I am having a weird issue.
I am trying to bind to an image object. I can bind the RenderTransform perfectly. But the OpacityProperty will not bind correctly. I don't get errors but opacity will not update or change while the TranslationTransform will. I have no idea why:
Dim alpha As New Double
alpha = 0
Dim vImage As Image = CreatevImageControl()
Dim translation As New TranslateTransform(0, 0)
myGrid.Children.Add(vImage)
Dim binding1 As New Binding()
binding1.Source = translation
vImage.SetBinding(Image.RenderTransformProperty, binding1)
Dim binding2 As New Binding()
binding2.Source = alpha
vImage.SetBinding(Image.OpacityProperty, binding2)
alpha = 1
translation.X = -150
How would your OpacityProperty know if alpha has changed?
Automatic updates with Binding relies on notification when a property changes. Either with a dependency property or a class implementing INotifyPropertyChanged.
So in your case, alpha needs to be a dependency property or the property of some class that implements INotifyPropertyChanged.
Your TranslateTransform will notify the binding about the update, since "X" is a dependency property of TranslateTransform. Thus, the binding can hook up a change event and update the binding target changes occur.

I wrote a code to break links to the source excel file for my powerpoint deck, the macro works well except for 2 charts. Both the charts are on the same slide (which is not uncommon) and are line charts. The charts need to be manually updated but the data resides in a excel file only. Not sure what am I missing. This is the code that I wrote
Sub SavePPT()
Dim objPP As Object
Dim objPPFile As Object
Dim sld As Object
Dim shp As Object
Dim shp1 As Chart
Dim newshp As Shape
Dim pptChart As Object
Set objPP = CreateObject("PowerPoint.Application")
objPP.Visible = True
Set objPPFile = objPP.ActivePresentation
objPPFile.Save
Application.EnableEvents = False
For Each sld In objPPFile.Slides
For Each shp In sld.Shapes
If shp.HasChart Then
shp.LinkFormat.BreakLink
On Error GoTo 0
End If
Next
Next
Application.EnableEvents = False
For Each sld In objPPFile.Slides
For Each shp In sld.Shapes
If shp.Type = msoLinkedOLEObject Or shp.Type = msoEmbeddedOLEObject Then
shp.LinkFormat.BreakLink
On Error GoTo 0
End If
Next
Next
objPPFile.SaveAs ("Location" _ & Format(Now(), "MM-DD-YYYY") & ".pptx")
objPPFile.Close
objPP.Quit
Set pptChart = Nothing
Set objPPFile = Nothing
Set objPP = Nothing
End Sub
The chart might be in a placeholder, in which case none of your code will act upon it. If the shape's .Type = msoPlaceholder (ie, 14), check the shape's .PlaceholderFormat.ContainedType property to see if it's a linkedOleobject or .HasChart etc.
BTW, an msoEmbeddedOLEObject won't have a .LinkFormat object to call on; I suspect you have some error handling code that's obscuring an error there. In any case, I'd limit that check to just msoLinkedOLEObject.
Thanks for you help. I realized it later that those 2 slides have a lot of text boxes on them and when I consolidate some of those textboxes the issue was resolved.
I have project with win auth and i use "securityTrimmingEnabled" option for detect to which parts of menu user have access.
I set site map node properties:
siteMapNode.ParentNode.Title = entity.Parent.Title;
siteMapNode.ParentNode.RouteValues["id"] = entity.Parent.Id;
And if "securityTrimmingEnabled" is false, everything is ok and i have correct url in map path(/portfolios/facility/57), if "securityTrimmingEnabled" is true, title of node is ok, but "id" param is not correct(/portfolios/facility/0)
How i can resolve this issue?
This is basically the same issue described here.
The AuthorizeAttributeAclModule is accessing the Url property and causing it to be request cached, so setting properties that affect the URL afterward (such as in a controller action) has no effect.
Option 1
Move the code that sets the RouteValues["id"] into a IDynamicNodeProvider implemenation. This will load the values into the shared cache at application startup (and when the cache expires), but it also loads them before the AuthorizeAttributeAclModule fires.
Option 2
Move the code that sets the values into the Application_BeginRequest event as described here.
Option 3
Create a custom implementation of RequestCacheableSiteMapNode that doesn't override the Url property and a custom SiteMapNodeFactory to provide instances of your new class, then inject them both with DI.
