We change our Print-Preview from VB6 to vb.net c1Preview Version 2.0.20072.42005.
For Formulardesign we have our own Listgenerator. So I must print different kinds of objects in succession. This works fine with RenderImage, Renderline, Rendertext..., but not with RenderRichText. There is a pagebreak after each .ADD and the next Position is on the top of the next page.

I have tried to get the height of the RTF-Text to calculate the next Y-Position with RenderEmpty, CalcSize ... but nothing works.

What can I do, and is it also possible to import Word-Files. Thanks         

‘--------
Dim fileReader As System.IO.StreamReader
Dim sRTFString As String = ""

fileReader = My.Computer.FileSystem.OpenTextFileReader(sRTFFile)
sRTFString = fileReader.ReadToEnd

Dim rrtf As New RenderRichText

rrtf.X = uLeft
rrtf.Y = uTop
rrtf.Width = uWidth
rrtf.Rtf = sRTFString
m_C1DOC.Body.Children.Add(rrtf)

Try using CalcSize("1In",Cq.CqPreview.Unit.Auto)

That gives me a height (and 300) for the width.

 Hi, thanks for response. I try CalcSize(Unit.Auto, "1Mm")  but I always get the same value for Height for different RTF-Files.

There are different values when I try CalcSize(Unit.auto, unit.Auto), but the Value is (after conversion) not the real size of the text.

It seems that I can get good valuesw for height using

CalcSize("1in",c1.c1preview.unit.auto)  - I ignore the width resulting from "1in"

and I get good values for width using

CalcSize(c1.c1preview.unit.auto,"1in") - again I ignore the height from the "1in"

 Thanks, it works. I have misunderstood your first reply. Is there also a possibility to get the Y Position of the current page after the RTF Text is rendered. I try m_C1DOC.Body.Document.CurrentPage.Y but the Value returned is 0. The vsview7 have a Proberty for this.

regards
 

 I have attached small example that loads RTF file and uses CalcSize() to determine size of RTF.

Also it demonstrates properties:AvailableBlockFlowHeight, AvailableBlockFlowWidth and CurrentPageArea. 

Hi, thanks for reply.

I try the code from your example in my project and it works fine, but there is one exeption

Each of my RenderRichText have there own Mesurements   rr.X = uLeft, rr.Y = uTop and  rr.Width = uWidth. The Height I get with calcsize and it works fine.

But, when I get a Pagebreak the Height of Calcsize is the whole RTFText-Height. And not only the part of the new Page, so I try AvailableBlockFlowHeight to get the available vertical space to calculate my new CurrentY-Position to render some text, graphics, next rtf and so on.

This works in your sample, when I use the Mesurements I get an Error on RenderBlock: "Object can't be rendered with RenderBlock() method, its coordinares are non auto."  (also in your example)

When I  use the RenderRichText, I get alway the same Values of AvailableBlockFlowHeight  for each RTFText.

RenderBlock method can be used only when coordinates of object (X and Y) specified as auto. You can use RenderDirect method if you want to render object not in main flow.

As I have understood you use StartDoc() / Render... / EndDoc() methods to generate a document.
In this case you can get all measured info directly from object after RenderBlock() or RenderDirectMethod().

Sorry for late reply. Thanks for your help, it works fine. I get all measurements. But the following happens:

The long text is printed on the second page. The RenderFragment.PageNo is 2 and the Pagecount of the Document is also 2, when I Print the next text with rendertext (also with renderdirect) the text is printet on the first Page ????

 I add rendertext by renderblock in your sample, it works fine! The Text is on the new page, but I can't put the rtftext with y / x position on the page. An error occurs

With renderdirect i can set the position of the text, but I have the problem describe above

Thanks, regards
