I am still not getting it
Please show me in stdafx.h what i should put, in MySample.cpp and MySample.h what I should put? There are about 10 files, say MySample2.h, MySample2.cpp, etc.. in those what I should put? Show me the code please. I have never done this before. Sorry if I am troubling too much.

MySample.H
extern CString strGlobal;
MySample.Cpp
#include "MySample.H"
// declare variable in ONLY one source file
CString strGlobal = "Initialization Value";
MyOtherSample.Cpp
#include "MySample.H"

Yes, I got it. As ....PJ Arends... said, I put #pragma once in all the .h files and #include "stdafx.h" as the first statement of all the .cpp files. Also I removed #include "PersonDlg.h" statement from the Person.h file. Now it works fine. But I have not changed the compiler option to "Not using percompiled header files..". Just I left it, as it is.
Thanks once again

There are many ways, it really depends on what your needs are. You can used the clipboard, memory mapped files, pipes, mailslots, DDE, WM_COPYDATA, or windows sockets, etc.
See the articles listed at http://www.codeproject.com/threads/#Inter%2DProcess+Communication[^]

If I create butons and statics in my normal window they do not match those in my dialogue boxes (the font is different).
I can change the font in main window but I don't know what settings to use. Arial doesn't seem right, anyone know what they should be?
Thanks,
Ali

Hi All
How to pass a function name as argument of another function
eg
void Test()
{
}
main()
{
Do(Test)
}

|
|
|
|
void Test() { printf("test\n"); }<br />
<br />
void Do(void fn()){ fn(); }<br />
<br />
int main(int argc, char* argv[])<br />
{<br />
Do(Test);<br />
return 0;<br />
}

You don't pass a function name as argument as another function but rather a pointer to a function:
First, you have to describe what is the 'type' of the function, for example:
typedef void (MyFunc*) (int,int);
This is a typedef that says that MyFunc is a type definition of a function returning nothing (the first void before (MyFunc*) ) and that takes two integer arguments (the argument list is specified after (MyFunc*) ).
Then, you can use MyFunc as a standard argument to a function:
void Do(MyFunc MyFuncThatWillBePassed)<br />
{<br />
}
This explain that the Do function will receive a pointer to a function of the type MyFunc as argument.
Inside your Do function, when you want to call your function, simply do that:
void Do(MyFunc MyFuncThatWillBePassed)<br />
{<br />
int a=0,b=0;<br />
MyFuncThatWillBePassed(a,b);<br />
}
Warning: you have to respect of course the type of the function and so you NEED to pass two integers (in our case) to your function otherwise you will have compile errors.
Hope this helps

it should be
typedef void (*MyFunc) (int,int);

My Google skills are failing me this evening; does anyone have any examples or pointers for creating Sticky windows? Basically what I want is to create dialogs that stick to each other like Win Amp’s play list editor and its main dialog.
Any help is appreciated.

I have a .DBF file. Is it possible to do some database operation on this file using ODBC on some machine where SQL Server is not installed? If so can you show me a small code sample? (The application that i use is written in Visual C++ 6.0)
Thanks

ODBC is just an interface - it has no engine for SQL Server.

Google Web accelerator highlights prefetched links with a double-underline, but I dont see the web page being modified. I know this application is a BHO, so can someone tell me how can a BHO modify the look and feel of the web page?
PS: What is the difference between BHO and a add-on?
thanks!
|
|
|
|
|
A BHO can basically do whatever it wants :p
A BHO sits in the browser app, thats outside the page, and add-ons are embedded in the page. For that reason BHOs has a wider view of things.

I have a try/catch block that is throwing an exception. What are the different things I can find out about the exception? line number, exception type, etc?
thanks!
|
|
|
|

simply put - what u throw is what u get.
try/catch are not defined to give info like line numbers, only what was thrown.
to get more info u'll have to use SEH, but then u lose unwind semantics...

What I do is to buld a string containing the value of __LINE__ and pass this to a global ThrowError function which packages this into an object which throw can throw.
For example:
class CMyError : public CException {
public:
const char * Message;
};
and somewhere in the code:
static CString s;
s.Format("File %s, line %d\nOverflow in addition", THIS_FILE, __LINE__);
ThrowError(s);
where ThrowError puts its argument into Message in an instance of CMyError and throws the CMyError. So basically I can send any information I want to via a throw.
