Regrading VB2008 And Mdb Database?
Oct 19, 2009
A while back I have created an application with ms access 2003. But ms access is limited to what it can do. So I have started to redesign the application in vb2008. The application is a registration/reminder/payment system for martial arts school students. I got stuck with 2 questions.
1) I have added mdb file into vb project, but I don't seem to be able to assign mdb fields with form fields. The only way it lest me do it if I go though a wizard, and then my vbform looks like msaccess form, which I don't want it to look like that. I just want it to look like any other normal application, without the db navigation button at the bottom of the form. If someone has a tutorial that I can look/read to find how I would assign db field to form field.
2) My other concern is that I need the vbprogram to be separated from database with having to create odbc connection. The main reason, is that I always need to add/change/fix features. And that is the main issue I am having with my msaccess app, that is while I am working on it, no one can add/look at the student records. What I would like to do, is that I have a vb app, that will look for .mdb file at the certain location, if it is not there, the use would have an option to either browse for it or create a new one.Then I can do all of the modification and send the updated vb app to the person that works with it, without hindering his/her work.

I'm still passed from VB6 to VB2008 and...I found it very changed!I've learned in few days how to use the most used commands, but I've got a big problem in connecting to an Access Database.I saw that we can connect to a database using:
- wizard connection
- manual connection
I think that using the Wizard everything is more cleaned and I can reuse the code in a simple way.So I tried the Wizard Connection, but all the guide and tutorial explain the connections using DataGrid. I don't want to show DataGrid. I've learned how to import data in listboxes (also in auto-complete mode) but I cannot understand how to work on data in the way I prefer.
- I've got a combobox with a list of data
- When I "change" the selection (combobox_SelectedIndexChanged) you have to load related data (from another table) in a ListBox (in which I can add other items without inserting them in the DB)
- Send all the data loaded in this fields (there are also other data) to create a record in the DB (like "Order of Product")

in VB6 I used the following code to access my Access database tables:
Global gdb As Database ' Global instance of the database.
Set rs = gdb.OpenRecordset(".....various SQL statements")
I am confused about how to do the same under VB2008 Express. "Public dbs As DAO.Database" does not work.

I'm currently designing a client application that connects to a SQL Server 2005 database. My app is being used to display data, allows users to run reports and stats on the data. It is being developed using VB2008. Within my VB2008 project, the connection string to the DB is made via SQLEXPRESS.
The road block that I'm running into right now is that it only allows me to connect to a local DB file (.mdf) only. I tried to connect to a different DB file on a server within the same network domain, and it generated the following error:
"The file "U:Data.mdf" is on a network path that is not supported for database files. An attempt to attach an auto-named database for file U:Data.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." (where U: is a mapped network drive).
Below is the actual connection string in my code:
"SERVER=.SQLEXPRESS;AttachDbFilename=U:Data.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
The intention is to have the DB reside on a server, where there is another application that runs as a service to collect the data and then populates this DB. Then my app would just connect to the database, and allows users to run reports based on the data in the DB.
I heard that this is the limitation of SQLEXPRESS: it will not allow connection to a remote database. This is true? If so, is there anyway that I can get around this limitation?
The main reason that I chose SQLEXPRESS in the first place is that because of the licensing issue. The company that I work for do not want to make the users of our software app have to purchase additional license for the full-blown SQL Server Enterprise edition. I also heard that SQL Server Enterprise edition does allow you to connect to a remote DB (.mdf) file.

We would like to create a client-server architecture application that the server can control all client computers connected to it (e.g shutdown) and we would like to put a security login and a desktop lockeron the clients. The process of the system is that when the clients starts, the desktop is locked and ofcourse the user can't access the desktop unless he/she logged-in. And when the scheduled time (e.g 1 hour) is done, the client computers where automatically shutdown like the Time Logger Softwares

I have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.

I have programmed in VB before (vbexpress 2008) and used "formname.show()" to open and show new forms that I wished to open. I try the exact same code in vb10express(beta) and get errors! Did the code change? I cannot find any information on it if it did... or is it possibly a "betatest error" that needs to be addressed?
