  2. Re: CreateProcess failed with ERROR_ACCESS_DENIED

    Hello Arjay,

    all the parameters of cp are in my hands.

  4. Re: CreateProcess failed with ERROR_ACCESS_DENIED

    Hello,

    si was initialize exactly like in your snippet.
    pi not, but why?
    pi is an output parameter, it should be filled by CreateProcess.
  5. Re: CreateProcess failed with ERROR_ACCESS_DENIED

    @2kaud:
    my snippet shows only the call.
    I do it with
    if(::CreateProcess(...))
    {
    ..
    }
    else
    {
    // error
  6. Re: CreateProcess failed with ERROR_ACCESS_DENIED

    win10, 64-bit. Sorry.
    It is ::CreateProcess and buffy is the commandline which holds the name of the calling app. The calling app is also from me and creates a new window to show something.

  8. Re: How to call CreateProcess and Waitforsingleobject/ MsgWaitForMultipleObjects?

    Hello Igor,

    there is no special communication needed.
    But it will be good if the main app waits until the new app shows its window.
    What is needed for that?

    thx.

  20. Re: Change item height in CListBox / CListCtrl

    PreTranslateMessage is called, if VK_DOWN etc. is stroke.
    and IsDialogMessage says that the WM_KEYDOWN-message has been processed. But where?
  21. Re: Change item height in CListBox / CListCtrl

    yes.
    Now, I checked it with Spy++.
    A WM_KEYDOWN-message was sent to my ctrl-window!
    But no WM_KEYUP-message????
    Maybe this goes to another window?
    If I strike VK_SPACE, I get a WM_KEYDOWN,...

  23. Re: Change item height in CListBox / CListCtrl

    Hello again,

    it has nothing to do with the styles.

  25. Re: Change item height in CListBox / CListCtrl

    yes, I set the notify-property for the static-control in the dialog-editor.
    I think, this is the same as SS_NOTIFY?!
    Without this there was also no call to OnLButtonDown().
