Re: Assigning Tuple.Create to a Func ? ... an interesting code fragment

Hi Bill,

there's not a lot of magic going on there. c is basically declared as an alias for Tuple.Create(int, string). You could remove the declaration of c and replace c(.., ..) by Tuple.Create(.., ..) or new Tuple(.., ..). Whether or not this is more readable or in just any way better is up to personal taste I guess.

cheers, Sascha

When you have a problem with code you got from an article, you should ask in the forum at the end of the article. It's very unlikely that the author of the piece will just happen on by and open your question.

I'd also recommend to include any exceptions or errors that you get. When you say that it can't connect, there's a dosen reasons, and the most likely is a firewall.

Try pinging the remote address. If it doesn't answer, then the sample-code won't work either.

Hi,

I have a simple POS application. I have included the Microsoft.PointOfService and Microsoft.PointOfService.ControlBase to my project and save it in my deployment project too.

Do I need to do anything else? or just deploying those two files is enough?

Thanks,

Creating a SELECT Query Based on Textbox Data

John L. DeVito19-Jul-15 4:59

19-Jul-15 4:59

I'm building a simple windows form app which stores all of my DVD's (pet project, just for learning; I'm sure there are plenty already out there). I'm able to add items into the database (azure SQL Server) perfectly, even leaving some or most textboxes blank (the title column is setup as NOT NULL in my table) but I can't get it to retrieve any data.

Here is my OnClick method:

private void searchButton_Click(object sender, EventArgs e)
{
	string qString = @"SELECT Title, Director, Genre, ReleaseYear, Length, NumberofDisks, Description FROM Base WHERE Title = '" + titleTextbox.Text + "' AND Director = '" + directorTextbox.Text + "' AND Genre = '" + genreCombobox.GetItemText(genreCombobox.SelectedItem) + "' AND ReleaseYear = '" + yearCombobox.GetItemText(yearCombobox.SelectedItem) + "' AND Length = '" + lengthTextbox.Text + "' AND NumberOfDisks = '" + numberOfDisksTextbox.Text + "' AND Description = '" + descriptionTextbox.Text + "';";
	
    string cString = @"Server=MyAzureServer,MyPortNumber;Database=MyDatabase;User ID=me@MyAzureServer;Password=MyPassword;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;";

	DataTable dTable = new DataTable();

	SqlConnection sConnection = new SqlConnection(cString);

	sConnection.Open();

	using(SqlCommand sCommand = new SqlCommand(qString, sConnection))
        {
        	try
		{
			SqlDataReader sReader = sCommand.ExecuteReader();
			dTable.Load(sReader);
		}
		catch(SqlException sEx)
		{
			MessageBox.Show(sEx.Message);
		}

		resultsDataGridView.DataSource = dTable;
	}

		sConnection.Close();
}

and here is my table:

SQL

CREATE TABLE [dbo].[Base]
(
	[MediaID] [int] IDENTITY(1,1) PRIMARY KEY,
	[Title] [nvarchar](50) NOT NULL,
	[Director] [nvarchar](50) NULL,
	[Genre] [nvarchar](50) NULL,
	[ReleaseYear] [date] NULL,
	[Length] [time] NULL,
	[NumberOfDisks] [int] NULL,
	[Description] [nvarchar](200) NULL
)

I absolutely realize this is open to SQL injection. My plan is to just 'get it working' and then I will go back over it and and change to parameterized queries (I have to read up on how to use them). The program compiles and runs fine. When I click the search button with all or any of the textboxes filled, it returns no results in the datagridview. The white grid shows up but it is empty. I can query the database directly and get the results I'm looking for, but not programatically. Do I need to build the query using logic? Since almost all of my columns accept null (except Title) I'm assuming leaving a field blank wouldn't be a problem, but even if I enter data into all of the available textboxes(exact matches including case just to be certain) I get no results. Am I missing something small and stupid?

Can anyone give me any help or hints? Please no laughing at my code or making fun of me Laugh | :laugh:

Thanks,
John

Please learn to use parameterized statements and NEVER use concatenation to provide values, especially values from the user.

You said that you know that the code is vulnerable to SQL injections but that is not the only reason why to use parameters. Another thing is that they help you with conversions. Consider for example dates and the date format or numbers. Using a correct format is difficult when the data is in text format.

Few other reasons why the query might not return any data

There are a lot of conditions. Since they are defined in the WHERE clause you cannot leave any of them empty and expect that the condition would be ignored. If a text box is empty the comparison will still take place
The operator for all conditions is AND so all the the conditions you have specified must be satisfied by a single row
You use equality in all comparisons. For example description is compared to the value from the text box using equality. This means that the text must match exactly and completely. This prbably isn't what you're after. Perhaps LIKE comparison?

Yeah, it'll help you to "get it working" if you just went to parameterized queries to begin with to help you avoid problems such as these and also makes it much easier to debug when you do run into problems.