Option 4
Remove the request cache value for the Url property manually, so it can be regenerated the next time the Url property is accessed.
var parentNode = siteMapNode.ParentNode;
parentNode.Title = entity.Parent.Title;
parentNode.RouteValues["id"] = entity.Parent.Id;
var urlRequestCacheKey = "__MVCSITEMAPNODE_" + parentNode.SiteMap.CacheKey + "_" + parentNode.Key + "_Url_True_";
this.HttpContext.Items.Remove(urlRequestCacheKey);
i have the following code:
FileInputStream fis =
new FileInputStream("C:/test.pdf");
//PrintJob.Builder test = new PrintJob.Builder(fis);
//test.duplex(true);
//test.build();
Map <String,String> newMap = new HashMap<String, String>();
newMap.put("job-attributes", "sides:keyword:two-sided-short-edge#copies:2");
PrintJob pj = new PrintJob.Builder(fis).jobName("testJob").copies(2).attributes(newMap).build();
cp.print(pj);
The issues i have is even though i have set copies to (2) it only prints it out once....
anything i have done wrong?
copies:2 in the job-attributes is incorrect. You need to code:
copies:integer:2
Somehow, the incorrect job-attributes entry causes the...
.copies(2)
..on the Builder to be ignored.
I was able to reproduce that on my system using the older(!) de.spqr-info cups4j v1.1 from 2016 (not the current v0.7.6 org.cups4j).
But beware: if the job-attributes value is correct, the value from the Builder will be used (even if you didn't specify it! It defaults in that case to 1)
The only way to use the value from the job-attributes is to explicitly code .copies(n) (where n <= 0) on the Builder.
I have written an Outlook plugin that basically allows emails being received through Outlook to be linked with a website so that the email can also be view in the communications feature of the website. I store additional details within the ItemProperties of a MailItem, these details are basically things like the id of the user the email relates to within a website.
The problem I'm having is any ItemProperties I add to a MailItem are being printed when the email is printed. Does anyone know how to exclude custom ItemProperties when printing an email?
Here is the code that is creating the custom ItemProperty:
// Try and access the required property.
Microsoft.Office.Interop.Outlook.ItemProperty property = mailItem.ItemProperties[name];
// Required property doesnt exist so we'll create it on the fly.
if (property == null) property = mailItem.ItemProperties.Add(name, Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText);
// Set the value.
property.Value = value;
I'm working on Outlook extension and sometimes ago we had the same issue.
One of our team members found a solution. You can create some method which is responsible for disable printing. You can see peace of our code below:
public void DisablePrint()
{
long printablePropertyFlag = 0x4; // PDO_PRINT_SAVEAS
string printablePropertyCode = "[DispID=107]";
Type customPropertyType = _customProperty.GetType();
// Get current flags.
object rawFlags = customPropertyType.InvokeMember(printablePropertyCode , BindingFlags.GetProperty, null, _customProperty, null);
long flags = long.Parse(rawFlags.ToString());
// Remove printable flag.
flags &= ~printablePropertyFlag;
object[] newParameters = new object[] { flags };
// Set current flags.
customPropertyType.InvokeMember(printablePropertyCode, BindingFlags.SetProperty, null, _customProperty, newParameters);
}
Make sure that _customProperty it is your property which you created by the following code: mailItem.ItemProperties.Add(name,Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText);
On the low (Extended MAPI) level, each user property definition has a flag that determines whether it is printable (namely, PDO_PRINT_SAVEAS). That flag however is not exposed through the Outlook Object Model.
You can either parse the user properties blob and manually set that flag (user properties blob format is documented, and you can see it in OutlookSpy (I am its author) if you click the IMessage button) or you can use Redemption (I am also its author) and its RDOUserProperty.Printable property.
The following script (VB) will reset the printable property for all user propeties of the currently selected message:
set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
set Msg = Session.GetMessageFromID(Application.ActiveExplorer.Selection(1).EntryID)
for each prop in Msg.UserProperties
Debug.Print prop.Name
prop.Printable = false
next
Msg.Save
Given stage coordinates (x,y), I want to make my flash app behave just as if the user clicked at position (x,y). That is, something like
function simulateClick(x:Number, y:Number):void{
var e:MouseEvent = new MouseEvent(MouseEvent.CLICK, true, false, x, y)
stage.dispatchEvent(e);
}
I've found a bunch of pages talking about this kind of thing, and they all give solutions similar to the above. However, this isn't equivalent to the user clicking at (x,y). There are two problems:
The first is that e.stageX and e.stageY are both 0. I can't set them directly. The documentation says they are calculated when e.localX and e.localY are set, but this isn't happening when I set e.localX before dispatchEvent, nor in the event listener.
