I put this code to
tesseract-ocr-API-Example-vs2008.zip<http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-API-Example-vs2008.zip>
:
Pix *image;
char *outText;
char *configs[]={"myconfig"};
int configs_size = 1;
TessBaseAPI *tess = new TessBaseAPI();
if (tess->Init("C:\\tesseract-3.02\\", "deu", OEM_DEFAULT, configs,
configs_size, NULL, NULL, false)) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
image = pixRead("C:\\tesseract-3.02\\phototest.tif");
tess->SetImage(image);
outText = tess->GetUTF8Text();
fprintf(stdout, outText);
and it works for me (VC++ 2008 on Windows XP). I have this
in C:\tesseract-3.02:
C:\tesseract-3.02\phototest.tif
C:\tesseract-3.02\tessdata\deu.traineddata
C:\tesseract-3.02\tessdata\deu.user-words
C:\tesseract-3.02\tessdata\configs\myconfig
And deu.user-words effects results of ocr (I have there words like all,
lazy etc.)
Below are some inline comments.

Windows handle slash correctly (e.g. as directory separator). So problem
should be somewhere else. Are you able to open that path with fopen?

One line per word. Simple txt (utf-8 without BOM, unix EOL - but my test
worked with ANSI encoding and Windows EOL at least notepad++ says so ;-) )

Check if there is set environment settings (echo %TESSDATA_PREFIX%).

Yes it is correct. But if there is problem I prefer to do things step by
step (e.g. you can try set "init only" parameters after init, but it will
not cause error - just they will effect nothing).
