Hi,
does anybody know how (and if it is possible) to retrieve the currently selected text in a multistring field? I am in a GeDialog btw.
I remember that there were messages sent when the user edits the field...maybe something like a message? I just don't remember where it was (way too long ago).
Thanks in advance

Thanks first of all. BFM_ACTION was what I meant! However, none of the actual action states give me the current text selection afai can see. :-/

hm, there are also these ids in bfm_message :

BFM_EDITFIELD_GETCURSORPOS

Returns the cursor position in an edit field ([LONG](file:///E:/Misc/SDK%20Help/C4d%20SDK%20Documentation%20C++/help/pages/ge_sys_math/typedef_ge_sys_math_584.html#LONG2)).
---|---
BFM_EDITFIELD_GETBLOCKSTART

Returns the block start position in an edit field ([LONG](file:///E:/Misc/SDK%20Help/C4d%20SDK%20Documentation%20C++/help/pages/ge_sys_math/typedef_ge_sys_math_584.html#LONG2)).
<_<_t_>_
sounds that the range between those could be the selected range, but i have never used them, so i might be wrong.

Yeah I had found these but they only seem to be for LONG edit fields (at least that was my assumption with the LONG statement), but I will try them. Thanks!

This is a snippet from my free AutoComplete plugin that finds the last word in a text box:
/////////////// This section gets the last word of text the user types into the texbox /////////////////
String allWords; //This will hold the entire text in the textbox
String lastWord; //This will hold the last word that is typed into a text box
if (msg.GetId()==BFM_GETCURSORINFO)
{
if(GetString(MY_MULTIBOX, allWords))
{
LONG length = allWords.GetLength();
LONG pos = NULL; //The variable that will hold the position of the string
Bool lastSpace = allWords.FindLast(" ",&pos, -1); //Find the last blank space and store it's position in the string

thanks Scott. Browsing strings is not the issue but I really need the selected text.

I understood LONG in that way, that those container ids are of type LONG, providing the caret
and block position as an integer value.

And I think you are absolutely right. Now that I also see SETCURSORPOS it seems pretty obvious. Thanks, I check if these work!

This is the solution I came up with for getting the selected text in a GeDialog() text box:
LONG myDialog::Message(const BaseContainer &msg, BaseContainer &result)
{
String text;
this->GetString (1001, text); //Get the text in the text box (1001 is the id for the edit text gizmo)
if(GetString(1001, text)) //If the edit text gizmo is not empty
{
//The cStart value is the position in the text where you started dragging(highligthing the text)
//The cPos value is the current position the cursor is in
//The range of selected text characters = cPos-cStart
BaseContainer blockStart(BFM_EDITFIELD_GETBLOCKSTART);
GeData bs = SendMessage(1001, blockStart);
LONG cStart = bs.GetLong();
BaseContainer cursorPos(BFM_EDITFIELD_GETCURSORPOS);
GeData cp = SendMessage(1001, cursorPos);
LONG cPos = cp.GetLong();
LONG numSelected = cPos-cStart; //The number of selected text characters
String selected = "";
if(numSelected >= 1) //If the user selected the text from left to right
{
GePrint("Start: " + LongToString(cStart) + " " + "Pos: " + LongToString(cPos) + " " + "NumSel: " + LongToString(numSelected));
for (LONG i=0; i<numSelected; i++)
{
String s = text.SubStr(cStart+i, 1);
String combine = selected.operator+=(s); //Adds the current char to the "selected" string variable
}
}
GePrint(selected);
}
return GeDialog::Message(msg,result);
}
Seems to work pretty well.
But I'm always interested in seeing how other people solve things. I learn new things that way.
So if you figured out another way to so it. I'd love to see what you came up with.

Hi Scott,
thanks for your example. Anyway, this only seems to work for a normal text field not a multistring field. In a multistring field the values are always 0.
So there is no way to retrieve this in a multistring (multiline) field (question pointed at support)?
