i just made a file editor, it contains a listview and a textbox, i made that when i select and item from the list view it appears in the textbox, the text is japanese, and when i select a japanese text or line, it gives me an error: InvalidArgument: Value '0' is not valid for 'index'
can you guys help me ? this is my code:

}
private void menuItem12_Click(object sender, EventArgs e)

}
Before accessing the SelectedItems index, you should check if there are any items selected.
private void button1_Click(object sender, EventArgs e)
{
if(listView1.SelectedItems.Count > 0)
textBox1.Text = listView1.SelectedItems[0].SubItems[1].Text;
}
You may also want to perform a check to ensure that SubItems has an index of 1 before using it.

The problem is that in line
series.Points.AddXY(System.DateTime.Now, Values[i]);
you are adding points with the same X value set to System.DateTime.Now. In result you have only one point on axis X.

Hello I'm trying to click a button to remove and item but I keep getting an
'IndexOutOfRange' Exception.
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
clientNum = clientList.Items.Count;
for (int i = 0; i < clientNum; i++)
{
nameSeletion[i] = clientList.Items[i].ToString();
}
if (dateSeletion[clientList.SelectedIndex] != null)
{
dateCalender.SelectionStart = todayDate[clientList.SelectedIndex];
Check();
}
else
{
nameLbl.Text = nameSeletion[clientList.SelectedIndex];
dateText.Text = "";
}
}
The if (dateSeletion[clientList.SelectedIndex] != null) is where I'm having the error.
The button code is
private void button1_Click(object sender, EventArgs e)
{
clientList.Items.Remove(clientList.Items[clientList.SelectedIndex]);
}
the dateSelection is defined in the save button and Initialization
private void SaveBtn_Click(object sender, EventArgs e)
{
//save the list array for names
for (int i = 0; i < clientNum; i++)
{
nameSeletion[i] = clientList.Items[i].ToString();
}
dateSeletion[clientList.SelectedIndex] = dateCalender.SelectionStart.Date.ToShortDateString() +
" " + clientTime.Value.ToShortTimeString();
todayDate[clientList.SelectedIndex] = dateCalender.SelectionStart;
dateCalender.BoldedDates = todayDate;
Check();
}
public ClientForm()
{
InitializeComponent();
clientNum = clientList.Items.Count;
todayDate = new DateTime[clientNum];
dateSeletion = new string[clientNum];
nameSeletion = new string[clientNum];
clientTime.CustomFormat = "hh:mm tt";
//initialize the list array for names
for (int i = 0; i < clientNum; i++)
{
nameSeletion[i] = clientList.Items[i].ToString();
}
}
Try this
clientList.RemoveAt(clientList.SelectedIndex);
I have looking for the solution but still found nothing
Here is my code:
private void Form1_Load(object sender, EventArgs e)
{
RichTextBox rtb = new RichTextBox();
rtb.Text = File.ReadAllText(#"C:\Users\Admin\Desktop\myfile\customers.txt");
int i = 0;
foreach (string line in rtb.Lines)
{
if (line == "--")
{
ListViewItem item = new ListViewItem();
item.Text = rtb.Lines[i + 1];
item.SubItems.Add(rtb.Lines[i + 2]);
item.SubItems.Add(rtb.Lines[i + 3]);
item.SubItems.Add(rtb.Lines[i + 4]);
listView1.Items.Add(item);
}
i += 1;
}
}
private void button1_Click(object sender, EventArgs e)
{
Form2 pop = new Form2();
pop.ShowDialog();
string name = pop.name;
int age = int.Parse(pop.Age);
string dob = pop.DateOfBirth;
string addr = pop.Address;
StreamWriter write = new StreamWriter(#"C:\Users\Admin\Desktop\myfile\customers.txt",true);
write.Write("--\n");
write.Write("{0}\n",name);
write.Write("{0}\n",dob);
write.Write("{0}\n",age);
write.Write("{0}\n",addr);
write.Close();
}
The question is how do I reload the list view after I write the data into the text file?
Extract the logic out of Form1_Load
private void Form1_Load(object sender, EventArgs e)
{
RefreshListView();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 pop = new Form2();

