I am trying to place a new Menuitem in Explorer context menu and I cannot get it to work.
I am not getting any exceptions or error messages and I've set breakpoints and they're not being hit. And I've searched the registry and it's not there. What am I doing wrong?
private const string MenuName = "Folder\\shell\\NewMenuOption";
private const string Command = "Folder\\shell\\NewMenuOption\\command";
private void Form1_Shown(object sender, EventArgs e)
{
using(var folder = new FolderBrowserDialog())
{
if(folder.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Properties.Settings.Default.ArchivePath = folder.SelectedPath;
Properties.Settings.Default.Save();
RegistryKey regmenu = null;
RegistryKey regcmd = null;
try
{
regmenu = Registry.ClassesRoot.CreateSubKey(MenuName);
if (regmenu != null)
regmenu.SetValue("", "Archive");
regcmd = Registry.ClassesRoot.CreateSubKey(Command);
if (regcmd != null)
regcmd.SetValue("", Environment.CurrentDirectory + #"\Archiver.exe");
}
catch (Exception ex)
{
MessageBox.Show(this, ex.ToString());
}
finally
{
if (regmenu != null)
regmenu.Close();
if (regcmd != null)
regcmd.Close();
}
}
else
{
if(MessageBox.Show("In order to use Archiver, you must first specify where your archive is. Do you want to continue?", "Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1) == System.Windows.Forms.DialogResult.Yes)
{
Application.Restart();
}
else
{
this.Dispose(true);
}
}
}
}
Run your app as admin.
Making changes to the register may require admin rights.

I am having a problem with a with a code that I used for my C# application. When I click on the browse button and select the file dialogue box opens twice.
private void txt_location_TextChanged(object sender, EventArgs e)
{
string folderPath = "";
FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog();
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
folderPath = folderBrowserDialog1.SelectedPath;
}
}
private void Button21_Click(object sender, EventArgs e)
{
using(var fbd = new FolderBrowserDialog()) {
DialogResult result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath)) {
selectedPath = fbd.SelectedPath;
txt_location.Text = selectedPath;
}
}
}
private void bunifuThinButton21_Click_1(object sender, EventArgs e)
{
System.IO.StreamWriter file;
bool isvalid = ValidateInputs();
try {
file = new System.IO.StreamWriter(selectedPath + # "\dred.txt");
catch (Exception ex) {
MessageBox.Show("Please, Select valid Path..");
return;
}
try {
if (isvalid) {
WriteLines(file);
}
}
catch (Exception ex2) {
MessageBox.Show(ex2.Message);
}
finally {
file.Close();
}
}
}
Obviously, it is only meant to open once to enable me to read the selected file. This works, but only once I have selected the file twice.
Thanks in advance for your help.
You have FolderBrowserDialog being instantiated and shown on two different events:
txt_location_TextChanged
and
Button21_Click
You're having two popups because each one is firing once separately.
You should probably remove the event txt_location_TextChanged entirely unless you need it for another thing that isn't popping the FolderBrowserDialog again.
When closing Form containing a WebBrowser control with a Pdf document open in the webbrowser, the form takes some 10 seconds to close. I tracked the issue down to Dispose method of the webbrowser.

Adobe has done something wrong in the latest version of Acrobat Reader DC (15.023.20056).
If you uncheck option Enable Protected Mode at startup in Edit -> Preferences -> Security (Enhanced), everything will be back to normal.
On my case it is not a solution.

Hello all i have managed to make a basic program that will do a update for me but one thing i want to try and do when the update form is open to close the main form then restart program when the update is finished but have no idea how to do this
this is the code i have currently
namespace update_test
{
public partial class Form1 : Form
{
// folder calls needed
string updatepath = Path.Combine( Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "updatetest");

then i have another form attached to this application called
elfenliedprograms.cs
witch contains this code
namespace update_test
{

{
InitializeComponent();
}

finally
{
if (reader != null)
reader.Close();
}
Version applicationvershion = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version;

else if (dialogResult == DialogResult.No)
{
//do something else
}
else
{

}
}
}
so basically once the update triggers there is a update it will call elfenliedprograms.cs but it will not shut down the main form if i do that it will shut the whole process down and im not sure how to go about making it download then restart app so all new stuff is updated it has taken me a good 4 months just to get this working the way i want not very good when it comes to updating a aplication so i would need help on this part sorry to be a pain and ask
thank you for
I have this code that works fine when I call it from within the form, however, when I call the same from the Parent it runs through the code without results:
public void hideHelp()
{
//Check in db if panel1 is visible
SqlCeCommand checkHelp = new SqlCeCommand("Select Show_Help from Options where Opt_Id = 1", this.optionsTableAdapter.Connection);
if (this.optionsTableAdapter.Connection.State == ConnectionState.Closed)
{ this.optionsTableAdapter.Connection.Open(); }
try
{
bool showHelp = (bool)(checkHelp.ExecuteScalar());
this.panel1.Visible = showHelp;
this.Refresh();
}
catch (Exception ex) { MessageBox.Show(ex.Message); }
}
On Main form I have a toggle button with the following code:
private void tglHelp_Click(object sender, EventArgs e)
{
if (tglHelp.ToggleState.ToString() == "On")
{
HRDataSet.OptionsRow updateHelp = hRDataSet.Options.FindByOpt_Id(1);
try
{
updateHelp.Show_Help = true;
this.optionsTableAdapter.Update(this.hRDataSet);
Form activeChild = this.ActiveMdiChild;
if (activeChild.Name == "frmAddEmployees")
{
frmAddEmployees chForm = new frmAddEmployees();
chForm.MdiParent = this;
chForm.hideHelp();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message, Application.ProductName);
}
tglHelp.Text = "Help Panel \nOFF";
}
Any ideas?
In this piece of code
if (activeChild.Name == "frmAddEmployees")
{
frmAddEmployees chForm = new frmAddEmployees();
chForm.MdiParent = this;
chForm.hideHelp();
}
you open another frmAddEmployees and add to the MDI, but you don't show it.
If your intent was to call the code in the current frmAddEmployees identified by the activeChild you should use something like this
if (activeChild.Name == "frmAddEmployees")
{
((frmAddEmployees)activeChild).hideHelp();
}
