Script To Set ShellReadyEvent For Forced Shell
Sep 2, 2009
I'm having a really hard time with this. I have a situation where I'm running an "internet kiosk" kind of situation. So i'm forcing firefox to run as a shell with some custom settings that prevent users from tampering with anything. Problem is, and this is well documented, you force windows to use something thats not explorer.exe as the shell - you get to wait 2 min before the welcome screen dies. I'm running XP Home - I've tried disabling the Welcome screen in the registry but, nothing seems to work. I keep running across snippets of code refering to something like this:[code]
I've used C++ a few times, so I sorta kinda get whats going on, but I have no idea how to implement it. A lot of people are talking about just adding these snippets to the beginning of their custom shell applications. My shell *is* an application, so i can't add any code. I need to know how to send this signal to the kernal so i can shorten my boot time. I'm assuming I need to take some VB code and turn it into an EXE so i can run it at boot - I tried SHELLing this out to cscript.exe in a batch file, but it says theres errors.

I'm going to attempt to make a shell replacement for the Windows default shell: explorer.exe. I'm not sure if its possible using Vb.Net, but I can't seem why not. My end goal is to use a custom made shell for a Windows Preinstallation Environment instead of the default command prompt. I plan to use a 3rd party program to compile the program with the .NET Framework. Otherwise, it wouldn't work because Windows PE does not support the .NET Framework.

In my Tools/Options box under Projects and Solutions/Build and Run, I have selected: Before building: to "Don't save any Changes."However, after making changes to a form, I would like to run it without saving, but I get a message that forces me to save, unless it runs the version of the program before the changes were made.The VB 2005 edition works the way I want it to allow testing without saving, but VB2008 does not allow this.Is there any way I can change this behavior?

I have a project im working on in which data is loaded from a database using sqlite into a datagridview, one column in this datagridview is a custom rating column which windowsmedia like rating stars are displayed and when moused over the image is changed using the following custom column. When the mouse is moved in a cell the cell is forced to repaint and display the star image according to the mouse location in the cell.Now the odd thing is that this works perfectly when the data is loaded in with the SQLreader and added row by row, but when the data is loaded in using fill() using a datatable the cell will not repaint when moused over unless its row is currently selected or has been selected. Everything works fine loading the data row by row but loading time is much longer when there are 1000 items in a table.[code]

I have a web service with both SOAP and REST endpoints. I have to accept requests from a client that I do not have any control over on my REST endpoint. Currently the client gets a 400 response and the tracelog on my server shows this error:
The incoming message has an unexpected message format 'Raw'.
The expected message formats for the operation are 'Xml', 'Json'.
I've tried everything I can think of with the WebContentTypeMapper but seem to end up right where I started every time. The request from the client doesn't appear to be well formed XML or JSON so if I try to force XML or JSON types from the WebContentTypeMapper I end up with parser errors.
So I guess I need to find out if I can force this endpoint to accept the message anyway.

After debugging a particularly tricky issue in VB.NET involving the order in which instance variables are initialized, I discovered that there is a breaking discrepancy between the behavior that I expected from C# and the actual behavior in VB.NET.Nota bene: This question concerns a slight discrepancy in the behaviors of VB.NET and C#. If you're a language bigot that is unable to provide an answer other than "that's why you should use C#, noob", there is nothing for you to see here; kindly move along.Specifically, I expected the behavior outlined by the C# Language Specification (emphasis added):
When an instance constructor has no constructor initializer, or it has a constructor initializer of the form base(...), that constructor implicitly performs the initializations specified by the variable-initializers of the instance fields declared in its class. This corresponds to a sequence of assignments that are executed immediately upon entry to the constructor and before the implicit invocation of the direct base class constructor. The variable initializers are executed in the textual order in which they appear in the class declaration.
Contrast that with the portion of the VB.NET Language Specification concerning Instance Constructors, which says (emphasis added): When a constructor's first statement is of the form MyBase.New(...), the constructor implicitly performs the initializations specified by the variable initializers of the instance variables declared in the type. This corresponds to a sequence of assignments that are executed immediately after invoking the direct base type constructor. Such ordering ensures that all base instance variables are initialized by their variable initializers before any statements that have access to the instance are executed.
The discrepancy here is immediately obvious. C# initializes class-level variables before calling the base constructor. VB.NET does exactly the reverse, apparently preferring to call the base constructor before setting the values of instance fields.If you want to see some code, this related question provides a more concrete example of the divergent behavior. Unfortunately, it does not provide any hints as to how one might coerce VB.NET into following the model established by C#.
I'm less interested in why the designers of the two languages chose such divergent approaches than I am in possible workarounds for the problem. Ultimately, my question is as follows: Is there any way that I can write or structure my code in VB.NET to force instance variables to be initialized before the base type's constructor is called, as is the standard behavior in C#?

I have an update app, which can be updated itself by another update app (so, the second app is an updater of the main updater). Both apps must have administrator permissions because of writing in the Program Files folder. Is it possible that when the main updater is running (under administrator rights) it can use Shell() to let the second updater run with administrator rights without a UAC confirm dialog popping up again?

I wrote a backup utility that synchronizes a list of folders. Errors appear in a list. In the list I can right-click to retry, exclude the folder next time, or open the folder in explorer to examine.When I shell to explorer I get an AccessViolationException. Form1 opens Form4 with Form4. ShowDialog(), and that's where the error occurs. The error does not occur within Form4 where the shell function is called. memory must be getting trashed somehow.I've used two methods, Shell and System.Diagnostics.Process.Start. Each produces similar results. Shell waits awhile before causing the error, but Process.Start causes the error immediately.This is VB.Net 2010 using framework 4, though I did resolve a shell problem once before with VBA by writing out a VBScript file then shelling to the VBScript file.

set the Icon for an item in a shell handler? I've set a contextmenu handler to the extension .savdata and added the text "Open with ConvertFile" to the handler so that the context menu for .savdata looks like this:
Open with ConvertFile

So how can I use "my.computer.registry.HKEY_CLASSES_ROOT" in VB 2008 express edition to add an Icon file path to the left of the context menu handler?

Apparently, it's not safe to use the .Net framework < 4 to write a shell extension.
As my users are likely to not have that version of the framework, I'd rather use a third-party solution so I can write the main app in .Net 2 or 3.
Can someone recommend an add-on for this, either open-source or affordable?

I have a VB.net program in which I call the Shell function. I would like to get the text output that is produced from this code in a file. However, this is not the return value of the executed code so I don't really know how to.
This program is a service but has access to the disk no problem as I already log other information. The whole service have multiple thread so I must also make sure that when the file is written it's not already accessed.

I need to be able to read a variable that is coming from the dos shell "sort of". We run this app that is supposed to create a word document.In some of the old school versions of word you could pass a command line parameter of /N to winwordto autocreate the file. That doesn't work in 2007 so I'm trying to write a vbscript to take it's place. I did the same in powershell and had not problems, it just recognized the variable.
