It sounds like you expect this to be simple; in other words, like the IDE is going to provide it for you (Wrong!). You have two choices: (1) write a simple little piece of code that opens a file (for append/write) writes to it, then closes it, for each piece of your code (slow, but worth it), (2) If you are using MFC, then you can use trace statements, they will dump into the debug output window, which you can copy and paste to a text file.

I am a newbie to MFC and want to do the following:
I have a button added to a toolbar. I have also added the following in my code for the function to be executed once the Button is clicked: ON_COMMAND(ID_BUTTONRUN, OnRunTests)What I want is when the button is clicked I want the button state to be disabled and the cursor to look like a Hourglass untill the OnRunTests() is completed.
I tried the :ON_UPDATE_COMMAND_UI(ID_BUTTONRUN, OnToolbarRunUpdate)
but this got executed only after the OnRunTests() completed which is not what I want.
Is there a way for me to change the cursor and the button state as soon as the OnRunTests() is entered and change it back when it is done. Any help and guidance will be appreciated.

In resource.h:
#define WM_DOSOMETHING 12345//or whatever
In mainfrm.h, add a custom-message handler:
afx_msg LRESULT OnDoSomething(WPARAM,LPARAM);
In the BEGIN_MESSAGE_MAP macro in mainfrm.cpp:
ON_MESSAGE(WM_DOSOMETHING,OnDoSomething)
In the implementation for OnDoSomething:
LRESULT CMainFrame::OnDoSomething(WPARAM,LPARAM)<br />
{<br />
m_wndToolBar.GetToolBarCtrl().EnableButton(ID_EDIT_COPY,FALSE);<br />
m_wndToolBar.RedrawWindow();<br />
return 0;<br />
}
In your view class:
void CWhateverView::OnUpdateEditCopy(CCmdUI* pCmdUI) <br />
{<br />
if (m_bDisable)<br />
pCmdUI->Enable(FALSE);<br />
else<br />
pCmdUI->Enable(TRUE);<br />
}
In your function for long operation:
void CWhateverView::OnEditCopy() <br />
{<br />
m_bDisable = TRUE;<br />
BeginWaitCursor();<br />
AfxGetApp()->GetMainWnd()->SendMessage(WM_DOSOMETHING);<br />
int i, j,k;<br />
for (i = 0; i < 10000; i++)<br />
for (j = 0; j < 10000; j++)<br />
for (k = 0; k < 5; k++)<br />
{<br />
}<br />
m_bDisable = FALSE;<br />
}
And don't forget to declare m_bDisable in CWhateverView.h and initialize it as m_bDisable = FALSE; in the class constructor.
this is this.

Thanks so much for your explaination and sample. It reall helped me.
One question is : when I do BeginWaitCursor() it shows the hourglass for a fleeting second and again changes back to the arrow cursor. It does not stay as hourglass for the entire lengthy operation. Any help how to fix that?

Could i plot signal in the dialog box? Or it's more difficult to do it?
I wan to choose mfc AppWizard(exe).i wan to display button and boxes on the gui.What type of application is suitable to create ? sdi, mdi or dialog ?
Thx a lot for ur help. take care all.

every type of application can be content what you want,but more important is that you should write a derived class from CButton(for example),and override some virtual methods and message-functions.

when writting about "plot signal" do you mean drawing a graph of a signal, like an analogic signal ?
if so, have a look hhere[^] , there are examples on how to create graphs and plot.

No!
OK, that was simple, but you lost me. You need to rethink your question. It looks like you need a dialog based application.

I have a Fortran program related to figure plotting. Right now, I created a interface by Visual C++. Is there anyone who knows how to access Fortran program through the interface programmed by Visual C++?
|

|

Their is probably someone who can answer this question, but it is not me.
Rethink the question and give a little bit more imformation.
1) What Fortran compiler (or version) are you using (very improtant).
Blast! I could only think of one. But that one is important!

Define "access." Does Fortran support COM?

Hi
I need to display a dialog showing a message to the user and distroy it after a specific timeout.
How can i do this?
I'm familiar with threads but in other languages so just a piece of code would be very helpful...
Thanks a lot

Use EndDialog(TRUE) when timeout

Hi, all
I was trying to run an application cross network, and got this message "runtime error, program g:\...\cd.exe abnormal program termination" from c++ runtime library. but I was able to run it from another 2000 machine cross network on the same data. and could run the other exe on the same folder from my machine, too.
it just doesn't make sense why only this one won't work........anybody has idea?
thanks and have a good weekend!

that means the application has some bugs which are exposed in one machine and not the other.

 Oh, how I wish I could disagree, but you are absolutely right.
