QuickBasic Cafe Forum

I would be interested in what they are. But green on a blue background I cannot read!

When compiling QuickBasic programs there are sometimes cases that the compiler does not like. These include some calculations on double precision variables, and long strings. For example, 'FIRST' is not defined so the program will assume it is d.p. variable that takes up 8bytes. If the number is onl...

Can you show the routine(s) that include those lines of code so we can see the errors in context.

Here's an even simpler version.

hour$=left$(TIME$,2)
min$=mid$(TIME$,4,2)
sec$=right$(TIME$,2)

There is a library with good documentation called ADVBAS which you can download from here. http://pages.sbcglobal.net/oasys/dnldfr.htm It contains a routine 'Findfirsf' which if you supply a drive letter and suitable wildcards will find the first file in that range on the disk. Subsequent files can ...

The procedure in this program may help.

t$=time$
hour$=left$(t$,2)
min$=mid$(t$,4,2)
sec$=right$(t$,2)

Although there is an instruction to change a Hex number into a string, I can’t find the reverse function listed. I think you will have to use a simple routine. You need to go through the string, a byte at a time, using the mid$ instruction on consecutive pairs of digits to get numbers from 00 to FF....

NuKMAN, was that what you wanted?

I noted that your program had 30 records displayed on the screen as 10 rows of 3 records each. I didn't have your file to input from so I made up a sample one. I've tried to keep to the same layout. All 30 records are input from file into a fixed length string array - they are easier to manipulate t...

I'll come up with answers for you in a couple of days.

It depends on how you got the information on to the screen in the first place - which is why I asked you which file type you are using. I can think of at least 3 ways you could have written "100:job1" to the screen from data in a file, and how you deal with the data depends on that. If it uses a ran...

Is it a simple comma delimited file like this?

......,100:job1,200:job3,400:job6,...

Can you explain what you mean by

100:job1
200:job3
400:job6

Also does 'flat file' = sequential file?

You mention 10ms resolution. I don't know about VB, but with QB the best timer resolution you can get using 'Timer' function is 50ms. That's running under DOS. Running under XP or WIN98 it will vary between 50ms and 100ms. You can get much better resolution by counting passes through a FOR-NEXT loop...
