Oracle forms10g shows blank page - oracle

I Installed Oracle forms 10g on windows7 and created a sample form . Then I start up OC4J and run the form.
What I get is a blank screen. The URL is http://user-pc:8889/forms/frmservlet
Notice that the form name is not part of the URL.
thnks

Unfortunately there could be a number of reasons why the blank screen is shown and trying to identify the problem and correct it can be difficult if not impossible without accessing your PC!
My advice is to look at similar problems on the Forms Forum on Oracle Technology Network which can be found here.
The first search results I found reporting a similar problem can be found here.
Good luck.

Any clue for crash report 'String - Couldn't download or retreive file.' got from Sentry - Flutter App?

One of my Flutter app on store an that app is integrated with Sentry client for crash reporting.
I got a few crashes and I have fixed most of them based on logs it provides and all I can say Sentry is one of the good solutions for the crash reporting in Flutter.
Unfortunately, I have one crash(Many users are facing it currently) there but I can't able to figure out what it is all about and what should I do to close that issue.
Here is just an overview of an issue and same in the details nothing much on EXCEPTION like stack-trace or so.
Here is the public share-able link for the same.
Anyone has faced similar kind of issue or any clues which can help me to get direction here?
Doing some searching for this, I have found that this is caused by CachedNetworkImageProvider.
In my case, the issue seems to be related to flutter_map and it is raised here: https://github.com/johnpryan/flutter_map/issues/245 - there is also a video link on how to fix this apparently (not sure).
I've also seen this raised in production a few times with very little other information. (The incorrect spelling of retrieve, means it's a bit easier to search for where this issue happens).

Visual Studio not finding my DB as data connection

I'm a newbie to programming, I'm trying to make a basic program which will write to a database, so I'm trying to follow Microsoft's own example here. I've created the sample database OK but I'm struggling with the "Create the data source" part. Firstly, the link about installing sample databases doesn't seem to actually have any information about sampling databases, so that's not a good start.
I tried to proceed with adding a data connection to the database but there's nothing in the dropdown when I try to choose a dataset.
I have the Azure Storage Emulator cmd prompt running and I've initialised to my MSSQLLocalDb but the 'start' command doesn't work. Can anybody tell me what I'm doing wrong??
Thanks in advance.
but I'm struggling with the "Create the data source" part.
I also follow the example that you mentioned. If we add the server (localdb)\MSSQLLocalDB for the server name then we could see the databases listed in the dropdwonlist.
For more information you could refer the screenshot.
Then click next and choose the tables, we could get the expected result.

Oracle Forms 10g or 11g for users with limited vision

I want to know, how to make Oracle Forms 10g or 11g more accessible to people with disabilities. For starters, is Oracle Forms compatible with web browser zoom level, if not, is there some way to dynamically change size of Forms items? I tried to search in the internet, but there is so little information about that.
You can try the ClientDPI parameter in webforms.cfg
I've used it to fix form size (you could say "zoom level") on linux and mac clients. It's not user configurable, but you could offer your users several zoom options through the calling url
Check this out: http://docs.oracle.com/cd/E15523_01/web.1111/e10240/configure.htm
Hope it helps.
This works like a charm: https://discussions.apple.com/thread/8563562
i did not have to install the browser in mention, i used an old mozilla firefox version and looks nice and crispy..ttthe key is the script's terminal.
i changed the clientDPI too to adjunt the size a little.

Why did ABCPdf code start generating a Window Error 5

I have had some long standing code which has worked fine for quite some time. Recently it began generating the following error. 1st on a asp site and later on a .Net MVC site. Neither of which have changed. I really curious as to why the this error now is rising. I am hoping this post will be of use to someone in the future since the solution was difficult to find searching the error itself.
Error:
ABCpdf error '80070000'
Unable to render HTML. Unable to get printer device-mode size. Microsoft XPS Document Writer Windows error 5. Access is denied.
Some research suggest that it is because the xps writer is not installed but this was not the case or that permissions were set up incorrectly.
http://www.websupergoo.com/support.htm# Support issue 6.7 number 4. Add the line below to the object and it worked.
Doc.SetInfo(0, "HostWebBrowser", "0");
This did the trick in both cases.
Just FYI, I think the ABCPdf 8.1 release addressed this issue.
Have you got the new version of ABCpdf 8?
As with older versions they use the IE rendering engine, if you upgrade the server/machine which is running ABCpdf to IE8 or higher abc pdf no longer have access to the rendering engine and will produce some very very odd results.
With 8 and above I have found the most consistence rendering is gained by changing the rendering engine used
theDoc.HtmlOptions.Engine = EngineType.Gecko;
this means youi are also not using IE which can only be a good thing.
We had this issue at work after some server updates. I resolved the problem by going to printers on the server and deleting the Microsoft XPS printer.
As soon as it was removed our PDF rendering came back!
Hope this helps!

Web Performance

Im working on a large site, trying to decrease the load times, and I have bumped into a rather strange issue. Im using google chromes built in developer tools, and I am finding that certain images are getting hung up, and the browser is continuing to look for them. Has anyone encountered this issue before? How do I isolate what is causing this problem?
The site runs a couple of ads, is it possible this error is occurring because of ad networks?
Here is a link to the actual problem: http://i.stack.imgur.com/IEtLA.png (updated)
If you have not done already, use a tool like http://www.webpagetest.org/ to test your site. It will test the site from nominated locations around the world, with the browser of your choice, and you will get waterfall charts for your page.
Just an idea.... If not yet done, try Google's free website testing and optimization tool 'Website Optimizer'. See what it tells you.
Another idea, try accessing the site with another browser, either one, IE, Safari, or FireFox, to see if you get the same issue; if you do then it may be the server for some reason not serving those images.
One more.... To isolate further, if possible, try using only few (one or two) images in your site/pages; if these load then add one or two more images until you encounter the issue, then that image has something and you may replace that image.
