Using VB2005, Access 2003
I'm having a problem trying to read an access table with the following code:
HTML Code:
Dim strConn As String
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
" Data Source=C:DBFILESService.mdb;" & _
[Code]....
I am using the following from the MS website to add a row to an access table and retreive the last autogenerated number.
Code:
Dim cnJetDB As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=test.mdb")
[code].....
This may seem like a simple problem, but I am completely baffled. I am working on a timekeeping application using Visual Basic 2008 Express and Access 2000.
There are three tables being updated by three separate sub routines. Two work fine, one does not.
In trying to resolve the issue I test one field at a time. The test Access query and the code only reference the one field to change and two ID fields. The program runs but the field is not updated. The table has 42 fields to be updated when I get it working.
The Access query is:
--------------------
UPDATE tPPSummary SET W1MonHours = [@W1MonHours]
WHERE EmployeeID=[@EmployeeID] AND PPID=[@PPID];
[Code]....
When I pause the running program at the intRowsAffected it shows 1 record which is correct.
I am really out of options as tho where to go from here. There are no simple spelling errors in the parameters, there are no error messages and the sub runs to the end.
This is probably a simple process but I can't seem to accomplish it for the life of me. What I'm trying to do is transfer user inputted data from a Visual Basic text box into an Access database. The database consists of only one table with three fields: First Name, Last Name, and ID Number (auto-increment primary key). The VB code I have so far is this:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code].....
There are two combo boxes taking user's inputs to return a record in an Access Database satisfying the requirements. This procedure is controlled by a button. However, when it reads "da.Fill(dt, "NETP_ParaList")". It reports error saying that "ArgumentException was unhandled; Object is not an ADODB.RecordSet or an ADODB.Record. Parameter name: adodb" I have no idea what this talking about.
[Code]...
I'm trying to remember how to insert data in to a table. Here is my code
Code:
I get the error
Quote:
Number of query values and destination fields are not the same.
I also get some error about the Insert INTO part not being right somewhere. Am I doing this how you would do it, or how would you do something like this?
I have a table in Access called 'tblRealTime' with a few rows of data and I want to display it in a DataGridView object on my form. When I run the program I get no errors but nothing shows up in the datagrid. My code is below:
[
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ConnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|K0201227Project.accdb;Persist Security Info=False;"
SQLStr = "SELECT * FROM tblRealTime"
[code]....
I have a table I made in MS Access and I want to import/display that table into a DataGridView.I am VERY amateur but I am able to pick apart some code and see what is happening.The thing I know I need is a connection between the two programs but again, have no idea about how to pull it off.I have the free version of VB(2008 Express Edition)
View 1 RepliesI'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.
Code:
Public Sub LoadCareer()
Public rs As New ADO

I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?

Destination: Access Database Table
I should mention that the DataTable contains data resulted by an SQL SELECT query and it's not related to the "targeted" Access Database Table.
I have code that connects to queries in an access database.
[code...]
Is the data not filling in because of the schema information not being retirieved? If so, is there a way around that?
how can i import text from text file to access so that:
Text sample:
F2009021908362600111154050110230000203024116461000000000001000
Would be in access
Col1|Col2|Col3|Col4|Col5 and so on.
F|2009|02|19|08
So the point is, how can i put vb to read from left as many characters i want and put the selected range in to access?
I want to do something like this:
Code:
'create a dataset and a table
Dim ds As New DataSet

Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.
I want to add a new table in my accdb and copy the content tfrom an existing table into the new one.
Is there an easy way to do this?
database = microsoft access application = microsoft visual studio .net 2003
i have a dataset, i dont know how to hide the rows.
I have a database called Houses.mdf , in it is a table called House with ID , NAME , PRICE.
I want to SUM all the PRICES and get a total price of all houses. I also want to display the result in a textbox.
I am confused as to why you have to pass the name of the table in the .Fill() method? As an example, see the following code:[code]I have already specified "NameTable" in the query string, so why do I have to put "NameTable" again in the Fill() command?

Would I be able to for example, write the contents of Textbox1 (say it's labeled First Name) and Textbox2 (Last Name) and make it write to a database. The on the next screen, form, window, whatever....have it say Hello (First and Last name that was put in on the previous screen).
View 2 RepliesAnyone know how to copy a table from one database to another? I know the statement 'INSERT INTO Table1 SELECT * FROM Table2' but I want to copy from one database to another from a server to a PC. Of course, I could do a select statement for all the records and use a loop to insert them one by one, but surely there is an easier way.

Is it possible to have a quick and easy way of retrieving the last 10 records from a table?
Currently what I have been doing is retrieving all the records then one-by-one cylcing through each record until I have the last 10. To me this seems to have a lot of over-head reading each record. I just wondered if there was a quicker way of doing it.
I have created a database in VB2008.NET using SQL 2008.
My problem is that while I am in the form where I see the the data, I want to retrieve backwards the related data from Owner and Car eg. the owners name and the car model.
Is there any way to do this in a single row?
I am trying to update one table with results from another table as such:
Table A (field, type) : Table B
ID (key) Integer : ID (key) Integer
ParentID Integer : IssueID Integer
Number String : ParentID Integer
: Number String
I need to construct and UPDATE statement that does:
Sets B.IssueID = A.ID When B.ParentID = A.ParentID AND B.Number = A.Number AND B.IssueID = 0
Here is what I have so far but it is producing an SQL syntax error (missing operator)
sqlStr = "UPDATE B SET IssueID = A.id FROM B JOIN A ON (B.ParentID = A.ParentID AND B.Number = A.Number) WHERE B.IssueID = 0
I have also tried
sqlStr = "UPDATE B SET IssueID = A.id FROM B, A WHERE (B.ParentID = A.ParentID AND B.Number = A.Number AND B.IssueID = 0)
