  IW 16.1.9 Invalid property value loading forms with frames
Posted by: Fabrizio Conti - 01-15-2026, 02:12 PM - Forum: IntraWeb General Discussion - No Replies

Hi,
after installing IW 16.1.9 in Delphi 13 I have errors opening old forms.
The errors are “error reading IWGradButton1.Style.Button.ToColor: invalid property value” or similar error for  IWLabel1.Font.ToColor property.
This happens only when the controls are placed in a child frame that is placed in a parent form through the IDE.
Opening the child frame itself does not cause the error.

I tried the Frame Inheritence Demo and there is the same error opening the uChildFrame1 form.
The same happens in IW 16.1.8.

  TIDFTP sending short files goes to timeout
Posted by: Dany40 - 01-14-2026, 05:40 PM - Forum: Indy - Replies (18)

Hi;

I use a TIDFTP client in a RadStudio 10.4 project that connects to a FileZilla Server for sending thoudands of little files (1kb to 4 or 5 MB). The client is set to send in pasive mode and bynari mode, using PUT:

Code:
Ftp.Put(sSoruceFile, sTargetFile, False, -1);

In the very big number of files it sends every week, 3 or 4 different and small files (2 kb in size) appeared that could not be transferred to that server; FileZilla is receiving them, sure in only one package as those files are very little in size; but after the client reaches the 60 seconds timeout, the Put raises a read error. When I see at the server side, the file only have 1300 bytes, when the original file is 2406 bytes.

Using one of the files that fails, I can reproduce the same 100% of the times I try. I attached here a test file.

FileZilla server is 1.12.1 version, and it is running on a Windows 11 PRO virtual machine and behind a NAT.

Thank you in advanced for any idea or clue I can follow!

  Delphi 13.0 : CGDevTools Registration
Posted by: s.noel - 01-05-2026, 02:38 PM - Forum: CGDevTools - Replies (3)

Hello,
I’ve downloaded the latest version of CGDevTools 5.0.0 RC4 and successfully installed IntraWeb 16.1.8, entering the corresponding license key during installation.
However, when I open my IDE 13.0 Florence, I don’t see the CGDevTools tab that should allow me to register the CGDevTools license.
Did I miss any step or additional configuration?
Thank you in advance for your help.
Best regards.

  Win64 - Add/delete SSL Certificate binding prompt error "Parameter is incorrect"
Posted by: lmengyew - 01-02-2026, 07:58 AM - Forum: IntraWeb General Discussion - No Replies

Hi,

I am using IWHSysHeaders provided by the IntraWeb library to programmatically add and delete SSL certificate binding at runtime. 

The code works correctly on the Win32 platform; however, on Win64 it returns the error “The parameter is incorrect” when calling 

Code:
HttpSetServiceConfiguration

and

Code:
HttpDeleteServiceConfiguration

I have attached a sample project for your reference. To reproduce the issue, please update the Host, CertStoreName and CertThumbprint values before running the program. 

Could you please advise what might be wrong with my implementation and how this issue can be resolved?

Question RenderInvisibleControls property does not exist
Posted by: mrmister - 12-15-2025, 12:49 AM - Forum: IntraWeb General Discussion - No Replies

I have IW 16.1.8 installed into Delphi 13 (Enterprise) on 2 machines. On one machine, I can open an IW form, no errors. On the 2nd machine, when opening an IW form, I get "renderinvisiblecontrols does not exist". Searching for BPLs gives the same list of files/dates/size named *intraweb*.bpl on both machines.

What am I missing?

  can't compile
Posted by: tobenschain - 12-12-2025, 10:44 AM - Forum: IntraWeb General Discussion - Replies (2)

I am getting the following error:

[dcc32 Fatal Error] madIWSupport.pas(29): F2051 Unit IWAppForm was compiled with a different version of Vcl.Controls.TWinControl.CanUseDoubleBuffering

I use MadExcept and IntraWeb. I have installed and reinstalled. IWAppForm.pas is only in c:\users\toben\AppData\Roaming\IntraWeb 16\LibLazarus\source\public.

So I can't generate a new  IWAppForm.dcu

  Indy for Lazarus and SSL v3.x
Posted by: dpapdpap - 12-07-2025, 06:53 AM - Forum: Indy - Replies (5)

Hi, I use lazarus 4.4/64bit for windows11. My app needs to make HTTPs calls but i faced this problem. If I use the SSL binaries v3.x idHTTP can't recognize them. I adviced to use v1.1 but I can't find them. At the https://github.com/IndySockets/OpenSSL-Binaries are only v1.0 and v3.x.  
My question is: is There a working link from where I could download precompiled binaries that work with indy10 at Lazarus64/win or is there another way to make indy able to make SSL calls?
Thanls in advance
