Replacing Wchar_t

Question

How can I replace string in a wchar_t variable?

wchar_t text[] = L"Start Notepad.exe";

I want to replace Notepad.exe with Word.exe .

Answer 1

wchar_t is just one character, not the string. In your case you need std::wstring, string consisting of wchar_t. Here is answer on how to replace one substring with another .

Answer 2

Basically you need to use a pointer or index variable and replace the characters one by one and end with the null character.

Here is an example, (note that C++ programmers might hate this code, but is fairly acceptable for C programmers...):

wchar_t lpSrcText[] = L"Start Notepad.exe";
wchar_t const * lpReplace = L"Word.exe";

int i = 0;
while(*(lpReplace + i))
{
     lpSrcText[6 + i] = *(lpReplace + i);
     i++;
}
*(lpReplace + i) = L'\0';
