.net - Dispose Of These Unmanged Resources Without Requiring A Reference To Each?
Jun 23, 2009
I have a class bMainframe that manages the connections to 4 different mainframes. It allows for the same underlying unmanaged library to be opened in specific ways and more than one mainframe to be connected to at a time. Each library has its own disposal code for the unmanaged mainframe connection resource. The wrapper also has code that calls the individual mainframe connection's disposal code.
This causes an error if someone's project does not make use of all 4 mainframes, but calls the disposal on the wrapper. (FileLoadException could not load assembly X of the 4 managed mainframes) Since that disposal code checks to see which of the 4 are not nothing/null. Even if nothing/null this is causing .net to try to load the assembly and crash.
Is the disposal code in the outer wrapper helpful or necessary? is there a way to check if the assembly for a type is even loaded that doesn't trigger.net to load the type/assembly?I modified the code below to block the fileloadexception, but I don't believe this is the best way.
Protected Overridable Sub Dispose(ByVal disposing As Boolean)
If Not Me.disposedValue Then
If disposing Then

I was wondering if you should dispose undisposed resources before closing your application. Maybe it's not necessary to do this because closing your application automatically takes care of this.

Look at this code:
CODE:
My question: When the sub ends the reference to the newReadWorker goes away since it is local to the routine but the worker still runs until it is done. Is the worker disposed of properly when it is done or should I handle the worker better. I am not getting any errors from this design. I just don't want to waste memory.

I have a dll which I call for compression. What I would like to do is reference this at runtime from my embedded resources instead of having the file somewhere on disk.

Lets assume that I code a DLL in .Net and I've added some items to the project (For example a picture, or an XML file that contains some kind of configuration for the DLL), and I set the "Copy to output directory" to be "Copy Always".
Now, what I wanted is that if I give my compiled DLL with the bunch of files that were added as items to it, then if someone ads a reference to the DLL in his project then on compile it will copy all files and not just the DLL.
Is it even possible (Some kind of configuration on Visual Studio maybe)?

I'm currently developing a compact program, but i need to use some .dll as references. Thats ok! But the problem is, i need the .dll reference together in the same directory as the program which i dont want to, since i need it to be compact, just on .exe.
Is there any way to load the .dll reference via the Resources or another way?

Why does everyone say in forums that it is Rolling back in the dispose? Where does it rollback?

I'm trying to save a setting that keeps what background image I'm currently using.If it's an external file, there is no problem, i can just get the .location and set it in a String setting to store it.
But, if I want to store an image resource as a setting, how do i do it?I know i can store rawdata, like bitmap information, but then i can't set that type of data to the my.background.
I don't know if the question should be: "how do i reference resources", but the my.resources.resource.methodsList doesnt contain anything that seems to be of use.

I'm making a project for school with a group of classmates. It is an application that needs to reference quite a few pictures and strings from My.Resources. I don't know what the problem is but, whenever I run the program, I get a message that reads this: "There were several build errors. Would you like to continue and run the last successful build?"
And then below in the Output:
----- Build started: Project: Wilkes-Barre Virtual Scavenger hunt, Configuration: Debug x86 ------
COM Reference 'WMPLib' is the interop assembly for ActiveX control 'AxWMPLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked.

I have a Main program form which launches a new Login form. I would like my application to require user to log in before he can manipulate with the Main form.
I create the Login form from code as a new LoginForm class. User can simply click on the Main form. So i would like to deny access to main form until the user loggs in.

I have made a login system for secure file storage. The way it works, is when you create an account it adds values to the registry containing the password and username. It needs to have administrator privileges to write those values, but not to read them. It would be very inconvenient to have to run as an admin every time, so I need to know how to require administrator privileges when the click the "Create Account" button, but not require admin rights when the program starts up.

I have a program, and there is a timer to run it every 15 minutes. Every time it run, it will create a new exe / thread, (I monitor this thru an external software called TCPView). With the thread growing, it may slow down the performance, is there a way to dispose the thread before a new one is created?

I am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:
frmB = New FormB()
frmB.Show()
From btn2 (frmB is already open) I bring frmB to the front from behind frmA:
FormB.Show()
FormB.BringToFront().
No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.
from btn1 (in frmA) I do this:
frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()
then from btn2 -- this is where I have the problem
FormB.Show()
FormB.BringToFront()
I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
