I test MFC classes to download files from internet server , but how can I upload it ? Can I use the same classes / tehnique ?

Most likely, but since you did not show any specifics on how you were downloading, we can't say with any certainty.

Ok , here is my download code , which goes perfectly :
( I don't know if is corectly , but does function )
BOOL CMyDoc::GetXmlFile(CString sAddress, CString& sResult)
{
CString sTemp;
CInternetSession ISession;
CInternetFile* pIFile = NULL;
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
try
{
pIFile = (CInternetFile*)ISession.OpenURL(sAddress);
while(pIFile->ReadString(sTemp))sResult += sTemp;
pIFile->Close();
delete pIFile;
}
catch(CException* pException)
{
delete pIFile;
pException->GetErrorMessage(sTemp.GetBuffer(255),255);
sTemp.ReleaseBuffer();
pFrame->SetMessageText(sTemp);
return FALSE;
}
return TRUE;
}
I will be very glad if you can help me . Thank you very much !

So then can't you just use WriteString() to upload the file?

David , you are very prompt ! Thank you ! But , if I need to upload an file , don't need an login data to access upload server ?

Maybe, maybe not. Only you will know that level of detail. You might look into CHttpFile::SendRequest().

Maybe ( or for sure ) I don't understand something : I have an address to an server : 'http://www.testserver.com/testfolder/' and in this location ( path ) I want to upload an PC local path file :
'D:/Flaviu/test.txt' ... How can I adapt download code from above to write strings into server file ? First , create an mirror text file on server , and there write strings from PC local txt file ?

I found the solution , and for those hwo have the same issue , I post the code :
BOOL CMyDoc::UploadFile(CString sFileName)
{
CString sTemp;
BOOL bRet = FALSE;
CInternetSession session;
CFtpConnection* pConn = NULL;
CMainFrame* pFrame = (CMainFrame*)AfxGetMainWnd();
sTemp = sFileName.Right(sFileName.GetLength() - sFileName.ReverseFind('\\') - 1);
try
{
pConn = session.GetFtpConnection(_T("ftp.domain.com"),_T("username"),_T("password"),INTERNET_INVALID_PORT_NUMBER,TRUE);
bRet = pConn->PutFile(sFileName,_T("./httpdocs/temp/") + sTemp);
}
catch(CException* pException)
{
pException->GetErrorMessage(sTemp.GetBuffer(255),255);
sTemp.ReleaseBuffer();
pException->Delete();
pFrame->SetMessageText(sTemp);
}
if(pConn)
{
pConn->Close();
delete pConn;
}
return bRet;
}

Hi all,
i m working on vc++ and i have no idea of vb,i saw a vb application and want to do same functioning in my vc++
these are some function please help me to convert it in vc++
Shared Function Encode7Bit(ByVal Content As String) As String
'Prepare
Dim CharArray As Char() = Content.ToCharArray
Dim c As Char
Dim t As String
For Each c In CharArray
t = CharTo7Bits(c) + t
Next
'Add "0"
Dim i As Integer
If (t.Length Mod 8) <> 0 Then
For i = 1 To 8 - (t.Length Mod 8)
t = "0" + t
Next
End If
'Split into 8bits
Dim result As String
For i = t.Length - 8 To 0 Step -8
result = result + BitsToHex(Mid(t, i + 1, 8))
Next
Return result
End Function
Shared Function CharTo7Bits(ByVal c As Char) As String
If c = "@" Then Return "0000000"
Dim Result As String
Dim i As Integer
Dim ij As Integer
For i = 0 To 6
ij = Asc(c)
If (Asc(c) And 2 ^ i) > 0 Then //how write it in vc++
Result = "1" + Result
Else
Result = "0" + Result
End If
Next
Return Result
End Function
Shared Function BitsToHex(ByVal Bits As String) As String
'Convert 8Bits to Hex String
Dim i, v As Integer
For i = 0 To Bits.Length - 1
v = v + Val(Mid(Bits, i + 1, 1)) * 2 ^ (7 - i)
Next
Dim result As String
result = Format(v, "X2")
Return result
End Function
Shared Function EncodeUCS2(ByVal Content As String) As String
Dim i, j, v As Integer
Dim Result, t As String
For i = 1 To Content.Length
v = AscW(Mid(Content, i, 4))
t = Format(v, "X4")
Result += t
Next
Return Result
End Function
thanks in advance

