I am trying to bypass the save dialog box when using the SaveFileDialog class. I want to be able to write to a document without having to prompt a user to decide if they want to save or not, the file should automatically save when they click a button.
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
saveFileDialog1.RestoreDirectory = true ;
saveFileDialog1.InitialDirectory = #"C:\";
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
// Code to write the stream goes here.
}
I have tried removing the if statement as well as using...
saveFileDialog1.CreatePRompt = false;
Nothing seems to work... Any ideas?
I think you want to bypass the overwrite prompt dialog.
In this case you can use
saveFileDialog1.OverwritePrompt = false;
Otherwise, you don't need a SaveFileDialog and you can save your stream without using it.
I found my answer. The question I asked was actually two it seems. The first was how to bypass SaveFileDialog, I wanted to use saveFileDialog because it can remember the last folder it accessed and opens to that folder when performing a read/save. That being said I implemented this...
Directory = System.AppDomain.CurrentDomain.BaseDirectory;
This will set Directory to the location of my executable.
Next I got rid of SaveFileDialog and just wrote to a file without ever prompting the user.
Thanks for all the pointers and ideas!
The end result ended up...
Directory = System.AppDomain.CurrentDomain.BaseDirectory;
using(System.IO.StreamWriter file = new System.IO.StreamWriter(Directory, false))
{
// File contents
}
Works perfectly for what I need it for.
If you want to save but you need the user to pick a filename, I would use this:
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
//setup properties of Dialog
bool filenamepicked = false;
while (!filenamepicked)
{
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
//Save file
filenamepicked = true;
}
else
{
MessageBox.Show("You have to use a file name.");
}
}

I am trying to get the handler to a SaveFileDialog which is opened by a button click of my WPF app. All the examples that I could find in the net actually creates one , but I need to handle one which is already opened. How do I do that?
The below code always creates a new SaveFileDialog
dlg.DefaultExt = "pdf"; // Default file extension
dlg.Filter = "PDF File (*.pdf)|*.pdf|All files (*.*)|*.*"; // Filter files by extension
dlg.FilterIndex = 2;
dlg.InitialDirectory = "C:\\Users\\Reema.Sinha\\Downloads";
Manager.Current.DialogMonitor.AddDialog(dlg);
DownloadSaveButton.Click();
DialogResult result = dlg.ShowDialog();
I guess OpenFileDialog can also do the trick. But I will prefer SaveFileDialog only. I tried this and hope it works for you also:
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.DefaultExt = "pdf"; // Default file extension
dlg.Filter = "PDF File (*.pdf)|*.pdf|All files (*.*)|*.*"; // Filter files by extension
dlg.FilterIndex = 2;
dlg.InitialDirectory = "C:\\Users\\Reema.Sinha\\Downloads";
Manager.Current.DialogMonitor.AddDialog(dlg);
DownloadSaveButton.Click();
Nullable<bool> result = dlg.ShowDialog(); // Show save file dialog box
if (result == true)
{
// Save document
string filename = dlg.FileName;
}
UPDATE:
Use FolderBrowserDialog. Then after you show the dialog to the user, you can do dlg.SelectedPath.
Hopefully these posts are helpfull to you.
SaveFileDialog that permits selection of folder

I am trying to download a file from a URL and I want to have a Popup where I can decide where to save the file on my pc. I know how to save it to a setlocation but that's not what I want.
WebClient webClient = new WebClient();
webClient.DownloadFileAsync(new Uri("URL"), #"d:\location");
So I get that this is how I download it so a set location but I need to be able to save it to a location of choice with the usual popup you normally get when you download anything.
To give more sight into this I have 2 radiobuttonlists in which the user can check what topics he wants then he can choose from a dropdownlist which file he wants to download and then he click on a downloadbutton which should trigger the download of that file.
Use DownloadFileAsync and listen to DownloadFileFinished. First download it to temp file and at event DownloadFileFinished, show popup and ask where to save. Then just copy the file from temp file to the filename from user.
-or-
Show SaveFileDialog before you start DownloadFileAsync.
Talking about a desktop app you can use SaveFileDialog.
The msdn code example:
private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream ;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
saveFileDialog1.FilterIndex = 2 ;
saveFileDialog1.RestoreDirectory = true ;
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
}
}
}
I need to create and write to a .dat file. I'm guessing that this is pretty much the same process as writing to a .txt file, but just using a different extension.
In plain english I would like to know how to:
-Create a .dat file
-Write to it
-And save the file using SaveFileDialog
There are a few pages that I've been looking at, but I think that my best explanation will come from this site because it allows me to state exactly what I need to learn.
The following code is what I have at the moment. Basically it opens a SaveFileDialog window with a blank File: section. Mapping to a folder and pressing save does not save anything because there is no file being used. Please help me use this to save files to different locations.
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "";
dlg.DefaultExt = "";
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
string filename = dlg.FileName;
}

