I am trying add databinding to one of my textbox. When I click on "Text" under "DataBindings" section in the property grid, I get an error says "Object reference not set". Any idea to solve this ? I have tested it with another project and it works correctly. Any ideas ?

Hi,
There are several reasons which can cause this error, few of them are:
1) Some classes have constructors; therefore you need to properly instantiate it.
2) Bad scoping.
3) MAKE SURE that you've explicitly declared the variable, and don't forget to use the appropriate scope.
Since you are not getting the same error in another project therefore, I try to match the property settings of both project and manipulate them to see if this helps.
Hope this helps.
Have a nice day.

I know when this error occurs and I could have corrected it if it was my code. But this is happening with VS2005. As you said, some properties will be invalid. Thanks anyway

Hi,
Please take to through the following article.
http://www.codeproject.com/KB/miscctrl/CustomAutoScrollPanel.aspx[^]
This article show how to customize a System.Windows.Forms.Panel to use effectively scrollbars with the AutoScroll property. In this example, you can change enable or visible property of each scrollbar of the panel, receive scrolling events, send events to the panel and change and receive the positions of both scrollbars.
Hope this helps

I had used UltraColorPicker control to show the color in a column in listview. But while selecting the color it is showing some relevant numbers instead of color name for few colours in Custom tab. Did i miss any settings here..... ? Any one help me....
Thanks in advance

What is ultracolorpicker ? I have no idea. I'm sure many others do not either. So, how can we help you ? Do the ultracolorpicker people not have a website ?

Hi..
I Need to Draw a sine wave on the Form, based on the X and Y values. I have stored those values in List variable..
How can i draw a continuous sine wave using GDI+ using C#
|
|
|

Best bet is probably Graphics.DrawLines to draw straight-line segments between the points.

You do this using DirectX filters, which you drop into the stream. There's plenty of examples on the web, did you try google ?

Hi,
I have created my own DLL as a class library & I am wanting to include this in a C# windows application.
In my windows app & I add a reference to this dll easily, but when I try and add my using statement it doesn't appear in the list 
I know this is going to be a really simple prob - but I just cant see the wood for the trees!
I would be grateful if anyone can help.
Thanks
Janet

Have you tried just typing the namespace in the using statement manually and building the application. I'm thinking that intellisense may not be working correctly.
Alternatively, you could attach the project that creates the class library to the same solution that holds your windows application and add the reference by the project than manually through the assembly.
|
|
|
|
|
Thanks. Once I just added the namespace & built the app I didn't get any errors, so I knew then that I had made an error in the DLL!
The error was - I had given the dll class name the same name as the namespace - durr!
Cheers
