Can we convert vector to C# code? (not to XAML)

Hello,
I'd like to know if it's possible to convert/import an externally-drawn vector as a Path in C# code. So far I've only found how to import a vector to XAML. I'm making a WP8.1 WinRT app and I'm going by what is said on
this page (which is for vector to XAML conversion). The answer says you can't use the XAML code as the Path.Data in code, but is there an alternative way of doing this?
Basically, my app has many instances of ~6 buttons that have a custom icon/image set as their Content. The button instances are created programmatically and inserted into one/more stackpanels on the page. Currently I'm using .png images. But since WinRT
doesn't have OpacityMask I have to supply two versions of each png: one for Dark and one for Light theme. Then I need to check for the Application.Current.RequestedTheme and set the png appropriately. This, and the reported shorter processing time of Paths
is why I'm considering switching.
I'm thinking the Path Data would be from an imported vector (as PathGeometry). And the code that generates the buttons would be
myButton.Content = myPath; instead of myButton.Content = myImage;
But since we can't use the XAML Path Data in C#, I'm very much stuck here.
Is it possible to achieve the same thing through another method? I was thinking that maybe one could create a UserControl containing the path and set the UserControl as the button's Content in code. But I'm unfamiliar with UserControls. Or is there a way to
convert a vector to C# code directly?

Thank you, that's exactly what I want.
But the weird thing is, the Path inside the buttons show up only the first time that they're being rendered on a page. When I navigate to another page with instances of buttons that use the same paths, the buttons become blank... And when I go back to the
page that initially did display the buttons correctly, I find that its buttons are now blank as well! I can replicate this in a blank app.
Here's a basic sample of what I'm talking about:
App.xaml

<Setter Property="Height" Value="19.5"/>
<Setter Property="Width" Value="18.398"/>
<Setter Property="Stretch" Value="Fill"/>
</Style>
</ResourceDictionary>
</Application.Resources>
Above is just one of the Paths that I'm using. Note: its Fill is set to ThemeResource PhoneForegroundBrush.
MainPage.xaml
<Button
Height="100"
Width="100"
Click="Button_Click"
x:Name="btnmainpage" />
Button_Click navigates to BlankPage1 which contains the same button (different name)
MainPage.xaml.cs Constructor
this.NavigationCacheMode = NavigationCacheMode.Disabled;
Windows.UI.Xaml.Shapes.Path mypath = new Windows.UI.Xaml.Shapes.Path();
mypath.Style = (Style)App.Current.Resources["ExponentPathStyle"];
btnmainpage.Content = mypath;
By setting NavigationCacheMode.Disabled I force the page to "build" the button & its content every time I navigate to it. So I'm effectively simulating navigating to infinite "different" (but not really!) pages like this, I think
BlankPage1 contains the same button as MainPage (to prevent confusion, I've called this
btnpage1) which navigates back to MainPage. In BlankPage1's constructor, the code is the same as well, except btnmainpage is replaced with btnpage1.
So the button on MainPage navigates to BlankPage1, whose button navigates us back to MainPage etc. and both pages are not Cached. When I enter the app, the path displays correctly on the button, but upon subsequent navigation the button on either page is
blank. Setting the fill color in code explicitly didn't work either:
mypath.Fill = (SolidColorBrush)Application.Current.Resources["PhoneForegroundBrush"];
Is this a bug or am I doing something wrong here?

Can i set the policy in code not in a policy file

normally starting rmi client with a policy file. and start the client with such JVM parameters: java.security.policy and java.rmi.codebase.
But in jsp how can i specify these JVM parameters.Or can i make the policy in code not in
a file.

You can specifiy inline with code otherwise malicious code would use it the grant all permissions before it wrecks havoc on the system.
When your Servlet engine starts (Tomcat, JBoss, depends on which you are using) there will either be an option to pass in additional policy file, or a policy file will exist inthe servlet engine directory path for you to edit and add your entries to.

Photoshop CC Can't convert to jpegs; image processor not opening

I'm on Windows 7. When I open a psd document in PS CC, I don't have the option to convert to jpeg, and a lot of other types, for that matter. Also, when I click on Tools/Photoshop/Image processor it will not open up. Any suggestions? Thank you.

It was already disabled when I checked. I enabled it and tried again, still didn't work. Anything else that might be wrong? i'm getting desperate lol

Read the characters or String from keyboard input

String or the characters. Please help ....
HanThe keyboard input part is a little more coding envolved. Here is a sample of what can be done if
you know what to implement. It needs three classes
from the java.io package. Well, here is the complete
source code for the 'keyboard input' and a driver
class to test it.
//package consoleclass;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
class Driver
     public static void main ( String[] args)
          System.out.println("Enter a number");
          int number = MyInput.readInt();
          System.out.println("number entered "+ number);
          System.out.println("Enter another number");
          number = MyInput.readInt();
          System.out.println("number entered "+ number);
class MyInput
/**Read a string from the keyboard*/
public static String readString()
     BufferedReader br
       = new BufferedReader(new InputStreamReader(System.in), 1);
     // Declare and initialize the string
     String string = " ";
     // Get the string from the keyboard
     try
       string = br.readLine();
     catch (IOException ex)
       System.out.println(ex);
     // Return the string obtained from the keyboard
     return string;
/**Read an int value from the keyboard*/
public static int readInt()
     return Integer.parseInt(readString());
/**Read a double value from the keyboard*/
public static double readDouble()
     return Double.parseDouble(readString());
}

