This will explain how to get unique key. And you can use it with algorithm to get serial key. If you do not wan't to protect then my suggestion is a Demo mode. You have limited functions, and when someone bought it, they get to download full version.
Any approach you take, it will be pirated.

Hi Group members,
I have a problme here...
I have an NT service which i am using as an asynchronous scheduled job in a remote server.
I wish to convert it into a webservice, to make it synchronous, and expose it to the clients, with an ease...
Can some one suggest what would be the right approach to start with??
The NT service is written in the .NET platform.
I think it's a good challenge open for the group...

Depending on how your original service was written, you may be able to reuse parts of the code. But, as a general rule, you'll be rewriting the thing from scratch.
But, since we know nothing of what your existing service is doing, we can't really make any recommendations, or even if a web service is a viable option for what you want to do.

well, it is written earlier as a VB.NET scheduled job... then we made it as a .NET NT service...
When u say some part can be reused, i believe that's about the logic part...
we mght have to change the ways it is triggered and the way it can be invoked... am i right or going wrong?
Well, why webservice, as it's better in the ways that it can be exposed for a larger consuming services, and on gets it can invoke, only when required... unlike the scheduled job...

Absolutely right. You will have to change the way it's triggered. The only way to trigger a method on a web service is to call it from a client over HTTP. This will require you to write an app that will call the web service and probably launch that as part of a scheduled job. Oh, wait. You just ended up back at where you started from making all of this a moot point.
Granted, you get the ability to pass parameters to the web service method call and call it any time you want. But, you have to understand how web services work, security implications and how they relate to what your service is doing, the accounts and limitations that the web service runs under, impersonation may be required, depending on your requirements, and in that case, user authentication issues, ...

Thanks Dave,
for taking time and helping me in analyzing this issue.
Let me do a prototype of what i want through what i know, and have learnt from u and other online resources.
I would need your help in future too...
about your concern, as it's going to be an internal application, not exposed to www, we might not have to worry about security implications...
But, yes, other doubts and concerns are valid and should be thought upon...
Thanks,

Hello all and let me explain my problem briefly in Windows Forms application.
If any of you read Julia Lerman`s book, i am basicly implementing the techniques that are explained there but one thing i couldn`t solve. To make it simple i have two tables with one to many relationship, like customer and address. I add the customer to the datasource and change the address navigation property to combobox.
I drag name, surname and adress to the Forms. This is how i do databinding
CustomerEntities context = new CustomerEntities();
List<adress> myadresses = context.addresses.ToList();
CustomerBindingSource.DataSource = context.customers.Execute(System.Data.Objects.MergeOption.AppendOnly);
AddressBindingSource.DataSource = myaddresses;
Now as the book says i set the datasource of the addreess combobox to AddressBindingSource in UI then set displaymember, value and selectedItem.
Everything works fine except that display member of the combobox doesn`t display porperly. It diplays as MyAppName.Address, meaning object itself..What am i missing please help me

Not sure I fully understood your needs. But try to override the ToString() method in order to select what's you want to display.
|
|
|
|

Thanks, i override the tostring method of the entity object to get the work done..When i use listbox nothing is needed to display correctly but with texbox this is needed i guess, thanks again

I have one application that we lost the source code to that I'm rewriting and another app I'm writing to help a business partner that I started yesterday.
I created a class project, removed the Class1 library, then added the Linq to Sql class type.
So far so good.
I added my tables and queries and rebuilt the application to start coding.
But when I start my normal process using (MasterContext context = new MasterContext()){} I keep getting the error that the context cannot be converted to IDisposable. WTF???!!!!
I've done everything I can think of but I keep getting this error. Also if I get rid of the using a write a select, the variable used in the from statement refuses to expand. Now I know that is usually a sign that I've screwed something up, but I cannot see what it could possibly be.
Any input would be greatly appreciated.
Michael

Does MasterContext implement IDisposable? If not you can't have it in a using
|
|
|
|
|
You must not know anything about Linq to Sql. MasterContext in a Linq to Sql class inherits DataContext which implements IDisposable. Also the documentation for Linq to Sql has almost the first line stating you should always use using() when creating a DataContext.
|
|
|
|
|
You're right, I don't know anything about Linq to SQL 
|
|
|
|
|
System.Data.Linq.DataContext implements IDisposable, so MasterContext will too if it subclasses System.Data.Linq.DataContext. Check your inheritance hierarchy (not forgetting partial class files). It is also possible that something has gone wrong in auto-generation, if all else fails, I suggest is a restart (which fixes a surprising number of the odder problems).Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.

