Thread: Adding text where cursor is?

I am working on a simple HTML editor with a styles wizard. I know how to generate the text but I can only figure out how to add the text to the end. I want to insert it wherever the cursor is but dont know how. This is what I have so far:

Code:

case IDOK:{
int len = GetWindowTextLength(GetDlgItem(hWnd, IN_HOVERCOLOR));
char* ret_color;
ret_color = (char*)GlobalAlloc(GPTR, len + 1);

GetDlgItemText(hWnd, IN_HOVERCOLOR, ret_color, 16);
//ret_color now has value of IN_HOVERCOLOR//

HWND hwndpar;
hwndpar = GetWindow(hWnd,GW_OWNER);
HWND hEdit;
hEdit = GetDlgItem(hwndpar, MAIN_EDIT);

char* before_text;
int txtlen = GetWindowTextLength(hEdit);
before_text = (char*)GlobalAlloc(GPTR, txtlen + 75);
GetWindowText(hEdit, before_text, txtlen+1);
char style_text[75];
strcpy(style_text,"<style>\r\n<!--\r\na:hover{color:");
strcat(style_text,ret_color);
strcat(style_text,";}\r\n-->\r\n</style>"); //22 len
//Style Text now has the style tag//
strcat(before_text, style_text);
SetWindowText(hEdit, before_text);
//Free up memory//
GlobalFree(before_text);
EndDialog(hWnd, wCommand);

}
break;

Most times the cursor will be at the end of the text. Could look at the WM_COMMAND messages for the edit.

use
case ID_EDIT:
if (EN_CHANGE == HIWORD(wParam)) //user is typing text so cursor is at end

or play with SendMessage() and EM_GETSEL (could work?)

I think you are going to have some size errors here if length ret_color is about 30 or more. Alloc some more mem here

Code:

strcpy(style_text,"<style>\r\n<!--\r\na:hover{color:");
strcat(style_text,ret_color);
strcat(style_text,";}\r\n-->\r\n</style>"); //22 len

better would be

Code:

char *before_text, *edit_Text;
int     iLen=0;

iLen=  lstrlen( "<style>\r\n<!--\r\na:hover{color:" ) 
       + lstrlen( ";}\r\n-->\r\n</style>" ) 
       + lstrlen(ret_color) 
       + GetWindowTextLength( hEdit );
//you should always error test the mem allocs
edit_Text     = (char*)GlobalAlloc(GPTR, GetWindowTextLength ( hEdit ) + 1);
before_text = (char*)GlobalAlloc(GPTR, ilen + 1);

//use one sprintf with a %s type where the other string are added

sprintf(before_text,"%s<style>\r\n<!--\r\na:hover{color:%s;}\r\n-->\r\n</style>" , before_text, ret_color);
SetWindowText(hEdit, before_text);

//free mem

Since this is an HTML editor i decided to make a function to add text to a edit box in any window.

Code:

BOOL InsertText(HWND hnd, INT id, LPSTR txttoins2){
BOOL bSuccess = FALSE;
HWND newHandle = GetDlgItem(hnd, id);
int LenOLD = GetWindowTextLength(newHandle);


char* txttoins, *OLDTEXT;
txttoins = (char*)GlobalAlloc(GPTR, strlen(txttoins2)+1);
strcpy(txttoins, txttoins2);
OLDTEXT = (char*)GlobalAlloc(GPTR, LenOLD+strlen(txttoins2)+1);
GetWindowText(newHandle, OLDTEXT, LenOLD+1);
strcat(OLDTEXT, txttoins);
if (SetWindowText(newHandle, OLDTEXT)){
bSuccess=TRUE;
}


GlobalFree(OLDTEXT);
GlobalFree(txttoins);
return bSuccess;


}

My old code was very sloppy but I am a newbie. Is this one any better? Another question is how do I set up a menu to copy,paste,select text in hEdit (handle: hwnd). Do I have to use clipboard functions or is there an easier way to do it?
