I was trying to retrieve the body of a message using the code below but
It is always returning
MAPI-E-NOT-FOUND:

hr = m_pfldrInbox->OpenEntry(
m_pInbox[msgID].lpProps[0].Value.bin.cb,
(ENTRYID*)m_pInbox[msgID].lpProps[0].Value.bin.lpb,
NULL,
MAPI_MODIFY | MAPI_DEFERRED_ERRORS,
&ulObjType,
(LPUNKNOWN*)&lpMessage);
//MessageBox(0, L"Message Opened", L"", 0);
if (SUCCEEDED(hr))
{
SPropValue * rgMsgprops = NULL;
ULONG rgMsgTags[] = {1, PR_BODY};
ULONG cCount = 0;
// IStream* istream;
ULONG ulNumChars;
// hr = lpMessage->GetProps((LPSPropTagArray) rgMsgTags, MAPI_UNICODE,
&cCount, &rgMsgprops);

hr = HrGetOneProp(lpMessage,PR_BODY,&rgMsgprops);
if (hr == MAPI_E_NOT_ENOUGH_MEMORY)
{
MessageBox(0, L"Not enough memory", L"", 0);
hr = lpMessage->OpenProperty(
PR_BODY,
&IID_IStream,
STGM_READ,
NULL,
(LPUNKNOWN *) &lpStream);

do
{
lpStream->Read(
sBuffer,
255,
&ulNumChars);
// if (ulNumChars >0) printf("%.*s",ulNumChars,szBuf);
}
while (ulNumChars >= 255);

// printf("\n");

hr = S_OK;
}

else if (hr == MAPI_E_NOT_FOUND)
{
//This is not an error. Many messages do not have
bodies.
//printf("Message has no body!\n");
MessageBox(0, L"Message has no body", L"", 0);
hr = S_OK;
}
else
{

//MessageBox(0, "%d", rgMsgprops[0].Value.lpszA, 0);
int x = 0;
do
{
sBuffer[x] = rgMsgprops[0].Value.lpszW[x];
x++;
//MessageBox(0, (LPCWSTR)sBuffer, L"", 0);
//bufferlen = strlen(rgMsgprops[0].Value.lpszW);
}while (((int)rgMsgprops[0].Value.lpszW[x-1] != NULL) && (x <
255));
}
}

If you can tell what is the problem please help

I understand that. You did not indicate which of OpenEntry(), HrGetOneProp(), or OpenProperty() was returning that value.

It is the HrGetOneProp() that is always returning the property tag that I specified. I used the same fuction to retrieve the subject and sender information using PR_SUBJECT and PR_SENDER_NAME property tags and it works. It only fails to get the message body. That is when I use PR_BODY.

Does this or this help?

For the message that is failing, are you sure it has a body?

You should probably check out the HTML Help Workshop from Microsoft. This would be the standard tool used between about 2000-2004. I'm not sure if .NET came out with something different so I apologize if this is not the standard tool used by the masses anymore. I still code native and use the HTML Help Workshop for my released products. For what it's worth...

I've not done help in a very long time, but I seem to recall the need for a .hpj file, a .hm file, and a .rtf file. The Help Compiler will compile these into a .hlp file.

David,

i must agree that the Help Workshop documentation is not very clear when you don't know where to start for a .hlp file.

could you please point out some good tutorials/articles to create one's first compiled help file ?

Microsoft changed from the dedicated Help file format (generated from RTF using the Help Compiler, hpj file, etc) about the time of Visual Studio 6, I think. All Help is done using the HTML help system these days, I am told.

Having said that, I wrote a Help file a year or two back using the old methods (which I was familiar with), because it was easier than learning about the new HTML Help system.

As far as I remember, VS6 supported traditional HLP, but you could add support for HTML help.

You can use any text editor (even Notepad) to create an RTF file, but that is a real pain in the butt. I recommend that you ignore any reference that tells you to write stuff like " {\rtf1\ansi\deff0 " - you can do this and work with raw RTF but there is no need to!

One easy way to make RTF files is to use MS Word (or other common word processors) since "Save As" allows you to save files in RTF format.

In Word 2000, creating footnotes is done by Insert menu / Footnote. In the Footnote dialog box, select Custom Mark, and use the "#" (Context name), "$" (Topic name), "k" (keyword), etc as the marking symbol.

If you do a Google search for "authoring winhelp help", you should get a zillion references. For a start, look at the following:

I can't help you directly with C++ - I use C, a real man's programming language! But this code should work, anyway.

Here is an extract from my main window procedure, where I handle the messages:

LONG WINAPI MainWindowProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
  switch (message)
  {
    case WM_KEYDOWN:
      // Handles keyboard actions
      switch(wParam) // Gives the virtual-key code
      {
        case VK_F1: // F1 key = Help
          // WinHelp(hWndPrimary, "helpFileName.hlp", HELP_CONTENTS, 0);
          WinHelp(hWndPrimary, ".\\helpFileName.hlp", HELP_FINDER, 0);
          // HELP_CONTENTS and HELP_FINDER open Help in different ways.
          // Look in the MSDN Help to see what the difference is.
          break;

It would have been a lot quicker for you if you looked up WinHelp in the MSDN help, to see what parameters it takes. This way you had to wait 12 hours for an answer.

Anyway, my application opens multiple windows, and hWndPrimary is the Handle to the Primary (i.e. main) Window.

Please listen to my idea.

I created a client/server model in UDP. Now its a one-way thing. The server keeps "recvfrom" and the client keeps "sendto". its ok. but now I wanna make it Two-way.

In the server,shall I create another sock in a separate thread? that makes the "sendto" part.
And similarly , create another sock in client to make the "recvfrom" ??
Server ````````````````````` Client

<br />
   1.sender  ------------------->   1. Receiver.<br />
   2.Receiver <------------------   2. Sender.<br />

Is this a good design? or should I make it like...

<br />
   1.Sender/Receiver <------------------>   1.Receiver/Sender<br />

If you say , the latter is the right method, also tell me how'd I do that?

_unlink() doent work on default address style

Helo guys! I am working on a project where I have to get addresses from user interation and then get ahead wih my job. And the addresses I retrive are of the form:
d:\Somefolder\Somfile.something

And _unlink does not work on adresses of these kinds. I have to change it to something that looks like this:
D:\\Somefolder\\Somefile.something
Only then everything works fine.
Can somebody comment.
By the way I am using VS 2002
