Hi all

I got error as below when try to pass second argument in readstring.

code :
while(output.Readstring(Buffer1,100)
{
....
{

Error :

C:\temp\ListFile\ListFile.cpp(112) : error C2664: 'char *__thiscall CStdioFile::ReadString(char *,unsigned int)' : cannot convert parameter 1 from 'class CString' to 'char *'
        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

Hi there,
Using C++ Builder (whatever version >= 5) and of course windows OS:
Drop a TFileListBox in the form visible or not.
Set the Directory to the path of the folder.
There will be a string list contains the paths of every file inside the folder.
Using a TMemoryStream and LoadFromFile() function you are loading the file.
Accessing the Memory property (array of binary data) you can examine the content.
You can use the same TMemoryStream object to clear and load another (or the next) file...
Thats for using C++ Builder.
Similar with Delphi.
I am sure that VC++ has similar ways...
