Could someone please point me to a really good example/tutorial for creating a user control? Specifically I need to create an object that I can place on a form and get mouse click events from. Thanks!

A basic user control, as created by the wizard, will, by definition, get mouse events. You just need to handle them in your code, so you can interact with them

One of the columns in my datagridview is a combobox column. The datasource for the combobox is a datatable. When the user selects an item from the combobox he wants that item to be removed from the list so that when he navigates to a different line in the datagridview and picks an item from the combobox the previously selected item would appear in the list. How can this be done?

Remove the item from the datatable and it will remove itself from the combo box

I've tried that already. If you remove the item that is selected in the combobox, VS displays an error that keeps coming back when you close down the error dialog box. It seems VS cannot display the item in the combobox if it is removed from the list.

You are not going to be able to use databinding for your combobox. You should be able to create your own combobox column and when it is activated you can load the allowed list of values in the drop down.

or on selected item changed:
me.combobox1.items.remove(me.combobox1.selecteditem)

when adding data from a list box to a text box the data is add on after the other
eg. (123456789)
i would like to know if there is a way to make them appear one under another
eg.
1
2
3
4
5

Hi,
the magic value Environment.NewLine causes a string to span more than one line;
use it at your leisure, every time you want to start a new line in a file,
a textbox, etc. Like so: myTextBox.Text="1"+Environment.NewLine+(2).ToString();
BTW: some people use "\n" or '\n' ; on a Windows PC it would have a similar
effect; but other systems may not like it that much.

|
|
|
|
When your adding include chr(13) & chr(10) characters.
|

Better to use Environment.NewLine becuase it will return the correct value for the operating system in which you are running.

What do you expect us to do? Your question is not clear I have no idea what you really need help with. Are you using notepad for something? It sounds like you are trying to catch keyboard entry. What are you trying to do?

I am afraid Bill has beaten you to that
If you mean you want to create a Notepad lookalike, maybe based on a (Rich)TextBox,
and (its getting a big if) your cursor moves in strange ways when hitting
arrow keys on a (R)TB that is holding jagged text, then I suggest you consider
using the RichTextBox class, not the TextBox, and read up on it; I trust
the RichTextBox.GetLineFromCharIndex() and GetPositionFromCharIndex() methods
would interest you.

i read text file to view it in printpreview control
i use stream reader to read line by line and i use e.graphices.drawstring to draw line but i must give it font & brush to draw lines so i give them static lines like arial and blue color except of taken this line font and color
this is my code
---------------------
Private Shared filePath As String = Windows.Forms.Application.StartupPath & "\MyDoc.txt"
Private myFont As Font = New Font("Arial", 10)
Private myBrush As Brush = Brushes.Black
While currentLine < linesPerPage
textLine = streamToPrint.ReadLine()
If textLine Is Nothing Then
Exit While
End If
verticalPosition = topMargin + currentLine * myFont.GetHeight(e.Graphics)
e.Graphics.DrawString(textLine, myFont, myBrush, horizontalPosition, verticalPosition)
currentLine += 1
End While

i mean, how user can run my config.exe from windows control panel?
|

I'm not sure I'm getting this right
are you trying to add a prog to the control panel that will configure another prog of yours??
or what are you excatly trying to do??
|
|
|
|
|
I have a configuration program, it sets sql connection, some parameters etc. of another program. And I want to run it from control panel.
|
|
|
|
|
I don't know how to place it on the control panel but the some maps in the control panel are accesable
for instance:
C:\Documents and Settings\All Users\Menu Start\Programma's\Systeembeheer (english=systemconfig (I think))
maybe you can put you'r prog in there
|
|
|
|
|
AFAIK control panel items are stored in files with .CPL extension
I suggest you search for "CPL control panel" on CodeProject and Google.

Is there a way, I probably have not found it yet, to see the binary equivalent to the data I am putting in a method. I want to step through my program and hover of variable and see the binary code of the character. Is there a way to do that? Like or parse or somthing?
nextone = nextone << 8
While testing (debugging) I want to see the binary beginning and ending values of the binary data for Example nextone variable to see if shift happens correctly.
Thank you.
