Update Checkboxes Based On Text String?

Mar 11, 2010

i'm trying to refresh a few form checkboxes based on text typed into machinetxt.text with what is currently stored in the database. i put this into the refresh button click event. here is my code:

Private Sub machinerefreshbutton_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles machinerefreshbutton.Click
Dim mycon As SqlCeConnection

[Code].....

i've tried tweaking the select statement but it still gives the error that the machinetxt.text string is not found in the database. Even though i type it in exactly as shown in the database.

Way To Create Empty Data Table / Update Its Contents Based On Columns Not Add Data Based On Addition Of New Rows

Apr 6, 2011

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

Asp.net - Update Database Based On Gridview Value?

Mar 13, 2012

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.

SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1
FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName

[Code]....

It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.

I have tried an update however you cannot use an aggregate in an update as I have found.

Add Text In A List Box Via Checkboxes?

Mar 22, 2010

what i need to do is to add text in a list box via checkboxes. For example if a check box is checked, then a certain text (e.g. "Flea Treatment") gets added to the list box. In my project there are around 15 checkboxes, and not all of the may be clicked. So what I want to do is, when there are values in the list box (Only words!) then I press the Save button and all the values (i.e. all the treatments, e.g. Flea, de-worming, myxomotosis) inside the list box are saved to my database. The table inside the database, is called tblNotes, and has only 4 fields, one of which is a unique ID field, which is the primary key; the other field is the one where I want the values inside the list box, to be saved. As for the other two, they are for standard textboxes, with a fixed length, they are already working.My problem is this: The list box won't save to the database, and I want to know how I could save it. This is the code I have for saving it to a database (btnSave):


Private Sub btnSaveNotes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveNotes.Click
'The purpose is to save the changes made to the record on the screen
'Check if compulsory fields don't contain data, show error message and place cursor back in field[code].....

Auto-update A Listview Based On Reading A Column?

Mar 28, 2012

Is there a way to auto-update a listview based on reading a column?

Requirements:

1) The code must make a call to a user-created "Private Sub" to recalculate

2) Update must be automatic. .SelectedItem or clicking a row will not work

3) The formula function cannot be included in Form_Load

I've got everything working if the user selects a row, then clicks an "update" button using .SelectedItem. But with my current program containing 200 rows, it's not feasible. Simply put, how would I go about updating a listview column (0 in this case) based off a call to a formula, then updating the row?
