What am I wrong with commandline argument and Basic MSI Project?
I follow the step of the example. --------example----------------------------------- To access SUPPORTDIR through a deferred InstallScript custom action:
1. In the Custom Actions and Sequences view, create a set-a-property custom action (type 51) called GetSUPPORTDIR . Configure the Property Name, Property Value, and Install Exec Sequence settings for the custom action as follows, and leave all of the other settings blank. * Property Name: DisplaySupportDir * Property Value: [SUPPORTDIR] * Install Exec Sequence: After InstallInitialize 2. In the InstallScript view, create a new function called DisplaySupportDir. 3. Add the following code to display a message box containing the value of SUPPORTDIR: {{{ function DisplaySupportDir(hMSI)
STRING supportDirPath;
NUMBER supportDirPathBuffer;
begin
supportDirPathBuffer = MAX_PATH;
if(MsiGetProperty(hMSI, "CustomActionData", supportDirPath, supportDirPathBuffer) == ERROR_SUCCESS) then
SprintfBox(INFORMATION,"Deferred Execution","The value of SUPPORTDIR is %s",supportDirPath);
SprintfBox(INFORMATION,"Deferred Execution","The value of InstallScript's SUPPORTDIR is %s",SUPPORTDIR);
endif;
end; }}} 4. In the Custom Actions and Sequences view, create an InstallScript custom action called DisplaySupportDir. Configure the Function Name, In-Script Execution, and Install Exec Sequence settings for the custom action as follows, and leave all of the other settings blank. * Function Name: DisplaySupportDir * In-Script Execution: Deferred Execution in System Context * Install Exec Sequence: After GetSUPPORTDIR --------example------end--------------------------
but, I cant see `supportDirPath` contents. (I just see `SUPPROTDIR` property variable).
what should I check the above sequence? or that need ServicePack2 or some special options?
Take a look at a verbose log file, searching for SUPPORTDIR and the names of your actions. This should help you diagnose if any of the following possible explanations apply:
There is no value for the SUPPORTDIR property (perhaps your project doesn't have any support files?)
There's a name mismatch, and your deferred action is not getting the CustomActionData specified correctly
Something's wrong with the action itself (although on quick inspection the code looked fine)
