Set `ComboBox.DropDownStyle` to `ComboBoxStyle.DropDownList`.

After trying ShaneFulmer&#39;s answer, I noticed that the style of the drop down was changed. This was a problem for me and apparently there is no good way of changing it. (Background color doesn&#39;t actually change it.)

I ended up adding a keypress handler to prevent adding text.



    private void myCombo_KeyPress(object sender, KeyPressEventArgs e)
    {
        e.Handled = true;
    }

I want to convert the first character of a string to Uppercase and the rest of the characters to lowercase. How can I do it?  

Example:

    String inputval=&quot;ABCb&quot; OR &quot;a123BC_DET&quot; or &quot;aBcd&quot;
    String outputval=&quot;Abcb&quot; or &quot;A123bc_det&quot; or &quot;Abcd&quot;

What&#39;s a good directory structure for larger C++ projects using Makefile ?

This is how my directory structure looks at the moment:

    lib/ (class implementations *.cpp)
    include/ (class definitions *.h)
    tests/ (main.cpp for quick tests)

Now, I&#39;m not sure how my Makefile should look like... it doesn&#39;t seem to work when .cpp files and .h files aren&#39;t in the same directory. Could anyone point me to a common directory structure with an accompanying Makefile so that I don&#39;t reinvent the wheel ?

So that it just allows selecting items already inside, but not allow typing/editing the text inside it?

I am using the following code to fire the iexplore process. This is done in a simple console app.

    public static void StartIExplorer()
    {
        var info = new ProcessStartInfo(&quot;iexplore&quot;);
        info.UseShellExecute = false;
        info.RedirectStandardInput = true;
        info.RedirectStandardOutput = true;
        info.RedirectStandardError = true;
    
    	string password = &quot;password&quot;;
        SecureString securePassword = new SecureString();
    
        for (int i = 0; i &lt; password.Length; i++)
            securePassword.AppendChar(Convert.ToChar(password[i]));
    
        info.UserName = &quot;userName&quot;;
        info.Password = securePassword;
        info.Domain = &quot;domain&quot;;
    
        try
        {
            Process.Start(info);
        }
        catch (System.ComponentModel.Win32Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

The above code is throwing the error `The system cannot find the file specified`. The same code when run without specifying the user credentials works fine. I am not sure why it is throwing this error.

Can someone please explain?

Is there a short way to add List&lt;&gt; to List&lt;&gt; instead of looping in result and add new result one by one?

    var list2 = GetViolations(VehicleID2);

    list.Add(list2);

Returning a method value from **inside** a using statement that gets a DataContext seems to always work **fine**, like this:

    public static Transaction GetMostRecentTransaction(int singleId)
    {
        using (var db = new DataClasses1DataContext())
        {
            var transaction = (from t in db.Transactions
                                  orderby t.WhenCreated descending
                                  where t.Id == singleId
                                  select t).SingleOrDefault();
            return transaction;
        }
    }

But I always feel like I should be **closing something** before I break out of the using brackets, e.g. by defining transaction **before** the using statement, get it&#39;s value **inside** the brackets, and then returning **after** the brackets. 

**Would defining and returning the variable outside the using brackets be better practice or conserve resources in any way?**




Are there any side effects of returning from inside a using() statement?

I want to deploy the release version of my application done in C#.

When I build using the `Release` config, I still can see that `.pdb` files are produced, meaning that my application can be still debugged. This also means that some debug information is present somewhere in my code, slowing it down a little bit.

If this is true, how can I completely suppress any debug information produced in the binaries? Do you also know the reason of for having release `.pdb`? The `Release` configuration has the `Optimize code` checked, and only the `TRACE` constant is defined, not `DEBUG`.

Thank you for assisting.


C# release version has still .pdb file

There are other posts that say you can create a control in windows forms and then check the `InvokeRequired` property to see if the current thread is the main thread or not.

The problem is that you have no way of knowing if that control itself was created on the main thread.

I am using the following code to tell if a thread is the main thread (the thread that started the process):

    if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA ||
        Thread.CurrentThread.ManagedThreadId != 1 ||
        Thread.CurrentThread.IsBackground || Thread.CurrentThread.IsThreadPoolThread)
    {
        // not the main thread
    }

Does anyone know a better way? It seems like this way might be prone to errors or break in future versions of the runtime.

How would you implement paging in a LINQ query? 
Actually for the time being, I would be satisfied if the sql TOP function could be imitated. However, I am sure that the need for full paging support comes up sooner later anyway.

    var queryResult = from o in objects
                      where ...
                      select new
                          {
                             A = o.a,
                             B = o.b
                          }

I have a dialog that I show with `&lt;class&gt;.ShowDialog()`. It has an OK button and a Cancel button; the OK button also has an event handler.

I want to do some input validation in the event handler and, if it fails, notify the user with a message box and prevent the dialog from closing. I don&#39;t know how to do the last part (preventing the close).

For winforms applications I&#39;m wondering what setup code should go in:

* MainForm() 

as opposed to 

* MainForm_Load(object sender, EventArgs e) 

Are there any best practice guidelines here?
