Use of DLL written with c#

[josipradnik]

If I properly understand where to put int(),

?ox2.dynamicCall("foxproc5(int(),int()",3,4)
.F.

Beta5, the same result in all four variants.

No, on your parameters not the signature.

ox2.dynamicCall("foxproc5(int,int)",int(3),int(4))

[josipradnik]

Nothing shows. No .F. result.

Hi Josip,
thanks for all your sample..

but my DLL don't work.

Is possible that the problem is on the DLL.. I don't know.. I don't use never VS and c#.

I perform other test...

One question, my c# dll file is: GeneralInputOutputServiceGroupCGK5188.dll
I need to copy the file into c:\windows\syswow64 and register it before use?
Or I need to copy the file where is my Lianja/VFP prg?


thanks
Fabio

I need not to worry about registering it because C# project has set in its Properties,
Tab "Build Events",
in "Post-build event command line" something like that:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\gacutil.exe" /u PLUS.Lider
"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\gacutil.exe" /i "D:\....yourfolder\yourdll"

(In fact, the last part is: ... /i "$(TargetPath)" , depending on "Output path" from previous tab)

and "Run the post-build event" is specified:

On successful build

After rebuilding solution/project, DLL is registered in Windows GAC (C:\Windows\Microsoft.NET\assembly\GAC_32).
And regardless where is now DLL located, I can in Lianja

ox = CreateObject("vfpcomserver.vfpcom")
?ox.dotnet('PLUS.Lider.Client.LiderClient','ScreenResolution()')
1600x900

Starting part of my C# (after few usings) is:

namespace PLUS.Lider.Client
{
    [ComVisible(true)]
    [ClassInterface(ClassInterfaceType.AutoDual)]
    public sealed class LiderClient
    {
...
        public string ScreenResolution()
        {
            return Screen.PrimaryScreen.Bounds.Width.ToString() + "x" + Screen.PrimaryScreen.Bounds.Height.ToString();
        }
...
        public string GetGUID()
        {
            string Guidd1;
            Guid c = Guid.NewGuid();
            Guidd1 = c.ToString();
            return Guidd1;
        }

this:
[ComVisible(true)]

give me a error...

I'm too newbie to VS..

Hi Fabio,

You should show me error text or a screenshot.

I suppose your C# does not start with

using System.Runtime.InteropServices;
