Get Program To Interface With A Database?
Mar 8, 2011
for my A2 computing project, I need to get my program to interface with a database. Now I'm having a problem in updating records on the database. Here's what I've got so far.
Sub LockProgram()
'this updates the program to be locked, to prevent peoples trying to force their way in.
'it is simply some basic validation and an update statement on the database
If loginAttemptsToday >= 5 Then
[code]....
My program will read from a database perfectly, it will delete and add rows, but it simply will not update?

I have been reading about design patterns and application architecture and im told that I should program to an interface instead of implementation. This i understand. So I figured I would start with something small. Never programmed with an interface before. So I want to create an encryption program that will allow the user to select which method to encrypt it with, AES, DPAPI, etc. I started designing the Interface but I am unsure if I am doing this right. [Code] Also, when it comes to the DPAPI implementation, how is the client supposed to supply the Protection Scope? I didn't think this should be in the interface as it only applys to the DPAPI.

I'm making a VB.net program via a text file and I'm compiling it using vbc.exe via command line. I'm trying to get just a simple program to run in the background of my computer. Problem is, it displays the annoying console window. How do I get nothing to show? No form, no console?

Is it possible to have a "Install Wizard Interface" in a program made in VB.NET? So you first has some boxes so the user can fill in, then when he click next, new controls comes up, without changing/opening/closing windows? I know about tabbed wizard, and thats not what i want.

This may seem like an obvious answer, but I can't seem to find an answer. I have this code in VB.NET[code]...
The problem with this is that in C#, it would seem you have to name the function the same as the interface function you are implementing. How can I call this method EncryptionVB instead of Encryption, but still implement the Encryption property?

Strategy on how to structure a VB.net GUI app. I have a application that is basically an interface to a database. It is comprised of a TabControl with 6 tabs, each tab has a few custom controls and performs a business operation on the database.
Tab Functions:
CODE:
Common Code Functions:
CODE:
Currently I've got most all of the operations built into event handler functions on the GUI thread. I'd like to move to a more object-oriented structure for code reusability and easier multi-threading.
I'm struggling with a few design things:
What objects / classes makes sense? Are there industry-standard best practices or design patterns around separating GUI and backend functionality? Any particularly good articles I should read? Is BackgroundWorker the best way to execute the backend functions?

We have two systems, one is created in VB.Net 2003 and the other is created in VB6. Both systems are client/server desktop application system. There is a requirement that we need to send and response data to each systems. The data will come as result of process of each system and then transfer it to the other system. These is formatted in a message format. Is it likely to become socket programming? how can I send and response data between servers?

I have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this

I'm trying to hone up on my (beginner) coding skills & I would prefer that the the 'Designer coding window', not the 'Design window', wouldn't interfere with these studies. Sometimes it's there & sometimes it's not. I don't understand it at this point & would prefer it wasn't there. All I need is the 'Design window' & the 'regular coding window'.

I am trying to draw an image from a MS Access database by use of e.Graphics.DrawImage(New Bitmap()). In my database Row 0 Item 1 holds the path to the image I want to draw.
My current code looks like this:

Private Sub pnlStart2_Paint(ByVal sender As Object, ByVal e As_ System.Windows.Forms.PaintEventArgs) Handles pnlStart2.Paint
e.Graphics.DrawImage(New Bitmap(ds.Tables("Track1").Rows(0).Item(1)), 3, 3)
End Sub
When I run my program I get the following message in my code: Illegal characters in path how I can draw the image from the database?

I have an existing vb.net application which uses a home grown database. The database has over 60,000 unique multi-field records in it.The user can search in each field using drill-down to find a record, and then can add that record to a separate database.(60,000 collectibles described in a master database. User can drill down by category, manufacturer, year produced, etc. to find a record and then add it to their own 'collection', 'wanted', 'have for sale', or 'spares' database for record keeping.)
Instead of having them drill down, I would like for them to be able to perform a search and have all of the results (any amount of matches from 1 to 60,000+) appear on a scrolling form with a checkbox next to each so that they can simply check any that they want and do a mass add to their list databases.
The part I cannot figure out is how to have vb.net (2008) create a variable length scrolling form with the results, and how to identify the checkboxes (generated by the system for search matches) to see which, if any, have been checked by the user.

VB 2010 Express + MS Access 2003
today I successfully configured an interface to work with a test database I created in MS Access 2003. The database consists of only 8 records with 10 fields.
I used the basic built-ins with VB 2010 to build the interface in a simple form which shows only 6 of the 10 fields. It all seems to work well, that is the connection string built correctly, and I can run the program and view the individual records. My trouble is that when it goes to the 1st record it's actually the 3rd record in the database. And when I go to the last record it's actually the 2nd record in the database and the next to the last record is actually the first record in the database.
why the program seems to start at the 3 record and shifts the first two records to the end. All the records show up, it's just that they are somewhat out of order.

I've been having huge problems having a VB.NET Windows Forms program run as a scheduled task under XP SP3. The program runs when I set the task up to use my non-admin network username and password, I can see the interface fine (albeit without the desired results - the program requires access to remote shares). When I set the task up with the network administrator account credentials, the task is "Running" but I do not see any interface. It doesn't error - it just kind of sits there happily in the background.

Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?
