the only thing in the stack trace that is of any importance is:
"at Word.Range.set_Text(String prop)"
not really sure what that means
I only have Visual studio .net so I cannot create and old VBA project that I know of

Obviously you have Office (otherwise you couldn't even instantiate the WordApplication class), so you have VBA. VBA = "Visual Basic for Applications" and is a VB binding to the application's automation layer. Just click Tools->Macro->Visual Basic Editor.

And it won't. VB != VB.NET. It's merely the same syntax. VB (6 and older) is an automation client that uses objects defined in type libraries and implemented by COM servers. VB.NET uses the .NET BCL (base class library) and compiles to Intermediate Language (IL).
So, you copied VB.NET code into a VB IDE (Integrated Development Environment). You need to write VB which is documented if, in the IDE, you click on the Help menu (and like Contents or Index or whatever).
The basic objects will be the same, but the types not defined in the typelib (like Missing.Value) will not work - they're defined in the .NET BCL and, unless exposed to COM through a CCW, cannot be called by VB6 (which is what the VB IDE in Office and other applications uses).

Hi!
I've a Web Service and 3 different SoapExtension. In my client app., I configure the web.config to execute the 3 diferent SoapExtension.
I'm trying to throw a SoapException in the first SoapExtension and i wan´t to stop the message flow. I don´t want that the flow of the Soap Message continue.
Is that possible?

Hi!
I am writing a server/client application in which I need to transfer short text strings across a network from the server to the client. The message receiver in the client is running in its own thread, and it uses a stream reader to get the message strings from the TcpClient.
It appears that both the 'Read' and 'ReadLine' methods of the StreamReader class blocks until there is something on the stream (if it is empty when they are invoked). The problem is that not even a call to .Abort() will interrupt the Read(Line) metod (which is exactly what I want to do). Is there any way to abort a call to Read(Line)?
I have tried to use the Peek() method to determie whether or not the stream is empty. However, Peek() returns -1 even though ReadLine() returns with a string that is supposed to be there. Any thoughts on why this happens?
Does anyone no of a construct that provides a non-blocking read from a stream?

"Any thoughts on why this happens?":
MSDN states for the return value of the Peek method: "The next character to be read, or -1 if no more characters are available or the stream does not support seeking." So maybe your stream doesn't support seeking.?
"Does anyone no of a construct that provides a non-blocking read from a stream?":
Try getting the underlying stream through BaseStream property and using its asynchronous BeginRead and EndRead methods.

You'll need to use asynchronous interfaces. Use the BeginRead/EndRead, BeginWrite/EndWrite methods. Not THAT easy to do, but once you learn the asynchronous patterns in .NET, everything will be easier.
My advice: don't use TcpClient/TcpServer for anything but the simplest things, as they're too simple, and have several drawbacks, as you're starting to notice. Use the Socket class, instead, that is a bit more complex to use, but will not give you so many headaches.

Thank you all for your advice! I will switch to using sockets instead. It will take some effort, but I'm sure it's worth it! Does anyone know of a good tutorial on working with sockets?
However, I'm the sort of person who cannot let things go so easily. That Peek() does not work as I think it would  still borthers me somewhat, and I would like an explanation if there is one? I will let this go eventually, but until then I will remain confused. Anyone?
Thanks!!

Search for Sockets here on CodeProject and/or read the example given by the MSDN topics for the Socket class.

how can i clear the date time picker control from any date in it?
|
|
|
|
|
It is not possible with System.Windows.Forms.DateTimePicker, because DateTime is a ValueType and cannot be empty.
You can set dateTimePicker.CustomFormat to String.Empty, but then the user won't be able to enter a new date.
Search for "Nullable DateTime Picker" in the articles, there is a useful solution with a TextBox and a DateTimePicker.

