ComboBox Event To Select From Access Database

Jun 5, 2011

I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box called SelectYearMonth that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.

When I made a report in Access using VBA I coded my calculation as:
Me.ExactReprintTextbox = DSum("Pages", "HBELP_FINAL_Q", "YEARMONTH = " & [SelectYearMonth] & " AND JOBTYPE = 'E'")
While this works great with Access VBA, this syntax does not work in VB 2008 Express. How do I code this in VB 2008 Express?

I need to calculate the sum of all "Pages" of a particular "JOBTYPE" in the Access database for the YEARMONTH selected in the combobox. I have a query in Access called "JobTypeExact_Query" that contains all the pages of that particular JOBTYPE that I need. What I need to do is limit the calculation results to the YEARMONTH selected in the combobox.

VS 2010 - Combobox & Button - Select Option Then Open Website In Browser

Mar 20, 2011

So I've made a program in VB 2010, and it has three comboboxes and a button to view. Now lets say my first combobox is "Type of website". The options are "search engines", "social networking" and "news". The second combobox values would depend on what the first combobox value is selected, like if it was "news" the options would be "technology", "uk", "us", and "world".

The third combobox would then use the values in the first and second comboboxes to give even more values, for example if it was "news" and "technology" the values would be "engadget" etc. Then the view button would open the selected website in an internet browser. How would I code this?

VS 2010 Combobox And Database Messes Up Form?

May 14, 2010

In my Thesaurus application, I use a combobox as a lookup for keywords. On the bottom of the form I have a datagridview that displays the synonyms for the currently selected keyword. The problem I'm having is that whenever I have selected a keyword that has synonyms, or in other words, whenever a keyword is selected that populates the datagridview, and at the same time I try to close the form or remove the keyword my form gets messed up.

Combobox - When Select A Value From The Combobox The Selection Won't Validate?

Feb 22, 2012

I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

Select A Particular Value On A Combobox By Looping Through Combobox Items?

Jan 5, 2012

I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.

Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....

I'm using the following code for doing so:

Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

How To Use Combobox To Select Records

Apr 20, 2010

I have a form with controls on it which are binded to a table, I have records selecters and so on... Just a simple display and edit form(yes I also want to be able to edit them so...) I created this form just by dragging items from the Data sources window.

Now I want to add a combobox which has a list of titles. And here comes the difficult part: When I select a title in the combobox, all the other controls show the matching info(matching to the title), in other words the datatable which is attached/binded to the controls must move to the right record. I have added a query to the combobox , which has two columns: ID and Title. the displaymember is Title and the Valuemember is ID. So I must look in the datatable for the right ID.

Select An Item In Combobox?

Oct 9, 2009

I have a combo box with a list of book conditions. When a book is loaded into the form, the condition the book has needs to be selected. How can I do this? Here's what i have: Excellent Very Good Good Fair Poor just for example, how would i select "Good" WITHOUT USING THE INDEX? The database knows the condition text, and condition id. I need to select the condition in the combo box with either. However, I don't know how to add the condition id to the items in the combo box. How would I do this in Visual Basic 2008? **EDIT** I forgot to mention, although i am using a database, i am NOT using SQL Server. I just need a way to select it with a variable containing either the id or condition.

Combobox To Select 1 Item Datagrid?

Mar 6, 2012

I'm trying to create a Select Distinct query, but i'm getting stuck with either an empy combobox either a filled combobox that displays all the doubles.or a message "System.Data.DataViewManagerListItemTypeDescriptor"

I have a form (form5) with 1 combobox and 1 datagrid.The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname" The collumn "firm" will have some double firms with people in the other collumns ID Firm Fname Mname Lname1 AA John N West2 AA Jim L East3 BB Harry Sick Long4 CC Barry N Klote etc.I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles. I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i choose and doesn't filter. Is there anyone that can give me a clue on how to solve this.

Private Sub Form5_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

I am making a combobox dropdown to filter a report. I am using the table adapter to query the data and fill the report from the selected item in the combobox. However, if the user select index 0 (which is "-Select User-") , then the query should disable the filter and select all users in the database. How would I go about doing this with these 2 conditions?
