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?
View 1 RepliesThe "named pipe" seems rediculous to pass data between processes (exe's). Is it possible to run a single instance of a VB.NET Class Libary (dll) such that two programs can access the same memory resident dll, thereby passing data via functions and or subs?When I try to make the class library as single instance, the "Enable Application Framework" is greyed out, and thus the option to "Make Application Single Instance" is also greyed out.When I try to call the dll from two processes, I simply just create two instances, so storing data in a module doesn't work

Is it possible to make it so that the user using the Class Library has to declare a new Instance of MainClass() before using Subs/Functions in Class2 or Class3?
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.

Imports System.ComponentModel
Public Class RestrictedTextBox

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]
View 2 RepliesI'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter encountered a generic type instance in a signature. Generic code may not be exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.

I've createda vb.net class library where I've defined a number of small classes... nothing complicated, just working with strings, sending emails, etc.In another project, I reference the class library and I'm seemingly able to create an instance ofone of tclasses - intellisense shows me all of the plic properties, methods, etc... all looks perfect. No compile errors at all, nothing b gumdropsand lollipops.When I run the app I'm working on that references the class library, it fails at the point where I'm creating an instance of the class and gives me a vague exception, "System.TypeLoadException".

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?
Does anyone have a program that will find Visual Basic 2008 code and place it into an organized code library?
View 1 RepliesWhen 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.
View 3 RepliesI'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.

View 3 RepliesI'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]
View 1 RepliesIs 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.
I am trying to create a sort of code library in visual basic where the form displays a list box of certain project files in vb that i have made in the past and when clicked, launches the .exe files of those visual basic program project files.I know it does not work the same way as writing/ reading text files to vb and it seems as simple as 'on click, launch .exe of selected string "vb program 1" and so on.
