Combobox help...

Dave McCool5-Mar-06 23:45

I have a comboBox with 12 Items in it. I want to use a If statement for each of the items, so when you choose one, something happens. Like this:

{
if (comboBox1.SelectedIndex >= 0)
MessageBox.Show("Item 1 selected");
}

Only I want an if statement for 12 items insted of one. How would I do this in C# .net 2003?

In the end we're all just the same

You can use switch:

switch (comboBox1.SelectedIndex) {<br />
case 1: MessageBox.Show("One"); break;<br />
case 2: MessageBox.Show("Two"); break;<br />
case 3: MessageBox.Show("Three"); break;<br />
...<br />
case 12: MessageBox.Show("Twelve"); break;<br />
}

I have classes:

public class Database
{// }

public class Baseservices
{
private ArrayList m_arrErrors;
protected Database m_DB;
protected SqlDataAdapter m_DA;
protected SqlCommandBuilder m_CB;
Protected DataSet m_DS;
protected BaseServices(Database DB, string strSQL)
{
m_DB = DB;
m_DA = new SqlDataAdapter(strSQL, m_DB.Connection);
m_CB = new SqlCommandBuilder(m_DA);
m_DS = new DataSet();
m_DA.Fill(m_DS);
}

protected void SaveRow(DataRow dr)
{
DataColumn val;
if (m_DS.Tables(0).Rows.Count == 0) {
m_DS.Tables(0).Rows.Add(dr);
return;
}
m_DS.Tables(0).Rows(0).BeginEdit();
foreach (int val in m_DS.Tables(0).Columns) {
m_DS.Tables(0).Rows(0).Item(val) = dr.Item(val);
}
m_DS.Tables(0).Rows(0).EndEdit();
}

Public Class File: BaseServices
{
Public File()
{base.new(New Database(), “SELECT * FROM tblFiles WHERE 1=0”)}

Public File(ref Database db)
{base.new(db, “SELECT * FROM tblFiles WHERE 1=0”)
}
Public File(ref Database db,ref int ID)
{base.new(db, “SELECT * FROM tblFiles WHERE pkFileID = “& ID.ToString);}
public void Validate()
{
DataRow dr;
ClearErrors();
foreach (int dr in m_DS.Tables(0).Rows) {
if (dr.RowState == DataRowState.Added | dr.RowState == DataRowState.Modified) {
ValidateRow(dr);
}
}
}

public overide void SaveRow(ref DataRow dr)
{
if(dr[“fkTeamID”]=null)
dr[“fkTeamID”] = 0;
i(dr[“CreationDate"]=null)
{dr[“CreationDate”] = date.today();}
MyBase.SaveRow(dr);
Validate();
}

}

Error in method SaveRow, I understand, Please tell me!
Thanks very much. (My English is very badly, sorry)

What kind of error? Compiling error? Runtime error? What is the error message?

I see that most of your quotation marks are typographic quotes (“,”), not the inch character (") that is used when programming. Is that so also in the code that you are using, or did it happen on the way to the forum?

I want to ask you about this code follow:

public class File: BaseServices
{
public File()
{base.new(New Database(), “SELECT * FROM tblFiles WHERE 1=0”)}

public File(ref Database db)
{base.new(db, “SELECT * FROM tblFiles WHERE 1=0”)
}
Public File(ref Database db,ref int ID)
{base.new(db, “SELECT * FROM tblFiles WHERE pkFileID = “& ID.ToString);}

Class File inherites BaseService and how contructors of File wrong?

Guffa6-Mar-06 0:39

You don't have a static method called "new" in the BaseServices class. Are you trying to call the constructor of the base class? Then it's done like this:

public File() : base(new Database(), "SELECT * FROM tblFiles WHERE 1=0") {}

I don't what your error is, but this is wrong:

phuonghoyden wrote:
if(dr[“fkTeamID”]=null)
dr[“fkTeamID”] = 0;

if should be:

if(dr[“fkTeamID”]==null)
dr[“fkTeamID”] = 0;

Then you have to have a program running, or a service, that checks the time periodically to know when to run the function.

You may need to use a thread which does that so that main UI does not support unresponsiveness.

Network text editor

Dave McCool5-Mar-06 22:35

how to delete all records with datarow ?

5-Mar-06 22:35

I have created a basic text editor and I want to add a function so two computers that are linked together via network can edit the same document if they are both running the text pad. I have a menu called networking and I want a menu item called mnuconnect to connect you to the other computer. It will then detect if the other user is suing the text pad and if it says yes, you click on it and it sends a message which says: "<username> wantes to connect to your text pad." OK to continue cancel to get a message saying "<username> has denied you access"

I have a chat box and send button on bottom of text pad so that two users can communicate> When you click send it will display the contents of whats in the text box txtchat to the other computer via a message box. When Message box and it only has a OK box.

How would I do any of these

In the end we're all just the same
