I followed the tutorial couple of days ago and got relativly same issues.
At the end after some googling I added: extern "C" _declspec(dllexport)
in the definition of the function I use like:
extern "C" _declspec(dllexport) UINT __stdcall ConfigForH2(MSIHANDLE
hInstaller){
...}
Also if you want to use properties from the UISequence you have to add
another CustomAction which will be run BEFORE the actual CustomAction to
set up the Properties. eg.
--
<CustomAction Id ="ExporterConfiguration.SetProperties" Return="check"
Property="ExporterConfiguration"
Value="InstallLocation=[INSTALLLOCATION];Username=[UserIdBox];Password=[PasswordBox];"
/>
<CustomAction Id ="ExporterConfiguration" BinaryKey="CustomAction"
DllEntry="ConfigForH2" Execute="deferred"/>
And when I call the Custom Actions:
<InstallExecuteSequence>
<Custom Action="ExporterConfiguration.SetProperties"
Before="ExporterConfiguration"><![CDATA[NOT Installed]]></Custom>
<Custom Action="ExporterConfiguration"
Before="InstallFinalize"><![CDATA[NOT Installed]]></Custom>
</InstallExecuteSequence>
I hope this is useful to you.
