Hi all
I have an application which calls another thread with own window procedure.
Inside that another window I put edit control.
My problem is that I can not type anything inside that Edit Control.
It looks, that it does not have keyboard focus.So, I tryed to work with SetFocus(), but it did not help.
Please answer my question.
Tahnks.

What kind of thread does the main thread spawn? In other words, the child thread should be a UI thread if you want to update the edit control.

hello
i declared function in one class that i creat ,public, but when i want to use it in an other class it say that's not declared.

|

Did you include the declaing header file into the callers?
Do Lipton employees get coffee breaks?
|
|
|
|
|
|
How are you using it in the other class?
Class A
{
public:
void AFunc();
}
Class B
{
void SomeBFunc();
}
void B::SomeBFunc()
{
A aInst;
aInst.AFunc();
AFunc();
}
Unless B is inherited from A.

This is exactly what I stated in my previous message. Even though you declared RePaint as a public function in foufou class you can't just use it in createfoufou. You need to call it this way:
class createfoufou
{
public:
createfoufou()
private:
foufou *newfoufouPtr;
};
createfoufou::createfoufou()
{
newfoufouPtr = new foufou;
};
void creatfoufou::setposition(int newX, int newY, int newZ)
{
newfoufouPtr->RePaint(randomX,randomY,randomZ);
}
// Afterall I realized that even my comment lines have bugs

when i must declare
<br />
void B::SomeBFunc(){ A aInst; aInst.AFunc();
in which class or file(.h or .cpp)

In createfoufou.cpp

I am not sure but my best guess is that these variables:
int STARTINGSPEED = 150;
int MINIMUM_SPEED =80;
int PANIC_SPEED =25;
using namespace std;
vector< foufou * > fou_caracter;
int num_fou_caracter;
have been declared somewhere else. Maybe in creatfoufou.cpp or foufou.h.

Is there a way to print out a warning when someone goes to use a function? I want it to be printed whenever (and only when) the function is referenced.

-OR-
__declspec(deprecated) void func1(int)

}

I'm going to patent thought. I have yet to see any prior art.

This seems to not work in g++ but thanks for putting me on the right track.

Is there anyway to have a class defined within a namespace, and still use a forward declaration? Take the following example:
class myclass;
static void function(myclass *p);
namespace abc
{
class myclass
{
public:
int i;
};
};
using abc::myclass;
Compiling this with VC++ 6.0, I get error "C2874: using-declaration causes a multiple declaration of 'myclass'". Is there anyway around this? Does using namespaces mean you can no longer use forward declarations?
Thanks for your help.

|

|

You have to declare it like this
namespace abc
{
class myclass;
}

 I have this dialog based project with a huge set of menus that I need to duplicate in my SDI. Can I just import them? If so how????? 
|
|
|
|
|
with the SDI project open, open the dialog project's .RC file. Copy the menu ID's and paste them into your SDI project's resource window. Simple copy and paste.

I have an application that is sending data through a serial port. That is working fine, but I am now to the point where I need to read from the serial port. I same across a CSerial Class developed by P J Naughter and it works quite well. I have played around with the Read() function and it works as long as you call it when you know something has already hit the port.
The application I am using this in is just a very simple dialog application. How do I setup an event handler that can interupt my program when a byte has hit the serial port? I have looked at some various resources without success. Does anyone have an idea that could help?
Thanks

One solution is to implement a non-blocking I/O model to communicate with the port. Microsoft published one solution using OVERLAPPED I/O.
