IEnumerator only supports moving in a logically forward direction. Further, the Reset() method is optional and may not be supported by all instances of IEnumerator.

Perhaps the Scribble[^] sample will help you get started?

I haven't really looked at Paint.NET source but I can imagine there's a lot to learn.

Hello,
I have a tab control and on one of the tabs I have the ListView control that has the ItemCheck event. When application starts, the tab that contains the ListView does not have focus. But if I select that tab, the ItemCheck event fires all the time, but only the first time I select the tab. If I start switching the tabs the event does not fire anymore.
What's going on? How can I suppress that event firing for the first time?
Thank you.

According to MSDN, "the ItemCheck event occurs when the check state of an item changes or when the CheckBoxes property is set to true". Perhaps the first instance of the event occurs when you set the list view's CheckBoxes property?

I´m working with large xml files(about 100MB) and what I have to do is:
- first validate the xml file against a schema
- then insert data from the file to a database
What is the most efficient way to do this? Can anyone help me with this?

Efficient at 100 megs may not be that big of an issue. System.Xml.XmlReader is the fast method for reading. System.Xml.XmlValidatingReader will validate.

Using a DOM reader like XmlDocument is the standard way to read/edit xml documents (at least I think...) because you can use XPATH and stuff. However, if you read a 100MB xml document with a dom reader your program will be suddenly using 100MB of ram. I'm pretty sure you don't want that...

Yeah, Ennis Ray Lynch, Jr. is right, you want to use a sax based reader like XmlReader because a DOM based reader like XmlDocument would be too slow.

Thanks I´ll try it

The following link should be helpful for the validation part: Validating XML Data with XmlReader[^]

Using Visual Studio 2005, I'm creating an application with floating tool bars similar to that of Photoshop (or most any application with floating tool bars) that share focus amongst each other. I have my tool bars in separate forms, and I call form.Show(ownerForm), to display the toolbar, where ownerForm is the main application's form. The problem is that only one form, the application's main form or the tool bar, can have focus at a time. Is there a property or method I can call to give focus to both the tool bar and the application's main form at the same time?

i think if you develop the toolbar as a usercontrol not as a frame it will give you an advantage. cz if you did it as a user control and add it to the first frame it will be as any normal control in your frame. this will allow you to have a double focus. you can drag and drop from it and .........
i am not very sure about the idea i gave you but i think it will be a starting point for you.
good luck

Setting the SelectedIndex property to 1 deselects the currently selected item (if any). Use a value of zero to select the first item.

Hi,
Setting the SelectedIndex to -1, will lead to a blank text being displayed as the first item of the dropdown combo. Instead try with setting SelectedIndex = 0;
this.dropdown1.SelectedIndex = 0;
might help u out.
Thanking you in Advance

Hi
I developed application using VS2005.I have few questions about UI,
1. I have used the icons provided by the VS2005 to resize the buttons and text boxes.But,now I could not move the controls.Its very hard to even insert or resize a new control, what could be the problem?
2.I have used tabControl with tabPage collection,I changed the backcolor of tabControl , but tabpage buttons still system-color,I am not able to change their color or nor resize them.
3.I have developed an instant messaging application, can I prompt the user using mini icons at bottom of PC when the message comes? how to do that?

1. ?
2. You can't change the colour/ size of the tabs by default. There are some extended TabControl's about. Google it.
3. You'll want the NotifyIcon control for this.
