you don't have to inherit BLL from DAL
just add a reference of your DAL in your BLL and than declare a object of DAL class... and there you go..
but first confirm that DAL class functions have public access modifier.

Thanks man,
Look at thing
<br />
<br />
namespace DAL<br />
{<br />
public class DAL<br />
{<br />
<br />
<br />
public string GetInfo()<br />
{<br />
string Fname = "Vuyiswa";<br />
<br />
return Fname ;<br />
<br />
}<br />
}<br />
}<br />
<br />
And i have referenced it and see and never worried about inheritance, and try to call the DAL Functions like
<br />
namespace BLL<br />
{<br />
public class BLL<br />
{<br />
string Fname ;<br />
<br />
DAL.DAL objDAl = new DAL.DAL() ;<br />
<br />
objdal.GetInfo();<br />
<br />
<br />
}<br />
}<br />
<br />
From the Above Code, am Successfully creating an object of a class DAL and i want to call the DAL Function Getinfo() and the intelisense does not even popup to give me confidence that the object is realy referenced
to the DAL Class.
what is wrong that am doing?
Thanks

Is that a direct copy paste? Unlike VB, C# identifiers are case sensitive... objDAl and objdal are not the same thing

hi
you are right i have changed it to be the same, but still intellisense has not Confidence in that line. look at the way i created the Objected of a class. do you see anything wrong.
i know difference between vb and C# it will be like this
vb.net
<br />
<br />
dim objDAL as new DAL.DAL <br />
objDAL.GetInfo()<br />
<br />
C#
DAL.DAL objDAl = new DAL.DAL() ;<br />
<br />
objDAl.GetInfo();
Thanks

You only need a main method in the project that is the actual application. The main method is the starting point of the application, so a library project doesn't have a main method.
It works exactly the same way in VB.NET, but there the file with the main method might not be visible by default.

Thanks man
i think that nice.
Now for in case in this Situation i want to call the Functions of a BLL in my front end (form) and if double click the form to see the code i will see the same thing i used to see in vb, i means the form load event or so on, what happens to the main Function, should i create my own or should i continue the way i did in vb and code on events ?
Thanks

When you create an application project, the main method is created for you. For a windows form application, the main method creates a form and runs it.
As long as the application uses that form as main form (simply runs as long as that form is open), you don't have to bother with the main method at all, just use the events in that form.
Despite everything, the person most likely to be fooling you next is yourself.

Hi man
Then it will be very easy to convert to C# from vb.net. thanks man, am still wondering whats happening to that object of the DAL class that does not give me an option to use the function in the DAL
Thanks

If you compile the code, the error message will tell you that you can't call the method because it's private.

Hi ppl,
I am working on a project where excel sheet has to be generated.
In the end i have added this piece of code.
theWorkbook.SaveAs(SourceFile, Type.Missing, "", "", false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
ExcelObj.Quit();
Marshal.ReleaseComObject(ExcelObj);
theWorkbook = null;
ExcelObj = null;
but somehow its not removing the excel frm TM. and when i try to generate Excel again it gives error "Its already used by some program"

You are trying to release only the excel object. Whcih actually houses the workbook object which again houses the sheet objects.
Just by releasing the excel object the other object may not be releases and the excel object remains in the memory.
If you can have a look in this article by antony100
(http://www.codeproject.com/KB/office/ReleaseExcelObject.aspx)
He is calling the Marshal.ReleaseComObject(Reference); against workbooks then against the excel object.
You will need to do the same to get the excel disposed from the mem.

Hey Guys!
I downloaded the source code to Paint.Net by Rick Brewster. While browsing the code, I noticed that some the classes are being passed by Type. The method that accepts the type then must cast it into a physical class. Here's an example:
private void SetPage(Type pageType)
{
ConstructorInfo ci = pageType.GetConstructor(Type.EmptyTypes);
object obj = ci.Invoke(new object[0]);
WizardPage page = (WizardPage)obj;
...
If this method more efficient, I'll be making some changes to my code. Can anybody give the scoop on this?
Thanks,
Richard

That is not casting or passing objects.
That is a factory method.
They pass the type and the method _creates a new object_ of the type.
|
|
|
|
|
Only the type of the class is being passed. C# objects are always passed by ref, and intrinsic types by value.
Cheers,
Vikram.

Hi friends.
I have one datagridview which has one column contain combobox's (dropdown)
this code gets executed at form load
-----------------
ComboBoxCol = new DataGridViewComboBoxColumn();
ComboBoxCol.HeaderText = "SortOrder";
ViewInformationDvg.Columns.Add(ComboBoxCol);
-----------------
there are other column also.
My requirement is that i want to insert some integer number in combobox that is number of row in datagridview.
For example if first row inserted then value in comboboxx is 1
when second row inserted then value of combobox is 1,2
when third row inserted then value of combobox is 1,2,3
and so on ( rows are inserted at run time by clicking on some button)
and i want updated value of combobox to be reflected in all rows..
Hope you got my problem.
Thanks lot
Avtar.
