In MS Access is there a way to allow forms to update while maintaning Read Only -

-

I have several forms of linking tables through questions by selecting a product from the main form combo box And draws data such as data.

I still have problems:

1- I would prefer the combo box for a free entry at the end; However, entering the box and entering the entry (there is no button called "insert on a screen", which will initiate the recess, only the normal will be recorded), while it brings new information to the sub-form, Also changes the table. If I read the table only then it does not allow me to work by saying that the table is for reading only.

2- The same problem reads only when another user tries to use the database only to read

I understand I am only working for the purpose of preparing, although I am thinking that some functions are a way of working while allowing updating.

I am learning on a journey unfortunately, so go easy plz

thank you

You need to link your combo box to the underlying data, but after the data has changed, set / reset the value of the combo box. In this way, if some sort of a new value is a) This data will not update or not, whether it is updateable or not.

B) You can still update the subfomes based on this value 

  private sub form (cmbMyDisplayOnlyComboBox = Me! WhatEverFieldHasTheValue End Sub

Again, the cmbMyDisplayOnlyComboBox control source is empty. Use the field that 'use' can be in the form of a control source, such as the EverFields

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