Can't Order Book. Postal Code not accepted

I've spent days and nights.. creating a Book in Iphoto from my latest vacation.
Now when i'm finished i cannot order since my Postal Code(Zip Code) isn't accepted.
I live in Sweden and no matter what ZIp Code or variations of it i try (believe me i have tried) i cannot get past step2. I always get the dialog that i need to eneter a valid postal code.
I've searched the web and tried (just to get past the second step) postal codes for a few other countries, and the ONLY one working is when i try a US address and ofcourse select USA as the country.
I've tried with a new account, and with an existing account that works fine with itunes... Anyone have any ideas, or have i just wasted days creating a book i cannot order..

Thanks. I might use it soon...
Does it automatically make folders named after the volume labels? And does it handle the conversion of spaces and non-alphanumeric characters to octal codes?
I could read the script but it would be faster for everyone reading, if you leave the answer as a reply.
I also think that there should be some major work done on modernizing the fstab, either by replacing it with a better implementation of file system mounting or changing the file structure and adding in better handling of non-alphanumerics. I don't want to have to look up a stupid octal table every time I type in my labels.

If I was trying to get someone else to do my work,
I wouldn't be posting this saying what I have said
would I? I'm not unwilling to do the work myself.From what was stated in your OP, it seemed that you
were.I'm sorry if it seemed that way. I don't want something for nothing. I've spent MANY hours, which I don't have, trying to work this out. I have hit a point where I don't think my expertise is going to solve the problem. That's why I've turned to some experts who might say something along the lines of, "Hey, I know what that is...you're compiling against... and on the Unix box, it's compiling against..." I was NOT looking for something like, "See the code below that fixes your problem."
The only problem is that I don't have direct access
to the sun unix machines I'm running the app on,
so I can't run a profiler on it. Ah, okay. So the only knowledge you have of how it
performs on those machines is from your instructor
running it and then telling you how long it took?No. I can SSH into the servers and run the program from a command line. But I wouldn't be able to install any profiler programs.
You could ask your prof to run it with -Xprof or
-Xhprof or whatever. Or you could put in a bunch of
timing statements to get a rough idea of which parts
are making it take that extra 39 minute or whatever.is -Xprof a java command line option? If so, I will look into doing that. Maybe it's available on the machines at school. Thanks for that input.

<input type="button" value="submit" name="button" onclick="CONVERT(this.form.data1)">
</form>
</BODY>
</HTML>
can anyone do it for me.
thx in anticipation

Sunish,
On your problem, check in the String class documentation the method replaceAll(), you can solve your problem in just one line of code.
As for why the serious poster(the ones that are here to help, for many year, instead of just disrupting the forum) do not give you code is that they are here to help people learning and not to give free code.
You help a person to learn, when you provide this person with the tools to research and help the person to think out of his problem, so that in the future the learning person can repeat the process by herself instead of going after finnished solution everytime he needs it.
May the code be with you.

How can I convert multiple files at one time and not one at a time

How can I convert multiple files at one time and not one at a time

Hi Plissey1950,
Sorry for the lengthy delay to a response. Are you trying to convert multiple files to individual PDF files at the same time? (not combine them). If so, you'll need to use Adobe Acrobat for this function. The CreatePDF service does not have the ability to convert multiple files to multiple individual PDF files.
Thanks,
David

I recored a video with my ipad, downloaded it to my mac but I cant upload it to Youtube because the format IMG is not a video format. How can I convert it?

How can I convert a video I took with my ipad on the format IMG to a supported format for Youtube?

To upload videos to YouTube we have to make sure videos are in a format that YouTube accepts. Here’s the list of some well-known video formats which YouTube supports:
WebM files (Vp8 video codec and Vorbis Audio codec)
MPEG4, 3GPP and MOV files – (typically supporting h264 and mpeg4 video codecs and AAC audio codec)
AVI (Many cameras output this format – typically the video codec is MJPEG and audio is PCM)
MPEGPS (Typically supporting MPEG2 video codec and MP2 audio)
WMV)
FLV (Adobe – FLV1 video codec, MP3 audio)
But I think you get the wrong video file. iPad recorded video files are in m4v, mp4, mov, avi format but not the img files. Anyway, if you need a video converter, Format factory or iFunia video converter are good choice.
Good luck!

You may be able to default to DOC, but have not tried same.
Since Open Office is 99% same as Word, I use it, or Word, either one. Open Office is a bit less buggy than Word 11'

How can i convert the firefox-history-timestamp in places.sqlite into a normal date format? The firefox-timestamp is not equivalent to the unix-timestamp, that's why I ask. I could not find a conversion function. Does anyone know something about this?

As I opened the places.sqlite with an sqlite-editor I found out that firefox saves the last_visit_date via a timestamp which is 16 digits long. I realized that the first 10 digits are similar to the corresponding unix-timestamp but not equal. So.. how can i convert the firefox-timestamp into a normal date? Or into the corresponding unix-timestamp?

Write a bash script or 'C' program to change the date format and then use the sql update function to receive the stdio output 'where date_field='embeded date value'.
