View 4 RepliesI have a program in which I want to have the user enter two percentages and display the data matching the criteria on a new form. The query would be:
Select *
From Corrosion
Where corrpct1 >= {column in database} OR
corrpct2 >= {column in database}
The way I currently have it written is to display only one row of data. I need to display any number of rows that meet this criteria. My current code is:
Private Sub btnDetails_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDetails.Click
Dim form As New frmDetails()
Me.Hide()

1. How can I do my query to incorporate the user entered criteria (in the where statement)?
2. How can I display ALL of the data instead of just one line?

View 12 RepliesI am struggling to understand fully, I need to bind data from an access database to a datagridview.

I really don't understand this fully.

I have a database that dynamically loads from Access into a datagridview. I have to enter data manually into one column in this datagridview. I need to be able to perform calculations to this data, for example I need to sum the data in this column, sqaure it and substract it from individual sqaures of the data in the cells. I should be able to sum it sum(22,33,44,53,67,23)^2-sum(22^2,33^2,...23^2). The number of columns keep changing depending on the database I choose to load, so I need to code this dynamically too. I am not really a VB person. I did the same in excel using Visual Basic and I am trying to do it in this Visual Basic environment.I built a tool in excel(VBA) that do some statistical calculations and data analysis and I am trying to build the same in Visual Basic.

View 1 RepliesI have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 5 RepliesI am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
