One of the major issues with NIReport is that it does not save the information to a file. A way around this issue is to print the report using NIReport_Print and point to the Adobe PDF printer that is installed with Adobe Acrobat.
Printing to the Adobe PDF opens a "File Save" dialog box where you can enter the filename. This works unless your are trying to do automated tests and don't want the operator to have to create a new name each time.
Below is a code segment for automating the "File Save" by creating a key in the registry. The report is created using the normal NIReport functions.
/* create test application name, must have path information */
sprintf(caTestApplicationWithPathInfo, "%s\\myapplicationname.exe", TEST_DIRECTORY);
/* create filename with path information from serial number, date and time */
sprintf(caFilenameWithPathInfo, "%s\\%s_%s_%s.pdf", TEST_DIRECTORY, caSerialNumber, caDate, caTime);
/* create a key in the Current User using the application and filename. */
/* this key is created each time and is destroy by Adobe PDF printer when it prints */
RegWriteString(REGKEY_HKCU, "Software\\Adobe\\Acrobat Distiller\\PrinterJobControl", caTestApplicationWithPathInfo, caFilenameWithPathInfo);
/* now print the report */
NIReport_Print(iReportHandle, "adobe pdf", 1);
This creates a file in the test directory without the operator entering any data.
Two gotchas:
1. The directory TEST_DIRECTORY must already exist and the user must have read/write access.
2. The pdf file can not exist, an error occurs if you try to overwrite an existing file.
