Yellow Progress Bar?

[Melchior]

Hi,

I am not a developer but a client for a development so excuse me for not using correct 'tech-speak'.

On our application we requested that a yellow progress bar is shown but our developers tell me that it is only available in blue. Is that correct or is there a way to specify the colour of the bar.

Here is what they wrote to me:

"It is possible to change the default color of the progress bar on desktop but not on Pocket PC. The default color of the progress bar on Pocket PC is blue. "

Thanks for any advice.

Melchior

PocketPC 2002 does not appear to support PBM_SETBARCOLOR
message. Any ideas on how to change the progress bar
color? Maybe subclassing it and hooking what message?
Thanks,

I can see no way to customize the color of the progress bar. But progress
bar is a pretty simple control and you can always reimplement it from
scratch.

Based on this I ASSUME that the only way to get what you want would be to implement your own progress bar control which as stated should not be any big deal to implement.

I wrote a progress bar class that displays the progress as a solid bar with
a percentage XOR'd with the bar color as the progress increases. (I didn't
like the CProgressBar provided by MFC) Following is the code that draws the
actual drawing. I can give you (or anyone else in this newsgroup) a copy of
the entire class if you would like to EMail me at jeffa@promodel.com

void CProgressBar::DrawBar(CDC &cdcBar)
{
CBrush cbrBrush,
cbrBar;
CRect rctColor,
rctClient;
WORD wCx,
wRange;
CFont cfFont;
CDC cdcBase,
cdcMem;
CBitmap cbmpBase, // BMP for memory DC
cbmpText; // BMP for memory DC

ASSERT_VALID(this);

// Get dimensions of progress bar
GetClientRect(&rctClient);

// Create a bitmap compatible with the screen.
// This will be used to blit the completed progress bar and thus prevent any
flicker.
cdcBase.CreateCompatibleDC(&cdcBar);
cdcBase.SaveDC();

// Create a bitmap compatible with the screen
cbmpBase.CreateCompatibleBitmap(&cdcBar, rctClient.right,
rctClient.bottom);
cdcBase.SelectObject(cbmpBase);

// Create a white canvass to draw on
cdcBase.SelectObject(GetStockObject(WHITE_BRUSH));
cdcBase.SelectObject(GetStockObject(WHITE_PEN));
cdcBase.Rectangle(rctClient);

// Calculate how far to display color
wRange = m_wEnd - m_wStart;
rctColor = rctClient;
wCx = (WORD)(((float)(m_wPosition) * rctClient.right)/wRange + 0.5);

// Now draw the color portion
rctColor.right = rctColor.left + wCx;
cbrBar.CreateSolidBrush(m_rgbColor);
cdcBase.FillRect(&rctColor, &cbrBar);

// Display the percentage complete
CString cszPct;

cszPct.Format(_T("%d %%"), (m_wPosition*100)/wRange);

// Draw text to a bitmap in memory
cdcMem.CreateCompatibleDC(&cdcBase);
cdcMem.SaveDC();

// Create a bitmap compatible with the screen
cbmpText.CreateCompatibleBitmap(&cdcBase, rctClient.right,
rctClient.bottom);
cdcMem.SelectObject(cbmpText);

// Make our memory bitmap all white
cdcMem.SelectObject(GetStockObject(WHITE_BRUSH));
cdcMem.SelectObject(GetStockObject(WHITE_PEN));
cdcMem.Rectangle(rctClient);

// Select a 10-point Times New Roman font
cfFont.CreatePointFont(100, _T("Times New Roman"), &cdcBase);
cdcMem.SelectObject(&cfFont);

// Give our text a transparent background
cdcMem.SetBkMode(TRANSPARENT);
cdcMem.SetTextColor(m_rgbColor);

// Finally, draw our text
cdcMem.DrawText(
cszPct,
cszPct.GetLength(),
rctClient,
DT_CENTER | DT_SINGLELINE | DT_VCENTER);

// Now blit the text bitmap to the bar
// NOTE: We want colored text to change to white as the progress
// bar moves underneath it. The ternary raster code for
// this is DSxn, index 99 in the ternary raster code table.
cdcBase.BitBlt(
0, 0,
rctClient.right, rctClient.bottom,
&cdcMem,
0, 0,
0x00990066 // DSxn raster code
);

// Blit the completed progress bar to the destination DC
cdcBar.BitBlt(
0, 0,
rctClient.right, rctClient.bottom,
&cdcBase,
0, 0,
SRCCOPY // Blit source to dest. DC
);

// Restore our original device context
cdcMem.RestoreDC(-1);
cdcBase.RestoreDC(-1);
}

This might be a good start.
Better would be to contact Jeff Armstrong, jeffa@promodel.com, and ask him to send you the complete code.

Wow, what a great response! Thanks Bob :D
