Ok I'm not exactly sure if this is the correct place to ask this, but here goes.
I am using a method call AddControl that takes two strings as arguments. The first argument is the "Class Name" of a control, the second is some sort of license code for the control.
For Example, If I wanted to add a Calender, I wold call the function like this:
object obj = AddControl("MSCAL.Calendar", "")
This would add the Microsoft Calendar control and pass me back a pointer so I could access it's methods and properties.
Ok my question is this, I now extend the Calendar control by creating a new c# Control Library project. I can compile and use this control by dragging it from the toolbox and placing it on a form, but I cannot get it to load using the method above. I tried calling it by it's class name TestControl.TestControl, but that doesn't work. I have tried using the GUID as the Class name, but that doesn't seem to work either.
Any help would be appreciated.

Don't you have to add the .dll to your project?
|
|
|
|
|
Of course I added the .dll file as a reference to my project. In fact I even added the control library project as a reference to my current project.
I can add my control to a windows form and it works just fine. It's trying to add it through the specified interface that I am having difficulty with.

Ok, I solved my own problem so I'm going to post it here.
Instead of using the Custom Control Library as a separate project, I created the control from within my project. The functionality appear to be the same, other than I can't use the control from yet another project.
I guess you would say this is a work around, but not a solution.

Hi
I am using Visual Studio 2005 and MS Access 2003 to create a Windows application in C#.
I have a DataGridView and I programmatically add a DataGridViewComboBoxColumn to the DataGridView. I populate the ComboBoxes in the DataGridViewComboBoxColumn from a lookup table in the database and bind the DataGridView to a DataTable loaded from another table in the database.
However the correct item in the ComboBox does not get selected. In fact nothing is selected in the ComboBox. Looking at my code it feels to me that I am missing something in my code, but I do not know what.
The doctorTable has a Primary key: Doctor_ID
The patientTable has a Foreign key: Doctor_ID
Using the following code snippets:
private void DataController()
{
try
{
this.LoadData_Controller();
this.FormatDataGridView();
dgvPatients.DataSource = patientTable;
}
catch (Exception ex)
{
throw ex;
}
}
private void FormatDataGridView()
{
try
{
#region Format Doctor column
DataGridViewComboBoxColumn comboboxColumnDoctors = new DataGridViewComboBoxColumn();
comboboxColumnDoctors.DataPropertyName = "Doctor";
comboboxColumnDoctors.HeaderText = "Doctor";
comboboxColumnDoctors.DataSource = doctorTable;
comboboxColumnDoctors.ValueMember = "Doctor_ID";
comboboxColumnDoctors.DisplayMember = "DrName";
dgvPatients.Columns.Insert(3, comboboxColumnDoctors);
#endregion
}
catch (Exception ex)
{
throw ex;
}
}
Any help will be greatly appreciated.
Thanks.

Check DataBindings property. I know combobox has this property and hopefully DataGridViewComboBox has it as well. Here you can make each control be ware of the other. If property is not there then simply write some code. For example, when the comboBox is selected, select the appropriate patients which have the foreign key.

you must remove dgvPatients.Columns.Remove("Doctor_ID");
from the DataGridView

I had a dll referenced in my project having namespace Utilities. I can access the methods in the namespace by writing Using Utilities at the top of my project and directly I can use Utilities.Class.Method.....
Plz let me know what the exact difference between these two ways.
Thanks,
Bhuvan....

No difference at all. Except without using Using you have to write Namespace.Class.Method everywhere you want to use that method.
Hope can help
[Edit]
Also it's worthy to search Using in MSDN.

Not quite. By prefixing the class with the namespace you can avoid name clashes. If two (or more) usings have the same class, then you will get a compiler error if you don't specify the namespace.
Likewise, if you forget to include your namespace via using and there's another namespace using your class name, then you might accidentally use this class. Sure, the signatures won't match, but it can give you some headache because you might not know what the compiler is complaining about.

It's a batch file used to compile and link a program.

It's not. C# uses MSBuild. Google that or look in MSDN.
