it is possible. the next question is, is it managed c++ or unmanaged c++

as i have it, the easiest way to see that is that managed c++ has a 'ref' somewhere before class names. and unmanaged doesn't.

Dropdownlist

Hi all,

I have got 3 dropdownlist, one would be interrelated with other.

On a particular selection of the 1st dropdownlist, the 2nd and 3rd dropdown list should be enabled, if not only the 2nd dropdown list must be enabled.

In the selected index change of my dropdownlist 2, my 3rd one is getting disabled, even though on particular selection of my 1st dropdownlist is enabling both(which shouldn't happen).

I'm using Page.RegisterStartup script for enabling / disabling the items. The below code is written in the selected index change of 2nd dropdownlist(without the bold text, my 3rd dropdownlist is always disabled", though my 1st dropdownlist is enabling it.)

string focusScriptSetVal = "<script language='javascript'>" + " document.getElementById('" + 1stdrpdwnlist+ "').disabled=false;document.getElementById('" + 2nddrpdwnlist.UniqueID +"').disabled=false;document.getElementById('" + 3rddrpdwnlist+"').disabled=false;;</script>";
Page.RegisterStartupScript("focusScriptSetVal", focusScriptSetVal);

Shouldn't that be 1stdrpdwnlist.ClientID ?

No, it doesn't. You are creating an instance of the base Form class, not your derived class, called Form1, or whatever. This base form has no controls on it.

Depends what you mean. Can you create a screenshot ? Yes. Can you create something and plug it into the C# forms designer ? No. Can you create a flash UI and host it in a Winform ? Yes. Can you create a Flash UI and then write C# code that interacts with elements in the form ? I don't think so.

How to search a field from a text file using Visual C#

• The Program should search for the Staff with the Surname and Firstname entered in the file and display its Course
• If not found, an appropriate Message should be displayed and the focus should return to the Surname.

Please Note that the program should work with any file used. (YOU DO NOT KNOW WHAT IS INSIDE THE LISTBOX!)

Under some circumstances a listbox tries to have a height corresponding to
an integral number of text lines (and fails at this when the hor scrollbar appears).

The best way to observe this is to load the listbox with a lot of text lines...
