ok well you can look into the System.IO.StreamReader class if you file is just plain text or you can do a search for 'Word Automation with C#' and have a look at working with MS Word, but that approach can be a bit of a pain.

What format your file in, and what data do you want to get from it, give example of input format and desired output and maybe i can help further

EDIT:

Actually i just seen your repost so my help stops here

That depends on the layout of the Excel-file and the version of Excel. I suggest you use ODBC to read Excel, or interop. We also got articles here on CodeProject that explain the reading;

* ODBC[^] approach
* Example using InterOp[^].

How to debug a remoting class

About Remoting .Net, I want to ask you how to debug a remoting object.
Suppose I have 3 projects:
+ Project RemotingService: provide Remoting class, type Library
+ Project RemotingServer: reference to RemotingService and register it to TCP Channel.
+ Project RemotingClient: this project references to RemotingService and use classes in RemotingService

They work well but I can not debug code in RemotingService project.
Could you have any ideas to solve this problem.

I've never done it personally, but I've seen #if DEBUG statements in main used to compile a service as a console app in debug mode; then it can be run and debugged just like any other program.

Creating a Standalone Application! Help plz!

Hi Guys,

I have created a small project (application). Now I want to deploy it. I dont think that I require setup for it because, the project is very small. But the problem is that, there are certain icons and small images which I have added in my form. Those are saved in the resource file, with the .resx extension.

Now when I build my application and go to - Visual Studio 2005 - Projects - MyProjectNameFolder - Bin - Release - Application.exe and copy the file .exe file and run it on another machine. It simply shows some kind of error message! Will I've to copy the entire solution? But that wont be user friendly. So how do I create a standalone application?
Please tell me the steps!

Your help will be appreciated....

Is another machine installed .net framework?

You better create a Windows Installer project with the exe file added.

It's easy to create setup, why you dont think that you require setup for it because, the project is very small?

Hi Kelvin,

Actually I was intending to create a standalone application. There are only 4 to 5 forms in my project connected to each other via creating objects of each other, and so I dont require a setup for it. I just want that the user download it and simply double-clicking the .exe file run the application, without needing any Setup.

Thanx,
Rajdeep.NET! Wink | ;)

You can't do this.

In order to run the application you need the framework.

Also simply copying the exe only works if you don't use any other references(dll's), if you do you need to copy those aswell.
But as I said without the framework it's never going to work.
Simplest way is to create a simply setup (that's only 4 screens where the user has to click next, everyone is used to that), this setup is going to check if the framework is present and install it if needed.

And we are supposed to magically figure out what your error is? Tell us the error and we may be able to help.

As a hint, you may have to copy everything in your Release folder to your target machine.

Copy all the files from the release folder under obj to a disk (you can use a USB these days), take some bluetak and apply a lump to the side of the disk you want to "stand alone" on and place it next to the computer. Whalla standonly application.

Don't be so bloody rude next time - Tom gave you a valid answer and the reasoning why you need to create an installer.

Hi again Rajdeep,

You've already been told possible cause of your problem. The target machine [shout]*MUST*[/shout] have the required framework installed. If it has, then just copying the exe (and any referenced dlls if there are any) may work. I often do this for in house apps at work as I know they all have all frameworks installed.

You can either create a SetUp project if using VisualStudio, or a Click Once deployment if using VisualStudio or C# Express. These will check if the prerequisites are met and download/install them if required.

Access to field attributes by object instance

tgoessi2-Apr-09 21:08

2-Apr-09 21:08

Hi All

How can I access to the attribute of a field by an object to whom this field references to.

I have defined:

<br />
class A<br />
{<br />
     [MyAttrib(Name="TestA";)]<br />
     private Bb testing1 = new Bb();<br />
<br />
     [MyAttrib(Name="TestB";)]<br />
     private Bb testing2 = new Bb();<br />
}<br />

Now I want to access to 'MyAttrib' within class Bb in the following way:

<br />
class Bb<br />
{<br />
     {private fields}<br />
<br />
     public string GetName()<br />
     {<br />
     return (GetMyAttrib.Name) //-> return "TestA" o "TestB", depending on the field, which references to this object-instance<br />
     }<br />
}<br />

Is there any way to do this by reflection.

Or how can the attributes assigned to the object-instances of Bb instead of assigning them to the fields?

Thank you
Tom

Try this where oClass is the object (ClassA).

			Type t = oClass.GetType();<br />
			sName = t.Name;<br />
<br />
			<br />
			PropertyInfo[] oPInfos = t.GetProperties();
