What to cast object of type IErrorInfo into for access via C#

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :.NET Framework
 

I have an method (handler) in C# that receives an event raised from a C++ COM component; the parameter is an object (the object is an interface IErrorInfo frmo C++)

I need to access the IErrorInfo object for the message ... but cannot cast it correctly ... I keep getting invalid cast exceptions .. Ihave tried:

void

 

executor_NotInitialized(object pErrorInfo)

{

_Exception iEx = (_Exception)pErrorInfo;

System.IntPtr pEx = System.Runtime.InteropServices.Marshal.GetComInterfaceForObject(pErrorInfo, typeof(_Exception));}

both result in invalid cast exceptions?

I do not know what to cast the object to for access to the underlying IErrorInfo ?

Using IPC only channel getting Unable to cast object of type 'System.Runtime.Remoting.Identity' to

  

I have a remoting application that is using delegates to preform callbacks between processes. I found that if I don't use a TCP channel at all and only initialize an IPC channel that the callback delegates start throwing the following error after about a minute has passed.

From what little I could find on Google it seems to be a Lifetime Service management issue but all the classes that the delegates belong to return null from InitializeLifetimeService which should give the object an infinite lifetime.

With the TCP channel initialized the issue doesn't happen, but I would like it to use the IPC channel if all of the processes are on the local box.

type object parameter

  

Hello!

I have a problem I can't figure out.

I've been trying to add a listbox with multi select enabled as a parameter to my select statement in sqldatasource.

So i created a function like this :

string strItemTypes = "";
foreach (ListItem li in lbItemType.Items)
{
   if (li.Selected)
   {
      strItemTypes += "," + li.Value;
   }
}
strItemTypes = strItemTypes.Substring(1);


which gives me the selected items like this for example : "1,2,3"...
Then I've been trying to add it to my sql select statement :


SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name, tblStockItems.Description, tblStockItemTypes.TypeItem, tblStockItems.Notes FROM tblOfficesItems INNER JOIN tblStockItems ON tblOfficesItems.fkItem = tblStockItems.idItem INNER JOIN tblStockItemTypes ON tblStockItems.fkTypeItem = tblStockItemTypes.idTypeItem WHERE tblStockItems.fkTypeItem IN ( @fkTypeItems )


using a hiddenfield with a controlparameter of type=object
but it just don't seem to work, seems like the data just won't bind or something and I don't get any errors so I'm confused!!

then i tried this :


SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name

How to access the refrenced table fields in Ilist object of table MVC asp.net

  

Hello,

I have 2 tables, master, detail. 1.master table have fields (id, username, plan)-->id is primary key (PK) 2. detail table have fields (srNo,id, worksummary, ... )--> srNo is PK.

I have created foreign key relationship from detail to .master table for "id" field.

the code is:

IList<detail> objDetail=new List<detail> (); 
IList<master> objMaster = new List<master> ();
string[] sarray = queryFields.Split('|');//

for (int i = 0; i < sarray.Length; i++)
{
string[] sfields = sarray[i].Split(',');

if (sfields[0] != "")
{

objDetail.Add(new _detail { Id = count , modify = sfields[1].ToString(), verified = sfields[2], I});


}
}

I have problem to add fields in "objDetail" using Add method. But I am unable to access the reference field "Id" , rest of the field of detail table can be accessed using objDetail.

How can I access the "Id" field from objDetail object to add in IList.

I want to solve this problem
