Yesterday I started having issues with testing my Cosmos code. Whenever I click the "Cosmos" button at the top of Visual Studio, It goes through the normal build and debug procedure, but when VMWare starts, I don't see my OS(named 'Experiment One'). I see:

I downloaded Visual Studio 2019 last night(love it!) and got the user kit this morning(6-6-19). I completed a simple OS, tested in VMWare, and tried to make an ISO file to boot it from USB on an old laptop. I found that the documentation for this references many things which(I guess) no longer exist.

Hi, I'm attempting to show alternatively two modal dialogs using two TIWFrame and TIWModalWindows.

In IWAppFormCreate event I have added this code to create the frames:

 // Create first frame
 FFrameInput:=TIWFrameInput.Create(WebApplication);
 FFrameInput.Name:='FrameInput';
 FFrameInput.Top := 0;
 FFrameInput.Left := 0;
 FFrameInput.IWFrameRegion.Parent:=Self;
 FFrameInput.IWFrameRegion.Visible:=False;
 // Create second frame
 FFrameFilter:=TIWFrameFilter.Create(Self);
 FFrameFilter.Name:='FrameFilter';
 FFrameFilter.Top := 0;
 FFrameFilter.Left := 0;;
 FFrameFilter.IWFrameRegion.Parent:=Self;
 FFrameFilter.IWFrameRegion.Visible:=False;

Then I attempt to display the FFrameFilter using TIWModalWindows with this code when I press a button in main form:

      RenderInvisibleControls:=True;
      with IWModalWindow1 do
       begin
        Reset;
        Buttons.CommaText := '&Ok,&Cancel';
        Title := 'Filter';
        ContentElement :=FFrameFilter.IWFrameRegion;
        OnAsyncClick := FrameFiltroDoOnAsyncClick;
        Show;
       end;

But instead the FFrameFilter the system displays the other one, the FFrameInput !
I assign to ContentElement the FFFrameFilter.IWFrameRegion and it display the FFrameInput.IWFrameRegion !!!

If in IWAppFormCreate I remove the code for creating the FFrameInput leaving only this code:

 // Create only the second frame
 FFrameFilter:=TIWFrameFilter.Create(Self);
 FFrameFilter.Name:='FrameFilter';
 FFrameFilter.Top := 0;
 FFrameFilter.Left := 0;;
 FFrameFilter.IWFrameRegion.Parent:=Self;
 FFrameFilter.IWFrameRegion.Visible:=False;

the system display correctly the dialog...

How it's possible ? Any idea to solve the issue ?

Hi,

I need to fix money values of a IWDBEDIT before save it to a  firebird DB table.
I use a MaskMoney JS plugin to format the money entry data.
Alter I enter data, my front end shows for sample: "$ 10,00". Next, I call an AsyncClick  of a Button as:

Hi, all.  I have an IW10 stand-alone app packaged as a Windows service compiled with Delphi XE that continues to run great.  Except, that on one customer server (Win Server 2012 Datacenter) the service has begun crashing periodically.  The same .EXE doesn't seem to have this problem elsewhere.

In any case, the error logged in the Windows Event Log is Exception 0xc0000264 ... which pertains to critical section not owned.

I understand what that means, and am aware of fixes for some historical bugs.  (For example my project does use the IWRtlFix unit.)

I also understand that threading race conditions can be tricky, and can be masked until one day they appear.

So my question is:  Are there known Delphi or IW bugs discovered in the past few years that would impact IW10 on XE that are related to critical sections?

I've reviewed the code, and it seems to be OK.  But something (like a fairly recent Windows update) has caused the previously-stable service to crash.  This article seems relevant though:  https://docs.microsoft.com/en-us/windows...on-objects ...but that specific change was some time ago (before I began having problems).

Any ideas?

*** Problem Solved ***
Had to change <requestLimits maxAllowedContentLength /> setting in IIS



I created a simple ISAPI (.dll) and standalone (.exe) app with just a IWFileUploader on a blank form. I am not saving the file or have any events defined

I am getting error "UNKNOWN" when attempting to upload a file of size 39 meg when my intraweb app is run as ISAPI dll.

MaxFileSize is set to 90971520  (90 meg)

I can upload 19 meg file in both.

I can upload 39 meg file only in .exe app  ISAPI app shows uploading to 99% but then goes RED with hint saying "Unknown"

I have tried building in Delphi RIO with Intraweb 15.? and Delphi Tokyo 14.?

Is there a hard internal limit to the max size of a file that can be uploaded?

Howdy All!

Is there an easy way to get a value from a control via javascript? That is, I want to do something like:

bool bChecked =  ExecuteJavaScript("document.getElementById("myCheck").checked;");


Thanks in advance,

Hi,
I have an intraweb application that runs smooth under normal condition, but under fast demands it sends a "internal error 500" to the clients.

The error arises when using a custom handler (e.g. iw.content.xml look alike) after this is called rapidly (Called by an external program, 5 times typically). If the same operation is done one at the time (slow) there is no problem.

I suspect that it might be a memory error, but have no clues.

Is it possible to release the custom handler after use (freeing the memory) or is this done automatically by intraweb?

Will it help to insert a small time delay between each call?

Sorry if this is a bit "fluffy", but i have no idea where to set in for a solution

regards ib

I use Indy 5499. After installing and compiling it, first thing I noticed is that right clicking on dclIndyCore140.dpk and selecting Install reports an error. This wasn't the case in earlier versions, however, Install on dclIndyProtocols140.dpk works fine. I assume this is some change since earlier release and that it is now enough to install just dclIndyProtocols140.dpk

Anyway, onto the main problem - when downloading message list from IMAP, using UIDRetrieveAllEnvelopes

I get a list which contains subjects like (reply log from server):

Quote:* 1760 FETCH (UID 12777 FLAGS (\Seen) ENVELOPE ("5 May 2019 07:50:59 +0200" "Test \"quoted text\", more text" (("test" NIL "test" "test.com")) (("test" NIL "test" "test.com")) (("test" NIL "test" "test.com")) ((NIL NIL "test2" "test2.com")) NIL NIL NIL "<msgid@test.com>"))

I'm redesigning some IW forms using Bootstrap and I couldn't figure out yet how to reset the Tab Order. I assigned at design time a certain Tab Order for each form input in the old design and now, using Bootstrap the Tab Order needs to be changed. Being lazy (and in the same time wanting to keep the old design working), I'm trying to modify all the controls on all the forms in code, depending of what style I'm using and loading the corresponding template for each style. I tried setting Tab Order to 0 and to -1 when I load the BS design, but it seems that the old Tab Order is still there, any idea why and how to fix this?

Here is my code that deals with changing the components style at run time:
