View 1 RepliesRelease Inner Objects Of A COM Interop Object?
Jul 12, 2010I have a managed class that uses a COM that looks like this.
[Code]....
Since I am using an unmanaged dll through a COM-Interob dll I am wondering if I need free the innerobj manually or if the gc is smart enough to do it automagically if I call ReleaseObject() My class implements IDisposable and I do the following atm: Runtime.InteropServices.Marshal.ReleaseComObject(myobj) Do I need to take care of releasing all inner objects that are created by the COM Object or not? And If I do have to do it, does the order matter (first inner then parent vs parent then inner)?

View 3 RepliesC# - Release "ownership" Of COM Object In .NET?
May 2, 2012I have a customer/partner who's trying to link their application with ours using our exposed COM functionality. So far, they've got a COM object which represents an instance of our software package and then use our COM methods to programmatically build something up for the user based on what they've done in their application. It's essentially an "export" feature.
What they've asked me to do, which I can't work out how to do is to allow the user to decide when the instance is closed. What I mean by this is when our software package is loaded up, it's viewable and is interacted with by the user. When they are finished they'd naturally click the cross at the top right to exit the software. This doesn't work as the COM object is still "active" in their application. Our software package can only be closed by killing the process in task manager whilst the application that loaded it via COM remains open. Once their application exits, ours will automatically close. It seems as if their application "owns" ours because of the COM call.
I've made a quick demo app in C# to try using things like Marshal.FinalReleaseComObject(myObject) to no avail.
Flattening An Object Hierarchy Using A Shim Class - Initializing Derived Object Properties From The Base Object?
Jul 10, 2010I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
'Release' My First Application?
Jun 18, 2010What is the 'proper way' of giving my application to people?
Ideally I just want to zip up the minimal amount of files and for people to put this in a folder of their choice and just run it.
I've noticed from playing with a "Publish" I end up with a "setup.exe" and also a "Application Files" folder.
Within that folder are the necessary files (a DLL and a .EXE) to run my application. Can I just supply those two files out to people?

Oracle 10g To 11g Release 2
Apr 21, 2010Currently we are using the Microsoft data access library Writen with a Oracle data provider for the framework 1.1. My customer has mandated that we upgrade from Oracle 10G to 11G release 2. 11G requires the .net framework 2.0 Is there a way to use the new Oracle data provider 11g release 2 with the older frame work. I have looked at/attempted changing the policy for oracle in the Windows assembly but my understanding is because its a third party DLL, I cannot.
View 4 RepliesRelease All The Memory?
Oct 1, 2010in main form, when a button is clicked, it opens a new form which has a webbrowser. users can use it to browser some sites. if the user closed this form, it goes back to the main form. and they can click button to open the browser form again.
I noticed that one thing. if the browser form is opened, it uses much memory (which is normal because of the site it browses). however, after the browser form is closed, the memory is not released.
In the browser form, when it is closing, the webbrowser is disposed and dereferenced. and no other part uses much memory in the form. GC is called too. what else should I do to release all memory the browser form uses?
now, it is like once the browser form is opened once, the memory usage never goes down even the form is closed.
.net - Release DC Before Or After Graphics.Dispose?
Jun 1, 2012On the back of a Windows Form, I get a window DC, create a Graphics object with Graphics.FromHdc, and then dispose the Graphics object before releasing the DC.
Private Declare Function GetWindowDC Lib "user32.dll" (ByVal hwnd As IntPtr) As IntPtr
Private Declare Function ReleaseDC Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal hdc As IntPtr) As Integer
Dim hdc As IntPtr = GetWindowDC(Me.Handle)
[code]....
Why did they do it this way?Should the DC be released before or after Graphics.Dispose?It is possible that the wrong order can cause resource leaks or memory corruption?

View 7 RepliesCan't Delete My Release File?
Mar 31, 2009I made a .exe file of my project (in vb2008 express ed.) and it was all working and then I copied the release file out of my project and an error came up (something about UNC share) and i realized the path was wrong, so when I tried to delete the Release file (currently on my desktop) a pop up message says you need to be administrator to delete this file so I press continue (as I am the administrator) and another message comes up saying "You need permission to do this" "Try Again?", when I click "Try Again" the same message comes up. I know this isn't directly involved with VB, which leads me to my second issue:
How can I create a file that is external from VB yet it still works? In my code there is a path that connects it to SQL is it perhaps something to do with that?

Mar 9, 2009I have a system that scans in images to multi page tiff files and allows the user to preview before finalising. When the user previews,they click on the page number which should then use the TiffBitmapDecoder to read that particular frame in from the Tiff file and display the BitmapSource in an Image control...this works just fine. The problem comes in when they scan another page which is then inserted into the tiff file. The tiff file is returning that it cannot be accessed as another process is using it. How do I get the TiffBitmapDecoder to release the Tiff file?

VB: Release A Device That Already In Use [ManagementObjectSearcher]?
Jun 12, 2011I am currently working on an application for use with scanning an printing devices. I use the ManagementObjectSearcher in order to retrieve device names and Id's:For example using (Don't forget to add the reference to System.Management.dll in the framework 2.** folder if you're trying the code)
Dim searcher As New ManagementObjectSearcher("Select * from Win32_PnPEntity")
Dim PnpDevice As ManagementObject
For Each PnpDevice In searcher.Get()
[code]....
There are various classes such as:
-CIM_LogicalDevice
-Win32_PnPEntity
Allow access to various properties-- most of which are read only.
Question: Is it possible through one of these classes to reset a scanning device that is already in use or check on its current status.
-CIM_LogicalDevice("Status")--Win32_PnPEntity("Status") return the value of "OK" when the scanner is in use by another application. So that property must not be what I'm looking for.
I just want to query the device and if it is in use (from a failed attempt or human error) reset the device. The object that calls the scanner/printer is waiting for an event handler(successful scan) that sometimes does not occur and I cannot dispose of the object locking the device up as "in use."
How do I free the device? Or would the solution be to create a timer which waits for the event handler which could contain a property flag set to true if it occurs. If the event doesn't occur in a given timeframe and the flag is false dispose the object?
