Can someone help me with a programming problem, I'm not a great programmer
and I can muddle my way through but this has me stumped as I don't know how to
make it work.
It has been suggested that you can start a subroutine in many ways and this
might just be my problem so here is a little about my problem and hopefully
someone can e-mail me and tell me how to make it work.
I am trying to locate a device on the USB chain, I know it's VendorID and
ProductID, I have fields in a nib for text mesasges, and I use the "IBOutlet id
textField" in my header file.
It appears that I can do a [textField setStringValue @"a message"]; in some
places but not in others.
OS 10.2.8
Project Builder 2.0.1
Component versions
PB IDE: 99.3
PB Core: 99.1
ToolSupport: 97.0

example of a location not working..... (errors on build)
Foo.m
--------------------------------------------------------------------------
void DeviceNotification( void *refCon, io_service_t service, natural_t
messageType, void *messageArgument )
{
kern_return_t kr;
MyPrivateData *privateDataRef = (MyPrivateData *) refCon;
if (messageType == kIOMessageServiceIsTerminated)
{
printf("Device 0x%08x removed.\n", service);
[textField setStringValue @"Device was removed.\n"];

FILE *fil = fopen("/var/flexlm/aw.dat","w+") ;
if ([self mygethostid]){
setupbuf(4,5000) ;
if ([self printresult: fil major:4 minor:5000]){
setupbuf(5,0000);
if ([self printresult: fil major:5 minor:0000]){
[textField setStringValue: @"Key generated successfully!"
];
}
}
}
if (fil)
fclose(fil);
}

Anyone know how to solve my problem, I invite you to correspond directly to
me at email@hidden.
Trying to learn a new programming environment has it's ups and downs, this
for me is a down cause it's probably something really simple.
