Summary:
Most commands in Citect that create files will fail if the specified folder does not exist. How do you create folders from Cicode?
 

Solution:
It is possible to execute the DOS MD (make directory) command using the Cicode Exec() function (Q1028, Q2138). However, the Windows API offers a DLL function that will do this without opening a DOS window. It also has the advantage that it will create multiple nested folders if necessary. For example, with the CreatePath code below, the following command will create a Reports, Daily, Section 1, and Processing folder if they do not already exist: 
CreatePath("c:\Reports\Daily\Section 1\Processing");

Use the following code in CitectSCADA 6.10 and later. In earlier versions of Citect, replace the DLLCallEx() function with DLLCall(). The MakeSureDirectoryPathExists function is not available on Windows 95/98/NT.

INT mhCreatePath = -1;

// Creates all folders necessary for the specified path to be valid

// If the path includes a filename, the filename is ignored.

// Path substitution may be used.

//

// Returns TRUE if successful

//

INT

FUNCTION

CreatePath(STRING sPath)

	sPath = PathToStr(sPath);

	IF mhCreatePath = -1 THEN

		mhCreatePath = DLLOpen("dbghelp.dll", "MakeSureDirectoryPathExists", "AC");

	END

	RETURN DLLCallEx(mhCreatePath, sPath);

END
