Folder Dialog return to dialog if criteria not met

I'm using the Ookii Vista folder dialog for ease of use, and I have this code going on which is called from a button:
using System;
using System.IO;
using System.Linq;
using System.Windows.Forms;
using Ookii.Dialogs;
private string LoadDirectories()
{
VistaFolderBrowserDialog fbd = new VistaFolderBrowserDialog();
if (fbd.ShowDialog() == DialogResult.OK && fbd.SelectedPath.Contains("U000"))
{
return fbd.SelectedPath;
}
else
{
MessageBox.Show("Folder must be root assembly, which has U000 in name");
}
return string.Empty;
}
Currently, if the user does not pick a folder with U000 in the name, the dialog will close, but I want it to stay open until user either cancels or sets the correct folder path. I can't find this anywhere.

A simple realization of your needs (Add a while):
Used nuget: Ookii.Dialogs.Wpf
private string LoadDirectories()
{
VistaFolderBrowserDialog fbd = new VistaFolderBrowserDialog();
while (true)
{
if (fbd.ShowDialog() == false)
{
break;
}
else if (fbd.SelectedPath.Contains("U000"))
{
return fbd.SelectedPath;
}
else
{
MessageBox.Show("Folder must be root assembly, which has U000 in name");
}
}
return string.Empty;
}
output：

Adding Page Numbers

I haven't really written anything outside of Powershell in a long time, and I know this is ugly, but I can't seem to figure out why my new PDF is not adding the page numbers. I pulled the example from this itext kb.
I tried to make this basic app so people in the office could add the page numbers to PDF's. Here's what I have so far. It will create the new PDF (duplicate of the original), but it's not adding the page numbers.
Basically they use button1 to find their PDF via the Windows File Explorer dialog. It just stores the filename in a textbox. The second button is the "save" and should take the src file and make a copy of the src with only adding the page number at the bottom of the file (or anywhere at this point).

textBox1.Text = file;

Console.WriteLine(size); // <-- Shows file size in debugging mode.

{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
string SRC = textBox1.Text;
string DEST = saveFileDialog1.FileName;
FileInfo file = new FileInfo(DEST);
file.Directory.Create();
PdfDocument pdfDoc = new PdfDocument(new PdfReader(SRC), new PdfWriter(DEST));
Document doc = new Document(pdfDoc);
int numberOfPages = pdfDoc.GetNumberOfPages();
for (int i = 1; i <= numberOfPages; i++)
{
// Write aligned text to the specified by parameters point
doc.ShowTextAligned(new Paragraph("page " + i + " of " + numberOfPages),559, 806, i, TextAlignment.CENTER, VerticalAlignment.TOP, 0);
}
doc.Close();
}

I'm a dumb dumb. The x,y coordinates were off as the value 812 for the height is off the page.

windows explorer shell integration and bit more?

I have registered a program in windows explorer right click menu using this link. .NET-Shell-Extension, It works fine. But my problem is I want to target XML file, If I right click on that file it will load that XML file and open fileDialog to choose folder and create folder and sub-folder according to the structure of the XML file. It looks fine when I tasted it on shell server. I tried to register with this following code but its not appearing when I click on any XML file.
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;
using SharpShell.Attributes;
using SharpShell.SharpContextMenu;
using System.Xml;
namespace ClassLibrary1
{
[ComVisible(true)]
[COMServerAssociation(AssociationType.ClassOfExtension, ".xml")]
public class Class1 : SharpContextMenu
{
protected override bool CanShowMenu()
{
return true;
}
protected override ContextMenuStrip CreateMenu()
{
var menu = new ContextMenuStrip();
var createFolder = new ToolStripMenuItem
{
Text = "Create Folder",
};
createFolder.Click += (sender, args) => myFunction();
menu.Items.Add(createFolder);
return menu;
}
private void myFunction()
{
var ofd = new OpenFileDialog();
foreach (var filePath in SelectedItemPaths)
{
if (ofd.ShowDialog() != DialogResult.Cancel)
{
string fullPath = ofd.FileName;
using (XmlTextReader reader = new XmlTextReader(fullPath))
{
var basePath = filePath + "/";
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
var baseDirPath = Path.Combine(basePath + reader.Name);
Directory.CreateDirectory(baseDirPath);
break;
case XmlNodeType.Text:
Directory.CreateDirectory(basePath + reader.Name + "/" + reader.Value);
break;
}
}
}
}
}
}
}

