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?

where I should declare my variable when using forms and the scope in my test code.
In my code below I have declared variable x in my form1 which can be printed in form2.
But when I create a structure in form1, initialize an array of the type protorec and try to assign values to cards(1).firstname etc... I get a "declartion expected" error.
Why does it work for x but not for cards(x) my array of records?

I programmed in VB6 but with VB2008 I have trouble with this:I have a table called Clientes (Clients). One of the fields is called Provincia (State), but this is a numeric field wich references to a Provincias table.So, when I show the Clientes from, the Provincias field must use a combobox with the province name instead of a textbox with a number.

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")

View 8 RepliesI'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.

I am looking for some help in finding the best way to display a progress window for a module I am working on.I have a VB2008 app using an Access 2007 db. One of the MODULES in the Access db does a masterfile update and I want to show the user what is happening in process.
The VB2008 app calls the Access module to do all the work which is FAR FASTER than having VB2008 do all the work.The goal is to have a small window popup and display the progress. Once the process is done, close the window. How would you do this? Use a Access form? That works but it not clean looking at all. Is there something else that might work better?
Something like a msgbox that opens and can be updated while the process runs. Once the process is done, it can be closed. The user will not need to interact with this window - it's just to show the applications progress.
A simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...

[Code]...
I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
