C# Path.GetFileName() as well as OpenFileDialog.SafeFileName cuts off the underscores in the filename

In my company it is common to name files in the following manner: 210808_Filename.extension
Unfortunately both of these ways to get the filename failed: Path.GetFileName() and OpenFileDialog.SafeFileName. In the path itself the underscores exist, but in the filename they get removed.
private void btnOpenFile_Click(object sender, RoutedEventArgs e)
{
string strCheck = "";
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.ShowDialog();
strConfigPath1 = openFileDialog1.FileName;
if (strConfigPath1.Length > 6)
{
strCheck = strConfigPath1.Substring(strConfigPath1.Length - 6);
}
if (strConfigPath1 == "" || strCheck != ".gcode")
{
MessageBox.Show("Selected file has to be a GCode file.");
}
else
{
lblSelectedDocument.Content = System.IO.Path.GetFileName(string);
}
}
I know it may not be a well programmed code due to the fact I am bloody new to programming. Sorry for that.

Here's a straightforward way to set the contents of the label, based on the file that the user selects:
private void btnOpenFile_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog openFileDialog = new OpenFileDialog();
if (openFileDialog.ShowDialog() == true)
{
string chosenFilename = openFileDialog.FileName;
if (Path.GetExtension(chosenFilename).ToLower() == ".gcode")
{
lblSelectedDocument.Content = "Valid file. You selected " + chosenFilename;
}
else
{
lblSelectedDocument.Content = "Invalid file - not a .GCODE file. You selected " + chosenFilename;
}
}
else
{
lblSelectedDocument.Content = "You did not select a file.";
}
}
If the user doesn't select a file, we just set the label to be You did not select a file.
If the user did select a file, we check if the file extension is our intended extension. The check is case-insensitive, so .GCODE, .GcOdE, .gcode (etc) will all work. If the user selected a gcode file, the label says the filename is valid and shows the filename.
If the file extension doesn't match, the user must have selected an invalid file. When this occurs we tell them the filename is invalid and show the filename.

How can I update image in listview in gridview format?

how can i update image in listview in gridview formate using folder path in asp.net in c#?
protected void UpdateButton_Click(object sender, EventArgs e)
{
TextBox ApplicantIdTextBox = (TextBox)RadListView8.FindControl("ApplicantIdTextBox");
FileUpload photoTextBox = (FileUpload)RadListView8.FindControl("photoTextBox");
string fileName1 = Path.GetExtension(ApplicantIdTextBox + photoTextBox.FileName);
string fileSavePath = Server.MapPath("ImageStorage/" + fileName1);
tblPersonalInfo pi = new tblPersonalInfo();
pi.photo = fileName1;
photoTextBox.SaveAs(fileSavePath);
dbcontext.AddTotblPersonalInfoes(pi);
dbcontext.SaveChanges();
}
But it show me error...What can i do?
Server Error in '/HrPayRoll' Application.
Object reference not set to an instance of an object.

I'd rewrite it something like this and then run it in debug mode and see what line the error is on. You were trying to use applicantIdTextBox as a string, although I would have thought that would give a different error:
protected void UpdateButton_Click(object sender, EventArgs e)
{
TextBox applicantIdTextBox = RadListView8.FindControl("ApplicantIdTextBox") as TextBox;
FileUpload photoTextBox = RadListView8.FindControl("photoTextBox") as FileUpload;
if ((applicantIdTextBox != null) && (photoTextBox != null))
{
string fileName = Path.GetExtension(applicantIdTextBox.Text + photoTextBox.FileName);
string fileSavePath = Server.MapPath("ImageStorage/" + fileName);
tblPersonalInfo personalInfo = new tblPersonalInfo();
personalInfo.photo = fileName;
photoTextBox.SaveAs(fileSavePath);
dbcontext.AddTotblPersonalInfoes(personalInfo);
dbcontext.SaveChanges();
}
}

Word Add-In Ribbon

I created an Office Add-In project and I added ribbon menu for application. When I build my project word document have my ribbon there is no problem.
How can I save the active document as a file using StreamReader when clicking on a button from the ribbon menu using the button click event below?
private void btnsavefile_Click(object sender, RibbonControlEventArgs e)
{
//Getting FileStream here.
}

