Hi,
I can de/serialize objects of a class called Bookings.cs
Had a System.Drawing.Rectangle obj with an [XmlIgnore] in this class
and it ignored it 
Later on I decided not to have rectangles displayed in
my windows form because I had to set event handling to them.
So I thought that I could use a flatted Button instead that resembles
a rectangle but also has event methods.
But I wanted a custom control so I extended the Button class.
These MyButton objects are created dynamically and I also declared this MyButton
obj with the [XmlIgnore], just replacing the System.Drawing.Rectangle obj with
MyButton myBut and instantiated it in the constructor of Booking.cs
During run-time i get a reflection error trying to create the XmlSerializer object with typeof(Booking[]) ??
Have googled it all day but cannot seem to understand the problem?
Is it because it is a inherited class this error shows up?
Seeking knowledge, Daniel...

I am trying to query an AD residing on a different server and came across a snippet. The following line caught my attention:
DirectoryEntry objEntry = new DirectoryEntry("LDAP://DCName/OU=testOU,DC=x,DC=y,DC=z,DC=COM","username","password",AuthenticationTypes.Secure);
Is there a way around hard coding the "username" and "password"? The last three parameters, are they even necessary for creating the DirectoryEntry instance?
Thanks

The only thing that is 'required' is the server path. The others would be optional parameters as far as I know. This is how I'm querying our AD server (keep in mind however if you're trying to modify anything in the entry, then it will require proper permissions to do so). I needed to query AD based on the samAccountName of a user. I am in NO way an expert, but this worked for me:
string uName;
uName = Environment.UserName;
DirectoryEntry entry = new DirectoryEntry("LDAP://SERVERNAME.SOMEPLACE.COM");
DirectorySearcher mySearcher = new DirectorySearcher(entry);
mySearcher.Filter = ("(samAccountName= " + uName + ")");
Hope that helps for you. Best of luck.

Thanks a lot for your response Chris, but suppose you are running your application using localhost while the AD hierarchy is set up in a remote machine in the network under a different domain, in that case would the additional parameters help? My querying AD using .NET concepts are a bit flaky and would really like to understand more.
Thanks...

Hmm... Well, ours is all on one domain. I wouldn't think it would require much different because of the domain controller communication. As long as it was an authenticated client on the domain (duh..  ..), I would think that it wouldn't matter which domain it was trying to communicate with. I myself am a bit flaky also, and as I said, it worked for us. You might try a little google grease with the extra knowledge you've presented to me, such as "DirectoryEntry use across domains" or something. I wish I could help more (and wish I knew more myself) so I could be of better help. Best of luck.

The kind of project that gets the business moving forward. Projects are not prioritised highly unless the business needs it (or rather the business "thinks" it needs it). In my experience companies often mis-prioritise projects then wonder what the brown stuff that's just got sprayed all over the walls is when the s**t hit the fan. (But you probably don't want to say that in an interview)

Hi, can anybody write steps to build an undo and redo functionality in C#. I checked couple of articles but they are all confusing.
I have a panel class that holds different items on panel. I want to store each panel in an arraylist/stack. So if user click on undo then just display that panel
Thanks

You basically have to implement the Memento design pattern.

I wanted to bind a collect to a DataGridView, but the objects in the collection are collections themselves. Ideally, I'd like the objects in the later collection to be displayed as rows in the table and I thought I might be able to do that using the ITypedList interface and a custom PropertyDescriptor class. I came up with something like this for my GetItemProperties implementation:
public PropertyDescriptorCollection GetItemProperties(PropertyDescriptor[] listAccessors)
{
PropertyDescriptor[] properties = new PropertyDescriptor[myCollection.Count];
for (int i = 0; i < myCollection.Count; i++)
{
properties[i] = new MyPropertyDescriptor(i.ToString(), i);
}
return new PropertyDescriptorCollection(properties);
}
MyPropertyDescriptor uses the index in the collection as a name for the property and also stores the index so I can recall the value.
Now to add a column to the collection in the DataGridView I do this:
design.Channels[0].Add(0);
DataGridViewTextBoxColumn dgvtbc = new DataGridViewTextBoxColumn();
dgvtbc.DataPropertyName = "0";
dgvtbc.HeaderText = "0";
dgvtbc.Name = "0";
dgvLevels.Columns.Add(dgvtbc);
This adds the column, but it doesn't appear to actually be bound to the data source because if I can the value in column 0, the corresponding item in the collection isn't changing. Does anybody have any idea if this can be made to work? Am I barking up the wrong tree?
Thanks

Hello,
I have an HtmlFile that is read into a string. I make some modificatons to the string, and now I want to convert a string to an HtmlDocument object.
Is there a way to go about it?
Thank you very much.

Hi Zaboboa,
This should do the trick:
Dim text as string = "any html"
Dim newDoc As New HtmlDocument
newDoc.LoadHtml(text)
Kind Regards

.Net framework doesn't provide a way to get an AppDomain based on its friendly name. One can get the current thread's AppDomain, but I would like to get an AppDomain based on just its friendly name. Has somebody tried it?
Any help is welcome.

