Restricted Textbox Code (Specifically, Building A Class Library With Code)?
Jan 2, 2012
I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.
Option Strict On
Imports System.ComponentModel
Public Class RestrictedTextBox

I'm working on a legacy vb.net application that does most of its work using inline code ( Within that script I need to access functions from a third party .net dll. The dll(s) themself are stored in the GAC. Before I started the page looked something like the following

I have some code that queries all the printers on our print server and returns a list. I need this code to work so please don't reply with comments asking why I am using it when you can simply type \Server to list the printers (I know this, but need the code to work as part of a larger application). When running the following code on an IT PC with admin rights, it works. When running on a restricted user PC, it doesn't. How can I add permissions in code to elevate the EXE to 'run as administrator'? [Code]

I've created a custom class that I've grown rather dependent on in my coding. I've encapsulated it as it's own "Solution" and use a reference to the class module within the solution on most of my new projects, and that all works fine. It seems slightly clunky to me that my encapsulated class module is packaged with solution-related directories and so forth. For me, this seems to make management and maintenance of these little class modules difficult (renaming them for instance). So now, a few questions:
When you recognize you have a useful class embedded within a solution:
1) What's your method for encapsulation? (is there a template you like?)
2) How do you organize/arrange your code libraries?
3) When, if ever, might you consider using that "Code Snippets Manager" thing in the IDE?
I'm struggling a bit trying to understanding how Visual Studio wraps-up everything in what appears to be a "Solution" umbrella. There doesn't seem to be a lot of write-ups on how to go about organizing your code libraries to work well within this Solution/Project Visual Studio framework.

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one! Am I doing something wrong?[code]

Are there any tools available for automatically formatting vb.net code - specifically for adding line breaks at a predefined line length? I'm working with a lot of code with long lines (thousands of lines), and manually reformatting it is quite time consuming. I've seen a number of tools for rearranging code into regions etc., but haven't found any that reformat with line breaks.

I've been working on a project the last couple of day with the help of a lot of you out there. I've more or less finished the design of the interfase, but there are stange this happening with the form. I can say much about what is wrong because I dont understand it, but I would like to. I have added the form Class code and the Designer Code, is that enough or is more required? Theres a msgbox that popup in the form Load event which I placed there to see what I could learn about the GraphicsBuffer.

I am using a .Net JavaScript implementation called Jurassic to run user-controlled scripts within my .Net 4 WPF application coded in VB.Net - C# answers are fine. The script engine runs on its own thread and provides an API for the script to interact with my application. This all works really nicely until a user executes a script that causes an infinite loop and takes out a core of the processor.
[Code]...
The reason I care about keeping the thread alive is because the user who wrote the script and the user who is running it may not be the same, and I want to keep the experience as smooth as possible the the user running the thread. There also might be legitimate situations in which a single JavaScript function would run for a long time and I do not want to kill that, I just want to stop being allowed to hog the resources.
Solutions that involve stopping the thread from slowing down the system but that still show high CPU usage are not preferable because I do not want the user to wrongly feel that the application is resource intensive.

Between testing sessions on my windows service, I'm changing code (little tweaks here and there). For more detailed debugging, I've had the application send messages to a text file everytime it does something (executes a new procedure, catches an exception, etc).
I've been doing this for a while, but ever since yesterday, it appeared that the new code wasn't being used. To test this, I changed the name and location of the log file that the service would use, and re-installed it shortly after a new successful build. As it turns out, the service is writing only 1 message (about a timer being started - which is only supposed to happen after it's logged the start of the service) to the old text file. It looks to me like my service isn't using the new code in my Service1.vb file, Like the old code has been cached or something, and the service is installing from that.

I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.
Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")
End Sub
[code]....
This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim IB As String
IB = Session("IB")

I've been reading on XML Serialization and wanted to take a break for a bit and was cruising the code library and started playing with Mike Rosenblum's code in this thread post#2[URL].. When I loaded the code into a test project, I received this error before it was run. Function 'IsAlreadyRunning' doesn't return a value on all code paths. Are you missing a 'Return' statement?

I am trying to retrieve the Attributes of a class's property specifically. So for example. Let's say I have a class called "Employee", and a custom attribute called CustomLabelAttribute with a string value. What would I need to do to retrieve the value of CustomLabelAttribute for Employee.FirstName specifically? I assume I will need to use reflection, but it's kind of new to me, and I've just recently started using it on any level.

I put my standard About Box and Splash Screen into a code library along with a number of other stadard things I use. The about box works fine in that I can instantiate a local version and then show.
My question is how can I select the splash screen out of the dll? The drop down box on the Properties page only shows forms in this project.
In C# I can instantiate the splash screen manually before the intialization process and then hide afterword. Is there a similar way in VB?

When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.

I'm trying to familiarize myself with network programming, and what better place to start than designing an FTP client code library?So far I'm not doing very good. I'm trying to create a method which downloads a file from a remote server to a local file path. To do so, all the examples that I could find declare a byte array that serves as a data buffer. I completely understand the point of doing that, rather than reading and writing byte per byte, but I just can't get it to work. Whenever I set a buffer greater than 1 byte, the output is somehow corrupted (different checksums, media files won't play etc).[code]Because this code does work when I set the buffer size to 1, I feel like there's something going wrong with the byte order. But all of this code is synchronous, so how is that even possible.[code]

Is there any C#/VB.NET library that can produce HTML output from Python sourcecode ?
I mean display the Python sourcecode syntax-highlighted on a website ?
It should be C#/.NET code, not a JavaScript library. This is because I highlight many programming languages, and their HTML is already generated server-side, so I really can't use a JavaScript library.
