I am currently trying to create a visual studio project with the visual studio sdk in C# following those steps :
- First I am using the DTE interface to open Visual studio
- Then I create a new directory
- Then I create a solution file
- Finally I create the project in the solution using a template
Here is the code below :
//Load DTE
Type t = System.Type.GetTypeFromProgID("VisualStudio.DTE.16.0");
EnvDTE.DTE dte = (EnvDTE.DTE)System.Activator.CreateInstance(t);
//Hide UI
dte.SuppressUI = true;
dte.MainWindow.Visible = false;
//Create new directory
if (Directory.Exists(@"C:\Temp\SolutionFolder"))
Directory.Delete(@"C:\Temp\SolutionFolder", true);
Directory.CreateDirectory(@"C:\Temp\SolutionFolder");
Directory.CreateDirectory(@"C:\Temp\SolutionFolder\SolutionTemp");
//Create solution
dynamic solution = dte.Solution;
solution.Create(@"C:\Temp\SolutionFolder", "SolutionTemp");
solution.SaveAs(@"C:\Temp\SolutionFolder\SolutionTemp\MySolutionTemp.sln");
//Create project with template
string template = @"C:\TwinCAT\3.1\Components\Base\PrjTemplate\TwinCAT Project.tsproj"; //path to project template
dynamic project = solution.AddFromTemplate(template, @"C:\Temp\SolutionFolder\SolutionTemp", "MyTmpProject");
Everything works fine but I have the window below that appears when i create my project but I want it to be hidden. Does anyone know how to hide the "project creation" window ?
PS : The project I am creating is a Twincat project (https://www.beckhoff.com/fr-fr/products/automation/twincat/) that is an IDE based on visual studio but it doesn't make any differences.
Thanks,
Emmanuel
