I am attempting to take a string and convert it into a code 128 barcode in vb.net. I am a novice programmer and was wondering what some people thought would be the best design practices for accomplishing this.
A simple google search has yielded a few seemingly free solutions to this.http://www.onbarcode.com/vb_net/code-128-generator.htmlfor example
I could also attempt to do this myself, but I'm not sure the exact method of converting strings into barcodes.I am going to keep looking into this but if someone knew this off the top of their head already it could save me some time.
Thanks in advance

If you don't want to write any code for string conversion in barcode and don't want to buy an external component, you can use the ItextSharp library ( http://sourceforge.net/projects/itextsharp/ ) which is in my opinion the simplest way to achieve your goal. You can find several resources online and on stackoverflow too for itextsharp, mostly in c# but also vb.net.
for barcode generation vb.net code you can have a look here:http://professionalaspnet.com/archive/2008/11/09/A-Quick-and-Dirty-Bar-Code-Image-httpHandler.aspx

Have a look at the following codeproject page - Barcode Image Generation Library
This allows you to generate a barcode image in your desired format from a string.
It should be enough to get you started

You need to question your goal. That answer will drive your methodology.
Your google link shows a product that displays sample code on that very page. What's wrong with that?
What is your target output? A report object, or will you print directly to the printer/label?

The printer named in the PrinterName property does not exist.
Examples
The following code example prints the file that is specified through the command line to the default printer.
Note
The example requires that each line fits within the page width.
Use the System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO, and System.Windows.Forms namespaces for this example.
Remarks
Specify the output to print by handling the PrintPage event and by using the Graphics included in the PrintPageEventArgs.
Use the PrinterSettings.PrinterName property to specify which printer should print the document.
The Print method prints the document without using a print dialog. Use a PrintDialog when you want to offer the user the ability to choose print settings.
Note
If an exception that is not handled by the Print method is thrown during printing, the printing of the document is aborted.

