ADT2: Setup Wizard Fails to Create Disks Compressing Large File

ID: Q156195

The information in this article applies to:

Microsoft Access Developer's Toolkit, version 2.0

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When you try to create distribution disks by using the Setup Wizard that comes with the Microsoft Access Developer's Toolkit version 2.0, the disk images will not be created successfully if you include a file that is so large that it takes more than 9 compressed files. You may also receive the error message:

Can't create file.

CAUSE

The reason for this behavior is that the Setup Wizard creates compressed files in the following format:


   mydb.md_
   mydb.m2_
   mydb.m3_
   ...
   mydb.m9_
   mydb.m10_

MS-DOS does not allow extensions that are greater than three characters for file names. Therefore, a file with an extension such as mydb.m10_ will cause the creation of the disk images to fail.

RESOLUTION

You can edit the code in the Setupwiz.mdb so that the Setup Wizard can create compressed files in the following format:


   mydb.md_
   mydb.2_
   mydb.3_
   mydb.4_
   ...
   mydb.10_

To modify the code in the Setupwiz.mdb, follow these steps:

Open Setupwiz.mdb while holding down the SHIFT key.

Open any module in Design view.

On the Edit menu, click Find to bring up the Find dialog box. In the Find What box, type "_" and in the Search option box, select Loaded modules, and then click OK. This should bring the pointer to the following line in the module zws_Setup:
```
stFileDest = Left$(stDest, Len(stDest) - 2) & Format$(cChunk) & "_" 
```

In the line, replace the - 2 with - 3.

Save the module and close Setupwiz.mdb.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Access Developer's Toolkit version 2.0. This problem no longer occurs in Microsoft Access Developer's Toolkit for Windows 95.

MORE INFORMATION

Steps to Reproduce Problem

Create a very large mdb file with a size of 70 megabytes (MB) or more, or include several mdb files for distribution.

Use the Setup Wizard to create distribution disks.

Note that if more than 9 compressed files are needed to create the distribution disks, the Setup Wizard fails to create the disk images.
