Re: Confused about substacks

[Mike Bonner]

Probably what will work is to make a stackrunner type of splash stack with
any libraries etc included. Then you can have your real stack with its
substacks be opened by the splash. As long as the right support stuff is
included the splash you can "go stack.."  and it should be fine, and the
splashstack can handle the saving of changes to your real stack.

Re: Confused about substacks

Correction. You cannot go to a card in a new window. The command will ignore 
the new window and just go to the card in the existing window. That would be a 
nice feature enhancement for having multiple windows open on a single stack.

Re: Confused about substacks

[Bob Sneidar]

Oic. Because if they are substacks of the splash stack then they are part of 
the standalone and therefore not editable. That makes sense. I think I am 
misusing substacks then. I should just make them individual stacks on the hard 
drive. The goal is to have multiple editable forms open at the same time, so 
having each form as it's own stack seemed a logical choice, but now I am not so 
sure. I wonder if I should just be using go card in new window instead?

Re: So Who Has Tried the Kindle Fire Yet (with LiveCode building)?

[Colin Holgate]

Not exactly that, but all of the elements of what you said.

I did wirelessly download several apks to the Fire by touching the url to the 
apk in an email message. As with all Android devices, that downloaded and 
installed the app. You do have to go to settings to allow installs of apps from 
places other than stores first. Those apks happened to be Flash ones, but 
there's no reason to think that any other apk would behave differently.

I also did tests from LiveCode, with the device connect by USB, and that worked 
fine. And I did tests from Flash, to the connect USB device, and that worked 
fine too.

There was one particular thing I had to do in order for it all to work, which 
was to add the value 0x1949 as an extra line at the end of the file 
~/.android/adb_usb.ini

With other Android devices, at least with Android 3.x, you have to go into 
settings and Developer, and specifically turn on the feature that allows 
debugging over USB. With the Kindle Fire that is on by default, and there isn't 
a setting to turn it off.

Re: Confused about substacks

[Mike Bonner]

Assuming you are doing this so that you can save your stack file, yes. When
you make a stack a substack, I do believe it incorporates it all together.
However, there is a setting in the standalone builder that avoids this when
you build a standalone. Its under the stacks heading, "move substacks into
individual stack files."

Re: Confused about substacks

[Devin Asay]

Hi Bob,

When you turn a mainstack into a substack of another mainstack, that substack 
becomes part of the stackfile containing the mainstack. In effect the stackfile 
containing the former mainstack is "orphaned". Usually I just get rid of these 
orphaned stackfiles to avoid confusion. 

Bottom line: substacks are part of the same stack file of the mainstack.

Hope this it what you were asking.

Devin

Confused about substacks

[Bob Sneidar]

Hi all. 

I am a bit confused now. I created a new stack, saved it, made it a substack of 
my splash stack. No problemo. I can see the substack on the hard drive, I can 
see the substack in the application browser as a substack of my splash stack. 

BUT THEN...

I right clicked my splash stack in the application browser, and created a new 
substack, named it, saved it, application browser looks peachy, but the stack 
file is not visible on the hard drive! Does making a stack a substack create a 
COPY of the original stack and imbed it in the main stack, or is the file 
hiding somewhere else on my hard drive? If the former, then am I correct in 
thinking I do not need the other stack files I CAN see on my hard drive, 
because there are now copies of them in the main stack?

I am s confused...

Making an existing stack a substack of another

[Bob Sneidar]

Never mind I found the command. You set the substacks of the splash stack to a 
list of the substacks you want. Odd that the menu option does not work though. 
Seems that is still a bug.

Making an existing stack a substack of another

[Bob Sneidar]

Hi all. I am doing things bass ackwards as usual. I created my main application 
stack, and now I want to create a splash stack and make my main application a 
substack of that. I know about the popup menu in the Stack Properties. I set 
that to the splash stack in my main application stack, then save both stacks 
but I can see in the Application browser, the change is not taking effect. The 
splash stack is still it's own stack and the main application stack is still 
it's own main stack. 

I hope that is not too confusing. Have I fallen on to a bug here?

Re: Data Grid Challenges

[Michael Doub]

I would like to share some of the wisdom of Zryip The Slug (ZTS) as it may be 
of some help to others not the list.


For the Color problem:
ZTS:  If you have the need to change the color of the background rectangle of a 
row and not want to use the row color property of the datagrid, you have to 
rename the rectangle object. Internally the datagrid engine applies the 
properties set for the row color to the rectangle "background" it finds in the 
template.

MD:  This is vert subtile.  It looks like best practice would be to always 
change the name of any controls that you would like customize.


For the Row height issue in GetDataOfLine mode:
MD:  Don't seem to have root cause yet but ZTS offered the following work 
around:

on OpenCard
   lock screen
   set the dgNumberOfRecords of group "Contacts" to 20
   set the dgProp["row height"] of group "Contacts" to 34
   unlock screen
end OpenCard

By setting the row height property of the dagrid group to 34, all is ok.


