current card?
Hi all, Does anyone know of a property that will tell me which card is being shown in an open stack? something equivalent to the current card of stack s? If there is not a property (I haven't been able to find one yet) does anyone have a good suggestion for finding this?

How to create large XCMD / DLL with callbacks
I need to create an XCMD and DLL with several tricky characteristics. While I have created Macintosh XCMDs before, I am not sure how to deal with this set of characteristics. Also I have not dealt with DLLs for PCs so I am unaware of issues that may arise. Any insights or references to code that does the job would be much appreciated. 1. The XCMD / DLL must be substantially larger than 32K. So, at least for Macintosh, I have to create an XCMD that loads the larger block of code into memory and then calls it. Also, perhaps it is best to leave the loaded code resident in memory until MetaCard quits (or my MetaCard stack closes), because the XCMD / DLL will be called repeatedly. 2. The XCMD / DLL must allocate large amounts of memory (several MB), to be maintained even when the XCMD / DLL is not in use, and de-allocated when MetaCard quits. I have done this previously on the Mac, but I haven't learned how to do this on PCs. 3. The XCMD / DLL must set global variables in MetaCard, and ideally could make other callbacks to MetaCard. CodeWarrior comes with some sample projects that discuss issues 1 and 3, but they take some work to understand (indeed no sample project incorporates both characteristics 1 and 3) and to be honest I haven't understood yet. I was thinking of programming in CodeWarrior C (I have version 3.2), though I could switch to different software and/or programming language if that would help. If anyone has a template or sample code, ideally with at least characteristics 1 and 3, you could be my savior. Thanks in advance, Ken This is the MetaCard mailing list.

Also, perhaps it is best to leave the loaded code resident in memory until MetaCard quits (or my MetaCard stack closes), because the XCMD / DLL will be called repeatedly. You don't necessarily have to keep the XCMD under 32k, if you can afford to be PPC-only. I've had much larger XCMDs before, and they work fine. I'm not sure what Metacard's policy is as far as keeping XCMDs in memory however- it's my feeling that they will stick around if you have sufficient memory allocated, but someone more in the know would have to to answer that one for sure. 2. The XCMD / DLL must allocate large amounts of memory (several MB), to be maintained even when the XCMD / DLL is not in use, and de-allocated when MetaCard quits. I have done this previously on the Mac, but I haven't learned how to do this on PCs. What about just malloc() - ing the memory in your XCMD/DLL, and saving the pointer to a Metacard global? Then add de-allocating code to your XCMD/DLL's cleanup routine which fetches those values and releases them. 3. The XCMD / DLL must set global variables in MetaCard, and ideally could make other callbacks to MetaCard. For XCMDs, Metacard support the standard XCMD SetGlobal/GetGlobal callbacks, and for DLLs you can find the whole list of callbacks in the file "XCmdGlue.h" in the folder "MC External Data" that comes with the Metacard distribution. There is sample code in the file "external.c"... see the "XCcallbacktests" function. It makes a variety of callbacks. HTH, Brian This is the MetaCard mailing list.

Re: Markers
First an MC moment. I got a great buzz from making a circumplex using MC. I doubt many out there would be excited by this, but I just can't believe how simple it was once I got to grips with the oval graphic tool. I must confess that I started off wasting time using better known products that just couldn't do the stuff. It works *so* well in MC I feel guilty I still haven't saved enough pennies for the full product. Anyway, This is the tricky bit. The circumplex is divided into octants, much like an eight bit, equi-sliced pie chart. The startangle and arcangle of each slice never change. However, the slices grow outwards to reflect an increasing score and shrink towards the loc of the circle(s) to reflect a decreasing score. (ie. a section of a circle with an increasing or decreasing radius) Now part of this complicated psychological assessment (for that is what it is) is a single point on the circumplex that reflects a summary of the whole personality assessment. The formula is not important, but what I end up with is an angle and vector length. I thought I could use an invisible oval graphic with a size that reflects the vector length, a startangle to represent the angle, and an arcangle of 1. That works. I can get a little dot where I want. However, at the location of that small dot I want to display a marker. After *hours* of tinkering, can I get the marker to do it? Nope. Is this hard to do, or just hard for me to do? Best wishes to all on the list. David Glasgow This is the MetaCard mailing list.

Restrain Answer Dialog?
I'm searching for a solution to make the Answer Dialog stack behave correctly when its style is set to palette. For certain technical reasons, I have a main stack and all its substacks set to palette style, including the Answer Dialog so it will display above the main stack. It appears that the script processing in the main stack ignores the Answer Dialog when the Answer Dialog style is palette. I've tried adding lines to the Answer Dialog scripts to trap the user selection but nothing I've done seems to work (closeStack, mouseUp, etc). Is there any way I can get the Answer Dialog to work "normally" even though it is a palette?

