I have a single form and many frames that descend from TIWFrame:

TIWFrame->TIWFrameBase
TIWFrame->TIWFrameBase->TIWFrameGRID
TIWFrame->TIWFrameBase->TIWFrameCRUD

TIWFrameBase includes some new properties and a few IW components
TIWFrameGRID includes ado dataset grid, controls, buttons
TIWFrameCRUD includes ado dataset, edit controls, buttons

and would like to store these varying TIWFrames in a collection where they can be
retrieved as needed.  The program will know the index of the desired frame and it will know the desired frame's type. 

My initial thought was to create an array of TIWFrameBase, but complained when I tried to insert a TIWFrameGRID into the array. 

My gut tells me that this should be super simple and I'm a little ticked off I can't figure it out, even with Google.

TIA for your help.

Using: Delphi 10.2.3

I've downloaded, built and installed the latest Indy VCL sources from repository and installed in a custom folder location. Prior to doing this, I uninstalled existing Indy components and deleted existing bpl, dcu and dcp files that came with Indy as part of the Delphi distribution. However now when starting the IDE, its showing error messages. One of these errors is:

Hello,

Developing an app where users may be in different time zones. In past I never worried about this as system date time stamps matched local time of users.    Now I am looking at  using   Postgres datetime type with time zone support  and need best option for ensuring I have the correct local session time.   Assuming all time is saved as  UTC .

To make maters more interesting it could be case where   driver leaves pt A at  5AM Pacific Time and gets to location at  6PM Pacific time  ( 6 PM Mountain Time) as it crossed a time zone.  The initial  user makes all entries based on   Pacific Time.

User at destination looks at system,  the time would then display for him i mountain time (his local time zone).

Should I set time zone based on setting in user profile or should I get it from the browser setting and have it be dynamic to allow mobile devices to work if user is mobile and goes between timezones. I have some sample code that I will update this ticket with to show what app currently does , but find that it sometimes does not work as desired.


Cheers!

Hello,

We have developed a thread-based TCPServer-application running on company machine (Windows 7) with fixed IP and fixed Port.
We also developed a standalone TCPClient application distributed to our customers.
We are now planning to change this Client-Server model to use SSL encryption (a server certificate does exist).

Can you please point me to some sample code how to implement SSL on server and on client  side.

Thanks in advance,
Wolfgang

Hello,

could you please help me on how to iterate over all forms included in the application.

This is a continuation of a thread at Embarcadero forum, which no longer responds to my input...


Background:
I have programmed an embedded IoT device (ESP8266) for which I have created a configuration application using FPC/Lazarus with Indylaz (Indy 10).
All of this works fine after some help from Remy L.
But there is one thing I also want to incorporate in the config application and this is firmware update via the network of the IoT device.
The ESP8266 has libraries with a lot of functions including web firmware updating, which I have included in my system.
It works as a simple web server operating on the http port of the IoT device, one simply opens the URI http://<ip address of IoT>/firmware and a minimal form is presented where there are two buttons, one file select button to select which firmware file to use and an Update button which starts the firmware update process.

The form presented by the IoT device on the URI shown above has the following html source:

Hello,

Can someone help me implement these functions (in Delphi XE4)


function Base64EncodeBytes(Input: TBytes): TBytes;
function Base64DecodeBytes(Input: TBytes): TBytes;

Could be using Indy or Soap.EncdDecd.

Thank you

Hi Guys, I've developed an application that uses Style Sheets, each form has the same CSS file and each component has it's CSS property set to an entry in the CSS file.

All works brilliantly in Chrome, Firefox & Opera but Internet Explorer just won't play ball and doesn't seem to apply anything from the CSS file.  My experience of CSS/HTML is limited and I guess IE doesn't like something in my CSS.

Any ideas or pointers would be much appreciated, I'm pulling my hair out.

Thanks

First of all, thanks for the new forum. It is unclear whether the community.embarcardero.com is a replacement for forums.embarcardero.com but all I see is that community is working and forums is not. Anyway, onto the possible bug.

In the example:

Quote:with TIdMessageBuilderHtml.Create do
try
PlainText.Text := 'plain text goes here';
FillMessage(IdMessage1);
finally
Free;
end;

Quote:Content-Type: text/plain; charset=us-ascii

plain text goes here

Quote:with TIdMessageBuilderHtml.Create do
try
PlainText.Text := 'äüø';
FillMessage(IdMessage1);
finally
Free;
end;

Quote:Content-Type: text/plain; charset=utf-8

äüø

This my "prototype" of Ocelot using Codepage 437 to do "graphic" in text mode:
