When we open Windows notepad application then open a file, changes it contents and save it, it simply gets saved without opening the Save File dialog. But in the notepad program I have created above the Save File dialog opens on clicking 'Save' after changing the contents of saved file. Although the same file name appears in the save file dialog but on clicking 'Save' it gives a message "The same file name already exists. Do you want to replace it?". That is what I want to remove and make the changed contents saved directly to the opened file without opening the save file dialog.
Set sfd.OverwritePrompt = false any time after construction and before ShowDialog to suppress the overwrite warning.
You want to have two choices to save: A 'Save As..' button and a 'Save' button. You can create a string to hold the path of the opened file. The location may also change if the user specifies a new location when they save the file. If the user did not open the file, the 'Save As...' button would open the regular Save File Dialog. Once the user specifies the location of their document, you can save the file path to that string and use a `StreamWriter' to save it without the dialog:
...
using System.IO;
...
public partial class Form1 : Form
{
SaveFileDialog sfd = new SaveFileDialog();
OpenFileDialog ofd = new OpenFileDialog();
public string contents = string.Empty;
//string to hold file location
string currentFileLoc;

this.Text = "Untitled";

I suggest you also enclose the using(...){ } block in a try/catch statement and handle any exceptions.
What you need to do is save the filename entered, then, when the save option is pressed, check for a previously entered filename. If you have one, skip showing the dialog and just execute the save code.

So, my question is, how can i save items (buttons) in FlowLayoutPanel and how to load them later?
Thank you for your answers!
You should create a class for your items (game buttons), including their Title, Image etc. Then you can save them using XML.
class Game
{
// Properties here
}
This link will provide you with a quick How-to on how to accomplish this.
For saving images you can convert the image to base64 and convert it back to an image when loading the XML file again.
When I click on the file drop down where I have new, for new file, I prompt the user. If they have data in the textbox, if they would like to save what they have done before starting a new file. I get the save prompt dialog box to pop up and all that but I wont save the file.
private void mnuFileNew_Click(object sender, EventArgs e)
{
if (txtText.Text.Trim().Length <= 0)
{
lblStatus.ForeColor = Color.BlueViolet;
lblStatus.Text = "New file!";
}
else
{
if (MessageBox.Show("Start new file without saving?", "Exit",
MessageBoxButtons.YesNo, MessageBoxIcon.Question) == System.Windows.Forms.DialogResult.No)
{
try
{
SaveFileDialog sfd = new SaveFileDialog();
// set properties
sfd.Title = "Where would you like to save this?";
sfd.InitialDirectory = #"c:\Users\public";
sfd.Filter = "Text File (*.txt)|*.txt|All files (*.*)|*.*";
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
lblStatus.Text = sfd.FileName;
lblStatus.ForeColor = Color.Navy;
}
// show a message
lblStatus.ForeColor = Color.BlueViolet;
lblStatus.Text = "The Text has been uploaded!";
}
catch (Exception ex)
{
lblStatus.ForeColor = Color.Red;
lblStatus.Text = ex.Message;
}
}
else
{
txtText.Text = "";
}
you need to create the file
if(sfd.ShowDialog() == DialogResult.OK)
{
using(StreamWriter sw = new StreamWriter(sfd.FileName))
{
sw.WriteLine(YourTextBox.Text);
}
}

Thanks all for the help
private void button3_Click(object sender, EventArgs e)

toepassing.Lastfile = openFileDialog1.FileName;// Dont do this
fileBox.Text = openFileDialog1.FileName; //or this
Its unclear to me why you are holding onto an Open file dialog I would personally do the following
using(OpenFileDialog ofd = new OpenFileDialog())
{
if(ofd.ShowDialog() == DialogResult.OK)
{
classStringVariable = ofd.FileName;
fileBox.Text = ofd.FileName;
}
}
Then in button 3
toepassing.LastFile = classStringVariable ;
fileBox.Text = classStringVariable ;
When you use the Form Designer to add an OpenFileDialog control on you form, the designer assigns at the property FileName the value openFileDialog1.
I suppose you have set something as the initial value for the property FileName. Then in button_click3 you have no mean to check for the DialogResult and thus you get inconditionally this default back.
Fix it removing this default from the designer FileName property
Just add openFileDialog1.FileName= ""; before you show the dialog.
openFileDialog1.Filter = "Srec Files (.a20; .a21; .a26; .a44)|*.a20; *.a21; *.a26; *.a44|All files (*.*)|*.*";
openFileDialog1.Title = ("Choose a file");
openFileDialog1.InitialDirectory = Path.Combine(Directory.GetCurrentDirectory());
openFileDialog1.RestoreDirectory = true;
openFileDialog1.FileName = "";
if (openFileDialog1.ShowDialog() == DialogResult.OK && openFileDialog1.FileName != "")
{
fileBox.Text = (System.IO.Path.GetFileName(openFileDialog1.FileName));
}
In your button3_Click event you're checking for an empty string file name anyways, so they would get the correct error message and they wouldn't have some weird arbitrary default name show up when they open the dialog.
i have problem with closing saveFileDialog. when i click'cancel' window appears once again. here is my code:
private void SaveAsItem_Click(object sender, EventArgs e)
{
saveFileDialog1.FileName = "untitled";
saveFileDialog1.Filter = "Text (*.txt)|*.txt";
saveFileDialog1.ShowDialog();
System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(saveFileDialog1.FileName);
if (saveFileDialog1.ShowDialog()==DialogResult.Cancel)
{
richTextBox1.Text = "CANCEL";
issaved = false;
}
else
{
issaved = true;
SaveFile.WriteLine(richTextBox1.Text);
}
SaveFile.Close();
}
You're calling saveFileDialog1.ShowDialog() twice, once to show it and once to get the result. You only need to call it once. Remove the line that says, saveFileDialog1.ShowDialog(); by itself, you're already doing that inside the if condition.
Edit: you'll also need to move all the FileStream operations inside of the else block for it to work properly after you remove that line. Here is my edited version:
private void SaveAsItem_Click(object sender, EventArgs e)
{
saveFileDialog1.FileName = "untitled";
saveFileDialog1.Filter = "Text (*.txt)|*.txt";
if (saveFileDialog1.ShowDialog()==DialogResult.Cancel)
{
richTextBox1.Text = "CANCEL";
issaved = false;
}
else
{
System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(saveFileDialog1.FileName);
issaved = true;
SaveFile.WriteLine(richTextBox1.Text);
SaveFile.Close();
}
}
You could also skip the FileStream altogether an just do a File.WriteAlltext(saveFileDialog1.FileName, richTextBox1.Text).
If I set path = "C:\\MSREAD.txt"; and Click on SaveAs Menu Item ,it saves Filetext,But If I dont give the String path and save it from saveFD.FileName it doesnt work.Please help me with this issue.
Thanks a lot

outputFile.WriteLine(saveAllText);
}
}

}
}
Here is your problem:
richTextBox1.SaveFile(path, RichTextBoxStreamType.PlainText);
SaveMyTextBoxContents(path);
You first save the richTextBox text to file, but then override the same file with SaveMyTextBoxContents, However the file is empty because of SaveMyTextBoxContents method will only save something if some conditions are true "not selected item and both check boxes are checked", and the listBoxItems.Items.Count > 0 which apparently not the case
