Detecting If Program Is Installed?
Mar 6, 2012
I currently have a property in my program which returns a true/false depending on if the program is "portable" or not. I need this to know if I should do a certain thing or not.
It checks if it is by checking if the registrykey the installer creates exists, here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\MyProgram
(And under the Wow node if the OS is 64 bit)
The problem is, I am trying to get rid of the need for admin rights, and this is the last function that needs to be fixed. But I don't have a clue on how.
Why I want this property is because then I don't need two separate versions of my program (like a set property in My.Settings which I set before I build).
The only files that differ using the portable vs the installer is one file, but the reason why I don't want to base the result on the existence of that file is because I want to warn the user if it's not there (if the program is not in Portable mode), so he can reinstall the program.
how I can check if the program is installed by an installer, without using admin

I need to be able to detect which version of Excel I have installed in my machine from some .NET code I'm developing. I'm currently using Application.Version for that, but it doesn't give me information about Service Packs.

I have an Access 2007 database that runs constantly, the form on the database basically runs a timer every 10 seconds and runs a Macro. The problem I have is that when the backups run at night the network connection the database is on disconnects for the backup, so the database crashes with the error.
"Your Network Access was interrupted. To continue, close this database, and then open it again."
What I would like to do is create a small VB Application that runs on the machine that the database runs on, detects when the database has a problem, closes down the database process then restarts the database.

I have a program which when a button is clicked on a form sends the form to the back, so that Notepad can open on top, then it opens up notepad
Me.SendToBack()
System.Diagnostics.Process.Start("notepad.exe", myPath & "*********.txt")
Now what I want to do is to detect when the notepad has been closed then I can bring the form back to the front and I just do not know which commands to use for this to detect a program outside of VS 2010.

I am using VB from Visual Studio.net 2008. I need to understand how to build a VBScript or Application that will detect when a flash drive is inserted into a Windows XP SP2 system. Once the drive is detected, the VBScript/App must then automatically search for any available .ppt file (power point) located in the root directory of that flash drive. If the .ppt file is found, pptview.exe will launched opening the file in question.
This script will be located in the startup folder and will run until a flash drive is entered and then it should pause until the flash drive is removed and then start searching again. This is for a kiosk to be used at trade shows for a company I am working with. The company wants this to be simple and automated and only requiring that the user setup the kiosk, which has no keyboard or mouse, plug in a flash drive with a .ppt file on it. The system will then automatically load the slideshow and play until the system is shut down or the flash drive is removed.
I am pursuing this option because an autorun.inf file on the flash drive only adds another line item to the autoplay dialog. Although it may be possible to write a small script that will select that item, there is no guarantee that the user will have that autorun.inf installed on the flash drive in question.
Also it may be better to copy the .ppt file into a temp directory on the kiosk machine, so that in the event that the flash drive needs to be removed there is not data transfer taking place, minimizing the possibility of data corruption.
Most of the file handling I may be able to handle on my own, but it is the detection of the flash drive insertion and removal that is a problem. I am looking for some clarity on this point first. I may ask other questions later, but for now that is the biggest hurdle I have to cross. [URL]..

I need to be able to detect when an external program closes so that I can start another event within VB 2005. I have tried to do this by monitoring the processes on my computer. The problem is that this programs comes up as some weird sub-process. It has an Image Name, which is indented from the other Image Names, and it shows that the User Name is the Administrator. This is the only information you can get from the Processes tab. There is a Task Name under the Applications tab, however. I was wondering if there was some code to monitor the Applications tab instead of the Processes or if there is yet another way to do this.

I'm using VB.Net 2005 Pro and want to be able to check if a particular program is installed. I've seen lots of ideas about checking files in the program files folder or scanning the registry for keywords but none of these seem particularly foolproof. Is there a way to get a definitive answer to if an app is installed?

I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.
Imports System.Runtime.InteropServices
Imports System.Windows.Forms
Module Module1
Sub Main()
Dim t As New MouseHook

i have been searching around trying to figure out how to copy the same idea a few programs have done in the past. However I Can't remember every program that did this but a PC MMO Hunting game Called: The Hunter does this technique.Their entire system is MySQL on a server, and displayed through a website You pick your options on the website and then click "Start" and it opens the installed program from your computer up with the given parameters Quick Example In case i managed to confused you guys.
I have a Program that's just has a text box on it From a website on a server: you can Type in Your username and then click "Start" as an example of a button, which would open up my program explained above with the users name in the text box. i figure there is some type of word for this, but i can't seem to figure it out i looked into web services to see if its what i need, but i couldn't seem to figure out if it was or not.

I want to make a program which first of all check whether a serie of programs is installed, if a program is installed I would like to find the installation path, so I will be able to work with it further..My first though was to check in the registry, there is theinstallation path also mentioned right?Another possible way was to search all the harddrives for a specific .exe fil. If then the file is found, the program is installed, and you should be able to find the path to the found .exe file. This is more "secure", right? - Because not all program is registred in the registry right? (E.g. if you move it from another location, and doesn't install it).

I'm wondering how I would go about creating a program that once installed was a windows toolbar. What I'm trying to do is similar to the clipboard, but I want to customize it to my own style. I work in a data entry job and many of the bills we enter have similar information that I'd like to be able to enter without repeated typing. I'd like the toolbar to be docked to the top of the screen, and have several buttons on it. Clicking a button, while having a focus in my data entry program, would paste the button's text (or the full text of what the button caption represented) into the selected field. Alternately, if focus between multiple applications is too difficult to try, then clicking the button would highlight the text and copy it to the windows clipboard, so I could then click back into my data entry program and hit ctrl-v. I dont need help on the program itself...just on how to make it as a windows toolbar, if possible.

I created a program using visual basic. For some functions the program accesses a dll which was created using visual c++. When the program is run on a computer that does not have visual studio installed, functions which make calls to the dll generate an error: Unable to load DLL 'filename.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1).Reinstalling the application does not help, and when the program is run on a computer that does have visual studio installed, calls to the dll work as expected without generating any type of error.Is there some component that is installed with Visual Studio that I need to attach to my program installation? Is there some way I can create or access the dll such that it does not need this component?

I have a VB project that I created a simple setup project to deploy. It installs fine except for one problem. It crashes because it can't read its own application directory. Included with the program are an xml and schema file that it needs to read when starting.dditionally it may create a log file, also in its application directory. Either of these will return errors under the default install. This was not an issue when running the program in VS and if modify the program to work with another directly like C:Temp. I have a workaround in which I change the permissions of Users group to Full Control for the application directory

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.
