Post your programming questions here. I can handle csharp very well but I hope I'll be able to help. Good luck:-)

tnx, how do I populate a gridview by selecting an option from a dropdown which is in gridview itself

Click the edit items button, then select add columns. Then in the type of column, select combo box item. It's that simple.

@Dupsy, do you want to do this in code or using the Design view tools? By the way, Do you mean you want to filter the contents of the gridview by the selected value of your dropdownlist which also happens to be contained in the gridview?

Please how can populate a vector class with my user-defined class from STL in C++ and return it as method

Please how do i add a reference of a managed C++ project to another Managed C++ project in Visual Studio 2008?

@Kenkas: You can either compile it as a library and reference the library, or you can copy the contents of the other class and add it to your classes. I guess you want to use the first choice. To do this, start a library project and after you finish, compile the project(build the project). Then go to your main project that you want to import the project to. Go to your references in solution explorer and right click. You will see a tab for adding a project. Browse for the project and add it. Then in your main source file, add using [namespace of the imported project] You will then be able to use the classes in your library normally. Goodluck.

i like this , keep it up

pls hw do u assign a value 2 a textbox in data gridview?

I need SQL Server software. Anyone to help with it?

i have a little problem with java.

for(i=0;i<=10;i++)
{
System.out.println(i);
}
the output is 0 1 2 3 4 5 6 7 8 9 10
my problem with this is that it begins with 0. Now since i=0 and its less than 10, its supposed to increment it by one so the output should have started with 1.
I could just change the value of i such that i=1; but that would create another issue

ArrayList<Integer> points;
points = new ArrayList<Integer>();
System.out.println(points.size());

for(i=0;i<=points.size();i++)
{
points.add(i);
System.out.println(i+" The size is "+points.size());
System.out.println(points.get(i));
if(i==9)
{
System.out.println("Out ok";
break;
}


}
Now my array would start from 0 which of course i don't want.

if i>1; then would generate an exception


Problem 2: I wrote a program to roll a pair of die and count the number of rolls. The program would end if it gets a 1,1.

public class NewEmptyJavaApp2 {


public static void main(String args[])
{
int x=0;
int y=0;
int count = 0;
int count1 = 0;
int count2 = 0;

while(true)
{
x=(int)(6*Math.random()+1);
y=(int)(6*Math.random()+1);
count++;
if(x!=1 && y!=1) //Here lies the problem.if changed to || works well
{ count1++;
System.out.println("'"+x+"','"+y+"'";
}
else
{
count2++;
System.out.println("'"+x+"','"+y+"'";
break;
}

}
System.out.println("Total:"+count);
System.out.println("Non snake:"+count1);
System.out.println("snake:"+count2);
}
}

The problem here is the && operator. From my understanding && is supposed to evaluate both conditions but in this case if x=1 and y>2 the program would end which is totally incorrect.

Please could someone help me clarify these issues. Thanks.

@adewaleafolabi
I posted a response to your question on the other thread you opened.

Ok, Let me explain and let you have the load down of what am trying to do and what my problems are:
units grades points
1unit (A) 5
2unit A 10
2unit A 10
3unit A 15
3unit A 15
3unit A 15
4unit A 20
4unit A 20

Total unit = 22unit
Total points = 110points

GPA= Total points/Total units
GPA = 110/22
= 5.00
you see in this case i have the units specified but am trying to create a program where i do not know the amount of 1units or 2units that the user have in mind. How do i have the computer process for the units and add then divide just like i stated above. These are the declarations:
A=5
B=4
C=3
D=2
E=1
F=0,
Since its goin to be interactive e.g if a user has just 2 1unit course and maybe 4 3unit.

i have a little problem with java.

for(i=0;i<=10;i++)
    {
        System.out.println(i);
    }
the output is 0 1 2 3 4 5 6 7 8 9 10
my problem with this is that it begins with 0. Now since i=0 and its less than 10, its supposed to increment it by one so the output should have started with 1.

The last portion of the above for loop increments after each run, not before each run through the for loop. If you want your loop in the above case to start from one, then you can either do this
for(i=1;i<=11;i++)
{
System.out.println(i);
}

// Output in this case will be 1 2 3 4 5 6 7 8 9 10 11

Or
While(i<=10)
{
i++;
System.out.println(i);
}

@kobojunkie
thanks problem solved. Please could recommend me a book on java thats newbie friendly. I tried deintel but too much stories. Didn't like it.

I am not really a Java developer but I think a good Apress book on Java might be some place to start. I love the Apress books and I would think there are some on Java

Please is there anywhere I can get a sample project of api hooking using SetWindowsHookEx, I want to create a hook on CreateProcess using C#

Nice to know someone else is working on hooks. I hope its not a virus you are creating. You can give you your email and I will send you some private samples

hi, i want to create an online help in a web application, so that wen users press F1 they wuld be linked 2 help page. hw do I go abt dis using C#

pls i need C++ compiler and a brief tutoria on how to run my first program

Use the power of google dear. It's not that hard. Just search for dev C++ in google. Download the latest edition and install. It comes with the compiler. As for the tutorial so many websites are willing to show you once you are willing to use some effort
