First-time Windows programming

**Grayson_Peddie** · 06-01-2002

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'.

Where can I find that info of Win32 API out? Any suggestions?

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

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

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

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

Try,

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