What do you mean by "Interface" name? Do you mean a COM interface, or a name of the exe/process? Can you clarify?

This interface does not ring any bells, but in any case, Internet Explorer has many interfaces, depending on what you want to do.

A few that come to mind are:

IShellView
IShellFolder
IShellBrowser
IShellDetails

What version of Visual Studio .NET are you using? 2002 or 2003?

Hmmm... To be honest, I am not sure. If this project of yours is written in Managed C++, then I suggest that you try posting about your problem in the Managed C++ forum and see if someone looking there might be able to help you. Best wishes.

If it's a true fisheye with 180 degree FOV, conversion to rectilinear would result in an infinite image. If you want to convert a segment cropped from the fisheye image, first you need to know the projection used by the lens. Equisolid angle and equidistant projections are the most common. You can get the projection equations from http://www.root.or.jp/fit/pages/gyogan_eng.htm[^] or http://www.lce.hut.fi/~jkannala/Kannala_Brandt_ICPR2004.pdf[^]. Then reverse the fisheye projection and apply the normal perspective projection instead.

Structure declaration

I'm wondering what's the usage of the following "tagHELLODATA". Is it for reference inside structure declaration? Can anybody gives me a example?
Thanks

typedef struct tagHELLODATA
{
UINT iColor ;
COLORREF clrText ;
}
HELLODATA, * PHELLODATA ;

Hi,
That is nothing but a tag/name of the class.Here

HELLODATA data; //creating object-data of type: struct tagHELLODATA

if we refer the structure via typedef struct pointer:
PHELLODATA ptrToHD; //struct tagHELLODATA* ptrToHD

That's the actual name of the structure. You can skip that in the declaration, IIRC. One place where you need it is if you need a reference to the struct from within the struct itself (for eg, a Node in a list).

typedef struct tagNode
{
   struct tagNode *next; //Can't use Node here.
}Node;

AFAIK, the tagHELLODATA is not strictly necessary here. In this case, declaring a variable

HELLODATA foo;

has the same effect as declaring it like so:

struct tagHELLODATA foo;

. I believe you can dispense with the tagHELLODATA, changing the declaration to

typedef struct
{
UINT iColor;
COLORREF clrText;
}
HELLODATA, * PHELLODATA;

should not cause any adverse effects.

The best way to explain is by example:

Lets say I want to have a structure called BOB that I want to use in both C and C++.

In C++, I can do the following:

struct BOB { int a };

and then to use BOB I just say:

BOB myVariable;

In C, if I do the following:

struct BOB { int a };

I have to say:

struct BOB myVariable;

So, in order declare a variable in C like you would in C++, people did the following:

typedef struct tagBOB { int a } BOB;

Now in C you can do "BOB myVariable".

Since windows h files are for both C and C++, you still see the "tag" stuff for C which doesn't hurt C++.

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

Problem with MFC DLL and mixed VS-Versions

7-Apr-05 22:47

Hello,
I writes a MFC application with VS 2003. A part of application uses a MFC-extended DLL.
This DLL was written with VisualStudio 6.x. Now I have a silly problem that when I debug my application (with the debug-version DLL), the debugger fails when I access the the DLL. If I compile the DLL with VS 2003 everything works well.
Does it make a difference with which version of VS the DLL is compiled?
Applies this problem only to Mfc dlls?

many thanks...

Assign ODBC Recordset to an object

Hi all!

I am developing an application using MSMQ and i want to send a recordset object using it. now my problem is how can i fetch all records in an recordset object. I have using ODBC and my database server is Microsoft SQL . Whenever I open recordset, i want that whole recordset will assign to an object.

Is there any way I can ensure that all records from a record set will assign to an object ?

Any help would be greatly appreciated!

Thanks,

Rajan

A CRecordset object does not contain the record set itself. It simply provides you with methods for accessing it. Use the MoveNext() method to iterate through each record of the set, and add each record to a list/array of some sort.
