.NET (Core and Framework)

4-Jul-03 5:18

I have released v1.2 of my Code Store[^] add-in for VS.NET, which does work (for the most part). Now I want to move on and add a better user interface and proper handling of settings before adding some more useful functionality.

I started by using ISerializable to serialize the settings, but had problems, so I switched to the Microsoft Configuration Management Application Block (CMAB[^]), but now I have hit yet further problems with this, that I have posted a question about on the microsoft.public.dotnet.distributed_apps newsgroup.

What I really need is someone (or some people) who know what they're doing to come in and fix these intial problems so that I can get on with the serious business of adding functionality. If you are interested and think you can help, then please wander over to GotDotNet Workspaces[^] and dowmload the code.

There are also issues relating to add-in registration and the setup of the menu item, etc. that would also be good to fix asap.

Now that sounds nice Smile | :)

Something that has been missing for while!

What seems to be the problem though? Also, can you provide a single file "solution" (no pun intended) to download, or specify the "bad" files in question?

OK, so I find your options.cs file Smile | :)

But where are you using the CMAB?

AFAIKC, this is the implemention (2 ways):

...
ConfigurationManager c = ConfigurationManager.Items;
...
c["mysetting"] = Blah.Blah.Foo;
c["font"] = WebDongs;
...

// Write a specific data element to the default configuration section

ConfigurationManager.Items["connection_string"] = "Some String";

// Read a specific data element from the default configuration section

string conString = (string)ConfigurationManager.Items["connection_string"];

The Read/Write methods are "extras".

Hope this helps Smile | :)

Just to check if everything was going wrong I added a call to Initialise in the Options constructor: ConfigurationManagaer.Initialise(). This is the first place that the exception is thrown.

However, the call to Initialise should not be necessary, so the first place I should be calling CMAB is in the Options.LoadOptions call: this.configData = ConfigurationManager.Read();

Did you add the :

<section name="applicationConfigurationManagement" type="Microsoft.ApplicationBlocks.ConfigurationManagement.ConfigurationManagerSectionHandler,Microsoft.ApplicationBlocks.ConfigurationManagement, Version=1.0.0.0,Culture=neutral,PublicKeyToken=null" />

Section to your appfile.config file?

By all means join as a member of the GotDotNet workspace project. I'll let you in and check-in whatever files you think need changing.

Hi all,
I spent almost one day to find out why do i receive unhandled exception when trying to select multiple rows in a form's DataGrid. I will get the error if I put a DataGrid to a form and choose any unexpandable data source (for e.g. an ArrayList), which produces readonly DataGrid by default. If I start to select the last 2 rows in my readonly DataGrid with the keyboard (<shift>+<crsr down="">) and keep my fingers on the keyboard for a while (trying to select the unexisting rows), then pressing a <shift>+<crsr up=""> leads to crash.
If the DataGrid is not read only, then working fine. (only the DataGridTableStyle can be readonly to avoid the exception)
I could not believe my eyes, so I downloaded an MS example, called "datagridcustomization.exe" from http://download.microsoft.com/download/c/9/8/c985dbd0-2ba9-4c75-86ba-a108e64b0970/datagridcustomization.exe

but this produced something new, which is also strange.
just unpack the example and run the program found under the /bin directory and simply press the <crsr down=""> key until you reach the end of the datagrid Confused | :confused:

since i just started to learn .Net framework, i do not know if this kind of component behavior is normal or not? Smile | :)

Is there any global exception handling possibility to handle such exceptions?

thanks

Problems upgrading to from 1.0 -> 1.1

Ok guys, I've been wrestling with this for a while now and am not getting anywhere. I just can't get MS Visual Studio to recognize my 1.1 .NET SDK update. I'm on a win 2K machine and have VS .NET professional installed (which installs the 1.0 SDK be default).

When I try installing the 1.1 SDK over the 1.0, VS .NET doesn't recognize the update. It says (under help->About Microsoft Development Environment) that I have the 1.0 framework installed. I get no errors when installing the 1.1 SDK, and am installing the 1.1 runtimes first, before the sdk.

Ive tried uninstalling 1.0 SDK, and then reinstalling 1.1. When I did this MS Visual Studio gives me errors and says I need to reinstall VS.

Any ideas? At the very least can someone give me the order in which I should install/uninstall everything? I may end up just moving to a different/fresh machine and starting over.

Thanks for any help

Are you using Visual Studio 2002? Visual Studio 2002 only targets NET 1.0 .You can not use the .NET 1.1 from within Visual Studio 2002.

To build a .NET 1.1 App you have two options:

1. Use Visual Studio to write and organize your files and then use the command line compiler on the 1.1 SDK folder to build your app (but remember that NET 1.1 introduces some code-breaking changes to NET 1.0)

2. Upgrade to Visual Studio 2003

I heard it was $29 for all non academic versions... and dont worry, I have not seen any breaking between compiling for each other, then again I dont touch a DB if u even paid me.

Dear all experts Rose | [Rose]

,

Hi, this is my first message on codeproject. I am very new to .NET programming. I like to know how to duplicate an ArrayList.

--Can I write this?:
System.Collections.ArrayList ListCopy=ListOriginal.Clone();
--or--
System.Collections.ArrayList ListCopy=new System.Collections.ArrayList();
ListCopy=ListOriginal.Clone();
--or--
System.Collections.ArrayList ListCopy=ListOriginal.ToArray();
--or--
System.Collections.ArrayList ListCopy=new System.Collections.ArrayList();
ListCopy=ListOriginal.ToArray();

or any other method ? Please give me advise.
Thanks you very much. Big Grin | :-D

Regards,
Jasper Lai.

These two will give you an Array not an ArrayList.

Correction: This does return an ArrayList NOT an Array.

From the SSCLI:

public virtual Object Clone()
{
    ArrayList la = new ArrayList(_size);
    la._size = _size;
    la._version = _version;
    Array.Copy(_items, 0, la._items, 0, _size);
    return la;
}
