Fill ComboBox From Table In Access
Aug 6, 2010
I am creating a form for entering technical data about a part into an Access database. In the same form I have several ComboBoxs that need to have their lists filled from the same reference table in my database. I have a number and unit field for the twist and bending radius properties. I made the unit fields ComboBoxes and I am trying to bind them to referance table in my database called UnitsLength. The relevant structure is as follows....
Form: NewPartForm
Database: CableDataSet
Main Table: PartMechanical - with fields: TwistNom, TwistUnits, BendingRadiusNom, BendingRadiusUnits
Reference Table: UnitsLength - with fields: Unit, Shorthand, Conversion Factor
First tired the following settings....
Data Source: Other Data Sources > NewPartForm List Instances > CableDatase
Display Member: UnitsLength.Shorthand
Value Member: UnitsLength.Unit
SelectedValue: PartMechanicalBindingSource > [The associated unit field]
But the lists didn't populate.... Then I tried these settings
Data Source: UnitsLengthBindingSource
Display Member: Shorthand
Value Member: Unit
SelectedValue: PartMechanicalBindingSource > [The associated unit field]
But now every ComboBox displays the same value but still stores the data in the proper field... it just sets them all the same.

I think this may be a usual issue but I am not able to find much info. There is a master customer database and a call log database at work. The call log database has two tables that are updated from the master database monthly. Now I am writing this vb frontend for the call log database and cannot figure out the update portion
For p = 0 To maxrowsC (currently around 1000 rows)
With myCommand.Parameters
.AddWithValue("@HEATSeq", dsCallLog.Tables("ConfigDS").Rows(p).Item(0))
[code].....

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?

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I am trying to fill a combobox with data from an xml file. I have it setup on form load to call a loadXMLdata function. In the loadXMLdata function it reads the xml file. I would like to know how I would return each of the elements to populate the combobox. I have mostly done php work and in php i could do an array like this: array[book] = "VB.Net Programming". Is there a way to do something like this with an array such as xmlData("Server 1") = "255.255.255.255"

I am having a problem with filling a combobox with unique values.Im not very good at vb either so I will explain what I have done so far.
1. I added a combobox to my form called Combobox1
2. I clicked the little triangle widget thing on the ComboBox1 set the dataset to MyDATASETDataSet1
3. Display Member: CurrencyCountry, Value Member: FCode, Selected Value = None
4. I fill MyDATASETDataSet1 when the form loads using:
PricesTableAdapter.ComboBoxQuery(CurrencY_DATABASEDataSet1.Prices)
ComboBoxQuery =
SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]
The form does not load, i get the error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.If I replace ComboQuery with Fill Query (which is the default fill command) it displays results....but not unique results, i see the same items being repeated throughout the list in the combobox.I guess my questions are:
1. when you fill a dataset do you need to select all the fields when you are creating your query?
2. if i simply wanted to perform the following lookup:
SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]and set the combobox Display Member: CurrencyCountry, Value Member: FCode how would I do this in the code?
3. how can i change my query to display only unique values, distinct doesnt seem to be working?

I have a form that has three comboboxes in it, cbxStudy, cbxMethod, & cbxAnalyte. When I call the form I load a data table and use that table to fill the comboboxes. I want to assign a value to cbxStudy, then fill cbxMethod by filtering the data table using the value in cbxStudy, then fill cbxAnalyte by filtering the data table using the values in cbxStudy and cbxMethod.
This code keeps failing when the forms New constructor is called, but once the form is loaded the code works great. I indicated below where the code is failing. It's failing because Me.cbxStudy.SelectedValue is = {System.Data.DataRowView} when the constructor is called even though I set the SelectedValue myself.
Public Class frmSelectMethod
Private cv_dt As New DataTable
Private cv_strPrevValue As String

i have the following code to fill two comboboxes using one dataset:
Private Sub sub_cbo_type_load()
Dim ds As New DataSet
ds = cls.cbo_type()
[Code].....
the problems is: whenever the index is changed in one combobox, it's automatically changed in the other one too.

How do you use a parameterized query to make the (last_name, first_Name) appear in the same combo box? I know how do drag them over from the DATA SOURCES menu, but I am trying to combine them. So instead of it being two separate combo boxes with both last_name and first_name), it want it to find the the names with first and last name in the same combo box.
