Open file dialog freezes the program when I try to use it
0
I am using visual studio 2017 to create a windows form application, which I am trying to use OpenFileDialog to load an XML file.
when I first created the program everything works fine but after working and testing my code the application freezes when I launch the event to show the dialog.
I had this problem before where I was using Visual Studio 2015 and I could not find a solution.
public Form1()
{
InitializeComponent();
}
private void btnLoad_Click(object sender, EventArgs e)
{
if (ofdLoadXMLFile.ShowDialog() == DialogResult.OK)
{
string fileName = ofdLoadXMLFile.SafeFileName;
MessageBox.Show(fileName);
lblFileName.Text = fileName;
File.Copy(ofdLoadXMLFile.FileName, fileName);
XmlDocument document = new XmlDocument();
string _byteOrderMarkUtf8 = Encoding.UTF8.GetString(Encoding.UTF8.GetPreamble());
document.LoadXml(fileName.ToString());
string jsonText = JsonConvert.SerializeXmlNode(document);
string result = document.ToString();
File.WriteAllText(@"C:UsersConnect To AllDesktopresult.json", jsonText);
}
can anyone help with this? is there anything that I can do?
Thank you

Use breakpoints and know which line is causing the freeze.

So you still have the problem you had before. OpenFileDialog and friends are somewhat risky components, they cause all of the shell extensions to get loaded into your process. Programmer machines tends to have a lot of them, not always of the best quality. One possibly quick way to escape is to change the jitter forcing so 32-bit extensions can't work. Project > Properties > Build tab, untick "Prefer 32-bit". SysInternals' Autoruns utility is a decent way to locate and disable the bad one.
