CLR means commaon language runtime for the dot net frame work.it is the frame work layer that resides above the operating system and handels/ manages the execution of the .net applications.our .net programs don't directly communicate with the operating system but through CLR.
OUT .NET APPLICATION--->>CLR--->WINDOWS OS
Please List Some Final Year Projects That Can Be Done Using Vb.net In The Application Level.
You can go for internet control of robot.
1. use chips:- at89c51 microcontroller, l293d motor driver n max232 converter (for robot)
2. using vb.net, develop the gui n use winsock programming for sending photos on internet.
3. use mscomm programming in .net to move the robot in a wired connection with the comp.
4. u can also use Enbedded C for microcontroller programming in place of assembly.use keil compiler for that n its available for free on internet.
5. attach a cam to robot, move it n transfer the photos captured to the client over internet.
How Can We Get The Contents Information That Are Displayed In A Web
browser control in vb.net.
Suppose If We Display The "c:\" Or "d:\" Of The Computer In A Web Browser And We Want To Get Any Folder Details But Not Ny Rigth Clicking The Folder. How To Do That Plz Help
I think you want the openfiledialog, unless your saving, then savefiledialog. Add one to your project. the simplest usage allowing you to use in any fashion would be
Dim OPEN as New Openfiledialog
open.showdialog()
then when you hit open on the dialog, you can pass that information such as
Dim a as string
a = open.filename()
a will then = D:/Filename.smt, or whatever its real directory is Ofcourse there more recomended approaches to this method, but that should get you somewhere.
What Is The Base Class Of .net?
System.Object is the base class of .NET
It Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate superclass of all classes in the .NET Framework; it is the root of the type hierarchy.
Whats The Difference Bt. .dll Extension And .exe Extension Files?
DLL : It is an inprocess server and runs in the same memory space as client application. Problem with dll is if any error comes in dll, whole application gets crashed.
Exe : It is an out of process server and rus as independent application in seperate memory. If error comes in exe, it does not affact the client application.
How To Send Xml File On Server Using Http Protocol?
Through SOAP Protocol.
How A Rotate A Control (rotation Like Shapes Are Rotated In Ms Powerpoint ) In Vb.net?
we can use adrotator control to use like powerpoint presentation.
How Can I Extract The Formated Word(bold,italic,underline,font,color Etc) From The Msword File.?
using CommonDialog class
eg
the code to invoke the default font dialog box by using the FontDialog control is given below
private sub displayfont_click(byval sender as system.object, byval e as system.eventargs) handles displayfont .click fontdialog. showDialog()
textbox1.font=fontdialog1.font
end sub
the code to invoke the default font dialog box by instantiating the fontdialog class is
dim fdialog as new fontdialog()
private sub displayfont_click(byval sender as system.object,byval e as system.eventargs) handles displayfont. click fdialog. showDialog()
textbox1.font=fontdialog1.font
end sub
Differences Between Vb.net And C#, Related To Oops Concepts?
1. C# uses Must not Inherit, VB.Net uses sealed class
2. C# uses Internal, VB.Net uses Friend
3. VB.Net uses with events and end events
4. C# uses abstract and VB.Net uses Must Inherit
Can U Able To Get The Xml Document In Crystal Report If Yes How Its Possible?
Yes. You have to convert XML to dataset.
