Hi David,
I Installed a program that use Dplot jr, in Pc.
when the program started for the first time, dplotjr is opened unhidden, and after the first use, it starts normally(hidden).
Even if I uninstall the program, and delete all references to dplotjr in the registry, if I re install the program, i don't have the same probleme!!!

it was tested in 3 systems Vista, XP, and sever 2003.

I use this code(VB) to start Dplot:

Code: Select all

Dim Ret As Long
Ret = DPlot_Start(1, Ret)

I'm not getting the same results here, but I think this is likely a problem with the settings file %APPDATA%\DPlot\dplotjr.ini. If you delete the file, then run your program, does the same problem occur? My guess is yes.

One more question: What anti-virus program are you running? The reason I ask is an older version of McAfee I previously used slowed down writing files to %APPDATA% by quite a bit - apparently it thought that folder could be used for something nefarious. If that's what is occurring it could explain the problem - DPlot Jr is maximized by default until you change that setting. But "maximized" and "hidden" don't get along well, so when you try to start the program hidden, DPLOTLIB.DLL writes a line to dplotjr.ini that tells it not to start maximized. It's possible that the file is not updated before dplotjr.exe is started.

I deleted the ini file, but the problem didn't occur!!!

I m' not running any antivirus, it's an empty pc, just the operating system, and my program.

It occurs, when i delete the path %APPDATA%\DPlot\, not just the ini file.

Ah! That's a good catch, thanks.

I'll fix this in the next release.

I've uploaded new DLL's that correct this problem. The standard stdcall version is available from http://www.dplot.com/lib/dplotlib.dll. The cdecl version is at http://www.dplot.com/lib/dplotlib_cc.dll.

In these versions the %APPDATA%\DPlot folder is created before running dplot.exe or dplotjr.exe if that folder does not already exist.

Thanks for pointing out the problem, and for your good detective work!