Your WHERE clause is screwing you over somehow. Rewrite to help you debug the problem and make sure the parameters you're passing in are expected and correct.

If you leave one of your boxes open, let's say length, then your sql includes

WHERE length = ''

so you'll only get records where the length is empty. If you want to ignore a field if it is empty then your SQL needs to look like

WHERE
(@field1 IS NULL OR field1 = @field1)
AND (@field2 IS NULL OR field2 = @field2)

@field1 and @field2 are your input params, and field1 and field2 are the matching columns in your database. In order for this to work it'll be easier if you switch to params first. So if you want to ignore an element from the query then set it's param to dbnull.value if the associated textbox is empty.

That's a very bad plan. There's a good chance that you'll miss something, or forget to do it, or run out of time, or lose interest and move on to the next project... Smile | :)

Plus, as others have pointed out, using string concatenation to build your query will introduce new problems that you'll have to fix, which wouldn't be the case if you used properly parameterized queries.

Parameterized queries aren't particularly hard, particularly as you're using ADO.NET and SQL Server:

private void searchButton_Click(object sender, EventArgs e)
{
    // TODO: This should probably be in the configuration file:
    const string ConnectionString = @"Server=MyAzureServer,MyPortNumber;Database=MyDatabase;User ID=me@MyAzureServer;Password=MyPassword;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;";
    
    const string Query = @"SELECT 
    Title, 
    Director, 
    Genre, 
    ReleaseYear, 
    Length, 
    NumberofDisks, 
    Description 
FROM 
    Base 
WHERE 
    (NullIf(@Title, '') Is Null Or Title = @Title) 
AND 
    (NullIf(@Director, '') Is Null Or Director = @Director) 
AND 
    (NullIf(@Genre, '') Is Null Or Genre = @Genre) 
AND 
    (NullIf(@ReleaseYear, '') Is Null Or ReleaseYear = @ReleaseYear) 
AND 
    (NullIf(@Length, '') Is Null Or Length = @Length) 
AND 
    (NullIf(@NumberOfDisks, '') Is Null Or NumberOfDisks = @NumberOfDisks) 
AND
    (NullIf(@Description, '') Is Null Or Description = @Description)
;";

    DataTable dTable = new DataTable();

    using (SqlConnection connection = new SqlConnection(ConnectionString))
    using (SqlCommand command = new SqlCommand(Query, connection))
    {
        command.Parameters.AddWithValue("@Title", titleTextbox.Text);
        command.Parameters.AddWithValue("@Director", directorTextbox.Text);

        command.Parameters.AddWithValue("@Description", descriptionTextbox.Text);

        connection.Open();
        using (SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection))

an unexpected absence of fail ... using anonymous actions in a WinForm EventHandler

BillWoodruff19-Jul-15 4:05

BillWoodruff

19-Jul-15 4:05

I'm am puzzled by this:

1. I have a Dictionary whose Keys are Enumeration-Values, and whose Values are of Type Action<Control1, Control2>

2. At run-time I am calling a method that adds a LocationChanged EventHandler which is constructed as a lambda on-the-fly ... to Control1. This LocationChanged EventHandler will execute the Action described in #1 which will change the other Control, Control2.

When Control2 refers to a Form, and, at run-time, that Form has been closed using its Close Button: my impression, up to now, has been that references to that Form would be garbage collected, so if Control1 (another Form) was moved, and the LocationChanged event was triggered which attempted to modify Control1 (closed Form), I would expect a null reference error.

But, there is no run-time error thrown; I infer from that there must be valid references to the closed Form "still around."

I think I better illustrate this with a dumbed-down bare-bones code example: a WinForms project with a MainForm 'Form1, and second Form, 'Form2:

enum SomeEnum
{
    whatever1,
    whatever2
}

private Dictionary<SomeEnum, Action<Control, Control>> EnumToAction;

private void Form1_Load(object sender, EventArgs e)
{
    EnumToAction = new Dictionary<SomeEnum, Action<Control, Control>>
    {
        {
            SomeEnum.whatever1, (control, control1) =>
            {
                control1.Top = control.Top;
            }
        },
        {
            SomeEnum.whatever2, (control, control1) =>
            {
                control1.Left = control.Right;
            }
        }
    };

    Form2 f2 = new Form2();
    f2.Show();

    SetAction(this, f2, SomeEnum.whatever1);
}

private void SetAction(Control bControl, Control dControl, SomeEnum someenum)
{
    bControl.LocationChanged += (sender, args) =>
    {
        EnumToAction[someenum](bControl, dControl);
    };

    // execute once to set initial alignment
    EnumToAction[someenum](bControl, dControl);
}

Running the above code, then closing 'Form2 by clicking its Form Close Button, and then moving 'Form1 does not then throw an error which makes me believe that the reference to 'Form2 in that created-lambda EventHandler must still be valid.

