SETRGBSTRING
The hook procedure of a Color dialog box can send the SETRGBSTRING registered
message to the dialog box to set the current color selection.
MessageID = RegisterWindowMessage(SETRGBSTRING);
wParam = 0;
lParam = (COLORREF) rgbColor;
Parameters
rgbColor
Specifies the RGB value of the color to select in the Color dialog box. You
can use the RGB macro to specify the red, green, and blue intensities of an RGB color value.
Return Values
No return value.
Remarks
If rgbColor matches one of the basic colors or one of the 16 custom colors, the dialog
box procedure selects that color. The dialog box procedure also updates all the
controls in the custom color extension of the Color dialog box, if it is open.
If rgbColor does not match a basic or custom color, the dialog box procedure does not
change the current color selection, but it does update the custom color controls,
if they are visible.
For example, the following sample code gets the SETRGBSTRING message
identifier and then sets the color selection to blue.
UINT uiSetRGB;
uiSetRGB = RegisterWindowMessage(SETRGBSTRING);
SendMessage(hwndDlg, uiSetRGB, 0, (LPARAM) RGB(0, 0, 255));
