    First-time Windows programming

    This is my first time programming Windows.

    OK. So I know how to add text to dialog box editor. Right? Well, I've figured out about how I can add another dialog box.

    What I did is, create a test application and named it as Test Dialog. What I did is after I chose MFC appwizard, I follow instructions.

    Then I resize my dialog, move OK button, delete Cancel, name OK as Close, and for that process, I add a new button called a Test.

    Then I add a function after I chose IDC_SENDNAME and BN_CLICKED (I name a Test button of IDC_SENDNAME).

    Then I edit the code:

    Code:
    void CDialogTestDlg::OnSendName()
    {
        // TODO: Add your control handle nodification handle code here
        MessageBox("This is the test.", "Hi!", MB_OK);		
    }
    Well, that's it!

    But... that may sound way to easy to code like that. And, when I visit some of the tutorials you've posted somewhere in the forum, I thought those tutors are hard and just because VC++ are very easy to add controls without adding a single line of code.

    So, for example, unlike cout and cin, I thought there must be a way to copy the text from an edit box and send it to a new dialog box with just a press of a Test button. What I mean is Windows have to take over my text I've entered into, and be able to view text. For example: When I type in "Grayson" in the edit box, and hit "Test", that text string would then be carried over to a dialog box.

    Any suggestions?
    Please keep in mind that I had started to program Windows for the first time.

    If I understand;

    you want to type into one editbox.
    Start a new dialog.
    Have the string you typed in/on the new dialog.

    Look up SetDlgItemText() (or its MFC counterpart)

    I would suggest looking into just the WIN32 API. Understanding the API and how to use it will greatly improve your MFC when you need to do something 'different'.

    static char buffer[256];
    GetDlgItemText(hDlg, nIDDlgItem, buffer, 255);

    then, when the dialog loads put.
    SetDlgItemText(hDlg2, nIDDlgItem, buffer);

    Exclamation Needed detailed information!

    You didn't give me detailed information for what to put the code at...

    Oh... I somewhat forgot something...

    I have IDs and controls that I have in 2 dialogs:

    IDD_OUTPUTTEST_DIALOG : Main dialog

    IDC_QUESTION : Static text (What is your name?)
    IDC_NAME : Edit box {This is where I type in and send a text to a
    new dialog)
    IDC_SENDNAME : This button should copy the text and send them to a new dialog {Button: (Send)}

    IDOK : (Close) Acts as an OK button...

    In MFC ClassWizard:

    ~Begin...~

    Object ID: IDC_NAME
    Messages: EN_CHANGE
    Member Functions: OnChangeName ON_IDC_NAME EN_CHANGE

    (Indicates the display is updated after text changes)

    Object ID: IDC_SENDNAME
    Messages: BN_CLICKED
    Member Functions: OnSendname ON_IDC_SENDNAME BN_CLICKED

    (Indicates the user clicked a {left mouse} button)

    ~End of information in ClassWizard...~

    IDD_OUTPUT_TEXT_DLG : This is a dialog box where I get an output from an edit box I've inputted into a edit box and clicked Send

    IDC_TEXT_PREFIX : (Hi )
    IDC_OUTPUT_NAME : Border turned off; This is where I recieve text that I've typed from edit box in the previous main dialog

    IDOK : Return

    ClassWizard info I've implemented:

    Object IDs: IDC_OUTPUT_NAME
    Messages: EN_UPDATE
    Member Functions: OnUpdateOutputName ON_IDC_OUTPUT_NAME EN_UPDATE

    OK. I put the code in for those 2 files:

    One is for outputtestDlg.cpp, though I included Windows.h...:

    Code:
    void COutputtestDlg::OnChangeName() 
    {
        static char buffer[256];
        GetDlgItemText(IDD_OUTPUTTEST_DIALOG,
                       IDC_NAME,
                       buffer,
                       255);
    }
    
    void COutputtestDlg::OnSendname() 
    {
    }
    Others for outputtextstring.cpp:

    Code:
    void Outputtextstring::OnUpdateOutputName() 
    {
        extern char buffer;
        SetDlgItemText(IDD_OUTPUT_TEXT_DLG,
                       IDC_NAME,
                       buffer
                      );
    }
    Now I got 2 errors here:

    --------------------Configuration: outputtest - Win32 Debug--------------------
    Compiling...
    outputtestDlg.cpp
    C:\Learn\VCPP\outputtest\outputtestDlg.cpp(102) : error C2661: 'GetDlgItemTextA' : no overloaded function takes 4 parameters

    Generating Code...
    Compiling...
    outputtest.cpp

    outputtest.exe - 2 error(s), 0 warning(s)

    I think you are using the C versions not the MFC ones

    Try,

    SetDlgItemText(ID_CTRL, sBuffer);
    GetDlgItemText(ID_CTRL, sBuffer, iSizeOfBuffer);
