Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

.NET dll Lock problem

    .NET dll Lock problem

    So after much playing around i've got .NET setup and doing a lot of our processing.
    The classes are registered as global variable, but i've found doing them locally on a accesible page creates unrecoverable overhead. They are persistant classes, thus needed for functions throughout regular use of the website. So I create once (on startup - see code below), and use many times - and it works perfectly.. apart from one problem, that i'm not sure is able to be fixed. But i'll ask anyway.

    Regardless of how they (classes, namespace, dll file itself) are registered and disposed of, i cannot make changes to the .NET assembly (IconLib2.dll) without shutting down the server.

    ASP.NET had "shadow copy" which allowed for changes to an assembly without restarting the server. It was able to finish currently running processes on classes in a copy of the dll, and allowed new execution on the new version. Maybe i can do some
    I guess i'm looking for a similar solution to that in Alpha or some way to Kill the lock it places on the dll?
    Its not something that is completely necessary (hopefully all code if tested before live - but always hard to tell what crazy stuff our users will throw at us). but would be very ideal to do.

    The reason for this is more so to revert fast to a previous version of the dll, this is if a change has been made in the dll that breaks things for a user, where reverting the old version would suffice - or doing a quick fix to the code and replacing with a new version. And to do so without interrupting all our users with a server restart would be ideal.

    Heres the code follows in the Autoexec code file for alpha five:
    (the ui_msg_box calls just let me know that the classes are successfully registered on startup of Alpha Five, if one returns NARP then i know i've got a problem with or in the assembly)

    Code:
    dim sv as DotNet::Services
    dim Alpha5Net4 as DotNet::AssemblyReference
    Alpha5Net4.FileName = "C:\temp\params\IconLib2.dll"
    
    if .not. file.exists(Alpha5Net4.FileName)
    	msg_txt = Alpha5Net4.FileName + " missing, stuff will not work!!!"
        ui_msg_box("Registration Failed",msg_txt)
    else
    	ui_msg_box("Registration Success","YARP")
    end if
    
    if sv.RegisterClass("IconLib2","HeaderFunctions","IconLib2.HeaderFunctions",Alpha5Net4)
    	ui_msg_box("Registered HeaderFunctions","YARP")
    else
    	ui_msg_box("HeaderFunctions not found :(","NARP")
    end If
    
    if sv.RegisterClass("IconLib2","GenericFunctions","IconLib2.GenericFunctions",Alpha5Net4)
    	ui_msg_box("Registered GenericFunctions","YARP")
    else
    	ui_msg_box("GenericFunctions not found :(","NARP")
    end If
    
    if sv.RegisterClass("IconLib2","ProcessWebsiteXMLImages","IconLib2.ProcessWebsiteXMLImages",Alpha5Net4)
    	ui_msg_box("Registered ProcessWebsiteXMLImages","YARP")
    else
    	ui_msg_box("ProcessWebsiteXMLImages not found :(","NARP")
    end If
    
    dim GLOBAL HeaderFunctions as IconLib2::HeaderFunctions
    dim GLOBAL GenericFunctions as IconLib2::GenericFunctions
    dim GLOBAL ProcessWebsiteXMLImages as IconLib2::ProcessWebsiteXMLImages
