Does anyone know how to set the position of the horizontal scrollbar for a datagrid?
Thanks

i guess thats the most challenging part when using scrollbars to a grid, what position you want to set?

I am not using a web control. I am using the default datagrid settings, so a scrollbar is automatic when larger than the panel it is controlled in. Any idea how to set the position?
Thanks!

Hello,
I am try to create some chort-cuts for my player. In order to set the short-cut to "P" i used the following code and it works fine.
if (e.KeyCode == Keys.P)
{ menuPbackPlay_Click(null, null); return; }
How can I change this to a combination key such as "Ctrl" and "P"? I tried the following and it didn't work. I don't get error bbut nothing really happens too!  )
if (e.KeyCode == (Keys.Z & Keys.ControlKey))
{ menuPbackPlay_Click(null, null); return; }

Hello again,
Shortly after posting, my google search lead me to the answer.
This is the answer for those with the similar problem.
if (e.KeyCode == Keys.P && e.Control == true)
{ menuPbackPlay_Click(null, null); return; }

I want to get the difference between two dates by days as integer
Thanks for help
Dad
|
|
|
|
|
int differenceInDays = latestDate.Subtract(newerDate).TotalDays;
|
|
|
|
|
I can not find "TotalDays".

This[^] method deals which what you want to do, the TotalDays property is a member of the TimeSpan structure.
|
|
|
|
|
DateTime date1, date2
System.TimeSpan datediff
System.TimeSpan datediff = date1.subtract(date2)
Response.Write(datediff.TotalDays);

Can anyone give me a link to sources on the web or hints on how to write a program the will add and option to program window that minimize it to system tray? I want to do something simular to http://www.actualtools.com/windowmenu/ but only I only want to add a button to all application windows that will allow me to minimize it to system tray. For instance, if I startup Outlook it will automatically have this "minimize to system tray" added button it. If I run any application it will automatically have this "minimize to system tray" button added to it.
Thanks,

I have been trying to create a setup project for an application. I am having trouble with one aspect however. I simply want the installer to execute another small program I wrote during installation. This other program applies some additional settings. I placed this executable under the custom actions tab in the "install" folder. I expect this to run once during installation, but I instead find that it runs every time I double-click on the newly installed applications shortcut. Why in the world would this custom action execute every time the new program is run? And where is the exe for this custom action being stored since its not in the installation directory?
Thanks.

Hello!
I have a problem with creating these arrays. The MAXNumberOfVectors and the MAXNumberOfVertices get the error to be used as a type name instead.
How do I do this, because this won't compile as it is, and I don't have a clue as to why this is... I am sure there must be a slightly different way to do this in C#. But that I couldn't find in my books how to do this.
Please some advice...
Thanks,
Ranger.
public class Storage
{
public int CenterX = 150;
public int CenterY = 150;
public int NumberOfVectors = 0;
public int NumberOfVertices = 0;
public const int MAXNumberOfVectors = 100; <-- compile time error
public const int MAXNumberOfVertices = 200; <-- compile time error
public Vector[] StoreVectors = new Vector[MAXNumberOfVectors];
public int[] StoreVerticesFrom = new int[MAXNumberOfVertices];
public int[] StoreVerticesTo = new int[MAXNumberOfVertices];
public Point2D[] StorePoints = new Point2D[MAXNumberOfVectors];

Well, I looked around in articles on this site, and found a reference to a method that creates an instance for an array, where you can determine yourself what the size and type of this array is. So I tried the following way to get to declare an arry of a certain size.
Still I get the following error message and that I don't know what this message means.
Can anyone help me clear this last hurdle..?
Thanks,
Ranger....
Static member 'Aljo3D_1.Storage.MAXNumberOfVectors' cannot be accessed with an instance reference; qualify it with a type name instead
private const int MAXNumberOfVectors = 100;
private const int MAXNumberOfVertices = 200;
public Vector[] StoreVectors;
public int[] StoreVerticesFrom;
public int[] StoreVerticesTo;
public Point2D[] StorePoints;
public Storage()
{
Array StoreVectors = Array.CreateInstance(typeof(Vector), MAXNumberOfVectors);
Array StoreVerticesFrom = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StoreVerticesTo = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StorePoints = Array.CreateInstance(typeof(Point2D), MAXNumberOfVectors);
}

This works... I removed the word 'const' from the MAXNumber variables and now it compiles without errors.
I knew it was something simple.
Ranger. 
public int MAXNumberOfVectors = 100;
public int MAXNumberOfVertices = 200;
public Vector[] StoreVectors;
public int[] StoreVerticesFrom;
public int[] StoreVerticesTo;
public Point2D[] StorePoints;
public Storage()
{
Array StoreVectors = Array.CreateInstance(typeof(Vector), MAXNumberOfVectors);
Array StoreVerticesFrom = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StoreVerticesTo = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StorePoints = Array.CreateInstance(typeof(Point2D), MAXNumberOfVectors);
}

Use a List instead, unless you really want to have a maximum possible number.

Hi,
your code compiles just fine for me. This is what I have:
public class Storage {
public int CenterX = 150;
public int CenterY = 150;
public int NumberOfVectors = 0;
public int NumberOfVertices = 0;
public const int MAXNumberOfVectors = 100;
public const int MAXNumberOfVertices = 200;
public int[] StoreVerticesFrom = new int[MAXNumberOfVertices];
public int[] StoreVerticesTo = new int[MAXNumberOfVertices];
}
So I dont know what went wrong for you. Also I suggest you mention the exact
compiler message (instead of "wont compile" or "does not work" or so).
And there is nothing wrong in using the const keyword to indicate something will
never allow to be modified, it is considered good practice.
BTW I concur with Christian's remark to use some (unlimited) collection instead;
you seldom need to impose a maximum (you might want to do that when memory becomes
tight and can be better spent, or when simulating a fixed size cache, or so).

Well, I got an error message which disappeared after some trial and error changes to my code.

I read about that in a book about C# I bought, but I am a novice, so I plan not to bite off more than I can chew, because I found that <list> matter kind of complicated.
As it is I am amazed about what you can do with Microsoft Visual C# 2005 Express Edition.
With programming practice, I am getting more understanding of how to use classes to keep things relatively easy to understand as you program gets to be able to do more and more.
I am having a ball with Express Edition.
Thanks for your comment.
