Smart COMM VB6

1. Driver installation.

The terminals are connected to POS through USB port, it is necessary to install the corresponding drivers since Windows needs them to detect the device. To install the device drivers it is necessary to unzip the file USBDriver_V2.22_20180726.zip, run the installer USBDriver.exe and follow the instructions on the screen.

Once the drivers installation are done, Windows will detect our Smart Pin Pad device and assign it to a working serial port. To watch the assigned serial port, it can be viewed on Control Panel, in the Hardware Devices section, under the Ports (COM & LPT) menu.

2. POS demo.

There is a Demo POS to simulate the transactions of Sale, Cancellation and Reprint.

Download the Demo “vb6-connector-demo-dev.zip” from the drive unzip make the references to the dll and tlb depending x64 or x86 architecture as indicated in point [ 3.- Component installation.](https://docs.netpay.com.mx/docs/smart-comm-vb6#3-instalación-e-integración-de -components)

3. Installation and integration of components.

3.1 Installation of components.

To integrate with the terminal, the following files are included, which must be imported into th POS project. The DLLs have as Target .NET 3.5 Framework or higher.

NetPayConnect.dll (Connector for Smart PinPad DEV terminal).

NetpayConnect.tlb (Library required for Visual 6.0).

The dll files can be downloaded from the following drive folder “NetpayConnect_v1.1”:

📘

Note.

Depending on the type of development, it is necessary to verify if it is in x64 or x86 architecture since the corresponding dll must be added.

Steps for the installation of the components.

Open Windows Command Prompt (CMD) in Administrator mode

Execute the line --> cd C:\Windows\Microsoft.NET\Framework\v4.0.30319 (Path where the netframework is installed)

Followed by --> RegAsm.exe "C:\Utilities\NetPayConnect.dll" /tlb:NetPayConnect.tlb /codebase

Where C:\ Is the path where the necessary files to install (dll and tlb) are located.

📘

Note.

If for some reason the assignment of the .tlb file does not work, a new one can be generated by locating the .dll file with the following commands:
Execute the line --> cd C:\Windows\Microsoft.NET\Framework\v4.0.30319 (Path where the netframework is installed)
Followed by -> RegAsm.exe "C:\Utilities\NetPayConnect.dll" /tlb /codebase

3.2 Component integration.

The NetpayConnect.dll component is a library that can be integrated into any Windows-based development language that supports this type of library. Currently the library is compiled for x86 platforms in order to work on x86 (32-bit) and x64 (64-bit) platforms, depending on the case.

Reference DLL to Visual Basic6.

Open the Project Tab and click on References. On the References screen, click on the browse option and search for the file with the tlb extension once added, select the NetPayConnect Reference from the list.

4. Library integration.

The SmartPinPad DEV application already contains the functionality by default or Method SendData()
The library contains a class called Operator which is used to call the methods.
The SendData() method makes or processes Visa, MasterCard and American Express branded credit and debit card payments.

📘

Note.

In the general class the line is added to be able to use the dll. In the case of Visual Studio 6, the .tlb is integrated

Example of how to use the dll once it is referenced and installed on windows:

Dim conector As NetPayConnect.Operator 
Set conector = New NetPayConnect.Operator

The parameters received by the Operator method are listed below (It defines the type of transaction to execute, it can receive the following values):

Field

Description

setAmount()

The amount to be collected is assigned. Receives a value of type Double (only accepts 2 decimal places).

setMSI()

The number of months without interest is assigned at the time of processing the transaction.
By default, the value 0 (without months) is sent.
Possible values that it accepts: 3, 6, 9, 12, 18.

setFolio()

The personalized folio to be used in the Ticket is assigned.

sendData()

Once the minimum amount has been assigned, this method is called to process the transaction on the PinPad.

sendPrint()

Reprint a transaction (requires orderId). To perform a test transaction we must use at least the setAmount() method to place the amount to be charged and process the transaction with the sendData() method.

ReceiveData()

After executing a send type method, the ReceiveData() type is activated, which activates the reading of the port. This returns a reply message in text.

4.1 Reading the authorization request response.

After executing the SendData() method, the connector will send the transaction to the Smart PinPad DEV which processes the transaction and will return the parameters that show the result of the operation.

To read the transaction response, the component returns a boolean value indicating true if everything was processed successfully and false otherwise.

The process for processing a transaction is as follows:

  1. The point of sale assigns the necessary parameters, SetAmount.
  2. The point of sale executes the SendData() method.
  3. The connector activates communication with the Pinpad device and requests that the customer's card be swiped, inserted or contactless on the Pinpad.
  4. Upon receipt of the card data the PinPad processes the transaction.
  5. The point of sale reads the transaction return variables by calling the RecieveData() method.
  6. The GetResponse() method is given, which returns an object of type data:

The variables that can be read when the GetResponse() event is executed, will obtain a response type object which contains an idReport property and another object which contains all the properties of the sale.

idReport: Contains the type of object that can be the following:

EARRING

Example of code to obtain the data of the sale:

Dim conector As NetPayConnect.Operator 
 Dim ResponseData As NetPayConnect.Response 
 Set conector = New NetPayConnect.Operator 
      conector.SetAmount CDbl(Val(txtAmount.Text))
      conector.SetTip CDbl(Val(txtTip.Text))
      conector.SetFolio (txtFolio.Text)
      conector.SetMSI (Val(cmbMsi.Text))
     Text1.Text = ""
     lblResult.Text = ""
    Dim resultRead As String
    resultRead = conector.sendData()

Set ResponseData = conector.GetResponse() if ResponseData is Nothing Then Exit Sub  	if ResponseData.idReport = 1 then  
 	 	‘ obtiene datos de la venta 
 	Else if ResponseData.idReport = -1 then 
 	 	‘ ocurrió un error en la venta 	 
 	End if   	 
  	 
End if
