Changing appointment time format to military time

Hello,

Is there a way to change the default appointment times to use military time instead of regular time? So instead of the appointment time showing 1:00 - 2:00 it would show 13:00 - 14:00.

Kind regards,

David

Fields aren't rendering

Hello,

I have a PDF that contains fields that I have added with Acrobat. If I put values in those fields and display the PDF with the Viewer, neither the fields nor their values have any kind of representation on the display. How do I get these to show up?

To clarify, the rest of the PDF renders fine. It's simply the fields and their values that aren't showing up at all.

Thanks!

RadRotator centering images

I've got a lot of images I need to load in from a directory into a project where I display a full-screened radrotator on a secondary monitor. I want to be able to show a slideshow of pictures, but I need them to properly fit the screen, and I'd like ones that are strange sizes to be horizontally and vertically centered. All of this seems to be working with my code so far except the centering part...

Here is my code:

Imports System.Windows.Forms

Imports Telerik.WinControls.UI

Imports System.IO

Imports System.Security.Cryptography

Public Class formSlideshow

Private Sub ShapedForm1_Load(sender As Object, e As EventArgs) Handles Me.Load

Me.FormBorderStyle = FormBorderStyle.None

Me.Bounds = GetSecondaryScreen().Bounds

Dim screensize As New Drawing.Size(Me.Width, Me.Height)

RadRotator1.Size = screensize

RadRotator1.Interval = (CInt(Val(formSettings.Interval)) * 1000)

If LoadImages() = True Then RadRotator1.Start()

End Sub

'--Get size and location of secondary monitor

Public Function GetSecondaryScreen() As System.Windows.Forms.Screen

For Each windowscreen As System.Windows.Forms.Screen In System.Windows.Forms.Screen.AllScreens

If Not windowscreen Is System.Windows.Forms.Screen.PrimaryScreen Then

Return windowscreen

End If

Next

Return Screen.PrimaryScreen

End Function

'--Load images into radRotator

Public Function LoadImages() As Boolean

Try

Dim imageslist As New List(Of String)

'--Get employees personal images

For Each employeeimage As String In Directory.GetFiles(formSettings.EmployeeDir)

If Path.GetExtension(employeeimage) = ".jpeg" Or Path.GetExtension(employeeimage) = ".png" Or Path.GetExtension(employeeimage) = ".jpg" Then

imageslist.Add(employeeimage)

End If

Next

'--Get default images

For Each defaultimage As String In Directory.GetFiles(formSettings.DefaultDir)

If Path.GetExtension(defaultimage) = ".jpeg" Or Path.GetExtension(defaultimage) = ".png" Or Path.GetExtension(defaultimage) = ".jpg" Then

imageslist.Add(defaultimage)

End If

Next

'--Randomize order of images

imageslist.Sort(New Randomizer(Of String)())

'--Add images to radRotator item list

For Each imagefile As String In imageslist

Dim newimage As Image = Image.FromFile(imagefile)

Dim rotatoritem As New RadImageItem()

rotatoritem.Image = ScaleImage(newimage, 768, 1366)

RadRotator1.Items.Add(rotatoritem)

Next

Return True

Catch ex As Exception

Return False

End Try

Return False

End Function

'--Shrink images to fit screen, proportionately

Public Function ScaleImage(ByVal OldImage As Image, ByVal TargetHeight As Integer, ByVal TargetWidth As Integer) As System.Drawing.Image

Try

Dim NewHeight As Integer = TargetHeight

Dim NewWidth As Integer = NewHeight / OldImage.Height * OldImage.Width

If NewWidth > TargetWidth Then

NewWidth = TargetWidth

NewHeight = NewWidth / OldImage.Width * OldImage.Height

End If

Return New Bitmap(OldImage, NewWidth, NewHeight)

Catch ex As Exception

Return Nothing

End Try

Return Nothing

End Function

End Class

Public Class Randomizer(Of T)

Implements IComparer(Of T)

'--Insures different instances are sorted in different orders

Private Shared Salter As New Random() '--Only as random as your seed

Private Salt As Integer

Public Sub New()

Salt = Salter.Next(Integer.MinValue, Integer.MaxValue)

End Sub

Private Shared sha As New SHA1CryptoServiceProvider()

Private Function HashNSalt(ByVal x As Integer) As Integer

Dim b() As Byte = sha.ComputeHash(BitConverter.GetBytes(x))

Dim r As Integer = 0

For i As Integer = 0 To b.Length - 1 Step 4

r = r Xor BitConverter.ToInt32(b, i)

Next

Return r Xor Salt

End Function

Public Function Compare(x As T, y As T) As Integer _

Implements IComparer(Of T).Compare

Return HashNSalt(x.GetHashCode()).CompareTo(HashNSalt(y.GetHashCode()))

End Function

End Class

Customized Appointment

Hi,

I would use RadScheduler in an application to show and edit work shifts. I'm using Telerik Q2 2015, Visual Studio 2013.

My question is, is it possible to somehow add some UI controls (labels, check boxes, buttons etc.) to the appointment (e.g by inheriting an own appointment class), so that the user would be able to do some edit actions on the appointment straight away without opening any appointment edit dialog?

Regards,

Pirjo

Pasting a row with readonly columns behaves incorrectly

If I have a row with columns marked as read only and try to paste to it, the column will be skipped causing an undesired behavior. Is this a bug? Is there a workaround for this? I have attached screen shots demonstrating the behavior. Notice that my last column is blank after the paste.
