ZipArchive Exception type with bad password

Is there a reliable way to detect a bad password when opening a ZipArchive? I'm currently getting an InvalidOperationException when reading the first entry, and the message is a generic "Invalid data". Exception shared below.

Telerik.Windows.Zip.InvalidDataException occurred

Table - Text Font Size

Hello,

I am struggling setting the Font Size of all the Text in my Table that i am drawing inside of my pdf document. It seems like it is defaulting to either 10 or 12... I need to display at least 4 columns in a row, and i want to reduce the font size to at least 8. Is there any way to do this without setting up a unique block each time and then trying to add it to Cell, and Row , etc...

My code looks like this below:

---------------------------------------------------------------------------------------------------------------------------------------------------------

Dim RevenueTable As New Table()

Dim firstRow As TableRow = RevenueTable.Rows.AddTableRow()

firstRow.Cells.AddTableCell().Blocks.AddBlock().InsertText("---------------------------")
firstRow.Cells.AddTableCell().Blocks.AddBlock().InsertText("--------------------SERVICE")
firstRow.Cells.AddTableCell().Blocks.AddBlock().InsertText(" DETAILS-------------------")
firstRow.Cells.AddTableCell().Blocks.AddBlock().InsertText("---------------------------")

Dim secondRow As TableRow = RevenueTable.Rows.AddTableRow()
secondRow.Cells.AddTableCell().Blocks.AddBlock().InsertText(objReceipt.SERVCODE(i))
secondRow.Cells.AddTableCell().Blocks.AddBlock().InsertText(objReceipt.SERVNAME(i))
secondRow.Cells.AddTableCell().Blocks.AddBlock().InsertText(objReceipt.SERVQTY(i))
secondRow.Cells.AddTableCell().Blocks.AddBlock().InsertText("")

Dim ServiceCodeRowDesc As TableRow = RevenueTable.Rows.AddTableRow()
ServiceCodeRowDesc.Cells.AddTableCell().Blocks.AddBlock().InsertText("Revenue Desc")
ServiceCodeRowDesc.Cells.AddTableCell().Blocks.AddBlock().InsertText("Item Price")
ServiceCodeRowDesc.Cells.AddTableCell().Blocks.AddBlock().InsertText("Qty")
ServiceCodeRowDesc.Cells.AddTableCell().Blocks.AddBlock().InsertText("Revenue Amount")

{....lines of code removed ....}

editor.TextProperties.FontSize = 8
editor.DrawTable(RevenueTable)

------------------------------------------------------------------------------------------------------------------------------------------------

The font size is not 8.

[Solved] [Silverlight] Umlaute (ä ü ö) in PDF Export

Hey,

I'm using a RadfixedDocument to create a Report and the PdfFormatProvider to export the Report to PDF.

Everything works fine, except for german Umlaut Letters (ä, ö, ü). They just disappear in the generated PDF. I couldn't find a switch in the Export Settings or anything else, can you give me some directions?

Cheers,

Jens

Hi,

I created predefined docx template for reports I want to generate. The template is loaded into RadFlowDocument for more modifications. Somewhere in the middle of the document I want to insert a picture. How do I use the RadFlowDocument editor to move that specific location of the document and insert that image?

Best regards,

Host UI Element in RadFlowDocument?

Hi,

I'm trying to use RadFlowDocument (2015 Q2) to create summary reports. Before switching to RadFlowDocument, I used to work with normal WPF FlowDocument and I'm able to host UI elements (such as charts) in it. Now, I'm trying to do the same thing with RadFlowdocument, but I can't host a UI element in it.

Is there any way to make RadFlowDocument host a UI element?

Thanks,

Ahmed

16. using (ZipArchive archive = new ZipArchive(stream,

17. ZipArchiveMode.Create, false, null))

18. {

20. foreach (var fileInfo in new DirectoryInfo(parFolderToArchive).GetFiles())

23. using (ZipArchiveEntry entry = archive.CreateEntry(fileInfo.Name))
