HMG 3.1.4

[Carlos Britos]

Hi.
the below attachments, capture and exe are on Xp.
The exe is not an HMG code but the related function SetCuebanner() is Almost identical. The exe is just to show the behaviour. The exe wwas compiled with harboour 3.2 and bcc but is the same with MinGW. Unicode and Ansi.

Hi Carlos, thank you for your patience and contribution. But your exe here in WinXP SP2 lamentably not working...

Shall be SP2/SP3 the problem ?

In Win7 is working perfectly.

Maybe I have sp3

And for Spinner and ComboBox did not worked in HMG (even in Win7) and also not for EDITBOX, RICHEDITBOX (these last two, you said already not working).

CueBanner is supported in XP as declared in MSDN here.

http://msdn.microsoft.com/en-us/library ... 85%29.aspx

And as the MSDN suggests,

"Note To use this API, you must provide a manifest specifying Comclt32.dll version 6.0. For more information on manifests, see Enabling Visual Styles."

We have a manifest file in HMG Resource path. But how to enable!?

Yes Rathi, I also have found this... but I still do not understanding. I guess something in C:\hmg.3.1.4\MINGW\include\commctrl.h where COMCTL32_VERSION is declare to 5 or 6... but this is in MINIGW.

Remember combobox and spinner are specials controls, two or more in one.
The combobox has listbox + textbox or label and spinner has updown + textbox.
To set the cuebanner you need the handle of the edit part. The textbox of combobox or spinner.

Ahhh yes, you are right. I do not know how to do it, I will continue searching...

May you try to correct this code for us ?

Probably for EditBox and RichEditBox would exist a way for do it too...

[Carlos Britos]

Please try with code
Note that:
in spinner GetControlHandle() return an array. So SetTextBoxCueBanner() need a trick to work.
in combobox I'm using FindWindowEx( GetControlHandle( "Combo_1", "Form_1" ), 0, "Edit", Nil ) to get the handle of textbox.

Probably, I'd tried time ago but with no luck, sorry.

Hi Pablo

En MSDN I saw this comment:

wParam option note

wParam TRUE - only appears to work on Vista.

Under XP the cue text always disappears when the control gets focus regardless of this parameter.

Can you try if this is true for us ?
Maybe is the problem with sp2

The combobox has listbox + textbox or label and spinner has updown + textbox.
To set the cuebanner you need the handle of the edit part. The textbox of combobox or spinner.

Hi boys,
this is how to get all handles of a control:

Code: Select all

hControl := GetControlHandle (cControlName, cParentName)

IF Valtype (hControl) == "A"
    FOR i = 1 TO LEN(hControl)
        ControlHandle := hControl [i]
        ProcessControlHandle (ControlHandle)
    NEXT
ELSE
    ControlHandle := hControl
    ProcessControlHandle (ControlHandle)
ENDIF


Procedure ProcessControlHandle (ControlHandle)
   // code for process ControlHandle
Return