dBarcode.NET components provide the ideal way of creating barcodes in Visual Studio projects and include components and WinForm Controls for Visual Studio 2005 or later, for the .NET Framework v 2.0 or later. The discussion here focuses on Windows Forms projects, but the components may be used in any .NET or ASP.NET project. For users who prefer non-CLR components dLSoft has a range of DLLs and Active DLLs for use with C++.
Components are available for all major 1D and 2D barcode types and create high resolution images with full control over all barcode properties.
Since I use the Maschine, it's a completely different story. DUDE, gimme that thing, I'll give you an MPD lmaonah but on the real, back in the good ol' FL-days, I never really liked Slicex, I really liked the control through the Edison method (fun fact: the only reason I even tried playing around with Edison is because I didn't quite get the concept of Slicex). MPC 1000 as a controller? But I think Edison will give you the most control as it basically has the same controls you would have on a real sampler (trunicate, fades, normalizing, pitch shifting and even some more advanced features) for each individual chop, and the chopping workflow (if you do it the way I did it) is fast as fukk boiiiii, only real downside that comes to mind is that you have to do the whole chop again if you want to change something.but seriously, why don't you just use the 1k lol?. How to use slicex fl studio 12. Yeah, it's good because you can you can layer samples/chops easily, and change individual tune without going through something like that 'preview' window.
Screenshot Adding a dBarcode.NET product to the Visual Studio ToolBox
To add a dBarcode Component or Control to the Visual Studio ToolBox, display the ToolBox and select the Components tab. Right click on the Components pane and select Add/Remove Items. from the pop-up menu displayed. A dialog box is displayed listing the currently installed components. Ensure that the .NET Framework Components page is displayed.
Push the Browse button and navigate to the location where you have installed or copied your dBarcode.NET component and select the DLL (e.g. AbcnetLib.dll for the Component or dBarcode1D.dll for the Control).
Then push the Open button.
The list of installed components is now displayed, including your dBarcode.NET component or control. Ensure that the checkbox alongside the component name is checked. Now push the OK button.
Using the control to place barcodes in Visual Studio projectsAdding a dBarcode.NET Control to a Windows Form
With a project's form open in design mode drag the dBarcode.NET control icon from the toolbox onto the form.
The control appears on the form using default settings. The control may be positioned by dragging around the form, and multiple controls may appear on a single form. The first to be added will be called Barcc1d11, the second Barcc1d2, and so on; the names may be changed by the user by modifying the Name property within the Properties box.
Design-time menu Design time Properties dialog
The default properties for the control may be set by selecting the control, right-clicking on it and selecting 'Show barcode properties dialog' from the pop-up menu displayed. The values you provide here will be used as defaults unless properties are changed programmatically within your project.
The control is always displayed on the form (unless you turn its Visible property to false), so no additional code is required. The barcode content can now be changed programmatically by changing the Caption property, eg.
dBarcode1.Caption='0987654321'; C#
dBarcode1.Caption='0987654321' VB
The Barcode properties dialog may also be displayed at run-tim by calling the dBarcode1.doProps() function, and the barcode may be saved or copied to the clipboard with a specified graphics resolution using the following functions:
dBarcode1.copyBarcode(hres.vres); C#
dBarcode1.copyBarcode(hres.vres) VB
dBarcode1.saveBarcode(hres,vres,filename); C#
dBarcode1.saveBarcode(hres,vres,filename) VB
where the filename extension (.BMP, .EPS, .GIF, .JPG, .PNG, .TIF, .WMF) specifies the graphics type.
Using the Component to include barcodes in Visual Studio projects
If you prefer to use a component rather than the control to create barcodes in Visual Studio projects ..
Adding a dBarcode.NET component to a Visual project.
With a project's form open in design mode drag the dBarcode.NET component icon from the toolbox onto the form.
The component icon appears on the panel below the form – it does NOT appear on the form itself. The instance of the component will be given a default name (eg Abcnet1) which appears in the properties panel when the component is selected. A single Form may contain any number of dBarcode.NET Components. The first to be added will be called Abcnet1, the second Abcnet2, and so on; the names may be changed by the user by modifying the Name property within the Properties box.
The properties panel also displays all other settable properties for the component, and these values will be used as defaults unless properties are changed programmatically within your project.
Setting and retrieving property values programmatically
The dBarcode.NET Components may be operated entirely by setting or retrieving Property values programmatically.
Clicking on the dBarcode Component in the panel under the form when Visual Studio's Properties box is displayed will show the current settings for component's available properties. Most of these may be edited using the Properties box, or may have their values set from within the user's program by statements of the kind
Abcnet1.Caption='12345' in VB
abcnet1.Caption='12345'; in C#
dBarcode Component properties that are set AFTER a barcode has been created may be retrieved within user's programs by statements of the kind:
x=Abcnet1.Error in VB
x=abcnet1.Error; in C# Setting properties through the Barcode properties dialog box
Using the Method AbcProperties() causes the Barcode properties dialog to be displayed. This displays all settable properties in a convenient form and enables changes to be made by selecting from drop-down lists or entering values into edit boxes, or summoning standard Windows dialogs for the selection of colors or fonts.
Displaying a barcode on a form
To display a barcode on a form a PictureBox is used to hold the image.
Place a PictureBox Windows Forms control on the form and add some code to your program to take the barcode image from the dBarcode.NET component and use it as the Image for the PictureBox
For example:
Printing a barcode image
Printing the image returned by the Barcode() call may be accomplished by any of the printing techniques available for Visual Basic. However, probably the most useful approach is to use the DrawImage() method in a PrintPage handler as illustrated below, and in the examples provided with the components:
VB
C#
While the PageUnit setting can be any of the allowed values, we have found that the most accurately sized barcodes are produced when the highest resolution setting (Document, equivalent to 300 units per inch) is used.
Saving barcode images
Barcode images may be saved in any of the supported graphics formats (BMP, GIF, JPG, PNG, TIF or WMF) by using the sBarcode() method:
er = dbcnet1.sBarcode(hres, vres,fname)
where fname is the full path name (including extension the identifies the graphic type) of the file that will receive the image, and hres and vres are the pixel resolutions required for bitmap-type images. WMF images are saved as high resolution Windows metafiles. The returned er is 0 if the file is created successfully, or non-zero otherwise.
Barcode images may also be saved to streams using
er = dbcnet1.sBarcode(hres, vres,frmt)
where frmt is one of the ImageFormat types, such as ImageFomat.Png
Bitmap-type graphic images created with a specified pixel resolution are adjusted so that bar widths are an integer number of pixels, so that when printed on a device with that resolution all bar widths will be correct.
Prerequisites:
In the following guide we’ll create a local report (RDLC file) which features barcoding capabilities by using Bytescout Barcode SDK.
