Use TeeChart in an IntraWeb application

[Lenfors]

Hello!

It is stated that TeeChart could be used together with IntraWeb!? I tried it but can't find any TeeChart component that can be added to an IntraWeb page?

My IntraWeb version is 15.2.21 and TeeChart version is PRO v2020.31.201112 32 bit VCL

Best regards, Mikael

I am using Rad Studio 11.1 and IntraWeb 15.2.52 (which are all the newest version).
I just bought the TeeChart Standard license and tried to use it in my IntraWeb Project using C++ Builder.
I initiate a blank IntraWeb project and just put an IWLabel on the main form.
Then I put a TChart on it and build the project.
After running it, I can only saw the label.
No chart can be displayed on the rendered html page.
Is there anything wrong?

Hello,

You need to load the supporting TeeChart package for Intraweb. YOu can download the most recent one here and update the references for your version of RAD Studio/Intraweb. See the readme.txt.

hello Marc

it seems that the most recently package in the url u gave to me (https://www.steema.com/downloads/vcl)
is only for Rad Studio 10.1 Berlin and IntraWeb 14 which might be too old for Rad Studio 11.1.

I found another url at another post (https://www.steema.com/support/download ... hp?id=8003) where TeeChart 2020 for IntraWeb 15 and Rad Studio 10.4 could be found.

But, since I am using Rad Studio 11.1 and IntraWeb 15, it failed when I tried to compile it and also fail to install.
Is there any adjustment needed before I tried to use it in Rad Studio 11.1 with IntraWeb 15.2.54?

Thanks for your instruction.

dear Yeray:

I followed the readme.txt decompressed from the zip file you gave and tried to compile the IW150TeeChart9_280 packages firstly.
But got the following error message.

[dcc32 Error] IW150TeeChart9_280_11.dpk(39): E2029 'END' expected but identifier 'Tee9280' found

I wonder is Tee9280 not the original Tee Std package shipped with Rad Studio?

Ihave installed the most recently TeeChartVCLFMXStandard-2022.35.exe where the Std package shipped with Rad Studio shall be backup to another folder already during installation process.

How can this error happened?

Please help to solve the problem.
Thanks again.

Hello,

The Pro packages would probably work for you but I've made new ones separated in 3 folders (Pro, Std, and StdCom) for more clarity. Note the "Std" packages are for TeeChart Standard/Lite shipped with the IDE, while the "StdCom" packages are for TeeChart Standard Commercial version.

dear Yeray：

Thanks very much.
This time, the newest update using Std Com seems to be great!
I compiled it and installed it successfully.
In the IDE menu:Component -> Install Packages, I can find out that TeeChart 2022 for Intraweb 15 had been installed well.
But strangely, I can't find the TIWChart Icon in the Tool Palette if I open a blank Intraweb Form.
Also, I tried to load the TeeChart9Intraweb15Example from the decompressed zip file you gave me.
There will be an error message when compiling:
[dcc32 Fatal Error] UnitChart9Intraweb15.pas(7): F2613 Unit 'IWCompTeeChart' not found.

Can you help me again to solve this?
I feel that it is one step to successful building IntraWeb with TeeChart.

Thanks a lot.

Hello,

There will be an error message when compiling:
[dcc32 Fatal Error] UnitChart9Intraweb15.pas(7): F2613 Unit 'IWCompTeeChart' not found.

You need to add the folder where you uncompressed the zip to the "Library path" so the compiler can find the IWCompTeeChart unit.

dear Yeray:

Thanks again.
The error was solved after I included the folder into the library folder according to your instruction.
And I also found that why I can't see the IIWChart Icon in the toolpalette.
That is because I am using C++ Builder instead of Delphi.
It seems that if I want to leverage Teechart for IntraWeb, I have to shift my development from C++ to Pascal.
Well...ok..but after fixed the previos DCC32 fatal error UnitChart9Intraweb15.pas(7): F2613 Unit 'IWCompTeeChart' not found.
I met another error as the following...

[dcc32 Error] IWCompTeeChart.pas(31): E2003 Undeclared identifier: 'TCustomChart'
[dcc32 Error] IWCompTeeChart.pas(32): E2005 'TCustomChart' is not a type identifier
[dcc32 Error] IWCompTeeChart.pas(41): E2005 'TCustomChart' is not a type identifier
.....

It seems that compiler missed the unit TCustomChart?

Can you help to solve the error again?
(The error came from when I tried to load the example project unzip from the file you gave to me.)

Hello,

Check "Generate all C++Builder files (including package libs)" for both packages and the TIWChart component will appear in the tool palette.

Undeclared identifier: 'TCustomChart'

I'm not sure how the compiler can be finding TCustomChart to build TIWChart and not finding TCustomChart later to use TIWChart.
