im trying to create program that changes format of imported images i dont know how to save it any help would be appreciated
--Edit; im trying save each file imported to specific folder with selected format
my code ;
private void button1_Click(object sender, EventArgs e)
{
if (dialog.ShowDialog() == DialogResult.OK)
{
foreach (String file in dialog.FileNames)
{
listView1.Items.Add(System.IO.Path.GetFileNameWithoutExtension(file));
string filee = saveFileDialog1.FileName;
}
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
foreach (ListViewItem item in listView1.SelectedItems)
{
listView1.Items.Remove(item);
}
}
}
}
var image = System.Drawing.Image.FromFile(inputFilename);
image.Save(outputFileName, System.Drawing.Imaging.ImageFormat.Gif);
That should do it, if I'm not mistaken. You load an image into memory from a file, then save it given whatever format you want, I chose gif here as an example.

I'm sure this is really simple to do but I'm struggling.
I've 6 Textboxes and I would like to copy them in Clipboard and paste them to others.
So to copy I do:
private void Btn_Copy_P1_Click(object sender, EventArgs e)
{
StringBuilder cop = new StringBuilder();
cop.AppendLine(X_Point_1_Rob.Text);
cop.AppendLine(Y_Point_1_Rob.Text);
cop.AppendLine(Z_Point_1_Rob.Text);
cop.AppendLine(Rx_Point_1_Rob.Text);
cop.AppendLine(Ry_Point_1_Rob.Text);
cop.AppendLine(Rz_Point_1_Rob.Text);
Clipboard.SetText(sb.ToString());
}
private void Btn_Paste_P2_Click(object sender, EventArgs e)
{
Clipboard.GetText()
// How it's possible to paste the 6 values from Clipboard ?
}
Do you have a working method or a solution?
Something like this, maybe?
private void Btn_Paste_P2_Click(object sender, EventArgs e)
{
string[] text = Clipboard.GetText()?.Split('\\n');
if(text == null || text.Length == 0)
return;
X_Point_1_Rob.Text = text[0];
Y_Point_1_Rob.Text = text[1];
...
Rz_Point_1_Rob.Text = text[5];
}
By the way, where do you want to paste copied snippets of text?
You can try below solution.
// Copy text to the clipboard.
private void btnCopy_Click(object sender, EventArgs e)
{
Clipboard.SetText(txtCopy.Text);
}
// Paste text from the clipboard.
private void btnPaste_Click(object sender, EventArgs e)
{
txtPaste.Text = Clipboard.GetText();
}

Basically I was attempting to use an open file dialog and a list box to list recently opened files in a list box also yes I do use fastcoloredtextbox why do 90% of people I talk to hate it also sorry if the code looks like it was designed by some depressed 11 year old because I am very new.
private void button5_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
string fm = openFileDialog1.FileName;
string rf = File.ReadAllText(fm);
fastColoredTextBox.Text = rf;
string files = Path.GetFileName(fm);
foreach (string file in files)
{
listBox1.Items.Add(file);
}
}
Also it looks unfinished because it is unfinished - I've been trying to fix this and it just kept making more errors so like yea uhh help random people on the internet who I don't know uhh I'm going to stop randomly typing things now
wow edit #3 if it helps anyone I'm having the error on
foreach (string file in files)
First you have to add a new Instance of var openFileDialog = new OpenFileDialog(); if you don't have. Then you could do something like this to get the text of the file and add it to you listbox:
private void button5_Click(object sender, EventArgs e)
{
var openFileDialog = new OpenFileDialog();
if (openFileDialog.ShowDialog() == true)
{
var file = openFileDialog.FileName;
var text = File.ReadAllText(file);
fastColoredTextBox.Text = text;
var filename = Path.GetFileName(file);
listBox1.Items.Add(filename);
}
}
Also you do not have to do this:
foreach (string file in files)
because Path.GetFile() returns only a string with your FileName. So you can add it directly to your ListBox.