I could rewrite all of my event listeners with something like this:
var p:Point = e.target.localToGlobal(new Point(e.localX, e.localY));
Is this the only option?
The second problem is that my event listeners are registered with children of stage, not stage itself. So I need to find out what target to call dispatchEvent on. Clearly Flash is capable of determining what the target should be, ie which object owns the topmost pixel visible at position (x,y), because it does so when the user actually clicks. Is there an easy way to get at this information, or should I just write my own recursive function to do the same thing? I'm using DisplayObjectContainer.getObjectsUnderPoint at the moment, but it's not quite right.
I'm writing in FlashDevelop, if that makes any difference.
e.stageX/Y is populated correctly for me... also getObjectsUnderPoint() seems to work fine. I'm assuming that the x/y values passed to simulateClick are global coordinates?
edit: as pointed out in the comments, the mouse event must be dispatched on InteractiveObject instances... modified the code accordingly.
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.DisplayObject;
import flash.display.InteractiveObject;
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.geom.Point;
public function simulateClick(x:Number, y:Number):void
{
var objects:Array = stage.getObjectsUnderPoint(new Point(x, y));
var target:DisplayObject;
while(target = objects.pop())
{
if(target is InteractiveObject)
{
break;
}
}
if(target !== null)
{
var local:Point = target.globalToLocal(new Point(x, y));
var e:MouseEvent = new MouseEvent(MouseEvent.CLICK, true, false, local.x, local.y);
target.dispatchEvent(e);
}
}
public function addedToStage():void
{
var parent:Sprite = new Sprite();
stage.addChild(parent);
var child:Sprite = new Sprite();
child.name = 'child 1';
child.graphics.beginFill(0xff0000, 1);
child.graphics.drawRect(0, 0, 200, 200);
child.graphics.endFill();
var child2:Sprite = new Sprite();
child2.name = 'child 2';
child2.graphics.beginFill(0xff00ff, 1);
child2.graphics.drawRect(0, 0, 100, 100);
child2.graphics.endFill();
child2.x = 150;
child2.y = 150;
var bmpData:BitmapData = new BitmapData(80, 80, false, 0x00ff00);
var bmp:Bitmap = new Bitmap(bmpData);
bmp.name = 'bitmap';
child2.addChild(bmp);
parent.addChild(child);
parent.addChild(child2);
child2.addEventListener(MouseEvent.CLICK, function(e:MouseEvent):void
{
trace('target: ' + e.target.name);
trace('localX: ' + e.localX);
trace('localY: ' + e.localY);
trace('stageX: ' + e.stageX);
trace('stageY: ' + e.stageY);
});
simulateClick(190, 190);
}
Output:
target: child 2
localX: 40
localY: 40
stageX: 190
stageY: 190
For question 1: After you create the MouseEvent (assigning it a local x,y) you should be able to directly reference e.stageX and set it to what you want prior to dispatching the event. It's just a property of the MouseEvent instance.
For #2, currentTarget is always the thing that is topmost under the mouse, while target is the thing that is dispatching the event -- assuming the event is genuinely being dispatched by mouse interaction. In your case, you can set the target to be whatever object you have dispatching the event, and set the currentTarget arbitrarily. The question really is whether this is the most efficient way to deal with what's under the mouse right now; and the answer is, probably not. You'd be a lot better off using a MOUSE_OVER event to keep tabs on what the mouse is over right now, store that as a variable you can use when you want to call this, and don't try to iterate the whole display chain all the time (because Flash natively does that much faster than you can do it in a loop). If you put a mouseOver on the stage, and just check the currentTarget, you'll be getting whatever the topmost item is under the mouse on every frame where it changes.
You should be aware that (to prevent some obvious nasty scripts), certain actions cannot be triggered by mouse events that are generated dynamically by actionscript. These include opening a file reference and going fullscreen.
I have faced this issue too, gave me a bit of a headache.
In my situation I was creating the event, performing a bit of complex computations, but I couldn't retrieve global coordinates even though I had already set local coordinates.
Actually the solution was quite obvious in my case...
Global coordinates are populated only AFTER the event is dispatched, otherwise how can the event know how to translate local to global?
This is another pitfall, on top of not checking for the object used to dispatch event being an InteractiveObject.
I post this because someone else may face this issue due to both pitfalls. A quick answer easy to read.
