Do I need to register Dlls

[Maoz]

Hi, I created a new Active-x with Visual C++ 6, MFC.
This Active-x is using 3 of my dlls.
I'm using the Active-x on my site with "CODEBASE".
When I'm loading my site from a system that owns MFC, it works perfectly, but when the user doesn't own it, I'll get an error on the installation.
I have 2 questions:
1. Do I need to register the 3 dlls on the user system?
2. what's is the current problem in my INF file:

my INF file:
-------------------------------------------------------
[version]
; version signature (same for both NT and Win95) do not remove
signature="$CHICAGO$"
AdvancedINF=2.0

[Add.Code]
Funk_AX.ocx=Funk_AX.ocx

amsgdb.dll=amsgdb.dll
EFunkDll.dll=EFunkDll.dll

; These are the necessary supporting DLLs for MFC 4.2 ActiveX Controls
mfc42.dll=mfc42.dll
msvcrt.dll=msvcrt.dll

[EFunk_EffectsDll.dll]

; dependent DLLs
[msvcrt.dll]
; This is an example of conditional hook. The hook only gets processed
; if msvcrt.dll of the specified version is absent on client machine.
FileVersion=4,20,0,6164
hook=mfc42installer

[mfc42.dll]
FileVersion=4,2,0,6256
hook=mfc42installer

[olepro32.dll]
FileVersion=4,2,0,6068
hook=mfc42installer

[mfc42installer]
file-win32-x86=VALUE=

http://activex.microsoft.com/controls/vc/mfc42.cab

; If dependent DLLs are packaged directly into the above cabinet file
; along with an .inf file, specify that .inf file to run as follows:
;InfFile=mfc42.inf
; The mfc42.cab file actually contains a self extracting executable.
; In this case we specify a run= command.
run=%EXTRACT_DIR%\mfc42.exe
-----------------------------------------------------------
This is the log file I get when the user doesn't own the MFC:

I think the problem is you did not specify a destination directory for those 3 DLL's, so they are not being copied to a directory which is in the user's search path.

The three warnings are just telling you the DLL's don't contain any COM objects, so no need to register them as such. To get rid of these warnings, put a "RegisterServer=no" in the [*.dll] sections for those DLL's (as the warnings suggest).

Then when the error is displayed, it is because the Funk_AX.ocx did not open properly, probably because it tried to load those three other DLL's and could not find them in the search path.

Try adding a "DestDir=11" in each of the [*.dll] sections. The "11" means the Windows system folder. For reference see this MSDN page.

 

[russland]

could you explain briefly what the search path is? i'd appreciate. thanks

so here's error log from ie when trying to load and initilize the cab file. ImageMagickObject.dll fails to register (funny thing is that i can do it manually using 'regsvr32 c:\ImageMagickObject.dll' and then then webcontrol runs just fine)

Error code 0x8007007E means "The specified module could not be found." I think the control tried to load one of the three DLLs installed right before it, and couldn't find it, because they are installed to destination "0", which is the downloaded component cache directory. This is probably not in the default search path.

Try setting DestDir=11 for those other 3 DLLs too.

By "search path" I mean all the directories listed under your "Path" environment variable. Go to the control panel, double-click the "system" icon, select the "Advanced" tab, and click the button near the bottom of the dialog, marked "Environment Variables". Now look for a variable named "Path". This will be a semi-colon delimited list of paths that Windows searches through when looking for EXEs and DLLs.
