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!

hello,
I would like to use try and catch (or __try and __except) to manage an exception which is "Unhandled Win32 Exception". Who can tell me how to proceed in an MFC environnement ?

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 ?
Thanks a lot for your help and have a nice day !

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!!!
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 
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

Hi,
I'm trying to implement bulk insert using CRecordset derived class.
I'm now in a position that I can bulk update and delete exists records, but can't add new. The strange thing is that I can add #x records where x is the number of exists records in that table. It means that the Open method of the CRecordset (actually the Move method) 'mark' something that make the allocated bulk buffer valid for add/update/delete operations, but when the table is empty no buffer records has this 'mark' and the add fails. The problem is that I can't find the way to do this 'mark' myself. I tried to change the status array values to SQL_ROW_PROCEED but it didn't work.
Can anyone please help ? code will be appreciated...

Hello, buddies,
My program is a Win32 screen-saver program(ie, .SCR file), during its running process, it will launch another Win32 program to do certain things, and after this screen-saver program exits, that Win32 program may pop up a window for showing some information to the user.
Here's my problem: on the WinNT-based platform (WinNT/2K/XP), when the screen-saver is set to be password protected (ie, the user needs to input the password to login the system after the screen-saver exits), the Win32 program which launched by the screen-saver is immediately terminated also when the screen-saver exits, so that Win32 program doesn't have the opportunity to show the information dialog.
It's seem that That Win32 program is terminated by the system when the screen-saver ends, and this's maybe relate to something like "desktop switch", because the password-protected screen-saver is running on the so-called "screen-saver" desktop, and the other program launched by the screen-saver is also running on this desktop, the screen-saver ends, the "screen-saver" desktop disappears, so the other program dies as well...
The above is my opinion for this problem, so I tried to do somethings like switch the desktop in the screen-saver and the other program, but failed, that problem still exists.
So, does anyone can tell me: How to let the another program still run after the password-protected screen-saver ends?
Thanks!

I have an MFC application that loads data from a database. I created a user interface thread based on CWinThread that displays a modal dialog with a text box and a cancel button. The user can click the cancel button to abort the load. The load takes place ( and the dialog is created ) in the OnNewDocument handler of the main app. The first time it works perfectly but if I click File New the UI thread gets stuck in the dialog creation code somewhere and the dialog is not displayed. When the load function completes it does a PostThreadMessage to the new thread sending a WM_QUIT message and waits for the UI thread to close. Because the UI thread is stuck it doesn't respond and the application stalls.
Any ideas?

Hi,
Put a break point @ on new document & Oninitdialog of the dialog and check where it is getting struck. Sometimes the callstack may give you more information regarding the location.
Have a look @ this link on UI Threads it will surely help you

This may help you

Make it a modeless dialog instead. Even if you do keep it in the secondary thread.
Then you can just hide and show it, and each time the OnFileNew is called, you won't have to keep trying to create/destroy a window.

hello...
does any of you have any idea how to hide or close the console window without terminating your whole process? I've been experimenting lately with Win32 console application with MFC support... My rpogram basically communicates with a RAID system through the serial port.
My program is already working fine but I wanted to hide the console window while my program is running. Is there a way to hide the console window and just display my UI?
if any of you have any idea, you can reply to this post or email me personally...
my email add is dimitri_sjp@yahoo.com
thanks !!!
