PureBasic Forums - English

anyone has a successful example of passing memory pointers across programs in purebasic (like runprogram X and the output of X is a memory pointer which the parent can access??)

See ReadProcessMemory on MSDN. PureBasic supports this function natively as "ReadProcessMemory_" (note the underscore).

the X program execution is already over and it actually computes a huge array result, I need to pass back this huge array to the caller program, but will readprocessmemory_ still be around if the program execution is over?

All memory for your application is freed once the program ends. I'm sure ReadProcessMemory will fail if you attempt to call it.

You could consider using shared memory.

well there are 2 things here
1. i generate the source of the child file from the parent file
2. the array is defined along with its values which i dump into the child filed
3. similar to your esgrid, i simply write back the values/formulas given in a grid back to the child file (so X43 is already given a formula back in the child file as X43=X41+X32)
4. I then run the child file and it dumps back the actual values in the grid
5. i print the grid in the parent file
6. for every sheet/grid i make, i generate a new child file and wait for it's output which update's back the parent

so for example in a cell I should be able to type a purebasic formula/code snippet and the child file should throw back the values and the parent should print it back.
One option is back to back unix sockets. but i need it to "actually run those formulas", so rather than write my own interpreter i decided to poach back on PB itself
So I have
Parent-->has a Dim(x,y), inputs at parent-->generate child code-->child code executes and throws back values to parent-->parent simply displays the grid...
hope that helps clarify my point

the other option is dont DIM,
simply change the view on top with the scroll bar below
for example the rows and column "numbers" are fixed gadgets/text gadgets
when you move the scrollbar gadget/click on it, it increments by 1 cell size as it increments in windows )
