• Visual C# Problem with event...

  Hi ! Well... I do this to add a function on a event: dataRecebe.dadosRecebidos += new dataRecebe.delDadosRecebidos(atualiza_ligado); and this to take off.. dataRecebe.dadosRecebidos -= new dataRecebe.delDadosRecebidos(atualiza_ligado); Correct ! But if I add many function for determinate event... I will always do "... -= ..." don't have another way Hug, Joao Hi, the only way to remove an event is using the -= syntax. However if you define you own event i.e. event X { add{...} remove{...} } You can get access the the underlying delegate and then clear out all of the event listeners by resetting the delegate to null.

• Smart Device Development DataReceived/SerialPort Troubles

  I am building code for the PocketPC to interface with a chemical sensor to poll and report on chemical agents in the air. I am having a devil of a time getting the DataReceived event to pass content (through an Invoke) to the main thread. When I write an "N" to the device, it is supposed to send back the following string to the UI, which represents the chemical sensor types that are housed in the unit: "CO VOC H2S LEL OXY" When I send an "R" to the device, it is supposed to send the current readings for each of the sensors as a string that looks like this: "00000 00000 00000 00000 00207". I have all of this working successfully as a WIN32 application, but it doesn't port cleanly to the .NET 2 ...Show All

• Windows Live Developer Forums GetRoute w/ Custom Disambiguation Dialog not working

  I was wondering if there is a way to show a custom Disambiguation Dialog when using GetRoute or if I'm stuck with the default.

The call map.GetRoute(fromAddress, toLocation, null, null, onGotRoute); fromAddress is a string, toLocation is a LatLong is there a way to use one of the 'Find' methods to get the from location without the method changing the current map ...Show All

• Visual C++ Generate sequently events?

  Hi all! How can I generate a sequently event (I'm thinking about some kind of OnTimerInterrup() etc. that will happen in every 5 seconds..) I need to do it for calling a function to test if there was a message or not. Thx! You may use CEvent from MFC. I would also like to add that you'll have to be familiar with Multithreading for that. ...Show All

• Windows Forms Form that never loses focus

  I have created a form with SetTopmost set, and shown it with dlg.ShowDialog(), but I really need it to keep the focus EVEN if the user clicks on another application. Has anyone got a bit of windows magic that means that my dialog box keeps the focus whatever happens, until I dismiss it in code (with dlg.Close() or whatever). I've tried catching the 'Deactivate' event and so on, but that doesn't seem to solve the problem. Thanks for any clues or thoughts..... Yuck, you are trying to do something that Windows makes, quite intentionally, very hard to do. Your best bet is trying to enumerate the windows with the EnumWindows() API function and calling EnableWindow() to disable/enable them. You'll find ...Show All

• Software Development for Windows Vista Property binding and activity inheritance

  Hi all, I created base activity ("A1") with 1 property "Item" of MyType kind. I created another activity ("A2") that inherits from A1. Both classes reside in one assembly I created a workflow ("W1") with property "IncomingItem" of MyType kind, which resides in another assembly. Now, when I put A2 activity in the W1 and try to bind A2's "Item" property (the inherited one) to W1's "IncomingItem", I've got an error message that tells that types don't match. Any ideas what I did wrong I'm working with RC1. Everything worked fine on Beta2 version, but when I ported workflows to RC1, workflow designer doesn't accept it (although, code compiles ...Show All

• Microsoft ISV Community Center Forums Worksheet.Copy causes execution to stop

  Hi I am experiencing an odd behaviour from my VBA code in Excel. I have some code that has worked until recently.

In the line where i say Worksheet.Copy, the execution simply stops. No errors appears, nothing. <CODE> On Error GoTo ERROR: Worksheets(SN_MonthYearAct).Copy After:=Worksheets(Worksheet.Count) ....

  Besides removing this feature from Office during setup, is there a process to remove this virtual printer from 300 users with roaming profiles on an active directory network We are having an issue with this printer assuming the "default printer" selection for our users.
