Problem placing the TableLayoutPanel at the same location!

Hello everyone,

I am working on an Windows Application which I need to change the loaction of a TableLayoutPanel at the RunTime. I use the following code in order to do this.

this.tableLayoutPanel8.Location = new System.Drawing.Point(771, 3);

I was wondering if the specific loacation (771, 3) is refrence to the screen or the actuall Windows Application? Since the TableLayoutPanel is placed in the SplitContainer with ScrollBar to provide access to the entire Control Panel, I get the feelling that the above line of code locate the TableLayoutPanel on a different spot depending on the position of the ScrollBar.

I was wondering if it is possible to place the TableControlPanel at the same spot regardless of the ScrollBar position?

Thank you very much and have a great day.

Hello,

The Location, means allways the Location inside the Container (SplitContainer in your case)!

Process.Start with specific Culture Setting

Hi,

my application (C#) can run with a culture set from a config file (e.g. "en-GB") that is different from the systems CurrentCulture (e.g. "sv-SE"). Is it possible to start a another process via System.Diagnostics.Process.Start with modified culture settings so that the new process has same CurrentCulture as my application?

Example:
Systems CurrentCulture = "sv-SE"
myApp CurrentCulture = "en-GB" (set from config file)
wanted: newProc CurrentCulture = "en-GB"

Thanks
Rolf

Hello,

I never tried it, but looks good to me.

The Process class provides a Collection of "Threads" over which the CurrentCulture of all threads from the process could be set.

foreach(Thread actThread in ProcessYouWantToStart.Threads)
{
    actThread.CurrentCulture = yourCulture;
}

Please tell me if it works for you!

All the best,

Martin

Hello Martin,

this doesn't work. Reasons:

- Process.Threads is a collection of ProcessThread and shows the threads of a running process.
- ProcessThread has no property to set the CurrentCulture.
- CurrentCulture has to be set before starting the process because the new process configures its ressource management immediatly after starting.

Thanks,
Rolf

24 bit bitmap doubt ..

Software_Specialist2-Aug-07 2:37

Hi i am trying to check whether the bitmap file is 24 bit or not.
For this i have written a below code

<br />
FileStream File<br />
byte[] buffer = new byte[2];<br />
File.Seek(28,0);<br />
File.Read(buffer,0,2);<br />
Int16 nBit = BitConverter.ToInt16(buffer, 0);<br />

The above code works fine and give me the value of nBit as 24. But i don't understand the exact working of it.

Ok first it creates 2byte array, then i have a doubt over 2nd line i.e.
File.Read(28,0); Why current position is set to 28 here....??
It gives correct value when i set that to 28 and by next line the position jumps 2 place further i.e. 30 and by then i get correct value 24.
Can any one please explain me this behaviour...?

Thanks

See The .bmp file format[^]. Note that this lists the fields starting from byte position 1, while the .NET Framework starts counting at 0.

Stability. What an interesting concept. -- Chris Maunder

Hi,

28 is an offset in bitmap file which store information about number of bits per pixel. For additional information about bitmaps format you can see Bitmap Image article.

the above post probably covers the api you need for filestream and binarywrite.

so my post is just to point out it would be easier to use

FileInfo and FileInfo.CopyTo

if your just copying the file and dont want to edit it.

  FileInfo tes = new FileInfo(StrFilePath);<br />
<br />
        if (!tes.Exists)<br />
            return;<br />
<br />
        tes.CopyTo(StrDestPath);

or some such off the top of myhead

combobox problem

akkram2-Aug-07 2:02

Hi im using a combobox which is populated with a fairly large amount of items (no databind). The problem im having is that sometimes when I expand the combobox it wont stay open as it should so I can scroll down/up through the items, instead it closes as soon as you release the mouse button. Anyone have any idea to why this is happening?

/thanks

Hello,

One possibility is that you move the mouse outside the Controls area, while the mouse button is pressed.
If you than release the button, the items are still all visible!
This is per design!

You could make a workaround like this.

private void comboBox1_MouseLeave(object sender, System.EventArgs e)
{
	if(this.comboBox1.DroppedDown)
		this.comboBox1.DroppedDown = false;
}

Or inherit your own combobox, and override OnMouseLeave.

All the best,

Martin

Hmm sorry to say, but that is not the case. The combobox opens on mouse down and closes on mouse up even though the pointer never leves the combobox control area.

YEP, I never said something else! (I hope so)

What I meant is, that you sometimes leave the area (as a mistake), and than you have this effect!

All the best,

Martin

Insert 20,000 records with NHibernate

I am using NHibernate to insert into a database 20,000 records. I would like to know if a time of 15 sec is good or bad and if my method is the best. The code that inserts is this:

private void btnInsertHuge_Click(object sender, EventArgs e)
{
    ITransaction tx = null;
    ISession session = null;

    try
    {
        session = factory.OpenSession();
        tx = session.BeginTransaction();

        InsertHuge(session);

        tx.Commit();
    }
    catch (Exception ex)
    {
        tx.Rollback();
        throw ex;
    }
    finally
    {
        if (session != null)
            session.Close();
    }
}
...........................

private void InsertHuge(ISession session)
{
    for (int i = 0; i < 20000; i++)
    {
        Person person = new Person();
        person.LastName = i.ToString();
        person.FirstName = i.ToString();
        person.PhoneNb = i.ToString();

        Car car = new Car();
        car.LicenseNumber = i.ToString();
        car.Name = i.ToString();
        car.Owner = person;

        session.SaveOrUpdate(car);
    }
 }

NOTE: This is just a test. Smile | :)

As you adding a Car relation to Person, you are actually inserting 40 000 objects (i think Poke tongue | ;-P
