You just draw a rectangle over the top of the image with the background colour! There's no magic "Eraser" tool in GDI like there is in, say, photoshop.

I suggest you stick to fixing one problem at a time, you are asking so many random questions, I doubt you are even attempting to find the answers yourself...

And just to be nice. There is an article somewhere on CP that shows you how to do this (was long ago, I cant recall name of it).

Advanced options > Refresh the dataset

I am trying to use objectdatasource control binded to a dataset in VS 2005.

I have clicked the Refresh dataset option and in the designer.cs generated code it generates below statement.

how do I retreive the autoincrement coloumn of _ENTITYID from the objectdatasource ?

Also when I run this SQL statement it gives me the last entered row to the table which is cool but

, I could not find it the @_ENTITYID in select parameters and insert parameters while debugging the objectdatasource control.

What should I do ?

Scrolling Progressbar

I have an application that does some work in the background so I need to show the user some kinda 'processing animation'. How do I make a progressbar that has 5 bars that scrolling left and right throughtout the entire width of the progressbar? This way I can show the user that my app is still working. Any other animation sequences you might know of.

how to place custom controls on top of the other controls

Ok I`ll try to explain my problem Smile | :)

. ComboBox, places his choice list on top of the other controls, including other panels and so on. The question is - how can I make other custom control maded by myself wich is added to some panel [mPanel.Controls.Add(MyControl);] - to show up on top of the other controls and other panels (like ComboBox choice list), but without separate it from [mPanel.Controls]. Can control actually act like ComboBox list on top of other controls?

I believe a ComboBox is rendered by the IE browser as a "window" control (as in a Windows Forms' control). Thus, the ComboBox will always appear over everything else. I don't know of any attractive solutions, however.

Actually I am talking about C# windows form. I have a grid in one panel, other grid in other panel. One of the columns contains comboboxes, ComboBox list, of course appears over the second grid, I want my custom control wich contains some textboxes and other crap show up in similar way. Way I am using - is separate form without close and minimize buttons, but it is not Control added to grid cell, it is separate windows form and it is not good solution, because it shows up in a taskbar and acts like form, but I want to attach it to the grid cell as a normal control Frown | :(

hi Oskars! Smile | :)

you can put you custom control on a floating window. this window will be on top of all window, just like the list of the combobox.

try to look at this[^] to have an idea how to make a floating window.

hope that helps! Smile | :)

C# Equivalent of "chunk_split"

Hello,
I am trying to convert this following PHP code to C# for Windows Application, (Not ASP.NET). My intention is to post file attachment to remote server by doing this. I know how to convert base64 in C#, but I dont know which Method of C# do this chunk_split. Can anyone please help !

string chunk_split ( string body [, int chunklen [, string end]] )
This functoin can be used to split a string into smaller chunks which is useful for e.g. converting base64_encode() output to match RFC 2045 semantics. It inserts end (defaults to "\r\n") every chunklen characters (defaults to 76). It returns the new string leaving the original string untouched.

What is the problem? From the description its pretty clear what it does, so just implement the same in C#. One way is to use a StringBuilder and inject '\r\n' at every 76 char interval.
