Okay - I guess I made some mistakes with my explanation.

A reference type is passed by reference insofaras you can update the object in the method and the changes will be reflected back in the original, but you cannot assign a new object.
If you use ref you are passing a reference to a reference and you can assign a new object in the method and have that new object reflected in the calling method.

I discovered a great feature of new VS 2005 - to allow use of Classes as datasources for reports.
I created a simple class with a couple of public string fields that source my report and they show quite happily in report viewer. Great functionality.
Now, I am trying to see if I can source an Array-like type to report and get it to show the data. For example say I have a Book class, that will conain name of the Author, number of pages, price and a HashTable (or another suitable) of characteristics: size, page colors and index.
Something like:
public HashTable OtherVals
{
get{
HashTable my = new HashTable();
my.Add("size","10x15");
my.Add("PageColor", "green");
return my;
}
}
How can this be shown on report?
Rewording of this quetsion below...
the .rdls report templates, when a Class is used as its datasource - what sort of data types can it handle?
In other words - strings work great, ints etc... How about ArrayList() or HashTable() or something that will allow me pass a list of 5 items into the report and show them in a list.
Thanks a lot!

Hi,
I am converting a decimal value to string for displaying it on a label.
While converting the decimal value with two decimal places to string, 4 more zeroes are being appended to the decimal value.
eg: "45.52" is displaying as "45.520000" on label after using the following statement:
decimal d = 45.52
lblNetPrice.Text = Convert.ToString(d);
What I need to do for displaying 2 decimal values on the label other than using the substring function?
Thanks in advance.

lblNetPrice.Text = String.Format("{0:#.##}",d);
/edit: helps if you get the format right

Instead of this:-
Subrahmanyam K wrote: decimal d = 45.52
lblNetPrice.Text = Convert.ToString(d);
try this:-
decimal d = 45.52
lblNetPrice.Text = d.ToString("###,##0.00")
Cheers,
Craig

hello all,
i am working with windows control library . i am using three dll in my project. which ever dll i am using i have to make strong name for that.my problem is that i am not to able make strong name more than one. in Assemblyinfo.cs i used the following coding
[assembly: AssemblyDelaySign(false)]
[assembly: AssemblyKeyFile(@"..\..\..\filename.snk")]
[assembly: AssemblyKeyName("")]
after that use GAC to put into the assembly. for each dll i have to make .snk key pair. but when i use AssemblyKeyFile() more than once in assembleinfo.cs it gives me error duplicate assembleykeyfile() file attribute. how could i use more than one dll in our project.

The AssemblyKeyFile attribute is used to *build* a strong named assembly, you don't need it for referring to a strong named assembly.
So you need to have the attribute in the AssemblyInfo.cs file of each of the DLL projects, that's it.

Senthil

What exactly do you want help with... your question is akin to asking "I want to build a website, how do I do it?"

You need to at least TRY something yourself, when you hit a specific problem feel free to post a question remembering to include any code and eror messages.
Nobody could answer "How to build an XML Editor" in a single post!  If you just want an example there will be many available by doing a search on google.

Hi All
I'm not completely sure whether this is the best place for this question but someone out there may be able to provide suggestions. I am in the process of designing an Inventory system which holds details about object within our department. This can include books, software, logbooks etc. The aim is that it will allow loans as well as maintain project information about logbooks, staff information etc.
Now I originally designed a database, creating an E-R diagram to ascertain the tables etc in which to store the information. The intention was then to produce a C# front end to display the information and control access etc. Now my question is this.... Do I need to go through the design process (Analyis, design etc) in UML for the C# part of the application or do I simply gear the front-end to the structure of the database? If I do serperate analysis and design then the models produced for the C# part of the application add various classes etc that are not accounted for in the database.
What is the general approach to this sort of application? How do people go about designing it? Say the database has a table for books and one for software... I find that the analysis for a C# application provides a generalisation such as InventoryItem... I hope this makes sense.... What I really want to know is how people go about designing this sort of application.
Any help or guidance would be gratefully appreciated
Cheers
Jamie

Hi Friends,
I am developing scheduler application using C#. For displaying all
schedule information i am using ListView control. Based on the status
of the schedule, i have displayed the schedule information in the list
view as seperate colors.
I have faced the problem with deselecting the list view item. For
example, if i select the first row,(with blue color) of the list view
and deactivate the selected item by clicking the row which has no
elements, the color for the first row not appear, it appear as white
color. I just apply refresh method also. but i didn't get the actual
color at the row.
Please help me to solve this issue.
Regards,
Prakash.

The way of presentation is not clear. Try to explain clean and concise.
Check the selection property of list view. Set the value of MultiSelect property to True.

Imagine DataGrid contains three columns of its DataSource And another columns of DataSource have been to fill with two TextBoxes . So I want to fill them when the new row in the grid is filling .
The following code to do this operation :
private void dataGrid1_CurrentCellChanged(object sender, System.EventArgs e)
{
try
{
int colNum;
int rowNum;
colNum = dataGrid1.CurrentCell.ColumnNumber;
rowNum = dataGrid1.CurrentCell.RowNumber;
//fill 2 columns of dataset
int cod1,cod2;
cod1=Int32 .Parse (textBox2.Text );
dataSet31 .factor .NewRow ();
* dataSet31 .factor [rowNum ].proje_code=cod1;
cod2=Int32 .Parse (textBox1.Text );
dataSet31 .factor [rowNum ].hazineh_code=cod2;
}
catch(Exception ex)
{
MessageBox .Show (ex.Message );
}
}
But in execution time when I click on forth row and it arrives to the marked line with star then this error message appears :
there is no row in position 4
. I want to Insert the new information of DataGrid to my DataSet that has 5 columns . you khow that my DataGrid has 3columns of its DataSource(DataSet)
. 2 TextBoxes fill the 2columns of DataSet . this 2 columns are the 2 field of primary key
. in execution time when I fill a row of DataGrid this error appeares :
. column ' proje_code' does not allow null
Thanks
