| Scale application to screen |

What is the best practice to scale a form/application to the browser's screen size? I've looked and tried examples of Bootstrap, but the component selection is limited and I was not successful in modifying the examples to my need. All I really need to do is display a text message in a color and size of my choosing nicely in the center of the screen, be it iPhone, android, tablet, or laptop. Thanks.

| Session is already locked - Causes instability |

One of our senior developers is working on an Intraweb app which we are trialing with around 2000 end users per day. On occasions, the handled exception shown below is raised. This would be fine however it leads to approximately 20% of users experiencing a continual timeout waiting on the return of any callback submissions.
It is important to note it is not all users, or just ones connected after the event that is affected and it always follows on from one of these exceptions.
It would appear it is from the aSync Callback taking time to complete on a slow connection so the button does not disable quickly enough and though the process lock is in place for the callback if they click it enough before it disables the button then it raises the Exception.
We have worked around this by adding in an onClick javascript setting 'disabled = true' by directly referencing the button within the DOM, thus client-side. This is just a little labor-intensive and I would have expected it to be experienced by others. The callback is a aSync event and not just a form submission as we have to ensure that certain data is processed before submitting.
As such my questions would simply be:
1) Why does the Exception then affect a percentage of other users and make the platform unstable?
2) Is it possible within Intraweb to automatically force a client-side disable of buttons without having to manually create the javascript to disable or is the technology always designed to be server-side via the aSync callbacks?
3) As we are still getting the error (I assume by the user refreshing via the command line) is there any way to ensure it does not affect others.
Thank you in advance for sharing your thoughts.

| Service stuck at Starting |
|

I have a Standalone Application (Indy) that runs fine when compiled as an application but when compiled as a service (TIWStart.Execute(False); ) the service starts, the IWServerControllerBaseConfig runs and exits, the IWServerControllerBaseCreate runs and exits. There are timers on the form and they run and execute, but the Service never shows in the service manager as Running, only sits at Starting, and browser connections cannot be made to the service. Any ideas? What has to finish for the service to be "started"?
BTW, This was an update to a service that has been in operational use for 5 years. It is to be version 2.3 but this is the first time I have had this issue. I made updates but can't figure out what could be causing it - and when I disable some changes or replace the items with what was used before it still happens. I can compile version 2.2 with the new Intraweb and it runs as a service fine, so it isn't an Intraweb issue. I just don't know what to look for that would cause it to not tell Windows it was loaded but that doesn't cause an issue when compiled and run as an app.
Thanks
David

Olá Pessoal,
Sou nova no intraweb por isso já antecipo a falta de conhecimento, eis meu problema:
Fiz uma tabela usando html para montar o cabeçalho e chamei o restante pela procedure TemplatesUnknownTag, e ainda usei uma função em jscript usando a jquery que faz com que seja possível editar os dados diretamente na tabela "salvando" as alterações com o clique do Enter não uso nenhum edit e nem button no delphi para fazer essa edição, porém agora não sei exatamente como fazer para o delphi receber as alterações e fazer os updates no banco, pensei em usar algum evento da iwdbgrid, como onHTMLtag ou onRenderCell, porém não achei nenhum documento que explicasse bem como funciona esses eventos, assim venho aqui pedir uma luz!
Agradeço a oportunidade e aguardo um retorno!
