将char *转换为包含特殊字符的BSTR * [英] converting a char* to BSTR* which contains special characters…

问题描述

你好，

我正在尝试将char *转换为BSTR *，并且char *中的特殊字符不被加密.我尝试了在网络上找到的几种方法，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，因为如果我不输入特殊字符，这似乎还可以....

我的代码符合这些原则...

Hello,

I''m trying to convert a char* to a BSTR*, and my char* has special characters in it from being encrypted. I have tried several approaches found on the web, but back in the calling vb code, I always end up with something different. I''m pretty sure this has to do with the special characters, because if I don''t have them in, it seems to be ok....

my code is something along these lines...

_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);

任何帮助将非常非常感谢！！！
谢谢.

Any help would be very very very much appreciated!!!
Thanks.

推荐答案

不，您不能将BSTR 强制转换为char*.使用ConvertBSTRToString.

No, you cannot cast a BSTR to a char*. Use ConvertBSTRToString.
