All,
I am looking for a control that allows modification of a floormap image.
As it stands the floormaps are cad based and BMPs too, but I want to be able to display them in WPF app and modify them (move walls, add pre-defined icons to it for phone points for example).
The intersoft hospital floor is something Id like to do for example but plan needs to be modifiable at runtime. I think that uses KML type files but not sure how to create them from a CAD image (is that possible?). And then how can they be modified in run-time?
Is this possible? Is there a better / easier file format to use for this project?
Its at the design stage so just getting an idea of how to do it! 
Thanks

And here I am looking at when I last posted and thinking it was "the future" (March 30 at 16:35) ... Whaaa ?
Only noticed it was 2015 at little later...

Does anyone have a VS2012 start page? I converted from VS2010 but it's giving me trouble.
Thanks

What do you mean by Start Page, that page where Create new project or Recent projects are given? What problem would it give?

I don't know what sort of trouble you mean, but Google seems to find lots of links[^].

Google gave me lots of links too.
But none seem to deal using the VS2010 resources in VS2012/13.

Unfortunately Microsoft tend to change their systems with each new release, so you (almost) have to start from scratch each time. The only thing for it is to plough through their documentation. I have to say that I did once post a query on a similar problem to their development forum, and got some very useful help from them.

The problem is that all they've provided is the XAML for the start page. No code. It's referring to some resources that are internal to VS2010. And there's no real documentation that I can see.

Assuming it is documented somewhere on MSDN, you have to search quite hard to find it. You could always try the Microsoft developer forum and ask there.

I upgraded a VS 2010 start page to 2010. At the top are 3 objects:
"New Project..."
"Open A Project..."
"Connect To Team Foundation Server"
In VS2010 these are ImageButtons. In VS2012 I can't figure out what they are. So I changed the buttons from:
<vs:ImageButton
x:Uid="ConnectToTSButton"
Margin="15,2,15,2"
Width="Auto"
Content="Connect To Team Foundation Server"
Style="{StaticResource linkStyle}"
Visibility="{Binding Path=TeamFoundationClientSupported, Converter={StaticResource boolToVisibilityConverter}}"
Command="{x:Static sp:VSCommands.ExecuteCommand}" CommandParameter="Team.ConnecttoTeamFoundationServer" ImageNormal="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFS.png" ImageHover="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFSMouseOver.png" ImagePressed="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFSMouseDown.png">
</vs:ImageButton>
to hyperlinks:
<TextBlock Grid.Row="0"
Margin="10,2,15,2">
<Hyperlink Command="{x:Static sp:VSCommands.ExecuteCommand}"
CommandParameter="Team.ConnecttoTeamFoundationServer">
<TextBlock Text="Connect To Team Foundation Server"
FontSize="14"
Foreground="{StaticResource linkColor}"/>
</Hyperlink>
</TextBlock>
But the links are never enabled. I dropped in a button and wire it to the command, and it also is disabled. So the question is, what makes this command enabled?

You are trying to edit Visual Studio's start page?
I don't find any solid reason why to do so... Secondly, if you need help, please see the XMLNS for vs and look for what is provided there to make these buttons run. I would like to say, don't do it. Let it be the actual page.

I didn't ask you if you found a reason to do so.
Let me educate you a bit since you clearly don't know... Starting in VS 2010 MS introduced Start Page templates so developers could create their own start pages. It's a WPF user control and is easy to modify. But they did not provide templates for later versions of VS, so you have to use the 2010 template, which can be difficult.
Please, if you don't have a solution to the problem, don't responde.

I have to display a PDF file in a WPF form. What are the possible ways other than using adobe library.
|
|
|
|

Convert to XPS and use a DocumentViewer.
|
|
|
|
|
Thanks for the answer..
Could you please suggest any free libraries to convert PDF to XPS.
|
|

The easiest way to "convert" a PDF to XPS is to "print" the PDF; where one selects the "Microsoft XPS Document Writer" as the printer / driver.
The XPS printer driver is freely available, as are PDF readers / printers (e.g. Foxit).

Hi folks,
for some weeks now, I'm getting my head around an interesting problem: I'd like to display a text file of several gigs, and let it be editable.
Now - how would you do that? All standard approaches fail, because they rely on the file being fully loaded into RAM, which is impossible with several gigabytes of data. So, I thought I'll create a CustomControl. Basically, I've derived a Control from the Control class, which embeds a FrameworkElement in it's Generic.xaml. This FrameworkElement has a VisualCollection. Now, I hand over a Stream to this control. The Stream must be seekable and writable, otherwise you will encounter an exception. So far, I do the following: I read a chunk of data from the Stream, draw that using FormattedText on a DrawingContext, retrieved by a DrawingVisual. For scrolling, I simply adjust the offset of the FormattedText-function. To achieve seamless scrolling (which is needed, so you can scroll from one buffer chunk to the next without a visible gap), I have a function which calculates the amount of text that fits precisely into a rectangle (e.g. the Window's viewport), so that the rest of the current buffer, together with the next buffer, can be printed on the next rectangle.
But, for the sake of it, I can't find out how I would do standard editing functionality. Because, for the scrollbar and this "chunking" to work, one needs to precompute the needed amount of text to fill the rectangle, which changes when editing the text.
tl;dr:
Do you have a smart concept on hand, together with WPF and C#, to create a TextEditor, which is capable of editing gigabytes of text?

I'm curious, is there any text editor that will handle gb of data?

Not really, at least for Windows. On the one hand, there is Large Text File Viewer, but that is hard to find at the moment. EmEditor is commercial Software, but disables word wrapping and some other options, afaik. And I don't think editing will work.
Then, there is HxD, a Hexeditor. It can even read your disk. That would be the last option, cause with a hex editor, you dont have to deal with line breaks etc. Everything can be set to fixed with. But that would be too easy.^^
A little bit easier to approach would be paging, I guess, instead of scrolling. But that is not so nice, but would be an Option, too.

Personally I would go for chaptering or chunking the physical data on the drive, split it up into edible volumes, store it and when print, ghu forbid, put it back together.
What sort of data is it that is gb big and requires editing? In a text editor!

Hi,
thanks for your thoughts on that.
When splitting up into edible volumes, how would you handle selections across the volumes?
To put things straight - it's not about solving an actual problem. Some time ago, I worked with databases. There is nothing more frustrating than dumping a large MySQL database, just to realize after some hours, that the "CREATE TABLE" statement has been added to the export. Just as an example I've in my mind now.
But there is no customer request behind that. It's just an idea, stuck in my head for a few months now, which I'd like to solve.
What I've got so far: If you use the text approach, chunking would be the best option. There is no need to split the files on the drive, but you would need some kind of controller which would manage the changes being made, map them to the chunks and save them if necessary. This would require paging for navigation, because scrolling would simply be to difficult if you need to take the window size and linebreaks etc. into account.
If I want scrolling, I should take the Hex-Editor approach, that is: Set the textfield to a fixed amount of characters per line, and don't care for linebreaks, etc.
I'm still open for more ideas, though.

It might be worth looking at Memory-Mapped files[^], which would allow you to map sections of the file into memory. No idea how well that would fit with your editor, though.
Once you've finished, this sounds like a good topic for an article!

Hi Richard,
thanks for your comment. I've heard of MMF, but haven't used it before. Sounds interesting, although that wouldn't solve the scrolling part.
And thanks for the hint in terms of an article. I might consider that, why not.
