Hi,
You can try using MD5. There is an encoder built in VS2005. However you must know that MD5 cannot be decoded so if you want to test the input password with a stored one you should convert the input password to MD5 and then compare it with the stored password. Search MSDN for MD5.
Hope it helps.

Can not start C# application without VS2005

Hello

I have a C# application that uses several Libraries (Crystal ...). The application always runs well.

Since a few days I focus the problem, that I can start my application only with the debugger (the Debug and the Release version).
If I start the *.exe directly, the application crashes ... Most times an 'Out Of Memory' exception occurs.
I added some debugging output and I see, that I enter the Main() but then it crashes ...

The application also crashes, if I take an old (former running) *.exe file.

Do you have any hint how I could handle it?

Thanks and best regards,
Martin

Hello!

I have an application that uses a tabcontrol with a couple of tabpages. However, I wonder if anyone knows if there is a way to make one of the tabs appear without clicking it?

Best regards,

Hampus

Set either TabControl.SelectedIndex or TabControl.SelectedTab property.

Yes. Use a timer to toggle between tabs, and on elapsed duration, send a click event to the tabcontrol with the required paramaters, simulating as if the user clicked. This will make teh tab control change the active tab, based on which tab index was passed in the event handler call

I have MyControl (Grid), and i override IsInputKey method in it.

protected override bool IsInputKey(Keys keyData)<br />
        {<br />
            bool bIsInputKey = true;<br />
<br />
            switch (keyData)<br />
            {<br />
                case Keys.Left:<br />
                    break;<br />
                case Keys.Right:<br />
                    break;<br />
                case Keys.Down:<br />
                    break;<br />
                case Keys.Up:<br />
                    break;<br />
                default:<br />
                    bIsInputKey = base.IsInputKey(keyData);<br />
                    break;<br />
            }<br />
<br />
            return bIsInputKey;<br />
        }

It work ok, but if i place MyControl on other control(TabControl for example), that don't respond to keys.
What i must do?

Thank's to all answers asap!

WPF BitmapImage and transparency

Does anyone know how you select a pixel from a BitmapImage instance, say the one at 0.0, and set that as the transparent color for a bitmap.

Have a look at the Bitblt in Win32 APIs.
thats one way fo doing this, though through Interop in .NET

Thanks for that.

With Windows Forms etc it was easy just

bitmap.MakeTransparent(bitmap.GetPixel(0, 0));

and I'm sure Bitblt would do it but I always try and avoid unmanaged code as it seems like such a backward step especially with WPF and XAML on the horizon.

Anytime Steve Smile | :)

Yes Bitmap class offers the transparency thing, but under the hoods its using the same API so i chose to put forward the native thing Big Grin | :-D

.

There are tons of benefits of blitting but then not all is offered through the GDI+ classes and the likes. MS is making life easier for us by putting better and more abstractions over the native ways....and that is really productive. However, knowing how my car runs can reduce my dependency on the mechanic Smile | :)

Do we need to call dbCommand.Dispose() ?

Hello !

I have a question about DB specifications :
Do we have to call IDbCommand.Dispose ?
What does IDbCommand.Dispose mean?
We have problem doing this :

<br />
IDbConnction pipe = new OleDbConnection(connString);<br />
IDbCommand command = pipe.CreateCommand();<br />
command.QueryString = "select ...";<br />
IDataReader reader = command.ExecuteReader();<br />
command.Dispose();<br />
reader.Close();<br />
pipe.Close();<br />

The problem get solved if we don't do IDbCommand.Dispose

Your comments would be very helpful. Thanks.

You cannot Dispose Command Object after ExecuteReader Method, the datareader object maintains the connection to the database as it will not pull all data at once, and it will pull data record by record. So dispose the command object after getting all the data.

Whenever a class exposes a Dispose method you should definitely call it as it frees resources immediatly. You can take advantage of the using statement that automatically calls Dispose on an object when execution leaves its scope. Simple example taken from MSDN.

using (Font font1 = new Font("Arial", 10.0f))
{
  //use font1 object
}

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
