I have merged another project in my existing project by right-clicking on the project name and selecting Add->Existing project option. Now i wan't to access the files from my newly added project from the existing one in Visual Studio (Its a C# project) , how can i do this?
回答1:
If I'm following your question, you had a solution with a project A. You then added an existing project B.
You now want to access a file from A in B. If that's the case, right click on the B -> References and add a reference to project A. Now you can use the files from that project.
Edit: From your comment, I'm not sure if you want to have a separate project / file. If you want them to be only 1, you shouldn't really add a new project, you should add to your project A the files you need from project B. If you want to keep it as a different module that is included, then the above holds, but you need to realize that usually you have one solution, with many projects inside of it.

I struggle with this until I found this the link is below:
If you want all windows application to run as one program rather then calling multiple .exe. Then change 'Out Put Type' of each project to 'Class Library'.
Step 1:
You can do that by right clicking on each Project in solution -> Go to Properties -> Application -> Out Put Type... set it to Class Library
Once you have done that out put of these will be generated as .DLL.
Step2:
Add a new Window Form application project, add reference of exiting projects in it so that they can be executed from here.. you can do that by.. right click on main project-> Add Reference->Projects select all existing projects from here..
Now on main application you can create 3 buttons to launch each project...
[Inventory]
[Accounts]
[Payroll]
Now in each button code will be something like that...
Inventory_click()
{
Inventory.MainForm frm=new Inventory.MainForm();
frm.show();
}
