hello tech support,

i am trying to use your DMXzone components to upload a single image file and insert its name in our database. I am following this video tutorial.

www.dmxzone.com/go/32764/dmxzone-app-connect-manual/23315/upload-a-file-and-store-its-name-into-a-database

the db insert is working, the single file upload is not.

here is my test page:

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_04.asp

the console error message is:
POST 500 ( Internal Error )
dmxAppConnect.js:7

thanks
Glenn

Hello,
I see not errors on your page. Could you provide a screenshot of the exact error message please: prntscr.com/ktu8aa

hello Teodor,

thank you for helping me. here are some screenshots...

i am not sure how to use your reply tools for inserting screenshots, so i am providing links to the JPG on our server instead.

each JPG is a step in the process. when i opened the developer's console and click on the error, i'm taken to the "dmxAppConnect.js" file, line 7. i saved that information in a text file that i can email to you.

This is not proper file you are inspecting for error.
Open NETWORK tab in dev tools, click XHR and submit the form again. Then the asp file will show the error (500) click the asp file and check what is the error message exactly.

hello Teodor,

thank you for helping me.

here are the network screenshots. Each JPG is an XHR tab ( Headers, Preview, Response, Cookies and Timing ) for the SingleUpload asp file.

Hi Glenn,
Your third screenshot shows the error, returned by your server - maximum request length exceeded. - and this happens on files larger than a certain value.

This happens because in your server configuration this is limited. You must set the request size and file upload size on your server configuration to a larger value.

Hello Teodor,

thank you for helping us.

this is what i am thinking of asking our host provide ( rackspace ) to increase the sever setting to.

---------------------[ start ]--------------------------------------------

server WIN IIS 7 default configuration:
Maximum Requesting Entity Body Limit to 200000000

web.config file:
maxRequestLength = "102400000"
maxAllowedContentLength = "1024000000"

---------------------[ stop ]--------------------------------------------

does that look reasonable sizes to you?

the educational goal is for the images to be used in training courses and so should not be very big. we plan to add code to prevent that. right now, i just want to be able to upload the image.

thanks,
glenn

I still see the same error with larger images

Quote

message: "maximum request length exceeded"

Are you sure you set this for the right site and restarted server after setting it? It is really your server limiting this, there are no limits set in the extensions.

Hello Teodor,

here is a new link for testing, i am exposing more details on the page. hopefully, those details will help you spot the cause.

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_05.asp

I am seeing "200" on the dev's network tab ( in the broswer ) but the image file is not being uploaded. In the response, i am seeing the "upload1[ ]" but it looks empty.

our host ( rackspace ) increased the server's defaulty confirguration "Maximum Requstion Entity Body Limit to 200000000" but did not touch the web.config file. they did not see to two line items: "maxRequestLength" and "maxAllowedConstantLength".

they did not add them to the web.config file ( and so, did not set their limits ).

do they need to be web.config file for the Image Processor upload to work?

thank you for helping us.

thanks,
Glenn

Hello Glenn,
No these changes are not usually required for image processor - that is just some strange configuration on your server ... however whatever they changed seem to have fixed the issue with the upload. I see no errors now, so the image must be posted.
Please make sure to enable output option in the file upload step, so we can see what does this step return.

Hello Teodar,

yes, i agree. we are not getting that error now. however, the image file is still not being uploaded. the database insert still works.

here are links to new screenshots... i am exposing more details. also the output option has been enabled.

screen shot 2 seems to suggest that the upload2 array is empty...

thank you for helping us. i feel we are close, just something on the edge is not set right ( smile ).

thanks,
Glenn

Hello Teodar,

does this Response Header mean anything to you, in particular, the X-Powered By: ASP.NET?

Response Header:

Cache-Control: private
Content-Length:14
Content-Type:Application/json; Charset=utf-8
Date:Mon, 17 Sep 2018 19:01:06 GMT
Server:Microsoft-IIS/7.5
X-GeneratorMXzone Server Connect
X-Powered-By:ASP.NET

could that have something to do with the upload array being empty?