Why don't you start yourself by going line by line? All what I see are only 'Dim' and 'For' statements you need to parse. In VB 'Dim' is to declare a variable.

What do you really need to do?
Might be easier coding directly your C++ functions (i.e. based just on requirements) instead of mimic the ugly VB.

Conceptually you should not try to do this. If you want to create a button in WIN32 application you should see the CreateWindow API

CButton is a MFC class, so you can't use it in a Win32 without MFC. You will need to create a MFC project if you want to use it.
|
|

|

You shouldn't.
In other words, you need MFC in order to use a CButton, but, do you really want to bloat with MFC your neat Win32 application just for using CButton? You may use plain Win32 API function for dealing with buttons.

hi friends,
i have have a MDI Application. when i close a document using onclosedocument. my document handle remains active though the members used in document are set to null. so i cannot check this condition
if(doc)
as it returns true. whereas in the if block it cannot access the members so app crashes
eg.
<pre>
if(doc) //handle =FAEX000
{
doc->getprivatevariable_or_functions(); // the application crashes here
}
</pre>
thanking in anticipation

How did you allocated the "document" ? I mean how did you create the pointer doc (it seems it is a pointer, right?).
When you release your document (for instance by deleting the memory), you also always have to assign null to it, so that you can check whether it has been deallocated. If you do that, then your code will work properly (the if segment won't be entered since doc is NULL).

You may override CDocument::OnCloseDocument for marking your document as invalid (you may set a custom property for the purpose) and then check for document validity before any access.

Thanks For reply Sir.. but prob still not resolved

Hello everyone, I have recently joined so I am a newbie. I only have taken one C++ course but am mostly self-taught by you wonderful people in the forums. I used forums to teach myself VBE so now I am using them to get better at C++. Just to be clear, my programming can be akin to a caveman putting a square peg in a round hole, i.e. it won't be pretty but eventually it will get there.
Question I have is, with the following code I kind of expected a zero value to be passed to x when the else part and the if-else was triggered, but it returns an abnormally huge value. This is a .dll being called from VBE.
Please forgive me if I have posted wrong, it is my first post.

double p = (arg * 0.0068947572); //convert psia to MPa
double beta = pow(p,0.25);
if(p >= 0.000611657 && p <= 22.06495)

First, if it's returning a large value, then my suggestion as that 'p' is between 0.000611657 && 22.06495.
On the other hand, how do you know that x was assigned '0'?
Second, for programming clarity, may I suggest one of the following: (my preference is #2)
1. getting rid of the two returns and have only one return after the closing brace ({) of the else,
if (a)
{
...
b = 1
}
else
{
b = 2
}
return b;
2. OR, remove the else
if (a)
{
b = 1;
return b;
}
b = 2;
return b;

Thank you for your reply. Actually what the code computes is the steam saturation temperature given pressure. The abnormally large value comes in when the p is not between the 0.000611657 and 22.06495. I had no luck with your modification, I am assumin it is in the syntax but have had no luck thus far.

you posted
if(p >= 0.000611657 && p <= 22.06495)
which fixed up reads:
if(p >= 0.000611657 && p <= 22.06495)
so that means p would be between 0.000611657 && 22.06495
if you want p to be outside that range, then change it to read
if(p < 0.000611657 || p > 22.06495)

I may not be clear on the code. p must be between these ranges for the calculation to execute, if it is outside of these ranges then the calculation does not apply and I want a 0 or a -1 returned.
