carriage return 2400 0
Started by Deleted User
I am trying to get a carriage return that returns to the beginning of the CURRENT line, a la the '\r' character in C. I see how to get C-style formatting to work in other respects, but this particular character doesn't work (it behaves as the '\n' character). I am using IDL 5.4 on Win2K.

Redirect standard output 2522 0
Started by Deleted User
Dear all,
I build an IDL widget interface to control three C programms which evaluate our data. When these programms were developed we spent much time in an accurate error handling because of these programms deal with web access to a database and so on. Now I want to give the user the posibility to control the actions taken by these C programms from my IDL interface which later will plot the data. Therefore I tried to show the output of my C programms (which is send to stderr in the programm...

color animation with IDL 2519 1

I have tried to make a movie from my time resolved

Although the colors are quite OK when creating
.GIF or .PNG images from the plots, the colors

movie rather useless when translated into the
mpeg format.
I have gone through various more obvious possibilities with the tech. help center, but nothing works. (I think it is not a windows or 24-bit problem, since .gif and .png images displayes and reproduces correctl...

Help with writing HDF4 files 2439 0
Started by Deleted User
Hi. I've run into problems writing HDF4 files and would appreciate help from anyone with experience. I would like to create one Vdata and have it contain multiple fields. I've sucessfully created the Vdata and named the fields using HDF_VD_ATTACH and HDF_VD_DEFINE but when my code reaches the various HDF_VD_WRITE it generates an error as it tries to write to the various fields. I'd appreciate any help on how to accomplish this.
thanks.

Color table on Win 2000 and XP 2106 1
Started by Deleted User
I find it aggravating that I must drop the color table back to 256 colors to use plot, tv or tvscl when running in 32bit color mode on Win 2000 or XP.
This is probably on old question but is there a better way to map the color tables for making simple plots and using tv than dropping back to a 1987 video mode. Matlab doesn't require this, and this should be a default mode in IDL.

Running out of file handles 2348 1
Started by Deleted User
I am processing a large number of files, I am opening both ENVI image files and regular IDL files. According to the manual, the ENVI_OPEN_FILE procedure does not actually use a file handle except when it is actually reading or writing a file. I am writing object style IDL opening and closing my IDL files in the same method. Why does my program die with the message it is running out if file handles

Creating array of objects in subobject 2085 0
Started by Deleted User
I have an object that I want to have hold an array of subobjects. I have been trying to use objarr for this purpose, but the IDL manual is pretty thin on how to use it. The containing object references a file. Each element of the array it contains holds the elements of a line of that file. See sample code below does not work.
I don't know how to assign address of 'note' to element of objarr.

One day offset error in JULDAY function 1971 0
Started by Deleted User
There seems to be a one day offset error in the JULDAY function which is expressed below for New Years (Midnight) minus 1 second on 12/31/1999
IDL>print,JULDAY(12,31,1999,23,59,59)
2451544.5
The CALDAT proceedure yields:
IDL>CALDAT,2451544.0,m,d,y,hh,mm,ss
IDL>print,m,d,y,hh,mm,ss
12 31 1999 12 0 0.0000000
but the Julian date listed in the Astronomical Almanac is: 12/31/1999 23:59:59.9999...= 01/01/2000 00:00:00 as 2451543.5
This one day discrepancy is very important...

Hi,
I'm running IDL 5.6 on Windows XP.
I have discovered the usefulness of LIVE_PLOT in comparison with PLOT and started fooling around with the settings to create personalized plots. In an attempt to delete the plot-windows, I gave the command:

That was obviously a bad idea: ever since, LIVE_PLOT refuses to work, generating the error message:
'Error occurred in LIVE_PLOT. Unable to invoke method on NULL object reference: OWINDOW.'

interrupted system call during socket communcation 2128 0
Started by Deleted User
Hi there,
I'd like to have a button to start the socket communication server. The event handler for that button calls a c routine. The IDL GUI doesn't have any timer widgets. But the accept function in the c routine is always interrupted by some system call. I am very confused about where the interruption signal comes from. Does anyone have the solution Thanks a lot.