"Steven D'Aprano" [EMAIL PROTECTED] graciously replied: As example calculation would be useful. You didn't state whether the answer actually is an integer. Eg: you want 10.00 but only get 10 with no decimal point. OK, I am taking the standard deviation of a set of 50 numbers. I am trying to recreate the precision of my TI-83 calculator. Under ten-decimal place accuracy I get it. I then set the numberFormat to 0.00 for calculation. The calculations were stored correctly. I then set the numberFormat to 0.##, added 0 to the calculated amounts for display. Again, the displayed amounts were integers. Hashes in the NumberFormat specify that only non-zero trailing figures are kept (eg 2.001000 - 2.001), so again we need to know the actual result of the calculation before we can tell if its a bug. Right: here goes. Calculations with numberFormat set to 0.00 µ = 74.364000 x = 3718.20 x^2 = 279382.46 Sx = 7.6694932382 x = 7.5924109478 n = 50.00 minX = 56.90 Q1 = 68.80 Med = 74.55 Q3 = 79.60 maxX = 88.60 As you can see, everything except for Std deviation and population deviation possess extra zeros. Definitely unneeded and unwanted. But I want the extra digits on Sx and x. So I use the following script to filter out the extra zeros set numberformat to 0.## repeat with i = 1 to 11 put item i of "pmean,psumx,psumxsq,pstddev,ppopdev,pn,pminX,pQ1,pmed,pQ3,pmaxX" into thatprop put line i of the StatSymb of me 0+the thatprop of me into line i of ans end repeat put ans into fld "Stats" Here is the result. µ = 74 x = 3718 x^2 = 279382 Sx = 8 x = 8 n = 50 minX = 57 Q1 = 69 Med = 75 Q3 = 80 maxX = 89 What I want -- and can't seem to get -- is µ = 74.364 x = 3718.2 x^2 = 279382.46 Sx = 7.6694932382 x = 7.5924109478 n = 50 minX = 56.9 Q1 = 68.8 Med = 74.55 Q3 = 79.6 maxX = 88.6 My apologies if you already knew this, but its been my experience that its always good to check the simple things first before firing off bug reports. There's nothing worse than paying for a service call on a television because it wasn't plugged in :-) I agree. Sorry for not being more specific, including calculations, etc. And since I tend to think that a service call may be needed here, I really should have provided more detail. This is a pretty important issue for me. Do you mind if I ask, what are you doing that requires 10 decimal places of accuracy? That's a lot. It is. But it is what I need for this project. Actually the TI-83 stores 14 digits with a 2-digit mantissa. I like the accuracy (after all, I am a math teacher), but again, it is needed if I am to imitate the Ti-83. I notice that for me, numberFormat always ignores the trailing #'s. If I use, set numberFormat to 0.00 the ending four digits are completely ignored, and everything winds up with six decimal places after zero. Of course, I could be doing something completely dumb. But this use of numberFormat works in Hypercard. -- Steven D'Aprano Thanks, Steve. I hope this clears up what is happening. Am I just missing or misusing something? This is the MetaCard mailing list.

Re: Data input: Many fields or just one?
Thanks for the thoughtful comments Steven, On 25/2/2000 10:10 PM, Steven D'Aprano wrote (in part) regarding the choice between using many separate fields for single-value inputs and a single, multi-lined field: 1. Less scripting. Standard behaviour is already built in without any extra scripting. Non-standard behaviour (eg down arrow jumps to the next field) can be accomplished with very little scripting. 2. Data integrity. There is less chance the user can accidently corrupt the data if it is split into seperate fields. Eg there is no way they can accidently overtype all four sets of data in one action, which could happen in a single field. 3. Easier maintainance of the program. Lets say that one of the fields is a person's name. Compare the following data retrievals: get field "Person Name" with: get line 3 of field "Data Entry" In twelve months time when you are maintaining this program, which one is easier to understand? If you decide to move the name field from line 3 to line 2, how many places will you have to edit the script to change 3 to 2? Are you sure you haven't missed one? What if you decide to add an extra field? Now you have to go through the scripts and edit them all again. It is *much* easier to refer to them by name. None of these issues are insurmountable with the single-field data entry method, but it takes extra work to implement it. I'm not sure why you think it is neccessary. _ Gregory Lypny Associate Professor of Finance Concordia University _ "Take chances, make mistakes!" - Ms Frizzle, The Magic School Bus This is the MetaCard mailing list.

Xanim ghost movie
I have a movie playing in a standalone stack for Solaris. It takes a bit of time to load, but the user has the option of going the next section at any time (whether the movie is playing or not). The next section is in a separate stack file. To go to it I use the command: go to card 1 of stack "data/french.mc" in the window of this stack Occasionally, but with no apparent regularity, the movie will decide to start playing on top of the second stack, even though no command there tells it to. This only happens in Solaris, and only when I go to the second stack before the movie has had a chance to load. I am just using a play videoclip looping command in the first stack, and send a play stop videoclip when the user clicks to go to the second stack. Any leads? Thanks much. -Brian This is the MetaCard mailing list. Archives: http://www.mail-archive.com/metacard%40lists.best.com/ Info: http://www.xworlds.com/metacard/mailinglist.htm

There is a brief interval between when you start a movie on UNIX and when you can stop it. This is due to the process creation time, and is not a problem on the other platforms because the movies are played by libraries, not separate processes. About all you can do to work around this is to check to see how long it's been since you started the player. If less than a second or two (depending on the speed of the particular system, unfortunately) then throw in a wait before you stop the player.
