sx ted,

I've updated the program. Now it includes these functions:

int gFileOpen(string file_name,int mode);
bool gFileWrite(int handle,string data);
bool gFileClose(int handle);
string gFileRead(int handle,int length=0);
void gFileSeek(int handle,int offset, int mode);
bool gFileDelete(string file_name);
int gFileSize(int handle);
int gFileTell(int handle);
bool gFileFlush(int handle);
bool gFileCopy(string source,string distance,bool IfExists);
bool gFileMove(string source,string distance);

I hope you enjoy it.

Hi guys,
I see you by your words you're very good with these things
and I hope you can give me a hand with my dll import problem.
I did exactly as codersguru explained with the filehandler dll.
I have the .ex4 file in the indicators directory. In the .ex4 there's an include to a file(.mqh) in the include directory which has an #import statement within to a dll in the libraries directory.
Dll is loaded but as soon as i drag the indicator in the chart I read in the expert tab of strategy builder: cannot call function functionname from dll ' dllname.dll'
I tested the dll from an .exe and all the function are running but within the .ex4 i can't find a way.I'm sure I'm missing something but I really don't know what. what could it be?
Thank you

gnrslash,

If you enbabled "Allow DLL Import" option and still getting the message "cannot call function functionname from dll dllname.dll" it means there's something wrong in dll code.

Could I see the source code of the dll?

gnrslash,

The problem is Visual basic dosen't create a standard dll.

Please review this article:
http://www.vb-helper.com/howto_make_standard_dll.html

I've made the dll for you and I'll send it to your email now (I didn't test it yet in MQL4, please test it and tell me the result).

I'd have bet something like this.
anyway, I didn't receive your email. I guess mail server blocks that kind of attachment. try to zip and resend. thank you again

Check your mail, if have not got them could I upload the dll and the visual basic calling example here?
