Hello,
In VB.NET or C# (and generaly in DOT NET)
How to get the Owner / Creator of a document / file ?
I know hot to get modification date, creation date
but not the OWNER of the file.
How to access to the Security Attributes in order to get the OWNER ?
Best regards

Off the top of my head, you can use WMI and the System.Management namespace to get the Win32_LogicalFileSecuritySetting[^] object for that file. Call it's GetSecurityDescriptor method and that will return a Win32_SecurityDescriptor[^] object, which will have the information you're looking for in its Owner property.
|
|
|
|
|
Use the FileInfo.GetAccessControl() method to retrieve a FileSecurity object. Then call FileSecurity.GetOwner() to get the owner of the file.

Can someone please recommend me good resources on distributed computing and multithreaded programming that will get me started quickly but not be too brief in their usefulness...oh and doesn't cost an arm and a leg? Nothing really jumped out at me on Amazon.com. All the books I noticed were either $100+, written in the 90's or not rated.
Thanks

now, I want to delete one record on datagrid when I checked checkbox.
there is a checkbox on datagrid.
for example; if I checked checkbox on second row. The second row will deleted.(button click event)
how can i do this...
|

Did you try searching google first?
If so you may have found this[^].
I don't know how are you binding the grid with the data but as a simple solution, I would say just a do a postback when the checkbox is checked and use the RemoveAt method of DataRowCollection.
Be careful, there is no Undo Button(Ctrl+Z) in life.

I think you need this[^] more than the textbox validation script. You should get familiar with the JavaScript first rather than asking for the solution directly.

You can use something like this-
function validateEmpty(fld) {
var error = "";
if (fld.value.length == 0) {
fld.style.background = 'Yellow';
error = "The required field has not been filled in.\n"
}
else {
fld.style.background = 'White';
}
return error;
}
function validateFormOnSubmit(theForm) {
var reason = "";
reason += validateEmpty(theForm.field1);
reason += validateEmpty(theForm.field2);
reason += validateEmpty(theForm.field3);
if (reason != "") {
alert("Some fields need correction:\n" + reason);
return false;
}
return true;
}
Replace 'field1', 'field2', and 'field3' with the correct names. You can add and subtract as well. The alert box will output a line delimited list of all error messages. Call the function like this-
<form name="demo" onsubmit="return validateFormOnSubmit(this)" action="action.aspx">
Try that out. Good luck!

Good day to all ...!!!
Hopefully I can help, I have a problem when working with reflection. I have a dll (called midll.dll) from which all classes have a class named Class1 with their respective attributes. When I try to get an object of this class have to do it by reflection through a Construtor with their parameters (I have stored on the array objects. The array objects called parametersConstructor). Therefore, with the next statement I make this job:
(The parametersConstructor have 2 values)
objObjet2 object = Activator.CreateInstance (assembly.GetType (mydll.Class1 "parametersConstructor); // The assembly is complete
The result is that the object you want to get, and I have no problem, since it does not skip any exceptions to this point.
But the problem is that I realized that one of the attributes of the object is created with one exception. The exception is the following:
atribute4Class1 -> Count = '((System.Collections.Generic.Dictionary <tkey,tvalue>. ValueCollection) (((midll.Class1) (objObjet2)). atribute4Class1)). Count' throw an exception of type 'System.ArgumentException '
Following a little more depth error (it should be noted that there was a lot of where to find the source of the error), what most caught my attention is that at some point I said the following:
Can not find the method of the object instance. (Not specified object that refers)
Personally I thought the problem was with the class, because to say that no method of the object instance, you will most likely have problems with objObjet2 casting that is specified in the original exception.
I thought it was a problem with the class Class1, but discarded, since the same class instance as follows:
Class1 obj = new Class1 ((string) parametersConstructor [0], (string) parametersConstructor [1]);
And the object is created without any problems and even less is not generated except that I mentioned earlier.
Anyone have any idea why this is? Thank you for your help ...!!!

Your writing is very difficult to understand.
I suggest you first ensure that the GetType is successful before trying the CreateInstance.

I can't seem to make the Combobox4 text to reflect the changes made and still pointing to the "Edit..."
Dim mylink As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=" + Application.StartupPath + "\Data\BW.mdb")
If Me.ComboBox4.Text = "Edit..." Then
Dim NewLink As String = InputBox("Type the desired URL to Business Warehouse Inbound", "Business Warehouse SAP")
If NewLink.Length > 0 Then
Dim Outbound As String = "UPDATE _servername SET Outstring ='" + NewLink + "'"
Dim OutFld As OleDb.OleDbCommand = New OleDb.OleDbCommand(Outbound, mylink)
Dim affectedrows As Integer
mylink.Open()
OutFld.Prepare()
affectedrows = OutFld.ExecuteNonQuery()
mylink.Close()
End If
End If
Dim sql As String = "SELECT * FROM _servername" 'Refresh
Dim da = New OleDb.OleDbDataAdapter(sql, mylink)
Dim dtSvr As New Data.DataTable("_servername")
da.Fill(dtSvr)
Me.ComboBox4.Text = (dtSvr.Rows(0).Item("Outstring")).ToString
|

Is the combobox's DropDownStyle equal to DropDownEditList. If it is, yuo should change it to DropDown. If that's not the case, use debugger to see that the ComboBox4.Text is set correctly.
Just a sidenote, you should use parameters in your sql commands instead of concatenating.
|
|
|
|
|
The Combobox4.Text shown correctly then afterwards (like refresh) it went to the selected item called "edit..." see my codes
|
|
|
|
|
So do you mean that after executing this line:
Me.ComboBox4.Text = (dtSvr.Rows(0).Item("Outstring")).ToString
the text in combobox is something else than "Edit..."? If so, when does it change back to "Edit..."?
|
|
|
|
|
I don't know. I even tried to combobox4.Items.Empty() and that would not do anything to make the Me.ComboBox4.Text = (dtSvr.Rows(0).Item("Outstring")).ToString
|
|
|
|
|
Is the combobox bound to a datasource?
Also instead of changing the text, you should try to set the selectedindex. If the text isn't already in the combobox list you can add it through Items collection (or by refreshing bindings if the list comes from a datasource).
|
|
|
|
|
This is triggered the Combobox4 prior to clicking the dropdown box and pick "Edit..." If edit is picked than the other code kicks in. Does the Combobox look bounded here?
Dim mylink As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=" + Application.StartupPath + "\Data\BW.mdb")
Dim sql As String
Dim da As OleDb.OleDbDataAdapter
Dim cmd As OleDb.OleDbCommand
Dim objCmd As New OleDb.OleDbCommand
Dim ds As New DataSet
Dim affectedRows As Integer
sql = "SELECT * FROM _servername" 'Reading the all the fields from the MDB file
da = New OleDb.OleDbDataAdapter(sql, mylink)
Dim dtSvr As New Data.DataTable("_servername")
da.Fill(dtSvr)
Me.ComboBox3.Text = dtSvr.Rows(0).Item("Instring")
Me.ComboBox4.Text = dtSvr.Rows(0).Item("Outstring")
Me.Panel2.BringToFront()
Me.ComboBox3.Items.Add("Edit...")
Me.ComboBox4.Items.Add("Edit...")

No it's not bound based on this, but if you have set the DataSource property in designer it is bound in code-behind file.
However, since you have code on several event handlers, I suggest that you put a breakpoint in every eventhandler where combobox4 is modified whether the eventhandler is for combobox4 or another object. When debugging the debugger should hit your breakpoint(s) and give you more info how/why the text is modifed. Perhaps the events are raised in different order than you expect or some code is called, which "resets" that combo.
