Not RTDLL. My purpose is to read a csv file and find a value . Then I write the index of this value to S7 memory.(MW500) But the read csv function doesn't work and the write value to S7 memory works in the DLL. I also identify my source code of read csv function. I create a Win32 console application (*.exe) and put the same code of read csv function. The application can work. So, I don't know why the DLL can't work but the application can work. ps:(a).My test platform: WinAC RTX v4.4.1 in a Panel PC 677. (b).The attached files: One is the CCX program created by ODK4.2. The other is my identified Win32 application of read csv function. C1.csv is the test file. Tks. Angus. Attachment 0811CCX.zip (434 Downloads)

The other question: My return of SFB65001 is right.(ex:0x0001,0x0002....) Angus. Attachment ODK_CCX.JPG (359 Downloads)

	Last edited by: TomDeWou at: 8/12/2009 9:21 AM Angus, did you take the screenshot from the document available in the online FAQ for WinAC ODK? Because this one is obviously different from the installed one. Have Fun! TomDeWou

Orignal method : ifstream Now method : fstream Then the DLL can work. But I don't know why "ifstream"in the DLL can't work. Because Icreate a Win32 console program using ifstream and it can work.
