By default the (Client) IOHandler.ReadTimeout is set to -1.

What does this mean if it is not changed?  Is it internally setting another default, or wil it not time out at all, and keep waiting?

I have a situation where a ReadTimeout occurs all the time with the default settings, and the Client loops. I have no idea after how much time it actually times out.

I am tryng to use the CGJQPDFViewer to view a PDF file from the Cache folder.

I am copying the file to the Cache and setting the  

I get the error in the PDF viewer :

Message: Missing PDF "http://127.0.0.1:8888/$/MyApp/zHOG5EAdJuoVjqQJqQUg9W/EXP_20170525_583001.pdf?cache=1731781782136".

The file acually does exist in the temporary cache folder ???? I even test that it exists before I assign the value

s1 := WebApplication.UserCacheDir+ExtractFileName(UserSession.qry1DocFile.Value);
s2 := webapplication.UserCacheUrlBase+ExtractFileName(UserSession.qry1DocFile.Value);


  if fileexists( s1)then
      PDFv1.JQPDFViewerOptions.PDFFileName:= s2;

Hi there - I'm (still) using CPB XE7 with IW 15.0.22, no question of updating.

I need to present some data in a table for which in CPB I use a TListView.  I need to set the background colour of each line according to the context of the line's data.  I chose TListView because tweeking the colour is easy, I simply use OnCustomDrawSubItem, extract the context from the data, and apply the colour:

if ( adlt == 'A' )
lv->Canvas->Brush->Color = (TColor)nA_COLOUR;
else if ( adlt == 'D' )
lv->Canvas->Brush->Color = (TColor)nD_COLOUR;


Easy as that!

In the web version I can format the text presentation as required (eg using sprintf to prepare a complete line) but I can't see if there is a list component that will allow me to set the colour ?

Many thanks for any advice.

Denville.

Hello,

Our application uses a ProgressIndicator on asynchronous events but it shows the busy icon after a very short time, for example if a user clicks a button and the response is immediate the locker appears anyway and this is annoying for user experience. It's possible to extend the time before the icon appears? 

Thank you very much.

Can I not have an application without forms or sessions, with content handlers only? - it gives me "Session has no active form". Maybe I'm just missing some setting somewhere?

I just have this:

  with THandlers.Add('', '*', TXXXX.Create) do begin
    CanStartSession := False;
    RequiresSessionStart := False;
  end;


I can probably do this in the OnExecuteRequest instead, and just as well, I just never expected handler-only approach to fail...

The error has no session ID. But it does mention a single cookie. And it's a POST - IW trying to establish a session after the initial GET.

Error details:

Does IntraWeb provide for a way to add/change browser request headers on a redirect? - I know that it's a security issue and was not traditionally possible, but apparently some such things can now be done with service workers. If there's already some plumbing for this in IW, then it would save me a lot of time. Would also be nice to know the rules: what can and cannot be done in what cases.

There are many examples of the reverse, but none that gives you ability to call a JS function on a page from Pascal. Is it possible?

For instance, I want to submit a form. Which I have just dynamically created on the page.

I know that if I add some OnLoad JS somewhere and click some button synchronously, it would re-render the form, execute that OnLoad function and this can submit my form, but I'm trying to avoid reloading the form, I want the buttons to work asynchronously, so there will be no reload and any OnLoad events there would not fire.

Without a lot of doco, everything becomes a problem. If these questions are already covered anywhere, can someone please point me there? -

1) I can see a new session created on every new request to a content handler, but at the same time, no cookie is being set. I would have thought the IW cookie should be set automatically to match the Session, so if a content handler is called 1,000 times, it would not leave 1,000 sessions behind. I'm creating content handlers with:
          CanStartSession := True;
          RequiresSessionStart := False;

Are there any tricks to it, or would session handling need to be coded from scratch, if needed? Because without this, what good are these ephemeral sessions anyway?

2) Also. can a handler be defined for a wildcard path, like /do/*? - to respond on both /do/this and /do/that?

Or defined for /do, so that requests for /do/something trigger it? - because from what I see, it's not happening.

Or can content handlers be released and recreated at runtime, i.e.: in a form event? - because I need to listen on a number of configurable paths, which may change from time to time and I would not want to restart the service every time this list changes.

3) There're AddRootHandler & AddStartHandler methods there as well. What do they do / what are they for?

I have a frame which I am displaying on four pages of a TIWTabControl. The four TIWTabPage pages are created dynamically, and as each one is created an instance of the frame is created and assigned to the page by setting its parent. There are some components such as TIWButtons on the frame and everything up to this point works perfectly.

I need to add a TIWGrid to the frame. I can place one on the frame in design time and it works but I can only update the grid on the first tab page. I figured out that this was because each instance of the grid must have a unique name. I tried setting the name in the IWFrameRegion create event but that did not work. It resulted in access violations.

So I then decided to create the grid dynamically, again in the IWFrameRegionCreate, and assign a unique name to each grid. This was partially successful.

Is this something that is currently supported, downloaded the latest source after coming across AV's with this SASL processing and it looks like this is not enabled?
