Assuming you&#39;re referring to WinForm Control events, from the MSDN documentation for [Control.Click][1]:

&gt; The Click event passes an EventArgs to its event handler, so it only indicates that a click has occurred. If you need more specific mouse information (button, number of clicks, wheel rotation, or location), use the MouseClick event. However, the MouseClick event will not be raised if the click is caused by action other than that of the mouse, such as pressing the ENTER key.

  [1]: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.click.aspx

A click can be caused by not only a mouse click, but also some events like a pressed key, etc. For more information, see *[Control.Click Event][1]*.

Before I retrieve data I always have to type:

    $STH-&gt;setFetchMode(PDO::FETCH_OBJ);

In the interest of making my code more readable it would be great if I could set a default mode somewhere....

Thanks!

**Edit**. I was originally hoping I could add PDO:FETCH_OBJ to the [setAttribute][1] code I run when I connect to the DB, but that doesn&#39;t seem to work...

I want to check type of value in postgres like this:

    SELECT id,
           CASE 
             WHEN val_is_integer THEN (SOME_QUERY)
             WHEN val_isnot_integer THEN (ANOTHER_QUERY)
             ELSE 0
           END
      FROM test;

How to do that?

notes:
the value is varchar type in table, and in that field there is value is numeric and varchar ...

example:

    ID | value
    1 | test
    2 | 10
    3 | 12
    4 | test123

How can I add and read the value from **web.config** file?

Read Variable from Web.Config

If I run a process with `ShellExecute` (or in .net with `System.Diagnostics.Process.Start()`) the filename process to start doesn&#39;t need to be a full path.

If I want to start notepad, I can use

    Process.Start(&quot;notepad.exe&quot;);

instead of

    Process.Start(@&quot;c:\windows\system32\notepad.exe&quot;);

because the direcotry `c:\windows\system32` is part of the PATH environment variable.



how can I check if a file exists on the PATH without executing the process and without parsing the PATH variable?

    System.IO.File.Exists(&quot;notepad.exe&quot;); // returns false
    (new System.IO.FileInfo(&quot;notepad.exe&quot;)).Exists; // returns false

but I need something like this:

    System.IO.File.ExistsOnPath(&quot;notepad.exe&quot;); // should return true

and

    System.IO.File.GetFullPath(&quot;notepad.exe&quot;); // (like unix which cmd) should return
                                               // c:\windows\system32\notepad.exe

I have a form **&quot;fm&quot;** that is a simple info window that opens every 10 mins (`fm.Show();`).

How I can make that every 10 mins it will check if the form **&quot;fm&quot;** is open and if it is open it closes it and open it again!

Now the form fm is always created with `form fm = new form();`  
so when I try to check if the form is open it will always be false and open a new window even if there is one form before!

I need to have a tool to give it a unique identity and then check if this form with unique identity is opened or not!

I do not want to just update the data on the form (fm), because I have a complicated info with buttons.

The form name is `&quot;UpdateWindow&quot;`

Thanks

Proper object disposal removed for brevity but I&#39;m shocked if this is the simplest way to encode an object as UTF-8 in memory. There has to be an easier way doesn&#39;t there?

    var serializer = new XmlSerializer(typeof(SomeSerializableObject));

    var memoryStream = new MemoryStream();
    var streamWriter = new StreamWriter(memoryStream, System.Text.Encoding.UTF8);

    serializer.Serialize(streamWriter, entry);

    memoryStream.Seek(0, SeekOrigin.Begin);
    var streamReader = new StreamReader(memoryStream, System.Text.Encoding.UTF8);
    var utf8EncodedXml = streamReader.ReadToEnd();

I have form which is opened using ShowDialog Method. In this form i have a Button called More.
If we click on More it should open another form and it should close the current form.

on More Button&#39;s Click event Handler i have written the following code

  

    MoreActions objUI = new MoreActions (); 
    objUI.ShowDialog();
    this.Close();

But what is happening is, it&#39;s not closing the first form. So, i modified this code to 

  

    MoreActions objUI = new MoreActions (); 
    objUI.Show();
    this.Close();

Here, The second form is getting displayed and within seconds both the forms getting closed.

Can anybody please help me to fix issue.  What i need to do is, If we click on More Button, it should open another form and close the first form.

Any kind of help will be really helpful to me.

How to open a new form from another form

I&#39;m using a DataGridView with object data binding to display information about logging entities in a system, retrieved via SOAP from a remote service.
One of the columns is called &quot;Last action&quot; and means the last time the entity logged a message. It is a `System.DateTime` value. When I read the SOAP response (example below), he timestamp obviously contains all the information, up to second fractions.

    &lt;LoggingEntity&gt;
    &lt;host&gt;marty86ce&lt;/host&gt;
    &lt;process&gt;10148&lt;/process&gt;
    &lt;logger&gt;http_core&lt;/logger&gt;
    &lt;appName&gt;httpd&lt;/appName&gt;
    &lt;ffda&gt;true&lt;/ffda&gt;
    &lt;lastAction&gt;2010-10-27T12:00:19.5117509Z&lt;/lastAction&gt;
    &lt;lastHeartbeat&gt;0001-01-01T00:00:00&lt;/lastHeartbeat&gt;
    &lt;channelId&gt;em_9BA2A2B4D0B6E66&lt;/channelId&gt;
    &lt;ffdaChannelId&gt;em_E7C8D1D4DE8EEB9&lt;/ffdaChannelId&gt;
    &lt;/LoggingEntity&gt;

When I display it on the table, I instead can read up to the minutes
![http://i.stack.imgur.com/dLYBz.png][1]
I use the following code to do the data binding when I press the refresh button

    public void RefreshEntities()
    {
        IEntityManagement management = EntityPlugin.GetProxy();
        LoggingEntity[] result = management.FindLoggingEntities(new TemplateQuery { ffdaSpecified = true, ffda = true }); //Remote invocation

        Invoke(new MethodInvoker(delegate { gridEntities.DataSource = result; })); //THIS does the data binding from the array

        Invoke(new MethodInvoker(delegate { btnRefresh.Enabled = true; }));
    }

I would like to know how to control column formatting of data bound values. I think that the format dd/MM/yyyy hh:mm comes from my system&#39;s settings. **How to override formatting settings programmatically?**

Thank you in advance

How to format DateTime columns in DataGridView?

Short question here:

In **.Net 4.0 Winforms**, how do I use the `PasswordChar` property of a `Textbox` to show a common **black dot** as a **character**? Is there perhaps some font I can use that has this as a character?

If I use &#39;`UseSystemPasswordChar = true`&#39; it shows an asterisk (*).
