Write an event handler for the DoubleClick event of the ListBox and there retrieve the value of its SelectedItem property.

Hi,

I'm trying to implement a textbox and a combobox in a menuitem. When the menuItem is shown, I want to have a textbox and a comboBox.

I already tried to construct a derived MenuItem and to override the onPaint, but got somehow stuck. I think I saw something like this on the net, but cann't find it again...

Any ideas/suggestions?

Dennis

You can draw everything via a GraphicsPath or perhaps there is some other way? Would be nice to know of the alternatives Smile | :)

I wanted to know how can I save what I draw. It crossed my mind serializing the graphic context but I don't know how to mark it as serializable. Or I thought may be I can save it like a bitmap file, but I don't know how to refere to it (what exactly to save)... Confused | :confused:

If you have any suggestions... please... I'd appreciate it! Smile | :)

Instead of painting everything in your OnPaint override for your Panel, move your drawing code to a method that takes a Graphics parameter. From the OnPaint override, pass the PaintEventArgs.Graphics property to that method. To save it to a file, create a new Bitmap and get a Graphics object from that (like Graphics.FromImage, for example). Then pass that Graphics object to your method. When the method returns, dispose your Graphics object, save the Bitmap, and dispose the Bitmap. For the OnPaint override, don't dispose anything since it will take care of it for you.

Difference between Directory and DirectoryInfo

Hi
I want to know the difference between Directory and DirectoryInfo as well as the difference between File and FileInfo.
Thanks..

Re: Difference between Directory and DirectoryInfo

The main difference is that Directory exposes static methods and DirectoryInfo provides instance methods for creating, moving, and enumerating through directories and subdirectories.
Read the documentation for this classes, there you find all information necessary Smile | :)

Right-click on the VS.NET toolbox and click Customize. Select the COM tab and find the Microsoft Web Browser component. Add it and click OK. Then drag and drop it from the toolbox to your form. Now you've got an instance of the Internet Explorer WebBrowser control. You can open files using WebBrowser.Navigate2, for example. There's other ways, though, just as there's other ways to add the WebBrowser component to your project.

Search CodeProject for "WebBrowser" for more examples and articles using the search textbox below the logo toward the top of the page.

Well, you have to tell it what "Program"...

Of course, leppie could have misinterpreted your initial question. Given the context of the forum and without additional qualification in the original posting, it reads as if you are asking: I am launching a console application from within another application, but how do I ensure that the Console window does not appear?

Welcome to the "Point-and-Click" programmer age.

I think that dude just didn't enable a feature in the compiler that allows
mind reading behaviour. Add the "/Cmr" option. It's a wonderful option that allows basically any code with undefined variables to compile without a problem, by just asking a telepathic question to the dumb a** programmer cutting and pasting something out of a internet forum.

Hello!

I want to learn how to work with IRC and make a IRC Client (very easy one) so I searched alittle and I only found a C# IRC Bot on c-sharpcorner:

http://www.c-sharpcorner.com//Network/IrcBotPH.asp

I downloaded the source code and got the two classes used. But how do I test this? There is no project in the sorce code only two .cs files. When I open them I can't run them. Can someone help me with what I need to do to make it run?

Create a project, add the two .cs files and then create an object of the IRCBot class?

Thanks in advance!

Either put them in a new project or use the C# command-line compiler to compiler them both. Type csc.exe /? on the command line (if %WINDIR%\Microsoft.NET\Framework\v<version> is in your PATH environment variable). Read the .NET Framework SDK for more information.

A quick google search on "TAPI detect silence" turned up the following result from the Microsoft Developer Network (MSDN) as the first result: http://msdn.microsoft.com/library/en-us/tapi/tapi2/linemonitortones.asp[^]. Simply P/Invoke the API and pass a tone frequency of zero to monitor for silence.

This is the C# forum, not the modem/hardware forum. Just like I (easily) found the article I linked above, so should you try to search for your answer. You can also check the OEM's web sites for information about their modems, which is the first place I would've checked.