Note that the SaveFileDialog only yields a filename but does not actually save anything.
var sfd = new SaveFileDialog {
Filter = "Text Files (*.txt)|*.txt|All files (*.*)|*.*",
// Set other options depending on your needs ...
};
if (sfd.ShowDialog() == true) { // Returns a bool?, therefore the == to convert it into bool.
string filename = sfd.FileName;
// Save the file ...
}
Use the filename you are getting from the SaveFileDialog and do the following:
File.WriteAllText(filename, contents);
That's all if you intend to write text to the file.
You can also use:
File.WriteAllLines(filename, contentsAsStringArray);
using(StreamWriter writer = new StreamWriter(filename , true))
{
writer.WriteLine("whatever your text is");
}
I have a console application in which we are creating xlsx files using OPENXML, we are able to create xlsx file & save it into specific folder in application.
But Now we want to show that file as a Save/Open dialog pop up. Then we can able to specify a particular path to save/ to open the existing files.
I am new to this OpenXml, Can anyone please help me on this to proceed further? How can I acheive this? Do we have any built-in DLL for this?
Thanks.
se the Save file dialog. It will prompts the user to select a location for saving a file. After that you can use saveFileDialog.FileName.ToString() property to get the full path.
See the sample code below:
//Save a file in a particular format as specified in the saveAsType parameter
private void OpenSaveFileDialog(int saveAsType)
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.InitialDirectory = Convert.ToString(Environment.SpecialFolder.MyDocuments);
saveFileDialog.Filter = "CSV|*.csv|Excel|*.xlsx";
saveFileDialog.FilterIndex = saveAsType;
saveFileDialog.Title = "Save Data";
saveFileDialog.FileName = "My File";
saveFileDialog.ShowDialog();
if (saveFileDialog.FileName != "")
{
//File Path = m_fileName
m_fileName = saveFileDialog.FileName.ToString();
//FilterIndex property is one-based.
switch (saveFileDialog.FilterIndex)
{
case 1:
m_fileType = 1;
break;
case 2:
m_fileType = 2;
break;
}
}
}

I am currently working Open file and write file functions in C#. I am going through two problems: When the user is in the process of saving a file, if he/she exits the save dialog and nothing is saved I get an error(look at picture below for description). How can my program avoid this and not crash? and Is there away to display a message after the file has been saved?
private void button2_Click(object sender, EventArgs e)
{
SaveFileDialog saveReport = new SaveFileDialog();
saveReport.Filter = "Text Files | *.txt";
saveReport.ShowDialog();
StreamWriter writeFile = new StreamWriter(saveReport.FileName);
writeFile.Write(textBox1.Text);
writeFile.Close();
}
If the user clicks Cancel, ShowDialog() will return DialogResult.Cancel.
You can check for this in an if statement.
You could do something like this:
var saveReport = new SaveFileDialog();
saveReport.Filter = "Text Files | *.txt";
var result = saveReport.ShowDialog();
if(result == DialogResult.Cancel || string.IsNullOrWhiteSpace(saveReport.FileName))
return;
using(var writer = new StreamWriter(saveReport.FileName))
{
writer.Write(textBox1.Text);
writer.Close();
}
MessageBox.ShowDialog("File Saved!");
In principle the FileName will never be null or whitespace -- the dialog prevents it unless you cancel, but I include it for clarity.
Use the return value of your ShowDialog call to determine what the user selected.
The code below saves only if the user selected OK in the dialog:
SaveFileDialog saveReport = new SaveFileDialog();
saveReport.Filter = "Text Files | *.txt";
if (saveReport.ShowDialog() == DialogResult.OK) {
StreamWriter writeFile = new StreamWriter(saveReport.FileName);
writeFile.Write(textBox1.Text);
writeFile.Close();
}
The problem with your original code was that you were attempting to save even if the user did not specify a file name through the dialog.
