I want Enter/Return key from keyboard to be ignored in a Widget_Text 1324 1
Started by Deleted User
I have a Widget_Text item that is editable. If the user edits the values in the text box then it is detected and the necessary steps are taken. If the user hits the Enter key on the keyboard the program crashes because it does not know how to handle that input. I want to be able to disable any input from the Enter/Return key from the Keyboard. How can I do this
Thank you.

Starting with IDL 1538 1
Started by Deleted User
I am working in the area of target detection. I often require to transport images in the GeoTiFF format to MATLAB. I wish I could work in IDL. May someone give me a basic tutorial so that I can open an image in IDL and start writiing programs so that I can handle the images here itself.
Secondly, I am not able to open ENVI img file format in ERDAS. In which format should I save so that I can open it in ERDAS

Controlling program after an error 1549 1
Started by Deleted User
I'm calling the function maximization routine, DFPMIN to analyze pixels in MR images. Occassionally the routine reaches the limit of the number of iterations. I'd like to put
in some error value into my image and continue with the next pixel. I don't see a way
to have the program acknowledge an error has occured and continue on.
