I was wondering how I can convert a string (Loaded from the config). Convert into a Location object. I've already tried this code:
private Location StringToLocation(String input, Main plugin) {
Location world = new Location(Bukkit.getWorld(plugin.getConfig().getString("world")), 0, 0, 0);
int index;
int LengteString;
String[] myCoordinaat = { "", "", "" };
for (int iLoop = 0; iLoop < 2; iLoop++)
{
index = input.indexOf(",");
LengteString = input.length() - index;
myCoordinaat[iLoop] = input.substring(index, LengteString);
input = input.substring(0, index + 1);
}
myCoordinaat[2]=input;
Bukkit.getLogger().info("x: " + myCoordinaat[0] + " y:" + myCoordinaat[1] + " z:" + myCoordinaat[2]);
world.setX(Double.parseDouble(myCoordinaat[0]));
world.setY(Double.parseDouble(myCoordinaat[1]));
world.setZ(Double.parseDouble(myCoordinaat[2]));
return world;
}
Thanks in advance!
There is a very easy solution to your problem that doesn't even involve you parsing the location yourself.
//Save location
getConfig().set("path.to.location", loc);
saveConfig();
//Load location
Location location = (Location) getConfig().get("path.to.location");
You can basically store the object in the config and then restore it. Just keep in mind that the world needs to be loaded for the Location to be parsed.

I recently build an masonry gallery with html and css. I used the display: grid; property to make it look like so. Now I am trying to create randomized layouts. Therefor I want to create elements with classes. I want to append / elements to the elements, store those elements inside an array and later append them inside my "masonry" . I put in different console.logs to see whats happening, but I get some either weird or undefined returns. Javascript can be as tricky as it can be fun for beginners, so I hope you guys can help me out.
Thank you all. :)
//arrays and variables
const figures = [];
let newFigures = "";
const divs = [];
let newDivs = "";
function makeCells(){
for(let i = 0; i < 33; i++){
newFigure = document.createElement("figure");
figures[i] = newFigure.classList.add("cell", "cell--" + i);
newDiv = document.createElement("div");
divs[i] = newDiv.setAttribute("id", i);
console.log("log1: " + newFigure.classList);
console.log("log2: " + figures[i]);
}
console.log("log3: " + divs);
console.log("log4: " + figures);
console.log("log5: " + divs);
for(let i=0; i<3; i++){
figures[i] = newFigure.appendChild(newDiv);
}
console.log("figures = " + figures);
console.log("divs = " + divs);
let z = {};
for(let i=0; i<3; i++){
z = figures[i];
document.getElementById("masonry").appendChild(z);
}
console.log(document.getElementById("masonry"));
}
Here is a picture of the corresponding console.logs.

This works as intended:
const figures = [];
let newFigure = "";
const divs = [];
let newDiv = "";
function makeCells(){
for(let i = 0; i < 33; i++){
newFigure = document.createElement("figure");
newDiv = document.createElement("div");
newFigure.appendChild(newDiv);
document.getElementById("masonry").appendChild(newFigure);
figures[i] = newFigure.classList.add("cell", "cell--" + i);
}
console.log(document.getElementById("masonry"));
}
Sorry to bother you guys.
I don't like this line of code, mainly because the add() method does not have a return value.
figures[i] = newFigure.classList.add("cell", "cell--" + i);
I would split it into two statements.
newFigure.classList.add("cell", "cell--" + i);
figures.push(newFigure);
I've been following this tutorial for SSL/TLS online (well its more of reading the guys source code and following along) but I've hit a bumpy road with this EncryptMessage part because it pushes the data out of the way and encrypts the wrong info.
The pbloBuffer that I send it is:
GET / HTTP/1.1\r\n
HOST: www.google.com\r\n\r\n
But when I do pbMessage = pbloBuffer + Sizes.cbHeader; I end up with (even the microsoft websites says to do this)
1\r\n
HOST: www.google.com\r\n\r\n
Now pbMessage is the code above, and that's inserted under SECBUFFER_DATA so it's not even getting the full data. From what I understand SECBUFFER_DATA is the "user" data that the Webserver will decode and process.
Can you find out how to fix this and properly send the encrypted data?
