Hello!

This is my first software project using Adobe Illustrator files as interface elements. I use Microsoft Blend 4 to import those files and build my interface. The problem is simple, when I import (File -> Import Adobe Illustrator file...) and take a look at my elements, they are slightly different from the original. Mostly the colors and gradients. Can someone help me please?

file operation not permitted. access to path is denied silverlight

Hi All,

I have a silver light application where I am trying to access a csv file by using the following way

List<string> listoflines = (List<string>)File.ReadLines(@"C:\Users\amohammad\Desktop\Bugs\30958\tasksandtaskstatuses2.csv");

But its giving my Access Denied message. Is there any way to read a file in silverlight. But I dont want to use the use FileStream or StreamReader. Because I want to read all the lines at a time and assign in the above way.

Is there any way to access the read the files in silverlight irrespective of its access rights. Because here we are just reading the file. I know that if we keep it in my documents then I can read the files. But Can I read the files irrespective of its location and access rights.

Thanks & Regards,

If you think about what you are asking for a minute, you can see that the ability to read any file at any location using a method like this, regardless of access rights, would represent a huge security vulnerability.

As Pete was not very clearly hinting, you aren't allowed to access the local file system in silverlight because thats a security breach. Imagine if any web site could install a silverlight app on your machine and access your c:\documents\bank records.doc and make a copy. Not good!

If you are using SL4, there is a work-around as you can access the local file systems *IF* your app is running with elevated permissions and is trusted. Even then, you only have access to a few folders. Again, a security consideration.

In SL3 and below, you can not access the local file system at all.

You can only get at the file from a user interaction, via the fileopen dialog.

using silverlight,actually it does not allow the client side application to fetch the data from outside the project.The data can be fetched in only two ways ,first if it is stored locally using isolated storage or its a resource file.

WPF path data converter

Curently i have downloaded expression blend trial to see what i do. I have made simple triangle.

HTML

<Path Data="M395.25,283.625 L403.75,295 C403.75,295 388.37515,294.875 388.37515,294.875 C388.37515,294.875 395.25,283.625 395.25,283.625 z" HorizontalAlignment="Left" Height="12.375" Margin="189.891,0,0,188.625" Stretch="Fill" UseLayoutRounding="False" VerticalAlignment="Bottom" Width="16.375" Fill="#FF00B6BA"/>

So my question is, is there a tool that can convert StreamPathGeomtry (Path.Data) into a normal XAML graphic no matter how complex is? I want to see how complex graphics works.

I appreciate any help.

PS: Do not convert this for me.

You mean convert the path into a bunch of line segments? Not sure why you want to do that. Thats the whole point of paths. By the way, that IS a "normal XAML graphic"... Paths have nothing to do with Expression Blend, they are standard WPF objects.

That is what i meant. I know it doesn't have anything with blend.

I may not be able to use Bleend in the future but i want to see how complex graphic comes together.

Ok, well, I don't think anybody really works directly with the path syntax itself because it can get pretty complicated. REALLY complex (by complex, I don't mean a triangle, I mean something along the lines of the Silverlight 5 muscle-man demo) graphics aren't a single primitive. They are thousands of primitives. I forgot the name of the user on here, but there is a guy on here that has put up 4 or 5 demos of complex WPF graphics. Anyways, if you really want to learn the syntax itself (waste of time IMO since the visual tools do it for you Smile | :)

Member 3351906

17-Dec-11 4:07

is it possible to set an adorner for a frameworkelementfactory object ? I have created a frameworkelementfactory of type button. I have registered the click event using addhandler method. In the button click event handler, i got the sender as the button. Then i used the below code:

AdornerLayer adl = AdornerLayer.GetAdorner(btn);

MyAdornerClass acls = new MyadornerClass(btn);

adl.Add(acls) --> // here i am getting error saying specified object is null in the index or don't use this method if VisualChildCount returns 0.

I have overrided the VisualChildCount property in my MyAdornerClass and in the get method, i returned 1.

any idea?

It is a question about WCF RIA.

A Datagrid is binding with DomainDataSource. When I add an entity to DomainContext in client, how can I update the DataGrid(add a row) without connecting to DomainService in server and reload?

How to add option (none) and (new) to itembinding combobox

Loveisasea14-Dec-11 19:49

14-Dec-11 19:49

Usually we use ItemSource property to set comboboxitems automatically. However, we also often hope to attach the following two options to the dropdownitems of combobox.

(None):
Sometimes we need to reset the value to none. but the itembinding combobox doesn't offer. You have to select one value.

(Add);
We also want to add a new value when the itembinding data doesn't include what we want. And we don't want to go to another page to initial this request.

I think it is a common function about combobox. but the bad thing is I can not find a good template for this.

Would anyone know about it? Thanks in advance for your help.