And of coarse I made THE CLASIC behaviour mistake in my testing code.
set the rect of graphic "Background" OF ME to x

ZTS:  Never forget to refer to OF ME when you are referencing an object in the 
behavior script.

Thanks again to Zryip, his help is much appreciated.

Regards,
Mike

Re: Database Strategy

[Bob Sneidar]

If you are working with cursors, my personal preference is to parse the data 
from the cursor, and then close it and forget about it. If you need new data, 
requery the database. 

I have mentioned before on the list that sqlYoga has functions for querying a 
database and returning an array that is compatible with datagrids. By passing 
that array in setting the dgData (set the dgData to aQueryArray) you have a 
very simple way to populate the datagrid without any of that messy parsing. 

sqlYoga is well worth the price for anyone doing serious database work in 
Livecode.

Re: DataGrid Speed

[Bob Sneidar]

I think I understood him to say he would build his own array and then populate 
using dgData. My personal preference, once I understood what datagrids did with 
arrays, is to always use arrays when I can. sqlYoga returns datagrid compatible 
arrays, so you can get a data set through a query, and then set the dgData of 
the datagrid directly. Very handy. 

However, if the initial population of the datagrid is underway, and your data 
is already delimited text, just use dgText and let the datagrid library handle 
building the array for you. After that you can work with row elements as needed 
by accessing the various datagrid array functions for doing that. 

Maybe I didn't understand the question though.

Re: DataGrid Speed

[Bob Sneidar]

If you use dgText, the datagrid library will create the array internally, 6 one 
way half a dozen the other, except that the datagrid library knows how to do it 
right. But if you have an array already, then using dgData is of course 
quicker.

Re: So Who Has Tried the Kindle Fire Yet (with LiveCode building)?

[Colin Holgate]

I ordered it a few days ago, I guess they had plenty of stock. 

One of my email buddies arrived home to find an empty space outside his front 
door, where his Fire had been delivered. Hopefully yours will be alright.

Dang, Colin-- that was FAST! Thanks for the update. I've been travelling
all week while mine is waiting at home. It will be in my grubby hands in a
couple hours!

Also, I'm about 3/4 through the Steve Jobs bio. Good read, for those of you
who haven't checked it out.

Re: Location of dialog box

[Ken Ray]

> Ken--I was referring to the stack that opens in response to the RR "Answer" 
> command. Is it possible to set a preopencard handler in that stack?

Yes, but for the reasons that Wilhelm wrote you wouldn't be able to distribute 
a raw stack to someone else and have it work right in their IDE.

I *DO*, however, have a workaround to this that seems to work in my tests:

1) In your stack create a hidden button (I called mine "AnswerLoc") with this 
script:

global gAnswerLoc
on preOpenCard
   if the short name of this stack is "Answer Dialog" then
  if gAnswerLoc is not empty then
 set the loc of stack "Answer Dialog" to gAnswerLoc
 put "" into gAnswerLoc
  end if
   end if
   pass preOpenCard
end preOpenCard

2) Sometime before you call on "answer" for the first time, insert the script 
of that button "into front" to make it a frontScript:

insert script of btn "AnswerLoc" into front

3) When you're ready to call on "answer", set the global gAnswerLoc to the loc 
you want the answer dialog to appear at, and then call "answer":

global gAnswerLoc
on mouseUp
   put "100,100" into gAnswerLoc
   answer "Hello"
end mouseUp

This will give you the desired effect, it cleans up after itself nicely, and is 
completely distributable.

Read From Socket Question

[Warren Kuhl]

I am trying to retrieve data from a socket.

When I try:

read from socket myDevSock for  characters
put it into tData
...I get data

read from socket myDevSock until crlf
put it into tData
...I get data

read from socket myDecSock until eof
put it into tData
...no data

Wouldn't the read until eof pull in all data that is passed back?

Thanks for any help!

Data Grid Challenges

[Michael Doub]

I am trying to understand what is going on with data grids.   I have a stack 
with 2 cards each with a different data grid.   One is set up to have the card 
script populate the grid using the GetDataForLine technique the other sets the 
dgData property of the grid.   Below you can see the techniques used.   The 
data grids were set up manually but are identical in that the backgrounds and 
background boarders are set to different colours but with the same height of 
35.   Both data grids are set to fixed height of 34 to overlap the boarder to 
only see a single boarder between rows.

There are 2 mysteries:
1)  The the grid on each card,  the colour of the row backgrounds are always 
set to white.  Not at all the colour of the template.  However, the colour of 
the row background boarders are set copied correctly from the template. 

