Private Declare Function PostMessage Lib ' user32.dll' _ДЄlias ' PostMessageA' ( ByVal hwnd As Integer, ByVal wMsg As _ Here is the component to send and build the string: Then, we raise en event to indicate that a new string was received successful. In this article, I will introduce a simple way to send strings to another application running in the same computer, by using the SendMessage function the concept is: ConceptДЇor security reasons, there's no way to directly access another process' memory in VB.NET, so if we want to send a string to another application, what we can do is encode the string to a byte array, and send each member in the byte array sequentially at the end of the sending session, we need to send a terminator byte.ДЄt the receiving end, we put every received byte into a byte array until the terminator byte is received. Microsoft introduced a way to connect different applications by using Remoting it's suitable for mass communication, but if we just want to send some simple messages, it will use more resources to develop and run it on the computer.

But in VB.NET, when we declare the Win32 API function SendMessage, it does not accept ' Any' as data type, which means we can only send 32 bit integer parameters by using the SendMessage function in. In VB6, we can easily use the SendMessage function to send a wm_datacopy message, because we can define lparam as Any.

Sometimes, we need to communicate with other applications, such as send and receive strings.
