hi there:
i have a dataset called "Employees", that have two tables "employees"and "jobs",employees have a foreign key called "jobid" that refrence the primary key "jobid" in the "jobs" table and tied together,i have a datagrid that each record of it have columns from "employee" table and have one column called "jobDesc", i write the following function to get the "jobDesc" column from "jobs" table by the foreign "jobid"column in the "emplyee table...........I want to translate this function into method in c#
Public Function BindJob(ByVal o As Object) As String
Dim drv As DataRowView = o
Dim dr As Employees.employeeRow = drv.Row
'Dim dp As Employees.jobsRow = dr.GetParentRow("jobsemployee")
'Return dp.job_desc
' Alternatively, since this is strongly typed:
Return dr.jobsRow.job_desc
End Function
|
|
|
|
|
public String BindJob(Object o){ //forget about ByVal
DataRowView drv = (DataRowView)o;
Employees.employeeRow dr = drv.Row;
return dr.jobsRow.job_desc;
}
|
|
|
|
|
this casting is not working
DataRowView drv = (DataRowView)o;
error msg:
Exception Details: System.InvalidCastException: Specified cast is not valid.
|
|
|
|
|
No my fault 
If you don't pass a DataRowView, is can not be used as a DataRowView.
Try Console.WriteLine(o.GetType()); to find out, what is really is.

Does anyone know how to loop through all icons in an embedded folder and populate an imagelist. As seen below, I have an embedded folder Prud.Library.Icons.State which contains a set of icons. I would like to add all Icons in State to an ImageList regardless of their name.
Does anyone know how this can be done?
Thanks heaps. 
Note: string sIconName = "Prud.Library.Icons.State.Icon1.ico";
System.IO.Stream objStream = null;
System.Drawing.Icon[] objIcon;
try
{
/*
* Stream Icon and add to ImageList
*/
objStream = this.GetType().Assembly.GetManifestResourceStream(sIconName);
if (objStream != null)
{
objIcon = new System.Drawing.Icon[1];
objIcon[0] = new Icon(objStream);
}
}
catch (Exception err)
{
throw err;
}
finally
{
/*
* Dispose of Stream Object
*/
if (objStream != null)
{
objStream.Flush();
objStream = null;
}
}
return objIcon;

Hi,
Is there any way i can read remote machine registry in c#.
I will appreciate if some one give me code to read remote machine registry.
Regards,
Waqar.

You can read from a remote registry using the following static method:
Microsoft.Win32.RegistryKey.OpenRemoteBaseKey(...)
However, according to the MSDN documentation, the following must be ensured:
In order for a key to be opened remotely, both machines (the service, and client) must be running the remote registry service, and have remote administration enabled.
Cheers,

You also only have access to the HKEY_LOCAL_MACHINE and HKEY_USERS keys

Subject says it all. Can a function return an array of delegates?
|
|
|
|
|
public class Test {
public delegate void DelegateExample(string[] args);
public static DelegateExample[] GetDelegates() {
return new DelegateExample[] {
new DelegateExample(Test.Main),
new DelegateExample(Test.Main)
};
}
public static void Main(string[] args) {}
}
Regards,
Jeff Varszegi

Or even better look at delegate.GetInvocationList()
leppie::AllocCPArticle("Zee blog");
Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

How would I use that with a function though?

I need to know how to disable the user's ability to add new rows to the DataGrid based on a DataTable. I have a table that represents options that can be checked on and off with a boolean column. It is a static list of options, so the user shouldn't be able to add new rows. The only thing in the table that is not read-only is the true/false value of the boolean column. I hope I am just overlooking some obvious setting in the TableStyle (I am programmatically creating the style). Any help would be greatly appreciated. Thanks.

DataGrid doesn't have such an option, neither DataTable. But DataView has:
AllowNew, plus AllowEdit and AllowDelete. The simpliest way is to set as DataSource of the DataGrid a DataView of your DataTable, and set AllowNew =false.
If you can't set as DataSource a DataView (and DataSource is a DataTable), then you still have a chance , since the data grid actually uses the DefautView of a DataTable . So, you can do something like MyTable.DefaultView.AllowNew=false;
If your DataSource is a DataSet then you can do something like this:
CurrencyManager cm =(CurrencyManager)BindingContext[MyDataGrid.DataSource,MyDataGrid.DataMember]
// Cast the IList to a DataView to set the AllowNew property.
DataView dv = (DataView) cm.List;
dv.AllowNew = false;
Best Regards,
Daniel Zaharia

Thanks that did the trick. I used...
myTable.DefaultView.AllowNew = false;

I am trying to find a way to take records from a ListView control and move them to the system clipboard so they can be pasted directly into Microsoft Excel.
I have found the DataFormat class and see it supports a CommaSeparatedValue format, but I cannot get it to work correctly.
I have tried this, just as a test...
string s = "1,2,3,4,5,6,7,8,9";
DataObject d = new DataObject();
d.SetData(DataFormats.CommaSeparatedValue,s);
Clipboard.SetDataObject(d,false);
But when I paste it into Excel I get
–§žý;pC¦yVk²ˆû
Have any of you ever successfully formatted data, stored it in the Clipboard so it could be successfully pasted into Excel?
