    UploadProvider does not support file system

    Reply Quote
     
    I am following the instructions in this article in order to implement a custom provider which does not write temporary files to disk (I am doing this because my application is load balanced on multiple web servers and I don't have access to a folder that is accessible and shared by all web servers).
     
    However, I am getting the following error:

    UploadProvider does not support file system.

    Stack Trace:
    CuteEditor.UploaderEventArgs.GetTempFilePath() +191
    CuteEditor.Dialogs.FileBrowserPage.a(Object A_0, UploadEventArgs A_1) +1598
    CuteEditor.UploaderBase.OnFileUploaded(UploaderEventArgs args) +97
    CuteEditor.UploaderBase.a(UploaderProvider A_0, UploaderEventArgs A_1) + 164
    CuteEditor.UploaderBase.a(String A_0) +1272
    CuteEditor.UploaderBase.System.Web.UI.IPostBackDataHandler.RaisePostDataChangedEvent() +133
    System.Web.UI.Page.RaiseChangedEvents() +89
    System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2777

    Hi frJericho,
     
    Which line cause this issue? Can you post the full error information herer (or a screenshot)?
     
    Maybe you can refer to section "Store Files (images and documents) into a Database" in http://www.cutesoft.net/example/howto.aspx first.

    Here's the sceenshot of the error I get when the file is uploaded:
     
    Also, the link you have posted does not offer any help regarding a custom provider for the AJAX uploader. Please note that this situation is not related to saving images into a database. I already have a custom provider that allows me to save my images to a database and it's working fine. What I am trying to do is prevent the uploader from writing temporary files to the hard drive.
     
    I looked at CuteEditor.dll in .NET Reflector and found the following line of code is probably causing this problem:
     
    It looks like the FileBrowserPage class is assuming the temporary file is on disk and attempts to use a FileStream to read the content.

    Hi frJericho,
     
    Please do not use method GetTempFilePath() in your own provider.
     
    If allow, please send your own provider code to [email protected], I will check it and get back to you as soon as possible.

    Kenneth,
     
    I am not using GetTempFilePath in my custom provider. The code I showed you is from CuteEditor.dll I used .NET Reflector to investigate CuteSoft's source code and I discovered that CuteEditor has some code to load temprary files from disk. That's the source of this problem.
     
    Let me say it again to make sure I am 100% clear: there is code in the CuteEditor DLL that assumes temporary files are saved on disk and therefore prevent us from using a custom upload provider. The problem is not in my provider, the problem is in CuteEditor.dll. To be even more specific, I can tell you the problematic line of code in CuteEditor.dll is the following:
    The reason why this line of code is problematic is because it makes an assumption: it assumes that the temporary file is located on the server hard drive which is no true when we implement a custom upload provider. Therefore, this line of code fails with the error message I previously demonstrated.
     
    Hopefully this is clear now.

    Hi,
     
    That is a bug. We didn't expect the customer use that provider.
     
    We will update it as soon as possible.

    Terry, can you give me an update? Do you have a rough estimate when this will be resolved? This is important for me because I need to replace the UploadProvider to make sure that temporary files are not written to disk.
     
    Thanks

    Thanks.
     
    It would have been great to know when I asked what was included in the July 3 release.
     
    You guys need to figure out a better way to communicate what issues are resolved when you release a new version. As I have said before, you do a good job of promptly fixing issues that we report but you do no communicate very well.
