Hints:
Please note the general hints in the section "1.3.3. Variables and Fields".
This function defines a text field and can be mixed with the other
LlDefineField...() functions.
List & Label predefines the fields listed in LlDefineField().
The metafile handle must be valid as long as it is needed, that is during the
entire layout definition or until after LlPrintFields() or LlPrint() has finished.
After use the handle can or should be deleted with the normal API function.
Example:
hJob hJob;
HMETAFILE hMeta;
HDC
hMetaDC;
INT
i;
hMetaDC = CreateMetaFile(NULL); // Fieberkurve
selectObject(hMetaDC,GetStockObject(NULL_PEN));
Rectangle(hMetaDC, 0, 0, LL_META_MAXX, LL_METY_MAXY);
for (i = 0; i < 10; ++i)
{
MoveTo(hMetaDC,0,MulDiv(i, LL_META_MAXY, 10));
LineTo(hMetaDC,MulDiv(i, LL_META_MAXX, 100),
MulDiv(i, LL_META_MAXY, 10);
}
MoveTo(hMetaDC, 0, MulDiv(((100*i) & 251) % 100, LL_META_MAXY,100));
for (i = 0; i < 10; ++i)
LineTo(hMetaDC,MulDiv(i, LL_META_MAXX, 10),
MulDiv(((100*i) & 251) % 100, LL_META_MAXY, 100));
hMeta = CloseMetaFile(hMetaDC);
hJob = LlJobOpen(0);
LlDefineFieldStart(hJob);
LlDefineField(hJob, "Name", "Normalverbraucher");
LlDefineField(hJob, "Vorname", "Otto");
LlDefineFieldExt(hJob, "Ort", "Konstanz", LL_TEXT, NULL);
LlDefineFieldExtHandle(hJob, "Erfolgs-Chart", hMeta,
LL_DRAWING_HMETA, NULL);
<... etc ...>
LlJobClose(hJob);
DeleteObject(hMeta);
