Simple Password enter in a WPF C# app

[Sarkhan Vol]

trying to create a simple password entry into a Window(WPF) which is called MainSite but can't seem to get the code working

<Window x:Class="Password_protection.Password"
	    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	    Title="Password" Height="350" Width="525">
    <Grid>
	    <TextBox Height="28" HorizontalAlignment="Left" Margin="230,102,0,0" Name="passwordBox1" VerticalAlignment="Top" Width="130" TextChanged="OnPropertyChanged" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" />
	    <Label Content="Enter Password" Height="28" HorizontalAlignment="Left" Margin="130,102,0,0" Name="label1" VerticalAlignment="Top" Width="94" />
	    <Button Content="Enter Site" Height="23" HorizontalAlignment="Left" Margin="416,276,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
	    <Button Content="Cancel" Height="23" HorizontalAlignment="Left" Margin="325,276,0,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button2_Click" />
    </Grid>
</Window>

Can you be any more precise than "it doesn't work"? Does it compile? If not, what are the compiler errors? If it compiles and runs, how is not behaving to way you want?

Your buttons point to button1_Click and button2_Click events but your methods are called Enter and Cancel

<Window x:Class="Password_protection.Password"
		xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
		xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

		<TextBox Height="28" HorizontalAlignment="Left" Margin="230,102,0,0" Name="passwordBox1" VerticalAlignment="Top" Width="130" TextChanged="OnPropertyChanged" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" />
		<Label Content="Enter Password" Height="28" HorizontalAlignment="Left" Margin="130,102,0,0" Name="label1" VerticalAlignment="Top" Width="94" />
		<Button Content="Enter Site" Height="23" HorizontalAlignment="Left" Margin="416,276,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="Enter" />
		<Button Content="Cancel" Height="23" HorizontalAlignment="Left" Margin="325,276,0,0" Name="button2" VerticalAlignment="Top" Width="75" Click="Cancel" />
	</Grid>
</Window>
[/CODE]

don't know why it says button1_Click but the program complies with this error (Error 1 Operator '!=' cannot be applied to operands of type 'System.Windows.Controls.TextBox' and 'string')

but i think my logic might be wrong when the enduser enters the right static password which is Password then it should allow access to the MainSite.xaml if nothing is entered then a messageBox displays nothing is entered, if the wrong password is enter,then again message to try again. but as i click the enter site button it just goes to the MainSite.xaml. also none of the messageBoxs are working.

If there are any compilation errors then the code does not compile. If you ask Visual Studio to run the "last successful build" it will run just that, the last successful build - not the build of your current code, because your current code doesn't build.

This compilation error probably points to

passwordBox1 != password[/CODE]

which is illegal because passwordBox1 is a TextBox and password is a String; they cannot be compared directly. You want to compare its Text property, i.e.

[CODE]passwordBox1.Text != password[/CODE]

.

thank you very much that's sorted the problem.

c# how do you change the inputted text in the textBox to ***** to hide the password entered i've tried

passwordBox1.PasswordChar = '*';
[/CODE]

but PasswordChar throws an Error 1 'System.Windows.Controls.TextBox' does not contain a definition for 'PasswordChar' and no extension method 'PasswordChar' accepting a first argument of type 'System.Windows.Contrs.TextBox' could be found (are you missing a using directive or an assembly reference?)

i've tried these three lines of code

[CODE]
((TextBox)this.passwordBox1.TextBoxElement.TextBoxItem.HostedControl).UseSystemPasswordChar = true;
passwordBox1.UseSystemPasswordChar = true;
passwordBox1.PasswordChar = '*';
[/CODE]

none seem to do the job

Are you a VB coder? :D

No offense intended.

I would rather do:

string passGiven = passwordBox1.Text;

if(!passGiven.Equals(password))

{

...

Also, to test if the pass is empty

if(string.IsNullOrWhiteSpace(passGiven))

{

...

started off using VB and switched to C# because VB is well just crap :p
