Yeah, forgot the void, but it won't compile for me in my app (admittedly much larger and complex than the example I posted).

Probably the best way to check this is to start systematically checking the properties and methods on your publically exposed types that expose something that isn't publically accessible. Obviously, starting with the one that caused the compilation error.

If an abstract class contains one method with only declaration and with no body, will it gets executed with no errors? Thanks in advance
|
|
|
|

Hi,
yes the code will be executed as the Abstract Classes are not used to create objects.
An abstract class is designed to act as a base class (to be inherited by other classes). Abstract class is a design concept in program development and provides a base upon which other classes are built.
To know more about the same, please refer to the below mentioned link:

Well, you can't really execute an abstract method. A class would have to be derived from the abstract class and implement the abstract method. Then you can execute the actual method.
An abstract class may contain a non-abstract method, it will require a body, but that body may be empty (or at least an appropriate return statement).

Hello everyone,
Meta data for an assembly describes the exposed and referred types of the assembly. I am wondering the the debug version and release version of the assembly, are the meta data the same or not?
thanks in advance,
George

Well, depends what you mean. Some of it has to differ, but the 'exposed and refered types' obviously do not.

I have a C#-Component with some logic implemented.
This logic is used from my web application and a C++ application.
Debugging the C#-Component from the web application is no problem.
But now I am faced with the problem to debug the C#-component from the C++ application which is unmanaged code.
If I start the application and try to attach the debugger after that, the MS Visual Studio 2003 raises an error message with the following info:
"Unabled to attach to the process. There is no managed code running..."
So I tried the following. I made (for debugging only) a global instance of my C#-component with is loading at start up of the C++ application. Now, when I try to attach the debugger the MS VS says only:
"Unabled to attach to the process." So the debugger noticed my managed code running but he cant attach nevertheless.
So do you have any ideas what the problem could be?
Thanks in advance.

I wish to build a multi sized array to read data from a specific source (in this case an SQLDataReader). The following code DOES work however it seems fairly drawn out and I'm certain that it could be done in less code. I'm fairly new to C# hence why I think my way of doing it possibly isn't the most efficient.
Without giving the array a size I get a compiling error and thus have to have two while loops to give the array a size. Is there a better way to do this?
Many thanks.. Ant
MSSQLConn.Open();
SqlCommand MSSQLCommandSelect = new SqlCommand();
MSSQLCommandSelect.CommandText = "SELECT TrackingID FROM Tracking WHERE " + FieldToSearch + " = " + DataToSearch;
MSSQLCommandSelect.Connection = MSSQLConn;
SqlDataReader reader = MSSQLCommandSelect.ExecuteReader();
int[] TrackingIDs;
int i = 0;
while (reader.Read() == true)
{
i++;
}
reader.Close();
reader = null;
reader = MSSQLCommandSelect.ExecuteReader();
TrackingIDs = new int[i];
i = 0;
TrackingIDs[0] = -1;
while (reader.Read() == true)
{
TrackingIDs[i] = (int)reader[0];
i++;
}
reader.Close();
MSSQLConn.Close();
return TrackingIDs;

Only use ArrayList if you're stuck with .net 1.1, if you have 2.0 and above you're better off using the generic List.

Hi,
I want to write a GENERIC method to retrieve a property from an object from the specified index.
For example, I have three classes as listed below . OrderHeader contains a list of OrderDetail and OrderDetail Contains a list of OrderItem.
public class OrderItem<br />
{<br />
private int _itemId ;<br />
<br />
public int ItemId<br />
{<br />
get { return _itemId; }<br />
set { _itemId = value; }<br />
}<br />
private string _ItemName ;<br />
<br />
public string ItemName<br />
{<br />
get { return _ItemName; }<br />
set { _ItemName = value; }<br />
}<br />
}<br />
<br />
<br />
public class OrderDetail<br />
{<br />
<br />
private IList<OrderItem> _orderItemList;<br />
private int _orderDetailId;<br />
private int _amount;<br />
<br />
public IList<OrderItem> OrderItemList<br />
{<br />
get { return _orderItemList; }<br />
set { _orderItemList = value; }<br />
}<br />
<br />
public int OrderDetailId<br />
{<br />
get { return _orderDetailId; }<br />
set { _orderDetailId = value; }<br />
}<br />
<br />
public int Amount<br />
{<br />
get { return _amount; }<br />
set { _amount = value; }<br />
}<br />
}<br />
<br />
public class OrderHeader<br />
{<br />
private int _orderHeaderId;<br />
private IList<OrderDetail> _orderDetailList;<br />
<br />
public int OrderHeaderId<br />
{<br />
get { return _orderHeaderId; }<br />
set { _orderHeaderId = value; }<br />
}<br />
<br />
public IList<OrderDetail> OrderDetailList<br />
{<br />
get { return _orderDetailList; }<br />
set { _orderDetailList = value; }<br />
}<br />
<br />
}
First input to the method is an object (Example: OrderHeader Object)
Second input is a string with the required propety name and stirng. --> "OrderHeaderObject.OrderDetailList[1].OrderItemList[0].ItemName".
And the output should be the ItemName string.
What would the best way to acheive this..?
Can i achive it by using the method InvokeMember() method..? Example: OrderHeaderObject.GetType().InvokeMember(....)
Where did error begin?

You mean you're hosting an IE control in your app?

Go to Google, Yahoo, or any other search provider you want to support. Search for some word and note the URL of the page that gets returned. Should take you 5 mins to get that working from your own TextBox.
Cheers,

Hiii...
I am receiving this error :--->
Server encountered an internal error. For more information, turn on customErrors in the server's .config file.
Server stack trace:
Exception rethrown at [0]:
at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
1) After googling, I found that customErrors mode="off can help.
Presently its True on Server side. Like this
RemotingConfiguration.CustomErrorsEnabled(true);
2) I am using .Net 1.1 on the server side and .Net 2.0 on client side.
3) Not getting this problem frequently. It has only 5% chances.
4) When I debugging found some interesting stuff:
class One
{
public string m_sResult = null;
public string GetInfo(string sID)
{
try
{
if(OnRequested != null)
OnRequested(sID);
return m_sResult;
}
catch(Exception ex)
{
WriteLog(“ “);
}
}
}
class Two{
void OnRequestedHandler(string sID)
{
try
{
One.m_sReult = "Done";
}
catch(Exception ex)
{
One.m_sReult = ex.message;
}
}
}
From the client side, I am calling One.GetInfo() method.
a) Event OnRequested(sID) raised and handled by class Two and One.m_sReult is set as "Done".
b) But on client side it returns NULL and also writes Log "Server encountered and internal....." on Server side.
So suggest me, what I should do to solve this problem.
I should use customErrors mode="off for better understanding?
I would appreciate any help or suggestions that anyone can provide.
Thank you.
Sidh

Hi,
I want to know if there is any event to know if the print button on the report viewer toolbar is clicked. I want to do some database updations only if the report is printed.
The alternative is to not use the toolbar button and do the printing on some button click on the form. But i dont want to do that.
Please reply if anyone know anything abt this.
