If it is bmp, ico(no compress), You need the pic file 'head description', then jump to you place to read part of pic!
But compress pic data can't be read part!

EOF isn't actually a character in the file, it's something handled by the OS. It sounds like you're opening a binary file in text mode, so any bytes in the file that are 26 are interpreted as EOF (back in the DOS days, EOF was stored in the file as ^Z but only text files). Open it in binary mode so you can read the raw bytes without the OS or CRT doing any interpretation of the contents.

HI there  ,
Normally FTP Server breaks a connection if it is idle for a specified time period.
How can a FTP client know about the break up of connection due to time-out?
Is there any api, or is there any trick involved?
I am using WinInet classes such as CInternetSession, CFTPConnection etc.
Please heeelllppppp

well I don't think it is possible...

Yes, but its ugly. We did it for a project at work. You have to use COM, which means you have to use MS J++ (or J# now) and expose a COM interface to be accessed from the C++ side. I don't know it well enough to go through the details.
If you are using .NET, then you should probably be able to access the J# Java classes seamlessly. At least that's what I've been told about VS.NET though I haven't played with it much yet.
There are only 10 types of people in this world....those that understand binary, and those that do not.

Thanks a lot for showing me "a window of good hope".
I will go further on this way and if will found the way then I will write you.

Dear Guys,
Can someone help me how to display the Percentage ("25%") font inside a Progress Bar as the bar moves, the way it displays while installing some software.
Neel.

One solution is to derive a class from CProgressCtrl. A simpler solution is to download a module someone has worked on already. Look in CodeProject code section.

Dear Guys,
Can someone help me how to update an editbox control in a modeless dialog box on the fly. That is for example I've added this piece of code in "OnMouseMove" function.
CClientDC dc(this);
int xcordinate,ycordinate;
char str[100];
xcordinate = point.x;
ycordinate = point.y;
sprintf(str,"X->%d Y->%d",xcordinate,ycordinate);
dc.TextOut(600,20,str);
This code displays the X and Y co-ordinates on the fly in a SDI or MDI.What I mean by on the fly is you know, the way the number moves in a VCR while rewinding. The same functionality I would like to have inside a dialog box's edit box. I tried the usual m_edit=str; UpdateData(false) and SetDlgItemText but to no effect. It displays only the co-ordinate where the mouse was at first, but it doesn't update when I move it. Please Help.
Neel.

Are you sure that onmousemove is called inside your modeless dialog?

I may be going at this all wrong, but here goes: I wrote an app that uses tabs. I put a child dialog under each tab that hides and shows as the tab is clicked, in that child dialog I put a Listbox, then DDX_Contol'ed is to a CCheckListBox class. The listbox resource has fixed owner-drawn capability. I added AfxEnableControlContainer() in the WinApp InitInstance(). So here is my problem. I get an error when I hit the VERIFY(bitmap.LoadBitmap(AFX_IDB_CHECKLISTBOX_95)) statement under _AFX_CHECKLIST_STATE::_AFX_CHECKLIST_STATE() in winctrl3.cpp (VS .NET). This is all after I do the AddString() function for the box. I would assume that it's when it tries to paint. But why? and how do I fix it?

Sorry, I checked the mother of documentation, MSDN, and found my problem. I needed to derive my own class from CCheckListBox and call create(). This brings up an interesting question: why do I need to derive some classes and not others? I don't need to derive from CString and others but I do from CDialog and CCheckListBox. Is it that I need to derive when it has a WndProc()?
Thanks anyway.

Hi. I have a bunch of controls dynamically created in a CWnd and i want to jump between them with the TAB.
Just adding WS_TABSTOP to the dwstyle isnt working.
Is it because i have to be in a CDialog or CFormView (parent)class?
If so, is the best solution to emulate it by tracking the TAB button and using CWnd::GetNextDlgTabItem ?
Other related question: how do i set the tab order in dynamic created controls? Creation order?
Thanks in advance!

I think it should work with a CWnd. To set the tab order dynamically, call SetWindowPos, like this
pWindowBefore->SetWindowPos( pWindowAfter, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE );
where you want pWindowAfter to be the control that gets tabbed to when pWindowBefore has the focus and the user hits Tab.
Creation order should set the initial tab order, so if you create your controls in the order that they should be tabbed between, you should be OK. If you are using a fully custom control, there's some wierd issues with focus (like needing to manually call SetFocus when you get a WM_LBUTTONDOWN). I can't really remember the specifics, but mess around with the SetFocus, and see where it takes you.

I finally got some code to compile in visual studio .NET 2003, by using the #include <iostream>
using namespace std;
i.e. std::cout << "Hello world" << std:: endl;
It finally compiled, but i dont know how to execute it. please help.

choose "start" from the Debug menu.
-c
When history comes, it always takes you by surprise.

if you are using namespace std;, you don't need to specify the namespace again when using the cout stream. ie, just cout on it's own without std:: is fine.

I'm the poster...and a library called <beer.h> is not legal when you are using the new ones ... i.e. <iostream> and <string> when you put th ".h" in there it screws it up bigtime. I found I actually did get better results when i put in std::cout <<..... then if i simply did cout... Thanks anyways =) Also, to the first person, thank you too. Now i can execute my programs =) =)

Since I have overrided this call, I can no longer easily create multiple views in my CHTMLView MDI. I have done some searching but I am getting lost.
My overrided CMyappView::OnFileNew()
opens a CMyPropertySheet.
so my question, How can I open another view so I can send an html file to be viewed? So the user will be looking at the original view plus the newly created. Thanks

CDocTemplate::OpenDocumentFile opens the specified document for you. So if you've created an appropriate doc template, calling this function will succeed. So could it be the doc template added in the InitInstance of your app.

RUNTIME_CLASS(CJSMLB03Doc),<br />
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CJSMLB03View));<br />
AddDocTemplate(pDocTemplate);
Now I am having a problem, mostly on my part, correctly calling the OpenDocumentFile function.
example:
pDocTemplate->OpenDocumentFile(....<br />
pDocTemplate::OpenDocumentFile(...
etc. Plus can I only call this in MyClassDoc or can I also call it in MyClassView?
Thanks again.

It's no static function, so the former way is correct (pDocTemplate->OpenDocumentFile() ). And it can be called from nearly everywhere you want - you only need the pointer to the doc template.
