How do i make the scrollbar stay at the bottom of the page. Iam developing an application in .net in where im displaying a datalist in a window and I am adding items to the datalist at runtime. Its size goes on increasing and i want the scroll for for this to remain at the bottom so that im able to see the last item entered.

Without knowing exactly how you're displaying things, the general technique for this is to write code that selects the last item in the control (thus moving the view to make it visible). If that is out of the question, you could record the current selection first, then move back to that one after making the last item visible.
Certain types of controls behave better in this respect. Check to see which controls could possibly display the data you want, maybe one of them has a method that handles this easily.

Hi
You can create a Panel and set its Dock property to DockStyle.Fill (to fill the form) and move your objects (e.g Datalist) to the panel (except the statusbar)
Unfortunately, you can't handle the Scroll event because Panel doesn't have this event.

Can someone advise me on how to convert hex conversion in C#? I am currently trying to get the string in a textbox, say "20" and convert it to its hex form 14, and then display it onto another textbox.

From help (I did something similar to this) :
Console.Write("{0:X}", 250);
I'm not sure if you can do that directly to a string or if you need to use a StringBuffer class like I did.
This is some code how I retreived color codes in individual colors (in bytes) and converted them to hex strings.
<br />
StringBuilder oBuffer = new StringBuilder();<br />
string strColorCode = "";<br />
byte byRed = 0;<br />
byte byGreen = 0;<br />
byte byBlue = 0;<br />
<br />
<br />
byRed = oColor.R;<br />
byGreen = oColor.G;<br />
byBlue = oColor.B;<br />
<br />
strColorCode = "{0:x2}{1:x2}{2:x2}";<br />
oBuffer.AppendFormat(strColorCode, byRed, byGreen, byBlue);<br />
<br />
return oBuffer.ToString();<br />
There are only 10 types of people in this world....those that understand binary, and those that do not.

I just found out how to do the conversion, thanks to your format string :
strColorCode = "{0:x2}{1:x2}{2:x2}";
This is what i did :
short sh = System.Convert.ToInt16(tbTextBox.Text, 10);<br />
tbTextBox2.Text = String.Format("{0:x2}", sh);

[using SWF;]
int i = 20;
txtBox1.Text = i.ToString();
txtBox2.Text = i.ToString("x");

Thanks... This seems like a more straight forward method

How do I emulate a union structure in C#?

Note the attributes StructLayout and FieldOffset.
[StructLayout(LayoutKind.Explicit)]
public struct SampleUnion
{
[FieldOffset(0)] public bool Flag1;
[FieldOffset(1)] public bool Flag2;
[FieldOffset(2)] public bool Flag3;
[FieldOffset(3)] public bool Flag4;
[FieldOffset(0)] public long Composite;
}

Thanks. So for the BE_CONFIG union in the LAME api I should just start every inner struct at FieldOffset(0)?

Shouldn't the Composite member be of type Int32 (int)? Longs in C# are aliases to Int64s.
[edit] I guess you could use a long if you'd like because this is a union (also only a sample  ).Just the first four bytes of the long will be used when dealing with the booleans.
Also remember that these unions in C# are not CLS compliant. [/edit]

Hmmm... what's a signature?

I suppose it would be a "best programming practice", however because in C# a long maps to System.Int64 I am o.k.

Yeah what exactly does cls compliant really mean? Is that the same as a Microsoft Certified Professional?

It means that the publicly exposed interface for the member/type/assembly follows the Common Language Specification (CLS).
Some things that aren't CLS Complaint: Unsigned integer types (C#), varying public items by changing just the case of the name (like public int Foo and public int foo).

I'm looking for class or even just tips on how to get this done. I want to convert targa image files to either .jpg or .gif (generally something that will display properly on website). I'm not overly advanced in using C# but if given good enough pointers I could probably pick it up, though finished class would be better, I learn best from examples too

Following a selection I am generating a report in pdf format saving it to the server and then displaying it to the user using the folling code that runs at the end of the btnClick event.
scriptstring= "mywindow = window.open('" + rPath + "','" + sWindow + "','height=350,width=532,toolbars=no,resizable=no')" + "<" + "/script>";
RegisterStartupScript("Startup", scriptstring);
The problem is that the report is displaying under the page rather than on top of it. How can I accomplish this?
Thanks

Does any one know if it is possible to add a form to a panel? Thanks

I don't think so...
You should use a UserControl...

I have an mdi application where the parent window is split in two horizontally. So I have a left side and a right side and the left side is part of the parent window. The left side contains navigation which determines which window will be displayed on the right hand side. But I want the max size of the children window to be no bigger than the area on the right hand side. Right now the children window overlaps the left hand side.

Yes, it is possible, but not really recommended unless you change the FormBorderStyle.
MyForm form = new MyForm();
form.TopLevel = false;
form.Location = new Point(5, 5);
this.Controls.Add(form);
form.Show(); The only two things you HAVE to do is set TopLevel to false, and call Show. Don't forget that if the user clicks the close button on the form then the form object get's Dispose'd -- yet another reason to change the forms FormBorderStyle or at least hook the form's Closing event.

I do need to change the FormBorderStyle. Can you give a little more detail on why it is not recommended? Is it only because of changing the FormBorderStyle or are there other reasons as well?

I don't recommend adding a form to a panel UNLESS you change the border style. Otherwise you wind up with a form that can be moved around (not so bad if that is the intended purpose) but it can also be closed which can be a problem.

I am writing a compiler using C# and the System.Reflection.Emit classes. The problem I am having is that I go through and create my classes for my language using TypeBuilder but I can't use those classes until I call CreateType. This wouldn't be a problem except that I potentially have to define instances of the class within the class (and therefore before I call CreateType). An example of this would be a linked list node that contains an instance of itself as the next node.
So the real question is if there is some way to get the System.Type of a TypeBuilder before calling CreateType. Or alternately, is there some way to add functions and variables to an already created type that I still have the TypeBuilder for but have called CreateType? I need this because many things need a System.Type and I need to allow users to use the classes they create while programming.
Thanks
