I have the variables and methods inside one class. I want to break that class into two classes so that the size of the class is reduced. That is the reason why i went for partial class concept.

I have few variables which will be used throughout the class, so they have been declared globally in that class. When i tried moving few methods to the other class file, i am not able to access those global variables which are there in the first class file.

Can you help me on this?

I don't know what this means, how is something declared globally, but within a class ? Do you mean a member variable ?

You need to post some code, so we can see what's going on.

Hi Christian,

Here is the code which i have used.

File1:
Partial Class TEWebClass
Inherits UI.Page

Protected cnn As New ADODB.Connection
Protected rs As ADODB.Recordset
Protected rs2 As ADODB.Recordse
End Class

File2:
Partial Class TEWebClass
Inherits UI.Page

Public Sub clientadd_ProcessForm()
Dim formError As Boolean
Dim itemOK As Boolean
Dim errortext As String
...
End Sub
End Class

These are two different files with the same class name. From File2, i need to access the variable cnn which is declared in File1. I tried, but not able to do it.

Can you help me.

Your code looks OK. Are you getting any error ?

Hi Navaneeth,

I tried using the cnn variable from File2, it throws the error "variable cnn not declared"

If you have any namespace defined, make sure it is same for both files.

I presume you need to keep variables in one file and methods in other, right ? So your partial class would be like

file name would be MyClass.Variables

partial class MyClass
{
    public int a;
    private string b;
    //etc
}

file name would be MyClass.Methods

partial class MyClass
{
    //Methods goes here
}

when compiled, this will act as a single class. You can access variables as you do in normal class.

No-one is going to read all of this code. This is a common problem, jscript menus showing up under controls. I'm not sure what the solution is, it may involve finding another control, or reorganising your page layout.

Firstly you try to check your calendar z-index

I try to check with you. your calendar can be override combo.

Only panel problem should be same with last time I meet up problem.

I think so that this is Calendar Issue. Last time I also think like that, I try to set with css. But it is not OK.

Solution is here. Previously .net 1.1 is using like this. This is problem.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

Now .net 2.0 is solved ready of this problem.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

After migration from .net 1.1 to 2.0 is never changed of this. Anyway you can try to guess and fix.

I created one website with the same webservice settings and was able to make it work.
The best thing to check this would be to debug which instance is currently null.
Also, let us know which line of code is throwing this error?

Hi Dear,

My code is here. Just have a look it.
there is one method named GetSearchResults_soap it have 4 param

I am passing it properly and hardcoded just my changed code is

srch.AuthHeader au = new srch.AuthHeader(); // This is a class file
au.UserName = Compute("pradeepraon@hotmail.com"); // property
au.Password = Compute("srch10242"); // property

srch.Srch test = new srch.Srch(); // main class file who has that method which we I am calling.
srch.SearchResults s = new srch.SearchResults(); //searchresult class

hi,

well I havent done anything like that but I think ASP .net doesnt have anything to do with writing a file on CD. I dont know ur requirements but may be u need to upload a file from asp.net and then write it on CD.

I suggest u should discuss the issue of writing on CD thru C# or VB .net (whatever ur using) on the appropriate forum

Cheers...

There is a library called XPBurn. It will work to burn CDs on the server. You can't burn a CD from a web app, on the client end.

Oh yes you can - either through ActiveX, or through the use of User Control embedded in IE!

C# has already designed away most of the tedium of C++.

If your button_click has a postback than its better to hide the panel during postback, rather than using javascript.

First of all, if it's an ASP.NET control, then the name of the control on the client is not the name on the server, you need to write the name using the server controls 'ClientID' property. Then you can use code like the above, assuming that pnlColumn is a variable that holds the client side Id, and that you put 'none' in quotes.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
