Support for PB-like templates:

In modToolbar.inc change

Code: [Select]
   Toolbar_AddButton hToolBar, i, IDM_FILENEW, 0, TBSTYLE_DROPDOWN

to add a dropdown arrow to the New File item.

In frmMain_OnNotify add the following code to process the dropdown notification:

Code: [Select]
   SELECT CASE pNMHDR->idFrom
      CASE IDC_FRMMAIN_TOOLBAR
         DIM ptbn AS TBNOTIFY PTR = CAST(TBNOTIFY PTR, pNMHDR)
         IF ptbn->hdr.code = TBN_DROPDOWN THEN
            SELECT CASE ptbn->iItem
               ' // Dropdown new file menu
               CASE IDM_FILENEW
                  DIM rc AS RECT
                  SendMessageW(ptbn->hdr.hwndFrom, TB_GETRECT, cast(WPARAM, IDC_FRMMAIN_TOOLBAR), CAST(LPARAM, @rc))
                  MapWindowPoints(ptbn->hdr.hwndFrom, HWND_DESKTOP, CAST(POINT PTR, @rc), 2)
                  frmTemplates_Show(hwnd, rc.Left, rc.Bottom)
            END SELECT
         END IF
   END SELECT

Module for templates loading:

Code: [Select]
CONST IDC_TEMPLATES_LISTBOX = 101

This is the TODO part:

Code: [Select]
                     ' // Open the template
                     IF pwszPath THEN
                        ' // TODO: Create a new Scintilla control
                        ' // TODO: Load the file
                        ' // TODO: Search for "|", replace it with "" and position the caret in that place
                        ' // Replace the marker with an empty space
                        ' SCIP_FindReplace(pSci, "|", "")
                        ' // Set the state of the document as unmodified
                        ' SCIP_SetSavePoint(pSci)
                        ' // The SCIP_xxx functions are located in the SciCtrl.inc file of the PowerBASIC headers
                     END IF

Note: Load the template as Untitled<number>.bas.

Thanks Jose :)   I have most of the code implemented now. Only had to do some changes in order to make it fit within the style I'm using (message crackers, etc). I also had to make the following small change. You used the toolbar identifier instead of the toolbar button identifier.

Instead of:
   SendMessageW(ptbn->hdr.hwndFrom, TB_GETRECT, Cast(WPARAM, IDC_FRMMAIN_TOOLBAR), Cast(LPARAM, @rc))
Use:
    SendMessageW(ptbn->hdr.hwndFrom, TB_GETRECT, IDM_FILENEW, Cast(LPARAM, @rc))

I also removed the WS_THICKFRAME style from the Templates window.

I coded it as a separate test without a toolbar and part of the code was theoretical. My major concern was to build the array of paths. With REDIM PRESERVE apparently the memory changed and some of the pointers stored in the listbox where no longer valid. This is why I first get the number of files to dimension the array.

Sounds good. I was wondering why you did that with the array. Better safe than sorry if REDIM PRESERVE is causing a problem.
The only other difference I coded was to NOT set the save point after loading the template file. This keeps the file buffer dirty (and displays the "*" indicator) so that the user can either save the file as the default "UNTITLED1.BAS", "UNTITLED2.BAS", "UNTITLED3.BAS", etc.. or Save As a different name.

The templating system you have made is pretty cool.

This is because my editor allows to compile and run code that does not use resources without saving it first. The editor saves it to a temporary file before compiling it. If I don't set the save point, the editor will ask me to save the file. It is very useful when doing small tests.

The number 2 indicates the number of lines before the description:

FBGUI
.bas

FBGUI means that it is a gui program, and FBCON that it is a console program. I use it to know if I have to call the compiler with the gui or console switch.

The .bas line is to indicate the type of program: .bas for basic code, .xml for manifests, etc.
