I suppose you were expecting me to provide an example of populating a combobox with the names of the 193 countries. I like typing but not that much!

BOOL Value?

Hello,
I have 2 modless dialogs and I need to send a BOOL value from dialog1 to dialog2 how can I do that?
And please show me as you are present this to a child ! )

Re: BOOL Value?

Maximilien28-Oct-04 2:58

Is the value passed when dialog2 is created ?

Are the 2 dialogs modeless or modal ?

Does the child knows how to pass a pointer of dialog1 to dialog2 ?

Or Does the child knows how to create dialogs and pass the BOOL from dialog1 to dialog2 when dialog2 is created ?

Derive both dialogs from a base class that owns the BOOL.

buddy,
simply SendMessage to that Dialog.

as you have Handle of Both Modeless dialog boxes
do it as this way.

::SendMessage(Handle of Dialog box to send,WM_USER+786,0,1);

and cast the Lparam value to bool to get result

Listen,

now if you have to create Two ModelLess dialog,you have two object of dialog
like this way

Dialog1 obj1;
Dialog2 obj2;

now Introduce a m_RemoteClass of type HWND; in both of class.

now if you create a Modeless dlg(as you have to create them before showing them),the dialog data member filed with there own HAndles.

like Obj1.m_hWnd & obj2.m_hWnd (these are public member of dialog Class and it is inherited by each of it inherited class.)

now pass the value of hWnd to each other like
//after craeting
Obj1.m_RemoteClass=obj2.m_hWnd;
Obj2.m_RemoteClass=obj1.m_hWnd;

now declare ON_MESSAGE HANDLER in your class
and handle the user defined message say WM_USER+78 ok

then Message_MAp of each dialog class
enter you function
ON_MESSAGE(WM_USER+78,OnMessage)

and create a function like this

void DialogClass::OnMessage(WPARAM wParam,LPARAM lParam)
{
//Your boolean variable that you need
this->m_bBool=(BOOL)lParam;

}

/// Now how to send message from one dialog to other

if it on button click and if you sending data from
Obj1 to Obj2

void Dialog1::ONClick()
{
//If you sending TRUE
::PostMessage(this->m_RemoteClass,WM_USER+78,0,1);
//if you sending FAlsE
::PostMessage(this->m_RemoteClass,WM_USER+78,0,0);
//as you already know 0 stand for FALSE and any //postive value TRUE
}

i know i am very bad at english,if problem still persisit you can mail me you code and i will rectify that my email is alok#efextra.com

Pass pointer to string as LPARAM, and then cast lParam back to string in message loop function!

You can use try-catch blocks in MFC to catch unhandled exceptions. Remember, all MFC exceptions are inherited from base class CException

Hi thank you for your answer !

The problem is that I want to manage a Win32 Exception and not a MFC exception ...

Do you know how to do that ?

How can I read an excel file?

Hi everyone!!

I want to read a table of a .xls (Excel2003) file from my Vc++6 application, how can I do it? It´s not necessary to open Excel, just read the file. If you know solutions for my problem, please tell me.

Thanks a lot!!! Big Grin | :-D

Today could be a great day!

if you know the layout of your table you can use FILE/fscanf, fopen etc....
if it's all a bit complicated you're off for some more difficult stuff like automation.

You can probably use CFile (and functions) instead of FILE/fscanf etc.

Search MSDN for more info.

good luck.

thanks for your answer Smile | :)

what I didn´t know is that I can read a .xls file as a .txt (e.g) with CFile functions. Is data processed in the same way?... Would it be better if I export the table as a XML file?

Now I´m trying to do it using automation, and collecting information from MSDN.

thanks
