I'm using the example code here, but getting errors in this area.

for (i = 0; i < CPENS; i++) {

phbmp[i] = CreateCompatibleBitmap(

hdcMain, wLineX, wLineY);

if (i == 0) {

hbmpOld = SelectObject(hdcLines, phbmp[i]);

}

else {

SelectObject(hdcLines, phbmp[i]);

}

ExtFloodFill(

hdcLines, 0, 0, crMenuClr, FLOODFILLBORDER);

}

Code:

phbmp[i] = CreateCompatibleBitmap(hdcMain, wLineX, wLineY);

Error:

no operator "=" matches these operands operand types are HBITMAP__=HBITMAP

Code:

hbmpOld = SelectObject(hdcLines, phbmp[i]);

Error:

a value of type "HGDIOBJ" cannot be assigned to an entity of type "HBITMAP" no suitable conversion function from "HBITMAP__" to "HGDIOBJ" exists

    Probably some characters were lost. To fix the first error, try to add “[ ]” to these parameters: HPEN phpen[], HBITMAP phbmp[].

    To fix the conversion problems, try to use HGDIOBJ instead of HBRUSH and HBITMAP for corresponding local variables, for example: HGDIOBJ hbmpOld.

    Maybe you can use the Feedback button to report the found documentation errors.
