c# - Can't Modify Dictionary Value -


i've been using code try , modify data written file, no matter do, directly assigning null bytes, won't change. trying access dictionary entry seperate class 1 generated in.

buffer.blockcopy(     pio.getbuffer(),      0,      wat.settingentrylist[0x63e83fff].data,      0,          wat.settingentrylist[0x63e83fff].data.length);  buffer.blockcopy(     pio.getbuffer(),      wat.settingentrylist[0x63e83fff].data.length,      wat.settingentrylist[0x63e83ffe].data,      0,      wat.settingentrylist[0x63e83ffe].data.length);

here variable in class, how initialized dictionary:

public class settingentry {     public byte[] data { get; set; } }

­ public dictionary settingentrylist = new dictionary();

when writing data file, go through each key so:

foreach (keyvaluepair<int, settingentry> se in settingentrylist) {     pio.writebytes(se.value.data); }

i have gone through , debugged. once sure key existed , all, used code, in when ran, application stayed in loop until exited:

while (gpd.settingentrylist[0x63e83fff].data != new byte[gpd.settingentrylist[0x63e83fff].data.length]) gpd.settingentrylist[0x63e83fff].data = new byte[gpd.settingentrylist[0x63e83fff].data.length];

the dictionary not read only.

you writing bytes not dictionary data property inside value in dictionary.

if want override dictionary entry use -

foreach (keyvaluepair<int, settingentry> entry in settingentrylist) {     var val = new settingsentry() { data = new datatype() };     pio.writebytes(val.data);     entry.value = val; }

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
