    <p>I like figuring things out myself in terms of programming... So I was thinking of a method to loop through multi-dimensional arrays with dynamic dimensions. (mainly for things like brute force)</p> <p>The method I came up with to loop through arrays of unknown dimensions is as follows:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;stdlib.h&gt; /* a simple example of the method I'm using */ void func(int *v,char *usable,int len,int D,int d) { for(v[d] = 0; v[d] &lt; len; v[d]++) { if(d+1 &lt; D) func(v,len,D,d+1); else { for(int i = 0; i &lt; D; i++) printf("%c",usable[v[i]]); printf("\r"); } } } int main() { int *v,z,min = 4,max = 6; for(z = min; z &lt;= max; z++) { v = malloc(sizeof(int)*z); func(v,"0123456789",10,z,0); printf("\n"); free(v); } return 0; } </code></pre> <p>I see this as a nice elegant solution but I've come up with more problems when thinking of multi-threading the process. I would like to know <strong>alternate solutions</strong> for this type of process that I haven't discovered, as well as <strong>possible ways of multi-threading</strong> a process like this. One method I tried was creating pre-determined <em>chunks</em> but because of the large amount of values that need to be processed when digits or usable characters increase are too big, they overflow any normal variables.</p> <p>One might ask: "Why do you need to create a multithreading brute force." And I would reply that the ability to create a multithreaded brute force means the ability to multithread other processes like maze-solving and best-route determination.</p> <p>Thank you in advanced.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