write.Write("--\n");
write.Write("{0}\n",name);
write.Write("{0}\n",dob);
write.Write("{0}\n",age);
write.Write("{0}\n",addr);
write.Close();
RefreshListView();
}
private void RefreshListView()
{
listView1.Items.Clear();
RichTextBox rtb = new RichTextBox();
rtb.Text = File.ReadAllText(#"C:\Users\Admin\Desktop\myfile\customers.txt");
int i = 0;
foreach (string line in rtb.Lines)
{
if (line == "--")
{
ListViewItem item = new ListViewItem();
item.Text = rtb.Lines[i + 1];
item.SubItems.Add(rtb.Lines[i + 2]);
item.SubItems.Add(rtb.Lines[i + 3]);
item.SubItems.Add(rtb.Lines[i + 4]);
listView1.Items.Add(item);
}
i += 1;
}
}
I'm sorry that the title is confusing but I did not know how to ask this question; if someone can help with a better title I would appreciate it.
I am building a database of players and their match performance. The matches are displayed using a tab control, inside the matches are fields that are stored in a panel. The amount of matches goes up to 5, therefore each field is an array of size 5 to represent different values for different matches. I have ran into the problem of trying to save the amount of tabs (matches) there are for that unique player.
Because the amount of tabs carries over to the next player shown, I tried to iterate through all the matches and all the fields for that player, determine which matches contain empty fields and respectively delete that tab (match). So if player 1 has 3 matches with values in fields, but player 2 only has 2 matches that contain values in fields, the 3rd match (tab) will be deleted as the fields have no values.
to better explain, this is the GUI:
Picture
My attempt at iterating through the field of each match looks like this:
int[] csNumberTF = ((Player)GameDB[currentEntryShown]).csNumber[tabMatches.SelectedIndex];
int i = 0;
while (i < 5)
{
if (csNumberTF[i] == 0)
{
int tabsLeft = tabMatches.TabCount;
if(tabsLeft > 1)
tabMatches.TabPages.Remove(tabMatches.SelectedTab);
tabsLeft--;
}
i++;
}
However I am presented with the error: Cannot implicitly convert type 'int' to 'int[]'
I would really appriciate if someone could help me out here, I understand that the code is long but It is organised and titled so that should help.

Try change this
int[] csNumberTF = ((Player)GameDB[currentEntryShown]).csNumber[tabMatches.SelectedIndex];
int i = 0;
while (i < 5)
{
if (csNumberTF[i] == 0)
{
int tabsLeft = tabMatches.TabCount;
if(tabsLeft > 1)
{
tabMatches.TabPages.Remove(tabMatches.SelectedTab);
tabsLeft--;
}
}
i++;
}
To use the csNumber which is int[] in the for loop
int i = 0;
while (i < 5)
{
if (((Player)GameDB[currentEntryShown]).csNumber[i] == 0)
{
int tabsLeft = tabMatches.TabCount;
if(tabsLeft > 1)
{
tabMatches.TabPages.Remove(tabMatches.SelectedTab);
tabsLeft--;
}
}
i++;
}
To find out the value of tabMatches.TabCount, add this line when you run the program and see it in the output window: (To answer your question, I would assume the TabCount start with 1. That's the default value of any .Count() call to an array of integer. But this is the best way to know for sure.)
System.Diagnostics.Debug.WriteLine(tabMatches.TabCount);
I want to play a video like that guy did [link].
I'm working on C# Windows Form Application (not NXA).
But I don't know how.
I tried using Microsoft.DirectX.AudioVideoPlayback but no luck.

video = new Video(rihanna.FileName);

vdoTrackBar.Maximum = Convert.ToInt32(vdo.Duration);
And in some other Button Code to Start/Pause:
if (vdo.Playing)
{
vdo.Pause();
btnPlay.Text= "Play";
}
else
{
vdo.Play();
btnPlay.Text= "Pause";
}
BTW:
Don't name variables/members or something else in your Code after Girls...
If your aren't sure how to name it, there are some Guidelines here.
The goal is to provide a consistent set of naming
conventions that results in names that make immediate sense to
developers.
For AudioVideoPlayback to work, you'll need to add the AudioVideoPlayback reference, with Reference > Add Reference > Browse > C: > Windows > Microsoft.Net > DirectX for managed code > 1.0.2902.0 > Microsoft.DirectX.AudioVideoPlayback.dll
