View 6 RepliesLinking Pictures To A DataBase?
Aug 1, 2010How do I go about linking a picture to a database? I'm using VB 2008 Express and SQL Express.I want the user to click a button when editing a recipe; the button click will then open some kind of dialog where the path to a picture will be selected. Then a button on the dialog will be clicked by the user and the picture will be saved to a folder in My Documents called "My Recipes" at the same time the recipe will be renamed using the Title and ID of the record being edited ending up with a name like "Nick's Milktart 237.png" (preferably with a space between "Milktart" and "237"). Also at the same time a link to the database must be created to a field called "Picture".I have never tried linking pictures before, I understand the app. will respond much faster this way as to imbedding the picture into the database.
View 10 RepliesAdding Pictures To An Access Database?
May 25, 2009I have a program for school that links to a database. They are listings of real estate and in the browse of the database I have pictures that can be scrolled through as well. The pictures are added to my access database as OLE objects and then just linked to a picturebox to be displayed. However, I'm wanting to add another functionality and allows the user to upload a picture that can be added to the record as well. But I think I'm having a conversion problem.This is what I have right now that is working...but I would like to be able to change that nothing into something.
Public Sub AddToDatabase()
CheckType() 'Convert radio button selection to string
'Sends table adapter items to add.
'Input Order: SELLER, AGENT, PRICE, DATE AVAILABLE,
[code].....
Experimenting, I've tried just addressing pictures from my.resources but the errors I get are... "Type System.Drawing.Bitmap cannot be converted into1 dimensional array of Byte". When looking at my dataset as well the datatype for the picture Looks like a series of 1s and 0s.. So essentially I guess what I'm trying to do is convert a picture into an array of bytes so it can passed back?

VS 2008 Pictures Over Pictures Over Background

What isn't working for me is the panels are slightly overlapped and one will always be on top of the other. it is transparent so you can see the back ground, but not the panel underneath it when it has a picture in it.
View 6 RepliesIDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?
Jan 17, 2011I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.

View 4 RepliesRetrieve All Parents From The Database?
Nov 17, 2011I am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:
Public Class Parent
Public Property Id As Integer
Public Property Name As String
[code]....
I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:
Dim firstParent = (From q In db.Parents Select q).First()
For Each child In firstParent.Children
'Do something
Next
The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...
EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.

Forms :: How To Retrieve Values From The Database
Jun 7, 2012i am new to vb.net and dont have any idea about using datareader.i am right now doing a project on vb.net and am facing an issue.i have a form, where in i have to select the matching records from the database and show it in various textfields. as far as the query execution is concerned, i have successfully completed it, but i am facing an issue now. Suppose, i have an Id of a student, and he has registered for 3 courses, when i give the query something like select students.studentid,courseid,midtermmarks,finalterm marks from marks,students where students.studentid=course.studentid;it gives me multiple records.my doubt is, when i get multiple records, and which is true(in the case a student has registered for multiple courses), how can i traverse through the resultset and fetch the values in the respective textfields.
