PureBasic Forums - English

Restored from previous forum. Originally posted by StSchnell.

Hello community,
at the moment I code a programm with access to the WinAPI. Now I have questions about handling with the API:

1. Is it possible to have the same access to constants of the API as to the functions, e. g. Sleep_(1000) calls the API function sleep, with WM_CLOSE_ or #WM_CLOSE I get the number 16?

2. Is it possible to use a special character for number in hex format, e. g. #SYNCHRONIZE = 1048576, but the API said #SYNCHRONIZE = &H100000. Okay, it is the same, but all API documents use hex format, can I use hex format too?

3. If I get an API function a string, and it needs a zero terminted string, is it necessary to use + Chr(0) at the end of the string or set it PureBASIC automatically?

4. Exist a function Not in PureBASIC, e. g. If i=1..., If Not i=1 or IfNot i=1?

5. Which debuglevel exist 0, 1, 2... or A, B, C... and what do each of them resp. what does it mean?

6. Is it possible to see local variables in the window of the debugger, without using the command Debug ?

Thanks for answers.
Bye
Stefan

Sure, just do:

WM_CLOSE_.l = #WM_CLOSE

at the top of your code. I doubt Fred would change how constants are access (with a # in front of them) as he has previously said he would not like to change things like that (I am specifically thinking of the structure\field separator, but they are both something which can be used to identify things in the language).

can I use hex format too?

If you put the dollar symbol in front of a number it makes it hexadecimal, e.g. $F00

3. If I get an API function a string, and it needs a zero terminted string, is it necessary to use + Chr(0) at the end of the string or set it PureBASIC automatically?

All PureBasic strings are zero terminated.

4. Exist a function Not in PureBASIC, e. g. If i=1..., If Not i=1 or IfNot i=1?

Not yet, but I think it is on Fred's list of stuff to do.

5. Which debuglevel exist 0, 1, 2... or A, B, C... and what do each of them resp. what does it mean?

If you mean the debug level of the Debug command then you use any number you want. It is used so that you can enable or disable how much debug output you get by using the DebugLevel command. For example if you have the code

Debug "foo",3
Debug "bar",6

And you set the DebugLevel to 5 then you will only see the first debug output. If you set the DebugLevel to be more or equal to 6 then you will see both.

6. Is it possible to see local variables in the window of the debugger, without using the command Debug ?

Not yet, again on Fred's list of stuff to do.

Hi,

A lot of small answers...

1. All Windows Constants can be easily accest from PB. Just put a # for Constant in front of it.
So #WM_CLOSE was just the right guess.

2. The Crarakter for this is '$'. So &H100000 in API is $100000 in PureBasic. (There is also the '%' Craracter if you want to use Binary Numbers: %11 equals to 3)

3. PureBAsic Strings are NULL terminated, so no need to add something at all.

4. There is only Bitwise not at the Moment it is the ~ character. I think logical Not is planned.

5. The DebugLevel are Numbers, from 0 to whatever you want. You can set different DebugLevels and then use the Debug Command also with a DebugLevel Parameter. This means, that this Debug Command will only be executed, if you program is in a certain DebugLevel.

6. No, that is not possible ATM

If you want to learn more about DebugLevel, look in the Help in the Debugger Section.
There is also more about the Operators in 'Variables and Types' Section

Hope that helps...

Timo

Logical NOT is planned and should be implemented soon (not for next release tough). The same the for the local variables in the debugger.
