View 6 RepliesAsp.net - Update Database Based On Gridview Value?
Mar 13, 2012I 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.

View 3 RepliesCreating Objects Based On Database?
Jun 9, 2011I have decided I would start small and make a program that would create a "receipt" list in a listbox and a total. Now, I would like the user to be able to add their own "menu" items. I'm assuming the best way to go about this would be to have them actually add it to a database and then a function in the program will refresh the dataset with the new list. However, this is where my problem lies. How can I tell VB .net 2010 that I want to create a new button (or buttons) on the fly, in an orderly pattern on the form, based on the input from a DB?

Learn To Control Database Based On VB2010?
Nov 6, 2011Recently, I've changed my job to a biological company, they have huge data but managed by Excel, only by Excel. For example, they have hundreds of orders every month, but they just simply record them by Excel. No database concept is used in this company. Excel to manage this is nightmare, only one person can write the file, others can only read the file by ReadOnly. And these data is very easy to be mistakenly modified.
So, since I come to the above Excel-managed company about one month ago, I cannot stop myself thinking apply database.But I have no programming background at all, only used VB6.0 to create some tiny program in High School. Now I started to think whether I can use VB2010 to do this.First of all, I turn this problem to Access, and I learned a lot database design theory from getting to know Access. However, I finally find out that Access can hardly freely create Form like VB (maybe I didn't find out how)
Anyway, I started to study VB2010, to add DataSet to my Form1, and use DataGridView to display data, and to use TableAdapter to modify data. However, it is quite hard to learn, without any systematic books. For example, I am confused about TableAdapter and TableManger, and I don't know how to simply display a modified DataTable by DataGridView control. And SQL search language is new to me as well.
So, I'm wondering if anyone could recommend me any books based on what I would like to learn? Or any tips and reviews?

IDE :: Create Classes And Forms Based On A Database Structure?
May 10, 2010I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains
Open Access Database Based On User Input?
Dec 3, 2009I've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.
