Images in Editor gadgets!

yep, that seems to be a way to determine the drop.

Was just entering the world of EN_DRAGDROPDONE. This saved me some time.


Thanks again.

Here is a modification of the code to drag and drop a text file or image file to the editor:

Very nice code Nico - works brilliantly here.

[cas]

Is it possible to use CatchRTF() with #SF_RTF to append new rtf formatted text to existing rtf text in EditorGadget?
I tried with replaceall=0 but it still replaces all data in EditorGadget with new data.

Thanks

[srod]

You need to set replaceall = #SFF_SELECTION.

E.g.

Code: Select all

Thanks srod. replaceall=#SFF_SELECTION solved my problem.

[cas]

I have a question about CatchRTF() LoadRTF() and SaveRTF() .
In comments before procedures it says:

;Returns zero if no error encountered.

But here always returns -2147024858.
I changed

Code: Select all

ProcedureReturn edstr\dwError

to

Code: Select all

ProcedureReturn edstr\dwError<<31

to get return 0. But after adding GetLastError_() between SendMessage_() and ProcedureReturn i get error code 6 which means "The handle is invalid".

So does it mean that there always some error happen even if it successfully displays content in EditorGadget? Or did i miss something (probably ).

Thanks

[srod]

I get no error codes here.

The value in edstr\dwError can be set by Windows (if it encounters a problem whist streaming) or it is simply the return value from the streaming callback function (which again will be placed there by Windows). For the majority of cases this should be zero.

Now, the code in this thread has been chopped and changed by a few people over the years so I would first have a good look at the edit-stream callback functions to make sure there is nothing obviously amis with the code. After that, I would ask as to the source of the rft files which you are streaming? If they were created by MS Word, for example, then expect problems! The rich-edit control simply does not like MS Word created rtf files!

Beyond this.... I do not know. As I say, I can not reproduce the problem here.

[cas]

Thanks for replying. I get these error returned with any data streamed in, even with your example here which inserts data to end (3 posts up). It outputs smileys here but it's just that odd error message, everything else looks right. Maybe the problem is with ansicpg1252 or deflang2057 so it can't find it on my system and it automatically changes to default one for my system and that error message is just a warning that original rtf data is not displayed but changed one. I tested it on Windows XP x86 and Windows 7 x64 with PB 4.40, 4.41 and 4.50 x86 and i always get same result.

[srod]

That sounds plausible yes (the code page).

For anyone that's interested, here's how to set the start indent & spacing for the bullets:

Change this:

Code: Select all

Procedure Editor_Bulleted(Gadget) 
  format.PARAFORMAT 
  format\cbSize = SizeOf(PARAFORMAT) 
  format\dwMask = #PFM_NUMBERING
  format\wNumbering = #PFN_BULLET
  SendMessage_(GadgetID(Gadget), #EM_SETPARAFORMAT, 0, @format) 
EndProcedure 

to this:

Code: Select all

Procedure Editor_Bulleted(Gadget) 
  format.PARAFORMAT 
  format\cbSize = SizeOf(PARAFORMAT) 
  format\dwMask = #PFM_NUMBERING|#PFM_OFFSET|#PFM_STARTINDENT
  format\wNumbering = #PFN_BULLET
  format\dxStartIndent = 200; Space between left margin & bullet
  format\dxOffset = 300; Space between bullet & start of text
  SendMessage_(GadgetID(Gadget), #EM_SETPARAFORMAT, 0, @format) 
EndProcedure
