The procedure in your previous post is the correct way.
You should try the suggestions given there and follow up on that instead of posting the question again.

i use InternetOpenUrl (as async) to receive a file from a url.
this is the code i use :
BOOL CMyCode::RequestFile( LPCTSTR lpszUrl )<br />
{<br />
m_hInternet = InternetOpen(_T("MyCode"), INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, INTERNET_FLAG_ASYNC);<br />
if (!m_hInternet)<br />
{<br />
return FALSE;<br />
}<br />
<br />
InternetSetStatusCallback(m_hInternet, CMyCode::InternetStatusCallback);<br />
<br />
InternetOpenUrl(m_hInternet, <br />
lpszUrl, <br />
NULL,<br />
0, <br />
INTERNET_FLAG_RELOAD | INTERNET_FLAG_PRAGMA_NOCACHE | INTERNET_FLAG_NO_CACHE_WRITE, <br />
(DWORD) this);<br />
return TRUE;<br />
}<br />
<br />
void __stdcall CMyCode::InternetStatusCallback (HINTERNET hSession, DWORD Context, DWORD Status, LPVOID pInformation, DWORD InfoLength)<br />
{<br />
CMyCode* pThis = (CMyCode*) Context;<br />
if (!pThis)<br />
{<br />
return;<br />
}<br />
<br />
switch (Status) <br />
{<br />
case INTERNET_STATUS_RESPONSE_RECEIVED:<br />
m_dwNumytes2Read = (*(DWORD *)pInformation);<br />
break;<br />
case INTERNET_STATUS_HANDLE_CREATED:<br />
m_hHttpSession = * (HINTERNET *) pInformation;
break;<br />
case INTERNET_STATUS_REQUEST_COMPLETE:<br />
CompleteRequest();<br />
break;<br />
case INTERNET_STATUS_HANDLE_CLOSING:<br />
break;<br />
default:<br />
ATLTRACE(_T("Status is %ld\n"), Status);<br />
break;<br />
} <br />
}<br />
<br />
void CMyCode::CompleteRequest()<br />
{<br />
LPBYTE pBuff = new BYTE[m_dwNumytes2Read];<br />
ZeroMemory(pBuff, m_dwNumytes2Read);<br />
<br />
DWORD dwBytesRead(0);<br />
BOOL bOK(TRUE);<br />
while (bOK)<br />
{<br />
bOK = InternetReadFile (m_hHttpSession, pBuff, m_dwNumytes2Read, &dwBytesRead);<br />
if (!dwBytesRead)<br />
bOK = FALSE;<br />
}<br />
<br />
if (pBuff)<br />
delete []pBuff;<br />
<br />
Abort();<br />
<br />
}<br />
<br />
the code works ok only i have 2 major problems:
1. the file is received in a chunks of 267/268 Bytes each time i call InternetReadFile????
2. the CPU reaches 80% until the file is download completely

Have you checked the value of m_dwNumytes2Read bfore your call to InternetReadFile()?
|
|
|
|
|
what do you mean? can you give an example

You have the following code (btw could you edit your original message and put the code between <pre></pre> tags):
case INTERNET_STATUS_RESPONSE_RECEIVED:
m_dwNumytes2Read = (*(DWORD *)pInformation);
break;
void CMyCode::CompleteRequest()
{
LPBYTE pBuff = new BYTE[m_dwNumytes2Read];
ZeroMemory(pBuff, m_dwNumytes2Read);
DWORD dwBytesRead(0);
BOOL bOK(TRUE);
while (bOK)
{
bOK = InternetReadFile (m_hHttpSession, pBuff, m_dwNumytes2Read, &dwBytesRead);
}
The value of m_dwNumytes2Read is set when you process the INTERNET_STATUS_RESPONSE_RECEIVED message and is relevant to the status information, so it is probably less than the amount of data that may be available. Try resetting it to some bigger value before calling InternetReadFile() for example:
dwNumytes2Read = 2048;
LPBYTE pBuff = new BYTE[m_dwNumytes2Read];
DWORD dwBytesRead;
BOOL bOK(TRUE);
while (bOK)
{
bOK = InternetReadFile (m_hHttpSession, pBuff, m_dwNumytes2Read, &dwBytesRead);

thanks for the reply - it did solve the problem now the chunck are 2048 bytes each time - good!
the second problem still remains - high CPU about 80% - how can i solve this?
thanks again for your kind reply

First thing is to run some tests with different buffer sizes to see how that affects performance, 2048 was just a number plucked from the air.
Looking at your code I notice that you use ZeroMemory on the input buffer just before reading data into it; this is wasteful and serves no purpose, just allocate it with the new call.
Alternatively you could allocate your buffer at the beginning of the program, either via new or as a static data area. This would save repeated new delete[] pairs, and the consequent garbage collection code.
There may be other issues in the rest of your code, but I leave that for you to investigate.

Hi,
I want to know how to call an Crystal report using VC++ code in Visual Studio 2008. In Visual Studio 6, we use to have Project->Add to Project->Components and Control. This will enable us to add the Crystal Report component into our application. But I couldn't find a way to add Crystal report control into my VC++ application using VS 2008.
Please help me with this. If you have a sample code for VS 2005/VS 2008 that will help.
Thanks in Advance

Hi,
I am trying to write a multi-line string into an edit control on a
dialog box. I am using following code however not getting any success.
CWnd *pWnd =GetDlgItem(IDC_STATIC_MSGCNT);
CRect lpRect = CRect(100,100,20,20);
pWnd->GetWindowRect(&lpRect);
CEdit *pEdit = new CEdit();
pEdit->Create(ES_MULTILINE|ES_LEFT|ES_READONLY,lpRect,this,m_iEditCTLID++);
pEdit->ShowWindow(SW_SHOW);
CString str;
str.Format("%d",pWLSErrRpt->GetWLSMessageNo());
pEdit->SetWindowTextA(str);
Appreciate your help.
Thanks

Multiline editbox requires "\r\n" in the string to split the string into multiple lines.

No, you are writing a number to the control.

Hello,
I'm trying to develop a deskband/tray app using MFC. I guess there are more experienced programmers out there that might be able to help me. I wrote a simple spec what I need: http://www.kulone.com/contrib/utilproject/spec.pdf
I have some code already that builds under VS2008: http://www.kulone.com/contrib/utilproject/demos.zip
I'm looking for someone with experience developing C++/MFC apps, possibly experienced with deskband and tray apps. I can also pay a small fee for the solution ($700).
regards
Damjan

How to write C or C++ program that locks desktop icons placement? I have googled around it and all I found were commercial software or closed source software.
Any hints are welcome.
thanks!

The following answer makes the assumption that you are using windows XP/vista/7.
The following website should help:
http://www.activewin.com/tips/reg/desktop_3.shtml[^]
If you follow the instructions it locks the desktop icon(s); although it is still possible to rearrange them.
To accomplish this in a windows application you will need to use the registry api's(use the 'RegCreate' function(s)) here http://msdn.microsoft.com/en-us/library/aa383729%28VS.85%29.aspx[^] to create a registry key.
I tested this on xp and realised that I had auto arrange on, after turning this off it is no longer working.
I am now looking for the registry key for auto arrange.
I have code in c/c++ that can change the alignment of desktop icons on the (e.g. left align icons), I will post this if you want it.
