I'm doing VB coding using Visual Studio 2008.
How to import a .dll file into my program?
Can anyone help me please.
Thank you.
Add the reference (From your menu Project->Add Reference and browse for the dll file)
Put Imports DLL.Namespace at the top of your code.
You need to add a reference to the DLL...
Right click references in the project explorer
Click on the browse tab
Browse to your dll
Add a using statement in your code which points to said DLL

I'm making an expert system using VB.net 2010
I already downloaded the Mommosoft.ExpertSystem.dll in CLIPS.NET
Assuming that I already made the Knowledge-based file with CLIPS, how to I integrate it to VB.NET?
In Visual Studio you right click on solution file > click Add References > add the Mommosoft.ExpertSystem.dll
Then in your VB.Net project you will then be able to call methods in the DLL, eg
Mommosoft.ExpertSystem.DoSomething()
I am working with Visual Studio 2010 on a Windows 7 64-bit system. I am coding in vb.net. I am trying to use the SpreadsheetGear DLL (D:\VS2010Code\Report Depository\Bin\SpreadsheetGear.dll) in my DashInApps (D:\TWhitsett\DashInApps) project to load my output data to Excel. Can someone assist and guide me in the right direction to get this done?
Right click on your project and click 'Add Reference'. Then point to the SpreadsheetGear DLL in question. You can't just put it in the bin directory and expect it to work without loading it into the project first.
Just to start off, this question does seem very similar to another post Add the DLL (lame_enc.dll) reference to my project, but I haven't been able to successfully apply that answer. I am pretty new to VB.NET so it is very possible I'm simply missing something obvious.
I am trying to link a DLL to a VB.NET 2010 project to allow my VB app to play *.ogg files. I followed some other advice here on the forums and downloaded FMOD's FMOD Ex Programmers API. I am trying to now reference that functionality. These appear to be the files I need to somehow reference.
C:\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\fmodex64.dll.
C:\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\libfmodex64_vc.lib.
I haven't discovered how to add a *.lib reference (or the equivalent), but selecting the DLL as a reference gives the following error.
A reference to 'C:\Program Files (x86)\FMOD SoundSystem\FMOD
Programmers API Windows\api\fmodex64.dll' could not be added. Please
make sure that the file is accessible, and that it is a valid assembly
or COM component.
I'm not sure what I could be missing. Any ideas? Thanks!
In Solution Explorer, double-click the My Project node for the project.
In the Project Designer, click the References tab.
Click the Add button to open the Add Reference dialog box.
In the Add Reference dialog box, select the tab indicating the type of component you want to reference.
Select the components you want to reference, then click OK.
Another approach I was trying is working for me. I found a site with a working example of a LibZPlay VB.NET sample ( http://planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=7789&lngWId=10 ). It runs under VS 2008 and I was able to adapt my project to use LibZPlay (open source library http://libzplay.sourceforge.net/WELCOME.html ) under VS 2008.
That is sufficient for me for now. Thanks for your advice. It was likely some configuration issue or misunderstanding on my end.
Using VB.net 2015 I (could not add or even find a System32 dll) as a reference using Solution Explorer, Tab References. Going to the MAIN Menu, Projects/Add References...
Used Browse and All the System32 dll were visible. Then I was able to load the needed dll.
What is a standard way to open the Designer (automatically generated) code for a VB file?
As a workaround, I can get to it by searching the entire solution for some keyword that is usually only found in those files: Global, Partial, etc.
Open the Solution Explorer. Along the toolbar at the top there is a tool Show All Files (it is the 2nd from the left on my version of visual studio). Click on that tool. All of your Form files will now have an arrow beside them. click on that arrow to expand. Look for the code file named FormName.designer.vb. Double-click on it to open.
You have to click the "show all files"-Button. Then you can also see the Designer.vb-files.
Note: For C# and VS 2008, but the same applies to VB in VS 2010.

Keyboard shortcut for Show All Files
Show All Files is a useful little button in the Visual Studio solution explorer to give us a full view of the directory structure our project files are sitting in. When it is off, we only see the files that are explicitly included in the project, but when it is on, we see everything. This makes it very easy to explicitly opt a file into the project without doing an add -> existing item -> find existing item in directory structure and add to project.
The default when creating a new Visual Basic application in Visual Studio is to not show all files, and unfortunatly there is no setting you can adjust to change that.
Open the code file, and in the top-right corner of the code window is a drop-down containing all methods. Open this and select "InitializeComponent".
A screenshot from a newer version. Visual Studio 2015 and 2017 will look like this.
I have a problem with the style of the button in a messagebox.
If I call the following line of code in a current project the button get one type of visual apperance/style. And If I create a new VB.NET Windows Application project it gets a standard Windows apperance/style.
Windows.Forms.MessageBox.Show("Yaay", "Yaay!", Windows.Forms.MessageBoxButtons.OK)
See the difference between the buttons below.
I suspect they inherit the visual apperance from it's parent or maybe from some project settings. But I have not been able to find out from where.
Both projects are created in VB.NET 2.0, and both have same System.Windows.Forms - dll as reference (c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll).

Thanx in advance for your help!
I cannot see the image from where I am so I'm not sure if this will help you.
Open the Project Properties for each solution and look at the Application tab.
Is the "Enable Applicaton Framework" item ticked? And if so, is the "Enable XP Visual Styles" item also ticked?
That may the difference in the two solutions.
