Hi,
I have a doubt regarding object transfer and the ease of doing it.
An object can be saved or transferred as binary, soap or xml.
An object can be serialized and transferred.
In distributed computing, was there ever an era where objects were transferred
without serialization.
If true, please mention one instance of how it was achieved.

Hi,
to transfer an object you need to serialize (marshal, deflate) it. AFAIK there is no other way of transferring objects.
The transfer itself is done via a channel (cable or air). This channel is like a queue, you have to put bit after bit into the channel to receive them at the other end. So to transfer an object through this channel you have to serialize it.
All technologies I know (RMI, RPC, CORBA ...) work like this.
Have a look at the wikipedia-article for further details about serialization:
http://en.wikipedia.org/wiki/Serialization[^]
Hope this helps you.
Regards

hello all,
i'd like to know how to implement my scenerio.
my table has a datetime field.
base on that date time, i want to send notification to the users accordingly.
for e.g due date is 30-08-2010 inside my table.
if current date is 31-08-2010, i want the system to send notification automatically.
will appreciate the answers.

You can use a windows service which will once a day look in to the table for records and send notifications if finds any.

Hi Kyi Kyi,
For this u need to use windows scheduler tasks feature so that it'll executes a task periodically everyday in a certain time of period . On the other hand create a windows application to and give it to DB connectivity and write code what you want to do. point this .exe to that scheduler task. Thats it...All Over... ...

Hi,
I need to write some application that include image analyzing.
Is there some .net libraries that can make this analyzing easy ?
for example - i need some simple object that can get bitmap stream input and return to me bitstream or raw-data.
Thanks.

AForge.NET[^] framework contains a nice and flexible image processing library.
For example this[^] excellent CodeProject article about image stitching is based on AForge.NET.

Hi All,
Easiest to explain if I show an example:
I have a DataGridView which has a column that is a combo box.
I have a dataset as the source, it has two columns: FirstName and LastName.
I want the combo box to display "LastName, FirstName", ie, I want the display member to be a combination of two columns. Is this possible? Or will I have to add a new column to my dataset "FullName" which will be the two added together?
Cheers,
Brad

Assuming that you're using Sql, how about concatenating the fields there?
SELECT [Field1] + [Field2] FROM ..

The combobox only handles a single column of displayed data.
It has a displaymember and a valuemember property for binding to the datasource.
But if you must display multicolumn in a combobox then you can concatenante your column values,
like Eddy's shown in SQL. In VB this works like:
Dim FnLn As String
Dim drRow As DataRow
For Each drRow In DataSet.Rows 'or DataSet.Tables("Table1").Rows
FnLn = drRow("Lastname") & " , " & drRow("Firstname")
cb1.Items.Add(FnLn)
Next

I ran into an issue that I cannot do a WORKAROUND with my service under the 4.0 framework.
I converted the service in IIS to 2.0, I converted the project to 3.5, and now I need to configure the service.
It is correct to assume that I must use the 3.0 wcf configuration tool instead of the 4.0 config too?

Take a look at Windows Communication Foundation (WCF). This should provide all the comms options you could possibly want (and more).

Hi Pete.
Thanks for reply me.
Can i accomplish this task without WCF, Because i am not very much aware of WCF.
Please suggest.
Shafiq

Yeah, you could, but it's also going to the be easiest route to take.
|
|
|
|
|
What is other way. can you please explain me
Thanks
Shafiq
|
|
|
|

No, I can't. There simplly isn't enough space in a forum post to cover everything WCF does and how to do it.
WCF doesn't encompass just one method of communicating. It's a suite of classes that encapsulates many methods of communication.
