Hi,
I am looking for some neat code to process HTTP Post request content data - i.e. tidy up all those '+'s and '%'s, and split the POST content string into variable name / variable value pairs. I could try this myself, but I do hate reinventing wheels ... can anyone suggest some code to do this ?
Thanks,
Neil Humphreys.

Thanks for the reply.
Your article is a web client, which writes POST requests (presumably). However, I am after web server code, which reads POST requests.
Thanks,
Neil Humphreys.

Sorry, I should have ready your post more closely before replying. Meanwhile, will this[^] collection of classes help?

VC++.net : I have a problem, maybe someone can help me.
I try tu make a DLL to use with a client (Cocreate ME10).
I created a Regular DLL with MFC statically linked.
Then i created a CDialog with a CComboBox and a CListbox what i like
to fill with Items from a Database.
In the CDialog Class i created a Control variabel to the CCombobox:
CComboBox m_ctlCbNames;
To make work my modeless Dialog i use :
BOOL WINAPI FilterDllMsg(LPMSG lpMsg)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
TRY
{
return AfxGetThread()->PreTranslateMessage(lpMsg);
}
END_TRY
return FALSE;
}
If i load the DLL in my Client application the Dialog appears without
any Problems.
But if i try to add a string to the Combobox control variabel :
m_ctlCbNames.AddString(_T("Test"));
or
m_ctlCbNames.SetCurSel(0);
then i get the following Error when i call my function in the DLL from
my client program :
Debug Assertion Failed !

I made a very nice duplicate file finding utility for myself a few months ago.
Now I just wanna share it with you guys (altough I am not very sure who would ever require such a tool ! Anyone ?)
However, I just want to add some more features to the basic framework.
The basic engine just creates a hash table of filenames which are kind of open chained using linked list of filenames which have the same MD5/SHA/etc digest (that is, are binary equal)
It currently finds out any duplicate file(s) in/on your directory/drive and deletes all but the file with the most recent timestamp.
That's all I wanted, but I understand that it's the least somebody who seriously wants to use such tool would want !
So please, let me know who might want it, and what feature(s) should I add to it....
Given enough takers, I might write up a nice article to go along with the source code.
In the meanwhile, keep the feature requests rolling in...

Hello Freinds,
I want to transfere one structure from client to server. structure contains one String and INT data, INT is the length of that string.
I am trying send(); function of CSocket to transfere the structure but I am getting some garbage at server end and missing my strings address.
Can anyone pl's help me.
I have dought that the function I am using may not be currect.
Thanks.
Dinesh.

why don't you directly transfered the string to the server!,as recv winsock api returnd with total length of data recieved.
something like this way, i am giving win32 based code
Client End:
char szString="Codeproject";
UINT nszLen=strlen(szString)+1;
send(hSendingSocket,szString,nszLen,0);
Server End
char szString[1024];
int nTotalBufferLen=1023;
int nRecv=recv(hRecvingSocket,szString,nTotalBufferLen,0);
szString[nRecv]=NULL;

Dinesh, I recommend using CSocketFile and CArchive. They work beautifully!

Hi friend,
Maybe the problem is that, if you are using TCP/IP protocol, the structure is divided as multiple packets on the network, so you should first send the size of the structure (string + int), then use recv() and check that the number of bytes received are equal to the size of the structure before using the structure, or USE UDP/IP.
something like this:
<br />
int nRecv=0;<br />
<br />
while(nRecv<SizeOfExpectedData)<br />
nRecv+=recv(....);
//now i am sure i received the whole message, not just few packets
//now use the structure

Hi All,
Has anyone of u developed a class which can Transfer a File across LAN.
I have a client Server Application which can Send and Receive messages between them. Now i want to implement the File Transfer.
Looking forward to ur valuable Suggestions..
Thanks.

Hi
have you tried to use the API function defined in Winsock2.h:
BOOL TransmitFile( <br />
SOCKET hSocket,
HANDLE hFile,
DWORD nNumberOfBytesToWrite,
DWORD nNumberOfBytesPerSend,
LPOVERLAPPED lpOverlapped,
LPTRANSMIT_FILE_BUFFERS lpTransmitBuffers,
DWORD dwFlags <br />
);
it will work faster than any implemented function or class, because it works in kernel mode rather than user mode.
Regards,
Mohammad Gdeisat

hi,
I really have not used this function, but as a sense, i think that the other end should use recv() with a connected socket on appropriate IP and port number.
anyway, this is all i know about it. you can still search for examples on TransmitFile

Hello there,
I'm using Visual C++ 6 with Platform SDK and trying to create a imaging program. The program is simple, where i the user can draw lines on a TIFF image.
I'm using GDI+ for this purpose, but having one problem. The problem is that GDI+ just cannot draw on gray(8-bit)/black & white TIFF images or BMP for that matter. I dont know why. A simple test code is given below,
void CGDIPlusDlg::OnButton8() <br />
{<br />
CDC *pDC=this->GetDC();<br />
HDC hdc=pDC->GetSafeHdc();<br />
<br />
Image img(L"c:\\mspaint.tif");<br />
RectF r(0, 0, 100, 100);<br />
<br />
Graphics gr(hdc);<br />
RectF destRect(0, 0, 100, 100);<br />
<br />
gr.DrawImage(&img,destRect);<br />
<br />
Pen blackPen(Color(255, 0, 0, 0), 3);<br />
<br />
PointF point1(0, 0);<br />
PointF point2(100.0f, 100.0f);<br />
<br />
Graphics gr2(&img);<br />
gr2.DrawLine(&blackPen,point1,point2);<br />
<br />
RectF destRect2(100, 0, 100, 100);<br />
gr.DrawImage(&img,destRect2);<br />
}
The image is created using MSPaint. Create a 100x100 image, draw something, and save as TIF. Save again by changing the image depth to black & white from the Image->Attributes menu.
The program supposed to draw a diagonal line across the image, but it doest for the black&white version of tif.
So, my problem is how to overcome this? Or, how can i programmatically convert a BW TIFF to color and work on it using GDI+?
Oh yeah, can anyone try if this code works fine in C# or managed C++?
Thanks,
Usman

I have inherited a class from CFileDialog.
OnTypeChange has been overridden with the purpose of changing the direcory when the user changes the filter list.
How do I actually change the current directory?

What is the event message when the user clicks the x in the system menu.
Background:
I have disabled OnCancel() and OnOK() so that in my dialog-based app the esc and return keys don't close the app.
I have the OnFileExit (when user selects file exit) method calling EndDialog(IDOK) directly. What function is called when the user clicks on the x?
Long and short of it is I dont want keyboard commands (other than alt navigation) to close the app.

Have you looked at OnClose()?

Yes. The problem is esc and return call OnOK and OnCancel, so doing anything to OnClose wont change anything.
I think the problem is that clicking the x calls OnCancel (or OnOK doesnt matter which for my purposes).
I need a way to differentiate between hitting the return key and the esc key from clicking the x or selecting file close.
I dont want to get into Virtual Keys right now. Im not at that stage in writing this application yet. I try to write applications in phases. It makes things much simpler when I add functionality in groups.
