Question about backgrounds
Okay I am a newbie to Revolution. I have used Hypercard for decades and find the Revolution view of backgrounds and groups a bit confusing. In Hypercard I was used to being able to manipulate backgrounds at will and have it applied to all other cards automatically. In Revolution I find that if I modify the background on one card then the other cards with the same background lose the background (and all data therein) altogether. I have looked through the help and tutorials with little insight on how to accomplish this. Is there a way to manipulate the background, or more specifically a group on a background, on one card and have it automatically applied to the other cards without having to re-create the other cards? Any insights? Nate ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
Relative paths for external audio and video files?
Dear Jerry, I was just about to post this exact question myself, so I would be grateful if you could let me know of any solution you find on this! I've used Import as Control myself, but you're right - it's not ideal for larger files and in any case it doesn't seem to transport across platforms, which is what I want to do (I'm developing on a mac but want to burn on cd to use on windows). Robin I am a new user of Revolution. I noticed that both Videos and Images are not embedded and need to connect with external files. This is easy when I'm building, the images and videos are right there on my hard drive. But when I build to CD I need relative paths so that the images and videos I burned to disc will play in anyones CD drive regardless of the Drive letter. How do you create/insert relative paths in Revolution? I am resending this for publication in full on the list. I was advised by a kind gentleman on the users mail list that Import as Control would work. Well, Yes and No. I was able to import as control images, text and snapshot but not video or audio files. Is there a secret to this? Video files work great from the toolbar. Then there is the question of whether you would want embedded video files sized 387mb as anything but external files. I am running Rev version 1.1.1 on a PC running Windows 98SE.

Re: Question about backgrounds
Nate, I also started with HyperCard. I also found the differences between Rev and HC to be an annoyance until I got more accustomed to the differences. Rev is definitely more powerful and versatile. The easiest way to simulate HC backgrounds is to start with a clean new stack. Build all of the controls and fields that should appear on all cards. Select all, and group those items. Look at the properties of the group and look at the last tab labeled Group. Make sure Background Behavior is checked. If it is not, this group only lives on the current card. And this is the key to working in a simulated HC world... Always select the group and Edit the group when you need to add objects to your background. This way they automatically appear on all of the cards. ~Roger Eller [EMAIL PROTECTED] - - - - - - Nate [EMAIL PROTECTED] Recently Wrote: Okay I am a newbie to Revolution.

determining array lengths
After looking around in the documentation, I haven't been able to find a simple function to determine the number of keys for a given array dimension. Do I need to parse the output of the keys function for this, or have I overlooked something in the documentation? I was hoping the number function might do it, as in the number of keys in myArray The expected output would be something like [100,50], to indicate the dimensions of the array. The number of lines in the keys of myArray only works for one-dimensional arrays. Thanks... ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
Re: determining array lengths
Hi Brad, I looked into this a while ago. My solution was: 1) If the second dimension is fixed (always NN elements), you can suffice by saying: put (the number of lines of the keys of tArray / NN) 2) If however NN is variable, you can get it with the following trick: put the keys of tArray into tKeys split tKeys using return and comma put the number of lines of the keys of tKeys I know it looks convoluted, but it works, even if the second dimension varies.

Re: matrixMultiply
Hi Brad, If I remember correctly from my Linear Algebra classes, in order to multiply two arrays, their dimensions have to be such that the first dimension of the second array equals the second dimension of the first array, so they should be of the sort: Array1 [m x n] and Array2 [n x p] which means that, in this case, as it's not a square array, it can't multiply it with itself. Try again wih a square array. Hope this helped, Jan Schenkel. As we grow older, we grow both wiser and more foolish at the same time.

I had misunderstood the wording of this function in the Transcript dictionary. The part that threw me off was this part of the at the end of the entry under Extents: Each line contains two numbers separated by commas. The first item is the smallest number of an element in that dimension, and the second item is the largest number. Is this misleading, or am I just misunderstanding this text? My reading of this is that Extents provides the lowest and highest values in the Elements of an array (sort of like the min and max functions), not the index keys. But in reality, as I'm glad to learn, the Extents function provides the lowest and highest values of the index keys in an array dimension. ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Another question about matrixMultiply in Rev: According to the entry in the Transcript dictionary for the operator *, we should be able to multiply matrices by using the * operator instead of the matrixMultiply() function. I'm trying it with a 4 x 4 array, so it should work, but using the * operator yields different results from matrix multiply. Here's the example I'm using. The following text is read into a 4 x 4 array variable with numeric keys, named outputArray 1 0 1 1 1 1 0 0 1 0 1 0 0 1 1 0 Next, I want to multiply this array by itself: put outputArray * outputArray into productArray or put matrixMultiply(outputArray,outputArray) into productArray The first example, using * yields an incorrect answer: 1 0 1 1 1 1 0 0 1 0 1 0 0 1 1 0 The second, using matrixMultiply yields the correct answer: 2 1 3 1 2 1 1 1 2 0 2 1 2 1 1 0 So, why didn't the * operator produce the correct answer? It did work, for the simpler case of multiplying a number times a matrix, but not for a matrix times a matrix. ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

However, the number of rows in the firstArray and secondArray need not be the same. For example, you can multiply these two arrays: 1 0 3 4 5 2 4 9 9 3 6 9 because one is 3x2 and the other is 2x3.
