how to invoke the Shell command with a dotnet assembly

bultela

Hello all,

I am creating inside Navision a calculation engine with a more or less complex structure.

Example, after having calculated the value of all my variables, I get the following expression in a field :
(18*(3/(4+2))*5)/3 +9

The number of brackets can change. It is difficult to do it in Navision;

That's the reason why I had the idea to run the windows calculator (without opening it) to pass in the calc.exe program the expression (example : (18*(3/(4+2))*5)/3 +9) and to get the result (24).

I thought at the shell command which could be run before NAV 2013 with an automation variable.
But I have now to do it with Dotnet;

Does anyaone have an idea of the name of the name of the assembly to use and which syntax can be used to run the calculator with a formula as parameter ?

I woul really an answer from you.

Best regards

Thnak you for the answer;

its works.

I had already seen this post but could not find the assembly system.diagnostics.process.

The reason is simple : I had to select the assembly SYSTEM first and that's all.

there are in the list other assemblies which have quite the same name but not the same.

The only place I know to invoke the "shell" command is from the visual basic core library.

Within the Microsoft.VisualBasic.Interaction namespace is the Shell method, MSDN here http://msdn.microsoft.com/en-us/library/f92d6y8s(v=vs.110).aspx?appId=Dev11IDEF1&l=EN-US&k=k(Microsoft.VisualBasic.Interaction.Shell)%3bk(TargetFrameworkMoniker-.NETFramework,Version%3dv4.5)%3bk(DevLang-VB)&rd=true&cs-save-lang=1&cs-lang=vb#code-snippet-1

Using this method you can create a process without using the additional code.

Define two variables:
vbShell of DotNet using Microsoft.VisualBasic.Interaction.'Microsoft.VisualBasic, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
vbAppWinStyle of DotNet using Microsoft.VisualBasic.AppWinStyle.'Microsoft.VisualBasic, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

The C/AL code required is as follows;

vbShell.Shell('c:\somedir\somefile.exe', vbAppWinStyle.Hide, FALSE, 0);

Much simpler but less control.
