Hi there fellow programmers!
I have a datagridview with say 20 rows, and I know that only ONE of them has a certain value in one of its cells. What I want to do is displaying this one row in top of the others, so it shows itself first.
There is no way i can set it first via sorting, and the FirstDisplayedScrollingRowIndex property doesnt seem to work unless Im doing something wrong - I'm setting in there the index of the row.
Any ideas? Thanks in advance

Hi Stefan Troschütz
Thank you i found the error
object [,,] myArray;
myArray = new object [,,] { { {"@EngCode"},{SqlDbType.Int},{TxtCode.Text} } };
---------------------------------
I Have a stroed procedure that take 13 parameter
CREATE PROCEDURE dbo.CreateUser
(
@EngCode int,
@EngFName nvarchar(20),
@EngMName nvarchar(20),
@EngGName nvarchar(20),
@EngLName nvarchar(20),
@EngNotes nvarchar(500) ,
@EngineeerTypeID int,
@UserName nvarchar(10),
@EngMail nvarchar(50),
@EngCellNo int,
@EngHNo int,
@UserPassword nvarchar(12),
@UserNotes nvarchar(500)
)
I call this proc from my C# sO
SqlParameter POne = new SqlParameter();
POne.ParameterName = "@ParaName";
POne.Value = MyText.Text;
POne.SqlDbType = SqlDbType.NVarChar;
MyCommand.Parameters.Add ( Pone );
i will repeat this operation 13 time But
if i had a Multidimensional array
myArray = new object [,,] { { {"@EngCode"},{SqlDbType.Int},{TxtCode.Text} } };
and have a foreach to loop; it would be then a better idea

You can write those five lines of code in a single line:
MyCommand.Parameters.Add(new SqlParameter("@ParaName", SqlDbType.NVarChar)).Value = MyText.Text;
Notice that the Add method returns a reference to the parameter, so that you can set the value property.
---
b { font-weight: normal; }

Hi
Thank you very much
But we should put it that way
MyCommand.Parameters.Add(new SqlParameter("@ParaName", SqlDbType.NVarChar).Value = MyText.Text );
Thank You again

No, that doesn't work. The value of the operation or assigning the string to the Value property, is the string. The result is that you will be throwing the SqlParameter object away and adding the string to the parameter collection instead.
Use the method that I showed, or this even shorter one:
MyCommand.Parameters.Add("@ParaName", SqlDbType.NVarChar).Value = MyText.Text;
---
b { font-weight: normal; }

If i do that:
Image img_1 = new Bitmap(200, 200);
Image img_2;
img_2 = img_1;
now there are two different objects in the memory so if i do:
img_2 = null;
then
img_1 = 200x200 bitmap
or that is the same object so:
img_2 = null
then
img_1 = null too?

img_1 and img_2 are both refferenes to the object, and not the object itself.
If you do this:
Image img_1 = new Bitmap(200, 200);
Image img_2;
img_2 = img_1;
Then apply some manipulation to img_1, these changes will also reflect in img_2.
If you do this:
img_2 = null
Then it now points to nothing, but img_1 is still the value it once was (200x200 bmp).
And this:
img_2 = img_1
img_2 = new Bitmap(50,50)
img_1 will be the origional 200x200 bitmap, while img_2 will be the new 50x50 bitmap.
hope that helps

I've been experimenting with remoting, and have got it fairly well figured out.
I'd like to play with app domains now, but have a few questions -
1) Firstly, when creating a program we have a "MAIN" method that takes a number of string arguments. Am i right in assuming that these are the "/w" "/r" "/filename" etc tags that we can specify as command line parameters after the .exe name in a given shortcut?
2) When an app domain is created, it will run and behave exactly as one would expect an application to behave. It will be started on a new system thread, and run until a set of conditions cause it to exit. I.e If we create a new AppDomain that is a windows forms App, it will look and behave like a windows forms app.
3) If the above are both right, it should be possible to write an app that will, on creation, take a number of arguments, and connect to a remote object (In this case the Application that created the new AppDomain).
What i would need to do is forward the remoting host destails in the apps main method but i don't know how to set them when creating an app domain.
Can anyone help me with this?
Cheers

A better solution would be to figure out whats causing the dialog to pop up in the first place and fixing that.

How can I close /kill an error message dialog appearing on the desktop automatically e.g. if a service crashes I want to close its error message.

First, your putting alot of effort into putting a band-aid on the real problem.
What's causing the service to crash?? Fix the problem, instead of wasting the time building an automated way of ignoring it.

Have you tried taking this up with the manufacturer of the service?
Maybe they have the solution...

The information you want doesn't exist in Active Directory and isn't tracked by anything.
What you want can't be done!!

What is the better way without quality less?

What is it that you want to do with the image?
---
b { font-weight: normal; }
|
|
|
|
|
I need to load Jpeg, gif or png files and save it to BMP 
|
|
|
|
|
Use Bitmap.FromFile to load the image, then use the Save method with ImageFormat.Bmp to save the image.
---
b { font-weight: normal; }
|
|
|
|
|
it is the better way? That is it is the less quality loser?
