Yes I did select win32 console app proj, and i want a console app project but without the cmd window can it be done?
I need it for a kind of autorun for running other app without poping itself up on the screen.

I dont understand why u selected the console app proj.. any way try the following code
ShowWindow( GetConsoleWindow(), SW_HIDE );

Because when I try win32 proj the proj window pops up - is ther's a way to hide this window?

did ShowWindow( GetConsoleWindow(), SW_HIDE ); work for ur console application?

I haven't seen a window like that.( i doubt u have take "hello word application" )
Take a "Win32 Application" then in the next option select "Simple application"( I am using VC6 now. so i dont know if this is same in vc2005 )

The code didn't work I get an error.
but anyway even if it did this will be after the window pops up
In vs2005 after I choose win32 proj ther is no "Simple application".

After I choose Win32 new projectI get the options:
Application type:
Windows application - I get a win window popup
Console application - I get a cmd window popup
DLL
Static library
Additional options:
Empty project
Export symbols
Precompiled header
Add common header files for:
ATL
MFC
ShowWindow( GetConsoleWindow(), SW_HIDE ):
now i don't get an error but it just doesn't work:
in Console application - The cmd window popsup
in Windows application - The win window popsup
maybe ther is an option in the proj properties to hide the cmd window?

create a fresh Windows application. delete every thing inside the winmain() function. then tell me the result.

Ok It worked but it's not in winmain but in:
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
HWND hWnd;
hInst = hInstance; // Store instance handle in our global variable
hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);
if (!hWnd)
{
return FALSE;
}
//ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
return TRUE;
}
Thank you all

I have three classes all derived from the same base class. Is it at all possible for one class to call a function in another class? I'm guessing the base class would need to store a pointer to the derived classes, which in my opinion is a little messy. If there is an easier way to do this, please tell. Thanks.

didn't you ask this question last thursday ?
what's wrong with virtual ?
|
|
|
|
|
Not quite the same question, that was about a callback function in the base class. I tried the virtual method, but it doesn't seem to work. If I leave the definition empty, I get linker errors; If I set an empty method, the code only calls the empty method and not that of the redefined method in the other class.

hum, i think code sample will talk much than words
can you please show a brief piece of the code you tried, and explain clearly what you can it to do... thx

Sure, I know my English isn't all that great. Here's a very simplified example
class base
{
virtual DoSomethingElse()
{
}
};
class first : public base
{
void DoSomethingElse()
{
}
}
class second : public base
{
void DoSomething()
{
DoSomethingElse();
}
}

and then... you forgot the second part of my previous post ^^
what do you intend it to do ?

Haha. Think of a deck of cards. The base class represents the table where the cards will be used. The derived classes represent various actions with the deck of cards ( shuffling, dealing... ). One of the derived classes inparticular represents all the cards currently visible (face up) on the table. When a card is dicarded, I call a member function of my discards class to add the card to an internal array. I must also add the card to the list of visible cards. But rather than calling two functions, I want to know if I can automate this from the discard class by calling a member function of the visible class directly.
Again, this is simplified, there is a lot more going on in the background which I don't want to expose by creating un-necessary pointers.

If this is what you are trying to do, it sounds like you have a design flaw problem. Inheritence (public inheritance anyway) should follow an "is-a" relationship. What you are trying to do would be better suited for 2 collections (a collection of visible cards, and a collection of non-visible ones) with a manager to maintain the both. A class derived from the Deck of cards is not a good design for this problem.

Is there some problem in declaring a pointer to the first class in the second one:
ex :
class second : public base
{
void DoSomething()
{
first *pFirst=new first();
pFirst->DoSomethingElse();
DoSomethingElse();
}
}
Somethings seem HARD to do, until we know how to do them.

Yes because then I would have to pass the pointer into the class. Creating a new instance of the object will only lead to problems. But you did give me an idea, static!
Declaring the function and a few members as static has solved the problem.

Sure, if those methods (in the other class) are static.

Hi,
Can u plz help me to rectify the error.
1)If i write the code as shown below I am getting the correct results
SQLCHAR SQL[] = "SELECT EmployeeID,Salary FROM EMPLOYEE WHERE EmpName='tejaswini'";
2)If I write the code as shown below I am getting an error saying that error in execution.
What is the wrong with my code?

SQLCHAR SQL[] = "SELECT EmployeeID,Salary FROM EMPLOYEE WHERE EmpName=Str";
Plz help me.
Thanks in advance;

because the SQL engine is executing such query, as is. it is then searching Str as the Employee name...

Si Str va en el texto entrecomillado el ordenador lo interpreta como texto y no como tu variable.
Desconozco como funciona un SQLCHAR, si el texto fuera un CString deberías ponerlo así...
"SELECT EmployeeID, Salary FROM EMPLOYEE WHERE EmpName='" + Str + "´";
En este caso si cambiará Str por el valor de tu variable, además recuerda que en la sentencia Where EmpName= algo, ese algo tiene que ir entre comillas simples.
Espero haberte ayudado.
