Thanhnamdo wroteaccept this value from an other Dialog of an other class
If you want to pass value from one dialog to another you can access the parent dialog's variables by
Then use this pointer to call member functions / change or alter variables of the first (parent) dialog.
Another way is to pass a pointer from one class to another.
Somethings seem HARD to do, until we know how to do them. _AnShUmAn_
Whats application type if you have two dialog you can use
CMain m_Main=(CMain*)GetParent();and in another application you can use m_Main->(your variable)or(your function)and include header from Main class in another class
I'm a beginer. I use Tree Control in Dialog start and I stored Message TVN_SELCHANGED in a value and I want to accept this value from an other Dialog of an other class .But I don't known how to work .

Iam trying to read and write to USB device.
I get an error message
error LNK2001: unresolved external symbol "public: enum FT_STATUS __thiscall CUSBtestDlg::GetStatus(unsigned long *,unsigned long *,unsigned long *)" (?GetStatus@CUSBtestDlg@@QAE?AW4FT_STATUS@@PAK00@Z)
Release/USBtest.exe : fatal error LNK1120: 1 unresolved externals
I tried debugging but in vain.
Can anyone help/ any ideas?
You need to see why the implementation of CUSBtestDlg::GetStatus(unsigned long *,unsigned long *,unsigned long *) is not in any of your cpp or header files that are included in your project. Have you added all the cpp files in your source folder to the project??
have included the ftd2xx.h file as external dependency in the project. so the drivers installed should take care of linking the functions and reading and writing from the device(USB).
I can use their FT_Read and FT_Write functions without any errors.
Infact I have done the same way for GetStatus too.
