At last I got time to write one of important topic here.
How to send SMS from VB6.0 via Internet
When I got this work to implement in our project, first I got very excited but when I tried to search this topic on Internet via Google etc, I had to struggle a lot to find the correct method.
Well We can send SMS from VB6.0 by two ways
- By using Internet (this method is explained Here )
- By Using Mobile Phone (Not explained here)
After long time, I finally got chance to provide download link to demo project which is below
The downloaded file is rar compressed. In case you don't have software to extract it, just download wrar320 or higher version free of cost from the internet via Google etc.
Please note: You need some valid Developer API.
Please either contact company or create an demo account to get developer API from the site, I had mentioned Below.

Here I would try to explain HOW TO SEND SMS FROM VB via INTERNET
- The very first thing is that U need to contact to any SMS Providers (e.g. in India some are
- http://www.mysmsmantra.com/
- http://www.smscountry.com/ (click on Register now button at top)
- http://www.freesmsapi.com/ (click on Sign Up button at top)
- http://mirchsms.com/bulk_sms.html (please contact at no. provided at top or email at bottom to request to get trial sms api ). I also tested it very well, you may also refer my name to them.)
- Now get the Developer API from these SMS Providers either by purchasing account or if you want to test before purchasing then you can ask these SMS Providers to provide you a free trial account so that you can test their service)
- Below is one of the example of Developer API
- 'http://bulksms.mysmsmantra.com:8080/WebSMS/SMSAPI.jsp?username=demouser&password=399501089&sendername=DM&mobileno=919999999999&message=Hello"
- Now just use the following code in your VB program to send SMS
- Dim WinHttpReq As Object
- Dim sResult As String, strURL As String
- Set WinHttpReq = CreateObject("Msxml2.XMLHTTP")
- strURL="http://bulksms.mysmsmantra.com:8080/WebSMS/SMSAPI.jsp?username=demouser&password=399501089&sendername=DM&mobileno=919999999999&message=Hello"
- 'Replace the Message & MobileNo with the no to whom you want to send SMS
- With WinHttpReq
- .Open "GET", strURL, False
- .Send
- sResult = .responseText
- End With
- MsgBox "Status of Sent SMS is=" & sResult
- Some Important notes We should keep in mind while Sending SMS
- Check the Maximum Message Length that you can send as allowed by your SMS Service Providers
- Check whether you have to make your Message encode according to WWW standards, confirm it from your SMS Providers
- While sending data over internet/network, some letters can not be sent as it is, they need to be converted to send them to internet. e.g " &" can not be send as it, it needs to be converted to send it over internet.
- URL encoding converts characters into a format that can be transmitted over the Internet.
- For more information see following link
- http://www.w3schools.com/html/html_urlencode.asp
- Always Allow the access of your program to get connected with Internet which would be asked by the Firewall of your OS or Antivirus program else you could not send SMS
- As sending SMS may take time, you should do appropriate changes in your program to show user that your program is busy in sending SMS like change Mouse Pointer Shape from normal to HourGlass & after sending make it normal.

Below is a sample which I used in my project
Private Sub cmdSMSTest_Click()
'validate information
'Message(max 160 Chars)
Me.MousePointer = 11 'Hourglass
Call SendMySMS(myMob, myMsg, True, Trim(Me.txtSMSDeveloperAPI), Trim(Me.txtSMSMobileText), Trim(Me.txtSMSMsgText))
Me.MousePointer = 0 'Default
End Sub

'Here you write your code
Following is the sample code to test it--- but of course you need Developer API to use the code
Private Sub cmdSMSTest_Click()
'validate information
'Message(max 160 Chars)
If Me.chkSMSActivateService.Value = 0 Or Len(Me.txtSMSDeveloperAPI) < 1 Or Len(Me.txtSMSMobileText) < 1 Or Len(Me.txtSMSMessageText) < 1 Then
MsgBox "Please enter all setting values"
Me.txtSMSDeveloperAPI.SetFocus
Exit Sub
End If
Dim s As String
Dim myMob As String
Dim myMsg As String
s = "Enter Mobile nos separated by , then put @ now write your msg not more than 160 chars"
s = s & vbCrLf & "e.g 9971745868,9811994797@Hi this is test sms by ABM Infotech"
s = InputBox(s, , "9971745868,9811360935@Hi this is test sms by ABM Infotech")
myMsg = Mid(s, InStr(1, s, "@", vbTextCompare) + 1)
If Len(myMsg) > 155 Then
myMsg = Left$(myMsg, 155)
End If

Me.MousePointer = 11 'Hourglass

Now after learning it you can explore it in details to get more powerful options for your programs.
Best of Luck for Programming.
