 0, 0, 100, 100);
}

Thank you very much!But when I move the Form2,the line disappear.
|
|
|
|
|
That is because the form gets damaged. You have to redraw the line each time the form gets damaged.
|
|
|
|
|
You're confusing the concept of "drawing a line" with "creating a static line control". Drawing is done in response to a paint message by Windows. The call to form.Dialog() causes the instance of Form2 to repaint itself. Since the form doesn't contain a red panel with a red line, it isn't shown when the form is displayed.

Thank you very much!But could you conduct me to solve the problem,"creating a static line control".

Search the forums and articles for "single instance", these are the right keywords you are looking for.