C# program for automating excel with before close event handler not saving edited excel file

I wanted to avoid Excel ole calls through my c++ code to launch excel. I also wanted to wait for excel to be closed before proceeding. For that I implemented following C# program and I use system call to execute it. It works but any changes I make to the excel are not getting saved. I am not sure whats happening.
Can you please help.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Excel = Microsoft.Office.Interop.Excel;
using System.IO;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace excelHandler
{
class Program
{
private static bool isClosed = false;
private static void app_WorkbookBeforeClose(Excel.Workbook wb, ref bool cancel)
{
if (!wb.Saved)
{
DialogResult result = MessageBox.Show("Do you want to save the " +
"changes you made to " + wb.FullName + "?", "Blizzard Excel",
MessageBoxButtons.YesNoCancel,MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1,
MessageBoxOptions.DefaultDesktopOnly);
switch (result)
{
case DialogResult.Yes:
wb.Save();
break;
case DialogResult.Cancel:
cancel = true;
break;
// The following code ensures that the default Save File
// dialog is not displayed.
case DialogResult.No:
wb.Saved = true;
break;
}
}
isClosed = !cancel;
// wb.Parent
}
static int Main(string[] args)
{
int returnValue = 0;
if (args.Length != 1)
{
Console.WriteLine("-E- excelHandler takes single XLXS as input");
return -1;
}
string inputFile = args[0];
if (!File.Exists(inputFile))
{
Console.WriteLine("-E- Input File doesn't exist: {0}", inputFile);
return -1;
}
Excel.Application xlApp = new Excel.Application();
try
{
Excel.Workbook xlWorkBook = xlApp.Workbooks.Open(inputFile);
xlApp.Visible = true;
Excel.AppEvents_WorkbookBeforeCloseEventHandler Event_BeforeBookClose;
Event_BeforeBookClose = new Excel.AppEvents_WorkbookBeforeCloseEventHandler(app_WorkbookBeforeClose);
xlApp.WorkbookBeforeClose += Event_BeforeBookClose;
// ||
while (!isClosed)
{
System.Threading.Thread.Sleep(300);
}
//xlWorkBook.Close(true);
Marshal.ReleaseComObject(xlWorkBook);
}
catch
{
}
finally
{
xlApp.Quit();
Marshal.ReleaseComObject(xlApp);
}
return returnValue;
}
}
}

I found the issue. It was with MessageBoxOptions.DefaultDesktopOnly option in
DialogResult result = MessageBox.Show("Do you want to save the " +
"changes you made to " + wb.FullName + "?", "Blizzard Excel",
MessageBoxButtons.YesNoCancel,MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1,
MessageBoxOptions.DefaultDesktopOnly);
I changed it to following to get it working.
NativeWindow nw = new System.Windows.Forms.NativeWindow();
nw.AssignHandle(new IntPtr(wb.Parent.Hwnd));
DialogResult result = MessageBox.Show(nw,"Do you want to save the " +
"changes you made to " + wb.FullName + "?", "Blizzard Excel",
MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1);
I am still not sure what was wrong with my initial code.

axShockwaveFlash_FSCommand not responding on some machines

I have created a C sharp project in which i have added a ShockwaveFlashObject to play my swf file.
The problem i am facing is when i create an installer for my project it works correctly on my machine on installation, but on my laptop the swf loads correctly but doesn't respond to the _FSCommand. I cannot use a try and catch block as it is not entering the FSCommand handle. Do i need to bundle something with my installation?
The laptop i am using is brand new and i wanted it that way so that i know what all stuff is needed for things to work correctly so that i can add prerequisites to my installer.
Also idk if this information is of any use but I am using advanced installer to build and exe for my project.
PS i have added things like the below code to know if FSCommand gets executed.
MessageBox.Show("step 1/2/3");
Here is the entire code.

Is flash player ActiveX control installed on your laptop? You have to install it, otherwise there's nothing that can play your .swf file.
