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.

I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.

I am new to vb.net and I have looked at other topics. I cannot find the answer I need. OK I have a combobox named cboRaceDesc and five checkboxes (CkRaceAfricanAmerican, ChkRaceAmerican Indian, ckRaceAsian, ckRacePacificIslander, and ckRaceWhite). I was going to post an image, but I cannot.cboRaceDesc has two options...Hispanic and Other. If the user selects Other then they have to choose one of the five checkboxes or it will raise an exception when the record is being saved. I am assuming I would generate the code under the "save" button. I know I need to gather the following information in my code:
If cboRaceDesc.SelectedValue = Other Then
<I am not sure how to code the logic regarding the checkboxes>
<I know I need to use multiple else/else if statements>
<I know towards the end I would generate the exception>
End
Can anyone help me fill in the blanks or point me in the right direction?

I know how to pull data from an access database and place it into a combobox, but I am trying to make certain that I dont have multiples of the same information.
Like one column is for countries of origin.
United States
Canada
Mexico
In the combo box, it should only list the United States only once, not multiple times.

I have an access database that has columns where the data is a tickbox, i would like to select all the ticks from one row. Erm i'll try and be more descriptive: The database has the family of aircraft in the first column and then each subsequent column is to do with a calculation and i want to assign boolean variables the value of true if the tick box is checked and false if it isnt. How can i assign the values of the tick box to a variable?
I have this query:
CODE:
Where accessConn is the connection to the database and cmbFamily.Text is the row in the column family that i want to select all the KG_IFP values from.If you're not living on the edge, you're taking up too much room

I'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.
