Zip and Unzip Using VB5 or VB6. This code shows how to use the freeware Info. Zip Zip. 32. DLL and Unzip.
DLL files from the. I've included the two dll's in the download file at the end of this article. The Info. Zip DLL's are open- source DLL's that are available for programmers to utilise free of charge. They are standard C DLL's and were very tricky/impossible to interface with VB until VB5/6 offered the 'addressof' operator. About this Code I based this code on the Zip/Unzip examples that come with the downloadable DLL's and encapsulated that code into re- usable class modules that can either be used in an Active.
X DLL, or just placed into your project as required. The downloadable project contains the source- code for an Active. X DLL called CGZip.
Library and a sample project which uses that DLL. The example program simply takes everything in it's own directory and zip's it into a file. You can then unzip this file straight into the TEMP directory. You can check the structure of the Zip file using Win.
Learn how to use Zip and Unzip compatible methods with VB5 or VB6. All the code is contained in class modules that can either be compiled into an ActiveX or dropped.
Zip (or similar) if you want to check that the Zip is intact (I've had no problems with it at all). The Class Modules CGZip.
Files and CGUnzip. Files have a lot of properties - it's worth reading through the code in these classes to learn how to get the best from them. A sample piece of code using the Zip class could be as simple as . Dim o. Zip as CGZip. Files. set o. Zip = new CGZip. Files. o. Zip. Zip. File. Name = "\My.
The first thing I could think of was to restart the Apache httpd service. This immediately solved the issue. but I knew this is not a permanent fix for the.

It's designed as a starting point to allow you to use Zip and Unzip functionality in your programs. You should really place the Zip. DLL and Unzip. 32. DLL into your \windows\system directory (although you can just have them in the same directory as the Active. X DLL). I've been a version of this code for several weeks in a production application and it's just been superb. I hope you enjoy the code!
Thread: [VB6] Unicode File Open/Save Dialog. Updated the Unicode.
Browse. Folders class. Added a self- contained callback function that uses JIT (just- in- time) thunk creation in order to callback to a class procedure so the class doesn't need to have an additional bas module.- This callback is automatically invoked if you set the Initial. Directory or Initial. Directory. PIDL properties.
Custom. Hook. Proc must not be set to use this default callback. You will not get any events from this callback procedure.- This option is ignored if you set the Custom. Hook. Proc property to use your own hooks- The Custom. Hook. Data() property is ignored if Custom. Hook. Proc is not set. Added 2 properties to set the startup/initial folder by either string path or PIDL (needed for virtual folders like Control Panel) - Initial. Directory property sets the startup as a string path- Initial.
Directory. PIDL property sets the startup as a PIDL, which you are required to destroy- Setting either of those overwrites the other. Added option to set the Root folder as either a string path or PIDL- Set. Root. Folder requires a string path (no change)- Set.
Root. Folder. PIDL (added) requires a PIDL, which you are required to destroy- Setting either of those overwrites the other. As with the previous version, the main function Show. Browse. Folder has a parameter to prevent the class from destroying the PIDL returned by the API used to display the dialog. However, you may not know in advance whether or not you want to destroy it, but also don't want to be forced to destroy it after each call.
So, modified the logic a bit. If Show. Browse. Folder's optional parameter Release. PIDL is set to False, then existing logic remains. The class will never destroy the PIDL.
You are required to and the PIDL can be retrieved from the new Selected. PIDL() property. Can be destroyed with Destroy. PIDL()b) If Show. Browse. Folder's optional parameter Release. PIDL is set to True, then existing logic was modified and works this way. The PIDL will be destroyed whenever Show.
Browse. Folder is called again. However, if you decide you want the PIDL (possibly to be used for Initial. Directory. PIDL or Set. Root. Folder. PIDL), then you can take ownership of the PIDL and the class will not destroy it. To take ownership, call Selected.
PIDL(True). If the optional parameter of that property is set to True, then the class will never destroy the PIDL, but you must, at some point. Note: Set. Root. Folder. PIDL & Initial.
Directory. PIDL will not allow you to use the PIDL returned from the previous call to Show. Browse. Folder unless you took ownership of it. Some properties had their names changed to be more intuitive: - Selected. Item changed to Selected. Folder- PIDL_Return.
Value changed to Selected.
