I'm trying to retrieve data from an Access database - a simple one. (Just a single table with one column) My task is to view these records through a 'ListView'. No need to manipulate or anything. Just to retrieve data with a simple SQL statement and display via a ListView.
View 4 RepliesA 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...

I have VS 2005 installed in my sytem fyi.We have two databases, say source database and destination database. The databases is in Oracle. Now we need to pull data from Source database, manipulate it and push it into the destination database on daily basis.We are planning to use VB .Net for this and would like to know if this is feasible. Using windows forms through VB .NET, is it possible to create a exe and schedule the exe on nightly basis to pull the data from source to destination.how to do this as for manipulation of data, there is no intermediate database for us?

Basically I want to know how to access a particular website from my application. I have used System.Net Namespace to request HTML from a website, It returns a complete HTML code which is used by Browsers to render the content on the screen but what i want is to interact with the website only without the use of a browser. I currently dont know how to do that.
I have a application which displays a Image when a user enters a keyword, lets say user enters a word "Envelope", the application will go to Google Images and search for this keyword. Now google returns images as results, the application now needs to download the first result ( which is a image) and display it on a form ). Everything here is done without a browser but via my application.

View 4 RepliesI'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")
so i need to link the database but i want to use the bind source way, i dont like using the oeldbadaptionand all it needs to do is perform a search for records, insert new record and save the record but

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 have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

Desktop computer - Vista 64 bit
Portable Computer - Vista 32 bit
vb.net 2010 express on both of them
I can not establish a connection to an Access db (either .mdb OR .accdb) on the 64 bit computer. When I try I keep getting a message that says "Format at the initialization string does not conform to specification starting at index 0." (this was typed not copied). (There are screen shots over on Connect).
I can establish a connection to a "Microsoft SQL Server Compact Edition" (.sdf) database on the 64 bit computer.I can estabish a connection to all 3 types on the 32 bit computer (.sdf, .mdb, .accdb).The 'funny' thing is that if I establish the connection on the 32 bit and copy the program directory over to the 64 bit, the prorgam loads and seems to run fine. But the %$# _(%* Wizard will not run on the 64 bit machine. Runs fine on the 32 bit but not on the 64 bit. Of course I make sure that the db's are in the location where the program expects them to be when I run the program on the 64 bit machine.
One final thing, when I am in the progam created on the 32 bit and running on the 64 bit and I try Data->Add New Data Source->Database->Dataset only two of the three connections show up while all 3 show up on the 32 bit machine. Also the connection string is incorrect for the non-sdf connection. It should include
