Re: Can you declare an array of mixed Types?

Either create an object array as Harold sugested, or create a class that holds the various types you need in it's properties and create an array of your class - this will save a lot of boxing/unboxing.

Not yet; C# 4.0 brings in Tuples, but I don't know how these would interact with arrays and it hasn't be released yet

Make your mind up!
Are you doing this in Visual Basic or C#.
You should not post questions on more than one forum!

Make up your mind and then delete the message that is in the wrong forum.

I am posting the reply answer of help.
I am advising you on the correct behaviour on CP forums.

Now for goodness sake, decide if you want a C# answer or a VB answer and delete the one you don't want.

The event is automatically triggered when you double-click an item. What are you trying to achieve?

You can't put a class name in a using, only the namespace.

using NamespaceTwo;

namespace NamespaceOne
{
    public class ClassA
    {
        ClassB b1 = new ClassB();
        NamespaceTwo.ClassB b2 = new NamespaceTwo.ClassB();
    }
}

namespace NamespaceTwo
{
    public class ClassB
    {
        //
    }
}

You need to be specific about exactly how it isn't working. I'm going to assume that you got an error that said something like Are you missing an assembly reference?

If they are then you have to add a reference to the assembly the class you want to use is contained in.

To do this, right click on the project (in the Solution Explorer) and select "Add reference..." in the context menu. In the dialog select the "Projects" tab and then select the project the class you want to use is in.

Your using should then work.

Make sure the class you're trying to use is marked as public, otherwise it won't be visible outside its namespace.

BindingSource Filter

I have to list boxes...and i have a datagrid with binded to complete table..and i am using DataGridCombocolumn with displaystyle as nothing to display the values from master tables in relation instead of their IDs...

On selection change event of second list box i put this filter...values in both list boxes are selected...it shows correct values in debug mode........

MyBindingSource.Filter = "Column1="+cbCol1.SelectedValue+" AND Column2= "+cbCol2.SelectedValue;

it gives following error

Syntax error: Missing operand before 'And' operator.

Re: BindingSource Filter

ABitSmart1-Apr-09 7:27

You might be missing the ' (quote). Try it this way,
MyBindingSource.Filter = "Column1='"+cbCol1.SelectedValue+"' AND Column2= '"+cbCol2.SelectedValue+"'";

See the example here, Link[^]

shafiullah1231-Apr-09 8:55

When i am doing it like that it gives error cannot convert System.Int32 to System.String

Actually both are Primary key IDs in individual master tables....but the value coming here is string...If i am not using AND clause this is working fine with individual listbox filtering it is auto converting those strings...Its only then when i want to filter by values from both columns its creating prob...I am not facing any prob with combo box in the same situation.......Its the only list box thats irritating

Re: BindingSource Filter

jaypatel5121-Apr-09 20:33

(("Column1="+cbCol1.SelectedValue.ToString()+") AND (Column2= "+cbCol2.SelectedValue.ToString()));

This might work...
And one more thing.

it might be && inspite of AND

But not so sure. .

opacity problem

Try1-Apr-09 5:40

1-Apr-09 5:40

Hi All,

I am using C#. I have a empty Form. When i move mouse on the Form, i am displaying the x and y position of mouse using DrawString() method.

Graphics grx = e.Graphics;
string xy = "X: " + cursorPos.X.ToString() + "\nY: " + cursorPos.Y.ToString();
grx.DrawString(xy, font, brush, cursorPos.X, cursorPos.Y);

The above code snippet is in Paint event. Hence the x and y values move along with cursor.

My problem,
When i change the opacity of Form from 100% to 10%, the Form becomes transparent. Even x and y values (displayed using DrawString) becomes transparent (faint).
I want the x and y values to be displayed clearly even if Form is transparent. How can i achieve it?

Thanks in advance.

Re: opacity problem

Hmmm not sure if will work but try the following...

Set the backcolor of your form to a color not used for you text, the set the tranparencykey to match.
then put a panel on your form with backcolor as Transparent.
then do your paint code to the panels Paint Event.

hopefully it will work

EDIT:

just tested and works fine, just need to set the FormBorderStyle to None
