Hi Guys,

 

I have a multiline edit box (non-MFC) in pure c++ and can display text happily in it.

 

But how do I make the edit box scroll automatically to the bottom of the text (once the edit box has filled up). At the moment I have to scroll manually.

 

This is my edit boxcreation code

 

hEdit=CreateWindowEx(WS_EX_CLIENTEDGE,"EDIT","",WS_CHILD|WS_VISIBLE|ES_MULTILINE|ES_AUTOVSCROLL|WS_VSCROLL,0,0,nNewWidth-16,nNewHeight-36,hWnd,(HMENU)IDC_MAIN_EDIT,GetModuleHandle(NULL),NULL);
 
strcpy(buffer,"Some text \r\n");
SendMessage(hEdit,WM_SETTEXT,NULL,(LPARAM)buffer);

 

Any advice would be awesome :)

This should do what you want

EDIT: But since it isn't on a dialog you don't need to call GetDlgItem, just use the edit hWnd directly.

Thanks for your reply. Just tried this. But, this seems to only select the text and doesn't actually scroll to the bottom of the editbox unfortunately.

Although you did put me on the right track :)

 

SendMessage( hEdit, EM_LINESCROLL , 0, 65535 );