Currently, I can easily drag items between DGV's. If I select multiple items by holding the CTRL button while I click, and on the last item, I initiate the drag without letting up the mouse, I am able to drag multiple items.
However, if I select the last item, let up the mouse button, and then put it back down again to grab the items and drag them, the DGV selects the item that was under the mouse click. I realize this is the expected behavior; does anyone know a way to override it so that my items remain selected?
Now, I have a workaround that involves keeping track of the selected items myself, and if the mouse goes up and backdown and a drag begins, to re-select those items. But it's a little bit messy and I would really like another way to do it.
Any thoughts?

This is a 2005 project under 2.0
I am using Enterprise Library 2006
I am making a Select Call which returns an IDataReader.
I have checked the object after being populated and it seems to contain the information I need.
I go to convert it to a DataSet and it only shows the last item.
here is my Convert to DataSet code, I've tried numerous of examples found on the web, each one only returns the last record:
<br />
public static DataSet ConvertDataReadertoDataSet(IDataReader reader)<br />
{<br />
DataSet ds = new DataSet();<br />
DataTable schema;<br />
DataTable data;<br />
int i = 0;<br />
DataRow dr;<br />
DataColumn dc;<br />
string columnName;<br />
bool dun = false;<br />
data = new DataTable();<br />
schema = reader.GetSchemaTable();<br />
<br />
do<br />
{<br />
if (schema != null)<br />
{<br />
for (i = 0; i <= schema.Rows.Count - 1; i++)<br />
{<br />
dr = schema.Rows[i];<br />
columnName = dr["ColumnName"].ToString();<br />
if (data.Columns.Contains(columnName))<br />
{<br />
columnName = columnName + "_" + i.ToString();<br />
}<br />
if (columnName == "ID")<br />
{<br />
System.Type typeInt32 = System.Type.GetType("System.Int32");<br />
<br />
dc = new DataColumn(columnName, typeInt32);<br />
}<br />
else<br />
{<br />
System.Type typeString = System.Type.GetType("System.String");<br />
<br />
dc = new DataColumn(columnName, typeString);<br />
}<br />
<br />
<br />
data.Columns.Add(dc);<br />
}<br />
<br />
<br />
ds.Tables.Add(data);<br />
<br />
while (reader.Read())<br />
{<br />
dr = data.NewRow();<br />
for (i = 0; i <= reader.FieldCount - 1; i++)<br />
{<br />
dr[i] = reader.GetValue(i);<br />
}<br />
data.Rows.Add(dr);<br />
}<br />
}<br />
else<br />
{<br />
dc = new DataColumn("RowsAffected");<br />
data.Columns.Add(dc);<br />
ds.Tables.Add(data);<br />
dr = data.NewRow();<br />
dr[0] = reader.RecordsAffected;<br />
data.Rows.Add(dr);<br />
}<br />
<br />
}while (reader.NextResult());<br />
<br />
reader.Close();<br />
<br />
return ds;<br />
}
I f10'd through it and it seems to only be doing the 'do/while' once, the NextResult() is not going to the last record because it seems like its already at the last record.
Any suggestions or examples of another way of doing it would be great.
it needs to return a DataSet with multiple records.
Thanks

NextResult moves the data reader on to the next result set, not the next row. Read moves the reader to the next row until it gets to the last row in the current result set.

Thank you for the reply. I found a way to work with the IDataReader that I am getting back so there is no need to convert it.
Appreciate the time on this though, enjoy your day.

I would like to create different versions of a program, but I'm not sure how to achieve that in VS2005. I've looked at configurations and conditional compilation, but I haven't found anything that works yet.
Here's what I would like to do:
I need three versions of a program:
Version 1
=========
* Contains a user interface for analysing data
* Contains code and a user control for talking
to an electric motor, also contains a dll
that does the low level communication with
the electric motor.
This version would be installed on computers that have the electric motor attached.
Version 2
=========
* Contains only the user interface for analysing
data
This version would be installed on computers that don't have the electric motor installed. They would therefore also not have the dll and not need the user control for talking to the motor.
Version 3
=========
* Contains a simplified user interface for displaying results of the analysis.
What's the best way to achieve having these separate versions?
Thanks for your help.

Why not have several project in the same solution. Each sharing the source code for the items each version needs.
|
|
|
|
|
Thanks for your answer.
The reason, why I would like to avoid it is this: When I add a new source file to one of the projects, I have to add it to all projects, in case it is needed there. That is fine with a small project, but this one will over time get rather large and I want to keep maintenance of different versions to a minimum.

Conditional compilation is for small changes between different versions of the same assembly - e.g. DEBUG vs. RELEASE or excluding some features in a compact framework build.
You should create separate libraries for each module of your program and create three .exe files that use the libraries required for that version.
