I encountered a strange "problem" or maybe a "bug" in Android.
I use the ClipboardManager for my App quite often.
But if I use it within some seconds twice, I always get a NullPointerException.
What I think is that I Clipboard is notalready filled when I am accessing it but this seems to be a really silly idea...
Has anyone encountered the same problem, or am I doing something wrong?
I get the error at String text = item.getText().toString();
Error message:
java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.String java.lang.CharSequence.toString()' on a null object reference
at at.co.netconsulting.leotranslater.SettingsActivity$1$3.onPrimaryClipChanged
Thanks for every hint or help in advance!
Here is a piece of my code:
final ClipboardManager myClipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
myClipboard.addPrimaryClipChangedListener(new ClipboardManager.OnPrimaryClipChangedListener() {
#Override
public void onPrimaryClipChanged() {
ClipData cp = myClipboard.getPrimaryClip();
if(cp.getItemCount()>0) {
ClipData.Item item = cp.getItemAt(0);
if (item == null) {
Toast.makeText(getApplicationContext(), "Item is null", Toast.LENGTH_LONG).show();
} else {
if(item!=null) {
String text = item.getText().toString();
Toast.makeText(getApplicationContext(), "Sie suchen nach dem Wort: " + text, Toast.LENGTH_LONG).show();
Intent msgIntent = new Intent(SettingsActivity.this, ServiceTranslator.class);
msgIntent.putExtra("ClipBoardData", text);
startService(msgIntent);
}
}
}
}
});
}
I think this could be the solution.
String text = item.coerceToText(getBaseContext()).toString();
Looking into the documentation, it is said that
if all you want is the textual representation of the clipped data, you
* can use the convenience method {#link Item#coerceToText Item.coerceToText}.
I hope that will solve my problem!

Im trying to query all elements of subclass in Unity. I have found SDK constraint or missing something here.
According to documentation querying subclasses is possible.
> var query = new ParseQuery<Armor>()
.WhereLessThanOrEqualTo("rupees", ((Player)ParseUser.CurrentUser).Rupees);
query.FindAsync().ContinueWith(t =>
{
IEnumerable<Armor> result = t.Result;
});
Im however using relation table and cannot specify
Here is my code:
IEnumerator LoadMyDesigns(Action<RequestResult> result) {
ParseUser user = ParseUser.CurrentUser;
ParseRelation<Design> relation = user.GetRelation<Design>("designs");
Task<IEnumerable<Design>> task = relation.Query.FindAsync();
while (!task.IsCompleted) yield return new WaitForEndOfFrame();
if (task.IsFaulted) {
//error
foreach(var e in task.Exception.InnerExceptions) {
ParseException parseException = (ParseException) e;
Debug.LogError("Error message " + parseException.Message);
Debug.LogError("Error code: " + parseException.Code);
result(new RequestResult(true, parseException.Message));
}
}
else {
result(new RequestResult(true, new List<Design>(task.Result)));
}
}
And error:
ArgumentNullException: Must specify a ParseObject class name when creating a ParseQuery.
So the question is how do I specify query subclass type when using relations?
Thanks.
I've struggled with the same problem and in my case I needed to provide the propertyName again in de GetRelationProperty call.
For example:
[ParseFieldName("designs")]
public ParseRelation<Design> Designs
{
get { return GetRelationProperty<Design>("Designs"); }
}
Try querying your designs Table.
Make a new query for class "Designs" where equal("owner", PFUser.currentUser())
This should return all of the designs for the current User.
I have a Synchronous plugin that runs when any opportunity create/delete/update. And in Plugin if any error comes i have made a function which insert log into database.
In table one field if EntityId, so i am writing the following code :
foreach (PropertyBagEntry entry in (IEnumerable<PropertyBagEntry>)context.InputParameters.Values)
{
DynamicEntity entity = (DynamicEntity)entry.Value;
foreach (Property property in (IEnumerable<Property>)entity.Properties)
{
if (property.GetType().Name == "KeyProperty")
{
str4 = ((Key)entity.Properties[property.Name]).Value.ToString();
break;
}
}
}
In str4 i am getting EntityId of current process.
