hi, I have a sql in my program. What I want is exactly like this:
select *
from tbl t
where t.name like '%xyz%'
So in source code, I create sql like this:
CString name = "xyz";
::sprintf_s(szQuery, " select * from tbl t where t.name like '%%%s%%' ", name);
Here is szQuery when I execute
select *
from tbl t
where t.name like '%x%'
Just the first character is printed into szQuery.
What's wrong here? what should I do??
Thank you in advance.

Do you have UNICODE enabled ?
|
|
|
|
|
yes, Cedric. It's a Unicode project. In Project properties, The Character Set is "Use Unicode Character Set"
is that wrong?
|
|
|

Then you have to specify %S instead of %s. CString will return a wide-character string since UNICODE is enabled. If you look at the format specification[^] you can see that %S tells printf that the string is a wide-char string (when used with printf alike functions).

Thank you, Cedric.
I just change the Character Set property to "Use Multi-Byte Character Set" and it's ok now

I think your project is a unicode project. So the CString will be holding a pointer to unicode string. So you the following options.
1. use _stprintf_s() intead of sprintf_s( in this case szQuery also need to be TCHAR* or TCHAR[] ) or
2. Use CStringA instead of CString or
3. Convert CString content to multibyte characters using WideCharToMultiByte() API.
4. Undef _UNICODE.

5. Or simply use %S instead of %s 
|

nice!!
If we use "Use Multi-Byte Character Set", it should be "%s".
Or if we use "Use Unicode Character Set", it should be "%S".
Thank you, Cedric!!

I will try them now. At least the option 2 works
There 're many functions similar to each other. It's so messy, and not easy to understand .... 
Thank you, Naveen.

I have a base class A which is being inherited later & in one inherited class i had OVERLOADED one of the base class function.
The code snippet is given below.
class A{
public:
virtual void fun(){
cout<<"A";
}
};
class B: virtual public A{
public :
void fun(){
cout<<"k";
}
};
class C: virtual public A{
public:
int fun(int num){
cout<<"C";
}
};
class D: public C, public B{
};
void main(){
D dObj;
dObj.fun(4);
}
Can anyone tell me why i am getting an "ambigous" error in the fn call?
|

thenewbee wrote: dObj.fun(4);
The error came because the compiler (me also)dosent understand which function it should actually call. function of A, or B or C. Actually which class' function do u expect to get executed?
|
|
|
|
|
The call dObj.fun(4) shld call C::fun(int)
Thats wt we had learned from the concept of Overloading. .
Am i correct??

no. First can u tell me why didnt you expect B::fun(int) to get called. Both B and C are base classes of D. Isnt it..? is it because C is your favourite ?
|
|
|
|

virtual void fun(){
cout<<"A";
}
};
class B: virtual public A{
public :
void fun(){
cout<<"k";
}
};
Its not becoz C is my Fav. . 
The base class B dont have fun(int). But C have.
& how will B get the fun(int)??

First state my invironments: OS xp sp2, vc6.0
I create a dialog based MFC program, in the CMyDlg class, I type CTRL+W to invoke the ClassWizard,
I couldn't find some messages like
WM_NCHITTEST, WM_ENDSESSION, WM_QUERYENDSESSION
messages in the MESSAGE MAPS.
I should manually add these message handles.
Does anyone knows why?

In the class wizard, take the last tab( Class info ). In it there will be a "Message Filter" Combo box. By default for a dialog class, it will be having value "Dialog". Change it to "Window".
Now if you took the the "Message Map" tab, all the above messages will be present

when i call this function main dialog box in which i want add tabcontrol
on clicking on each tab a dialog should appear
but GetParent() do not working
int m_DialogID[2];
CDialog *m_Dialog[2];
m_DialogID[0] =IDD_DIALOG1;
m_DialogID[1] =IDD_DIALOG2;
m_Dialog[0] = new tab();
m_Dialog[1] = new graph();
//when i call this from parent geparent genrate problem
void MyTabCtrl::InitDialogs()
{
m_Dialog[0]->Create(m_DialogID[0],GetParent());
}

What was the return value of GetParent?
How did you create MyTabCtrl's instance (i.e. is it child of the main dialog)?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

tab is my class name to tabbed dialogbox
m_Dialog[0] = new tab();
m_Dialog[0]->Create(m_DialogID[0],GetParent());
MyTabCtrl in my own class inherit from CTabCtrl class
