I assume because that's the one that doesn't have the attribute. Hard to say, I don't see your XML, and you don't say if you did what I told you to do to work out the exact problem.

[newbie] [error] must declare a body because it is not marked abstract, extern, or partial

I'm trying out remote debugging from a WinXP Pro machine to a Win 2003 Server machine (where the source code is deployed).

When I try to compile from Visual Studio 2008, the following error is displayed:
Error 1 'CaseTrak.Activities.StatusUpdater.CTSetCaseReviewStatus(string, int)' must declare a body because it is not marked abstract, extern, or partial z:\Projects\CaseTrak.Activities\CaseTrak.Activities\StatusUpdater.cs 37 21

<code>
public bool CTSetCaseReviewStatus(string sCaseID, int iStatus)   //{ //get; }
<code>
</code></code>

Resolution (http://msdn.microsoft.com/en-us/library/bb397743.aspx[^])suggests to me that get and set methods have to be set for the variable type, however, it does not seem to fit within the context.

Any ideas?

// cs0840.cs
// Compile with /target:library
using System;
class Test
{
public int myProp { get; } // CS0840

// to create a read-only property
// try the following line instead
public int myProp2 { get; private set; }

}

            return ActivityExecutionStatus.Closed;
        }

        public bool CTSetCaseReviewStatus(string sCaseID, int iStatus);

	}

Hi As you know a class can have fields,methods,properties and events.In general ,methods are behaviors and fields are attributes of a class.(Properties are some special methods to control accessing to the fields according to the encapsulation rule) therefore if there's a behavior (method or property) it should be implemented (or as the exception says should have a body using brackets) unless it's either an abstract method in an abstract class that it's inheritor should implement it and thus it should not have a body or an external method (a placeholder for a windows API method)
The problem here is that you have a CTSetCaseReviewStatus method that has no body.You can change it like this:

public bool CTSetCaseReviewStatus(string sCaseID, int iStatus)
{
//Do something and return its result
}

If there's no method for this, you can iterate over the Keys and use those to copy the values in.

If you use .NET 3.5 then you can use the Union method:

Dictionary<int,> dicA = new Dictionary<int,>();
dicA.Add(1, 10);
dicA.Add(2, 20);
dicA.Add(3, 30);

Dictionary<int,> dicB = new Dictionary<int,>();
dicB.Add(3, 35);
dicB.Add(4, 40);
dicB.Add(5, 50);

var newDic = dicA.Union(dicB);

Hi,
Unfortunately I couldn't get you. What do you mean by Run It? Or Reopen It?
When you create a new instance of a Control (User Controls too) its properties got their default values (I hope I could tell it right).

I died as a mineral and became a plant,
I died as plant and rose to animal,
I died as animal and I was Man.
Why should I fear? When was I less by dying?

Ummm... So you set the ShowThing value to false but when you run your application they're visible?
Maybe you changed some values in PropertyBinding or DataBinding. Make sure their values are set to none.
I have a UC like you. It has a property named TextMultiLine, here:

public partial class LabeledTextBox : UserControl
{
    public bool TextMultiLine
    {
        get { return txtText.Multiline; }
        set { txtText.Multiline = value; }
    }
}

And I have no problem with it:

public partial class frmMain : Form
{
    public frmMain()
    {
        InitializeComponent();
        LabeldTextBox ltxt = new LabeledTextBox();
        
        ltxt.TextMultiLine = true; // And it works in runtime and everywhere else
    }
}

I think your problem is in somewhere else. I hope you can find it Smile | :)

hi ,
i have this problem,
i have a grid contains project combo box and projectStage combo,when i select the project from first combo it will filter the second combo values,
i got it but when i m selecting the project for the next row it filter all second combo values even in the first row, here is my code

private void FrmMain_Load(object sender, EventArgs e)
{
EMS.Timesheet timesheet = new WindowsApplication1.EMS.Timesheet();
dsInitialData = timesheet.GetInitialData(UserProfile.EmployeeId);

bscProject.DataSource = dsInitialData.Tables["Projects"];
dgvTimeAttProject.DataSource = bscProject;
dgvTimeAttProject.DisplayMember = "ProjectRef";
dgvTimeAttProject.ValueMember = "ProjectId";

bscStage.DataSource = dsInitialData.Tables["Stages"]; ;
//bscStage.Filter = "ProjectTypeId=-1";
dgvTimeAttStage.DataSource = bscStage;
dgvTimeAttStage.DisplayMember = "StageName";
dgvTimeAttStage.ValueMember = "ProjectStageId";
}

private void dgvTimeAtt_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
try
{
if (e.RowIndex == -1)
return;

if (dgvTimeAttProject.Index == e.ColumnIndex)
{
int ProjectId = (int)dgvTimeAtt.Rows[e.RowIndex].Cells[dgvTimeAttProject.Index].Value;
int projectTypeId = GetProjectType(ProjectId);
bscStage.Filter = "ProjectTypeId=" + projectTypeId.ToString();
bscActivity.Filter = "ProjectTypeId= " + projectTypeId.ToString();

//dgvTimeAttStage.DataSource = dsInitialData.Tables["Stages"].Select("ProjectTypeId=" + projectTypeId.ToString());
//dgvTimeAttActivity.DataSource = dsInitialData.Tables["Activities"].Select("ProjectTypeId= " + projectTypeId.ToString());
}
}

catch (Exception ex) { throw ex; }

}

so how can i overcome this problem?

i will ask it in other words,
if i have grid with tow DataGridViewComboBoxColumn first one for contries and second one for cities , when the user select a country the city combo will have the all cities in the country selected in first grid ,
i did it like that:

bscCountries.datasource=GetAllCountries();
dgvCol_Countries.DataSource =bscCountries;
dgvCol_Countries.DisplayMember ="Name";
dgvCol_Countries.ValueMember = "ID";

bscCities.datasource=GetAllCities);
dgvCol_Cities.DataSource =bscCities;
dgvCol_Cities.DisplayMember ="Name";
dgvCol_Cities.ValueMember = "ID";

private void dgvTimeAtt_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
bsc_Cities.filter="CountryId="+dgvCol_Countries.Rows[e.RowIndex].Cell[e.CellIndex].value;
}
that's work fine but , when i go to next row in the grid and select other country the selected city i choose is gone .
How can i fix it?

Need regular expression for spliting string

Hi friends,
I need to split the line which I am reading from a csv file using ,(comma). But I need to skip the commas which are coming inside quote.For example for line
1,12/12/2008,"This is test, test2"
The result should be

1<br />
12/12/2008<br />
"This is test, test2"

not like

1<br />
12/12/2008<br />
"This is test, <br />
test2"

Please guide me to do this with regular expression or by any other method.
Thanks in advance

Personally I'd iterate over each character in the string, adding it to a stringbuilder and outputting the result on a comma or end of line. Use a boolean toggle on double quotes to disable in quote commas.
