If you want to know the cursor position at all times (regardless of over which Control or Form the cursor may or may not be), simply check Cursor.Position in a timer tick handler. The timer can be a child of your app's main Form.

That's extremely vague. What do you mean by "didn't get success yet"? You need to be specific when seeking assistance. Also, show the code you've tried.

Hi SA,

By "C# binding" I meant Xamarin offers C# bindings to the Android SDK and allows C# code (e.g. developer defined callbacks) to be invoked by Android callable wrappers. Is this not true?

Please see this cool free book on Xamarin Forms by Petzold.

Xamarin generates IL which is packaged in the .apk (in the case of Android) and runs on top off Mono. The process of converting IL to a form consumable by Dalvik (and the newer Android VM) is transparent. For all practical purposes, the .apk generated by Xamarin is no different than one generated when building a native app.

IMHO, the nice thing about Xamarin is that it allows me to leverage my C# skills and the .NET framework. Caveat: I still need to know the Android API (which is not hard to pick up) in order to build Android apps. The same applies for iOS.

Edit: Xamarin Forms controls translate to native controls.

> Can i write once in Xamarin GUI and run on all 4 platforms including Windows desktop?
No.  Windows desktop (WinForms/WPF) is not supported.

Essentially, only UI code written using Xamarin Forms is portable across iOS, Android and Windows Mobile.

/ravi
Ravi Bhavnani at 6-Apr-15 12:14pm View
   
1) Correct.  PCLs are used to build shared business logic.

2) No, everything written in Xamarin is NOT cross platform! Xamarin.IOS is the C# binding to iOS.  Xamarin.Android is the C# binding to Android.  This allows you to access the standard iOS and Android APIs from C#.

I expect the Android and Windows Forms apps will both need to communicate with a common server or at the very least, a networked file store that's accessible to both clients. The file store is an error prone and cheesy solution.

Patrick, you may want to consider using Xamarin Indie edition with Xamarin Studio (instead of VStudio). That's the path I'm likely to follow once I restart working with Xamarin. Like you, I'm interested in Android dev only.

/ravi
Ravi Bhavnani at 24-Jan-15 0:36am View
   
OG, why use Java when you have a more powerful and elegant language (C#) at your disposal? Use Xamarin Studio (instead of VS) with the Indie license. IMHO, that beats going through the hassle of using and configuring Android Studio or Eclipse and settling for an inferior language.

Ravi Bhavnani at 14-Jan-15 12:05pm View
   
My point is, once an image file has been shown in a PictureBox, the file is locked until the PictureBox is garbage collected (e.g. when your app exits). If you use the suggestion in the link (the link works fine) your file will not be locked. This will allow it to be moved/deleted/renamed.

The Reports table will have columns:
- ReportId (identity)
- ReportingUserId (FK to User.UserId)
- TargetUserId (FK to User.UserId)
- ReportText (not null)
- TimeCreated

This will let you query the Reports table for reports by/for a specific user and/or reports issued within a certain time frame and/or reports containing specific text.

I apologize. I was thinking ListView, not ListBox. Sorry.

/ravi
Ravi Bhavnani at 28-Oct-14 13:36pm View
   
You're right, Sergey - the code doesn't compile in its current state.

But IMHO, initializing a and b (to get the code to compile) would not really change the values of c and d, as they would "change" from zero to zero, since declaring an int initializes it to Int32.Default. The optimized version of the compileable code would (IMHO) be an empty statement.

What do you mean by that?

/ravi
Ravi Bhavnani at 5-Sep-14 9:55am View
   
I don't recommend your approach.  By creating a static TextBox, you're declaring a single instance for all instances of Form1, which is clearly incorrect.  Instead, create a TextBox using the toolbox, and follow the instructions in my solution.

To pass a Form1 reference to Form2, do the following:

(1) Add a public Form1 property to Form2.
(2) When you create an instance of Form2 (from Form1), set the value of that property.
(3) Perform step 3 as mentioned in my solution.

If what I've said doesn't make sense, I recommend you read up on the basics of C# and Windows Forms. That will help you implement your requirements.

/ravi
Ravi Bhavnani at 18-Aug-14 7:46am View
   
No, I assumed you would define sndplayer outside the scope of my answer.

