Determine If Acrobat Reader Is Installed On User Computer?
Mar 8, 2009
I am creating a project with VB2008 Express Edition. The end result will be a CD containing tech manuals in pdf format which will be accessed via various buttons on a form. I am going to include Acrobat Reader Redisributable on the CD which the user can install by pressing a button on the form if required. What I want to do is this:- When the user inserts the CD into the PC, the form will load.When the form loads, I want to search the users PC to determine if Acrobat Reader is installed.If the Acrobat Reader program is not found on the system, then display a MessageBox to inform the user to install the reader from the CD.Would this involve searching the users registry? I would need to insert in my Form1_Load sectionTarget systems would be Windows XP/ Vista with programs on the C: drive as default.

I'm having a problem with closing Acrobat. I'm using vb.net to sign a PDF file in running Acrobat. After I'm done I close Acrobat and try to delete the currently signed PDF file, but I get an error message telling me that file is being used by another process. I tried closing and setting to Nothing AcroApp, AcroAVDoc, AcroPDDoc JSO, but still that doesn't work. I tried releasing them with Marshal.ReleaseComObject(...) still no effect.[code]

I'm currently having an issue with VB.Net and Adobe Acrobat. The issue comes from exiting Acrobat but the Windows Taskbar still states that there is an Acrobat.exe process open. I have tried using Marshal.ReleaseComObject(), but it still hangs there. I do not want to have to rely on the "End Process" option on the Task bar in order to remove it.
Below is a snippet of the code that I am try to using:
Try
'Tries To Close Acrobat Application
acrobatApp.Exit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(javaScriptObj)
[Code] .....
Although I am not sure if this could be a problem - I run a javascript saveAs script on the Acrobat side in order to make a copy of the file. This also could be a reason why it is hanging, but I ruled it out based on basic knowledge of saving files and exiting from other Acrobat/Microsoft Programs. Acrobat only closes when my application ends. (Currently) I am trying to make it consider the case if a user manually closes the Acrobat application.

How would you programmically check if Microsoft word and at least a pdf reader is installed on a machine?
I need to figure out some way if the machine can read a particular file. If it can read a pdf or word file.

so my application (Visual Basic 2010) is making use of Image Magick, via the COM object. If the COM is not installed then my application crashes (not surprising). How can I detect if the COM has been installed, so abort and tell the user to install it?

I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.

I'm working on a project that requires that I programmatically examine the ServiceAccount of all services installed on a machine (regardless of status) to determine Logon Type which will be used as an indicator of which passwords need to be changed on a machine for maintaining security.
If possible I would like to keep the entire project in VB.Net and Ive been looking through the API to find namespaces that contain classes to allow me to do this. Ive come across System.ServiceProcess which does allow me to get quite a bit of information about services installed, but I cant seem to find a way to get the Logon Type (I would guess that it would be returned as a System.ServiceProcess.ServiceAccount object).Ive also tried System.Management using ManagementObjectSearcher and ManagementObject, but Im not sure if theres a way to get that information with a WQL statement (I know next to nothing about WQL, unfortunately).

With the following code I can list the display name of all software installed on a local machine.
'Declare the string to hold the list:
Dim Software As String = Nothing
'The registry key:
Dim SoftwareKey As String = "SOFTWAREMicrosoftWindowsCurrentVersionUninstall"
Using rk As RegistryKey = Registry.LocalMachine.OpenSubKey(SoftwareKey)
'Let's go through the registry keys and get the info we need:
For Each skName As String In rk.GetSubKeyNames()
Using sk As RegistryKey = rk.OpenSubKey(skName)
[Code] .....
What I need is to get the FileName
to be used to start the application like notepad.exe and not just the displayname
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = filename & ".exe"

I have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?

I have a few programs published via ClickOnce. These are highly specialized programs, and are only used by a relative handful of people, but the set of users is likely to change, and is spread over a fairly wide geographical area. The major advantage of ClickOnce....ok, for me, the ONLY advantage of ClickOnce, is that I can create updates and have them (mostly) installed when the end user runs the program. Over the brief time that I have used it, I have encountered these aggravations regarding ClickOnce:
1) The application can only be installed on a user by user basis (it can't be installed for all users at once). I understand why this is done for a general solution like ClickOnce, but it is certainly an aggravation.
2) Updates don't always appear to happen. Usually, the updates do happen when a person starts the program, but a fair number of times, the update isn't noticed, or recognized, or something. This causes the user to continue with the old version, which makes them think that I didn't fix the bug they had, which causes them to give me a raft of excrement, which results in me flipping them the bird. Much hilarity ensues (fortunately, I'm friendly with my entire user group, so this is a fairly accurate acconting of the sequence of events, except that I just laugh at them rather than replying in sign language).
3) Certificates expire in a year. Certificates are a great thing...for some situations. In my case, an alternative seems like it might be better.
4) Some settings in the manifest are so doggone hard to fix that I've nearly given up. I changed the URL that ClickOnce was supposed to go to for updates, and found it impossible to change the program to find the new location. It had to be there somewhere, and I found several candidates, but never could find the critical one.
Because of these issues, I have been tempted to write my own replacement. There are a few issues that I'd like some commentary on. For one thing, security is an issue that is hard to pin down. None of the data I am dealing with is worth a second thought. No cracking of that data would harm anybody or any thing. However, my first thought would be to have people install an app that would go to a web service to check for the existence of an updated version. If one was available, then the existing program files would be overwritten by the new files. If one was not available, then no overwrites would take place. Lastly, if the service couldn't connect, then no overwrites would take place (of course). If the files were compressed for transport, it would be kind of difficult to intercept and inject a different program into the transport stream, so the only weakness that I can see would be if somebody hacked the server that held the new version, and replaced it with something else. What am I missing here?Also, has anybody done anything like this, and if so, what else am I overlooking?

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I think this has to do with a third party OCX control. Below is the output when the application starts. When I install my application on a stand-alone PC or most PCs in a networked environment it runs fine. When I go to some offices that have very tightly controlled networks I have problems.
The set up won't run under the user name so someone from IT must log in as administrator. They run the set up and the application installs and runs fine. The IT person logs off and the user tries to run it and the application won't even start. An error box appears and below is the report. SCANNERLib.DLL is the third party control. Maybe there is something I'm missing when I compile. Maybe the DLL registering funny under the Admin rights. [Code]

I am currently using the FileOpen method wrapped in a try/catch block to determine if a particular Excel file is currently in use or not.
When my app tries to access the file, I would like to be able to notify the user who it is that already has the file open. If I try to open the file in excel while it is in use, the message that Excel provides includes the network login of the user that has the file open. Is it possible to get this information via code so that I can tell the user of my app the login of whomever already has the file open?
