What could possible be wrong when CFtpConnection::GetFile(…) returns 5 (Access is denied). I know the file exists and I’ve got the right URL.
Thanks for tips

Hello Everyone,
A question related Form design with C++ in Visual Studio .NET 2003.
Scenario
I've one Form, let's call it MyForm, with various controls on it. There's a Panel on this Form on which the user can draw and edit a polygon. Now, the mouse event methods were becoming quite large, so it seemed like a nice idea to write a custom class (MyPanel) which is a child of "System::Windows::Forms::Panel". In this class I for example redefine the "OnMouseMove", "OnMouseDown" and "OnMouseUp".
Next, I changed one line in the "InitializeComponent" method of MyForm; that is, I changed:
"this->panel1 = new System::Windows::Forms::Panel();"
into
"this->panel1 = new Guillotine::CCanvas(this);"
Results & Problem
Now, the above works fine when I compile and run the application. However, I'm in real trouble when I start using the Form Designer. The Form Designer removes all the code related to the Panel, thus clearly does not accept any adaptations to the "InitializeComponent" method of MyForm.
NOTE: The MyPanel class can not be written as a stand-alone control, and then imported through a dll, since it "talks" to various other controls on MyForm!
Question
I realize that InitializeComponent is *not* to be adapted (according to the text preceding this method). However, the above change seems very natural, and the adaptation of the "InitializeComponent" is marginal. My question is whether I can let the Form Designer know that everything is ok with MyPanel (my self defined Panel class), and that the Designer can accept this child of Panel as a Panel?
Looking forward to possible approaches to tackle this problem (or on explanations why I should definitely *not* do this  )!

Hello!
I'm currently building an application which uses a kind of "magnifying lens" to zoom into a displayed DIB. I use the mouse to move this "magnifying lens", but I think the mouse pointer is quite annoying while zooming in, so I want to make it disappear.
Does anyone know a nice and convenient way to switch the mouse pointer on and off?
Thanks a lot in advance!

Yes I know the code for it.

Use LoadCursor() if you pass NULL the mouse pointer will be turned off.
To turn it back on again (standard arrow) use IDC_ARROW.

You could use the ShowCursor function.

Hi All,
I have a client application which is sometimes displaying the message "An unknown error occurred while accessing an unnamed file" before crashing.This message is being displayed very randomly and i could simulate this only once.
The scenario was like this:
1) The client and server are running in seaparate machines connected over a network.
2)Send some request commands to server and before the response is obtained,disable the network on client's side.
The message "An unknown error occurred while accessing an unnamed file" was displayed and on clicking ok the application crashed.There is no log of this crash also.Can some one tell me whether this related to CArchive and what should i do to avoid this or what protection code should i add to avoid crash.
The function CSocket::OnClose() is getting called immediately when the network is being diabled.But this function is not getting called when the above message is displayed and in such situation the application is crashing.
Thanks in advance
Regards
Raghu

Have you tried putting try and catch around your socket code?
In doing so you may be able to get a better idea of the exception.

Hi Folks!

I hope somebody can help me!

It is probably better to generate a DLL and then add the function into the newly generated code.

I have a list<basic_string> which only contains 2 items.
I have found tons of examples of iterating the list, but none for only dealing with 2 items.
How do I get the string values from the first and second element?
Thanks

Well, you could of course iterate the list also with 2 items in it...

std::list<std::wstring> strings;
strings.push_back(L"string 1");
strings.push_back(L"string 2");
cout << strings.at(0) << L" and " << strings.at(1); Might output string 1 and string2, if you are lucky.

Didn't work for what i'm trying to do 
typedef std::list<std::basic_string<TCHAR> > string_list;
string_list m_lsFiles; // List of selected file(s)
Later on somewheres deep within my code I call:
MessageBox(0, m_lsFiles.at(0), m_lsFiles.at(1), MB_OK);
How do I print my voice mail?

try:
MessageBox(0, m_lsFiles.front(), m_lsFiles.back(), MB_OK); A list is not a random access container, so you can not retrive elements with an index number.

Hah! What did I think of! I've been using to std::vector too much lately.

Tried it and I get this error???
'MessageBoxA' : cannot convert parameter 2 from 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' to 'const char *'

Combine what I said about using front() and back() with what Johan said below about using c_str() to get a char* from a string.
MessageBox(0, m_lsFiles.front().c_str(), m_lsFiles.back().c_str(), MB_OK); Do not give up on STL. It is quite cool once you get use to it.

Well, then, you should have stated what you were trying to do...
To get a pointer to a character buffer containing the text of the string object you use std::wstring::c_str(), as in
MessageBox(0, m_lsFiles.at(0).c_str(), m_lsFiles.at(1).c_str(), MB_OK);

I'm getting this error now 
error C2039: 'at' : is not a member of 'list<class std::basic_string<char,struct="" std::char_traits<char="">,class std::allocator<char> >,class std::allocator<class std::basic_st<="" i="">
WTF am I doing wrong??
I'm really starting to dislike STL
Thanks for the help

As PJ pointed out, std::list is not a random access container, which means it does not provide indexed access to items. I've been working too much with std::vector...
