Hello friend,

I need to show one small "Please Wait.." image screen whenewer some back end processing is in progress.
For e.g. whenever user changing his ip adress and port, before going checking and establishing the connection, I want to show a "Please wait ..." image.But while going for connection browser gets hangs because of connection and after connection checking is completed. It goes for next page.

I am using IWebBrowser2 interface through which, I am getting pointer of browser.Then I am using IHTMLELement through which I am getting pointer of current html content.After that I am using IHTMLImageElement to add one img tag inside current html page for please wait screen.

Please give me some suggestions.
Waiting for the positive reply

Thank you.

Hi,

When im using the below code

SHFILEOPSTRUCTW sh;

sh.hwnd = GetSafeHwnd();
sh.wFunc = FO_DELETE;
sh.pFrom = L"C:\\Documents and Settings\\Myid\\Local Settings\\Temp\\Tester";
sh.pTo = NULL;
sh.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
sh.hNameMappings = 0;
sh.lpszProgressTitle = NULL;

SHFileOperationW (&sh);

im getting the error...
cannot delete file:Cannot read from the source file or disk...

and when im using the SHFILEOPSTRUCTA it is deleting.... can u plesase tell me what"s the difference in these two ....(SHFILEOPSTRUCTW and SHFILEOPSTRUCTW)...and i have to use unicode only.....

both are same.

Well, Why do you choose unicode or Ansi version by yourself? just use SHFILEOPSTRUCT + SHFileOperation() and enclose strings in _T() macro. So that the unicode or ansi version will be selected automatically. For instance,

SHFILEOPSTRUCT sh;

sh.hwnd = GetSafeHwnd();
sh.wFunc = FO_DELETE;
sh.pFrom = _T( "C:\\Documents and Settings\\ICS400758\\Local Settings\\Temp\\Tester");
sh.pTo = NULL;
sh.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
sh.hNameMappings = 0;
sh.lpszProgressTitle = NULL;

SHFileOperation (&sh);

Regards,
Jijo.

I think I may have found your issue...

MSDN wrote:
pFrom
Address of a buffer to specify one or more source file names. These names must be fully qualified paths. Standard DOS wild cards, such as "*", are permitted in the file-name position. Although this member is declared as a null-terminated string, it is used as a buffer to hold multiple file names. Each file name must be terminated by a single NULL character. An additional NULL character must be appended to the end of the final name to indicate the end of pFrom.

You don't give an additional NULL, so the shell operation carries on looking for the next string... which will be gobbledegook at best. I think the compiler is adding padding, which is why the next character stands a better chance of being NULL in the ansi version then the unicode version. This theory is very handwavy and untested, but you are not following the manual either way.

So, try:

sh.pFrom = T("C:\\Documents and Settings\\Myid\\Local Settings\\Temp\\Tester\0"); // Give it an extra NULL.

Less importantly, I'd write

sh.hNameMappings = NULL;

MSDN wrote:
...Treat hNameMappings as a pointer to a structure...

It's the same thing really, but it will help you in a years time and you come back to read the code...

Hope that helped,

Erm...

If I'm not mistaken, didn't *you* write the code that you're now asking me about?

Shouldn't you be telling *me* what it means?

It's all well and good cutting and pasting code from other places, but you need to read the documentation first. I can forgive missing the extra NULL at the end of the string - it's a bit subtle, but I can't forgive not bothering to read the manual for a function you're having trouble using.

If you don't have MSDN installed on your PC... follow this link:
http://www.lmgtfy.com/?q=msdn+SHFILEOPSTRUCT[^]
and then read the hwnd part.

Good luck,

Iain.

No you don't create something known as multithreading or neither call it. It's a concept where you instantiate multiple threads, allow them to run, synchronize them and blah blah....
You will find some excellent articles on multithreading on Code Project. Just use the search window
If you are calling the same function on the same thread than it is not multi threading.
You can use a while loop inside the thread function and call the required function as many times as you need.

You need to google first, if you have "It's urgent please" mentioned in your question.

Well, if it's so urgent, I won't type any code for you, I'd be too slow...

Instead, I'll point you at the http://www.codeproject.com/KB/tree/[^] section here on codeproject.

Do a search for drag, and this was the fourth entry (first was an advert!)

Hi,

I am C++ newbie so.... I was trying to derive an Object from CString

Since Derived Classes can access protected members I tried to access

m_pchData

When I got an errors message that m_pchData was undefined I tried to

qualify it by using CString :: m_pchData

When I got the following error message

I dont get I am using CString in afx.H not CStringT in afxstr.h

Error 1 error C2039: 'm_pchData' : is not a member of 'ATL::CStringT<basetype,stringtraits>'

m_pchData doesn't exist in MFC for VS 2005 or 2008. In these, m_pszData is private, but you have helper functions to access it.
