Im using the installshield automation interface to create an installation package. I was able to create Custom action using the follwing line of code:
ISWiCustomAction MSIExecUnInstallCustomAction = iswiProject.AddCustomActio("MSIExec_Uninstall_" + buildFile.FileName); // This action type value indicates "Launch Executable - " MSIExecUnInstallCustomAction.ActionType = 2;
My problem is when I open the installshield project I see a property for "Return Processing" in the created custom action, which I want to set to "Synchronous (Ignore Exit Code)". But I cant find this property in the automation interface. For example according the code above, there is nothing like MSIExecUnInstallCustomAction.ReturnProcessing ! How can I set this value through the interface. I appreciate any feedback from you. Thanks alot
Please see the MSI help topic "CustomAction Table", and the topics it links to; the ActionType field is a value combining the basic action type (DLL, EXE, script, etc.) with the return processing, in-script execution, and other flags.
Unfortunatly MSI crams all this information into really nasty bitmasks and the ISWiCustomAction object doesn't do anyone a favor by providing additional properties with enum arguments to effect the ActionType.
The easiest way to get through your current problem ( without reading pages and pages of SDK material ) is to stub out the CA in a dummy project and then look at what IS tells you is the MSI Type #. Then use that in the ISWiCustomAction.ActionType property as Robert suggests.
