Passing Parameters in Visual C++

Hi I am trying to create a Visual C++ porgram, my first one, just trying to get to know it really, I have a form and on that for is a combo box and an edit control and a browse button, could someone help me as I am asking for a in put file from the combo box and the output file from the browse button, ghow would I get the parameters to the ok button where I will do my final piece of coding?

Don't know if code is necessary but here is some anyway:

Code:

---

void CVisTestDlg::OnDropdownCombo1()
{
        CComboBox* getFile = (CComboBox*)GetDlgItem(IDC_COMBO1);

        getFile->ResetContent();

        getFile->Dir(DDL_DRIVES | DDL_READONLY | DDL_EXCLUSIVE, "C:\\*.*");

        // TODO: Add your control notification handler code here       
}

void CVisTestDlg::OnButton1()
{
        CString fileName;
       
        CFileDialog saveas(false, ".zip", "Thingy in a file");

        saveas.DoModal();

        fileName = saveas.GetPathName();
        // TODO: Add your control notification handler code here
       
}

void CVisTestDlg::OnOK()
{
        // TODO: Add extra validation here
       
        CDialog::OnOK();
}

Thanks people.

Ben.

You can simply add member variables to the dialog class to hold the values you need from the other events. This way when OnOK is called you will have access to them.

Cheers Velius, maybe I should change the name of my project to Velius VisTest, so basically make them global? right well i will give it a go and if I can't figure out how to do it I am sure I will be back, again thanks.

Ben.

Not global. Public members. Of course the best way to do it is to make them private and create helper functions to access them.

Cheers Vel8ius, I completely agree about making them private but creating GetFileName() and stuff but this is the first time I have used Visual C++ and its a bit of a nightmare getting used to looking through someone elses code to do your own, I am much happier writing my own classes so i know what functions do what and what relates to what and at least where to put my code, thanks man you have been a great help, it is all working now, just a little more error handling to be done, its only a throw away program to help me learn, and you have certainly done that. Thanks again.

Ben.
