create richtext at runtime, in web app

[aberbotimue]

X-posted - Its stumped me, and another forumds thus far!

Can anyone point me in the right direction..

I am running a very quick cgi web application.. but require a print out as an rtf..

in a stand alone app I drop the richtext componant on, and it does what it needs, and then prints, like i want it to.

in the web app, I have to create it at run time.. so I have

with TRichedit.Create(self) do
try
  Visible := false;
  lines.loadfromfile('c:\formations\testfile.rtf');
  // Print('Printer');
finally
   Free;
end;

this gives me an error like

Internal Application Error
 
Control '' has no parent window

after some time with my good freind google, I found loads saying its about allocating an appropriate parent

so I added

  parent := self;
 
and tried
 
  parent := nil;
 
even tried   

  parent := application.webform;

all giving me compile errors.. as you may have guessed, i am a weekend coder, not doing this day in day out...

can anyopne give me that special line I need!

Cheers all

with TRichedit.Create(nil) do

Thanks Roo

but still gives the

Control 'RichEdit2' has no parent window

error

so I now have

Fbox := TRichedit.Create(nil) ;
with Fbox do
begin
    Name := 'RichEdit2';
    Parent := nil;
    Left := 208;
    Top := 224;
    Width := 185;
    Height := 89;
    Lines.Clear;
    Lines.Add('RichEdit2');
    TabOrder := 0;
end;

Parent := nil;

Remove the above.
(You can't assign a value to something that doesn't exist.)

If only!!

Thats where I started...

removing the parent gives

Internal Application Error
Control 'RichEdit2' has no parent window 
c

When you apply parent to the 'TWebModule1' via self, you get

[code]
[DCC Error] codebase.pas(299): E2010 Incompatible types: 'TWinControl' and 'TWebModule1'
[code]

The angle i was pondering was casting the 'TWebModule1' to 'TWinControl'  But wouln't know where to start, or even if one could.

I have achived other visual componants with ease, it just seems to be the RTF componant that required a parent?

Delphi's Richedit control is based on microsoft's Richedit control. This control needs a parent window handle to be able to process window messages sent to the control.

I don't know if you can create normal TForms in a web application. IF you can do this then create a Form at runtime with the Richedit on it.

daddy's right - I'd forgotten about it being parent dependant. Sorry if I misled you.

Daddy, Thanks, I'll have a go at that.. Not as easy, as I am not sure how to create a form, either on the fly!!

Roo.. god no, thanks for the help.. I thought I was just going mad, as I could create other stuff, and not this!! I am genuenly thankfull for your time, for taking the effort to reply..

I'll drop some code back here when I have givven it a try!! and let you know what happened...
