Use Condition Option In Program?

VS 2010 Best Option To Receive Emails In A VB Program
May 28, 2010I've seen that there are several options out there for being able to send email from within a Visual Basic program, but I've seen much less written about how to use the program to receive emails. What I'd like to do is set up a dedicated email account (probably g-mail or Yahoo or something similar, although it could be through the email package that comes with my web hosting) that I'd use to send short text commands to the program from my laptop or smart phone. Periodically the program would download new emails (if any), and parse the body to see what I'm telling it to do. Something like, "cmd a" tells it to e-mail me Report A, "cmd b" tells it to e-mail me Report B, etc.

Turning Off Option Strict - Whether Our Program Is Running On A LAN Or The Internet
Aug 3, 2010Late binding is not allowed and that's how we want it. Depending on whether our program is running on a LAN or the Internet, we need to dim an object as one of two types. We use an if...then statement to ascertain whether or not we are running on a LAN or the Internet.
When we declare our object inside the if...then statement, we have declared in the wrong scope and cannot use the object. When we declare it as an 'Object' type and use DirectCast inside an if...then statement, we receive a late binding error. How can we get around this problem without turning off Option Strict?
VB Program Change The Computer's Regional And Language Option?
Dec 2, 2011I do not live in USA, and my program run specifically with my country's Regional and Language Option format. However, many Windows XP, Vista and 7 installed in my client computers automatically with English (United States) Regional and Language option. I want my program to automatically change the computer regional and language option to my country. However, I do not find anyway to do that (changing the computer regional and language option in runtime by the program), yet.

View 4 RepliesScript - Program To Where When Click An Option, A Text Outputs For Each Button Clicked
Feb 12, 2011I'm trying to do is make a program to where when you click an option, a text outputs for each button clicked, the general design looks like this:
That's just a beginning, since the whole rest of the thing will be the same concept pretty much, and what I want to have it do is, like stated earlier, once the option is chosen, a text output, like this:
I know there is an alternative to solving that, but it will take me 10x more time, and that is, creating a new textbox, setting the visibility to False, and typing what I want outputted in that text box, then putting: RichTextBox1 = TextBox1.Text
I know that works, and gives me my output, but I just wanted to know if there was any other way but that.
2003 - Program Running Under Alternate Credentials - Option To Open A UNC Path To A Network Share
Sep 8, 2010I have a program written in VB.net 2003 that are folks run under alternate credentials. Inside the app there is an option to open a UNC path to a network share. We were running Windows XP SP3 and IE6. The code is simple just a call to the explorer.exe with /root,\UNCPath. After installing IE 8 onto the machine this no longer works. Best I can tell the code is still working but now being executed in non interactive mode so nothing opens up. You can however see a new spawned explorer.exe running under the system account for each attempt at opening a UNC Path. Any ideas what IE8 could have done to cause this behavior?

Completely Unload A Form?
Sep 25, 2006I have a form that I use to get the user to input such as a username and password in order to make a network connection. This connection can be disconnected and reconnected as many times as neccessary whilst the application continues to run.
I obviously, therefore, need the form's text boxes, combo boxes etc to reset to their blank versions every time that the form is shown.
In VB6 this was easy; you just unload the form which completely removed the form from memory and thus the next time you showed it it was reset to it's blank state. In VB 2005, however, there is no unload so we have to use Close. I have done this and assumed that it would function in the same was that unload did in VB6.
The problem is that when I close the form using the form.close event handler the form disappears perfectly but when the form.show/showdialog is used the old form data still remains telling me that the form hasn't actually been unloaded but rather appears to have just been hidden.

Hide A Button Or Unload It?
Nov 30, 2010I have a button that I am trying to only allow specific people to see. So I need to unload it or hide it if they aren't the correct person or have the requirements. When I try to use btnUpdate.hide() in my else it will first allow someone to click on the button and use it then it will hide it. It's not hiding the button right away. Thats what lead me to think that maybe i am suppose to unload it some how if its not the correct user or users.
How do i unload a button if its not the correct users.

Specifically Load Or Unload A DLL?
Feb 26, 2010I am calling a Fortran DLL from Vb.Net. I am declaring this in the class and then I am calling the DLL. I made this Fortran DLL from a Fortran Exe code. If I just use the exe code of the Fortran program I get different values than if I use Fortran DLL. First I thought may be there is a delay, so I used Sleep() before the end of the loop. But this does not change the values I am getting. I don;t understand why the results are different in exe and DLL, since I made DLL using the same exe code. I am not sure if the DLL is completely exited before it called again. Below is the code (partial).

Load / Use And Unload An Assembly At Runtime
Dec 1, 2011I am working on a project where I have to load assemblies (lets call them tasks) at runtime, run the task and then be able to kill off the whole assembly so that the dll can be replaced without interrupting the main application.There are many of these tasks running within the main application,some run sequentially and some run in parallel.Occasionally one or to of these tasks need to be updated and then re-added to the queue. Currently we are stopping the entire application and interrupting the other tasks at whatever stage they are at, which is not ideal.I have figured out that I will have to load each assembly into a separate AppDomain, but loading the assemblies in those domains is proving difficult, especially when I need to actually run the tasks and receive events from them.I have been looking into this problem for a couple of days and have still not managed to get a working proof-of-concept.
I have an Interface for the tasks which includes a 'run' and 'kill' method (subs) and a 'taskstep','complete' and 'killed' event.'taskstep' returns an object to be cached later, 'complete' fires when the whole task is done and 'killed' fires when it is ready to be unloaded.There should also be a timeout on the whole process of two hours and a timeout of 2 minutes on the killed event in case it gets stuck, at which point I would like to be able to unload it, forcing any threads to terminate (which is what 'kill' should do anyway).Each assembly may contain several tasks, all of which should loadable be unloadable.I have no problems loading these tasks as 'plugins' but am lost when trying to both use them and unload them. If I have to create some elaborate wrapper then so be it but is what I need even possible? I have tried inheriting from MarshalByRefObject but I do not even know the assembly fullname unless I load it first, which then locks the file. I have tried loading from a byte array of the assembly. This means that the file is not locked but a copy of it remains in the current appdomain. This will become problematic over the following months / years![code]
AppDomain.Unload Does Not Free Up The Used Memory
Oct 23, 2011I'm kinda new here, and I didn't know what forum to put this in, so I just put it here. I wanted to load an assembly to an Application Domain, use it, then unload it when I'm done with it. The assembly uses too much memory. The problem is: After I unloaded the assembly, the memory used is not getting freed. I was watching the performance all the time. The available memory increases only after I close the whole application. And that assembly is the only thing that uses a lot of memory in my application. Here's the code I used to load and unload the assembly: How can I free up the memory without closing my application. The memory was suppose to get freed up by simply unloading the assembly that uses it much.
View 2 RepliesLoad/Unload Windows Drivers?
Jun 23, 2010Followup to a previous post: It's been determined that Windows Device Drivers cannot be written in VB.NET; that's being dealt with separately.
What I'm interested to know here is if there's a DotNET Framework facility for adding/removing/managing device drivers; for example, can I build a VB.NET application to list loaded drivers, or drivers attached to a specific device, then load or unload those drivers as needed? It never hurts to try. In a worst case scenario, you'll learn from it.
