It depends on how you want your GUI to look and function.
How do you want your GUI to look and what functionality do you want in it?
I suspect I would create a dialog-based application, or perhaps use CFormView in a SDI application if I want doc/view support.

It's supposed to be hard, otherwise anybody could do it!

Hi,
I think dialog based application is better, because you can visually place the components ( controls ) directly to the main window.

But how to create lines using drag and drop controls.

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.

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
