Hello there!

There’s the astonishing thing about human nature or should I say programmer nature that once you give someone a bit of excitement, they suddenly want more!

Hopefully that’s what happened when you read the first part of my setup tutorial and due to the wonderful response, I decided to put together all your wildest fantasies come true Part Two!

Top Tip: If you don’t want the user to see the sub-installer, use Shell [command_line], vbHide

Just make sure they’re put in the frmBegin’s cmdInstall_Click() code and followed by a DoEvents otherwise if the sub-installer is very memory consuming or is hogging the system’s resources, the system may go very slow or cause crashes.

If you remember, we added NetCheck to setup1.vbp in Part 1 of this article. You can use the ITC (Internet Transfer Control) to download a file from the Net if your user wants to. For example, you may give him/her a Command Button, which if clicked downloads some EXEs or other installers from the net.

If you’re not distributing over the Net, then it might be a problem to those without such a connection! So beware

We all know that you’ll go around customizing these forms and adding more of them here and there.

But if you’re going to get serious about customizing your setup, you’ll need more functionality. And that means more coding, more work, and more bloomin’ hassle… well no more!

Here, is a commented code dump of the best and most popular functions you’re likely to need in your setup program… put together specially by yours truly.

Just add the following code to a new module in your setup project:

When you run the P&D Wizard, it creates Setup.exe, the CAB files and a setup.lst file.

This setup.lst file is the data source of the setup program. As the EXE (setup1) is already compiled, it needs external data to work from. Setup.lst (or the BootStrap as Microsoft likes to call it) is just like an INI file to the setup program! It has it’s own macros and styles. In this section, we’ll learn a little about it, plus figure out how to edit the file…

First off, you should know about "macros", keywords in the setup.lst file which are replaced with something else when the setup program runs. This list describes the most common:

Macro Description
$(WinSysPath) System Folder of the OS
$(WinSysPathSysFile) System File installed in System Folder. This file will not be removed during uninstallation
$(WinPath) Windows Folder
$(AppPath) Application Folder where the software will be installed
$(AppPath)folder Use this to create folder sub-folder in $(AppPath). Any path can be created with this.
$(CommonFiles) Common Files folder. Generally combined with sub folder path.

Same as $(CommonFiles)System.

$(ProgramFiles) The program files folder on the user’s system.
$(MSDAOPath) Yes! The path for MS DAO installation! They thought of everything.
$(DLLSelfRegister) Self-registering .dll, .ocx, or any other .dll file with self-registering information (exports DllRegisterServer and DllUnregisterServer
$(EXESelfRegister) ActiveX .exe or any other .exe file supporting /RegServer & /UnRegServer command line switches
$(TLBSelfRegister) For Type Library File
$(Remote) Remote support file (.vbr)
$(Shared) Makes the file shared. If file is installed in Windows or WindowsSystem, it is automatically shared
$(Programs) Special for Program Groups

NOTE: Only $(WinPath) and $(WinSysPath) are valid in the [BootStrapFiles] section

WARNING: Never use normal path like c:somefoldermyfolder! This will not be good for your setup program on other systems.

Experimenting with the BootStrap file is easy. In fact, it is highly encouraged! You just might learn something! 😉

If you use additional DLL or OCX files in setup1.vbp, like a custom progress bar or other components, specify them in the [BootStrapFiles] section in setup.lst like this:

File7=@MyDll.DLL,$(WinSysPathSysFile),$(DLLSelfRegister),,5/10/99 12:00:00 AM,1384448,



Adding a comma can skip any parameter you don’t want to specify!

Now, let’s explore a few sections in the BootStrap file, with comments in red:



This is the title that appears in the pre-setup dialog.

SetupText=Copying Files, please stand by.

This is the text that appears in the pre-setup dialog.


This is the cab file name.


This is the EXE to launch for the setup program.


This is the uninstallation program.


This is the name of the temp folder setup will create in WindowsTemp for the temp files.


The number of cabs



Title= MySoftware

The title that appears on the blue washed background.


Folder where the software will be installed


Main application EXE


App to uninstall

The bootstrap is easy to edit. Try messing around in it! You’ll learn how easy it is!

NOTE: I covered a little of what can be done in the setup.lst file. However I highly recommend visiting or checking out VB’s documentation for more on the SETUP.lst file and ‘Packaging and Deployment’ in general.

If you’re using VB as a hobby, just learning the language or simply fooling around, no problemo. But when you go commercial, you’ll encounter lots of problems and barriers. From my experience the following are the most common, and their solutions are the easiest (to be used with my function module listed earlier).

I give thee the power use it well J

Internet Shortcuts

Sometimes you need to create an Internet Shortcut. Use the following.

CreateINetShortcut(strPath As String, strName As String, strURL As String)

StrPath is the path of the shortcut for example "c:windowsdesktopmynetshortcut.url"

StrName is the name of the shortcut for example "MyShortcut"

StrURL is the URL of the site for example ""

Using Encryption

Sometimes you have a little information you may want to keep secure. Use XOR Encryption/decryption like this:

XOREncDecFile(strKey As String, strInPath As String, strOutPath As String)

StrKey is your password for the file NEVER use anything except A-Z and 0-9! Its been known to cause problems.

StrInPath is the encoded/normal file

StrOutPath is the decoded/encoded output file.

It’s good if you don’t use the same path for both strInPath and strOutPath.

Windows 2000

Win2k and Package & Deployment Wizard: File dates are stored differently and errors can occur!

Of course, Microsoft sometimes forgets to report some bugs until after it has been fixed. Endless Reboot and Windows’ system file corruption are just are a few.

To prevent such problems, I highly recommend you install the latest service packs for both your OS and Visual Basic. Service Pack 4 of Visual Studio/Visual Basic solves the Endless Reboot problem and a few more bugs.

Wahoo we’ve finished the project already!

Ah, wasn’t it cool adding new interface elements, using encryption, sub-installers and a host of new functions? So go build that new setup EXE and have some fun!

If you need help or have comments, you can count on your setup guru. I can be contacted via that link way at the bottom of this page with an answer guaranteed within 24 hours or I’ll have my money back! 😉

Due to heavy demand of new features such as AVI, MP3, MOD and WAV support in setup programs, we’ll have yet another part of this great series. As you know, we give you what you want, so click the link below and tell us what you want and we’ll add it to the next part!

Till Microsoft goes down the drain, you’ll keep hearing from me.
