vb.net windows application code to c#,asp.net web application code

[manjitsarma]

I have changed the following original vb.net window application code

Public Overrides Function SetTheme(ByRef frmObj As 
System.Windows.Forms) As Boolean
 

into c#.net as-

public override bool SetTheme(ref System.Windows.Forms frmObj)
 

..

Later on changed to

 
public override bool SetTheme(ref System.Web.UI.Page frmObj)
 
 

.....since it is to be used in ASP.NET web application(webform).

Then I m getting errors in following code

frmObj.TransparencyKey = this.TransperncyColor;
 

Error:System.Web.UI.Page does not contain definition for
TransparencyKey

frmObj.BackgroundImage.FromFile(this.BackGroundImage)
 

Error :System.Web.UI.Page does not contain definition for
BackgroundImage.

Again getting errors in following code.

foreach (Control cntl in  frmObj.Controls)
   {
 
            if ((cntl) is DropDownList)
            {
    cntl.ForeColor = Color.Red;
 
            }
           else
           {
    cntl.ForeColor = Color.Black;
           }
 
    }
 

Error:System.Web.UI.Control does not contain definition for Forecolor.

I have used namespace 'using System.Drawing'.

How to debug it ?

Moved from the Java(!) to the .NET forum.

All of those are specific to windows application controls. Just remove them.

[manjitsarma]

But I need to use them in web application.so could you tell me what are the other ways I can approach ? and is it the correct way to convert-

public override bool SetTheme(ref System.Windows.Forms frmObj)
 

into-

public override bool SetTheme(ref System.Web.UI.Page frmObj)
 

...to use in ASP.NET web application.Is it for this conversion,I am getting the errors ?

But they are no longer applicable. Like the concept of themes is a windows only thing (determines if your program looks like windows2000 or winxp)

And another one was setting a transparency color on the form. That is done with CSS not backend code.

You should be looking up the individual commands to see if they even apply to a web-based application

ok.Thanks for the suggestion :)
