Accessing Access Data Tables With VB 2010 Express

Sep 5, 2011

I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

VS 2010 Express Accessing Files?

Jun 1, 2011

My problem is that I have a program which needs to access images for multiple choice questions, hundreds of them. Now when I publish the program it is not taking the images with it. I have read some information by 'kleinma' regarding publishing and he says to right click on the Bin and click include in project, but when I do this there is no command in the menu for this.

I have included all of my image files in the Bin and have also added them using the resource editor, but to no avail As I have indicated it is the Express edition, could this make a difference

Accessing MySQL Database Through 2010 Express

Sep 16, 2011

I am trying to follow this userguide url... to basically build an application that will allow users to connect to my database, from an exe file. I'll try to explain as best i can. The plan is, users will launch an exe file that i have built in Visual Basic(VB) 2010 Express. When they launch the application they will see a 'login screen'.I am following the example guide (see link above), and will customise it once i can connect to the database. For some reason whenever i connect to the database it gives me two errors, the first is if i use the 'debug' mode in VB to test the script (note it doesn't produce any build errors), the second is if i build the application and run it as my users would.

1)Error Connecting to Database:Access denied for user 'mike'@'92.**.**.***' (using password:YES)

2)Error Connecting to Database:Unable to access any of the specified MySQL hosts..The ip address starred out (*) is my local machine ip address.The server is the server in which my Database runs on. 'mike' is a listed user on my 'user' table, the password i use is the password assigned to this user on my table.

3)I've rebuilt the whole VB project, but still no joy, wern't expecting it to as there were no errors generated.

4) I've read, but don't really understand that it could be something to do with my database not being able to be controlled remotely, only locally. I started digging into 'Access Your MySQL Server Remotely Over SSH', didn't really know if i was going completely off the mark, it didn't mention needing to do any of this in the guide i've been following, but just a thought. It might be the case as i've tried to access my database through a programme called MySQL Administrator. I punch in the host,username etc and connect to my database, for some reason it won't allow me to add new users, could this be because i can't control my database remotely? Would this stop what i'm trying to do working?

5) When trying to install the MySQL.Data.dll file i had great difficulty in choosing one and finding it, adding it to my project using the 'Add reference' in VB. Finnally got it how it should be (i think), installed MySQL.Data.dll Ver into my project.

.net - Accessing Tables From Different .mdb Files?

Feb 1, 2010

I need to show a grid of saved projects (compare "orders") in a datagrid, where the projects are saved in an Access 2000 database with a similar schema as follows:

ID Name Country_ID Plant_Type
1 'Test' 1 1
2 'Second' 2 2

Let's call the file "Projects.mdb". This is then showed in the datagrid as:

ID Name Country Plant Type
1 'Test' 'Germany' 'Free Range'
2 'Second' 'France' 'Inclined Roof'

where the countries and "Plant Types" are fetched from a different table in a different .mdb file (also Access 2000, call it "Language.mdb", although there is a lot of different background data in it), depending on the current user's language preference. It is unfortunately not an alternative to merge these .mdb's into one file.

To be able to show the datagrid I have so far linked the tables from "Language.mdb" into "Projects.mdb", but this screws up when the project is being installed on another computer with the .msi file i created (we'd like to have this easily packaged and installed), as the "Language.mdb" doesn't exist on the linked path on the target computer (Basically the problem here).
I can come up with the following solutions:

Force all users to install on the same path, so that the links will work (undesirable)Use connection strings in the query as shown here on MSDN (still trying this out, but I need to work on the details)make a post-install script that relinks the tables according to the correct path.

.Net 2010 Express And Access Database On 64 Bit Vista?

May 22, 2012

I posted this as a bug on MS Connect and am wondering if anybody else can verify the problem: I been beating my head against the wall for about 3 days and I don't think it is my problem.

Desktop computer - Vista 64 bit
Portable Computer - Vista 32 bit 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

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.

VB 2010 Express Opens MS Access Database As Read Only

May 16, 2011

I am brand new to VB. I am using VB 2010 Express. I have a MS Access database and can read & display the data. However, when I enter a line of code to manipulate the data I get a "read only" error message in the project editor. I have checked the file and directory structures from windows and the command prompt. I have even used the "attrib" command to make sure the file was not read only. Then I put the following code in the form and it dispaly the read only message.

Dim infoReader As System.IO.FileInfo
infoReader = My.Computer.FileSystem.GetFileInfo("C:zzz-devaccesswhitneywhitney.accdb")
If infoReader.IsReadOnly = True Then
MsgBox("File is readonly!")
End If

I am using the VB 2010 Express DataSource to connect to the MS Access database and not a connection string in the program.

Accessing Word Tables Created In Word Templates / Accessing Existing Bookmarks In Word Templates?

The query, shown first in the attached code, works well if there is one column in one database table, however it does not work well when there are a number of columns with a different number of fields respectively. The CategoriesID encompasses the entire tables contents.I devised a function to determine the total number of fields within a particular column and then attempted to incorporate this, without success, into the second query, shown in the code.

Will VS 2010 Express Read, Write To Random Access Files

I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?

I'm using Visual Basic/Studio 2010 Express to run my VB program using MS Access database.

Can't Access "Resource Designer Toolbar" In VB 2010 Express

Feb 12, 2012

Created MyLitsBox project as described in Michael Halvorson's book MS VB 2010 Step by Step book.  Tip box on p. 89 says to make programs more robust embed images into application rather than use absolute path names to link images into the application.  Searched on Halvorson's recommendation "How to: Create Embedded Resources" and found the info at: [URL]

OK.  As usual the most difficult thing is finding the menu item, etc., the instructions direct you to.  Do the people who write these instructions ever try using them?  


Instructions are as follows

To edit a resource by using the default editor

With a project selected in Solution Explorer, on the Project menu, click Properties.

Click the Resources tab.

On the Resource Designer toolbar, point to the resource view drop-down, click the arrow, and select the type of resource that you want to edit.

Double-click the resource to open the default editor for that resource type.

In the Properties window, select the Persistence property and change it to Embedded in .resx.

It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error  "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed.

In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).

Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.

run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer.

I tried looking up the net, but most of the topics addressing a similar problems use DAO, and I understand that it is not completely supported in VB .NET. I am fairly new to VB .NET and I am not quite sure how to address the problem or where I am going wrong.