My application behaves unpredictably as I turn on the 'Group similar taskbar buttons' option in the Taskbar properties.
Strangely, the problem occurs only on some computers.
It is as follows:
I enable the Group similar taskbar buttons option in the Taskbar properties. As the taskbar buttons begin to get too small Windows automatically groups buttons so that all of the open buttons from the application are grouped into one taskbar button. This works fine.
The icon of the groupped button is Application's default resource icon which is also OK.
The problem is that the caption of the groupped button is set to the AssemblyName not the AssemblyTitle defined in the AssemblyInfo.cs file.
As I mentioned this problem occurs only under some conditions. I can not determine them.
For example the feature works fine as I run the application from local disk while it does not work as I run the application from network disk (same machine, same application).
Best regards,
David

I doubt this will really help you much...but are you aware of the fact that .NET applications running from a network share are treated as security risks? Maybe that ties into your issue somehow.

Hi,
I'm writing a UserControl that has similar functionality to the ListView but I'm writing it from scratch, it has columns and rows of type List<t>;
Everything is generally fine with the project its moving along except when I add items to columns or rows at design time, the IDE seems to be doing something odd when generating code in InitializeComponent().
For instance;
private void InitializeComponent()<br />
{<br />
BigView.Column column1 = new BigView.Column();<br />
this.bigViewer1 = new BigView.BigViewer();<br />
column1.Value = "Key";<br />
column1.Width = 253;<br />
new BigView.ColList().Add(column1);<br />
}
Every time I re-compile the project the columns are not reloaded in the designer, because the code above never really assosciates the column with my user control. I've tried lots of combination of attributes but nothing solves my problem.
This is what I'd expect the code should look like;
private void InitializeComponent()<br />
{<br />
BigView.Column column1 = new BigView.Column();<br />
this.bigViewer1 = new BigView.BigViewer();<br />
column1.Value = "Key";<br />
column1.Width = 253;<br />
this.bigViewer1.Columns.Add(column1);<br />
}
Does anyone know why the designer would do this? Why it creates a column but never adds it to my Columns property?
The columns property is a List<column>. The same thing happens with my rows property which is a List<row>.

I've solved this. I tried defining several attributes for the property and built the project but nothing seemed to change. After reading this article on [MSDN], section 'Generation of Nested Objects'; "mark a property with DesignerSerializationVisiblity.Content to indicate the code generator should "walk in" to this property and generate code for it" I had set this a while ago but found out I had to re-start visual studio for the changes to take effect?? not sure why I need to restart VS tho, but once I did it worked.
Does anyone know why I have to re-start VS to see changes in the UserControl? I'd have thought a simple 'rebuild' would have refreshed the loaded dll.

Hi i'm using this

<DesignerSerializationVisibility(DesignerSerializationVisibility.Content), MergableProperty(True)> _
Public ReadOnly Property DatabaseFields() As List(Of VerticeBindingField)

Return Me._databasefields
End Get
End Property

This is probably a newbie question so bear with me as I am new to C#/OOL
I'm currently developing a client/server system where what I would like to happen is that the server reads the eventlog whenever the eventlog is updated, stores this info and then updates the console on the client with the new information. So far I've got the eventlog reading working ok but can't work out how to get the server to call a method on the client to update the client console.
I currently have a method on the client (displayInfo()) which if I run every 10 seconds does what I want but I would rather call this from the server as and when the eventlog is updated. I also currently have at least some Remoting functionality through a ClassLibrary as the client needs to read the data from the server.
Additionally - With regards to remoting is a communications channel a 2 way thing i.e once a channel is established can it be used to process data in both directions or can it only be used by a client to retrieve data from a server?
Thanks for your time

As the server will have no way of knowing what clients are available you will need some mechanism to register the clients with the server. However, depending on your usage and where the clients will reside it may be better to poll the server occasionally. Alternatively, the server could place information is a database which the clients access to display it. Again depending on several factors you may be able to use SQL Dependency to have the client refresh it's view.

That makes sense and makes it far less appealing so based on that I'll switch to periodic polling from the client as it really isn't worth the effort at this point
Thanks for your time