Preview:

{upload6: []}
upload6: []

thanks,
Glenn

I don't think you enabled the output option for the upload step in your server action, also please enable the Throw Errors option as well.
Please provide a screenshot of your server action steps, i don't need screenshots from your browser, as i see everything in my browser console.

Hello Teodar,

here are links to new screenshots... i am exposing more details. also the output and throw options are enabled.

www.trclink.com/banktrainingonline/courses_cb/images/screenShot_forDMXzone/gpwErrorMessage_dmxImageProcessor_02.jpg

when i test the page (and look at the dev next preview ) the upload array is empty...

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_05.asp

thanks,
Glenn

Hello Teodar,

fyi - you might have to clear your cache to get the two new images.

thanks,
glenn

Now as i see your screenshot - i see the error: prntscr.com/kvubvf

You selected a wrong expression for the upload step... it must be just the {{$_POST.file}} without "name" there ...

hello Teodor,

AWESOME, it worked.

thank you!

i still have to do some testing and refining but i feel we are moving forward again.

for now, let's keep this ticket open a little long.

thanks,
glenn

Hello Teodor,

i am trying to build upon my success with uploading a single file and inserting a record into the database.

for now, i am focused on uploading just one file at a time. I want to be able to "re-size" the uploaded file ( so that it is the right size for the course page ) and "create a thumbnail" file ( for use else where on our site by the course builder ), then "insert a record" into the database.

is this the right video for me to follow?

www.dmxzone.com/go/32469/dmxzone-image-processor-manual/32465/upload-resize-and-create-thumbnails

i tried it but failed. my upload and insert worked, but my attempt to "re-size" and "create a thumbnail" did not. also, the "overwrite" didn't work either. I got an error message, something like "file exists already".

is there a different video i should be following?

thanks,
glenn

Hello Teodor,

can you try this page... i have enabled "overwrite" and "throw errors". fyi, with this test page i am not inserting anything the database.

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_10.asp

the upload works ( as long as it doesn't have to overwrite anything), but the file "re-size" and "thumbnails" don't. there are plenty of error message in the dev console ( smile ) to work with and think about...

please point me in the right direction.

thanks,
glenn

I see one huge issue on your page - you are trying to follow some old tutorial which uses HTML 5 data bindings. HTML5 Data Bindings has been replaced by App Connect ... you must only be using App Connect (no html5 data bindingsgs, no server action executors etc.)
And currently on your page you have BOTH app connect and html5 data bindings which causes even more troubles.

hello Teodor,

ok, i will strip that code out ( and start a fresh )... no HTML 5 Data Bindings, just App Connect.

fingers crossed!

thanks,
glenn

hello Teodor,

It is ready for you to try, for me, the upload worked but not the "re-size" and "thumbnail"

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_10.asp

i'll upload some screen shots of the code.

thanks for helping me.

thanks,
glenn

hello Teodor,

here are updated screenshots of my settings...

Hi Glenn,
Everything is working almost great except for a small thing. Your page features a single upload file field, while the action file is expecting multiple file upload field, as you are using a repeat step after the upload.
The repeat step is only required when uploading multiple files. So either remove the repeat step, after the upload step and place the rest steps there, without a repeat or make your file upload field multiple (if you need to upload multiple files).

Hello Teodor,

can you try it now, the upload is working but the re-size and thumb nail actions are failing with the response pointing to a "Compilation Error - a resource is required to service this request"...

www.trclink.com/banktrainingonline/admin/cb_upload_JUNK_10.asp

i'll upload new screen shots of my setup soon. i removed the repeat region and unchecked the multiple.

thanks,
glenn

This is now related to your site setup in IIS:

1. The site folder should be in the root of an IIS application folder not i a subfolder. You can convert the folder to an application folder in IIS.
2. Make sure the Bin folder is in the root of the application folder.
