You can do the same thing with CFormView.

Hi all,
I'd like to have my toolbar, should be movable only inside the main window, like MDI child window. But even in Visual Studio, it is possible to move the toolbar outside the main window. How can make it possible?
Thanks in advance,
Sarvan AL

toolbar is a popup window, which can be moved anywhere by default.
i think u can check toolbar's position in its WM_MOVE message to see if it is inside main window.
if not, u can move it to right place by MoveWindow() function.

Thanks includeh10,
Let me look into the alternatives.

You can use WM_MOVING instead of WM_MOVE. In that you can limit the movability.

SetForegroundWindow or BringWindowToTop.

What is the current dialog exactly ? And are you using modal or modeless dialogs (do you call DoModal) ? If you are using modal dialogs, then you cannot switch the focus between dialogs, you have to look for modeless dialogs instead.

How to write and read an object of user defined class say ABC into file.

|

Depends what you are using. Are you using the MFC's ? If yes you can look at serialization. And please, be more specific when you ask a question.

Hi anilksingh,
I used to write objects of my class, in the C way, using "fwrite". Here is the code snippet:
Regards,
Sarvan AL
class Student<br />
{<br />
int regno;<br />
char name[30] ;<br />
public:<br />
Student() <br />
{ <br />
regno = 0; <br />
strcpy(name, "NULL") ;<br />
} <br />
Student(int rno, char *tname)<br />
{<br />
regno = rno ;<br />
strcpy(name, tname) ;<br />
}<br />
void Display()<br />
{<br />
cout<<"Regno: " << rno << endl ;<br />
cout<<"Name: " << name << endl ;<br />
}<br />
} ;<br />
<br />
main()<br />
{<br />
FILE *fp = fopen("Test.dat", "wb") ;<br />
Student s1(1, "Robert"), s2(2, "Smith") ;<br />
<br />
fwrite(&s1, sizeof(Student), 1, fp) ;<br />
fwrite(&s2, sizeof(Student), 1, fp) ;<br />
<br />
fclose(fp) ;<br />
<br />
Student t ;<br />
<br />
fp = fopen("Test.dat", "rb") ;<br />
<br />
fread(&t, sizeof(Student), 1, fp) ;<br />
t.Dispaly() ;<br />
<br />
fread(&t, sizeof(Student), 1, fp) ;<br />
t.Dispaly() ;<br />
<br />
fclose(fp) ;<br />
<br />
}

why do you ask this on many forums ?
do you want to serialize your objects in Managed C++ or unManaged C++ way ?!

It's related to device drivers.

hey,guy,I'm confused when using dtpicker Activex control.dtpicker->GetYear()returns a VARIANT ,I write some words like below:
CString m_String;
m_String.Format("%d",m_dtpicker.GetYear().date);
but It returns some unknown interger,what's wrong with my code,how to use dtpicker get and put value?
Thanks.

Dear Experts,
I test such code in Visual C++ 6.0 as following:
#include <stdio.h>
#include <time.h>
int main()
{
char c0;
char c1;
char c2;
printf("%p\n%p\n%p\n",&c0,&c1,&c2);
return 0;
}
In "DEBUG" build mode without optimizationm, the output is :
0012FF7C
0012FF78
0012FF74
In "RELEASE" build mode without optimization, the output is :
0012FF7C
0012FF78
0012FF74
In "RELEASE" build mode with "Maxmize Speed" optimization, the output is:
0012FF7D
0012FF7E
0012FF7F
So, as above, in stack, there are redundant bytes in these "char" variables.
Why? Why Visual C++ compiler insert redundant bytes into stack?
Your Sincerely
REMY

I'm not sure but I'd guess it has something to do with char-to-int promotion.

1) User defined message is declared as Follows [ Defined in Both Sender and Receiver ]
#define TEST_MSG WM_USER + 1
2) The Message data Structure Declared [ In both The Application ]
class msgData<br />
{<br />
public:<br />
int msgNo;<br />
CString data;<br />
};
3) Window1 in App1 Sending the Message
void CTesterDlg::OnButton1() <br />
{<br />
HWND hw = ::FindWindow(0, "TestDCLeak") ;<br />
msgData * data = new msgData();<br />
data->data = "Sample Message" ;<br />
data->msgNo = 20 ;<br />
::SendMessage(hw, TEST_MSG, (WPARAM) data , 0 );<br />
}
4) The Following Message Map is Added in the AFX_MSG_MAP Section of the App2:
ON_MESSAGE (TEST_MSG, OnTest )
5) The Linkage b/t the Handler and the Message is Done as Follows [ In App 2] :
afx_msg LRESULT OnTest(WPARAM wParam, LPARAM lParam);
6) Window 2 in App2 Receiving the Message
LRESULT CTestDCLeakDlg::OnTest(WPARAM wParam, LPARAM lParam)<br />
{<br />
msgData * theData = (msgData * ) wParam ;<br />
AfxMessageBox(theData->data);<br />
return 0;<br />
}
* I can Find the App2 Message is Handler is Invoked & the pointer thedata in App2 is Equal to pointer
data in App1.
* But, I can't Able the get the data packed in App1, inside the App2..
Can Anybody Please Explain why this is Happened? What Correction I should take in Code?

These are 2 different applications ?
Then, forget about it because they don't share the same address space. You won't be able to share memory between two applications.
You'll need to go for another way to share your data. Either pipes, memory mapped files (I only used this one), or even files.
