PDF Document Procecessing - Demo Sample

In your demo projects, there seems to be a discrepancy between the VB Code and the CSharp Code:

            editor.Position.Translate(defaultLeftIndent * 2, page.Size.Height - 180)
            Using stream As Stream = GetSampleResourceStream("PdfProcessing.telerik.jpg")
                editor.DrawImage(stream, ImageFormat.Jpeg)
            End Using

            editor.Position.Translate(defaultLeftIndent * 2, page.Size.Height - 180);
            using (Stream stream = GetSampleResourceStream("PdfProcessing.telerik.jpg"))
            {
                editor.DrawImage(stream);
            }

Your VB demo project will not compile.

It would be more friendly, if the DrawImage function had a System.Drawing.Image as argument.

[Silverlight Only] How to load UTF-7 CSV data when not supported by Silverlight 4+

I had a problem with loading & decoding UTF-7 data from a CSV file into Silverlight's RADSpreadProcessing. Special characters like 'é' were being flagged as invalid by the Microsoft UTF-8 decoder in Silverlight. WPF on the other hand supports UTF-7 decoding.

With the help of Nikolay Demirev (Telerik support) he pointed me in the right direction with this Microsoft information: Understanding Encodings for Silverlight

Below is the solution that I came up with to auto-identify the encoding and handle UTF-7 encoded CSV files. I hope that it helps others.

Sub ProcessData()

Dim FormatProvider = New CsvFormatProvider

With FormatProvider

With .Settings

.Delimiter = ","

.Quote = """"

.HasHeaderRow = True

.Encoding = New System.Text.UnicodeEncoding

End With

Dim Filename As String = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Telerik Test.csv")

Dim WB As Workbook = LoadWB(Filename, FormatProvider)

'-- do something with the loaded data...

End Sub

Function LoadWB(FileName As String, FormatProvider As CsvFormatProvider) As Workbook

If Not File.Exists(FileName) Then

Throw New FileNotFoundException(String.Format("{0} Not Found.", FileName))

End If

Dim WB As Workbook

If GetFileEncoding(FileName) Is Encoding.UTF8 Then

WB = FormatProvider.Import(GetUTF8(FileName))

Else

Using Data As FileStream = New FileStream(FileName, FileMode.Open)

WB = FormatProvider.Import(Data)

End Using

End If

Return WB

End Function

Function GetUTF8(Filename As String) As String

Dim encodedBytes() As Byte = File.ReadAllBytes(Filename)

Dim enc8 As Encoding = New UTF8Encoding(False, True)

Dim decodedString As String = String.Empty

Try

decodedString += enc8.GetString(encodedBytes, 0, encodedBytes.Length)

Catch e As DecoderFallbackException

Dim sb As New StringBuilder

For Each b As Byte In encodedBytes

sb.Append(Microsoft.VisualBasic.ChrW(Convert.ToInt32(b)))

Next

decodedString = sb.ToString()

End Try

Return decodedString

End Function

Public Shared Function GetFileEncoding(srcFile As String) As Encoding

' Use Default of Encoding.Default (Ansi CodePage)

Dim enc As Encoding = Encoding.UTF8

' Detect byte order mark if any - otherwise assume default

Dim buffer As Byte() = New Byte(4) {}

Dim file As New FileStream(srcFile, FileMode.Open)

file.Read(buffer, 0, 5)

file.Close()

If buffer(0) = &HEF AndAlso buffer(1) = &HBB AndAlso buffer(2) = &HBF Then

enc = Encoding.UTF8

ElseIf buffer(0) = &HFF AndAlso buffer(1) = &HFE Then

enc = Encoding.Unicode

ElseIf (buffer(0) = &HFE AndAlso buffer(1) = &HFF) Then

enc = Encoding.BigEndianUnicode

ElseIf buffer(0) = 0 AndAlso buffer(1) = 0 AndAlso buffer(2) = &HFE AndAlso buffer(3) = &HFF Then

enc = Encoding.Unicode

ElseIf buffer(0) = &H2B AndAlso buffer(1) = &H2F AndAlso buffer(2) = &H76 Then

enc = Encoding.UTF8

End If

Return enc

End Function

The type initializer for 'Telerik.Windows.Documents.Fixed.Model.Fonts.FontRepository' threw an exception

Hello, I wonder if you can help with my issue.

In short, I am getting the exception (as in the post's title) when I get to the following line of code:

document = new RadFixedDocument();

RadFixedPage page = document.Pages.AddPage();

editor = new FixedContentEditor(page); // <<-- exception here

The things to note are:

1. No exception is thrown when the project is run from Visual Studio.

2. The exception is thrown when the merged assembly is run, that is after it has been merged with ILMerge.

3. The merging worked fine UNTIL I have added the Telerik.WinControls.PdfViewer.dll (and the related Telerik.Windows.Documents.Core.dll and  Telerik.Windows.Documents.Fixed) assemblies to ILMerge script and then tried to instantiate the FixedContentEditor when executing the merged assembly.

That is, I have been using ILMerge for months with over 20 merged Telerik assemblies--no problem! It's only now that I started instantiating the FixedContentEditor so I assume it is the merged Telerik.Windows.Documents.Fixed.dll assembly that's throwing a wobbly somewhere.

By the way, the ILMerge throws no errors or warnings and the merging completes just fine. When I then run the merged assembly, it runs fine until I access the function that executes the code snipped above (that is, all other Telerik controls render correctly, etc.).

This seems to indicates it is not an issue with the ILMerge process per se. I wonder if there are some weird WPF dependencies somewhere. Even though it is a WinForms project and according to the Telerik documentation the FixedContentEditor can be used in WinForm applications, I noticed I had to refer to WindowsBase.dll in the project references because of two silly lines of code which refer to the System.Windows.Size struct.

    maxWidth = page.Size.Width - defaultLeftIndent * 2; <<-- does not compile without WindowsBase.dll reference add
maxHeight = page.Size.Height - currentTopOffset * 2; <<-- does not compile without WindowsBase.dll reference add

I have attached the merge script below and also screenshots my project references and successfully completed ILMerge process.

Thank you!

import existing word template

hi,

I'm trying to import an existing word template into a RadFlowDocument, edit it by filling the merge fields and display it on the screen (read-only).
Can anyone please assist me with this. The word templates also contains a header, which contains images and text boxes.
The File.OpenRead command returns an error, as it is unable to read the document into a stream (object reference not set to an instance of an object).
