i have tried looking around not able find answer this. found explaining when use double asterisk, **, however, not sure whether applied case. i have come across embedded systems code looks bit foreign me : port0 = *(volatile int *)(0x1c002100) what operation doing reads gpio port address 0x1c002100 . deal asterisks ? i have written : port0 = *0x1c002100 are doing type of pointer type casting , hence use 2 asterisks ? best guess. thank ! look @ expression, first convert integer constant pointer, deference pointer, yield integer. same as: int *p = (volatile int *)(0x1c002100); int n = *p; port0 = n; the first * denotes pointer type, second dereference operator. however second line invalid c code, since cannot dereference integer. port0 = *0x1c002100;

i have made in wpf-customcontrollibrary customcontrol, inherits radiobutton. in constructor of customcontrol customradiobutton override dependyproperty ischeckedproperty default value (in case false). /// <summary> /// constructor. /// </summary> static customradiobutton() { defaultstylekeyproperty.overridemetadata(typeof(customradiobutton), new frameworkpropertymetadata(typeof(customradiobutton))); // override default value of base-dependencyproperty. ischeckedproperty.overridemetadata(typeof(customradiobutton), new frameworkpropertymetadata(false)); } as long set in application, use customcontrollibrary, property groupname of radiobuttons, grouping mechanism works. if 1 radiobutton enabled after click, others (which belong same group) disabled. but if don't set property groupname, grouping doesn't work anymore. if click on radiobutton, enabled forever. how can grouping garanteed without explicit setting of property groupname? thank...

i use gcc version 4.6.3. want implement function allocate 2-dimensional matrices , initialize them. used following code, want template based (or generic) one. want generic function handle bool, float, , double @ same time (the procedure similar in cases). please me, or introduce me better way allocate 2d matrix. void doublealloc2d(double ** &t, int r, int c,double initialvalue=0) { t=new double*[r]; if (!t) { if (details) std::printf ("not enough memory.(code: 461546596551)\n"); getchar(); exit(-1); } (int i=0;i<r;i++) { t[i] = new double[c]; if (!t[i]) { if (details) std::printf ("not enough memory.(code: 461651651)\n"); getchar(); exit(-1); } (int j=0;j<c;j++) t[i][j] = initialvalue; } } you don't specify want generic, i'll guess type (and maybe dimensions). usual way create object (inclu...
