Thanks to "toxcct" and "cedric moonen" Ive learned how to Link my CDialog's together, Thank you both!
<br />
#include Button01Dlg.h<br />
<br />
void CClientDlg::OnButton01() <br />
{<br />
CButton01Dlg dlg;<br />
dlg.DoModal();<br />
}<br />
But Ive come to Notice that only Text can be added to the CButton01Dlg on interface... I was wondering if there was a way to somehow get printf or cout working in Button01Dlg.cpp in order to apply variables?...
Thanks for any Help you guys seem to be the best forum ive found yet!

You could use sprintf() to write to a character string which could be displayed in a CStatic or CEdit control.

Would it Go under;
<br />
CButton01Dlg::CButton01Dlg(CWnd* pParent )<br />
: CDialog(CButton01Dlg::IDD, pParent)<br />
{<br />
<br />
}<br />
or
<br />
void CButton01Dlg::DoDataExchange(CDataExchange* pDX)<br />
{<br />
CDialog::DoDataExchange(pDX);<br />
}<br />
or
<br />
BEGIN_MESSAGE_MAP(CButton01Dlg, CDialog)<br />
END_MESSAGE_MAP()<br />
Sorry im kinda new at Interface programs... ive only made databases and so forth jus dos based... But those are the only 3 sections under Button01Dlg.cpp where would i enter it and would it look like;
<br />
sprintf("%s %s you are %s years of age\n", First, Lastname, Age)<br />
<br />

What I meant was, you could use sprintf() (which works exactly like printf() but writes to a string vs. standard output) to display values of variables which could be shown by a static text control (i.e. CStatic) or an edit control (CEdit). The latter is preferred, since it supports scrolling, which can come in handy when displaying large amounts of text.
The actual display would typically occur within a button handler. For example:
CMyDialog::OnBtnFooClicked()
{
char szResult [256];
int nFoo = someFunction(...);
sprintf (szResult, "nFoo = %d", nFoo);
m_myEditCtrl.SetWindowText (szResult);
CString strResult;
strResult.Format ("nFoo = %d", nFoo);
m_myEditCtrl.SetWindowText (strResult);
Hope this helps.

I understand now...
Everything works out perfect besides for: "m_myEditCtrl"
I appoligize for my illiterate-ness in MFC...
C:\*\ClientDlg.cpp(190) : error C2065: 'm_myEditCtrl' : undeclared identifier
C:\*\ClientDlg.cpp(190) : error C2228: left of '.SetWindowTextA' must have class/struct/union type
Other then that i understand what you mean and how it will work, but what am i doing wrong when it comes to "m_myEditCtrl"? What do i replace it with?

The m_ implies that it is a (CEdit) member variable of the CClientDlg class.

m_myEditCtrl is a CEdit member of your dialog class, declared in the dialog's .h file. You will also need to associate the member with an edit control in your dialog template.
You can do this dragging an edit control into your dialog template (using the resource editor) and using the ClassWizard to associate the CEdit member variable with the control.

Im still alittle Queued... In class wizard when i go to Member Variables the only Class ID's listed are "IDCANCEL" and "IDOK" the only choices i have are "Add Class" and "Add Variable"
When i click on Add Variable it says "Member Variable Name: m_" where im guessing i put m_myEditCtrl... the only Catagory is "Control" and the only variable type is "CButton" but i dont want it to be a button?
"m_myEditCtrl is a CEdit member of your dialog class, declared in the dialog's .h file." Where and what would i put in CButton01Dlg.h? (would this change my Class ID list to allow me to add it?
"You can do this dragging an edit control into your dialog template (using the resource editor)" Resource Editor?... Dragging an edit control into your dialog template?... Im so Lost =/
Sorry again...

You need to first add an edit control (eg: IDC_MY_EDIT) to your dialog template using the resource editor. Next, use the ClassWizard to add the m_myEditCtrl variable (category = Control).
Since you're new to VC++, you may want to refer to an introductory text to help you get going. Meanwhile, see this[^] link to see how to add controls to a dialog template.

It looks like the forum ate one of my replies. In answer to your question about the Control toolbar, here's how to display it:
In VS2003, do View|Toolbox. In VC6, double-click the dialog in Resources tab, then right-click the workspace and select "Controls" from the popup menu.

Why recommend sprintf ? What's wrong with stringstream or even CString.Format ?

It was the closest thing to printf() which he's familiar with. In my later post I recommended that he use CString::Format().

No, those are for console-based applications.

Hi everyone,
I'm currently working on an FFT App which gets the Input about the Mic. Once the Mic Buffer is full the Function void void CWaveCtrl::Update(const Fft &FftTransformer) in my Static control is called. Now lets come to the problem. In the Function I can't call GetClientRect() or Invalidate(). I don't know if the problem only exists with those two Functions. This are the Functions i would need  The Program always crashes with:
Debug Assertion Failed!
Program: ...\Visual Studio Projects\FFT\Debug\FFT.exe
File: f:\vs70builds\9466\vc\MFCATL\ship\atlmfc\include\afxwin2.inl
Line: 135
Please Help. I have no clue.

I did and it just seems like the Functiun is unable to get the correct HWND.
I can't be more precioses because when i click retry to debug my system is vveeerrrryyyyy slow 'cause of the bug. But in the Locals Watcher i can see that GetClientRect(rect) return the right Rect Values. Here is the Complete Function:
void CWaveCtrl::Update(const Fft &FftTransformer)
{
CRect rect;
GetClientRect(rect);
int iMaxPoints = min(FftTransformer.Points(),FFT_POINTS * 8);
for(int i=0; i < iMaxPoints; i++)
{
int s = FftTransformer.Tape(i) / 512 + (rect.bottom - 1) / 2;
if (i >= rect.right)
{
Add( i, rect.right - 1, (rect.bottom - 1) / 2);
}
else
{
if ( s < 0 )
Add (i, i, 0);
else if (s >= rect.bottom)
Add (i, i, rect.bottom - 1);
else
Add (i, i, s);
}
}
}

I'm using this class in my UI thread (which has no dialog, so I needed to make a timer) so that I could fire off 3 different timers. I was wondering is I should wrap the postmessage as well as SetTimer and KillTimer as a critcal sections. My main app will be creating 3 threads that will be creating three timers. Would this help in making sure I did not step on another thread accessing TimerProc at the same time.
Here is the link to the class I'm using.

Would it hurt anything to give each thread its own timer function?

Well basically each thread is dirived from the CWinThreadTimer class. So it does have it's own timer function. I was under the understanding that the TimerProc used the same memory space regardless of what thread created it. is this not the case.

Just a suggestion, ignore me if I'm totally off base, but why not create a hidden window for the thread that will handle the WM_TIMER message? That way the window's message queue will take care of all those problems.

Good question. While at first i was attempting that, I figured it was more of a hassle dealing with a dialog that was modaless and modal.....blah blah blah. So it was easier too make a timer call....by the way this work great. I'm running three threads with each having 3 timers. That's 9 timers going, and it works great. I just want to make sure that then do not step on each other in memory.
Thanks
