I am using Visual Basic 2008 express and I have created a simple database application for my y6 pupils. The program will eventually be installed on the school system but, i want to know how I can ask vb to find which folder the application was installed in and get it to return a string.

I have to make a visual basic program for a school assignment. I am an absolute beginner at it though, but am willing to learn.I have to make an income calculator for farmers that make giant turnips.
So basically:
1. If the turnip weighs less than 350kg, the farmer will receive $2 per kilo
2. If the turnip weighs 390 or more, the farmer gets $1.50 per kilo MINUS $180 for a maintenance fee.
3. If the turnip weighs between 350 and 389kg, it has to be sent to a paddock that costs $25 per week for lease. Turnips loose 1% of their mass per week in this paddock. When the turnip gets below 350kg it can be exported. As ships depart weekly, turnips may drop a bit below 350Kg before departure.
Create a profit calculator for the turnip farmer for a list of cattle weights.
Functional Requirements: oEnter the weight of each cow into an array oCalculate the income from each cow and store in another array oAdd up the values in the array and display total income.

I need to make a program for school that closes the active window. My application does now SendKeys.Send("%{F4}"). It works but, it also does it when there are no active windows. I want it to close only the active windows.
View 6 RepliesWe are creating a VB program for school to collect data on student attendance and populate it to a table. I have all of the 'GET' statements but am having trouble creating the 'Insert' procedure. This is what I have so far. The form being used to fill the table has 4 items being recorded. 'Present' radio button marked as present, tardy or absent; StudentId, PeriodId and date. Not sure if we are on the right track. The target table is tmAttendance. There are approximately 25 rows of data on the input form.

Also, if there is another way to verify that a dll is installed, without having to supply a full path, please let me know.
I have to access the active x dll which is installed on my system from VB.net.
I added as reference and followed all the steps as given in I have declared private mycomponent as activexcomponent.libclass and i gave constructor for this i.e. creating the object for this class in the constructor of the main form as mycomponet = new activexcomponent.libclass()
Then the following expection is coming when i tried to run the program.
System.InvalidOperationException: An

View 6 RepliesI am writing a application where i need to know which games are installed on a system.I have 3 ways by which i think i can detect the games
1: Scan specific parts of registry and look for key names that match with a List of Publishers. The list is manually maintained.
2: Scan the hard disk for and do same as in step 1
3: run the program in background and check for programs in memory that use a large portion of memory(which games always do) and if they use Direct X ( Which all games do except for some) then its a game.
Now i have been thinking about it and first and second method seems to be in need of a updated database ie list of publishers to make out if a particular program is game.
I am having trouble developing an asp.net page. I can create custom collections and use them in win apps, but when i reference the system.collections namespace, the page response hangs up. No exception info is passed back or anything. The page just freezes. Is this a common problem. I am wondering if its due to the assembly not being present (but am unsure why an exception wouldn't indicate this.).

View 1 RepliesI am trying to create a plugin system. I have the actual plugins working fine but now I want to implement a system that knows whether the plugin is installed or not. I can get the plugin name when the form is loaded (ex. "Plugin1"). I then want to check this against something to see if that specific plugin is already there (if not add it) and if it is there is it enabled. I was thinking of doing this with an xml file but thought that might be a lot of work reading and writing each value. I then thought of the My.Settings and was wondering if this is possible. I would want to create an "element" for the name and give it a value of either true or false.

View 1 RepliesQuestion: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
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'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?
