Forms :: Calculated Column With SQL
Feb 2, 2010I am attempting to develop a Gradebook that one can use to modify grades and have an average calculated at the end.When you first open the form, you see the database fields in the DataGrid (socSecNumber, firstExam, secondExam, finalExam)I have a button to save the changes made here. The exam grades are null in the database.This seems to work fine, however I have a problem with the calculated column I want to add. I want it to display the socSecNumber and the average for that student. Instead, I get all four fields in addition to the semAverage field. Also, all the grades come up 250 if I fill all the fields in with 100.[code]

View 5 RepliesForms :: Restore Default Color To A Control?
Jan 5, 2011I am building a data entry form. I have code that runs when the 'submit' button is clicked to check that all required fields are populated; if not, the missing fields are hilighted in red:
Sub validatefields()
saveOK = True
If Trim(Me.cmbBillCat.Text) = "" Then
saveOK = False
Me.cmbBillCat.Appearance.BackColor = Color.Tomato
End If
My problem arises when I want to reset the color back to normal. In my form when you click Cancel or move to a new record, all fields are disabled (set to read only) until the 'Edit' button is clicked. Visually this is represented by the field backgrounds being gray. VB.Net automatically changes the text box/combo boxes backcolor to gray when I disable them. However, once I have explicitly changed a control's backcolor, thereafter disabling it does not change its color to gray.
[Code]...
I have tried changing the backcolor to System.Drawing.SystemColors.Window, but the problem is the same. The control whose color has been changed is disabled (won't accept entry) but the backcolor remains white, no matter how many times DisableFields() is issued.

VS 2010 Calculated Fields In A Datagrid?
Feb 17, 2011My program is databound to an access 2007 database. I have a datagridview showing rows as part of my screen and the other part of my screen is texboxes bound to a different table.What I currently have:
1. Date in textbox from one table
2. Age in Datagridview column from another table
I need help with having a calculated date column in the datagridview that will be the textbox date + age (in days) in the datagrid column. I would also need this column to store in my database like any other field also. So if I typed in 2/17/11 into the textbox, and I typed in 2 in the age field, the calculated field would display and store 2/19/2011 in my datagrid and database. My dataset designer won't let me add a date to a string so I'm completely lost. A query calculates it easy in access but when I load the access query in my dataset it doesn't calculate anymore.
