Re: [PHP] Using DLL with PHP
MAYBE a little closer to a solution!
//VB for Reference
Private Declare Function DTM_CONVDMSToMultiTIFF Lib D32_CONV.DLL _
(ByVal FullPathFrom As String, ByVal FullPathTo As String) As
Integer
Public Function hello(ByVal name As String) As String
hello = Hello name World!
End Function
Public Function DMStoTIFFconv(ByVal FullPathFrom As String, ByVal FullPathTo
As String) As String
Dim DMSconv As Integer
DMSconv = DTM_CONVDMSToMultiTIFF(FullPathFrom, FullPathTo)
End Function
//PHP Code
?php
function Hello() {
$new_com = new COM(DMStoTIFF.conv);
$output=$new_com-hello('Happy'); // Call the hello() method
echo $output; // Displays Hello World! (so this comes from the dll!)
$convert=$new_com-DMStoTIFFconv('C:\\TEST\\04186177.dms','C:\\TEST\04186177.tif');
}
Hello();
?
So, previously I was having issues calling the D32_CONV.DLL...
I think I am past that now.
If I comment out
$convert=$new_com-DMStoTIFFconv('C:\\TEST\\04186177.dms','C:\\TEST\04186177.tif');
the Hello Happy World text prints to the screen no problem.
But when I try to access the VB to call the actual DTM_CONVDMSToMultiTIFF
function I am getting one of two errors. I am either timing out, or getting
a message saying incomplete headers.
The D32_CONV.DLL file is a conversion library that will convert a file from
DMS format to TIF based on two parameters. Since this function is converting
a document, do you think my problem is trying to assign that to the $convert
variable instead of a file output location?

I wouldn't think it should matter much, but I notice you've got your
VB function declared to return a String, and never give it a value.
Shouldn't it just return the Integer value that the internal function
call is returning?
' VB Function
Public Function DMStoTIFFconv(ByVal FullPathFrom As String, ByVal FullPathTo
As String) As Integer
DMStoTIFFconv = DTM_CONVDMSToMultiTIFF(FullPathFrom, FullPathTo)
End Function
Also, I'm wondering whether the double-slashes are getting passed into
the object method rather than being treated as escape characters. You
might try passing one of those values to your Hello() method to make
sure they are going into your class correctly.
This also doesn't begin to delve into whether the COM object uses the
same security context as PHP. I would think so, but that's just a
guess.

Re: [PHP] Using DLL with PHP
Alrighty, so I went a different route...
I created my own ActiveX DLL...one that I know I can register.
Starting out really simple:
//My VB code
Public Function hello() As String
hello = Hello World!
End Function
//My PHP code
?php
function Hello() {
$new_com = new COM(DMStoTIFF.conv);
$output=$new_com-hello();
echo $output;}
Hello();
?
So, after I register the DLL on the server my PHP page is correctly
displaying the Hello World! dialog.
What I'm having problems with now is trying to pass a variable to the DLL.
Shouldn't I be able to do this just like any other PHP class/function?

Generally I think you can. You may run into issues where the function
parameters and return values must be defined as variants in your DLL,
or you may need to cast your PHP variables into instances of the
VARIANT class.
In ASP I mostly used the Scripting.Dictionary (like a hash table, I
guess, since arrays in VBScript are all integer-indexed),
Scripting.FileSystemObject, the ADODB library for database access, and
sometimes a utility to manipulate images, process file uploads, or
file compression. PHP already has extensions for all of these, so I
haven't had to delve into the complexity of using COM in PHP.
Just for kicks, I just tried this in Zend Studio which is running PHP
5.2.0 under WinXP, and it worked as expected:
?php
$some_file = ''; // PATH TO SOME FILE
$x = new COM('Scripting.FileSystemObject');
if ($x-FileExists($some_file)) {
echo 'The file exists!';
} else {
echo 'The file does not exist.';
}
?

It doesn't appear that your function accepts a parameter. What does
this do:
//VB
Public Function hello(ByVal name As String) As String
hello = Hello name !
End Function
//PHP
echo $new_com-hello(Dan);

Alrighty, I'm trying to use the COM function, but not getting much of
anywhere.
This is what I have:

//Create a function in PHP to call the DLL

Any ideas?

I can't help much, but this might get you started.
1) Does the DLL you are trying to use actually supports COM. I know some don't.
2) I'm pretty sure that the string you pass to new COM('...') should
be the name the class as registered with Windows, not the actual file
name. They are usually something like 'Scripting.FileSystemObject',
'word.application', 'ADODB.Recordset', etc.

1) Does the DLL you are trying to use actually supports COM. I know
some don't.
2) I'm pretty sure that the string you pass to new COM('...') should
be the name the class as registered with Windows, not the actual file
name. They are usually something like 'Scripting.FileSystemObject',
'word.application', 'ADODB.Recordset', etc.
I believe you can also call it by its Public Key Token (a GUID), though that
may be a new convention introduced with the .NET framework that is not
backwards-compatible with plain COM objects...

The DLL I am trying to work with was written by an outside agency.
Their application uses this dll to convert DMS images (Their proprietary
format) to TIFF images.
Naturally they are not very forth coming to share the functionality of their
software, but I was able to get the VB function that calls the DLL for
conversion.
Private Declare Function DTM_CONVDMSToMultiTIFF Lib D32_CONV.DLL _
(ByVal FullPathFrom As String, ByVal FullPathTo As String) As
Integer
So, I was hoping to be able to call that DLL in PHP and pass it the two
values I specify in my application.
In order to be used by COM is the DLL required to be placed in the SYSTEM or
SYSTEM32 folder?
No. When I was doing an ASP (not .NET) site, we registered them from a
custom path just for our web app.
Or does it have to be a DLL that can be registered?
I believe you do have to register it with regsvr32 for it to be visible.
I think the GUID that Todd mentioned might even work, but I've only
ever used the ProgID. If you don't know the ProgID that is registered,
you should be able to find it in the Windows registry after you've
registed it with regsvr32. If you search for the file name, it should
find an entry somewhere under \HKEY_CLASSES_ROOT\CLSID\(some
GUID)\InprocServer32 that has a value of the full path to your DLL
file. The ProgID is the next key down below InprocServer32, labeled
aptly ProgID.

in c:\Windows\Assembly). I believe your ProgID suggestion will work just fine
for pre-.NET DLLs, anyway. :)
