Copy a CString to a Stream*

Alexandru Savescu

Hi! I am using an application that is using both managed to unmanaged code. I want to copy data from a CString to a Stream* (it may be MemoryStream or BufferedStream - whichever is faster). Can anyone help? Thanks Best regards, Alexandru Savescu

Convert the CString to a String* and then pass the String* to the Stream* Nish

Sorry Nish, it does not work. Here is what I did:

CString str = "aaaa":
String\* str1 = new String (str);
MemoryStream\* mem1 = new MemoryStream (str1, false);

and the result is:

c:\Work\Test.cpp(332): error C2664: 'System::IO::MemoryStream::MemoryStream(unsigned char __gc[],bool)' : cannot convert parameter 1 from 'System::String __gc *' to 'unsigned char __gc[]'

I found an work arround that compiles and works but I hate it:

MemoryStream* mem = new MemoryStream (n) ;// specify the size
for (int i = 0; i < n; i++)
mem->WriteByte (str[i]);

Do you have another solution? Thanks! Best regards, Alexandru Savescu

Try this:

CString str = "aaaa";
String* strText = new String (str);
Byte message[] = System::Text::Encoding::ASCII->GetBytes( strText );
MemoryStream* sStream = new MemoryStream( message );

If you want to use diffrent encoding replace the bold text with the appropriate encoding like: Unicode, UTF7 or UTF8. I should work :)
