Manipulate MS Access 2000 Databases Via The DAO 3.6 Library On Win XP
Dec 15, 2010
I have been using VB6 to manipulate MS Access 2000 databases via the DAO 3.6 library on Win XP. I have recently acquired Visual Basic Express 2010 and I have not been able to port my VB6 code. I can not find any sample code to use MS Access 2000 from VBE 2010. Is it possible to access MS Access 2000 from VBE 2010?
Here is my VB6 code:
Sub Main()
Dim dbJobCPD As Database
Dim rsJob As Recordset
I am using the code shown below to compare two Access databases with two fields each and write the results to a third Access database. I am getting an error at the "Do While DMReader02.Read = True" line: "Invalid attempt to call Read when reader is closed." Why would the reader be closed at this point if I am using different DataReaders in the two loops?
I have looked around google and downloaded several program with no luck. I have a Microsoft Access 2000 DB which my web app connects to and now published the website with a MS SQL Server DB 5.0. I need to create the tables on it but its not deeming easy. The closest thing I got the creating SQLfor creating the tables was:
I'm currently using system.data.oledb but I can't seem to make the update , search, & delete work fine. Are there any other ways on how to manipulate an ms access database in vb.net easier than my method? Here is my code for searching:
I have a folder C:databases and in that folder there are subfolders C:DatabasesDatabase1 and CDDatabasesDatabase2 What I want to do is have a VB script or code that will go through each directory and make a copy of all .mdb database files found within the folder or subfolders of C:Databases.
I am working on upgrading an old Access 2000 database to VB .NET (2010). There is one form that I am having trouble figuring out how to build so that it works similarly to the Access form. In Access, there is a header, detail and footer for this form. The objects in the detail section only need to be created once and Access will "copy" them for each record in the database and fill in the appropriate information (the form objects include buttons, textboxes, comboboxes, etc.).
How can I do this in VB .NET? Each different area that is chosen will have a different number of sections. I've thought about using a GroupBox, but I'm not sure how to make that work.
I have a mdb file hosted on my site [URL]. I am developing an application which will be running on multiple machines and will contact the mdb file via internet. I am not sure how do i go about it as building the connection string for an online connection.
vb.net 2008, using DataGrid, How to connect with MS Access DataBase 2000?, In VB6 just drag Datagrid and ADODC set the datasource can see the data in few seconds.
How can I connect my vb2008 windows app to an Access 2000 database which is located at www.mysiteserver.com/files/rubbishdatabse.mdb?What code is needed to do so? And where should I put the code in(of coz in the vb app, i know XD, but which part)?
I will start off here by asking the question. How do I make the data from a database be bound to my project? I keep trying to add a new data source so that I can drag and drop things to my form, but I am unable to. I follow the steps, choosing an OLE DB, the file's location (D:Data Connected Applicationsfile name) The conecting string looks like: Provider=Microsoft.ACE.OLEDB.12.0;Data Source="D:Data Connected ApplicationsItem_Database_A.accdb". I choose the objects that I want (In this case, the entire tables option) and then it returns a message to me stating that: An error occurred while creating the new data source: Could not get information for 'WindowsApplication1.Item_Database_A.accdbDataSet3'
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.
Yes, you read it right! Exchange Server 2000. I want to create a script that retrieve information(ie. Last Access Time) of all the files that are place within the public folder of the Exchange Server 2000.
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.
I'm trying to get going with using MS-Access databases in vb.net. In my case, I have a list of MS-Access database paths as strings that I want to talk to. I don't want to add the databases permanently to my project, since there are many of them (hundreds, actually). To start off, I have something like this:
Public Sub main() Dim conn As New OleDbConnection conn.ConnectionString = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _
[code]....
If I run this, it fails at " Dim rdr = cmd.ExecuteReader", with the error:
"Record(s) cannot be read; no read permission on 'MSysObjects'."
however, I can open the same database using the MS-Access client and run the same query without a problem.
I've been using MS Access for the database in many of my programs (they're always local databases, copied to the user's computer) and as is no surprise to anyone here, it's a horrible choice but it's what I knew and so I've just defaulted to it.What is the best one to use? How do I go about buying/getting it? Does it allow royalty-free copies? Can I import my existing Access databases into this? How do I deploy it?
If I import an access database into vb.net windows application will the included queries also be imported and will they continue to function correctly ?
created a database and I am able to read from the database into VB and also able to create a new set of feilds. I do needte a set of records, can't seem to find the right code.The access database has 4 columns one of which is a unique code (column name is 'code') that relates to each different item so I would have the user put in the code to the textbox and then the programme will delete the set of records corresponding to that code
How do you manipulate a string that you have selected from a Combo Box that has been upated dynamically from an MS Access Database table?I have strings that are "1, Surname, Forename" and need to get both the number, and the surname out to put back into a different database table.
I use Microsoft Access databases for my big project but I find the performance is very hit and miss. I time the processes and sometimes there is some serious lag. Here is an example of the code I use:[code]I was told that this is a very old method of accessing databases, which doesn't surprise me since it's the same basic code I was using back in VB6 about 8 years ago.
I see, to my supprise, when I tried to installed the Access Database Engine drivers that you cannot run both 32 bit and 64 on the same machine (I have Office 64 bit installed). If SQL can do it? So I have this nice new 64 bit machine with 64 bit office and my hands are tied... Can't correct code in 64 bit mode, can't read Access databases in 32 bit mode. I just have a hard time with 64 bit being out since XP, that this it just not fixed yet. Humm the Behemoth that is now Microsoft. Want to use OLEDB?
I am using Visual Basic Express 2008 64bit on a Windows 7 64 bit computer. It is running Microsoft Office 2010 University Edition, which only comes in 32 bit so far as I know. I am able to connect to my access .accdb database from within Visual Basic, which I wasn't able to do until I came across this: [Code]...
Beforehand, I had recieved a "Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine." error, and after applying the above fix worked fine. However, now that I am trying to publish my program, I am returned with the same error, no matter what target CPU I select. The program works fine on 32bit machines, however on my 64bit laptop it is unable to connect to the database. I have tried compatibility mode, downloaded many different add-ons from the Microsoft download page, but to no prevail. My understanding is that it is not actually compiling the published version to x86, simply running it as such when I build it in Visual Basic, and because there is no apparent way to set target CPU for compiling,
I need to make an application that from a master database creates a number of access database files (tables of a larger db), then these are manually given to users who fill in data, the database files are emailed back to a user who, through the application, combines them again.The only part of this that I am unsure about is problematically creating the access db's. I have read that through Microsoft Jet OLE DB Provider and Microsoft ADO Ext I can create them (the tables and data), but I also need forms.
I'm doing a little project on the side and was wondering if it was possible to enter data from text boxes on a vb form into two different tables in the same database? [code]
I have used two database (1) party (2)partydup.[code]In both tables i have common field ("code"). I tried to retrieve the value of "description" field from partydup table when the "code" field in both the tables are same. I run the below coding but it is showing the error as "No data exists for the row/column". But i have a record which contains the code field value as 123 in both the tables. Still it is showing the error. Please let me know what is the mistake i have done.[code]
simple coding procedure or recommend a resource for switching between two or more open Microsoft Access databases within a VB.net program, while keeping the same indexed place in each database? The purpose is to iterate through the databases conducting comparative analyses of field values, and writing the results of the analysis to the same databases or another database.
