Transparent Text Background over progress bar
#1
Hi All,

It would be cool to have progress bar fill in over text. I know settings of "Static text transparent background" from http://www.quickmacros.com/forum/showthr...p?tid=3980. But there seems to be z-order issue. When update of progress bar occurs, it moves in front of text. Any tricks to keep the text on top of the progress bar?
Thanks, S

Thanks so much! Completely works as written. But how do I center text. It is starting from upper left. Only looks good if the width of text and size of progress bar are exactly same. Is it possible to center the text. If exceedingly complicated, not worth it...only if easy for you!,
Thanks so much as always, S

Instead of TextOut[W] use DrawText[Ex][W] with flag DT_CENTER. Reference in MSDN Library.

thanks!,

Looked here http://msdn.microsoft.com/en-us/library/...s.85).aspx

tried to do it like this based on above and dll user32 [DrawTextA]#DrawText hdc $lpchText cchText RECT*lprc format:

Code:
Copy      Help
,RECT r; DpiGetWindowRect dc &r ;;push button
,lpstr s = "TEST"
,DrawText dc s -1 &r  DT_CENTER

but text remains invisible.

not sure what you mean by [Ex] and [W] in DrawText[Ex][W]

Thanks, S

Quote:int DrawText(
_In_ HDC hDC,
_Inout_ LPCTSTR lpchText,
_In_ int nCount,
_Inout_ LPRECT lpRect,
_In_ UINT uFormat
);

Parameters
hDC [in]
A handle to the device context.
lpchText [in, out]
A pointer to the string that specifies the text to be drawn. If the nCount parameter is -1, the string must be null-terminated.
If uFormat includes DT_MODIFYSTRING, the function could add up to four additional characters to this string. The buffer containing the string should be large enough to accommodate these extra characters.
nCount [in]
The length, in characters, of the string. If nCount is -1, then the lpchText parameter is assumed to be a pointer to a null-terminated string and DrawText computes the character count automatically.
lpRect [in, out]
A pointer to a RECT structure that contains the rectangle (in logical coordinates) in which the text is to be formatted.
uFormat [in]
The method of formatting the text. This parameter can be one or more of the following values.
Value Meaning
DT_CENTER
Centers text horizontally in the rectangle.