Full source: (This code is experimental as I am trying to understand it before I makes changes)
int Adaptify::EncryptSend(PBYTE pbloBuffer, int Size) {
SECURITY_STATUS scRet{ 0 };
SecBufferDesc Message{ 0 };
SecBuffer Buffers[4]{ 0 };
DWORD cbMessage = 0, cbData = 0;
PBYTE pbMessage = nullptr;
SecPkgContext_StreamSizes Sizes = { 0 };
QueryContextAttributesW(&hContext, SECPKG_ATTR_STREAM_SIZES, &Sizes);
pbMessage = pbloBuffer + Sizes.cbHeader;
cbMessage = (DWORD)strlen((const char*)pbMessage);
Buffers[0].BufferType = SECBUFFER_STREAM_HEADER;
Buffers[0].cbBuffer = Sizes.cbHeader;
Buffers[0].pvBuffer = pbloBuffer;
Buffers[1].BufferType = SECBUFFER_DATA;
Buffers[1].pvBuffer = pbMessage;
Buffers[1].cbBuffer = cbMessage;
Buffers[2].BufferType = SECBUFFER_STREAM_TRAILER;
Buffers[2].cbBuffer = Sizes.cbTrailer;
Buffers[2].pvBuffer = pbMessage + cbMessage;
Buffers[3].BufferType = SECBUFFER_EMPTY;
Buffers[3].cbBuffer = SECBUFFER_EMPTY;
Buffers[3].pvBuffer = SECBUFFER_EMPTY;
Message.cBuffers = 4;
Message.pBuffers = Buffers;
Message.ulVersion = SECBUFFER_VERSION;
scRet = EncryptMessage(&hContext, 0, &Message, 0);
if (send(hSocket, (const char*)pbloBuffer, Buffers[0].cbBuffer + Buffers[1].cbBuffer + Buffers[2].cbBuffer, 0) < 0) {
MessageBox(0, L"Send error", 0, 0);
}
return 0;
}
first - you need call QueryContextAttributesW only once after InitializeSecurityContextW return SEC_E_OK - no sense call it every time, when you need send data. and save result. say inherit your class from SecPkgContext_StreamSizes - class Adaptify : SecPkgContext_StreamSizes; and call on end handshake (once) QueryContextAttributesW(&hContext, SECPKG_ATTR_STREAM_SIZES, this);
about send send data - in your case Buffers[1].pvBuffer of course must point to your actual data pbloBuffer but not to pbloBuffer + Sizes.cbHeader code can be like this:
int Adaptify::EncryptSend(PBYTE pbloBuffer, int Size) {
SECURITY_STATUS ss = SEC_E_INSUFFICIENT_MEMORY;
if (PBYTE Buffer = new BYTE[cbHeader + Size + cbTrailer]) {
memcpy(Buffer + cbHeader, pbloBuffer, Size);
SecBuffer sb[4] = {
{ cbHeader, SECBUFFER_STREAM_HEADER, Buffer},
{ Size, SECBUFFER_DATA, Buffer + cbHeader},
{ cbTrailer, SECBUFFER_STREAM_TRAILER, Buffer + cbHeader + Size},
};
SecBufferDesc sbd = {
SECBUFFER_VERSION, 4, sb
};
if (SEC_E_OK == (ss = ::EncryptMessage(this, 0, &sbd, 0)))) {
if (SOCKET_ERROR == send(hSocket, (const char*)Buffer, sb[0].cbBuffer+sb[1].cbBuffer+sb[2].cbBuffer+sb[3].cbBuffer, 0))
ss = WSAGetLastError();
}
delete [] Buffer;
}
return ss;
}
so you need allocate new buffer with cbHeader + Size + cbTrailer size (wher Size is your actual message Size and copy your message at Buffer + cbHeader
I want to get the details of the unread missed calls list in my android app.