But it gives one exception very frequently :
Unhandled Exception: System.InvalidCastException: Unable to cast object of type
'ValueCollection[System.String,System.Object]'
to type 'System.Collections.Generic.IEnumerable`1[Microsoft.Crm.Sdk.PropertyBagEntry]'
And i have identified that the following line is giving error
foreach (PropertyBagEntry entry in (IEnumerable)context.InputParameters.Values)
Anyone have idea to convert this line in another way ?
My understanding is that you want to get the GUID of current record, if this is the case then you can do it as:
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
try
{
if (context.MessageName == "Create" || context.MessageName == "Update")
{
if (context.InputParameters.Contains("Target") && (context.InputParameters["Target"] is Entity))
{
Entity currentEntity = (Entity) context.InputParameters["Target"];
Guid currentRecordGuid = currentEntity.Id;
}
}
}
catch (Exception ex)
{
}
}
I believe the type of that collection varies from one message to another. If you are looking to get the Id of the record within a plugin, this helper function may come in handy:
public static Guid GetEntityIdFromContext(IPluginExecutionContext context)
{
string messageName = context.MessageName;
if (context.PrimaryEntityId != Guid.Empty)
{
return context.PrimaryEntityId;
}
else if (messageName == "Create")
{
return new Guid(context.OutputParameters["id"].ToString());
}
else
{
return context.PrimaryEntityId;
}
}
If that doesn't help, would you mind providing the message that causes the error?
If
Unhandled Exception: System.InvalidCastException: Unable to cast
object of type 'ValueCollection[System.String,System.Object]' to type
'System.Collections.Generic.IEnumerable`1[Microsoft.Crm.Sdk.PropertyBagEntry]'
is truly your error, than your issue is not with line
foreach (Property property in (IEnumerable<Property>)entity.Properties)
but with line:
foreach (PropertyBagEntry entry in (IEnumerable<PropertyBagEntry>)context.InputParameters.Values)
The type of context.InputParameters.Values is not castable to an IEnumerable
This might be a bit too specific for here and I may need to contact redactor support but i've seen other questions about redactor here so i figured i'd give it a shot ...
Ok ...
So i'm trying to get get image uploading to work following the example here ...
http://imperavi.com/redactor/docs/images/
My client side code ...
$("textarea").redactor({
focus: true,
imageUpload: '/MyController/UploadImage'
});
My MVC controller action looks like this ...
public JsonResult UploadImage(object image)
{
// Do something with whatever that was i got from redactor
var result = new { filelink = "" };
return Json(result);
}
The problem is ... what did redactor actually give me?
Was it the whole file? a chunk? i can't seem to tell because the object has no type information at all and the raw post information seems way too little to actually be a whole image file.
Has anyone had any experience with this / actually done it before?
I don't really want to setup php on my server for this 1 function.
EDIT:
Ok a bit more digging reveals that if i pull the underlying Request object it has a files property which apparently contains my posted image file.
I think i might be able to figure it out from here.
Where I get a code block in place i'll post it as an answer.
You are receiving a HttpPostedFileBase object. Here is my implementation:
jQuery:
$('#blog-post').redactor(
{
imageUpload: '/blog/images/',
imageGetJson: '/images/locations/blogs/'
});
Then in the controller:
public ActionResult Images(HttpPostedFileBase file)
{
// Verify that the user selected a file
if( file != null && file.ContentLength > 0 )
{
// extract only the fielname
var fileName = Path.GetFileName( file.FileName );
// store the file
var path = Path.Combine( ImageLocation.BlogPicturePath, fileName );
file.SaveAs( path );
}
return Json( new { filelink = ImageLocation.BlogPictureUrl + "/" + file.FileName } );
}
ok um ... i think im there ...
