Created Your First Application For Nimbuzz

Here is a simple tutorial to connect to nimbuzz and send message.

Requirements:

• Microsoft Visual Basic 2010
• agsXMPP.dll ( Can be downloaded from here or check the attachments below)

Lets start!!

Firstly open Microsoft Visual C++ 2010 Express and Select New Project

Now you can see window like above picture. Select Windows Form Application and name it MyFirstApp , Then click OK

After the project is created, The next step is to add a reference to agsXMPP.dll which we have downloaded earlier (Take a look at picture below)

Select Browse and open agsXMPP.dll
And your form should look like the following,You can add more fields in form, My form is short because i want to make you understand easily.


Now Press F7 and select all code and replace it with the code below
