List Installed Programs
Hi,

I need to put all of this in a listbox.

what´s the better way to get this?

Thank you

Test For Installed Programs?
Hi all,

I was wondering if someone could help me out. I have a program which sometimes displays .swf files and therefore needs the computer it is installed onto to have shockwave flash installed on it.

The problem is that some of the computers the program will be installed onto will not have shockwave flash on it. I was just wondering if anyone knew how to test the host computer and see if shockwave (any version) is installed on it. So if the computer does not have it installed, I can cause the program not to display these files and therefore get the program to run.

Cheers

John

List Of Installed Programs?
Hi
Can anyone tell me how to get a list of installed programs in VB6? The listed programs will later be compared to another list of programs, but this (I hope) will be easier so I can work it out by my self.

I found this, but it's not for VB6
http://www.appdeploy.com/tips/detail.asp?id=128

I know this isn't the easiest application to start with as I'm very new to programming, but I really want to make something useful rather than exercises. Thanks for your time

Do Vb Programs Run On Computers Without Vb Installed
or does the computer need to have something installed first? would a program i make on vb work on any computer

Checking If Certain Programs Are Installed
How do I check if the following programs are installed on a PC...?

MDAC 2.8
.NET Framework 1.1
MySQL ODBC 3.51 Drivers

Does anybody have code on how to do this, or an idea if I can check if these programs are installed.

Query For Installed Programs
In vb6, can I query the pc for a list of all installed programs like MS office, MS project, Winzip, etc?

Detecting Installed Programs
I'm trying to write a program that will detect which programs are installed on a computer (we have about 1,500 comps on our netowork), and write the information to the registry for inventory purposes. If someone could help me fill in the pseudo I would much appreciate it:

If(Winzip = Installed)
Print "winzip is installed".
Endif

Another (and better) way would be to get the entire list of installed programs (like the list in Add/Remove in the Control Panel) and parse it into the registry, is there a way to do this?

Re; Installed Programs From Registry
Howdy.

Just wondering is the list of programs installed on the $current$ computer always listed here :

And if so, is there a way of enumerating through that list of crap ?

How Can I Search For Installed Programs
how can i let my aplication search for all the installed programs

and if it find a program that it adds to a listbox?

Get Installed Programs List
Hi - Is there an API to get the list of programs in the Add/Remove Programs list.

(Or any other way to determine if a program has been installed under Xp and Vista?).

HKEY_CURRENT_USERSoftware? (Some programs add reg entries when just being run after being unzipped (not installed) - e.g., Audacity)

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall? (is this reliable?)

Program Files (could be anywhere)?

I am told that installers such as Wise must be able to access this data. Any ideas?

Thanks - Ron

Environment Variable For Installed Programs?
I'm trying to find out what hotfixes are installed on a machine, and search the values of whatever is called, to find a certain patch or program that's installed. (Find out what's listed when you pull up the Windows Application Wizard.)

I've been using PSinfo.exe (by Sysinternals), and calling it with SHELL. I'm trying to output it to a text file using ">", but it's not working. If you know how to call some sort of environment variable to find out what's installed, straight from VB code, that'd be GREAT. Below is what I've been trying.

Code:
Dim Text As String
Dim Text2 As String
Dim Machines As Integer
Dim HotFixes As Integer

Machines = FreeFile
HotFixes = 2

Do Until EOF(Machines)
Line Input #Machines, Text
Shell "\rm2ks15exi658d\$ oolspsinfo.exe -h OS \" & Text & " > C:patcheshotfixes.txt", vbNormalFocus
Open "C:patcheshotfixes.txt" For Input As #HotFixes
Text2 = Input(LOF(HotFixes), #HotFixes)
If InStr(Text2, "KB841356") Then
End
Else
If InStr(Text2, "KB871250") Then
End
Else
End If
End If
Loop

Check If Dll Is Installed
I'd like to be able to check if uxtheme.dll is installed. It's only for a minor cosmetic thing so I don't want to go overboard with code that tests loads of things. I'm using "IsThemeActive" but on win 2000 the app won't start and gives an error:

"uxtheme.dll missing" or something like that. Someone tested it for me I don't have win 2000.

Is there a simple way just to check if uxtheme.dll is present? Or is there another (short) way that doesn't require lots of declarations and other code?
Many thanks for any help.

Check Whether SQL Is Installed
Hi Everyone

here is my problems

1 While installing a program I want to check whether MSSQL 7 or above is installed in the machine.If it is installed the setup must continue or if it is not installed the setup must prompt the user
to install MSSQL and the setup must exit

2 If MSSQL is installed I want to check whether servicemanager is running and if it is not running the user must be prompted to start the service manager.

3 After the Servicemanager is on I want to run the scripts intended for creating the database and tables.

4 When the program starts the user will be prompted for the SQLSERVER name and the value will be written to the registry. In the future if the name is changed I want to make changes to the registry values accordingly

Let lFound = True
End If
Next aFont
If lFound = False Then
Call MsgBox("Please install the font kixbrg__.ttf", vbExclamation, "Font not installed")
End If

Anyone knows what I'm doing worng? Or is this not the way I should do this?

Check For Installed Excel
Is the only way to check to see if excel is installed in with the CreateObject function. I would like to place a routine in the Form Load event to check if the computer has excel and then set the enable on a command button. I am also using a template and adding data to this template through VB6. I have to keep the template saved with a certain cell having the focus or the data gets displayed wrongly when VB6 writes the file. Can someone point me to a place where I can set the focused cell through VB6

Check If Right Library Is Installed
Hi

I am writing a dll that uses a lot of other programs on the computer. My problem is that how can I check that the right program/library is installed? The only way I can come up with, is to crate an instance of the program and test if there was an error (see sample code). The problem with this approach is that it takes forever to start up the program. Does any of you have another way to do this check?

Sample code;

Code:
Public Sub testVisio()
On Error GoTo ErrHandler
Dim app As Visio.Application
Set app = CreateObject("Visio.Application")
state "installed"
Exit Sub

ErrHandler:
state "notInstalled"
Err.Raise Err.Number, "test Visio", Err.Description, Err.HelpFile, Err.HelpContext
End Sub

Check If There Is SQL-Server Installed
Hi there,

I need to check if there is SQL-Server installed in a determined PC, and get the complete path to its DATA folder (for create new database). I was thinking about to check all folders of the harddrives, and look for any specific file of MSSQL, but I guess that should have some easier and quicker way to do that...

Anyone has some clue about that?

PS: I believe that the idea should work with any other application, uh?

Thanks!

Tricky Check: Dll/ocx Installed?
Hi all!

I want to use msWinsock-control. No problem! ;)
But I don´t know whether the customer who gets the app distributed has this included component installed (in this case: mswinsck.ocx).
How can I check this before starting the application and raise an ugly windows/vb-error.
Do I really have to read the reg to get the system-folder and then check via fso, whether the file exists? Then it could be that the fso does not exist (Yes - we already had customers with this LITTLE problem )

I am sure you know a beautiful solution and thank you in advance

best regards

Check Registry For Installed Printers
Hello, I haven't used Visual Basic in several years, and Im trying to make a program that will read the users registry for the currently installed printers and then pop up a webpage with those printers listed on it. Is this possible? I have found this link :

http://www.ozgrid.com/forum/archive/...p/t-10081.html

Apparently it is in Word VBA, but i dont strictly understand all of it. Is word vba syntax the same as visual basic? Does this link describe what I need? If so, could someone maybe explain it to me?

Any help would be greatly appreciated,
Luke
