a web browser is not a good fit b/c it shows stuff in a pretty defined way. Just use labels to show text, and pictureboxes to show a picture. Bitmap.FromFile will load the image from that file for you

Hi all,

I've created a user-control, which resides in library of other controls I use in my application. The control has two or three textboxes and some drawn graphics. I've put this control in my main application and it basically works fine.

Next I have a class, and I create an instance which stores my data and I serialise this class to file for use later on. The user-control is used to change the values in this object and I do that using an event which is fired when the TextChanged event occurs. What makes it more complicated is I can have multiple instances of the class which I need to switch between and the user-control needs to display the data in the textboxes for the objectI've selected.

My problems see to start when I reload my serialized file or switch between the objects.

So for example, when I initialise the control I do:

usercontrol.textboxA = X.GetParamA;
usercontrol.textboxB = X.GetParamB;

When I switch between say object X and Y I do

usercontrol.textboxA = Y.GetParamA; // This can cause issues as TextChanged is called
usercontrol.textboxB = Y.GetParamB;

When the user changes a value in the textbox I fire the event which is caught in the form containing the user-control I do:

// Get selected object X or Y in this case

Y.GetParamA = usercontrol.textboxA;
Y.GetParamB = usercontrol.textboxB;

This really doesn't feel like the right way to tackle this and I fear my design is off. I though of passing in a reference to my objects or maybe there is a better way to use the events...

Any suggestions would be great.

Thanks

Looks ok to me, remember most of your work revolves changing data from one format to another and vice versa.

Hi guys.

How can i execute or fire an event, by example the Validated event for a textbox control from another control like a button?

Example:

I have the following code for the Hello textbox Validated event:

private void Hello_Validated(object sender, EventArgs e)
{
    MessageBox.Show("Hello guys");
}

I want to fire that event, the Validated event from another control like a button, so i can show the message "Hello Guys"
by clicking a button.

Thanks for your time...

Regards...

private void Button_Click(object sender, EventArgs e)
{
  Hello_Validated(null, EventArgs.Empty);
}

I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

Just call Hello_Validated function from the part of the code you wish.

Can't you at least be polite when you criticize someone? At least the code is reasonably formatted if not in pre blocks.

Have you checked spam folders etc? Another alternative is have you tried using a service such as Gmail to see whether that works?

I'm assuming that if there's no exception thrown then the email was sent successfully but may have been lost in transit so to speak.

Check the smtp server. It may be sitting there undeliverable and retrying the send.

My guess is the server filters and rejects logging in and sending mail from random applications.

See: http://www.eggheadcafe.com/articles/20030316.asp*[^]
