Here is a problem description and a work around; don't know if this is the same work around you're using though.

Yes, it is like my problem. From within an control I want to remove i catch the event for removal request. That event is handled in the form and the control is removed upon this request.
I thought there could be problem with code sequence. Because after I handle the event in which I remove the control from ControlCollection, the flow of control returns to the control which was intended for removal (because it is demanding to be removed).
I will try you workaround and see.
Thank you very much.

How do I know which row in the rich text box has the focus now?
Say I am overriding WndProc and checking for WM_KEYDOWN I'd like to figure out which row in the rich text box the cursor is curently located.
I dont mean the screen row [if it has scrolled down quite a bit, the 3rd visible row on screen might actually be the 44th row] I want the actual row here because I want to get that line of text using the Lines property but for that I need to know the index of the row

Try counting the newlines (ie "\r\n")?
I think that should work...
Later,
Nathan

Hmmm... what's a signature?

Use the selectionstart property.
----------------
Quote from MSDN:
Gets or sets the starting point of text selected in the text box.
[C#]
public int SelectionStart {get; set;}
.
.
.
Remarks
If no text is selected in the control, this property indicates the insertion point for new text. If you set this property to a location beyond the length of the text in the control, the selection start position will be placed after the last character. When text is selected in the text box control, changing this property may decrease the value of the SelectionLength property. If the remaining text in the control after the position indicated by the SelectionStart property is less than the value of the SelectionLength property, the value of the SelectionLength property is automatically decreased. The value of the SelectionStart property never causes an increase in the SelectionLength property.
Note You can programmatically move the caret within the text box by setting the SelectionStart to the position within the text box where you want the caret to move to and set the SelectionLength property to a value of zero (0). The text box must have focus in order for the caret to be moved.
--------
The SelectionStart property should return the current position in the RichEditBox.
Hope this helps,
Nathan

I have a class derived from the System.Windows.Forms.TextBox.
I have overridden TextBoxBase.OnModifiedChanged but it never gets called even when I change the text in the text control
Has anyone else experienced the same problem?

Hi,
I was not able to find the option for PostBuild Action in the C# Project Properties.
(Where I can Specify some Dos commands to run after the project is Compiled)
Is there any alternative feature avaliable?
Thanks,
FiroZ

You can add an empty Visual C++ project and then do post builds from that project. Just make sure that the empty C++ project is built last in the solution.

MSDN has a BuildRules visual studio addin. It lets you add pre and post build commands to solutions and projects.
can't find the link right now... but i know it's on there somewhere

Some example code would be nice  Cant seem to work it into a form, seems a bit messed up 
And why does people write controls without default constructors?

Card[] crds = new Card[3];
crds[0] = Card.New("My Text", 0);
crds[0].Font = new Font("Times New Roman", 10, FontStyle.Bold);
crds[1] = Card.New("My Text", 1, CardShape.Circle);
crds[1].Shadow = false;
crds[2] = Card.New("Solid Colours", 1);
crds[2].CardUp = Color.SkyBlue;
crds[2].CardOver = Color.SteelBlue;
crds[2].CardDown = Color.Navy;
CardCtrl crd = new CardCtrl(crds);

Because they don't have VS.NET or they use MC++ to test it so they don't realize how important the default constructor is to the forms designer

You do use it, but you defer the setting of the various properties until a little bit later.
The "proper" way to create the control is to expose a Cards property which is a Collection of Card objects. The collection can then be modified at runtime and the control will update itself automatically.
An example of this set up is the ListView control; it exposes an Items collection which contains ListViewItems that represent the items in the control. This collection can be modified at runtime, or code can be output by the forms designer to add the items during the form's InitializeComponent() method.
At first this does not makes sense, but then there are added benefits to coding this way: The control is more flexible in that Cards can be added and removed at runtime; and it opens itself to be easier to use because it follows the standard set by the base controls.

I see what your saying, but the Cards array in the CardCtrl class needs to be sized correctly. So to add/remove cards at runtime, ive added an Add() and Remove() method.

Is there any way to figure out that specified assembly is loaded or not. What I am trying to do is I want to check if the assembly is already loaded or not. If not then load it if yes then use it from memory. I don't want to load the assembly all the time so just a check.
Thanks

How reliable and sturdy are the above classes?
Are they good enough to write a small server with upto 50 connections that will be passing a 40 character string to client machines over a LAN?
Any useful reading material for these and the base Socket classes? (beyond MSDN)

How can I write a user defined struct (like the following struct) in binary form to a file?
<br />
[StructLayout(LayoutKind.Sequential)] <br />
public struct BITMAPFILEHEADER <br />
{<br />
public ushort bfType; <br />
public uint bfSize; <br />
public ushort bfReserved1; <br />
public ushort bfReserved2; <br />
public uint bfOffBits; <br />
}<br />
And how can I write the data of a memory block (the only thing I have is the the "IntPtr") in binary form to a file?
IntPtr p --> file
Thanks, Daniel.
