2-dimensional Array in Struct

[Schnuffel]

hello @ all,

i would like to Create a Struct with DllStructCreate an d an 2-dimensional Array in it.

$tagZINT_SYMBOL = "struct;" & _
        "int symbology;" & _
        "int height;" & _
        "int whitespace_width;" & _
        "int border_width;" & _
        "int output_options;" & _
        "char fgcolour[10];" & _
        "char bgcolour[10];" & _
        "char outfile[256];" & _
        "float scale;" & _
        "int option_1;" & _
        "int option_2;" & _
        "int option_3;" & _
        "int show_hrt;" & _
        "int input_mode;" & _
        "byte text[128];" & _
        "int rows;" & _
        "int width;" & _
        "char primary[128];" & _
        "int row_height[178][143];" & _
        "char errtxt[100];" & _
        "char bitmap;" & _
        "int bitmap_width;" & _
        "int bitmap_height;" & _
        "endstruct" ;STRUCT ZINT_SYMBOL / PTR StructCreate
$tZINT_SYMBOL = DllStructCreate($tagZINT_SYMBOL)
ConsoleWrite("Error: " & @error & @CRLF)

My problem is row "int row_height[178][143]". I found 1 Post in the hole forum discussing this point.

The answer from "The Kandie Man" was: "You can't create multidimensional char arrays." --> Link to post

I would like to ask Jos, if it is possible to do something like that. ^^

I attach the original zint.h with the struct reference in "C" the zint.dll and my code. It is a little bit wierd cause there are a few Struct that are referenced with ptr. This part is also not working till now. But one after the other. ^^

In the demo i deleted the ptr in $tagZINT_SYMBOL cause it drops an error too.

here is the origin end of $tagZINT_SYMBOL
"BYTE bitmap_height;" & _
 "ptr* "& $ptrZINT_RENDER & " *rendered;" & _ ; this one is the second problem ^^
 "endstruct" ;STRUCT ZINT_SYMBOL / PTR StructCreate"

zint.h = 0 bytes

int row_height[178]; /* Largest symbol is 177x177 QR Code */

https://zint.org.uk/manual/chapter/5

row_height = array of integers     Representation of the height of a row.     (output only)   I would think this means that row_height is an array of 178 elements, where each element ranges between 0 and 177 in value.   Edit: The structure in the above linked zint.h file looks different than yours:     unsigned char encoded_data[178][143];     int row_height[178]; /* Largest symbol is 177x177 QR Code * Googling unsigned char encoded_data leads to this: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/f29fbf40-094f-4ece-933d-4f161923ebfa/problem-using-a-struct-as-parameter-for-bidirectional-data-transfer-c-c-interop?forum=csharplanguage [MarshalAs(UnmanagedType.ByValArray, ArraySubType = UnmanagedType.U1, SizeConst=25454)]   So it seems like encoded_data might be represented by byte encoded_data[25454]
