Hi,
I do use this script
https://dl.dropboxusercontent.com/u/40211031/CallDotNetDll.vbs

within Win 7/win 2008 server, to call this VB project
https://dl.dropboxusercontent.com/u/40211031/CSDemo.zip

while I also have followed these

Register COM DLL file in Windows 7
Start --> Run --> comexp.msc
Navigate to Console Root - Componet Services - Computers - My Computer - COM+ Applications.
Right click on 'COM+ Applications' and create New Application.
Follow the wizard carefully. Hit Next. Create an Empty Application. Name it (mycomapp1 for instance). Make sure Server application radio box is selected. Pick the user account based on the requirement. Hit Next. Next. Finish.
Now you have created a COM+ application named mycomapp1.
Now, you need to add individual COM components to it.
Expand mycomapp1 from the list. Right click on Components. Pick New Component.
Hit Next in the wizard. This next wizard screen is up to you. I would pick 'Install New components' if I haven’t run a regsvr32 or regasm on it. Pick the told or the dll (containing the tlb) file. And go ahead.. That’s how you do it.

to register both .dll and .tlb (which are built from the VB project) within the machine. but when running the VB script, I get the error attached

any advice?

run the vbs script as an administrator is my best guess as it is a permissions error

I was looking for an EE attached file or source.  I now see the file you have uploaded to Dropbox.  Please ignore my earlier comment.

From the variable names, I would guess that the ActiveX object expects double precision floating point parameter values.  Your VBS code is supplying string values.

Sorry, I was handling with Text only in the project.
Any advice to do any change?

First thing to try is to surround the parameters with parentheses
dblResult = objFunc.Func1((dblValue1), (dblValue2), (dblValue3))

Open in new window


If that doesn't work, cast the variables as strings
dblResult = objFunc.Func1(CStr(dblValue1), CStr(dblValue2), CStr(dblValue3))

Open in new window

In VBScript, all the variables are variant.  Do not include the As datatype clause to your Dim statements.

I don't have an environment that I can test the VB.Net project and your VBScript.