I came up with this code but this shows the whole list of my missed calls not only those which are unread.
lv= (ListView)findViewById(R.id.listView1);
List<String> lst=new ArrayList<String>();
String miss_read="read";
String unread_condition=miss_read+"=0";
String[] projection = {CallLog.Calls.NUMBER,CallLog.Calls.CACHED_NAME,CallLog.Calls.TYPE};
//String[] projection = {Integer.parseInt(CallLog.Calls.MISSED_TYPE};
//String where = (CallLog.Calls.TYPE+CallLog.Calls.NEW+"="+CallLog.Calls.MISSED_TYPE);
String where = (CallLog.Calls.NEW+" = "+"new"+" AND "+CallLog.Calls.TYPE+" = "+CallLog.Calls.MISSED_TYPE);
Cursor c = this.getContentResolver().query(CallLog.Calls.CONTENT_URI,projection,where, null, null);
int i=0;
if(c.moveToFirst())
{
do
{
if(CallLog.Calls.IS_READ!="is_read")
lst.add(c.getString(0)+"not read");
//i++;
}while(c.moveToNext());
}
ArrayAdapter<String> adpt=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,lst);
lv.setAdapter(adpt);
does anybody provide me the solution for my problem...??
Try this.
String[] projection = new String[] { CallLog.Calls.NUMBER,
CallLog.Calls.TYPE, CallLog.Calls.NEW };
String where = (CallLog.Calls.NEW + " = " + "1" + " AND "
+ CallLog.Calls.TYPE + " = " + CallLog.Calls.MISSED_TYPE);
Cursor c = context.getContentResolver().query(CallLog.Calls.CONTENT_URI,
projection, where, null, null);
Is there a way in Visual Studio 2005 to find out which pointer or variable is causing this access violation? I tried to run in debug mode and break when it happens. By looking at the call stacks, it happens in the end of the function (see below). Could using try/catch be able to find out which pointer it is?
EDIT:
Posting my code:
There is a Qt line edit and a checkbox in my application. Toggling the checkbox would switch the data format in the line edit. Like 3'b111 <==> 3'h7. Below is the callback function that is connected to the checkbox stateChanged signal. The exception happens in the end of function, when destructing local variables.
// switch hex/binary format. 15'h0000 <==> 15'b000000000000000
void switchDataFormat(int checkState) {
QLineEdit* writeRegLE = this->getWriteRegLineEdit();
string oldText = writeRegLE->text().toStdString();
string newText = "";
int maxLength;
string regLengthText = oldText.substr(0, oldText.find('\''));
string regValueText = oldText.substr(oldText.find('\'')+2);
int regLength = this->getRegLength();
if (checkState == Qt::Unchecked) {
// switch to binary format
maxLength = regLengthText.size() + 2 + regLength;
string binaryText;
for (int i = 0; i < regValueText.size(); ++i) {
binaryText += hexToBinary(regValueText[i]);
}
newText = regLengthText + "'b" + binaryText.substr(binaryText.size()-regLength); // trimming leading zeros to fit regLength
}
else {
// switch to hex format
maxLength = regLengthText.size() + 2 + regLength/4 + 1;
newText = regLengthText + "'h";
// zero filling to 4*n bits
if (regLength%4 != 0) regValueText = string(regLength%4,'0') + regValueText;
for (int i = 0; i < regValueText.size(); i+=4) {
newText += binaryToHex(regValueText.substr(i,4));
}
}
writeRegLE->setMaxLength(maxLength);
writeRegLE->setText(QString::fromUtf8(newText.c_str()));
}
Id like to have linked string in my ncurses menu to something like:
/bin
/hello
/home
...
And i have vector of components named w_files which have variable name (bin, hello, home, ...) and when i do this:
chdir(w_actDir.c_str());
this->selected = 0;
unsigned int n_choices = w_files.size();
my_items = (ITEM **)calloc(n_choices+1, sizeof(ITEM *));
for(unsigned int i = 0; i < n_choices; ++i){
string toShow = w_files[i]->getName();
my_items[i] = new_item(toShow.c_str(), "");
}
my_menu = new_menu((ITEM**)my_items);
set_menu_mark(my_menu, "");
set_menu_win(my_menu, this->w_window);
set_menu_format(my_menu, LINES-5, 1);
int center = COLS/2;
set_menu_sub(my_menu, derwin(this->w_window, LINES-5, center-5, 3, 1));
post_menu(my_menu);
wrefresh(this->w_window);
its ok, result looks:
bin
hello
home
...
But when change line string toShow = w_files[i]->getName(); to string toShow = "/" + w_files[i]->getName();
Result is:
Can anybody help me, please?
Thank you.
Actually, after posting the comment I had an idea for an answer - the safest way would be appending to toShow string.
Code sample:
string toShow = "/";
toShow.append(w_files[i]->getName());
