DWORD GetTextExtent(hDC,lpString,nCount)
This function computes the width and height of the line of text pointed to by the lpString parameter. The GetTextExtent function uses the currently selected font to compute the dimensions of the string. The width and height (in logical units) are computed without considering the current clipping region.
| Parameter | Type/Description |
| hDC | HDC Identifies the device context. | |
| lpString | LPSTR Points to a text string. | |
| nCount | int Specifies the number of characters in the text string. |
The return value specifies the dimensions of the string. The height is in the high-order word; the width is in the low-order word.
Since some devices do not place characters in regular cell arrays (that is, they carry out kerning), the sum of the extents of the characters in a string may not be equal to the extent of the string.
