Basic MSI Project - Custom Action - unable to get installed path

Hi,

I am using InstallShiled 2014 Pro.
I have created Basic MSI Project.
Added CustomAction in Basic MSI Project. ( Call a function in a Windows Installer dynamic-link library )

PFA: Screenshot for more info
https://i.imgsafe.org/1b4b0f3066.png

Added the new property in property manager.

Name - CustomActionData
Value - [INSTALLDIR]bin

When I executed setup.exe then "Install" custom action has thrown.
I am unable to get installed path.

shared custom action dll source code.
[CODE]
UINT __stdcall Install( MSIHANDLE hInstall )
{
TCHAR customData[MAX_FILE_PATH * 3];

DWORD len = sizeof( customData ) / sizeof( TCHAR );

UINT gp = ::MsiGetProperty( hInstall,
_T("CustomActionData"),
customData,
&len);
::MessageBox(NULL, customData, "Install", MB_OK);
if (gp != ERROR_SUCCESS)
{
return ERROR_INSTALL_FAILURE;
:Smiley SurprisedutputDebugString("gp != ERROR_SUCCESS");
}

return ERROR_SUCCESS;
}
[/CODE]



I got "[INSTALLDIR]bin" instead of "installed path" value in the message.box.

Re: Basic MSI Project - Custom Action - unable to get installed path

It's been a long time since I used C++ for a Custom Action. I always use C# these days. But see if this information helps

https://social.msdn.microsoft.com/Forums/windows/en-US/93ff80f2-3968-4a69-a123-e0bf079052f5/how-to-g...

The passing of [TARGETDIR] into CustomActionData seems to have been the trick in this case.

I hope that helps.

Re: Basic MSI Project - Custom Action - unable to get installed path

To pass a value as CustomActionData, you need to set a property that matches the name of the custom action. In your case, set the value of the property named CustomActions to [INSTALLDIR]bin.

I have shared sample source code of dll
[CODE]
UINT __stdcall Install( MSIHANDLE hInstall )
{
TCHAR customData[MAX_FILE_PATH * 3];

DWORD len = sizeof( customData ) / sizeof( TCHAR );

UINT gp = ::MsiGetProperty( hInstall,
_T("CustomActionsForInstall"),
customData,
&len);
::MessageBox(NULL, customData, "Install", MB_OK);
if (gp != ERROR_SUCCESS)
{
return ERROR_INSTALL_FAILURE;
:Smiley SurprisedutputDebugString("gp != ERROR_SUCCESS");
}

return ERROR_SUCCESS;
}[/CODE]



I have set CustomActionName = PropertyName in merge module.

Please verify my install sequences of custom action.


I have set all property as per your instruction but it is not working now.

Re: Basic MSI Project - Custom Action - unable to get installed path

The value of the property that matches the name of your custom action is available in the CustomActionData property within the deferred, commit, or rollback custom action. You need to get the value of the the CustomActionData property as your original code did:

[CODE]UINT __stdcall Install( MSIHANDLE hInstall )
{
TCHAR customData[MAX_FILE_PATH * 3];

DWORD len = sizeof( customData ) / sizeof( TCHAR );

UINT gp = ::MsiGetProperty( hInstall,
_T("CustomActionData"),
customData,
&len);
::MessageBox(NULL, customData, "Install", MB_OK);
if (gp != ERROR_SUCCESS)
{
return ERROR_INSTALL_FAILURE;
:Smiley SurprisedutputDebugString("gp != ERROR_SUCCESS");
}

return ERROR_SUCCESS;
}[/CODE]

Re: Basic MSI Project - Custom Action - unable to get installed path

Hi Hidenori Yamanishi,

please explain what is/are the meaning of commit & rollback in "In-script execution" in the custom action.

I also tried with deferred and immediate execution in "In-script execution" in the custom action but it unable to get installed path.

You said to me in the previous reply. (01-25-2017, 08:36 AM - Post Number - #3 )
CustomAction Name and Property key both are same.
I had applied to set same of CustomAction Name and Property key.
Example:
CustomActionName: "CustomActionForInstall"
PropertyKey = "CustomActionForInstall".

I also changed MSI DLL code.
[CODE]UINT __stdcall Install( MSIHANDLE hInstall )
{
TCHAR customData[MAX_FILE_PATH * 3];

DWORD len = sizeof( customData ) / sizeof( TCHAR );

UINT gp = ::MsiGetProperty( hInstall,
_T("CustomActionsForInstall"),
customData,
&len);
::MessageBox(NULL, customData, "Install", MB_OK);
if (gp != ERROR_SUCCESS)
{
return ERROR_INSTALL_FAILURE;
:Smiley SurprisedutputDebugString("gp != ERROR_SUCCESS");
}

return ERROR_SUCCESS;
}[/CODE]

Please read my (01-27-2017, 01:35 PM Post Number - #4) and tell me
what is/are wrong?

Re: Basic MSI Project - Custom Action - unable to get installed path

Deferred, commit, and rollback custom actions in Basic MSI and InstallScript MSI installations have access to only some of the built-in Windows Installer properties: CustomActionData, ProductCode, and UserSID. If you want a custom action to access any other properties during deferred, commit, or rollback execution, you can pass them as CustomActionData. You can do so by scheduling an immediate set-a-property type of custom action to set a property that matches the name of the custom action. The value of this property is then available in the CustomActionData property within the deferred, commit, or rollback custom action.
