I need to read a employee database and display some fields in a windows forms application - that is fine except the varbinary(max) image. I need to move forwards and backwards through the records (some images are null).
The problem I have is using the dataset to obtain the information for the image convertion. I can find loads of code to use a button(s) to get & convert the image - this does not help me.
Help will be greatly appreciated.
Below is some of my code:
Public Class Form1
Private Sub GraduatesBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GraduatesBindingNavigatorSaveItem.Click
Me.Validate()
Me.GraduatesBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.Graduates_DatabaseDataSet)
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'Graduates_DatabaseDataSet.Graduates' table. You can move, or remove it, as needed.
Me.GraduatesTableAdapter.Fill(Me.Graduates_DatabaseDataSet.Graduates)
End Sub
Private Sub GraduatesBindingNavigator_RefreshItems(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GraduatesBindingNavigator.RefreshItems
End Sub
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
Private Sub PhotographLabel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
Private Sub SurnameTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SurnameTextBox.TextChanged
End Sub
Private Sub FillBysurnameToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Try
Me.GraduatesTableAdapter.FillBysurname(Me.Graduates_DatabaseDataSet.Graduates, SsnameToolStripTextBox.Text)
Catch ex As System.Exception
System.Windows.Forms.MessageBox.Show(ex.Message)
End Try
End Sub
End Class

this is not a question about Visual Studio, is it?

Not really sure how to get this working I'm so close but it's driving me insane.
I've got some ASP.NET server controls that I have written in VS 2008 Pro.
The controls works great and I have all the design time functionality I want except for one thing.
All the controls inherit from a base control which has a single String property called Zone.
i have a windows form attached to a verb that in an nut shell grabs the actual zones that are available for use from the database and displays them in a simple combobox with an ok and cancel button.
the problem is when i select the zone and click ok the Properties Window updates the value of the control's Zone property however the source view's HTML for the control does not update and i have no idea why.
here's the applicable code:
This is the code for the Form attached to the verb.
public partial class ZoneSelector : Form
{
public String Zone { get; private set; }
public ZoneSelector(System.Web.UI.Control c)
{
InitializeComponent();
DesignerIBC3DataContext DC = new DesignerIBC3DataContext();
var Zones = DC.Zones.Where(zone => zone.siteID == new DesignTimeHelper(c).AppSettings["siteID"]).Select(zone => zone.zoneName);
ZonesComboBox.DataSource = Zones;
}
private void OKButton_Click(object sender, EventArgs e)
{
Zone = (String)ZonesComboBox.SelectedValue;
this.Close();
}
}
Here is the event handler for the verb
public override DesignerVerbCollection Verbs
{
get
{
if (DVC == null)
{
DVC = new DesignerVerbCollection();
DVC.Add(new DesignerVerb("Get Zone", new EventHandler(OnGetZones)));
}
return DVC;
}
}
void OnGetZones(object sender, EventArgs e)
{
ZoneSelector ZS = new ZoneSelector((System.Web.UI.Control)this.DesignControl);
DialogResult DR = ZS.ShowDialog();
if (DR == DialogResult.OK)
{
this.DesignControl.Zone = ZS.Zone;
}
}
So to recap the form and verb seem to work fine as the correct zone is updated into the Properties Window but the source view does not update the HTML for the control.
If anyone has a clue please let me know.
Thanks

Hi,
Is there a simple way or shortcut (if so, what is it  ) to open the files/ move to the "next" file containing definitions of a particular partial class?
Currently I'm using "Find All References" when right-clicking the partial class name. If there is a better way, I'd like to find out.
Googling didn't yeild any results for this so I suspect the functionality does not exist.
Thanks.

Hi,
this seems to work:
1. right-click on the class name X and choose "Go to definition"; this brings you to the X constructor.
2. move up in that file to the class statement
3. right-click on that class name X there and choose "Go to definition"; this puts the "partial class X" locations in the "Find symbol results" pane, where they are clickable.

This is driving me up the wall and I can't find a solution. The C# code editor property places #region directives, but #if/else/endif directives always jump to the beginning of the line instead of the current indentation level.
What gives? Any way to change the default??

I always think that is the best way, so you can clearly see where some code may be parsed out by the preprocessor.

I disagree. It just looks stupid when you have code indented 5 or 6 tabs (i.e. deep in a nested loop) and the compiler directives are at the beginning of the line. It becomes difficult to see what lines are even affected at that point.
Seeing what code is parsed out is easy because visual studio grays out and collapses the region.
Either way it just looks messy...I much rather have them indented like the region tags.

Yes, but these things are just based on personal preference; as with most things there is no right and wrong.

My bad; my original wording should have said "my preference" rather than "best".

I've created a Crystal Reports report in a Visual Studio 2003 project and I'd like to preview it without running the project everytime. Is there a way to do this?

Hello All,
Visual Studio is behaving kind of strange, the problem occurred when we refactored our solution, we just organized our xslt style sheets and placed them in a separate folder but the changes we made to them doesn't reflect unless and until we move them to their previous location. Are we missing something?

So I just rebooted. Before the reboot, I was running VS 2008 just fine. After the reboot, I get the dreaded "Cannot find one or more components. Please reinstall the application."
I've not uninstalled anything that VS might shout at. I hate this. I hate VS. I hate MS.
Any clues? 
EDIT - a clarification: VS tells me absolutely nothing more than the above Cannot find one or more components. Please reinstall the application.

Well without giving us a clue, no. What components is it complaining about?

Thanks for the reply - I wouldn'thave asked the question if VS had given me any clue whatsoever in the first place... 
It tells me absolutely nothing more than "Cannot find one or more components. Please reinstall the application."
I was hoping someone had seen it recently due to some mysterious behind-the-back auto-update of some important file when Windows update kicked in some night or so.

My apologies.
Usually when a poster says this, it means they did not read the error message, and could not be bothered to rerun the test to reproduce it. I've not had this with any of my own systems.

No problem. I've had my share of questionees not giving enough background, so I can recognise your standpoint.
