DCSLIDE.PRG(25:0): warning XBT0102: Ambiguous variable reference aGETLIST_VARS

You have an older version of eXpress++ (DCDIALOG.CH).

Also, I am sending you build 263 by email.

For now, just remove the following from DCSLIDE.CH:

Code: Select all

       ;DC_GetListSet(DCGUI_GETLIST,aGETLIST_VARS,                          ;
                     {'DCSLIDE',<(ooo)>,<(oParent)>,nil,                    ;
                       #<nRow>,#<nCol>,#<nWidth>,#<nHeight>} )

This is there only for the designer system of build 263 or later. It's not needed.

Ok with lates Express++ Version all work fine

Question : if i add more Method how to add it into DCSLIDE.CH ?

Code: Select all

oVert1:SetiThumb(1,"ICO")                       -> Load Thumb Icon from Resource Type "ICO"
oVert3:SetiMarker(3,"ICO")                      -> Load Marker Icon from Resource Type "ICO"
oVert3:SetiBackground("WHITE_CYAN.BMP" ,"BMP")  -> Load Background Image from HDD/SDD Type "BMP"

Syntax : SetiXXX(<Resource ID>|<cFilename>, <"ICO">|<"BMP">)
Return : Number in Imagelist ( zero-based )

while Resource can be in DLL i have a iVar cDllName

Code: Select all

   ::cDllName := AppName(.t.)

so default is EXE.

Question : how to call it in Express++ ?

i saw in DCSLIDE.CH

Code: Select all

   [RESTYPE <cResType>]   ;
   [RESFILE <cResFile>]   ;

is this to point to Resource File ?

Question : if i add more Method how to add it into DCSLIDE.CH ?

DCSLIDE.CH is used to parse command line parameters into the GetList array.

This is a multi-dimensional array that has 70 elements per GUI item.

DCSLIDE is not using the xGETLIST_OPTIONS3 thru xGETLIST_OPTIONS9 elements.
I see that I didn't finish the job.

I recommend adding the following after line 97:

Code: Select all

    [;DC_GetListSet(DCGUI_GETLIST,xGETLIST_OPTIONS3,{<cResType>,<cResFile>})] ;

Then you would add some code to DCSLIDE.PRG:

In the function DC_DxeSlide():

Code: Select all

aOptions3 := aGetListItem[xGETLIST_OPTIONS3]

IF Valtype(aOptions3) == 'A'
  SetOption( @oSlide:resfile, aOptions3[2] )
  SetOption( @oSlide:resType, aOptions3[1] )
ENDIF

You would need to modify it to your exact needs but that is the basic idea.

hi,

1.) add in DCSLIDE.CH

Code: Select all

   [ICOTHUMB  <iThumb>]                                        ;
   [ICOMARKER <iMarker>]                                       ;
   [ICOIMAGE  <iImage>]                                        ;

2.) add <iThumb>,<iMarker>,<iImage> as 11,12,13

Code: Select all

    ;DC_GetListSet(DCGUI_GETLIST,xGETLIST_OPTIONS,                       ;
      {<orient>,<r1>,<r2>,<freq>,<buds>,<budl>,<budr>,<thumb>,<style>,   ;
       <.tb.>,<iThumb>,<iMarker>,<iImage> } )                            ;

3.) add after line 97

Code: Select all

   [;DC_GetListSet(DCGUI_GETLIST,xGETLIST_OPTIONS3,{<cResType>,<cResFile>})] ; // NEW by Jimmy

4.) in DCSLIDE.PRG

Code: Select all

   PAINTSTYLE "VISUAL" ;                        // ADD by Jimmy
   RESFILE "DCSLIDE.DLL" ;                      // NEW by Jimmy
   RESTYPE "ICO" ;                              // NEW by Jimmy
   ICOTHUMB 1    ;                              // NEW by Jimmy
   ICOMARKER 3   ;                              // NEW by Jimmy
   ICOIMAGE 100  ;                              // NEW by Jimmy

