Datagridview Comboboxes C#

Hi there,

i finally got a Problem Smile | :)

I have a DataGridView and in 2 cloumns there are comboboxes.

Now, what my question is:

In the first Combobox there are resources diplayed, in the second one roles.
If i choose one of the roles the resource box is refilled with resources that fit the selected role.

But the Problem is that after adding multiple rolerestrictions in the second comboboxes i only have the resource result of the last added row.

How do i get the comboboxes to work per row not as a coloumn ?

It should work like this:
----cb1----------cb2
TBD TL Res----Teamleader <- only teamleader resources avail
TBD SW Eng----Software Engineer <- only Software Engineers avail
TBD Proj M----Project Manager <- only Project Managers avail

Hope this Question is not 2 squishy

if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");
}

Solved it my self Smile | :)

Was quite easy in the end ... Blush | :O

here the Code, i marked the passages i didn't know:

private void dataGridViewX2_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (!_doEvent)
            {
                if (sender.GetType().ToString() == "DevComponents.DotNetBar.Controls.DataGridViewX")
                {
                    DevComponents.DotNetBar.Controls.DataGridViewX _temp = (DevComponents.DotNetBar.Controls.DataGridViewX)sender;
                    if (e.ColumnIndex == 5)
                    {
                        Worker.Items.Clear();
                        _rawBenDivFaeh = new IMS_Modelle.BenDivFaeh(_parent.IMSDB, "").ReadAllRoleRelated(_rawRoles.Find(
                                                                    rr => rr.RoleName == dataGridViewX2[e.ColumnIndex,e.RowIndex].Value.ToString()).IdRole);
                        for (int i = 0; i < _rawRes.Count; i++)
                        {
                            if (_rawBenDivFaeh.Exists(rbdf => rbdf.IdResource == _rawRes[i].IdEmployee))
                            {
                                _doEvent = true;
                                DataGridViewComboBoxCell _cell = new DataGridViewComboBoxCell();
                                _cell.Items.Add(_rawRes[i].Name + ", " + _rawRes[i].FirstName);
                                dataGridViewX2.Rows[e.RowIndex].Cells["Worker"] = _cell;
                                _doEvent = false;
                            }
                        }
                    }
                }
            }
        }

Just cell = Combobox ... Sometimes i feel WTF | :WTF:

if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");
}

XML load into a variable or file

Hi,

1> I am writing a code which will call a web-service and populate xml data into a variable and then processing that data to a database table.

2> I am writing a code which will call a web-service and retrieve the XML data and write into a file(XML). And then it will process the data from that XML file to a database table.

My question is: Which is the best way: "1" or "2".
thinking all scenarios ..means
if volume of data will be more in future
performance
data reliability
flexibility,etc..

Kindly share your opinion !!

Obviously, option 1 is your best bet. I assume by 'variable' you mean a data structure that can hold your xml in memory.

What is the purpose of storing it in a file? If you're concerned about losing data due to write speed and the load on the database, consider using an MQ solution. Besides being slow, writing to file requires lot of disk space and is prone to file locking issues and also requires periodic cleanup.

Depends on various factors.

For starters what exactly do you mean by "volume". Do you have actual realistic numbers?
For example if you have 1 record a day now and 10 in three years it doesn't matter.
If you have 100,000 a day now and expect, realistically, 10 million at the end of the year then that is a different matter.

Also do you need to process the XML before putting into the database?

What happens if you go to the web-service right now and it isn't up? And it stays down until tomorrow? What happens if your database is down and stays down until tomorrow?

Hi guys

I am having this problem, I wrote a small app to display the computers hostname and IP address.

Hostname horks no problem, the issue I am sitting with is...

On some Windows 7 / 8 computers is displays the IPv6 Frown | :(

How do I force to only return IPv4 everytime?

This is my Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;

namespace IPChecker
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
label1.Text = "Host Computer: " + Dns.GetHostName();
foreach (IPAddress address in Dns.GetHostAddresses(Dns.GetHostName()))
{
label2.Text = "IP Address: " + address;
}
}
}
}
