[Alex. O. Koranteng]

I have a clas file in App_code folder which is being called during pag_load
to load a datatable. I am getting the error below and the code for Page_Load
is as follows
Any suggestions will be appreciated. I can email you the zipped file for the
entire project if necessary


Line 20: if (Page.IsPostBack == false)
Line 21: {
Line 22: DataTable dtData = cCommon.GetEmployees();
Line 23: this.ddlEmployee.Items.Add(String.Empty);
Line 24: foreach (DataRow drData in dtData.Rows)

Hi

If I am reading your code correctly the class name is 'cCommon' and it
has a method 'GetEmployees()' that returns a DataTable.

The error suggests that the method has not been declared properly in
the code for the class causing GetEmployees() to be out of scope.
For your calling code to work the header should be something like
this:

public static DataTable GetEmployees()

Note the use of the keyword 'static' which allows the method to be
called without creating an instance of the class cCommon.

It seems that cCommon class is not there. Check your book, there
should be a reference to that class

Alexey,


Thanks for the suggestion. I have checked my cCommon class file and the
GetEmployes method has been using declared as a Static method.
Can I email you the solution file you give me your email address.

Could you show me how and where cCommon is initialized? You can send your
project to (e-mail address removed). Please update here after sending the
project in case I missed that email.

Allen,

I am sending you the project file in a few minutes. About how the cCommon
file is being initialized, I see a method shown below. I cannot find anywhere
in web.config file pointing to the Databaseconnectionstirng strg name. Could
my erroir be due to this. Not sure. Any suggestions. Please check your inbox.
The error I am getting starts with with the SimpleUpdate.aspx page and
happens for all other pages within the app. Once again, thanks for being very
supportive.
