I have a small vb6 app that has no database behind it.  I would like for my ms access adp app to launch the vb6 app and return a value.

Is this possible? I have been trying for 2 days

As an EXE?  No.

Can you compile the VB6 stuff as a DLL?  If you do that, you can get a return value from a function call to that DLL.

You could do a couple of things here
1.  You can call the other application from a shell command
cPath = "\\Server\AppPath\"
Shell cPath & "AppName.Exe",vbNormalFocus

2.  You can pass information by writing to a file from App2 and reading it from App1
    Have App1 wait for the file if necessary with a timeout then read the response and remove the file afterwards...

3.  Have App2 write to a registry location that App1 will read from.
    App1 can set the registry value to a default or a wait value, App2 can write to Same registry value
   App1 can read from registry until changed by App2 or TimeOut

Set your VB6 project type to ActiveX EXE and place your code in a public method on a public object.

In your MS Access VBA project add a reference to the EXE - Tools | References... | Browse...

You should be able to confirm that your VB6 object is now accessible in the Object Browser - Press F2 and change <All libraries>

Now you can call your EXE from code using the following:

Dim oMyProject
Dim retVal
oMyProject = New MyProject.MyObject
retVal = oMyProject.MyMethod

Open in new window
