Re: [Gambas-user] Gambas API of ALSA

Thank you very much.
Now the problem is how I can use those information with Gambas !!! :-(
I would interested too in writing a midi librarian for my keyboard, but
leaved this idea behind because I am too busy these days. I wrote a
working one under windows, but now I would need a linux version. So, if
you succeed in doing something, let me know.
If I well understand, you want to send data to a midi device. It seems
that you can do it in two ways - using the filesystem, or using the alsa
library.
In the documentation from:
I guess you can find some answers here, thanks google!
https://ccrma.stanford.edu/~craig/articles/linuxmidi/
there are several C sources, which can be translated more or less to
gambas. The simplest of them is:
int main(void) {
char* device = /dev/midi ;
unsigned char data[3] = {0x90, 60, 127};
// step 1: open the OSS device for writing
int fd = open(device, O_WRONLY, 0);
if (fd 0) {
printf(Error: cannot open %s\n, device);
exit(1);
}
// step 2: write the MIDI information to the OSS device
write(fd, data, sizeof(data));
// step 3: (optional) close the OSS device
close(fd);
return 0;
}
This code (output/method1.c) does something very simple - it write three
bytes to the file /dev/midi. You can try from console using something like:
cat myfile /dev/midi
where myfile has a suitable content, like 0x90, 60, 127, which in
gambas translate to h90, 60, 127.
If you only want to send out some midi data, this approach seems to be
effective and easy: just open a file for output, and write some bytes to
it (you must know what to write - this is a different problem). If you
want to make your device play, you will have to output several 0x90
0xXX 0xXX (note on event) followed by 0x80 0xXX 0xXX; accurate timing
will be an issue.
The device /dev/sequencer does similar things, but is more intelligent
and can do good timing.
Alternatively, you can use a library like alsa. You must use External
function declaration in gambas, and you will have access to the power
of alsa. This is not easy, but possible; in this case, you must know a
little the C language.
To summarize, think at what you want to do and choose one of the three
methods: /dev/midi is poor and simple; /dev/sequencer is more
complicated but still easy in gambas; using alsa (OSS is older) is the
way to go if you want to do a complicated but powerful program.
Let me know if you have more doubts. I have no time to write a program
myself, but I can find some time to give you some hint. Please specify
more precisely what you want to do.

Doriano

Re: [Gambas-user] DataSource component - Is it works with postgresql's schemas? - Gambas2
I wish to know, if the DataSource component works with postgresql's schema, because I try to use it and don't work. I modificated DataBase Example, changed in the DataSource2 property, table : color = test.color, test is the schema's name and in the other DataSource1 I changed Table :test = test.test. I get this error = Unknown table test.color Regards Jorge Amarilla Postgresql schemas are supported in Gambas 3 only!

Re: [Gambas-user] Feature request
I wondered if there was any easy way to find a file (class/form/module) in ones code tree. Maybe this feature already exists in gambas3 As I've hundreds of forms, classes and modules, I've got to the point where I occasinally 'mislay' one. Yes I know I can search my HDD easily with locate, but it would be a nice feature to be able to type in a name jump to that subdir with the file. Regards Richard I note that in the TODO file! -- Benoît Minisini -- ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

[Gambas-user] Help with redirecting stdout of the GNU shred command (SHELL/EXEC)
Hi, I am new to Gambas and this is my first application. I have been working with C/VC++ and Gambas has been fun so far except for this little problem i've run into... I am trying to make a GUI front end for the GNU shred command. I have got to the stage where the user can select a file via GUI and shred(using SHELL). I am trying to make it more interactive by reading stdout from shred -v into the Gambas application. I have followed http://www.gambasforum.com/index.php?topic=120.0;wap2 and tried to use EXEC to read stdout, haven't had much luck with it so far :( Heres the code: 'global variables PRIVATE filename AS String PRIVATE delfile AS Boolean PRIVATE shredprocess AS Process PRIVATE shredcommanddel AS String[3] PRIVATE shredcommandnodel AS String[3] 'this is where i initialize the command arrays for EXEC 'the last element is replaced later by the filepath PUBLIC SUB Form_Open() 'tbx_filename shredcommanddel = [shred , -uv , ] shredcommandnodel = [shred , -v , ] END 'Display a file open dialog and save the path of the file selected to filepath PUBLIC SUB btn_fileselect_Click() IF Dialog.OpenFile() THEN RETURN filename = Dialog.Path tbx_filename.Text = filename END 'the actual shredding happens here, the code with EXEC is ineffective at the moment it doesnt shred the file 'SHELL works, but i dont know how to redirect stdout with either of these PUBLIC SUB btn_shred_Click() 'DIM shellcommand AS String[] 'Message(filename) IF delfile THEN 'shellcommand = shred --remove --verbose filename shredcommanddel[2] = filename shredprocess = EXEC shredcommanddel 'FOR READ SHELL shred -uv filename ELSE 'shellcommand = shred --verbose filename shredcommandnodel[2] = filename shredprocess = EXEC shredcommandnodel 'FOR READ SHELL shred -v filename ENDIF 'SHELL shellcommand FOR READ AS Process END 'Execution never gets here PUBLIC SUB Process_Read() DIM resultline AS String LINE INPUT #shredprocess, resultline Message(HERE WE ARE!) resultline = resultline GB.NewLine END PUBLIC SUB CheckBox1_Click() delfile = TRUE END I am looking for a way to redirect output from the shred to my Gambas application.
