I've gotten 'Could not load image' a couple of times now on two separate components.  One on TUIWAdvWebGrid.Glyphs.EditButton (which I've never defined) and now the TWIAdvImage1.Picture.  Since they are on the main form the app fails to load with that message.

Error details:

Exception message : Error reading TIWAdvImage1.Picture.Data: Could not load image. Invalid format
Depending on the error condition, it might be possible to restart the application.
Exception class : EReadError
Exception address : 004C60D0
Exception Time : 2019-12-07 17:41:47.445

I know these aren't your components but I started getting the message when I added a background image on form.background

It takes a while for the message to show up.  Usually in three or four days.  But once it does I have to restart the IW service.  I'm thinking maybe something isn't being released.  I don't know.

Please let me know if you've seen this.

Thanks,
Ed

I need the user to be able to select the area of the uploaded image like this,
https://zara4.com/projects/crop-select-js/example-01
which the image will be processed later. Preferably as an intraweb build-in method.
It it is not possible, I would need some help for intraweb to get input from java script library

Hi guys,

I have a grid on a form, and when the user resizes the form, I want to resize individual columns in the grid. I catch the resize and set the number of pixels to adjust Column width by, in the Forms OnAsyncResize, but the size of the grid is not changed. I suppose it is because I use OnAsyncResize. However, the OnResize is not fired when I resize the form by pulling it.

I have tried Grid.invalidate and Grid.Update but not luck.

Does anyone have any ideas of what I could try ?

Regards
Soren

I have seen an old thread which talked about the possibility of upgrading the jQuery version in IntraWeb 14 but can you please provide instructions on how to do so in 15?  I wasn't 100% clear on how to do that in 14 and was hoping there was an easier way in 15.  We currently have the default values in ServerController for JavaScriptOptions set (only RenderjQuery is set to True).  Our application has failed a penetration test due to vulnerabilities that apparently exist in jQuery version 1.12.4.  Please advise.  Thanks.

I am using the Intraweb version included in Delphi 10.3.1 to make a stand alone Windows 32-bit app.  I did get the updated version from atozed.

I'm not trying anything real fancy yet.  Mostly taking it out for a test drive.

I am trying to figure out how to set the <title></title> in the app so it shows in the browser tab instead of the web address. 

Any help would be appreciated.

Hi,

Can someone help me explaining following properties:
LockSessionTimeout
RestartExpiredSession
UniqueURL

Hi se below:

The error is:
Exception message  : FDQryWWD: Field 'RowID' not found
Depending on the error condition, it might be possible to restart the application.

From the trace you can see that the error is in Exception message  : Wwd.TfrmWWD.SRGridAfterGotoLink (Line 2555, "Wwd.pas" + 3) + $1B

Here you can see the code in my program:

procedure TfrmWWD.SRGridAfterGotoLink(Sender: TObject; RowIndex, ColumnIndex: Integer);
begin
  if (ColumnIndex = 20) then begin
//    UserSession.RowID := SRGrid.DataSource.DataSet.FieldByName('RowID').AsString;
    UserSession.RowID := UserSession.FDQryWWD.FieldByName('RowID').AsString;
    UserSession.NewFunction := 1000;
    frmTop1.GetFormName(UserSession.NewFunction);
    frmTop1.LinkTo;
  end;
end;


How is it possible that the field RowId sometimes just is not there? It should be impossible.

Hi,

Can I set ServerController.SessionTimout to be User specific?

Mikael

My desktop app works OK, but when I tried to move the code to intraweb I got many errors, "unknown identifiers"
"canvas has no brush class"

starting from
napis.PixelFormat:= pf24bit; "property is read only"

intraweb 15.1.5 delphi xe7

uses
FMX.graphics;

var
napis:= TBitmap;

napis:= TBitmap.Create;
napis.PixelFormat:= pf24bit;
napis.Canvas.Brush.Color := RGB(50,50,50);
napis.Canvas.Brush.Style := bsSolid;
napis.Width:= zdjęcie.Width;
napis.Height:= zdjęcie.Height;

napis.Canvas.Font.Quality:= fqAntialiased;
