So ColdFusion need to read the file and pass the bytes[].
once i read file using <cffile action="read"> then how to convert content to base64? i know there is function toBase64 but this takes string or binary data only.

I have tried to create an array dynamically , write it to a file and at last try to display all data from file but while running it accept the data but it stop working while displaying all data from file.how can we dynamically create an string array , write it to a some data file like "test.txt" and at last display all that data from file "test.txt" in c++? please help.
How I can to read any gdsii file in python,or Convert gds file into text format using gds2text script?
If you can use a C/C++ compiler you might consider using gds2gdt and gdt2gds to read and/or write GDSII using any language/shell of your choice. GDSII is a stream of records each of which is represented in a single line of compact GDT format text. For instance:
p{10 w1.2 xy(41.2 17.1 41.2 33.9)}
is a two-point path on layer 10 with a width of 1.2. you can run these programs externally or call them within your program similar to reading/writing a text file.

I am trying to extract a (UTF-8) text file from a zip file:
TZipFile *zFile = new TZipFile;
zFile->Open(L"C:\\test.zip", zmRead);
TByteDynArray bda;
zFile->Read(L"test.txt", bda);
zFile->Close();
ShowMessage(WideStringOf(bda));
This doesn't work. I get a string, but with weird content.
If I use zFile->Extract() it works fine, but I don't want to use the disk (performance).
Is there a way to use the read function on a UTF-8 file?
The problem is not with TZipFile itself, the real problem is actually with WideStringOf() instead.
TZipFile::Read() returns the raw bytes of the specified archived file (decompressing if needed), so your bda variable is a UTF-8 encoded byte array. However, WideStringOf() expects a byte array that is encoded as UTF-16LE instead. That is why you are seeing incorrect results.
To decode the byte array as UTF-8, use this instead:
ShowMessage(TEncoding::UTF8->GetString(bda));
Hi I have an image in my memory and I want to sent it through an external FTP library.
This FTP library accepts only and only standard C FILE and the sample codes provided by this library reads data only from hard disk. In my application I don't want to store my images in the hard disk and then read them using FILE variable, instead I want to do the conversion in my memory so it's faster and more professional.
My image is in the form of uchar * but I can change it to std::String or QByteArray or any other type of string. Now I want to know how can I have a file which is filled by my image data so I will get rid of storing it into the hard disk and read it again.
My pseudo code:
uchar * image = readImage();
FILE * New_Image = String2FileConverter(image); //I need this function
FTP_Upload(New_Image);
On Posix systems, you can use fmemopen to create a memory-backed file handle.
How do i correctly read and write file with text in cp866 encoding in C++?
UPD: i found a way to write to a file
wofstream rstrm(fileName);
rstrm.imbue(locale("rus_rus.866"));
rstrm << text_in_cyrillic.c_str();
rstrm.close();
Now how can i read file in similar way? I need to read file content to tstring object.
Use WideCharToMultiByte and tell it cp866, and write the results.
