Justin:
My solution was fine except for the wrong second argument to the
ProgName_SYS function, the code should be:
real rWait, rT, rT0, rT1, rMinutes;
int iPercent;
......
rMinutes = 0.2; // insert your value here...
rWait = rMinutes/60.0; // convert to hours
rT0 = rTime_SYS();
rT1 = rT0 + rWait;
Progress_SYS(1);
ProgName_SYS("Pausing - Hit cancel to finish", 1);
do {
rT = rTime_SYS();
iPercent = (int)(100.0*(rT-rT0)/(rT1-rT0));
ProgUpdate_SYS(iPercent);
if(iCheckStop_SYS()) // Let user break out
break;
} while(rT1 > rT);
Progress_SYS(0);

Subject: [gxnet]: Pause GX
Dear list,
Our HP 2000CP plotter runs out of memory when I attempt to
print 100+ 10MB A4 plots to it. We are at the upper limit of the physical
memory & checking "process in computer" does not help. HP support have no
solutions, bar suggesting we buy a new plotter with a built in hard drive.
Not an option.
The solution is to modify the Mapprint gx to pause for a
user definable period of time, after processing a user definable number of
maps. In practise I have used the iFileSize_SYS(sMap) function to work out
how many maps can be printed at a time given the amount of plotter memory.
So I've completed the GX, but what I need is a pause function. I dare say
someone would have already created such a GX that when called pauses the
current GX for GetInt_SYS("GXPAUSE","MINUTES") period of time. So in the
spirit of collaboration, if someone sends me such a function I will send
through the completed _MAPPRINT2 GX. Otherwise if I don't get any reply in a
few days I'll have to do it myself. This will be difficult however since for
complex reasons I don't have a VB or VC compiler on my current machine!
Maybe a newbie could practise with this task (use a timer control), or an
experienced GX developer could whip it up in under an hour.
