I'm wondering if any one knows a way to take two values from within VB and send them to a database. then return a list of values cpu (temp) list of all temp's ( and what is the best type of data base to use for this - it will need to be on the internet )
View 2 RepliesI am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

View 2 RepliesI'm trying to loop through a bunch of checkboxes I have created on my aspx page. I would like to get all the values, and parse them to a string to send to another page as post variables. This is what i have so far:
aspx page:
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox0" runat="server" /> Name</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox1" runat="server" /> Training Year</div>
<div class="ReportsCustomBox"><asp:CheckBox ID="CheckBox2" runat="server" /> Continuity Clinic</div>
etc...
aspx.vb file:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Submit.Click
Dim targetURL As String
targetURL = "report.aspx?"
' This is the part i can't figure out.
' For Each checkbox on page
'if checkbox is checked
'targetURL &= checkboxid & "=true&"
End Sub
My goal is to build another page that will then check these values using Querystring variable, and build a listview out of them. (a report page, that basically lets the user select checkboxes of the columns they want to see on the report).

I'm currently patching an asp.net program where I need to be able to send an image to an SQL Server 2005 DB. It works fine when I use the asp:fileupload control, but the trick is that when the user deletes the image, I'm supposed to replace it with an image from the server saying "empty", in code-behind. I know how to open, use and save text files in vb, but I can't find any information anywhere on how to open an image / binary file in a similar manner so that I can use it as an sql-parameter on the update query. Below is an example of how easy it is to use a file from the fileupload control.

I have an application in which I have one textbox (in this one I write a date like 23.07.2010 ) and a combobox in which I insert a time from the list of combobox (like 12:30, 14:45, etc). I want that when I press a button to send this datetime value in a column of an sql database. I want to send something like (in VB.NET)
sql=" INSERT INTO table_name (column1, column2, date_time_column) values ( val1, val2, '23.07.2010 12:30') "
execute(sql)
So, I have problems when I want to send date/time into sql tables because of the different Regional Settings.

Here is my problem. My controls on the form were created from dragging and dropping one of my tables from the data explorer window onto the form in details form, not gridview. Amongst these controls are four comboboxes whose text properties are databound, but their items lists are not bound. When I click my submit button, all the data is sent to the database except the text from these four comboboxes. I have looked everywhere I can think of and can't figure out why the text from those comboboxes isn't being updated in the db.