I need a way to filter variable name of a list, I want to update the filter as fast as i write in the textbox. and add the game to forms Listbox.
structure of list is:
public class Games
{
public string ID;
public string Name;
public string Password;
}
here's my code so far:
List<Games> games = new List<Games>();
private void textBox10_TextChanged(object sender, EventArgs e)
{
d2ngList.Items.Clear();
foreach(Games game in games)
{
//Filter List
d2ngList.Items.Add(game.Name);
}
}
I don't see any filtering in your code, so maybe its your problem. You can use LINQ to filter games by name:
private void textBox10_TextChanged(object sender, EventArgs e)
{
string filter = textBox10.Text;
d2ngList.Items.Clear();
foreach(Games game in games.Where(g => g.Name.Contains(filter)))
{
d2ngList.Items.Add(game.Name);
}
}
Also you can optimize your code with AddRange method:
string filter = textBox10.Text;
d2ngList.Items.Clear();
string[] names = games
.Where(g => g.Name.Contains(filter)).Select(g => g.Name).ToArray();
d2ngList.Items.AddRange(names);
i figured out a solutin
private void textBox10_TextChanged(object sender, EventArgs e)
{
d2ngList.Items.Clear();
foreach(Games game in HandlerClass.Instance.Games)
{
if (!string.IsNullOrEmpty(textBox10.Text))
{
if (game.Name.Contains(textBox10.Text))
d2ngList.Items.Add(game.Name);
}
else
d2ngList.Items.Add(game.Name);
}
// games.Where(item => filterList.Contains(item));
}

My application prints without showing the PrintDialog (and it need to do so) but I'd like to be able to set to which printer it should print so I added an appsetting in the app.config where it stores the printer name. what I want is a dialog where it shows all printer and the user should be able to choose a printer and it will save in the app.config (I could actually do it from the PrintDialog and get the chosen printer but the button says Print and I don't want to confuse the User...)
Thanks
edit
#methodMan Asked for code so I added My code
System.Windows.Forms.PrintDialog ps = new System.Windows.Forms.PrintDialog();
//set the selected printer in the dialog to the current printer
ps.PrinterSettings.PrinterName = MyApp.Properties.Settings.Default.ContinuesLabelPrinter;
var result = ps.ShowDialog();
if(result == System.Windows.Forms.DialogResult.OK)
{
MyApp.Properties.Settings.Default.ContinuesLabelPrinter = ps.PrinterSettings.PrinterName;
}
OK here is something that will work for you I think...Create a windows Form with a listbox and two buttons.
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
{
listBox1.Items.Add(printer);
}
}
private void button1_Click(object sender, EventArgs e)
{
this.Close();
}
private void button2_Click(object sender, EventArgs e)
{
this.DialogResult = System.Windows.Forms.DialogResult.OK;
}
}
In your code do this:
Form2 form2 = new Form2();
if(form2.Show() == System.Windows.Forms.DialogResult.OK)
{
MyApp.Properties.Settings.Default.ContinuesLabelPrinter = form2.listBox1.SelectedItem.ToString();
}
form2.Dispose(); // <-- this might not be necessary
You will need to make the listBox1 public for this to work.

The program has a panel which holds a text box and the panel has two buttons on each side.
Each button acts as a 'next' (>>) and 'previous' (<<) navigation. I want to be able to navigate to the next panel by clicking '>>' this will clear the text box. Then when I click '<<' I want to go back to the previous panel with the text box containing the data previously added. However I want to do this without having to create two panels on top of each other and setting the visibility to true or false (which I am able to do). I want to achieve this by using only the one panel so the process can be done an infinite number of times. I hope this is clear to understand if you require more information please let me know.
Here is an image of my interface to clarify things:
since you have the page number, why not just create a list (or use a dictionary with the page number as a key), then in the button handler for >> and << collect the text for the current page (and put it in the list or dictionary) and replace it with the text for the previous page (from the list or dictionary).
code could look something like this:
public partial class Form1 : Form
{
Dictionary<Decimal, String> TextInfo;
public Form1()
{
InitializeComponent();
TextInfo= new Dictionary<Decimal, String>();
}
private void Form1_Load(object sender, EventArgs e)
{
numPage.Value = 1;
}
private void bnForward_Click(object sender, EventArgs e)
{
if (TextInfo.ContainsKey(numPage.Value))
{
TextInfo[numPage.Value] = textBox1.Text;
}
else
{
TextInfo.Add(numPage.Value, textBox1.Text);
}
numPage.Value++;
if (TextInfo.ContainsKey(numPage.Value))
{
textBox1.Text = TextInfo[numPage.Value];
}
else
{
textBox1.Text = "";
}
}
private void bnBack_Click(object sender, EventArgs e)
{
if (numPage.Value == 1)
return;
if (TextInfo.ContainsKey(numPage.Value))
{
TextInfo[numPage.Value] = textBox1.Text;
}
else
{
TextInfo.Add(numPage.Value, textBox1.Text);
}
numPage.Value--;
if (TextInfo.ContainsKey(numPage.Value))
{
textBox1.Text = TextInfo[numPage.Value];
}
else
{
textBox1.Text = "";
}
}
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
}
}
