Generate the equivalent of a DLL: a .netmodule

Wim Hoeks16-Sep-19 9:28

16-Sep-19 9:28

I am trying to bundle a coherent set of classes (one class per .h/.cpp pair) into a module to be distributed to my clients. So far when I link the classes to my test application using Visual Studio 2015, no problem. But when I configure project with the classes as input to generate a NET module, I get a warning about the manifest file not properly included in the generated module (warning starting with the keyword METAGEN), and when I want to link it to my test application, the linker cannot find the class methods. Sofar I checked the obvious settings such as OptimizeReferences, which would leave my module virtually empty (as I observe it).
It seems to me that working demo solution with two project would get met going, where the first project packages the clases, let's say three classes with only one method and the obvious constructor, get combined in a module, and a second project that uses the module to get access to classes and their methods.
Thanks in advance.

i have been trying to create setup file through setup and deployment template in vs2010. so now i have successfully added all files,folders,shortcuts and dlls etc.. but i have strucked at adding prerequisites to my setup application.i researched and found many articles but those all are telling to add prerequisites from the same computer,yes i followed and done it successfully, but when i try to install that setup in another computer(which is not installed vs2010 and .Net framework in it) its tending for .Net framework and redistribute components. the client computer installed with win7 32 or 64 bit OS (which will have no internet and not installed vs2010 as well). i just want to distribite my setup file which included prerequisites and redistributable components so that client simply install it and run the application.by the way i am using vs2010 ultimate to build the setup in win7. so is it possible to do that? i have been trying to do it from past three days but i couldn't, so finally i came here. please help me to solve this issue.thanks in advance.

thanks for the reply but i think its not an issue about version of the .Net framework. my project using .Net 4.0 and i selected the same in the prerequisite dialog box, (FYU) i selected the third option like "download prerequisite from the following location" but after giving successful path and built the setup. when i install the setup in another computer its searching for .net framework from the web.this is what i can't understand. please suggest any link with detailed procedure (i am trying with MFC application).thank you

If they don't have access to the internet, then you have to provide the whole .NET framework as part of your installation: it is large and not normally included as it is downloaded as needed when the installer finds the right version isn't installed. Win 7 ships with .NET Framework 3.5.1 so any fresh(ish) installation that you try to add your .NET 4.0 app to will need to install a more recent framework before it gets anywhere else.

No internet? You need to supply it.

You can't just install the DLL's for .NET V4.0, you have to install the whole framework properly. That means following the link I gave you, and including that as a part of your installation. That's because you don't have the internet, which MS usually use to ensure the right version of .NET is installed prior to the main installer starting.

Gawd knows if the V40 framework will work on XP at all: I don't! A quick check with MS says it will, if XP is at SP3 - which if it's not on the internet, it very probably isn't ...

yes,sorry for the late, i have moved to another bug. so i am using the template "Visual studio installer" on win7 32-bit OS.all prerequisites are added successfully like vc runtime components, my application related dlls, from the prerequisites dialog box i checked "microsoft dotnet 4.0 client,4.5" and "windows installer 3.1" but it couldn't be included in it i think.after built successfully the setup is going to run on winXP, Win7 (32/64) bit Operating systems. now i installed it on XP machine ,its searching for dotnet framework in the web,when i installed it on win7(32-bit) machine its showing the error like msvcp100d.dll is missing. my mfc vc++ application's target framework is dotnet4.0 so that's why i have checked 4.0 version also from prerequisite window,but i got same result as above. so what would be the exact missing in my setup..? thanks for your patience...

I have 3rd party . OCX file. which loads in HTML scripts and do desired work

Below Steps I have used while creating a Wrapper:

1: In visual Studio-> VC++-CLR-ClassLibrary project
2: Project add Reference (.ocx file)
3: Ref: i am abe to see Interop.Filelib.1.0
4: now in Project.h i am trying to use Filelib but not able to create any object or instance.

While i tried to create an Activex project and added .ocx file getting below stuff and i am not able to understand how to use it and create an wrapper for C#.

class CDNXCardReaderX : public CWnd
{

CLSID const& GetClsid()
{

return clsid;
}
virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle,

BSTR bstrLicKey = NULL)
{

{
long result;
static BYTE parms[] = VTS_I4 ;
InvokeHelper(0x2d, DISPATCH_METHOD, VT_I4, (void*)&result, parms, Timeout);
return result;
}

I am totally clueless on what approach shall i use to create object and call these functions.

I have a program that works fine on most machines. Every now and then I find a

shifting here

http://ruthtechnology.com/temp/Untitled2.jpg[^]

In the past, I use to be able to go to display settings and change it from 125% to 100% and reboot and the boxes would line up nicely with the form. But its on a 100% and I dont know why its not lining up.

Any comments or suggestions are greatly appreciated.

Generic List Template, Function Parameter

Hello All.

I'm trying to create a function that can loop through a list of Windows::Forms::Controls (I know there's no loop below, I'm just keeping it simple for sake of testing) and perform a task. Right now I have a function which works properly:

C++

 void mCtrlWrap::IsVisible(bool TF, List<Windows::Forms::TextBox^>^ list)

{
	if (TF == true)
	{
		list[0]->Visible = true;
		list[0]->BackColor = Color::Azure;
	}
	else if (TF != true)
	{
		list[0]->Visible = false;
	}

}

but i want to make the List parameter a template so that it take List<windows::forms::combobox^>^ as a parameter or List<windows::forms::label^>^, etc.

I've tried

C++

template<typename T>
 void mCtrlWrap::IsVisible(bool TF, System::Collections::Generic::List<T>^ list)

{
	if (TF == true)
	{
		list[0]->Visible = true;
		list[0]->BackColor = Color::Azure;
	}
	else if (TF != true)
	{
		list[0]->Visible = false;
	}

}

which compiles just fine but i get linking errors:
1>MainScreen.obj : error LNK2020: unresolved token (06000001) mCtrlWrap::IsVisible<system::windows::forms::textbox ^="">

can someone please help me figure out what I'm doing wrong?

Thanks

Brennan

In C# you would handle this by casting each component to a Control object. I assume you can do the same in C++/CLI.

Also, why do you need the else if clause above? TF can only be true or false, if it is not true then you only need a simple else clause for the second block, thus:

C++

if (TF == true) // or just if (TF)
{
    // what to do if it is true
}
else
{
    // what to do if it is false
}

You are mixing C++ template and .NET generics. This is OK is you understand what are you doing.
In your specific case, this is classic C++ template problem. To call templated function C++ compiler must see the function implementation, and not only prototype. So, you can instantiate IsVisible function only in the same .cpp file. Or make it inline by moving the function implementation to .h file.
