How to write in to QVector?

[Engelard]

WINAPI function ReadProcessMemory if succeeds write the result in to users single variable or an array, like this:

char *tempByte = new char[memInfo.RegionSize];
size_t ssss;
ReadProcessMemory(currHandle, (LPVOID)addr, tempByte, memInfo.RegionSize, &ssss);

Dynamic array of my chars is filled with correct data. Why i can't do the same with vectors, why only with default C++ array? Here is analog, it compiles, but crash program when i run it:

QVector<char> tempByte;
tempByte.resize(memInfo.RegionSize);
size_t ssss;
ReadProcessMemory(currHandle, (LPVOID)addr, &tempByte, memInfo.RegionSize, &ssss);

@Engelard Have your tried QVector::data()?

"This function is mostly useful to pass a vector to a function that accepts a plain C++ array."

Small side note, for this cases you normally would use QByteArray rather than QVector<char>

[Engelard]

@VRonin i can't it rejects to compile, i've used byte array from std. Plus, i need to use that data in qSort and qBindariFind, it require array of int values, not raw bytes.

@aha_1980 tnx!

One thing. If you have some data which is an array of bytes or chars or a QByteArray from what you've been saying, and you now say you intend to use that data for sorts/finds "which require ints not bytes", it's strange data that you can treat as bytes or ints. Not impossible, but...?
