I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.
View 10 RepliesI'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset

I have a multi-project .NET 3.5 solution. It's ASP.NET based with c# code-behind in all projects except one.I'm attempting to access members from a C# project called "Core" from a VB.NET project. I set a dependency to the Core solution in my solution properties. However, Core. brings up nothing. Furthermore, my other C# projects that have Core-Project as a dependency (in the solution settings), are able to declare Core objects. Example: Private Core.ObjectName InstanceName; Also, Intellisense brings up plenty of info in the C# projects.how I can hook into these members from my VB project?
View 1 RepliesFriends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I have my project all set up but I can't seem to fiqure how to put the Access Datbase on it. I am running Windows 7 OS and I am working with VB 2008. I select SERVER EXPLORER and connect to a Data base and choose Access Database file. I click browse and I can find anything.
View 10 RepliesMy vb2008 project is connected ["PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:MyProductMyInvest.mdb"]to an access database. The numerous searches and filters are sql select coded. The database has been added using the Data Source Configuration Wizard. My problem is when published and loaded on another machine it fails due to being unable to locate the database. I have tried the configuration alternative of making a copy and not.
View 11 RepliesI have a single form in VB with an Access database. The form is used to browse the database and works perfectly, however when I compile it into a a single exe file, the database still has to be separate file in the same directory.
Is there a way I can include or embed the Access database as "part" of the exe file so that I have a single exe instead of having an exe AND a separate database file?
I am taking Computing at A Level and need to create a solution for a business.I have thought of my solution which is a log of all the cars that go out on test drive for my dads motor company, i have created a database in Microsoft Access and have saved it as the usual mdb file. i have then imported this into the project and would like to use it.I have created a login form which i would like to use along side the database in the sense i would like it to check when a user enters their name and password for those two things in the database and respond accordingly. I also have created forms in which employees would enter information and then click the submit button, i need this to then place the information into a database as records under the right headings.I have tried using the program and play about a bit but i just can't understand it easily, even when i search for help i have trouble understanding what it all means.If someone could help me that would be great cheersLongy1259

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I would like to access to a SQL Server Database from my Visual Studio project.
I have SQL Server 2005 Express Edition installed on my PC and I have a database with some tables.
In Visual Studio, I open the Database Explorer and I try to create a database connection.
The Add connection dialog box proposes to enter a database *file name* but I cannot select a database *server* and a database *name*.
Perhaps, is it a restriction because it is a free version ?
Within Visual Web Developer 2008 Express Edition, I can select a database *server* and a database *name* !
After trawling around the net for a good few days, i decided to post something here.
Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.
i am trying to connect to a password-protected MS Access 2007 database. I don't have any problems connecting to the database when the database is stored on the C drive, the following command works for me:
View 2 RepliesI am running VS2008 and am using VB2008. I have created a solution file with a Windows Form Project. It contains one form. I created a class project called DataAccess. I selected that project and created a data source. Now I see the XSD for that data. If display the "Data Sources" window I see the datasource. So far so good. If I select the Windows Form project, and then display the "Data Sources" window I get an empty window with a "Add New Data Source" button/link. How do I make the data sources created in the second project available to the first one?
I have been watching the videos for creating n-tier apps that suggest adding a third project to the solution called DataEntities. I did that. I then click on the XSD in my DataAccess project. Then in the properties of the XSD I change the "DataSet Project" property to point to my new DataEntities project. When I save the DataAccess project the DataEntities project gets a file added to it as expected. But then the Data Sources window is empty no matter which of the three projects I select.
Clearly I am doing something wrong. The videos all show the ability to see the data source in the "Data Sources" window after setting up this three project structure. One other thing I noted. In most of the pictures in articles showing the Data Sources window. The top most entity in the window is the project file itself. Then in a tree structure you would see the various data sources under that top most entity. When I was able to see something in the data sources window, the top most entity was a data source NOT the project file, with the data sources under it.
Any idea what I am doing wrong? It seems like I need to do SOMETHING to make the data sources in one project visible to the others. And possibly something to make a datasource visible once split apart using the "Dataset Project" property.

A program that I'm designing for a local jewelry shop to print receipts and what not, there are multiple cashiers. I have written a database in Access with the Cashier ID, First Name, Last Name, PasswordI have added this to my dataset, it shows up as CashierDataSet1. What I need to do is verify the Cashier ID, and the Password match TextBox1, and 2. All the tutorials I have found are for accessing that database on the local hard drive, which would be fine if I could get rid of my UnauthorizedAccessException error. Any ideas or well known tutorials for using a database in a dataset without pulling the text boxes onto the form and creating that navigator ?

View 5 RepliesI made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.
View 5 RepliesIf I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.