Hi,
I have a query with regards to data sets.
I have the following declarations in C#.NET, it's just brief, so I hope it makes sense:
SqlDataAdapter adptContacts;
dsContacts.ContactsRow rowNew;
rowNew = dsContacts.Contacts.NewContactsRow();
rowNew.ContactID = GetNewContactID();
rowNew.FirstName = txtFirstName.Text;
rowNew.LastName = txtLastName.Text;
I have code that adds data to the new row, then I add the code to the data set using the following code:
dsContacts.Contacts.AddContactsRow(rowNew);
I modify the database like this:
adptContacts.Update(dsContacts);
I just want to know when adding data to the database like I did. As far as I understand it, a dataset contains data retrieved from the database. So when I do my update, does it delete the data in the table and all the data in the data set, or does it just add the new row to the table?

DataRows have a DataRowState property which defines if a datarow is modified, added or deleted. Check ur rowNew.RowState and you will se its System.Data.DataRowState.Added.
When u update the source datatable in ur underlying database, the dataadapter
method adptContacts.Update(dsContacts) will use the adapter's DeleteCommand for the Contact's table to delete any Deleted datarows, the InsertCommand for any Added datarows and the UpdateCommand for any modified rows ur datatable might have.
In ur case, ur DataTable only has one Added row, so the dataadapter will add ur row to the underlying database datatable. It wont delete anything anywhere.
In ur code, I seem to be missing where un initialize the adptContacts DataAdaper. U have to create and assign the SqlCommands to it. An easy way is to create the DataAdapter in the designer, it will create all commands by itself, unless ur querying more than one DataTable through a JOIN.

Look at the IDataAdapter.Update [^]IDataAdapter.Update documentation in MSDN. It is clearly explained.

Hi,
I am using collection to bind data to datagrid.
Dim oCars as CarCollections = New CarCollections
DataGrid1.DataSource = oCars
Everyithing work fine but there is a sorting problem.
If I do so, there is no sorting features in DataGrid. When I bind DataSet to Datagrid I can Sort data in DataGrid by clicking on columns header. DataGRid automaticly sort filled data according clicked colum.
When I bind datagrid to Collection that features is missing.
What should i do, in Collection class - CarsCollection, to have sorting features back
Thanks in advance
P.S. Sorry for bad English

IIRC, your class needs to implement IComparable for sorting work.

Can you send me a link where I can find an example or something that will help me

IComparable Interface[^]
Simply put, you just need to implement a single method, CompareTo(obj), that will compare this instance to another object, for order purposes. It must return -1 if it's smaller (or lower rank), 0 if it's equal (or the same rank), and +1 if it's bigger.

Hi,
I want to detetmin parent class
For instance there is a Cars collection with Car item.
Cars collection has some property that I need to access from Car item.
Cars collection
Property_01
Property_02
CarItem(s) (Type, Name, Year, ...)
I want to obtain the value of Property_02.
Every CarItem is already inside Cars collection and I am sure that there is way to obtain parent class.
How to do that?
Do not send answers like "You have to hold a reference to the CarsCollection in the CarItem:"
public class CarsCollection : List
{
public CarItem CreateCarItem()
{
return new CarItem(this);
}
}
I think that is something about iComponent or something similar.

Ok, we won't but there are only two ways of doing it:
1. The answer you don't want
2. Searching all the collections in your program for that specific instance.

A Component holds a reference to its container in the Container property.

I want to make a PropertyGrid control readonly on runtime.
I try to use ReadOnlyAttribute for a class or property but I don't know if I can change the value of the attribute on runtime.
Any other ideas how to make the control readonly ?

Hey people, first post for me!
I am creating a network monitoring tool that will monitor the amount of traffic going out and coming into a computer on a 10baseT connection. Was wondering if there is either any code out there that can count the number of data packets going out and coming into an ethernet connection. I've looked what feels like everywhere but still can't find anything : ( ( If anyone here has either some suggestions of stuff that already exists, or is savvy enough to put some code together quickly, could you point me in the right direction please?
I'm also going to be using .NET as part of this program, so if that's needed to do what I need then that's fine.
Cheers
Jeff
