Generally speaking, not possible. The RichTextBox doesn't support the Word file format. You'd have to save the document in RTF format, then load that version into the RichTextBox. Now, there's another problem. The RichTextBox doesn't support the entire RTF specification. Meaning, while Word will save all the formatting and other goodies in RTF format, the RichTextBox doesn't understand it all and will not render the document properly if the document contains formatting it doesn't support.

That could be a problem. Is there a list anywhere which has more information about this? Some of my coursework uses this setup for convenience, and it's saved using Word, so this could be a possible problem

Hi,
I don't know any details except this one: I have successfully been creating RTF files programmatically containing tables, which Wordpad can display but not create or drastically edit. And AFAIK Wordpad and the RichTextBox are based on the same basic control.
IMO a WebBrowser can show (not edit) a Word document, just like Internet Explorer can.

So long as either Word or Word Viewer is installed, this is true. If not, IE can't display the document and you'll get a Save File option for the .DOC file.

This is really frustrating. I produced some graphs using GDI and vb.net and on the screen they look fine. When you print them off on a black and white printer they look fine BUT on a colour printer the quality is really bad. you can see lines in the colours which is just not acceptable..
I have included the sample code below. I have tried changing to bmp, png etc and it makes not difference.. what am I missing ?.. i can send a copy of the picture produced if anyone can help or you can just copy the code and try running it..
Thanks
Peter

Since you're not doing any printing from your code, the result is going to be up to the printer driver and it's configuration on the client machine.
You're also going to have to show a picture of the result. You can post a link to a pic uploaded to ImageShack or Flickr or any other image hosting service.
Frome what you're describing, it doesn't look like you've got much in the way of options that you have control over.

That looks fine to me, except for the text, which is very low-res, but then you have chosen to use only a small bitmap in Bitmap(340, 230)
Images tend to scale rather well, for text having its rendering delayed as much as possible is advantageous, since in the end it is the printer that knows its actual resolution, the available fonts, etc. Rendering the text early on and in a (small) bitmap isn't good for final quality.
|

I concur with Luc. This looks fine except if you're sending this size image to a printer, it's going to get scaled up, and with it, the tiniest of flaw (which JPG loves to introduce!), will also get scaled up as well.

Thanks for the great comments. The reason the graphic is small is that it is on a asp.net local report page which is generated from a sql database and then presented to the user as a pdf page. They then print this page off.
If I was to make the graphic much larger and then scale the image to fit on a web page will that still suffer from the same printer upscaling problem ?
Do you have any other sugestions or should I drop a message to the reporting services section of the forum.
Cheers
Peter

I would probably make the graph generator able to scale it's own image and code the web page to want an image for "such and such" resolution, and the version that goes in the PDF at a high resolution. Scaling an existing image to do a different job has its problems, both if you scale up and if you scale down. Down doesn't degrade the image as much, but can still introduce "jaggies" and make text look funny.

Hi,
im using Wshell.Regwrite to write registry(vb script) through html page...
but it works fine only when the option "Initialize and script ActiveX
controls not marked as safe" under Tools\internet
options/Security/Customlevel/ActiveX controls and plugIns ,is set to prompt or enable .....and if we set to any other option ie(disable) it fails ie it shows error like .. "ActiveX component cannot create object "Wscript.shell"...
So May i know whether is it possible to create my own ActiveX control(signed) with certificate so that it doesn"t depend on internet options..
if yes pls let me know how to do the same...
pls correct me if im wrong...

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Look at point seven of this link. It's in C#, but you can easily run it through an online converter to get bona fide VB.Net code. Additionally, you could look at this, this and this link

hi all,
i am very confused about the relation between Font and character set.
can any body provide some information(or useful link) which can describe the relation between Font and character set.
Actually i want to know that what is role of Font for any character set?
|
|

|

A character set is a collection of characters which can be used by a particular character encoding, such as ASCII or UTF-8. A font is a complete character set of a single size of a particular typeface

Character Set is a set of characters. Meaning, a set of characters grouped by meaning, function, or other needs. A character set is defined by committe.
A Font (font set) displays a set of characters. The characters can be from one or more "Character Sets". For instance, the font Arial has 24 character sets. A font is created by an individual.
A character can be displayed (or presented) in different ways.
Therefore, we have multiple font sets or Fonts.
Run charmap or select Start>Programs>Accessories>System Tools>Character Map, the "Character Map" application.
Play with the different fonts.
Notice when a clear- or true-type font is selected, the "Character Set" is highlighted.
Play with the different character sets.
Try Arial font with the two character sets "Windows: Western" and "Windows: Arabic".

whether you mean Arial supprort 24 type of character set like unicode,ascii etc? if yes then how can i find that which font support which type of character set(for example how many character set is supported by Font "Courier New")
