I need to read\write tga files from vb,
I found TargaImage.dll, nice lib but it allows only read tga.
I found FreeImage, tryed to import it in vb, but it says:
FreeImage.dll could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.
I think I have to use , but absolutly dont know anything.
help plz:)
From looking at the way the distribution works, you have two options:
First, you could call the functions in the DLL directly using <DllImport> attributes. This is going to require a lot of learning of how to make calls to unmanaged DLLs, passing the right values, etc. Which is why I suggest the second option.
The second option is, you can use the .NET Wrapper project that is included in the distribution. If you're using a version of Visual Studio that supports multiple programming languages, just add the wrapper project to your solution and reference the wrapper project from the project that needs to use it.
If you're using Visual Studio Express, you won't be able to add a C# project to a VB solution. I'd suggest downloading C# Express, compiling the wrapper project, and then adding the compiled DLL to your VB.Net project.

Is there any way, I can prevent my c++ cli project from being decompiled if someone uses a C# decompiler, because I tried to decompile the .exe i made in ILSpy and it showed my whole code, so is there any way I can prevent this?
Thanks
as ancient as this thread is, I ran across it with the same question, and a newish answer. Can't specify the minimum version for this one, but
[module:System::Runtime::CompilerServices::SuppressIldasmAttribute];
on top of each .cpp module did the trick for me:
I didn't investigate much further, yet.
Another useful thing is to add
#pragma unmanaged
to each .cpp that does not contain .net code.
You can
Use a .NET obfuscator.
Or
Only use C++CLI for the boundaries of your app which require to Interact with .NET. And implement your logic in a native C++ library.
I am a javascript/html developer that hasn't ventured into visual studio much, so this might be a trivial question.
I am currently developing a Windows Store app (winJS), that will likely turn into several apps. And it would be highly likely that I will be reusing code, so I have made a js library with the common code.
The question is, how can I develop on this lib in visual studio, so that the apps that I am developing will use the latest version of it (i.e without me having to copy the files in again manually).
Best thing I can think of is, create a new project for the lib, and include it in the applications solutions, but what type of project would it have to be, and how to you expose the files?
Hope that makes sense!
Thanks!
I usually solve this by having the project copy the JS files I want to a common location, and add that file to the target project using a LINK to the file I want to include, rather than just adding it -- this is on the "Add Existing File" dialog, under the little arrow on the "Add" button.
VS 2012 doesn't have a JavaScript library project type. You'll have to manage your library as loose files.
The easiest thing would probably be to create a nuget package. That way it would be easy to pull into other projects and have the tool help keep you up to date. It does have the downside of needing to put your stuff into a nuget feed, which is not something you want for private stuff.
so my question is relatively simple, can I create VB6 application that references a class in a dll, and then substitute that dll for another at runtime?
Now my intial guess is... no chance in VB6.
So my thoughts turned to a VB.net interop dll. Could I do it in here, and then call the interop dll from the VB?
Again, my guess would be no.... but I'd be happy if someone knew differently.
The only thing that I think would actually work would be DI in .Net, but I'm limited to .net 2, or 3.5 at a big push, so I dont know if that is possible.
So for the background....
I have a dll that a specific site uses, but we dont want to ship that out to everyone. Instead, we want to build a clone dll which just has the interfaces setup so that the VB6 build will complete.
When it gets to the site that needs it, they want to replace the dummy dll, and drop in their version instead.
Note: We do use RegFreeCOM when its gets installed, so I do have the manifest files that I could play around with if needed.
Any ideas would be much appreciated.

Its a COM dll so its not statically linked to the VB6 exe, so long as the clsids and interface ids are the same in the type library for both DLLs, you can swap them around as you see fit. (If its a VB6 dll this is trivial to do with the 'binary compatibility' build option)
You could also use late binding instead and instead of making a reference directly in your VB6 code, you would create an object and then set that object to an instance.

can anyone give me some steps to create DLL without using class which means it will just have methods in the header file and source file would be only DLLmain() plus other methods. I'm using Visual Studio 2005 to create MFC DLL, but it always generates class. I never create DLL before but I was told that I can create DLL without class/object oriented concepts, just plain functions.
thanks.
For a regular Win32 DLL:
In the New Project wizard, under Visual C++ / Win32, choose Win32 Project.
Then in the next page, choose DLL as application type.
You may want to select Export functions as well to get sample code of exported variables, functions and classes.
From there on, simply delete what you dont need (such as classes).
I no longer have the Windows Mobile SDK installed, but I'm pretty sure you'll find the same kind of wizard to create a Windows Mobile DLL project.
Of course, if you don't want C++ classes, forget about MFC!
I need to convert all types of audio formats to the mp3.
I think I need to add the refrence of the dll (lame_enc.dll) into my .net application.
When I try to add the DLL reference to my project, I get an error: "A reference to C:\Lame_Enc.dll could not be added. Please make sure this file is accessible and that it is a valid assembly or COM component"
Is there any other solution that I can convert all types of audio formats to the mp3 and also I need to convert all types of video formats to the flv.
Many thanks for your consideration.
Why reinvent the wheel? Here

you find a .NET wrapper library for lame_enc.dll. It is written in C#, but usage from VB.NET should be no problem.
By the way, if you want to use native DLLs (no COM, no .NET) from a VB.NET program, you don't have to add a reference to that DLL, you just have to copy that DLL into your working directory of your VB.NET program and use PInvoke. Read this tutorial (C# only, sorry)
