Web Server - Ask For Help / How to execute code once on Form Load?
« Last post by JohanR on September 24, 2026, 02:43:47 AM »Hi,
What is the preferred method or embed to ensure code only runs once on form generation, popup or page loaded.
I am currently using
if (p_web.GetValue('SignInResetPassword_form:inited_') = 1)
Using code below, it runs through twice, even if checking on p_web.SetValue('SignInResetPassword_form:inited_',1)
Attached code and debuglog for initform and preupdate code/logs
thanks for any advice
Johan
InitForm Routine
DATA
LF &FILE
! Start of "Initalize the Form before anything else is done"
! [Priority 5000]
! End of "Initalize the Form before anything else is done"
CODE
! Start of "Initalize the Form before anything else is done"
! [Priority 5000]
ds_OutputDebugString('>>> InitForm <<<' & format(clock(),@t06))
if (p_web.GetValue('SignInResetPassword_form:inited_') = 1)
ds_OutputDebugString('========== 2nd time' & format(clock(),@t06))
else
ds_OutputDebugString('========== 1st time' & format(clock(),@t06))
end
! End of "Initalize the Form before anything else is done"
p_web.SetValue('SignInResetPassword_form:inited_',1)
p_web.formsettings.file = ''
p_web.formsettings.key = ''
do RestoreMem
! Start of "Initalize the Form before anything else is done"

Also there are services that (like this webhooker) take care of the pesky details

« Last post by Bruce on September 21, 2026, 01:12:49 PM »I think you'll find the current error fits inside the minimum TCP packet size. You won't see any performance difference making it smaller.
But of course you can derive your own code into the SendError (or wherever) to send back whatever you like.

That is pretty nifty. Good example of JS use. Very helpful for those of us who are slowly getting our toes wet with JS.
Thanks for sharing.

It sets the button to transparent with no border and no outline.

« Last post by Richard I on September 17, 2026, 06:07:17 PM »Hi Jane,
I have it working, thank you, in my app.
But I do have one issue please.
My TogglePasswordButton, while having the eye icons ok, is coloured solid blue and is the same size and border defined as the other fields,
whereas your button in your app, is hidden with only the icon showing.
I have added to my app, your custom.css
Ill check the CSS files and add Color Transparent, but
If you could comment, on the size ,that would be appreciated.
Regards,
Richard

Web Server - Ask For Help / Custom response headers
« Last post by the_question on September 17, 2026, 07:27:04 AM »Hello,
I am trying to add some elements in response headers for NetWebPage. I have found in NetWebHandleRequest p_web.CreateHeader procedure. There is a parameter NetWebServerHeaderDetailsType p_HeaderDetails. When I add data in p_HeaderDetails.CustomHeader before ReturnValue = PARENT.CreateHeader(p_HeaderDetails) call, nothing is saved in generated header.
How can I add elements in response header?

Think you need to save the PDF to disk and then specify the name of the file in the media control.