The problem is, it's very unlikely that your timer will fire when it's EXACTLY 6:00:00.000 am. For this reason, you should play the sound the first time the time (to the nearest minute only) is 6:00, and then disable the timer.

In that case, you'll need to inspect the JavaScript that's injecting the content (most likely by making an AJAX call) into the page and make that call from your webservice to get that data.

/ravi
Ravi Bhavnani at 25-Jul-14 18:47pm View

It isn't clear what you want to do. What do you mean by "calculate km/hr in C#"?

It's a tool I'm building. Didn't want have to interop with IM. Also tried AForge, but it expressly indicates it doesn't have a drop shadow filter.
Ravi Bhavnani at 11-Sep-13 17:23pm View
   
Thanks, Pete! That works as described. I was hoping to write a GUI-less command line app that would add a dropshadow to a collection of images, but I think the key is to have a DrawingVisual that requires a physical screen. Thanks again!

Pete, I'm trying to port the dropshadow filter in this VB .NET article http://www.codeproject.com/Articles/313143/VB-NET-Image-Filters to C#. i.e. I'm trying to build a shadowmaker that will operate on a bunch of .png image files.

/ravi
Ravi Bhavnani at 11-Sep-13 15:05pm View
   
Adding a drop shadow to a text string is not the problem I'm having. I want to add a drop shadow to an image.

/ravi
Ravi Bhavnani at 11-Sep-13 15:04pm View
   
That's not the problem. My original image *is* being loaded (confirmed because the generated file looks exactly as the source image). The problem is writing the modified (dropshadow'd) bitmap.

/ravi
Ravi Bhavnani at 11-Sep-13 14:31pm View
   
The Opacity property defaults to 1.0. A FileStream is a Stream.

I don't understand what you mean by "Start with the transparent image and overlay (or print) source image.". My source image has a transparent background. I want to add a drop shadow effect to that and print the resulting image.

/ravi
Ravi Bhavnani at 11-Sep-13 14:05pm View
   
Yes, I know that works. :) What I'm trying to do is save the modified image to a file. That doesn't seem to be working. (My end goal is to write a command line app that will add a shadow to a large number of images.)

/ravi
Ravi Bhavnani at 11-Sep-13 13:11pm View
   
If you look at my code, you'll notice it's functionally identical. I'm not using a Grid because I don't need to enclose the Image in one. If I give the encoder a BitmapFrame created from "bi", the file contains the original (unmodified) image, so I know my scaffolding is correct.

If you post your project I can take a look at it. There's no reason why the .Text.Length property should only "count up to 9".
Ravi Bhavnani at 27-Apr-13 9:52am View
   
It doesn't count up to only 9. Most likely, the AutoSize property of your label control is False, which limits the number of characters displayed. Change it True so that the label can grow to fit the size.

Your question doesn't make sense. A progress bar is used to indicate the progress of an operation and has nothing to with opening a new form. Did you mean you want to close the current form and display a new form when your progress bar indicates the process has completed?

If a desktop app would suffice, you could write a simple app that periodically checks the db for new deal records since the last check, much like an email checker app. The app would run in the system tray and display a visual notification (and even open the browser to the app's login page, if configured to do so) when a new deal is written.

You may want to consider using a ListView control with its View property set to LargeIcon. That will give you the ability to display images and text and also drag/arrange the icons in a grid. I'm assuming this is the kind of functionality you're looking to implement.

There's no magical library that will make it easy to build an app that works like an electronic smart board. At the least, you'll need to have a server and client component, where the server listens for and broadcasts changes to the data on the whiteboard to all connected clients. This is non-trivial at best and doesn't allow for a "one-size-fits-all" solution.

You may want to consider having a background thread load images (into Image objects), then set the loaded Image into the PictureBox. This has 2 advantages: (1) your UI will not be locked and (2) the image file will not be locked by the .NET PictureBox. See this method:

///

/// Loads an image from a file without locking the file.

///


/// <param name="filename">The filename.</param>

/// The image.

public static Image ImageFromFile (string filename)

{

using (FileStream stream = new FileStream (filename, FileMode.Open, FileAccess.Read)) {

return Image.FromStream (stream); }

}/ravi
