Can't Get The Combo Box To Display The Value From The Query
May 25, 2010
I have a form that queries a database into a dataset then sets textboxes to values from the query. I have a status field I want to be able to control so I created a combo box with typed in values(Active, Inactive, Missing, Broken,Calibration). The purpose of this form is to view the current information on the item and edit if need be. I want to display the current status in the combo box. I can't get the combo box to display the value from the query. How do I do that.

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

I have a data table that looks like this:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
LAGX03 1698 1112 05-07-2012
LAGX04 4598 1555 05-07-2012
LAGX05 2589 3245 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX07 3698 3458 05-07-2012
LAGX08 2589 4587 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX10 3156 1987 05-07-2012
LAGX11 5547 2011 05-07-2012
LAGX12 9456 3459 05-07-2012
Now, I want to execute a sql query that will display the top 5 based on average, so i did this:
SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX03 1698 1112 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
Now, I want to numberize my query result, so it will look like this:
RANK USERNAME ICOUNT IAVERAGE DATE_LOGGED
1 LAGX03 1698 1112 05-07-2012
2 LAGX09 1598 1142 05-07-2012
3 LAGX06 3321 1155 05-07-2012
4 LAGX01 1245 1245 05-07-2012
5 LAGX02 2211 1422 05-07-2012

I am trying to use a Linq Query to pull Data from a Dataset and put it into a Combobox. I am getting a Cannot Convert Type String to Boolean Error and I don't understand Why. So Far I have my Linq query pulling Data from the Dataset but I have not been able to get it into the combobox.[code]The portion of code commented out is what I tried before but to no avail. I believe that the error that is occurring, the LINQ query is pulling all the elements not just the VehicleType. I also was wondering how to use the Distinct Keyword in LINQ, from my searches it seems that it should go after my Select Statement in a new Linq, but my SQL Side says thats wrong.

PROBLEM: I want to only show specific database records based on serveral combo-box inputs from a user. I'm looking to query an Access database from within a form I've created for viewing simple Jpegs of CAD files and pointcloud data. I've never worked with table adapters, SQL statements, or much in the way of databases before and I'm lost.
Do I add a new query and do what I want from a configuration wizard somehow? That method gave me a toolstrip button with no combo-box.Should the combo-box be bound to the table or should it stand alone?Can this be done without the use of a wizard (purely in an event) I've been told what I'm looking to do is rather simple, I'm just unable to find syntax that has worked for me.

I'm fairly new to visual basic and have a problem that is probably quite easy to solve yet I have been unable to do it so far and am about at wits end.I have an access database with a table that contains a list of cities and states. what i would like to do is to populate a combo box on a vb form with a list of the states in the states column. the query that i have is as follows:
SELECT DISTINCT State from Cities I have previewed the data in the dataset designer and it works, i just can't figure out how to make it fill the combo box. i initially created a table with just all of the states and then used a binding source and table adapter to bind it to the combo box, but if I'm able to figure this out this would help with my application going forward

I'm trying to make a database program in VB 2008 and have come across a problem with a query that I'm not sure how to solve. I have a combo box which contains names of teams that are held within the database, when a team name is selected I have 4 queries that will separate players (in that team) by their position, using this information I will then be able to display information about the players in a collection objects so that it can be edited and what not.
My problem is that I need to be able to refer to the records in the query so that I can assign a players details to objects on the form, I've used a piece of code to do so that I used previously to select individual records from a table, however when I click on a team in the combo box it throws up the error: "Could not format node 'ClientQuery' for execution as SQL.". Not being a particularly experienced VB programmer this error doesn't exactly mean too much to me, although I am not exactly sure of another way to tackle the problem.
The code for this query is:
Dim GK(3, 2) As String
Dim c As Integer = 0
For Each Record In GoalkeeperQuery
[CODE]...
All the fields in the query are strings. If this is not enough information I can post the query I used to select the records in the query used above or anything else that's related.

I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"

I've used VB to connect to Excel and get the titles of the different columns in a spreadsheet. These then display in a drop down combo box for the user to choose from. I'm getting lots of empty values in my combo box because not all the columns in Excel have titles. How would I go about telling it not to display them?
Excuse the easy question but I've only started learning to code a week ago.

The user will click the book name in the combo box.
Note: The combo box is separate from datagridview . It is not part of datagridview columns.
Then the datagridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return should be displayed.
The row that will be displayed in datagridview is such that the bookname selected by user in the combo box should match with bname row .
On the same datagridview there will be button with name "Issue" so once it is clicked then this whole data of datagridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"

I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?
