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?

How to create a custom control at runtime?
Thanks.

Call the control's Create() member function.

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.

Hi,
Please show me how to append text into the editbox.
I have a editbox, with has the associated variable:
CEdit m_Edit;
CString m_StringEdit;
I use this function to display text in the editbox:
void CMyEditClass::DisplayOnDebugWindow(CString debugdata)
{
UpdateData();
m_StringEdit = debugdata;
UpdateData(FALSE);
}
the problem is each time, when I use this function, only the new debug data is displayed. The current display data in the editbox is flushed out. I want to append the new debugdata into the editbox. Please show me how to do this.
Thank
Jim

CString text = m_Edit.GetWindowText();
text += NewText;
m_Edit.SetWindowText(text);

Hello,
I am able load image (*.bmp,*.tiff,*jpg)on Cstatic picture control using gdi+ API graphics.Drawimage() and it fits to my cstatic resized box of MFC dialog based application.
when i load large images of size 80MB or 1GB tiff it takes hell lot time
and i need to process it using my interpolation algorithm for getting result image this goes double the time of loading. made me unconsiderable code/appln.
so i decided to copy only Cstatic loaded images for algorithm process stucked up how to copy image data with reduced image size.
please help on this regard
thanks in advance

It's a member of the dialog class, or the CFrameWnd class if you are doing an SDI or MDI application.

In the class' declaration, which is usually the .h file.

hi,
i've got a pretty simple question about comboboxes. i want to make the combobox 'read only' so that my code can still add items to it, but the user can't add his/her own things to it. does anyone know how i can do this?
thanks in advance,
sam kline

It's actually one of the comobo box styles, I think it's called 'Simple dropdown'. Depending on your IDE version, there is a property somewhere for this.