I found the following solution in Stack Overflow. Hopefully it is relevant to you.
Serialize current ActiveDocument from office 2007 add-in
Personally, I have done the same when I was dealing with this scenario. I have saved a copy of the file to the temporary location and pushed the copy to the server. In this case, the active document stays as is.
Excel.Workbook xlb = Globals.ThisAddIn.Application.ActiveWorkbook;
xlb.SaveCopyAs(filePath);
Hope this helps!

void Application_DocumentBeforeClose(Word.Document document, ref bool Cancel)
{
try
{
string filePath = this.Application.ActiveDocument.FullName.ToString();
string fileName = this.Application.ActiveDocument.Name;
//dialogFilePath = filePath;
dialogFileName = fileName;
string tempFile;
string tempPath;
if (true)
{
var confirmResult = System.Windows.Forms.MessageBox.Show("Are you sure to save this document ??",
"Confirm Save!!",
System.Windows.Forms.MessageBoxButtons.YesNo);
if (confirmResult == System.Windows.Forms.DialogResult.Yes)
{
//document.Save();
var iPersistFile = (IPersistFile)document;
iPersistFile.Save(tempPath, false);
//Do some action here
}
Word._Document wDocument = Application.Documents[fileName] as Word._Document;
//wDocument.Close(Word.WdSaveOptions.wdDoNotSaveChanges);
ThisAddIn.doc.Close(Word.WdSaveOptions.wdDoNotSaveChanges);
}
}
catch (Exception exception)
{
}
}

WPF Save DialogBox (for windows 64)

This is similar to older posts on this site but I keep getting an error message. I want to create a button in C # WPF that opens a dialogbox and saves a text file to be read at a later date. This code works for windows 32, but crashes on windows 64. How can I change this code to get it to work on both systems? I am a beginner at programming.
Microsoft.Win32.SaveFileDialog saveFile = new Microsoft.Win32.SaveFileDialog(); //throws error message here
private void savebutton_Click(object sender, RoutedEventArgs e)
{
saveFile.FileName = Class1.stringjobnum;
saveFile.Filter = "CCurtain (*.cur)|*.cur";
saveFile.FilterIndex = 2;
saveFile.InitialDirectory = "T:\\Tank Baffle Curtain Calculator\\SavedTanks";
saveFile.OverwritePrompt = true;
bool? result = saveFile.ShowDialog();
if (result.HasValue && result.Value)
{
clsSaveFile.s_FilePath = saveFile.FileName;
int iDotLoc = clsSaveFile.s_FilePath.LastIndexOf('.');
string strExtTest = clsSaveFile.s_FilePath.Substring(iDotLoc);
if (strExtTest != ".cur")
clsSaveFile.s_FilePath += ".cur";
FileInfo sourceFile = new FileInfo(clsSaveFile.s_FilePath);
clsSaveFile.saveFile();
}
}

You're setting an invalid FilterIndex, that might have something to do with it.
There is no 2nd filter in the filter string as written:
"CCurtain (*.cur)|*.cur"
Try setting the FilterIndex to 1 or adding another filter to the string.

You should try adding a catch around the statement to get a better idea as to what is going on.
try
{
code here
}
catch (Exception ex)
{
ex.message contains the info
}
Also, check for null:
bool? result = saveFile.ShowDialog();
if (result != null && (result.HasValue && result.Value))
{
// code
}

I would create the dialogbox IN the event. And you don't have two different filters.
private void savebutton_Click(object sender, RoutedEventArgs e)
{
Microsoft.Win32.SaveFileDialog saveFile = new Microsoft.Win32.SaveFileDialog();
saveFile.FileName = Class1.stringjobnum;
saveFile.Filter = "CCurtain|*.cur";;
saveFile.FilterIndex = 1;
saveFile.InitialDirectory = "T:\\Tank Baffle Curtain Calculator\\SavedTanks";
saveFile.OverwritePrompt = true;
// Show open file dialog box
Nullable<bool> result = saveFile.ShowDialog();
// Process open file dialog box results
if (result == true)
{
string filename = saveFile.FileName;
// are you sure you need to check the extension.
// if so extension is a a fileinfo property
}

