Hello,
I have an ASP.NET application that includes an administrative site built in VB.NET web forms, and web services that are using in conjunction with a Macromedia Flash fromt end. The web services are written in C#. There is also a class library written in C# that is used by the Administrative web forms.
The application runs as expected, however, when I went to deply the application, the production server at the client site, was running version 1.0 of the framework. They allowed me to install it on another server, but there are issues within their internal network that are preventing this from working properly and their security policies wil not allow me to make the changes necessary to run the application.
The client has come back and they are willing to pay for a re-write that will run on version 1.0 of the framework.
I am running visual studio 2003. I am looking for a tool that will do the conversion, or if it will be possible for me to make the needed changes or re-write the app in VS 2003.
I am the only .net developer for my company and I just started there a few months ago, so there is no older version of visual studio, so in an effort to make this project profitable, I need to convert this if at all possible with existing software or a reasonably priced conversion tool.
Any help would be greatly appreciated. Thanks.

Depending on whether or not your app uses functionality that was added or changed since v1.0 of the .NET framework, this can be as easy as directing your executable to use v1.0 or just recompiling the app under v1.0.

Here's[^] some information on the differences between framework versions as well as how to redirect your app to use the appropriate version.

Hi,

i am using .NET Compact Framework with Visual Studio C# .NET 2003 for a little PocketPC application.
I want to use the Clipboard but it seems to be not available in .NET CF.

Also i cannot find the method .Copy() within System.Windows.Forms.TextBox.

Does anybody has an idea?

Thanks in advance.

You need to register the dll for COM use with the regasm.exe tool.

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

Dim dataGrid As DataGrid = source

How to determine parent class

11-Nov-04 1:17

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"

I think that is something about iComponent or something similar.

Why not? As far as I can see it is the most obvious solution.

Tancev Sasa wrote:

Sure, the IComponent interface (note that it is an interface and you are going to have to create the implementation yourself), has a property called Site, which returns an ISite (another interface, meaning you will have to implement it yourself again) which manages the relationship between an IContainer (which you have to implement on your collection) and and IComponent.

And, guess what you are going to have to do in your eventual implementation for the IComponent, IContainer and ISite interfaces....

Anyone want to help start a movement...

I want Microsoft to alter the .net framework in such a way as to provide at least minimal protection for software developer's intellectual property and or licensing.

They designed just about the entire .net framework from the ground up to provide protection for users and didn't think to spend even 2 seconds worrying about the developers they are trying to convince to use it.

I know some of you are going to say "Well what can they do, it's an intermediate language" I know that, but the point is that *they* wrote it and they have many big brains on staff that could have considered the developers and *their* rights but I don't think they did for even a second.

The way it is now, every .net app is an "open source" app, whether you wanted it to be or not. You have essentially zero protection of your software and their only apparent solution is obfuscation which still makes cracking a license scheme a matter of a day instead of minutes.

At least in the Win32 days a certain level of knowledge was required to crack a skillfully written license protection scheme. You could be confident if you were compromised it was by experts, not by any moron with a two week knowledge of .net and a freely downloaded utility from the internet.

(No, I'm not ranting because we were cracked, I'm ranting in anticipation of having to devise some sort of license scheme for a very large .net application)

Microsoft have the advantage of course of controlling windows itself so if they release .net based apps in future they can probably work some protection for them right into the O.S. if need be. I'll be curious to see what they do.

Anyone with me?
Anyone know where to more effectively post this rant?
Am I dreaming that anything will ever get done?

Doesn't .NET already have some licensing framework?

For components it has some rudimentary bits you have to fill in. In terms of license protection it has absolutely nothing of consequence.

[Flags()] and Property window

Palladino10-Nov-04 8:03

Palladino

10-Nov-04 8:03

Perhaps this is a stupid question, but I sought plenty and I didn't get to find. Imagine that there is an enumeration as the one that proceeds:

[Flags ()]  
public enum AnyOptions  
{  
	Option1 = 1,  
	Option2 = 2,  
	Option3 = 4  
}

Now there is a property in a specialization of System.Windows.Forms.TextBox

public class MyCustomTextBox: System.Windows.Forms.TextBox  
{  
	private AnyOptions options = AnyOptions.Option1;  
  
	[Browsable(true)] //this is the point!!  
	public AnyOptions Options  
	{  
		get {return this.options;}  
		set {this.options = value;}  
	}  
}

Question:

As I do for this property to have a "normal" behavior in the properties window. I imagine that it is some editor type, I don´t know.

Thanks in advance,

Hi,

i'm a .NET newbie and hope someone can help me. I try to build something like an applet (Java) with C# and .NET. I've been told this can be done by a windows forms control assembly embedded in a html page via the well known <object> tag. Indeed,
everything works fine except the control's database access to a local database. Here i get the exception "SQLClientPermission denied". I'm sure the problem lies in the CLR access policies for the code of the embedded control (coming from the intranet zone). Can anyone tell me how to grant this SQLClientPermission to the code of my control?

Thanks for your help,
