The Button1_EnableChanged event doesn't fire until Button1.Enabled = true; executes. Hence, Button1.Enabled = true; must go into another method, such as, for example, the method that detects the change that makes it appropriate to enable the button.
As an example, if I have a routine that has a TextBox1_TextChanged event that evaluates the Text property of TextBox1, and determines that its new value warrants enabling Button1, it does so by setting its Enabled property to True.

I use RouteCollection with FriendlyUrlSettings to remove aspx from being shown... so now every time someone access my site, instead of display www.mysite.com/login.aspx , it will display www.mysite.com/login
But I have a problem where an old app needs to access a page, and it's already hard-coded inside the app to access www.mysite.com/service/AuthenticateUser.aspx page. But because of the friendlyurl, the app doesn't work.
So I added this line
routes.Ignore("Service/AuthenticateUser.aspx");
but it doesn't seem to do anything. Every time I access the page Service/AuthenticateUser.aspx , it will still redirect me to Service/AuthenticateUser only

How about asking this in the ASP.NET forum as it has nothing to do with C#.
|
|
|
|
|
err... why is this a asp.net question? As per my understanding, the codes that handles the ignoring of specific file or folder needs to be written in the back code (c#) in my case.
public static void RegisterRoutes(RouteCollection routes)
{
routes.RouteExistingFiles = false;
routes.Ignore("SERVICE/{*pathInfo}");
var settings = new FriendlyUrlSettings();
settings.AutoRedirectMode = RedirectMode.Permanent;
routes.EnableFriendlyUrls(settings);
}
the code above is what I did but still doesn't work

Because you're asking about the functionality of ASP.NET and/or possibly MVC routing.

Hello there. I am given a small xml script. How can I use that script to change the frame rate of this IP camera. Thanks for any input.
|
|
|
|
|
The question is not clear. Please explain what C# issues you are having problems with.
|
|
|
|

Well, I would say that you need to read some value from your XML file. It will either be an attribute or an element. Oh wait, it might be a set of values that you use to calculate the rate. If it is, you will have to read the values in and apply whatever calculation is appropriate. However, unless I'm greatly mistaken, IP cameras don't use framerates - they use bandwidth, and while you may be able to change the frame rate, the underlying bandwidth might not be able to cope.
As for actually choosing a frame rate and displaying your images then why not look at Aforge and set the DesiredFrameRate[^].

I have a textBox where i want to insert a string in a licence model (fdsf-dfss-fdfd-fdhd). I tried to select first 4 char and when I have 4 chars, is inserted "-". But it starts from the beginning when "-" is inserted after first 4 chars. This is how I tried:
private void textBox4_TextChanged(object sender, EventArgs e)
{
for (int i=0;i<=textBox4.Text.Length;i++)
{
while (textBox4.Text.Length == 4)
{
textBox4.Text += "-";
}
}
}
How can I make like after I have 4 chars and "-" is inserted, to be able to continue inserting the text after "-" ?

Change it to:
textBox4.Text += "-";
textBox4.SelectionStart = textBox4.Text.Length;
..in order to set the input cursor to the end of the text again.
Unrelated suggestion: Give your TextBoxes and all other controls a name that explains their purpose - in this case maybe "LicenceInput". That will make it much easier to read your code, even for yourself, after you haven't worked on it for a while 
edit: A MaskedTextBox might be the most convenient way to handle this. The input mask would be: 0000\-0000\-0000\-0000

it works, but after I insert another 4 characters, "-" is not inserted.

Please edit your original post and add your reworked code in a second code-block.

On second thought, the modulo operator-approach isn't really well suited here, because due to inserting the dashes, the length of the text won't be a multiple of 4 at the positions where the next dash should be inserted. I would recommend a MaskedTextBox instead with an input mask like 0000\-0000\-0000\-0000

is this a web app or windows app? If it is windows then you can use Masked Input and if it is web then you can use Jquery, don't need to hit server every time..

Is win form. I will try, thanks!
