I am new to ClearWin+ and have (at present) 2 problems:

PROBLEM 1:
I defined a window with three button options. First button enables
to choose an input data file, the second one enables to select an output data file, where the input data will be re-written in a new structure (format).

After selecting the input data file, the file name (including path) is displayed in the box below the button (which I required), when the output data file is selected, the filename is NOT displayed in the box below.

I don�t know why, since the code should be OK (see below).

Problem 2.
Third button is a combo, where I can select between two options, which are both CHARACTER*1 (z or b).

QUESTION: How can I find out what was selected and assign it to a variable in the main program, which will pass it to a subroutine?
I tried to write a call back function, however, I was unable to find, how to pass the selected answer (z or b) within main program to assign it to a variable, which will be passed to a subroutine

Below, my code of the main program follows (without subroutine, which works fine):

Thanks John!

I solved the problem with combo box selection (I did not notice the argument cur_item)!

However, I still have the first problem (when I select/define an output file, using OPEN_FILEW, the selected/defined variable file is not displayed in the required box (ans=winio@('%2nl%ta%ob%80st%cb&',s4) in contrast to the fisrt case, where when using OPEN_FILER, the selected variable is displayed in the requested box (ans=winio@('%2nl%ta%ob%80st%cb&',s3) ,

[Martin_K]

At the very beginning of the development I also tried to use FILE_OPENR for the output file name, however, this not worked, nothing was displayed in the prepared box for it. But I found that the use of OPEN_FILER does NOT allow to specify a new file name (which is required). Therefore I switched to FILE_OPENW. Now, I can specify a new file name l by typing in its name according to my will, however, this changes nothing in my problem - the prepared box, where the typed in output file name (including its path) should be displayed does not work as before (I see there only initialization name for the output file, which is .txt). So, I really do NOT understand, where could be a problem, since (apart from this) the program runs. I tried to debug it and I could see (under variable for output file name) the correct file name, which I typed in (including its path). Nevertheless - the box displays - as before - only string .txt (as originally initialized in the main program, regardless what I type in.

Hi John,

I would like to send the screenshot of the main window, however - how can I do it here? I see no attachment option here (for file attachments, as it is usual in other platforms). Is it the IMG ption([img]http://image_url[/img])? I am here (in this forum) totally new (a week), so please be a little bit patient and advise me. I could access my server, where you could download full description of my problem including all necessary files, if necessary.

Explanation to your question:
In the main window of the program I select three variables:
Variable1 - an existing data file (I use OPEN_FILER - it works, I see in the box prepared for displaying of the selection the selected filename including its path).
Variable2 - I used both FILE_OPENR and then FILE_OPENW to display the selected output file name TYPED IN by me (the file DOES NOT exists yet). The typed in filename is NOT displayed in the box below prepared for it (regardless what I use - OPEN_FILER or W), although the program works, creates the file specified by me and writes in the data in the requested format (more than 87 000 lines, each line consists of X,Y coordinates and their DX, DY variations)
Variable3: I can choose (in the combo box), whether I want to change the signs (+ or -) in front of DX, DY values to the opposite signs or NOT. Selection z stands for YES (in slovak language: change = zmena, therefore is there z). Selectionb is NOT for box, it stands for NO CHANGE in signs (in slovak: bez zmeny/without change, therefore you see there the option b.

Martin,

I have compiled and run your demo code as I couldn't at first work out what is going wrong. However, the issue isn't FILE_OPENW because if you change both of them to _OPENR or both to _OPENW, or one of each in either order, the first one works as expected and the second one doesn't.

The error is that in your callback routine sb_vstup4 you have the order of subor3 and subor4 reversed in your COMMON statement. So, if you change them round, the demo program works as intended. I have appended a cut down version of your program.

Many thanks Eddie!!! Now it works fine. I reviewed my code 100x, but
was unable to catch the reversed order! Again - many thanks and best wishes!

Thanks again Eddie!

I already registered, so next time, when I will have a problem and some images will help to solve it, I will post them there!
