The "ComPlusCompUpdate" Command

This command must be used within a ComPlusApp block.

The command is used to indicate which already existing component(s) (created with the "ComPlusComp" command) should be updated.

Between this command and the matching "/ComPlusCompUpdate" command you will use one or more "ComPlusProperty" commands to set the component properties. You can also place VBSCRIPT to operate on the component if you wish. The whole block is within a VB 'with' statement so you can operate on the component without knowing its name. Your code can use any of the following functions:

1. VbsCaCadGet
2. VbsCaCadGetValidate
3. VbsCaCadReplace
4. CaDebug
5. CaDebugPause
6. CaGetEnv
7. CaMsgBox
8. VbsCaPropertyGet
9. VbsCaRaiseError

This command takes these parameters to select which components are being updated:

• ProgID (optional)
  If you wish to select components to update by "ProgId" then use this parameter to specify it.

• CompareOP (optional)
  Normally when you specify a "ProgID" you wish to compare for equal ("="), this parameter allows you to alter this (the most common alternative probably being "<>"). This parameter is ignored unless "ProdId" was used.

• Where (optional)
  You wish to supply the full test expression which evaluates to true for components to be updated. Remember that the code is within a VBSCRIPT "with" block.

  Note that it would be trivial to add more parameters to this command to allow easier selection on things other than PROGID, let me know if you do.

If neither "ProgID" or "Where" parameters are passed then you wish all components updated.

EXAMPLE

This example shows an application being created. MAKEMSI is choosing the ID (a guid) and it will use the same one for any subsequent build. Both Application and component properties are being set.

;--- Include MAKEMSI --------------------------------------------------------
#include "ME.MMH"

;--- Define installation directory (INSTALLDIR) -----------------------------
<$DirectoryTree Key="INSTALLDIR" Dir="[ProgramFilesFolder]\SomeDirectory" CHANGE="\" PrimaryFolder="Y">

;--- I'm using any handy DLLs for this sample (I don't expect it to work...) ---
#define FILE_SRC_DIR       C:\Program Files\makemsi
#define SAMPLE_COM+DLL_#1  MakeMSI.DLL
#define SAMPLE_COM+DLL_#2  Reg4mm.dll

;--- Add the files (MSI components auto-generated) --------------------------
<$File RowKey="<$SAMPLE_COM+DLL_#1>" SOURCE="<$FILE_SRC_DIR>\<$SAMPLE_COM+DLL_#1>" Destination="[INSTALLDIR]\<$SAMPLE_COM+DLL_#1>">
<$File RowKey="<$SAMPLE_COM+DLL_#2>" SOURCE="<$FILE_SRC_DIR>\<$SAMPLE_COM+DLL_#2>" Destination="[INSTALLDIR]\<$SAMPLE_COM+DLL_#2>">

;--- Create properties for USERID/PASSWORD (could create dialog to ask user) ---
<$Property "USERID"   Value="Fred">   ;;Can override on command line if wanted
<$Property "PASSWORD" Value="abc">    ;;Can override on command line if wanted

;--- Define the COM+ Application --------------------------------------------
#data 'CaData' 2
    ;--- Pass installation directory and install time DLL names -------------

    "COMPLUS_DLL_1"     "[#<$SAMPLE_COM+DLL_#1>]"     ;;Want full install time location of specified file "RowKey"
    "COMPLUS_DLL_2"     "[#<$SAMPLE_COM+DLL_#2>]"

    ;--- Pass UserId and Password -------------------------------------------

   ;--- Create some application ROLES ---------------------------------------
   <$ComPlusRole "DennisBareisTestUsers" Description="Users for the DennisBareisTest test application" USERS="Everyone;Dennis">

   ;--- Add components (note that a single DLL can have more than 1 component!) -------------------------
   <$ComPlusComp DLL=^(*COMPLUS_DLL_1*)^>       ;;Filenames passed in Custom Action data (correct no matter where user installed them)
   <$ComPlusComp DLL=^(*COMPLUS_DLL_2*)^>

   ;--- Update the component(s) ---------------------------------------------
   <$ComPlusCompUpdate>          ;;Update all components (PROGID not supplied)
       ;--- Assign ROLES to the COMPONENT -----------------------------------
       <$ComPlusRole "DennisBareisTestUsers">

   ;--- Try some exporting --------------------------------------------------
