It works. Thanks a lot!

When I use STL class (for example, map), there are always a lot of complie warning. They have NO relation with my program, for example, the following compile warning.

"C:\program files\microsoft...

Suppose a more complicated case:

class SimpleGA
{
void Step();
virtual bool done() = 0;
virtual int ObjectiveFun() = 0;
}

class SteadyStateGA

I developed two classes, which represents two kinds of algorithm, like the following:

class SimpleGA
{
void Step();
virtual int ObjectiveFun() = 0;
}

class SteadyStateGA
{

Suppose the circle rotates around X-axis for 30 degree, then rotates around Y-axis for 45 degree, then rotates around Z-axis for 75 degree. VC can NOT provide API to draw an ellipse whihc reflects...

Do you mean VC can NOT implement rotation in 3D space?

I draw a circle in the screen. After I rotate this circle around X-axis or Y-axis (in 3-dimension), it will be an ellipse in the screen. Does VC provide API to drawn such kind of circle? For...

In VB, we have a function named InputBox() to let user input text in a message box. Does VC have the corresponding function? Thanks.

Thanks a lot!

There are three buttons in the dialog. In the runtime, I want to make one of them invisible when some codition is met, and visible again when other condition is met. But I can NOT find a member...

You are quite right. What I want to do...

Actually, it is quite possible that IP address of host name is wrong in hosts file. For example, IP address of host A is saved in hosts file previously, then host A changes IP address. Now IP...

Normally API gethostbyname() can get IP address by host name. But this API has a serious problem: it retrieves IP address from file WINDOWS\system32\drivers\etc\hosts firstly. It will search...

nobody knows the solution?

I use Visual C++ 6.0 to write an ISAPI extension program and a service program. There are some bugs in them, but I don't know how to debug such kind of program. I want to set a break point in the...

Here is my program. Program arguments is "test".

#include <tchar.h>

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
for(int i=1; i<argc; i++){
_tprintf(_T("%s"), argv[i]);
}

I am trying to dubug a program. I have the source code of both parent class and child class, but they are in different Workspace. I press F10 to follow the execution flow, and when I meet a...

I see. Thank you very much.

ClassA.h

template <class T, int n> class ClassA

I want to use template in my program.

First, I define a class.

template <class T, int n> class ClassA
{
public:
ClassA() {size = 0; }
virtual ~ClassA() {}
void Insert(T x);

Sure, we can ignore the error. But isn't there a method to detect whether the user close the Word doc not not?

No, what I mean is how to know whether the user close the Word doc or not. You see, in the Command1_Click() event I use automation to open the Word doc. After the user read it, he may close the...

I use following code to open Word file:

Dim objWD As Word.Application
Set objWD = CreateObject("Word.Application")
objWD.Visible = True
objWD.Documents.Open FileName, , True

Then use...

Thanks!
I just want to know how many lines my code has:)

Sometimes when I am writing the code, I want to know the current line number. How to make the Visuall Basic editor show the line number? Thanks.
