No, you will need the .NET framework which is not on those OS' by default. (same as Java needing the JVM)

MDI Control.

I have some trouble with my MDI-Window. The Child forms get UNDER the surface.. Take a look here:
http://basbroekman.nl/Img/Members/Media/IDEMdev.JPG[^]

I want the forms to autoscale with the maximal ground they get.. and don't go over other forms and so on.

The fact that forms can be scaled, is the only reason that I made a MDI-window. I am out of ideas, if nobody know a answer, than I going to make a sizeble panel.

Keep breathing, foks!

Various Screen resolutions

Hi all,

I am creating a windows application on 17'monitor with 1280 X 1024 as the resolution
now when i execute the same application on different machine the size of the forms
differ.

How can i create forms that will take the screen size dynamically and all the controls on
that form should be resized to be displayed in the same manner and location where
i had created them.

Thanks,
Pramod

You can do it.
When application starts, you must get the resolution and recount all form sizes.
Resizing controls is more simple - use Anchor property.

It's against the idea of OO programming.

consider a situation where classA which has a function f()

classB and classC are childs of classA. hence they both have the same copy of f().

now consider classD inherits both classB and classC (multiple inheritance) in which case there will be a ambiguity as to which copy of f() is called since both of them have the same.

inorder to avoid this complexity c# provides a multiple inheritance of interfaces and not classes since u give the definitions of the functions in the class which implements them

Well, there aren't that many languages that support complete OO design. Even Java and C# aren't completely OO although they're called OO languages, as is C++.

C# is just more OO then C++.
Maybe it's clearer in other words:
In C++ we have more ways for no OO design. (eg. multiple inheritance, ...)

Coulda, woulda, shoulda doesn't matter if you don't.

In addition to the replies you already got, the clean way is supported by C#: your class can implement several interfaces.

Not really, no. At least not in any automated way. The languages are totally different, C# is closer to Java than it is to C++.

in your ascx page you have to define an ID for your dropdownlist, in this example it is "MyDropDownList".
the grid has ID MyGrid

foreach(DataGridItem dgi in MyGrid.Items)
{
DropDownList myDropDownList = (DropDownList)dgi.FindControl("MyDropDownList");
string strSelectedValue = myDropDownList.SelectedValue;
}

not shore what you meen, but I don't think cookies gona help you with this.

You have to call your update method, something like

<br />
public void updateMySQL_table(int rowID, string valueFromDropDownList)<br />
{<br />
string sql = null;<br />
DataManager dm = null;<br />
<br />
try<br />
{		<br />
	sql = "UPDATE someTable SET strTheColumn = 'valueFromDropDownList' WHERE someRowID = " + rowID.ToString+ ";";<br />
				 <br />
<br />
	dm = new DataManager();<br />
	dm.ExecuteSQL(sql);<br />
				<br />
}<br />
catch(Exception e)<br />
{<br />
	throw new Exception("updateMySQL_table failed. " + e.Message);<br />
}<br />
finally<br />
{<br />
	if (dm != null)dm.Dispose();<br />
	dm = null;<br />
}<br />
}<br />

each row in your Grid should also contain a value where you have set the rowID, something like

<br />
<asp:TemplateColumn><br />
<ItemTemplate><br />
	<input type="hidden" runat="server" id="inRowID" value='<%#DataBinder.Eval(Container.DataItem, "rowID").ToString()%>'><br />
</ItemTemplate><br />
</asp:TemplateColumn><br />

This you also have to retrive the rowID

<br />
HtmlInputHidden _inRowID = new HtmlInputHidden();<br />
DropDownList myDropDownList = null<br />
foreach(DataGridItem dgi in MyGrid.Items)<br />
{<br />
_inRowID = (HtmlInputHidden)dgi.FindControl("inRowID");<br />
myDropDownList = (DropDownList)dgi.FindControl("MyDropDownList");<br />
updateMySQL_table(int.Parse(_inRowID.Value), myDropDownList.SelectedValue);<br />
} <br />

Hope it helps
Thomas
