I have some data and I would like to export it to excel. I did all the code, and everything is working fine, Now I want to save that excel file to the hard drive. I could do that too. but my problem is that I couldn't know how to allow the customer to set his/her own file name.
What I have tried:
FolderBrowserDialog brwsr = new FolderBrowserDialog();
//Check to see if the user clicked the cancel button
if (brwsr.ShowDialog() == DialogResult.Cancel)
return;
else
{
string newDirectoryPath = brwsr.SelectedPath;
//Do whatever with the new path
}
the problem of that method is it is just allows the users to select the folder that the want the file to be saved to. I want to all the user to specifiy the path and the file name.
Any idea to help pleaes?
many thanks
You need to use a SaveFileDialog instead. This let's the user specify a path + filename. Check this out for more info: SaveFileDialog on MSDN
SaveFileDialog is pretty similar to FolderBrowserDialog, so you can almost replace the existing code you already have ;)
Specify File Type (EDIT)
Have a look a the Filter property.
Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*

I'm using C# windows application .
I want to save files in my local system.
I used Open File dialog to attach the files.
Here the text inside the file is copying,I want the file itself to get copied with a new name.But what I am really looking for is , it should just save the file automatically and not show the SaveDialog Box?
How it can be done in windows application.Can anybody help me please?
The code is shown below:
private string GetFileName()
{
OpenFileDialog op1 = new OpenFileDialog();
DialogResult result = op1.ShowDialog();
if (result == DialogResult.OK) // Test result.
{
txtEn.Text = op1.FileName;
FileName = op1.FileName;
//MessageBox.Show(FileName);
File.Copy(op1.FileName, #"D:\Backup\");
}
return FileName;
}
SQL Server 2012 seems unrelated to your question. Provided that you have proper access rights to the target directory, then in order to automate the procedure (as per your question) you don't need to use the OpenFileDialog; just a single line should suffice the goal:
//Overwriting a file of the same name is not allowed
File.Copy(FileName, #"D:\Backup\" + FileName)
or
//Overwriting a file of the same name is allowed
File.Copy(FileName, #"D:\Backup\" + FileName, true)
You can also apply some additional logic pertinent to backup file naming (upon necessity).
Hope this may help. Best regards,
Are you trying to copy a file from some x location on your file system to y location (in your case D:\Backup folder) in the file system? If that is the requirement here, I see that you are using the FileName property of OpenFileDialog which gets the File path. This you are appending to D:\Backup. You should instead use the Path.GetFileName property to first extract the file name with extension and then append it to the new folder path
File.Copy(fileName, #"D:\Backup\" + Path.GetFileName(fileName));
I am trying to replicate the standard save file process where, if there already exists a file with the necessary file extension, it is pre-selected in the SaveFileDialog. In my program I am using SaveFileDialog to allow the user to select the path for the file on the system. Upon save, it will automatically open to the path that the last saved file was, but the user has to re-select it.
Here is where I think something like this would come into play in my code:
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = ".cct"; //The file extension
Nullable<bool> result = dlg.ShowDialog(); //Lets user select path
//**I'm guessing that the "pre-select" operation I am talking about
//would go here
directory = Path.GetDirectoryName(dlg.FileName); //Directory = File path on system
I have looked at the CheckFileExists property and it says that it "Gets or sets a value indicating whether a file dialog displays a warning if the user specifies a file name that does not exist." So it looks like it's more focused around checking whether or not the user enters a new file name.
How do I make it so that the previously saved file with the same extension is highlighted or selected in the SaveFileDialog if one is found upon save?
You can do a couple of things.
You could restore the path the user last saved with by setting dlg.RestoreDirectory = true.
Set the FileName before you show the dialog and it will automatically show that folder and insert the file name using dlg.FileName

My program has a treeview which lists files from a remote computer. What I need to do is to copy these files from remote into one of my local folders. I wish that when I right click the file in treeview, a dialog box shows up for me to choose a folder, and then I click "OK" in the dialog box, my clicked file could be saved inside that folder.
Since the path of the files in remote is unc path, I'm using
File.Copy(string remote_address, string local_address)
to copy the files. As i said before I need a dialog window to choose folders. So I've tried using a FolderBowserDialog, however its SelectedPath property returns me only the path to the folder not including the folder's name! And I haven't found any property to return me the folder's name.
So my questions are:
If there's a way allowing me to use FolderBowserDialog, that I could get the full path of the location where I save my file?
If there's another method allowing me to copy or download the files from remote, like using SaveFileDialog. The problem is I don't know how to us it to do this.