C# WinForms - Multiselect not working on OpenFileDialog & Listbox

Hey Everyone,
Sorry to bother you with this, but I'm having an issue with selecting multiple xlsx files through a file browser window in a winforms application when debugging and can't figure out what I did wrong.
Problem: I set Multiselect=true under the OpenFileDialog but I still cannot select more than one file.
What do I need to change to get the multiSelect feature to work?
Do I need to add anything under sourceFileOpenFileDialog method?
Do I need to add anything under listBoxSourceFiles_SelectedIndexChanged method to get the filenames to load correclty in the listbox?
// When the user clicks on Select Files Button, this happens
private void sourceFiles_Click(object sender, EventArgs e)
{
Stream myStream;
int i = 0;
OpenFileDialog sourceFileOpenFileDialog = new OpenFileDialog();
this.sourceFileOpenFileDialog.InitialDirectory = "i:\\CommissisionReconciliation\\Review\\";
this.sourceFileOpenFileDialog.Filter = "Excel Files (*.xls;*.xlsx;)|*.xls;*.xlsx;|" + "All Files (*.*)|*.*";
this.sourceFileOpenFileDialog.FilterIndex = 2;
this.sourceFileOpenFileDialog.RestoreDirectory = true;
this.sourceFileOpenFileDialog.Multiselect = true;
this.sourceFileOpenFileDialog.Title = "Please Select Excel Source File(s) for Consolidation";
if (sourceFileOpenFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = sourceFileOpenFileDialog.OpenFile()) != null)
{
using (myStream)
{
foreach (string FileName in sourceFileOpenFileDialog.FileNames)
{
sourceFileOpenFileDialog.FileNames[i] = FileName;
listBoxSourceFiles.Items.Add(FileName);
Log("Source Files: " + sourceFileOpenFileDialog.FileNames[i]);
i++;
}
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
//method for the listbox. Do I need anything here?
private void listBoxSourceFiles_SelectedIndexChanged(object sender, EventArgs e)
{
}
//method for the sourceFileOpenFileDialog. Do I need anything here?
private void sourceFileOpenFileDialog_FileOk(object sender, CancelEventArgs e)
{
}
I updated the code to reflect sourceFileOpenFileDialog and the MultiSelect or Title doesn't work... Perhaps I'm referencing the onfiledialog wrong? is this the proper prefix to use?
Thanks for looking!

You are using two OpenFileDialogs. You display sourceFilesList but you initialized sourceFileOpenFileDialog. Using consistent naming rules religiously is a great way to avoid bugs like these btw.
Next problem, what is OpenFile() supposed to do when you selected more than one file? What is myStream actually used for?

You are setting up sourceFileOpenFileDialog but then use sourceFileList!!! Make up your mind and only use one.

Fixed the non-working MultiSelect by:
Updating the code to only use one variable sourceFileOpenFileDialog throughout the method and the MultiSelect or Title didnt work...
Removing all references to myStream. myStream was used in an example which i based my code off but i took it out and the multiSelect works!
Here's the working code:
// When the user clicks on Select Files Button, this happens
private void sourceFiles_Click(object sender, EventArgs e)
{
Stream myStream;
int i = 0;
OpenFileDialog sourceFileOpenFileDialog = new OpenFileDialog();
this.sourceFileOpenFileDialog.InitialDirectory = "i:\\CommissisionReconciliation\\Review\\";
this.sourceFileOpenFileDialog.Filter = "Excel Files (*.xls;*.xlsx;)|*.xls;*.xlsx;|" + "All Files (*.*)|*.*";
this.sourceFileOpenFileDialog.FilterIndex = 2;
this.sourceFileOpenFileDialog.RestoreDirectory = true;
this.sourceFileOpenFileDialog.Multiselect = true;
this.sourceFileOpenFileDialog.Title = "Please Select Excel Source File(s) for Consolidation";
if (sourceFileOpenFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
string tempFolder = System.IO.Path.GetTempPath();
foreach (string FileName in this.sourceFileOpenFileDialog.FileNames)
{
this.sourceFileOpenFileDialog.FileNames[i] = FileName;
listBoxSourceFiles.Items.Add(FileName);
Log("Source Files: " + sourceFileOpenFileDialog.FileNames[i]);
i++;
System.IO.File.Copy(FileName, tempFolder + #"\" + FileName);
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
//method for the listbox. Do I need anything here?
private void listBoxSourceFiles_SelectedIndexChanged(object sender, EventArgs e)
{
}
//method for the sourceFileOpenFileDialog. Do I need anything here?
private void sourceFileOpenFileDialog_FileOk(object sender, CancelEventArgs e)
{
}
