Update Fields In Access Database?

Jan 5, 2011

I have been tasked with writing a program for our yearly reviews. We want all of the information gathered in the form to be submitted to an access database. I have created the form and the database. I can send info to the database but it is put on a new line everytime it is submitted. I would like to check the first column of the table to see if the user login is already there. If it is there I would like to update the information. If it is not there I would like to create a new row. This seems simple, but I can not figure out how to see if the user login is already there.[code]...

Apr 17, 2009

I've been attempting to tinker around with connecting a MS access database to a vb 2008 app. I've successfully connected and can access the data by using the add data sources tab. But what I'm trying to do is create a form that has a (1) single line text box, (1) button, and (1)multi line text box. I enter a name in the single line text box, click the button(search db), and when the info is found, it is displayed in the multi-line text box.

Search Form With Different Fields To Access Database

Jan 21, 2012

I have finished my database using Dreamweaver ASP VBScript and Access, the only thing left is to create the searching system. My search form works fine when posting just one filed. The results page Recordset goes as follows.

Code:

I need 7 different fields on my search form, this what I did but it doesn't work.

Parameters:

Name: MMColParam
Type: Text
Value: Request.Form("Ref")
Default value: 1

Name: MMColParam
Type: Text
Value: Request.Form("New_resale")
Default value: 1

"Price" is a special one because this is a list menu with different amounts, like 50.000, 70.000, 90.000, and so one. The idea is to make this list menu post to the result page, only to display records under or equal to the given value. less or equal > than 50.000 or 70.000, etc.

Updating Fields In An Access Database Using VS2010

Oct 7, 2011

how to update fields in an Access database through VB. What I'm supposed to do subtract the quantity of the daily orders from the inventory quantity. My textbook is a little bit vague at this point, because the only way it describes updating the DB is manually through the BindingSourceNavigator. I don't want to enter it manually, I want it to subtract the quantity from the orders table.

Create Word Form Fields With Memo Fields From Access?

May 27, 2012

I'm trying to create a table in Word using data from a table in Access. There are four fields in the access table that I need. 3 fields are text which I can populate the Word without any issues. However the fourth field is a memo with >255 characters.I'm struggling to come up with the proper code to allow me to populate the Word field with the memo data that has more than 255 characters. The code I have so far is listed below. But when it hits the memo field, it crashes on the line I marked with **. I know it's not text, but I've tried many different field types, but nothing has worked so far.[code]...

Adding A Column To An Access Database?

Jun 29, 2010

My program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.

contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)
contactsCommandBuilder = New OleDb.OleDbCommandBuilder(contactsDataAdapter)
dtContacts.Clear()

Adding A New Record In .NET To Access Database?

I'm at another wall in my project. I've been trying to get it to add a new record to a table but I got a message that said "Object reference not set to an instance of an object" but I have no clue where the error is popping up. I am also unsure of whether the coding for adding a record will actually work on not.Here is the code for the form with the bits subs that I'm sure aren't the problem removed (as they have no relevance to adding a record);

Adding Pictures To An Access Database?

May 25, 2009

I have a program for school that links to a database. They are listings of real estate and in the browse of the database I have pictures that can be scrolled through as well. The pictures are added to my access database as OLE objects and then just linked to a picturebox to be displayed. However, I'm wanting to add another functionality and allows the user to upload a picture that can be added to the record as well. But I think I'm having a conversion problem.This is what I have right now that is working...but I would like to be able to change that nothing into something.

Public Sub AddToDatabase()
CheckType() 'Convert radio button selection to string
'Sends table adapter items to add.
'Input Order: SELLER, AGENT, PRICE, DATE AVAILABLE,

[code].....

Experimenting, I've tried just addressing pictures from my.resources but the errors I get are... "Type System.Drawing.Bitmap cannot be converted into1 dimensional array of Byte". When looking at my dataset as well the datatype for the picture Looks like a series of 1s and 0s.. So essentially I guess what I'm trying to do is convert a picture into an array of bytes so it can passed back?

Adding Records To Access Database?

May 15, 2011

I have been trying for a month to get a row added to an Access database and can not do it. I have the databindings all set and can select different records, but can not add a new one. I have tried BindingSource.AddNew.row() but can't figure out how to add data to the new row, nor does it show in the database.

I have tried

Dim ds As New myDataSet '<---Change this to the dataset name on your form
Dim dr As DataRow
dr = ds.Tables("Students").NewRow

[Code].....

But that doesn't do anything at all. No data added, no errors. I have tried updating a datagrid to be told it can't be updated when bound. I look on google and nothing seems to relate to adding data to an access database when bound to the project through the datasource wizard.