The following should work:
var fbd = new FolderBrowserDialog();
if(fbd.ShowDialog() == DialogResult.OK)
{
var localPath= Path.Combine(fbd.SelectedPath, Path.GetFilename(remote_address));
File.Copy(remote_address, localPath);
}
I'm not sure which "SavePath" property you are referring to, as FolderBrowserDialog has no such property. The property you are looking for is called SelectedPath.
FolderBrowserDialog dlg = new FolderBrowserDialog();
dlg.ShowDialog();
string local_address = dlg.SelectedPath;
After you call the FolderBrowserDialog's ShowDialog() method it will return a variable indicating what button the user pressed (ie, Ok or Cancel)
after you make sure the user had used "Ok" to indicate they want to proceed with the operation, you can access the "SelectedPath" field which will give you the full local path they selected.
You can then get the final path by calling
System.IO.Path.Combine(fbd.SelectedPath,remoteFileName);
I'm assuming that fbd is your FolderBrowserDialog instance and remoteFileName should contain just the filename part of the remote file (eg. "MyFile.txt");
If you want to separate the filename from the full remote path, use
var remoteFileName = System.IO.Path.GetFileName(remotePath);
That being said, what a user would typically expect is not a folder browser dialog, but the save file dialog.
you can initialize the save file dialog with a filename, leaving the user to select a folder and possibly change the intended file name as well if they wish.
SaveFileDialog sfd = new SaveFileDialog();
sfd.FileName = remoteFileName;
sfd.ShowDialog();
sfd.FileName // now contains the full path to the file that the user has selected
don't forget to take the result from the ShowDialog() call to make sure the user didn't cancel out of the save dailog!
I'm creating right now an application in C# which saves data to the file upon clicking a button. The name and locations of the file is defined by the user, and i want the program to automatically add .txt extension to the name, as well as show only 1 possible extensions in "save files as" combobox. I have this code:
SaveFileDialog Dialog1 = new SaveFileDialog();
Dialog1.DefaultExt = "txt";
Dialog1.Filter = "Pliki tekstowe | *.txt";
Dialog1.AddExtension = true;
private void button1_Click(object sender, EventArgs e)
{
if (Dialog1.ShowDialog() == DialogResult.OK)
{
System.IO.Stream fileStream = Dialog1.OpenFile();
System.IO.StreamWriter sw = new System.IO.StreamWriter(fileStream);
sw.WriteLine("Writing some text in the file.");
sw.WriteLine("Some other line.");
sw.Flush();
sw.Close();
}
this.Close();
}
But whenever i click the button, i have no options to choose from in the combobox, as well as the .txt extensions are not added to the file name in case the extensions is not specified by the user himself. I know i can somehow bypass that by checking if the user gave the proper extensions, and in case he didn't add ".txt" to the name but i really wanted to know, why that piecei of code doesn't function. Any help?
The problem is the space. Just change it to this:
Dialog1.Filter = "Pliki tekstowe|*.txt";
and you should be in business.
Otherwise it's trying to match files of the pattern *.txt (subtly compared to *.txt) - which you probably don't have.
take a look at the following example and see the difference:
http://msdn.microsoft.com/en-us/library/system.windows.forms.savefiledialog(v=vs.110).aspx
you should try firstly to add this to your filter:
"txt files (*.txt)|*.txt|All files (*.*)|*.*"
for completeness you should add the (*.txt) string in your filter for descriptive reasons (thanks for clarifying Yuck). Try it - see what happens :)
remember it is sensitive in terms of the string. so try not to put things like a space between the file extensions
I had a similar issue where the save dialog box on firefox and safari doesn't detect the file extension even though I had Content-Type header set to "application/pdf". The issue turned out to be spaces in the name of the file. I replaced the file name with '-' (hyphens) and that fixed it.
In a WPF app I need to make it possible for a user to pick a file by the standard Open File Dialog and save it to the predefined folder (user doesn't know where it is) right after the user click OK button on Open File Dialog. Something like of importing a file to the application. I do it in the following way:
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
dlg.Filter = "Text documents (.txt)|*.txt";
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
string filename = dlg.SafeFileName;
System.IO.File.Copy(filename, #"E:\TestFolder\" + filename);
MessageBox.Show("File " + filename + " saved");
}
Is there a standard way to check if the file already exists before trying to save it and if it is really saved after saving it?
Look at System.File.Exists that should be able to tell you what you need to know.
The System.IO.File.Exists method returns true if a file at the given path exists, so you could use it to check both before and after your copy operation.
Use the SaveFileDialog (Microsoft.Win32). If you try to save over a file that already exists it will prompt you to make sure you want to save over that file. This doesn'y actually save it though, all it will do is provide the name and location of the file you want to create/save over. After you use the SaveFileDialog to select the file you then need to do the work of saving the file.
