How about adding picture boxes to a panel? You can make the panel scrollable to accomodate for a large number of images.

Despite everything, the person most likely to be fooling you next is yourself.

Hi,

I am looking for information about this topic's description.
magic wand tool 'photoshop'
fuzzy select tool 'the gimp'

I'm not sure what this implementation is called, and have been searching the net for quiet some time.

I'm developing in C#

I need to click part of an image, and based on that pixels color find the adjacent pixels with a tolerance based on the original color.

I hope this explanation is satisfactory, any information would be greatly appreciated Smile | :)

Thanks.

You want to look for edge detection algorithms. http://www.ii.metu.edu.tr/~ion528/demo/lectures/6/1/index.html[^]

Need custom software developed? I do C# development and consulting all over the United States.

If you don't ask questions the answers won't stand in your way.

Doing a job is like selecting a mule, you can't choose just the front half xor the back half so when you ask me to do a job don't expect me to do it half-assed.

My articles on image processing might help in giving you code you can use to examine an image, a pixel at a time.

I have no idea what you mean. If you add a validating event, you need to first check if your control is of the right type, then cast it and call the method.

you need to create an interface which will contain a Validate() method, extend your controls(eg. inherit from Textbox,..) and also inherit from that "IValidate" interface.
In your custom textbox let's say, you may validate:

public bool Validate()
     {
         return !this.Text.Equals(string.Empty);
     }

After that, validate something like:

foreach (Control ctrl in this.Controls)
{
    if (ctrl is IValidate)
    {
        bool result = (ctrl as IValidate).Validate();
    }
}

Tab control

Hi,
I'm building my own tab control. I have classes with all of the lines and stuff I want to draw to make up the tabs and the outline to the control. But I'm just wondering because I'm finding it difficult to draw a tab each time a button to add a new tab is clicked, should I create a user control(for each tab) inside a user control(the actual tab control) or is there a good way to draw a tab using the class I have for that purpose each time the add tab button is clicked?
Sorry if this is hard to understand, I typed it out twice cos' the first time it was to hard for even me to understand Sigh | :sigh:

thanks

Is this through WPF or Windows Forms?

Also, are you building a new tab control more for fun, or to meet a need that the built-in tab control didn't meet?

A bit of both.

Why would you like to reduce the assembly's and executables.
What's the size they are now and what is the size you would like to have them?

I don't really know a lot about this. But I guess that you have many pictures in your app?
If that's true, then you should try and make the pictures smaller. If this doesn't work, I don't know either.

Nothing is built in to .NET as far as I know.

There are several third-party components that will talk to email servers, though. If you want to talk to an email program, I think COM/MAPI is still it.
