Like Griff, I also recommend books over YouTube videos. This is a good, free PDF-book on programming in C# for beginners: Introduction to Programming with C# / Java Books[^]

It doesn't cover database, UI, and other advanced fields of programming but C# language constructs (e.g. LINQ) and the most important classes from the .NET framework (e.g. dictionaries). So it's not exactly helping you here with database programming but I assume you'll find it helpful nonetheless.

I didn't call you dumb and I didn't mean my message to sound like it. The only thing I'm saying is if you're asking a question here and you get an answer, it would be appreciated if you actually read that answer and follow the given advice before posting the next question about the same thing. If you have difficulties of any kind in making use of an answer you're free to ask for clarification - and I would have provided it.

This is the data in the list box, from a database

This is the data in the combo Box

(M)
(F)

I want to select a name in the listbox then when I proceed to select the gender from the comboBox the value I select must be added to the end of the name that is selected

example.

Carol Willis(F)

Any form of help will be appreciated

On 'selectedIndexChanged' event of combo box, get selected text from it and append it to selected text of Listbox
Note: There is no direct way to append text, you need to first remove selected name from listbox and then add new name with gender
-hope it helps

Thank You, will try it

A few comments:

1. consider the design of displaying the abbreviation for the gender at the end of the name. If you have a synchronized ComboBox/ListBox isn't it enough that your current choice in the ListBox exposes its gender value in ComboBox ?

2. Have you worked with DataBinding these Controls: that's the way to get them synchronized; in WinForms that does have a certain over-head: you may have to reset the binding state as the data type you bind to changes its internal values.

3. Consider using a Dictionary where the Keys are strings, and the Values are either strings or an Enum.

C#

public enum GenderType  // this is Thailand ...
     Indeterminate,
     Ambivalent,
     RefuseToState,
     Male,
     Female,
     Hermaphrodite,
     TransPreOpMToF,
     TransPreOpFToM,
     TransPostOpMToF,
     TransPostOpFToM,
     Eunuch,
     Alien
}

private Array EnumTypeValues { set; get; }
private BindingSource EnumBindingSource { set; get; }

public void SomeMethod(Type enumtype, ComboBox combo)
{
    EnumTypeValues = Enum.GetValues(enumtype);

    EnumBindingSource = new BindingSource();
    EnumBindingSource.DataSource = EnumTypeValues;
    combo.DataSource = EnumBindingSource;
    combo.DisplayMember = "Name";

    combo.SelectedValueChanged += ComboOnSelectedValueChanged;
}

// assuming you've called 'SomeMethod passing the Enum, and a reference to a ComboBox:
// SomeMethod(typeof(GenderType), comboBox1);


private void ComboOnSelectedValueChanged(object sender, EventArgs eventArgs)
{
    GenderType gType = (GenderType) comboBox1.SelectedValue;

    switch (gType)
    {
        case GenderType.Indeterminate: 
            // do something
            break;
        case GenderType.Male:
            // do something else
            break;
        case GenderType.Female:
            // do something else
            break;
        case GenderType.Ambivalent:
            // get Eddie Izzard out of here
            break;
        case GenderType.Alien:
            // call Area 51
            break;
        default:
            break;
    }
   // update other data-structures, or Controls ?
}

I want to develop an app that gets employee-data from the SharePoint - My Site Collection and I'd like to change their properties through webservice communication.

What is the best practice to get me going?

I'm searching for a sample of:
1. The webservice communication
2. A get function to retrieve info
3. A set function to set properties

If anyone has the experience and can help me with this, that would be gold. Thumbs Up | :thumbsup:

Hook up with MSDN[^]. Using that link you can ask what sites are in a collection, enumerate them, and get/set some properties.

Sorry, but this website isn't a code to order service. The purpose of these forums is to help with problems you encounter while trying on your own.

Give it a go yourself and if you encounter a problem, post your code and we will try to help you.

You might also search the abundance of articles here to get some inspiration or maybe even find exactly what you're looking for.

You are right. i should post my code here first...Sorry for my current work.

Thank you for you advice... i am going to correction it Big Grin | :-D

C#

how do I get the information from a site of a button?

What information from what button?
Your question is not clear

information is passed !! as login and password etc

As Chill60 says, this is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
We only get exactly what you tell us to work from - and you haven't told us what environment you want to work in (Website? WinForms? WPF? Console? Other?), where the "site" is, what "button" is involved, or even what kind of information you are trying to get from where! Laugh | :laugh:

Try and explain as if you were talking to your mother on the 'phone - that way you don't assume knowledge we don't have so much!

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

information that the Website Button is passing

What website?
Do you really think that you are supplying enough information for anyone to help you?

Stop typing as little as possible and think about the question you want answered: at the moment you have done the equivalent of breaking down in the middle of nowhere and calling the garage and saying "It Broke". When they ask "what's the problem, what's the car, where are you?" all you do is say "It's a Ford" and put the phone down. How long do you think it will be before the garage arrives with the right bits to fix your car?

We're the same: there are potentially thousands of possible combinations of ways you could mean - and we have no idea which one you are trying to get to. So help us to help you!