I guess I could keep a Dictionary of Control, EventHandler around to deal with this ... to explicitly remove EventHandlers ... but, then, you've got different types of EventHandlers (differences in parameters) to deal with.

Ideas ?

thanks, Bill

Everyone knows that anonymous delegates cannot be removed so obviously there are places where they should not be used!

But what if?
What if the add and remove mechanisms are set up at the same time? Sure the delegate code is anonymous but, as you say in your message, a reference can be kept.

I have lambdaphobia so here is the great idea in old school code.

public class Form1 : Form {

  protected override void OnLoad(EventArgs e) {
    base.OnLoad(e);
    this.Text = "One";

    Form f = new Form();
    f.Text = "Two";
    f.Show();
    ISeeAWitch(this, f);
  }

  private void ISeeAWitch(Form bControl, Form dControl) {
    // I don't know who you are but I can point a finger at you
    EventHandler locationChanged = new EventHandler(delegate(Object sender, EventArgs e) {
      dControl.Left = bControl.Right;
      dControl.Top = bControl.Top;
    });

    bControl.LocationChanged += locationChanged;
    
    // I don't know who you are either but I can see that you are pointing at that other guy too
    dControl.FormClosed += new FormClosedEventHandler(delegate(Object sender, FormClosedEventArgs e) {
      if (bControl != null) {
        bControl.LocationChanged -= locationChanged;
        MessageBox.Show("I'm off");
      }
    });
    
    locationChanged(null, null);
  }
}

Thanks Alan, for this delightful code sample, and your comments.

I entertained the idea that the act of closing a Form at run-time might be somehow qualitatively different ... vis-a-vis garbage-collection ... than the act of disposing other objects. I'd say that was a poor choice of entertainment Smile | :)

I really like using Dictionaries whose keys are Enums and Values are executable code.

What you are seeing is by design as the garbage collector makes the following guarantees:

1. Every object will be destroyed, and its destructor will be run. When a program ends, all remaining objects will be destroyed.
2. Every object will be destroyed exactly once.
3. Every object will be destroyed only when it becomes unreachable, i.e. when there are no references to the object in the process running your application.

The garbage collector works on its own thread and can execute only at certain times, while it runs other threads in you application are temporarily halted in case it needs to move obects around and update references.

Generally the following steps are taken by the garbage collector:

1. builds a map of the reachable objects
2. checks if any unreachable objects have a destructor that needs to be run (i.e finalization, if any are found they are moved to a special queue)
3. Deallocation of remaining unreachable objects, and moves reachable objects down the heap, updates any references to the reachable objects
4. allows other threads to resume
5. Runs the finalized methods from number 2

I suspect the key is to look at what the compiler's doing behind the scenes.

Your anonymous LocationChanged handler closes over three parameters and an instance field, so the compiler will generate something like this:

private sealed class SetActionClosure
{
    public Form1 @this;
    public Control bControl;
    public Control dControl;
    public SomeEnum someenum;
    
    public void AnonymousLocationChangedHandler(object sender, EventArgs e)
    {
        @this.EnumToAction[someenum](bControl, dControl);
    }
}

private void SetActive(Control bControl /* == this */, Control dControl /* == f2 */, SomeEnum someenum)
{
    SetActionClosure closure = new SetActionClosure();
    closure.@this = this;
    closure.bControl = bControl; // == this
    closure.dControl = dControl; // == f2
    closure.someenum = someenum;
    
    bControl /* == this */ .LocationChanged += closure.AnonymousLocationChangedHandler;
    ...
}

The instance of the closure class will remain alive as long as the event handler still has a reference to it - ie: until you unsubscribe the handler, or close the Form1 instance.

That closure class instance has a reference to the Form2 instance "f2". That Form2 instance will remain in alive for as long as the closure class instance remains alive.

There really isn't anything we can do to help here: there are just too many variables.

So start by looking for differences between the PC where it works - your development PC - and teh PC where it doesn't. Look at the OS, the size (32 bit / 64 bit), the .NET versions installed, the datafiles your app uses, databases, the disk space, anything which is different. If you can't find anything there that looks significant, then start by adding logging info to your app and work out how far it gets before it crashes.
Then, narrow the area down with more logging, and start using try...catch blocks to try and find out what the exception (if any) is.

There isn't anything we can do from this end: you need to gather information and start thinking about your code - which we can't do because we have no access to it!

There is a good change you didn't deploy one or more .DLL's those referenced .DLL's depends on. With the information you provided there isn't enough information to tell which .DLL(s) are missing dependencies, if any.

I suggest you go down the list of the assemblies you references and get the documentation on each library to see if you have to do something special on the client machine to deploy that library.

I haven't tried it, but you might want to start looking at GMaps.Net[^]
