Avoid Linked Table Manager Message While Opening The Access DB?
Jun 27, 2012
My Application ( Vb.Net) is to scan Access DB forms and find out the Activx control if present and it works fine. But my problem is.In some DBs we have tables with mapping path to specific locations (Table Property->Linked Table Manager) and when we relocate these DBs then we need to change the path manually otherwise it will show a message to re-link ( Access DB message) while opening the DB. And I am facing same problem while scanning through my Tool as well and my process stops, continue only by manual intervention.
Do I capture the massage event and send some user specific message to user in the Log file or Report and continue scanning further?

I have a foxpro table <b> INVENT.DBF</b> linked in MS ACCESS. When I tried to do a search in the table from vb.net application, it is taking a long time. So I want to index the foxpro table and then use it for search.
Here is the sample code I wrote in vb.net <i>
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT(ITEM_NO) ", cn)
cmd.ExecuteNonQuery()</i>
But I am getting error "Cannot execute data definition statements on linked data sources"
What needs to be done to index a linked foxpro table using VB.NET.

I am writing a small program to update data in a SharePoint list. Now where I cannot develop or use applications for SharePoint unless I am on a SharePoint server, I thought I would cheat the system by using Access to link to SharePoint lists, and then use Visual Basic to play with the Access tables. I need additional functionality other than what VBA can provide me, so that is why I am using the VB layer.Is it possible that this is not permitted? Whenever I try to update an item in the table, I receive the message:
"cannot update '(expression)'; field not updatable"
The word 'expression' here is not a filler I added, this is the actual error.If I try to make the edit manually in the table using Access, it works fine (I haven't tried it through Access VBA yet...).
How my code works is this:I have a Dataset added to the project which connects to the Access database. I add one of the tables to the dataset and create a Class object to reference the table adapter (essentially a Data Access Layer). I can read all of the data fine, and when a change is made in SharePoint, my application sees the updates when it refreshes. But when I try to write back to the table I get the error message above.
For
Each r As
DataRow In TableAdapter.GetData.Select("Name LIKE '*" & FileName &
"*'")
[code]....
There are other columns in the table and some of them have default null values. I only want to update these two fields, but it almost seems like this is not possible. I thought I might be somehow opening the Dataset in a Read Only mode, but I can't seem to find that option anywhere.

First timer here, I love the site!
Running:
- VS 2008
- Sharepoint 3.0
- Access 2007
- Windows Vista (The machine I'm developing it from)
History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...

I created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?

I have a large number of MS Access databases that I'm automating to relink tables. However, there is one table that can't be relinked normally as Access says it has too many indexes. A manual work-around is to link to the view in SQL Server (2000/2008) and rename that table.Now, I want to do this programatically (I'm using DAO to relink the tables, which works nicely). I've been looking at CreateTableDef, but I don't know if this is the right way of going about it. I don't want to hardcode 260+ fields that may change (this is the main table from a 3rd party vendor, so I have no control over the fields in this table, or any normalization for that matter, but that's another topic...).Also, 98% of the tables being changed are Access 2000/2003 tables. The other 2% are Access 2007/2010.[code]

I have an MS access database with some .dbf files linked to it. One of the dbf file is a sales file. I am trying to generate a report for each of the month's sales. For that the sales dbf file will be different for each of the month. I want to give an option to the user to specify the file name from which he wants to use to generate the report. After accepting the input from the user, i need to link to that table in MSACCESS. Is there a way to achieve this from vb.net

Currently I have DataGridView box, clicking generate button fills it with a query from the database.I want the add button to add another row filled using the same query, so far I cannot get it to do it.Current generate button code:
Me.TableAdapter.FillBy1(Me.DataSet.App)
Add button code:
Me.DataSet.App.Rows.Add() - this does add a new empty row
I tried sticking the generate code inside (between add brackets) it but that just did the same thing as the generate code.

I have started a little program which is linked to an access database, and it basically allows the user to input a name and a picture, with the file path stored in a text box and the picturebox getting the picture location from said text box. At the moment I am using the BindingNavigator to go between data. Everything works fine, however, whenever I press previous or next, the picturebox loads up the picture using the file location of the previous datas picture field. How can I tweak this so that when I press next or previous it loads the picture into the picturebox using the file location of the data I am going to, not coming from? [code]

Made what I think was a tactical error by using lots of 3rd party controls that made it easy to get stuff going but resulted in carrying a lot of baggage with my apps. Now it is finally time to switch to VB.Net and I want to avoid 3rd party controls as much as possible.
The database is MS Access. Master table called GroupName, key GroupID, string GroupName. Child table is GroupCustomer, key GroupID+CustomerID. Two datagridviews, GroupName on top, CustomerGroup on bottom. I've studied the one to many videos and howto's and it is easy and works like a champ. Fill the tables, sort, filter, add, update, delete, all is well.
Top grid
GroupID1 GroupName1
GroupID2 GroupName2
and so on.....
[code]....
However, adding a third table is where I get into trouble. In the bottom grid I want to link customerID to the Customer table to pick up Name, address, city, state & zip for display purposes. I've modified the table adapter to create a select query returning the lookup data with the groupID and customerID. It displays nicely on the Fill but doesn't automatically refresh the customer lookup fields when I add or change a customerID and I can't seem to update new records or deletes. The only table in my query that I want to update is the GroupCustomer table but the query is not updateable.I've been trying to figure this out, read articles, learn, step back and think but am still stuck. how to use the controls that come with VS2010.

I have a system that gathers raw data from electronic devices, uses that data to populate a set of tables and allow uses to add/edit certain data and report on it. (Kind of basic right...NOT) There are 3 applications that I've written that use the same database.
One is a client that is on 3-4 user machines which allows them to see the data that has come in and work with it.
Two a Data-to-Information process program which takes the raw data, checks up certain information and puts the results into the database.
Third is a data gathering app that interfaces directly with the electronic devices and about 10 times per day places the raw data into a single table in the database.
If a user is in the 'client' application the data processing application crashes all over the place:
1. Database file already in use.
2. Unrecognised Database format
3. File locked exclusively by User on PC X.
Almost always on a different line of code and once when I made it retry over and over I managed to corrupt the database and had to Compact and Repair it to fix it. If no one is using the client everything works perfectly. On each client machine is a database with linked tables to the server machine. The machine that is running the Data processing is the server and the processing is using a database in a different folder that also has linked tables.
I have gone through all the recordsets in the Data Processing application and made sure that they are only using ForwardOnly and Read Only. They edit the data only with Insert, Update or Delete queries. I'm about to do the same in the Client Application as it seems to be the one that is locking everything all the time. The client machines haven't crashed on that error at all. Does it matter which version of Access is on the client and server machines? (All the clients have Access 2003 and the server has 2007 but the Database was created in 2003). Should I just convert the Access database to SQL server and be done with it?

I am trying to create a smart client (multi table manager). I didn't want to make it a MDI app, so I used a TabControl to host each table UI. I am having problems with the BindingNavigator control. When I drag the table grid from the DataSources to the top tabpage, the designer adds all the needed controls. However, on the other tabpages it doesn't add the BindingNavegator. So, is this the proper behavior or am I doing something I am not supposed to do? What would be the best way on doing this? Do I need to make it a MDI app.?

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.
