If you want to work in the program with a data file, you have to open it first.
The file can be opened in three different ways:
Using a dialog window
Using a parameter when starting the GROMA program
Dragging its name from the Search Engine.
The most common way how to open a file is using the dialog window Open File.
When choosing the command File->Open, GROMA program will display a dialog window to select a file.
Select the required file type from the list Files of type. If you import the measured data list from a field book, first you have to set the field book type and format in the dialog window Settings->fieldbook. According to this setting, the selection of file types on the list Files of type will be updated.
Select the pertinent disc and directory from the list Where to search.
If the file you want to open exists, its name will appear in the list. Highlight it using the cursor or the mouse or keyboard. If you want to open more files at once, highlight them in the list using the keys <Shift> and <Ctrl>.
Press the button (Open). If the file exists, GROMA program will open it and display it in the window.
If you write, while starting the GROMA program, a name of one or more data files behind the program name, the program will try to open them automatically after its launching.
If you have launched the Search and also the GROMA program, you can open the data file by simply dragging its name from the list displayed in the Search to the desktop of the main window of the GROMA Program. When dragging, the appearance of the cursor changes according to the area where it is located at the moment. You can find details in the MS Windows User Manual.
If you work in the computer network environment, it can happen that you want to open one file from the shared disc (e.g. from a server) on more computers at once. This situation is common, for example, while working with joint coordinate lists containing points of a point field. Usually, a file is open for reading and writing. In this case, it can be opened only once, because to write in one file from more stations could result in its defecting. The program will notify you of such situations and will not allow you to open a file already opened for reading and writing.
But if you check, using the command File->Open, the option Reading Only while opening the file, the list is opened only for reading. In this mode it can be opened by an arbitrary number of users. If you try to open a file in regular mode, i.e. reading and writing, that is already opened in this way, the program will notify you that the file is already open and will offer you the option to open the file for reading only.
No changes can be made to a file opened for reading only, but you can use the stored data. The user can, however, copy the items of the file into another file where there are no such limits.
File opening for reading only can also be used if you work with the file by yourself, but don't want to change it. In this way, you lower the risk of damaging valuable data files.
