i have created vc++ dll in visual studio 2013. extern "c" int __declspec(dllexport) __cdecl convertimagetotext(char* datapath, char* imagefilepath, char* captchacode) { // return 0; } i'm using in borland c++ builder 6 that. hmodule dllhandle = loadlibrary("captcha.dll"); int (__cdecl *convertimagetotext)(char*,char*,char*); convertimagetotext =(int (__cdecl *)(char*,char*,char*))getprocaddress(dllhandle, "convertimagetotext"); if (convertimagetotext != null ) { convertimagetotext("","",""); }else { showmessage("convertimagetotext pointer not found !"); } it's working in win7/8/8.1.there isn't problem. but can't find pointer of convertimagetotext on windows xp sp3. i have changed vc++ dll project "platform toolset" "visual studio 2013 - windows xp (v120_xp)".nothing not changed. i have checked visual c++ redistributable packages.all i...

int main() { int a[4][2] = {1,2,3,4,5,6,7,8}; printf("%d\n",*(a[2]+1)); printf("%d\n", *(*(a + 2)+1)); getch(); } two-dimensional array can thought of one-dimensional array. output of program 6 in both printf. question how printf("%d\n", *(*(a + 2)+1)); executing , how precedence of asterik * , + evaluating. let's consider both printf calls. a[2] in cell int[2] = {5,6} a[2] + 1 pointer holds address of number 6 (a[2] implicitly converted pointer), after dereference 6. a , int[4][2] array, converted pointer (after conversion holds pointer first element) a + 2 pointer holds address of pointer number 5 *(a + 2) pointer holds address of number 5 *(a + 2) + 1 pointer holds address of number 6 *(*(a + 2) + 1) number 6 edit: sorry, wrong statements. take account comments , need add in above example lvalue expression of array type implicitly converted pointer first element.

i try onselectionchange event ckeditor. when select ckeditor rise correctly event, if select else in same paragraph event not raised. is there way make creditor rise onselectionchange event time select text. ? any advice on solve issue ? thanks the answer in api documentation : fired when selection inside editor has been changed. note event fired when selection's start element (container of selecion start) changes, not on every possible selection change. selectionchange fired less frequently, on every context (the elements path holding selection's start) change. you can observe mouse , keyboard actions though ( jsfiddle ): function logselection() { console.log( this.getselection() ); } ckeditor.replace( 'editor', { on: { contentdom: function() { this.document.on( 'mouseup', logselection, ); this.document.on( 'keyup', logselection, ); } } } );
