VS 2010 Access Database In .Net Setup That Is Writeable In Windows 7?
Jul 15, 2011
I have a VB.Net program which reads and writes to an Access database. I am trying to deploy the program using a setup (created with INNO Setup). Upon installation on a Windows 7 computer, Windows 7 is preventing it from writing data without changing the permission settings. It reads data but it doesn't write data. This problem doesn't happen in Windows XP. My question is: is there any way to make the Visual Basic .Net program write data to an Access database on Windows 7 from the setup without the user having to change permission settings?

In an ideal world, we wouldn't need to educate our users about the "intricacies" of ZIP files One of my apps is a stand-alone-ish app that has no dependencies that need to be installed. Well, except for the Framework of course.So, in order to make the download smaller, I've zipped up the package. One of the functions of the app is to download some files into a subdirectory the application is located within. Well, some users don't unzip the package and as we all know, you can't just download some files into a ZIP file. I spent a good 20 minutes looking through my code and adjusting things to figure out why it wasn't working for one user, when I realized there were no issues in my code and that he probably wasn't unzipping the package.So, does anyone know of a method to determine if the directory my app is in, can be written to?I know I can just try writing a small file or something and catch the exception, but that seems... sloppy.

I'm working on a simple data logging program, and I have little to no database experience. I wrote a little VB forms app to log the data to ms access and then graph the data, but I'm having trouble with adding records to the database. First, I created a simple one table database in access. Then, I added the database to the project as a data source, and gave it a data set using the wizard. Right now my code looks like this:

There are no problems during build or run time, but I do not see changes to database after the program runs.

I am writing a program that is using a access DB for the info to be displayed. However when i started making the program i started by just databinding the listboxes.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'AcskillsDataSet.Skills' table. You

but now that im looking at the data this is prolly only useful for simple data. Im wanting to seperate the data from queries into multiple boxes. Am i better off just manually having a connection to the database and running queries into arrays to sort the data?? The above method looks like im going to be trying to fight the databound stuff. There are two tables and the way the built in query builder is im starting to think its easier to write my own queries in variables or whatever.

I have created a setup using INNO which puts a Visual Basic 2010 Express program on the computer to update an Access database. It works on my Windows XP computer. On the user's computer, which is a Windows 7 computer, the Access database comes up as Read Only when opened. I get an "Operation must use an updateable query" error in the Visual Basic program when I try to create a record. The database has Read Only checked off in it's properties. But when you open it in Access 2010, it says Read Only at the top. (This computer has Access 2010. The database itself is in 2002-2003 format.) How can I get this database to be updateable on the user's computer? It works on my computer/does not say Read Only when opened in Access 2007.

I'm trying to add a string to a access database, for a column that was originally designed for numbers, i have changed the data type under the design view from number to text, yet I still get a error saying that it cannot convert the string expected int32
Input string was not in a correct format.Couldn't store in Parent_ID Column. Expected type is Int32.This is the full exception, i would have put it into code display but the option wasn't there
System.ArgumentException was unhandled
Message=Input string was not in a correct format.Couldn't store <A-238> in Parent_ID Column. Expected type is Int32.

I have written many programs and never really needed a database before. Just never came up. I am a self learned programmer. I have experience in using php and database on websites etc. I am currently writing a program in VB 2010 and need some assistance in using a database.simplest way to setup and use a database in VB. I would believe that it's better then saving "clients/data" to a file. . The software is being created only to be used on one computer and not over a network etc.

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

I have a VB.Net windows application which needs to modify a MS Access database availabe in server. The login user does not have permission to the folder where the database is available. So I am using windows impersonation with another user's credentials to access to that folder.This works fine and I am able to create a new text file in that folder. But when I try to access the database try to get a dataset from the database, it gives "unspecified error". When I check in the internet some people say that there could be problem with temporary files that OleDB tries to create.

My windows application was written in vb.net and i recently added a web service to it so that I could place the access database in it and connect to it via the web server.

The problem has been simplified for the purpose of clarity. I want to make a windows form application that uses an access database. The application will store the list of person's basic details such as name, age and country. The database contains two related tables ie person(id, name, age, country_id) and country(id, country_name) My windows form contains TextBox, DateTimePicker, ComboBox for Name, Age and Country respectively. Now I want to make CRUD operation Programmatically (Not using Visual tools) in the same form with some navigation buttons.

I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?

it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!

I'm having problem with our germany customers whose operating system uses dot as thousand separator and comma as decimal point.I have an application which reads some text from an Access database, parse it into data and display on a datagridview,the program also needs to write the data into another file as input to another application. right now, it seems when my application parses doubles (say 0.2500),germany os will always return everything except the decimal dot(so 0.2500 becomes 2500),and that just messed up the whole process...so my question is, how can we detect the locale of the windows and parse the doubles correctly?

I've built my program a database in Access 2010. Works very nice. But I've had a thought. When my program is compiled and I give it out to users. Will those users need a copy of Microsoft Access to use my program. If so, How could I make it so that no install of Access is needed.

There were several reference to compiling the program using x86.
Go to Project menu -> Properties -> Compile tab -> Select "Advanced Compile Options" -> Select "x86" instead of "AnyCPU"
I followed the path and there was not any option to select x86 in VB 2010 Express.
