VS 2008 Storing Information To An Array Or ArrayList And Displaying Each Item In Label?
Apr 22, 2010I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

[2008] Filtering And Displaying A Database?
Jan 20, 2009I want to be able to use this program to filter through a list of doctors, and based on what doctor you select, only show the patients who see that doctor.Here is what I have so far, the database has a column with just the doctor names so I thought I should be able to filter it by that and show the patients, but none show up. I don't get an error and it seems to refresh, but nothing ends up in the schedule.
vb
Public Structure ScheduleOwner
Dim _doctorname As String
Dim _description As String

Actually I just realized I don't think I loaded the data from the database as the form loaded. I tried doing that, but get an error where I called for the data to be loaded. I added the code where I try loading the databases."No value given for one or more required parameters."
Displaying Information From An Array?
May 30, 2010I started programming in VB many moons ago, but I put it down about a year ago. I picked back up a project I was working on a few years ago and Visual Studio 2008 Pro had to convert it. It seemed to work just fine but I wanted to make it "look .NETish", so I simply copied all the controls and code into a new project.The new project won't display information stored in static arrays on a Rich Text Box. The arrays are declared public in a code.vb file and the array is populated in the load event for the main form.I've tried inserting a "test" button to see if I could somehow get it to display trying a few different things. Essentially:
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click
Dim test As String = Gems(0)
[code].....
Has array conventions changed or something in the past year or so? How do I extract the information contained in Gems() that I have so maticulously entered so long ago
Displaying Information In A Grid
May 13, 2009I am working on a Windows Forms Application and I have got stuck and wondered if anyone can provide some much needed direction. [Code] The user makes a selection of, say region, and then a DB layer sends back some linq IQueriable(of sometype) for a particular month. I wanted to add a month column each time they select a month.
I can't seem to do this too well with a datagridview, I have tried making a class that holds the measure as string and value as decimal and then create a list of these to bind but then if I add a new one I have problems as it just overwrits the origional one. I could just place a series of textboxes and fill them as I go but this seems like it is a problem waiting to happen kind of way. What I really need is some sort of grid that is expandable.
WMP Control Displaying ID3 Information?
Nov 19, 2009I remember using a one liner, something along the lines of AxWindowsMediaPlayer.currentMedia.Artist or something similar, that required no complex processing of the file, to display artist, album and song title. Using the WMP 11 control. It's been a while since i needed to use that and i've lost it.
Was wondering if anyone knew what that was, and if im mistaken, what easy method, without processing strings, files etc. there is in getting ID3 tags.

[2008] Query Database Using SQL And Displaying Results In Datagridview?
Sep 25, 2009I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code.

Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:

VS 2010 Displaying Information During Drag Event?
Jan 27, 2011I have a form set up for drag and drop. The dragging and dropping is working nicely, as it allows the user to put a pair of dots onto a rectangle, which is exactly what it is supposed to do. However, I would like to give them some information about where they are dropping the points. My first thought was that I could use a tooltip. However, it appears that tooltips are not displayed during drag events. The tooltip works well, and is showing what I want, once I have released the mouse button, but not before then. The only other alternative I can think of, and it is not a very appealing alternative, is that I have some labels elsewhere on the form to display the information.
View 9 RepliesVS 2008 Extracting Information From 'database' (?) Behind Website?
Feb 3, 2010My university has a website that students can use to check stuff like their lesson schedules, latest grades, exam times, etc. Just general information about you and your study (after you have logged in of course).For interested, this is the website (not much use without a login obviously, but still): [URL]I have been thinking lately that it would be nice to have a desktop application that could give me the same information. However, I have absolutely no idea how that would work, and whether or not it is even possible. I mean, technically it should be possible for me to get the information (how else does the website get it) provided it is not secured (even when using the correct login details). I am sure the website communicates with a database somewhere. Does that mean I could theoretically also communicate with the database (probably: read from it only, not write) for example by executing queries?If that is possible, how do I figure out which queries to use for the different pieces of information? Obviously I don't know the details of the database so I can't just send a random query and expect it to work...

View 1 RepliesDisplaying Images From A Database?
Sep 13, 2009I'm currently attempting a project where I need to display a series of images from a database, in thumbnail form, then fullscreen when they are selected. Next/Back arrows will be used to navigate through different pages of images. These images will be across a number of categories each one with a different table in the database. It is very important that the user can change the images in the database.
Rather than have a number of different pages and each image designated to a picturebox, I was wondering how I could make it so the program just displays the next 6-8 images from the database in the same picture boxes, giving a message when the it reaches EOF, This way the number and order of the pictures can be changed just by changing the database.
