    <p>If you don't need to change the filename, but only the folder where this file is saved, then you can use the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.folderbrowserdialog.aspx" rel="nofollow">FolderBrowserDialog</a> to ask just the folder where the file will be saved</p> <pre><code>private void button2_Click(object sender, System.EventArgs e) { FolderBrowserDialog fbd = new FolderBrowserDialog(); fbd.Description = "Select the destination folder"; fbd.ShowNewFolderButton = true; fbd.RootFolder = Environment.SpecialFolder.Personal; if( fbd.ShowDialog() == DialogResult.OK ) { string folderName = fbd.SelectedPath; .... the rest of your excel export code ..... // Pass the full path to the SaveAs method string fullPathName = Path.Combine(folderName, "csharp.net-informations.xls"); xlWorkBook.SaveAs(fullPathName, .....); ..... MessageBox.Show("Excel file created , you can find the file in: " + fullPathName); } </code></pre> <p>If you need to change also the file name, then you need to use a SaveFileDialog instance. </p> <pre><code> SaveFileDialog sfd = new SaveFileDialog(); sfd.Filter = "Excel files (*.xls)|*.xls|All files (*.*)|*.*" ; sfd.FilterIndex = 1 ; sfd.RestoreDirectory = true ; sfd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Personal); if(sfd.ShowDialog() == DialogResult.OK) { if(sfd.FileName.Length &gt; 0) { ... the rest of your excel code here .... // sfd.FileName already contains the full path so xlWorkBook.SaveAs(sfd.FileName, .....); } } else { if(MessageBox.Show("Are you sure you want to quit without saving?", "Quitting", MessageBoxButtons.YesNo) == DialogResult.No) { // This important to stop the Form to close if this button is the Cancel/AcceptButton // or its property DialogResult is not DialogResult.None this.DialogResult = DialogResult.None; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
