将char *转换为包含特殊字符的BSTR *
|
我正在尝试将ѭ0转换为ѭ1，而我的ѭ0却具有特殊字符，无法进行加密。我尝试了在Web上找到的几种方法，但是回到调用vb代码的过程中，我总是得到不同的结果。我很确定这与特殊字符有关，因为如果我没有特殊字符，那似乎还可以。
我的代码就是这样的东西...
_export myFunction(BSTR *VBtextin, BSTR *VBpassword, BSTR *VBtextout, FPINT encrypt) {
BSTR password = SysAllocString (*VBpassword);
char* myChar;
myChar = (char*) password //is this ok to cast? it seems to remain the same when i print out.
//then I encrypt the myChar in some function...and want to convert back to BSTR
//i\'ve tried a few ways like below, and some other ways i\'ve seen online...to no avail.
_bstr_t temp(myChar);
SysReAllocString(VBtextout, myChar);
没有找到相关结果

。首先进行复制：_export myFunction(BSTR *VBtextin, BSTR *VBpassword, BSTR *VBtextout, FPINT encrypt) { UINT length = SysStringLen(*VBpassword) + 1; char* my_char = new char[length]; HRESULT hr = StringCchCopy(my_char, length, *VBpassword);if (SUCCEEDED(hr)) { // Perform transformations... }另外，请阅读Eric的BSTR语义完整指南。
