    Lance,
    I've sent you already my thanks by e-mail, but want to do it here as well. Indeed the routine fell in an endless loop, due to the fact that its params were not declared 'BYVAL' and so the original variables became modified.

    Stupid to forget these basic BASIC-things.
    Sorry for stealing your time and thanks again.
    Problem solved!

    Egbert, the problem with your code is that one of your callbacks calls the function...

    FUNCTION JaargangNummer(begin AS LONG, final AS LONG) AS LONG

    ... and this function sometimes gets stuck in an infinite loop. This "freezes" the app, because the callback never terminates.

    Lance,

    I've sent you the code by e-mail. The app. is too large to publish it here. In the meantime I've modified the callback for the buttons. There is one BtnCallBack now, using btnMsg = CBCTL, followed by a SELECT CASE. This does not solve the problem, however.

    For the time being I've made a criple workaround. After clicking on one of the buttons both are disabled. The only thing the user can do next (and finally) is clicking on the OK-button to end the app. Not very elegant, is'nt it?

    Regards and best wishes for the final year of this 999 years old millennium.

    problem with buttons and labels

    Compiler PBDLL60
    I've a dialog, containing 3 text labels and 3 buttons.
    One button serves to end the dialog (OK-button). The other two are supposed to place text in 2 of the 3 labels. Those labels are empty on start-up. After clicking one of the buttons for the first time, the supposed text correctly appears in the labels. Then clicking the other button, only one of the 2 labels shows up with different text and then the application hangs. Even the OK-button does not work anymore, nor does the closebox in the right upper corner of the window, so I'm forced to use Task Mananger to end the app.

    Someone having any idea of what can be wrong? To be more specific: I'm using 3 different callback functions for each of the buttons plus a general call back to initialize the dialog.
