Perhaps you should check out that post. You suggested gethostname(), which I indicated was to get the name of the local machine only. See the difference?

HI,

I have some value in string object like

CString str = "ABC"

I want to create an array with the name that is the value in the string object, in the current exapmle it is "ABC"

so it should be

CObArray ABC;

How can I do this? That define a name of an aray that is the value got from some where.

Thanks

Regards.

You can't.

The best solution would be to dynamically create the array and add it to a map using the name.

Find out how to use the MFC CMap<> or the STL map<>.
Use the MFC CArray<> or the STL vector<>

Eventually you will do something akin to mymap.Add(string, new CArray<>());

Like said by Joe, you can't. But there is surely another solution to your problem. Maybe if you explain us what you want to achieve exactly, we could find a solution.

Thanks, but this didn't help me. My problem is i needed to a get a value(user selects) of one property page to another property page during runtime for validation purpose.
Could you give me a idea pls

Look under Notifications, especially NM_CLICK, TCN_SECHANGING and TCN_SELCHANGED.

ActiveX problem

I have an ActiveX control (.OCX) which will be used in normal HTML page. So far so good. But, I am not able to use this from within a .NET application. When that page is loaded, an error pops up telling there was an unsafe item and was blocked from running. The following is the exact error message. "This page provides potentially unsafe information to an ActiveX Control. Your current settings prohibit running controls in this manner. As a result, this page may not display correctly."

I have tried modifying all the security settings to low, manually in IE. Doesn't work still! How do I make it a safe control so that it wont display such a warning or it will not be blocked? Any help or pointers in this direction is highly appreciated.

Regards and thanks,

The control needs to implement IObjectSafety so the container can query it to see if it's safe for untrusted clients.

struct problem

Hi All,
I need to implement this,
typedef struct
{
T1 m;
T2 m;
T3 m;
........
}XX;
XX a;
....
note T1,T2,T3... has no basic class, I hope
a function can auto visit the data member one by one like this

for(int pos=0; pos< size(pos);pos++)

//size function get struct data member number
{
.......
stmt.setParam(pos, getData(pos));
//getData function get struct data member by pos
.......
}
I only want to use struct please do no tell me use vector or list

thanks a lot
i hope some one can do it although it is not easy

Unless all the members of the structure are the same type, it's extremely difficult. At runtime, the structure is just a single block of memory; the compiler sorts out which offsets into the memory to use at compile time. If your members are all the same type, you can calculate the address of each member like this (assuming they're ints):

address = struct_addr + (pos * sizeof(int));

where struct_addr is a pointer to the structure and pos is the index of the structure member.

Why don't you want to use a vector or list? You're trying to store an array of data, so why not use an array?

Even that calculation won't work if the packing size was, say 8 bytes. What he's asking for can't be done in a nice implementation-independent way.

Ugh. Yes, of course. Thanks for reminding me.

Although if the types are all the same, and you assume the packing is the same between each member it can be done similarly:

address = struct_address + (pos * sizeof(struct_name) / member_count);

It still isn't a good idea though.

I got a C++/CLI answer
why c++ did not add this function when designing

using namespace System;
using namespace System::Reflection;

public ref struct Record
{
String ^ name;
int age;
};

int main(array<system::string ^=""> ^args)
{
Record ^ rec = gcnew Record;
rec->name = "George Washington";
rec->age = 274;
array<fieldinfo ^=""> ^ fieldInfo;
Type ^ recordType = Record::typeid;

fieldInfo = recordType->GetFields(
static_cast<bindingflags>(
BindingFlags::Public | BindingFlags::Instance));

for (int i = 0; i < fieldInfo->Length; ++i)
{
Console::WriteLine("{0} = {1}",
fieldInfo[i]->Name,
fieldInfo[i]->GetValue(rec));
}

return 0;
}

That's not a C++ function - you're using the features of the .NET class library. It won't work anywhere but under .NET.

I still maintain that it's a bad idea - you're using a structure like an array, so why not just use an array?

Those are not errors. Those messages are just telling you that the dlls were loaded by your program, and that they do not contain any debugging information so the debugger will not be able to step into any code in those dlls.
