  Tab order issues mixing CG and IW components
Posted by: bob9999 - Yesterday, 04:25 PM - Forum: IntraWeb General Discussion - No Replies

Hi there.  I searched through and found other threads on this subject but nothing that really assists my situation.

I have Delphi 10.2.3 and IW15.1.7 installed.  In the designer I set the CG and IW tabs to the order I want but at run-time, there seems to be an order of CG and an order of IW that can be a bit random at times and pressing the tab at run time jumps around on the screen depending on the mix of field types.

In the designer or IDE, when I go into tab order, only CG fields are listed in this and never IW.  This appears to be the issue.  Is there a way to turn on the tab order in the designer for IW components so then the mix of components at run-time are rendered in the correct order?

If I have a region that is only CG or only IW, then all is fine at run-time and I can tab from field to field in the order I have set in tab order.  Only in a mix of field types does this odd issue surface.

I am just questioning here in this forum since I cannot get the IW components to list in the taborder tool in the IDE suggesting an IW issue.  I have worked around the issue for a while but the client noticed now for an area that I cannot work around and have to resolve this issue now.

  Manual Delphi Bundled Registration
Posted by: jack.k.rappold.civ@mail.mil - Yesterday, 01:11 PM - Forum: IntraWeb General Discussion - Replies (3)

I have tried to run the app you provide for getting a Delphi Ent Bundled Intraweb registration but my computer is locked down and won't let me.

It seems to need some sort of code or information from the local Delphi Installation that if I don't run it on the Delphi computer, it can't see.

Is there a manual workaround? Huh

  Intraweb Service and EurekaLog
Posted by: tinygoldwing - 01-21-2020, 10:48 PM - Forum: IntraWeb General Discussion - Replies (1)

I have an Intraweb standalone app.  I followed the instructions to get Eurekalog to work.    When I run the app on the desktop I actually get the lines where I created a AV:

(00B42D78){Project1.exe} [00F43D78] Unit1.Tfrm_Main.IWButton12Click (Line 668, "Unit1.pas" + 3) + $8

But when I run it as a service it only gives me:

(00550487){WebApp.exe  } [00951487] Unknown function at TMethodImplementationIntercept + $4E3BBB

Does anyone know what I missed.  I know there is a special setup.  I did ask Eurekalog but I haven't received a reply.

Thank You,

  Weird session form overlay issue and memory leaks
Posted by: bob9999 - 01-21-2020, 09:54 PM - Forum: IntraWeb General Discussion - Replies (1)

Hi there.  I have a really weird thing occurring in my project (IW15.1.7) that I wanted to post here to see if there is something wrong in the way the session state is kept or something I need to use a different approach or command for.

The form that I have been able to replicate the issue with is an AsyncClick event off of a IWImageButton.  The form blinks and is like the form is reloaded.  Then when I click on the button again, the new form is loaded (that is all this button is doing is just loading a new form) but the old form stays on the screen and the new one displays as well.  All components are active and needless to say this is all rather confusing.  Then I click on the refresh button and then the new form reloads without the old form there.  

The other situation that is occurring that I cannot recreate (user just keeps running into this and complaining) is that I am on an existing customer form and all seems OK.  Then I click on a button the same way (except this button is just a IWButton) and the new form loads 100%.  Then when I click on the new customer button, this original form loads but will keep fields filled in rather than being blank from the beginning form that was loaded that started this situation.  I tried to initialize the fields programatically just in case and in design the fields are all blank of course.  I have traced all logic paths and cannot seem to find the issue so I am thinking something is occurring in the session layer like the situation above.

Situation 1 is like the async event is uninterrupted and the same form is just stuck.  Then when click the button again it then overlays over the previous form instead of loading sovereign

Situation 2 seems to be that the form is not loading sovereign and has an image from the last time it was loaded.  I am going to review the data feed just in case but why would the fields still be displaying data when they are loaded fresh like this?  

The way I load new forms is:

So the old form should be released from session and memory but somehow there is a shadow kept from before.  By the way, I have not posted this issue yet but there seems to be some sort of memory leak over time and I suspect this release command is not 100% releasing forms from memory.  Over time my service gets too high in RAM usage and I have to restart the service.

  TIWTreeView SelectedItemStyle
Posted by: JuergenS - 01-19-2020, 05:16 PM - Forum: IntraWeb General Discussion - No Replies


I correctly set the background color and the font color in the SelectedItemStyle property in a TIWTreeView.
For active and passive nodes with different font colors, I set the different font colors in the TIWTreeViewItems and not globally in the TIWTreeView.

When selecting a node, however, only the background color of the selected node is switched, NOT the font color!

C++Builder 10.3.3

  New demo: New IWDBLookupComboBox features
Posted by: Alexandre Machado - 01-18-2020, 10:45 PM - Forum: IntraWeb General Discussion - No Replies

In IW 15.1.11 we introduced 2 new properties in IWDBLookupComboBox and IWDBLookupListBox controls.

From the release notes:

Quote:DBLookupComboBox and DBLookupListBox new feature AutoSetListSourceCursor.

Allows automatic refresh/sync of DBLookupComboBoxes/ListBoxes when lookup DataSets are part of Master/Detail relationship

Here is an online demo showing how it works:


This is the "gigantic" amount of code required to make this demo work (source in our github repo, link in the demo):

unit Unit61;


  Classes, SysUtils, IWAppForm, IWApplication, IWColor, IWTypes, Data.DB,
  IWCompLabel, Vcl.Controls, IWVCLBaseControl, IWBaseControl, IWBaseHTMLControl,
  IWControl, IWCompListbox, IWDBStdCtrls, IWCompGrids, IWDBGrids, IWCompButton,
  IWCompText, IWHTMLControls;

  TIWForm61 = class(TIWAppForm)
    cbCountry: TIWDBLookupComboBox;
    lblCountry: TIWLabel;
    cbState: TIWDBLookupComboBox;
    lblState: TIWLabel;
    cbCity: TIWDBLookupComboBox;
    lblCity: TIWLabel;
    IWText1: TIWText;


{$R *.dfm}




yes, there is no code other than code created by IntraWeb application wizard itself when a new project is created.

Absolutely ZERO lines of code!

  New demo: IWGrid + DataTables (and almost no code)
Posted by: Alexandre Machado - 01-18-2020, 10:21 PM - Forum: IntraWeb General Discussion - No Replies


We've been asked to create a demo showing how to use a IWGrid with DataTables (http://datatables.net). So here is the online version:


Souce code in our git hub demo repo (link in the online demo)

Please notice that there is almost no code. All code is basically loading the grid from any data source (in that case we load it from a ClientDataSet, but it could be from any source, of course).

The server hosting this demo itself shows another interesting feature of how IW http.sys applications work: Several IW applications running as independent services using the same port (80). (you can see another demo app running in http://intraweb.net.br/ImageButtons/ )

  TTIWMainMenu (a TMS Intraweb Components control) and IW 15.1.6 +
Posted by: Fabrizio Conti - 01-17-2020, 03:21 PM - Forum: IntraWeb General Discussion - No Replies

I have a problem with a TMS Software control (TTIWMainMenu)

Starting from IW 15.1.6 TTIWMainMenu doesn't work in my applications.
I usually place a TTIWMainMenu in a frame that I insert in a form whenever I need it. It is very convenient and easy to maintain.

What happens is that TTIWMainMenu lost all the display settings (font, color, etc) and doesn't fire the OnAsyncMenuClick event.

Creating a new clean project I found that  TTIWMainMenu works as usual if placed directly in the form, but not in a frame.

TMS suggested to post the problem in the Intraweb Forum because they didn't change the control.