This needs a bit of cleaning up and I don't expect you guys to understand what goes on under the bonnet of my custom DMS code but just assume it takes the stream and returns a FileInfo object and in theory this should work for you too ...
public ActionResult Upload()
{
// this object is specific to my system but all it does is
// stream the file to a path on the server (code not needed for this Q)
var dmsService = _kernel.Get<IDMSFileSystemService>();
List<FileInfo> savedFiles = new List<FileInfo>();
for (int i = 0; i < Request.Files.Count; i++)
{
var file = Request.Files[i];
using (file.InputStream)
{
savedFiles.Add(dmsService.AddFromStream(file.InputStream, file.FileName);
}
}
var result = savedFiles.Select(f => new { filelink = f.Path}).ToArray();
return Json(result);
}
Suprisingly simple right ... :)
I am trying to perform a relatively simple task: to wait until a page redirect is complete. Just seen another answered question on the subject, where an advice is to wait for a particular text on the latter page to appear (IF I've got it right). If so, how about waiting till window.location will be changed? Is it better? Worse? Less applicable? Any other idea? just curious, if needed, can mark this question as a community wiki.
Thanks!
Yes I've encountered this problem many times when using Selenium. There are 2 ways I worked around this problem. First off you can actually change the implicit wait time. For example given this piece of code:
Actions builder = new Actions( driver );
builder.click( driver.findElement( By.className("lala") ) ).perform();
This code will throw an exception if at the point it's called there are no elements that could be found to match the "lala" class. You can change this implicit wait time with:
driver.manage().timeouts().implicitlyWait( 5, TimeUnit.SECONDS );
This makes the driver poll for 5 seconds instead of failing straight away. If the element still can't be located after 5 seconds then the action will fail. Of course you can change that setting. I found that this method works okay the majority of the time. Most of the time you don't care about the whole page loading, just a certain part.
I also wrote another function which is GetElementByClassAndText which will do the same as implicit wait on an element except it also checks the containing text as well to allow finer detailing of what you want:
public static void waitAndClick( WebDriver driver, By by, String text ) {
WebDriverWait wait = new WebDriverWait( driver, 10000 );
Function<WebDriver, Boolean> waitForElement = new waitForElement( by );
wait.until( waitForElement );
for( WebElement e : driver.findElements( by ) ) {
if( e.getText().equals( text ) ) {
Actions builder = new Actions( driver );
builder.click( e ).perform();
return;
}
}
}
And the corresponding Function it uses:
public class waitForElement implements Function<WebDriver, Boolean> {
private final By by;
private String text = null;
public waitForElement( By by ) {
this.by = by;
}
public waitForElement( By by, String text ) {
this.by = by;
this.text = text;
}
#Override
public Boolean apply( WebDriver from ) {
if( this.text != null ) {
for( WebElement e : from.findElements( this.by ) ) {
if( e.getText().equals( this.text ) ) {
return Boolean.TRUE;
}
}
return Boolean.FALSE;
} else {
try {
from.findElement( this.by );
} catch( Exception e ) {
return Boolean.FALSE;
}
return Boolean.TRUE;
}
}
}
I realise that you're using Selenium in Ruby but hopefully some of my code (at least conceptually) is transferable and helpful to you.
Monitoring the value, returned driver.get_location did the job perfectly to me.
Apparently, from what I've understood in my 5 mins peeping into the code was that window.location.href value is monitored under the hood.
You can use this function, it will re-load the current page ( after was redirected):
driver.getCurrentUrl();
I need to read stuff from an Outlook msg file. Currently I'm using a class from CodeProject.com project to accomplish this, since deploying VSTO and Outlook on a server is not an option.
This class gets To, From, CC, Subject, Body, and everything else I need from the msg file, except Date information (such as Received Date and Sent Date).
There is some (really, really low-level) documentation on how to get stuff out of msg files on MSDN, but it's a little beyond the scope of this project and doesn't mention dates at all.
Ideally I'd be able to have a drop-in replacement for the class I am using now (OutlookStorage.cs in the previously mentioned CodeProject) or be able to modify the existing class a bit. To modify, I would need the correct 4 character hexidecimal prop identifier for received date. For instance, Subject is listed as PR_SUBJECT = "0037" and Body is listed as PR_BOY = "1000".
If you're using OutlookStorage.cs from CodeProject, then add the following:
private const string PR_RECEIVED_DATE="007D";
private const string PR_RECEIVED_DATE_2 = "0047";
...
/// <summary>
/// Gets the date the message was received.
/// </summary>
public DateTime ReceivedDate
{
get
{
if (_dateRevieved == DateTime.MinValue)
{
string dateMess = this.GetMapiPropertyString(OutlookStorage.PR_RECEIVED_DATE);
if (String.IsNullOrEmpty(dateMess))
{
dateMess = this.GetMapiPropertyString(OutlookStorage.PR_RECEIVED_DATE_2);
}
_dateRevieved = ExtractDate(dateMess);
}
return _dateRevieved;
//return ExtractDate(dateMess);
}
}
private DateTime _dateRevieved = DateTime.MinValue;
private DateTime ExtractDate(string dateMess)
{
string matchStr = "Date:";
string[] lines = dateMess.Split(new String[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
foreach (string line in lines)
{
if (line.StartsWith(matchStr))
{
string dateStr = line.Substring(matchStr.Length);
DateTime response;
if (DateTime.TryParse(dateStr, out response))
{
return response;
}
}
}
return DateTime.MinValue;
}
I think the Aspose library will do what you want, ok it a 3rd party lib so may not be what you want. There are a few vbs scripts around that get basic infomation out of msg files that could be translated.
Got a hint from this:
string fullFileName = "c:\message.msg";
DateTime dateRevieved = new DateTime();
StreamReader sr = new StreamReader(fullFileName, Encoding.Default);
string full = sr.ReadToEnd();
string date;
int iStart;
int iLast;
string caption;
//This -should- handle all manner of screwage
//The ONLY way it would not is if someone guessed the -exact- to-the-second
//time that they send the message, put it in their subject in the right format
while (true) { //not an infinite loop, I swear!
caption = "Date:";
if (full.IndexOf("Date:") > -1) { //full shortens with each date is removed
string temp = "";
iStart = full.LastIndexOf(caption);
temp = full.Remove(0, iStart + caption.Length);
full = full.Substring(0, iStart);
iLast = temp.IndexOf("\r\n");
if (iLast < 0) {
date = temp;
} else {
date = temp.Substring(0, iLast);
}
date = date.Trim();
if (date.Contains(subject) || subject.Contains(date)) {
continue; //would only happen if someone is trying to screw me
}
try {
dateRevieved = DateTime.Parse(date); //will fail if not a date
break; //if not a date breaks out of while loop
} catch {
continue; //try with a smaller subset of the msg
}
} else {
break;
}
}
This is kind of a hack compared to the ways you can get other things from msg files using something this lovely project. Still, it's stood up to everything I have thrown against it, and as noted the -only- way to fool it is to put the exact to-the-second date in the subject line in the proper format.
to combine your two posts I would suggest the following solution:
To modify, I would need the correct 4 character hexidecimal prop identifier for recieved date. For instance, Subject is listed as PR_SUBJECT = "0037" and Body is listed as PR_BOY = "1000".
Look for "007D".
Use the method you posted in your second post on the received data to eliminate the problem when the same (date) string is inside the subject.
I have to mention that this method doesn't seem to work on internal eMails: In mails I receive from colleagues, there is no substg1.0_007Dxxxx-Property.
Here, the date seems to be hidden in substg1.0_0047xxxx.
All the best!
