Many Australian companies use RedCoal SMS texting services to send SMS texts to mobile phones from computers.

RedCoal supplies an API for its MIDA technology with VB and C++ examples but no Delphi code.

I have created a Delphi demo with code using Delphi 2007, which you can download and use free of charge.

Of course, to actually use the SMS text service, you will need to download the SDK from RedCoal which includes a serial number generator which provides the serial number for your application, and you will need to email them for a trial SMS Key (developer’s trial lasts 1 month then there is a one off royalty free developer’s license of $A695).

Finally, your client will need to open an SMS text service account with RedCoal to pay for the actual SMS texts sent (17-22c per SMS for pre-paid).

Post script:

If you deploy this in an organisation which uses a proxy server for internet, then you will need to detect this and set the HTTPWebNode.proxy property which must be in the format server:port (fortunately, this is the format used in Windows registry as outlined below):

for example:

RedCoalRIO.HTTPWebNode.Proxy := GetInternetProxy;

function GetInternetProxy:String;
var reg:TRegistry;
begin
result := ”;
Reg := TRegistry.Create;
try
Reg.RootKey := HKEY_CURRENT_USER;
if Reg.OpenKey(‘\Software\Microsoft\Windows\CurrentVersion\Internet Settings’,False) then
if Reg.readBool(‘ProxyEnable’) then
begin
Reg.CloseKey;
if Reg.OpenKey(‘\Software\Microsoft\Windows\CurrentVersion\Internet Settings’,False) then
Result := Reg.readString(‘ProxyServer’);
end;
finally
Reg.CloseKey;
Reg.Free;
end;
end;