5.) in DC_DxeSlide()

Code: Select all

LOCAL aOptions3 := aGetListItem[xGETLIST_OPTIONS3]   // NEW by Jimmy
...
   IF Valtype(aOptions3) == "A"                    // NEW by Jimmy
      SetOption( @oSlide:cDllName, aOptions3[2] )  // NEW by Jimmy
      // need more than 1 Image Type 
      SetOption( @oSlide:cImgType, aOptions3[1] )  // NEW by Jimmy
   ENDIF
   IF Valtype(aOptions[11]) $ 'CN'                  // iThumb
      oSlide:SetiThumb(aOptions[11],aOptions3[1])
   ENDIF
   IF Valtype(aOptions[12]) $ 'CN'                  // iMarker
      oSlide:SetiMarker(aOptions[12],aOptions3[1])
   ENDIF
   IF Valtype(aOptions[13]) $ 'CN'                 // iBackground
      // need more than 1 Image Type 
      oSlide:SetiBackground(aOptions[13],"BMP")
   ENDIF

now i got all ICO / BMP and work fine

DC_Slider.jpg (45.81 KiB) Viewed 11412 times

Question :

as i can use ICO and BMP (JPG/PNG etc) in Imagelist which are in same DLL how to fix this in Express++ (RESTYPE) ?

when using Resource from DLL it must be "load" before. DCRES.PRG have only

Code: Select all

   FUNCTION DUMMY
   RETURN NIL

but i have link RES File to it

Code: Select all

[DCSLIDE.DLL]
    COMPILE_FLAGS = /dll /n /q /w
// $START-AUTODEPEND
    DCSLIDE.RES
    DCRES.OBJ
    DCSLIDE.DEF
// $STOP-AUTODEPEND
    DCSLIDE.ARC
    DCRES.PRG

now in MAIN i have to call DUMMY() in 1st Line ... how do it better with Express++ ?

[Auge_Ohr]

hi,

can someone please show a Express++ Newbie how to RESIZE ( maximize ) work with DcSlider.PRG

Question : how to resize the Static which show the Color ?

Code: Select all

@ 100,0 DCSTATIC TYPE XBPSTATIC_TYPE_TEXT OBJECT oStatic ;
      SIZE 500,100 ;
      OPTIONS XBPSTATIC_TEXT_VCENTER+XBPSTATIC_TEXT_CENTER ;   // add by Jimmy
      RESIZE DCGUI_RESIZE_RESIZEONLY_X                         // add by Jimmy

but even this does nothing when maximize Window ...

p.s. in UseSlider.PRG resize work well.

The eXpress++ resizing system requires that each GUI class inherits from DC_XbaseParts.

I will have to look at your class again and see if I can create a a new sub-class from Dxe_Slider() and DC_XbaseParts().

I have been busy trying to get out a new eXpress++ build 264 this weekend but I will break from my work and see what I can do.

ok ... found

Code: Select all

CLASS DC_XbaseParts FROM DC_NoIvarContainer

I will have to look at your class again and see if I can create a a new sub-class from Dxe_Slider() and DC_XbaseParts().

if i have a Sample i can try to integrate it into other DXE Sample.

Question : how do it know if Express++ "IsAvaiableExpress" at Runtime ?

I have been busy trying to get out a new eXpress++ build 264 this weekend but I will break from my work and see what I can do.

so don´t hurry ... that we can do later.

[rdonnay]

Here are the changes I promised.

The resizing works perfectly.

BTW - You don't need the dummy call. This works just fine.

DllLoad('DCSLIDE.DLL')

This change requires that I needed to make a small change to my DCLIPX.DLL.

Copy _DCGETBX.PRG to your .\source\dclipx folder.
Run BUILD19_SL1.BAT or BUILD20.BAT to rebuild DCLIPX.DLL.
