Read AssemblyInfo file in runtime

Sometime we need to read the information which is there in the assemblyinfo.cs file for about formbox. I googled in internet, finally found an answer.

Assembly currentAssembly = Assembly.GetExecutingAssembly();

AssemblyName assemblyName = currentAssembly.GetName();

//If only need version information then use.
assemblyName.Version.ToString();

//Copyright information
AssemblyCopyrightAttribute copyright =
AssemblyCopyrightAttribute.GetCustomAttribute(currentAssembly,
typeof(AssemblyCopyrightAttribute)) as AssemblyCopyrightAttribute;

like this you can get all the attribute information from assemblyinfo.cs file.

AssemblyVersionAttribute
AssemblyProductAttribute
AssemblyDescriptionAttribute
AssemblyCompanyAttribute
AssemblyTitleAttribute

If you need any more information feel free contact me at any time.

Checkable group box

Some days ago, i have requirement to design the UI in such way that it should contains group box and chack box on top it. so i thought it's very simple somebody might have done it. i searched on internet, i couldn't find a control. so i decided to create a control which will contains check box on the top corner of group box. It has features like ordinary checkbox if click on checkbox then automatically disable/enable the controls within the group box. if you want some action should be performed while clicking on groupbox then subscribe of for checkbox click event also.

Because of blog file upload constrains i am not able upload file here. but i am telling the steps which needs to be done and code.

1) Implement a Groupbox control
2)Override paint event for drawing of checkbox
3)Override mouse down event for changing the status of check box.

Here my control code.

Just create c# file and copy paste above code, compile and use it in your application.

Feel free contact me if you need any more information and also i am very glad accept your suggestion.