2)  The second mystery is that the card using the GetDataForLine technique has 
two other problems.  The data is correctly being populated, but the row hight 
is set to size of the default template or 21; not the size of the edited 
template. With this incorrect size the slider does not work.  If you go into 
edit mode, then refresh the DataGrid the sizes are adjusted correctly, return 
to execute mode then the scrolling works properly.

I would really appreciate some help on this one.   There must be something 
really basic that I am missing.  The actual stack is here: 
http://dl.dropbox.com/u/43797494/test.livecode

Regards,
   Mike



Card 1  ---

on OpenCard
   lock screen
   set the dgNumberOfRecords of group "Contacts" to 20
   unlock screen
end OpenCard

on closeCard
set the dgData of group "Contacts" to empty
end closeCard

command GetDataForLine pLine, @pOutData
   put "This line is : " into pOutData["FirstName"]
   put pline into pOutData["LastName"]
end GetDataForLine


Card 2  ---

on OpenCard
   put empty into tdata
   repeat with x = 1 to 20
  put " This is a test record: "into tdata [x]["FirstName"]
  put x into tdata [x]["LastName"]
   end repeat
   set the dgData of group "DataGrid" to tdata
end OpenCard

on closeCard
set the dgData of group "DataGrid" to empty
end closeCard


Both data grids have the identical behaviour scripts. 


on FillInData pDataArray
set the text of field "Label" of me to pDataArray["FirstName"] & 
pDataArray["LastName"] 
end FillInData

--left top right bottum
on LayoutControl pControlRect
   local x
   put  pControlRect into x
   put item 2 of x + 35 into item 4 of x
   set the rect of graphic "Background" to x
end LayoutControl

on ResetData
set the text of field "Label" of me to empty
end ResetData

I think this needs to be implemented on the engine side /like ASK and ANSWER

Re: Location of dialog box

[Wilhelm Sanke]

Addendum to my last post in this thread:

I have used this approach for dialog stacks with the added "newloc" 
property in many of my stacks, e.g.


look at the scripts of buttons "Store image 1" and "Store image 2" in my 
stack "seamless tiles".




This stack contains the Metacard answer dialog as a substack, and works 
fine in the Livecode IDE, too (tested with version 4.6.4).

Wilhelm SDanke

Re: lc shell and command line

[Andre Garzia]

Guys,

As far as I know, you can't ask for the user password and pass it to a
shell call with clever use of pipes. That is not how sudo works, you can't:

 cat password.txt | sudo cd ..

or

  sudo cd .. < password.txt

The only way I found to script sudo calls is by using expect (
http://www.nist.gov/el/msid/expect.cfm ). Expect is a tool to automate
interactive console applications. You can craft an expect script that call
sudo and whatever else you want to do and call that script with shell().

 I might remind you - and especially Ken as the present chief of the 
Metacard group - that we have long implemented such a feature for the 
ask and answer dialogs in the alternative Metacard IDE, following a 
proposal from my side several years ago.


At the end of the preopenstack handler of the dialog stack (in the card 
script) we have added two lines of code:


" if the NewLoc of this stack is not empty then set the loc of this 
stack to the NewLoc of this stack

  set the NewLoc of this stack to empty"

In the script calling the dialog you have just first to set the "Newloc":

"set the newloc of stack "answer dialog" to x,y"

or use globalloc alternatively.

The second line of code above "set the NewLoc of this stack to empty" 
makes sure the dialog will pop up at the "normal" loc when no Newloc has 
been set before calling the dialog.


This approach is so simple! I have always wondered why the Livecode guys 
did not include such a simple solution in the Livecode IDE, too.--


These two line of extra code could of course be added to the 
revanswerdialog etc., too, but then, when you distribute a 
non-standalone stack, without prior including the answer dialog as a 
substack, it will not work with the Livecode IDE of another user. On the 
other side, with an answer dialog embedded as a substack you might run 
into troubles, because the Livecode IDE is very special with double 
stacks and might throw an error (Did not test this with the last version).


Best regards,

Wilhelm Sanke

Re: lc shell and command line

Regarding shell commands and LiveCode

I've noticed that under OS X, invocation of a shell command is silent.  But 
under Windows, you see a CMD window quickly pop up and disappear.  I haven't 
found any options to prevent the shell command popping up under Windows, but 
wondered if anyone knew of a way to prevent it from happening.  

Thanks,
John

Re: Location of dialog box

[James Hurley]

Ken and Malte,

Thanks for the suggestions. 

Malte--Your suggestion works well. Thanks. As you say it is a bit of a hack. 

Ken--I was referring to the stack that opens in response to the RR "Answer" 
command. Is it possible to set a preopencard handler in that stack?

But using a modal stack as you suggest, I can roll my own "answer" dialogue. 
This would give me more flexibility. I assume many others take this route.

Thanks, again,

Jim Hurley
