VB DLL In ASP??

Hai all,
      I have creaed a dll in VB.
      Project Name : MyProj
      Class ModuleName : MyClass
 
      That Dll contains a function
      Public Function MyFunction(sName As String, tName As String) As Integer
On Error GoTo err1
    Dim data_Line As String
    Open (sName) For Input As #1
    Open (tName) For Output As #2
    Do Until EOF(1)
        Line Input #1, data_Line
        Write #2, data_Line
    Loop
    Close #1
    Close #2
    MyFunction = 1
    Exit Function
err1:
    MyFunction = 0
End Function


     Dll Name  : MyDll


      I registered MyDll.dll in Server using  regsvr32 command.

    I have created an ASP file In that file I used the following code...

Dim myObj
Set myObj = Server.CreateObject("MyProj.MyClass")
if myObj.MyFunction("c:\test.txt","d:\test_copy.txt")=1 then
      Response.write("Success")
else
      Response.write("Error")
end if
set myobj=nothing

this gets hanged....  in the browser

If I create another VB Exe Project and in that If I refer the dll and write the coding as

Dim myObj AS Object
Set myObj = CreateObject("MyProj.MyClass")
if myObj.MyFunction("c:\test.txt","d:\test_copy.txt")=1 then
      MsgBox "Success"
else
      MsgBox "Error"
end if
set myobj=nothing

and If I run this then I am getting the messagebox Success.

I am unable to trace the porblem. Can any one help me to solve this problem...

Thanks

Hello,

This is permission problem. Follow the procedure to overcome this problem.

In windows explorer select your source folder and destination folder (here they are C and  D drives).   And right click and select properties of those directories.  then select 'Security' tab.  Remove Everyone item from Name list box(If at all exists).   Press Add button   select  'IUSR_<Your Machine Name>' user.  give full control to the selected user.  Now run the asp program.


All the best,

Your problem looks like its in IIS/ASP side because you are trying to output
a text file to the d: drive, IIS will not let you do that, security reasons. Try creating the output file to the c: drive. Lets see what happens....
