ALP is implemented as an Asynchronous Pluggable Protocol. It acts like a WEB server but without need of network. It executes WEB applications such as ASP pages and CGI applications. ALP makes Internet Explorer to be server and client. With ALP you can write stand-alone desktop applications, CD-ROM autoruns, use ASP for pure desktop software and still keep your code ready to run on WEB servers too.
Write desktop software in ASP and CGI!

Bugs and fixes

Please report bugs to the support@newobjects.com e-mail address. Please review the existing reports before sending the report.

ALP Fix 1 and upgrade 1a

Reported by: Sander Boshuis on 20 June 2001
Symptoms: Client side scripts are damaged in the output of the ASP pages
Cause: New line characters of the non-script content are discarded by the ASP parser.
Fix published: on 22 June 2001 and 27 June 2001

Fix: Package was updated. We recommend to download ALP again and reinstall it. Reinstallation is safe and will not cause your ALP applications, documentation was updated to reflect the change thus. If you have changed the samples in-place please backup them before reinstalling.

Updated files:

  • alpaspcontext.dll (from version 1.0.4 to 1.0.4.4)
  • ALP10.chm documentation file.

Details about the fix: New record entry was added in the scripts sections of the ScriptGen component. Entry is OutputLine, it specifies how to output lines with non-script content if they are at the end of the line.

Additionally with 1a fix we removed one limitation in the ASP support. ASP tags now can be used in the HTML comments too. Before this fix (versions prior to 1.0.4.4 of the alpaspcontext.dll) ASP tags were allowed only outside the HTML comments.

ALP fix 2 - included in version 1.0.5.3

Reported by: Sander Boshuis on 10 September 2001
Symptoms: Dead lock occured on some machines in case of usage of dynamically controlled images on the page or IE crashes during closing.
Cause: Mistake in a thread packing class and non-described behavior details during the DLL unload.
Fix published: on 14 September 2001 for the registered customers and on 17 September included in the 1.0.5.3 version of ALP.

Fix: Package was updated. We recommend to download ALP again and reinstall it. Reinstallation is safe and will not cause your ALP applications, documentation was updated to reflect the change thus. If you have changed the samples in-place please backup them before reinstalling.

Updated files:

  • Fix is included with the 1.0.5.3 version and most of the ALP files are updated because of the new features.
    Version information for the binaries in the ALP 1.0.5.3:
    • ALP specific: iewebsrv.dll (1.0.5.3 - shareware, 1.0.5.4 - retail), alpaspcontext.dll (1.0.5.3), cgstandard.dll (1.0.5.3)
    • Common: newobjectscollections.dll (1.0.0.3), scphost.dll (1.2.2.0)
    • ALPInstall (1.0.1.0)

Details about the fix: In the first version of ALP thread creation is controlled from the outside. In the last release threads was created on their own. One additional AddRef was misplaced and thread objects were destroyed in some situations before they are able to clean up or start their thread. Additionally during the unload process thread actually stops but windows API reports that the thread continues to run and this leads to wrong unload process in case of multiply IE windows spawned from one IE process - internal flag was added to distingush completition of the actual thread work from the thread state reported by the system.
