| Http.sys and TIWCGJQPDFViewer error: Atozed or CGDevTools? |
|

Hi,
TIWCGJQPDFViewer error message is: PDF.js v1.10.88 (build: c62a1938) Messagge: file origin does not match viewer's
when I use Indy it's ok, no errors.
When I use new http.sys the TIWCGJQPDFViewer does't find pdf file (see below why)
Test scenario:
Public port 3434 redirected on private port 3535 (intraweb app use 3535 port), on my public IP XXX.XXX.X
From a remote site open a browser session http://XXX.XXX.X:3434
UserSession
Code: function TIWUserSession.PreparePDF: string;
var ms : TMemoryStream;
begin
Result := TIWAppCache.NewTempFileName;
ms := TMemoryStream.Create;
try
ms.LoadFromFile('wwwroot/pdf/somePDFfile.pdf');
ms.SaveToFile( Result );
finally
ms.Free;
end;
Result := TIWAppCache.AddFileToCache(WebApplication, Result, TIWMimeTypes.GetAsString(mtPDF), IW.CacheStream.ctOneTime);
end;
MainForm
Code: procedure TIWForm1.IWCGJQButton1JQButtonOptionsClick(Sender: TObject; AParams: TStringList);
var pdfFName : string;
begin
pdfFName := ServerController.UserSession.PreparePDF;
with TiwFormPDFViewer.Create(WebApplication, pdfFName) do
Show;
end;
PDFViewerForm
Code: constructor TiwFormPDFViewer.Create(AOwner: TComponent; pdfFile : string; showPreview: boolean);
begin
inherited Create(AOwner);
IWCGJQPDFViewer1.JQPDFViewerOptions.PDFFileName := pdfFile;
end;
From the browser console (remember XXX.XXX.XXX.X is my public IP)
with Indy,
<iframe style="width:100%;height:100%;border:0;" src="/pdf/jq/pdf.js/web/viewer.pdfv?file=http%3A%2F%2FXXX.XXX.XXX.X%3A3434%2Fpdf%2F%24%2Ftemp%2FATZKckrBtj3fu~hbGXiCzjY-W"></iframe>
decoded URL: /pdf/jq/pdf.js/web/viewer.pdfv?file=http://XXX.XXX.XXX.X:3434/pdf/$/temp/ATZKckrBtj3fu~hbGXiCzjY-W
with Http.sys:
<iframe style="width:100%;height:100%;border:0;" src="/pdf/jq/pdf.js/web/viewer.pdfv?file=http%3A%2F%2FXXX.XXX.XXX.X%3A3535%2Fpdf%2F%24%2Ftemp%2FATZepIzsB8XUeYSw2FW6aToMG"></iframe>
decode URL: /pdf/jq/pdf.js/web/viewer.pdfv?file=http://XXX.XXX.XXX.X:3535/pdf/$/temp/ATZlW4ZM9l-U0sTMNVGxvk5Xa
3535 is the local port and obviusly the PDF viewer can't get pdf file (from a remote site must be used 3434 open port)
With Http.sys the url for the cache file is with same port of intraweb application (3535)
while with Indy the cache file is correctly build with requested port 3434
If I simply open my public port 3535 (without a redirect 3434->3535) all works as espected.
Sorry for long post but it's very complicated to explain
Alfredo.

Hi guys,
thanks to Pete d'Oronzio we have a very nice demo of new IWTreeView features, including full Async support.
https://github.com/Atozed/IntraWeb/edit/...eeViewDemo
* this demo requires IW 15.0.11+
Please be aware that this demo uses the standard built in images but they can be easily configured. Everything in this tree view can be customized, including:
- sub-captions of nodes, images of nodes and also plus/minus sign, font and background of nodes and children, transition effect, custom css classes (and styles) for each style used.

| Placeholder does not work IW15 |

Hello friends, I'm having a problem with IWDBEdit in the adminlte template with IW15. The placeholder is not working. I have already used the ExtraTagParams property in OnHTMLTag and have already tried it directly in the template. But in both cases it does not work, simply when rendering the placeholder is not rendered on the page.
Just to appear on IW14 did not have this problem. If anyone can give me a hand I appreciate it. Thank you.
Best regards
Wagner.

| Adding SSL/TLS to SMTP Email Sending |

Hi All,
I have been sending emails using SMTP and Indy for a while now, but only using port 25, as I have not added support for SSL/TLS. I think I have to add a TIdSSLIOHandlerSocketOpenSSL component, but I'm not sure of the properties I need to set to get this to work with
- Implicit SSL on port 465
- Explicit SSL (TLS) on port 587
Could someone tell what I need to do to get this to work? Thanks for any help.
Cheers
Paul

| Can you avoid phone number links in Edge? |
|

We have a web application where we display phone numbers for informational purposes. MS Edge can transform text containing a phone number into a link. When this occurs in a grid where we have "row click", the web page hangs if you click the phone number link, and you have to refresh the page to get it working again. Is there any way to avoid this?
Best regards

I would like to send an e-mail message from my intraweb application, composing it.
I'm using the mailto command with all the data needed for the message, and, for open it i use the webapplication.newwindow(), but, together with the message from the default mail client is opened another empty window too.
Is there a way for open only the mail client window with the mail message ?
Thank you.

| How to prevent a clickable cell in a grid refreshing the whole grid |
|

Hi,
It would seem that clicking on a clickable cell in a TIWGrid causes the whole Grid to get refreshed. How do I stop this occurring?
Here's how to see my issue:
- Create a standalone Intraweb applicattion
- Drop a TIWGrid onto the form
- Add this to the OnCreate of the Form
Code: procedure TIWForm1.IWAppFormCreate(Sender: TObject);
var
i : Integer;
begin
IWGrid1.RowCount := 100;
for i := 0 to IWGrid1.RowCount-1 do
begin
iwgrid1.Cell[ i, 0 ].Text := i.ToString;
iwgrid1.Cell[ i, 0 ].Clickable := TRUE;
end; { for i := Low to IWGrid1.RowCount-1 do }
end;
(NOTE: The only reason to add so many rows is so you get a scrollbar)
Now run the application and open the browser and scroll down to the bottom of the grid and then click on a cell. The grid will scroll back to the first row which to me makes me think it's been completely refreshed? I'd like for the grid to just stay where it was before I clicked on it.
Many thanks in anticipation.
Ian.
