I have another question again. I have created a Matlab Com Dll with matlab's tool "comtool", this dll will read some input files in the current directory and do some computation. I can run the matlab .m file correctly in Matlab. Now I want to call this dll in Visual Basic. I have successfully register the Dll and other things related with the Dll correctly in the visual basic program. When I tried to run the visual basic program, it seems my Dll worked and tried to open those files. But I get an error "can't open file xxxx.txt", where xxxx.txt needs to be opened by the Dll.
I have put those files in the same directory where my DLL located, or my visual basic program located, or c:\windows\system, or c:\windwos\system32. But I still get that error.
Could someone tell me how to solve this problem?
Thanks a lot.
