Problem Opening Email when using InvokeHelper in C++
-
Hi I have an MFC Project, and what this project does is to allow a user to Open an in a number of different way, either a new email message, a new email message using a template or open an existing email message. The MFC is part of a much larger application and some of the data for selecting the correct email templates and opening an existing email comes from a web service. My MFC Project works to a certain, I can get Outlook, I can get my Web Service with my email template, but when I reach the point of Open the Email either a new one, open or otherwise it fails. Here is my code snippet: CString emailPath; LPDISPATCH mailItem; static BYTE params [] = VIS_BSTR VTS_VARIANT ; m_outlook->(0x10a, DISPATCH_METHOD, VT_DISPATCH, (void*)&mailItem, params, emailPath, NULL) //falls over here! outlookMailItem = new COleDispatchDriver(mailItem); What I have done wrong? Thanks

Who falls over, the programmer or the user? If you want a serious answer then try posting a serious question. Explain what actually happens in your program:
- do you receive an error response, and if so what is its value
- do you get an exception, and if so ...
- does your program cause a system error, and if so ...
- ...
I trust you get the idea.

The Code is running in TstCon.Exe as attached process in VS2010 with break points at certain points. The exception is thrown by Outlook 2003. If I leave the parameters as they are, I get a Message box showing an Unhandled Exception with a lot of Hex Numbers in VS2010. If I change some of the parameters, to the ones shown below: static BYTE params [] = VTS_I4 ; InvokeHelper(0x10b //Everything else as before Then I see the exception thrown as Outlook Error in the GUI of TstCon.Exe not in VS2010 on a breakpoint. There are two errors I get depending upon the value I have for the first parameter (either 0x10a or 0x10b) and keeping the params as VTS_I4 - one says "Unable to Open file xxxx [xxxx being a number]. Check the permissions or check to see the file exists." or "Could not complete the operation. One or more parameter values are not valid". It is the program that is causing the error, which is rooted with one of the parameters not being correct, or needing a different parameter to open the open the email.

Both of these errors seem quite clear as to the problem, so you need to check your parameters against what is required in the MSDN documentation.

Hi Thanks for replying & for helping me! Would you mind giving me a steer where in MSDN massive library where I can find a list of all the parameters that is expected when opening an email with a template? Thanks

Just go to MSDN and use the search box for the function that you are trying to use.

Thanks I will have ago to see if I can find what I need, but do you mind if I can call on your help if I get stuck?

what object is
m_outlookand what method is0x10a? I don't think your problem is with invokeHelper, I think it's with the underlying method in the m_outlook objectHi The code is based upon this website: http://repositorium.googlecode.com/svn/trunk/AbstractSpoon/OutlookImpExp/Source/msoutl.cpp Yes, there is a mistake it should say m_outlook->invokehelper and m_outlook is the name for outlook object which I have called before to start MS Outlook. The next step is to open an email template that is given a template file path and to display this to the user. I have tried searching MSDN for help, but I can't find any help. The code I have used is based upon this from the website above: LPDISPATCH _Application::CreateItemFromTemplate(LPCTSTR TemplatePath, const VARIANT& InFolder) { LPDISPATCH result; static BYTE parms[] = VTS_BSTR VTS_VARIANT; InvokeHelper(0x10b, DISPATCH_METHOD, VT_DISPATCH, (void*)&result, parms, TemplatePath, &InFolder); return result; } I have tried passing in NULL for the last parameter as there is no folder involved, but I am guessing on a lot of this because I have no idea what the exact definition of the method in MS Outlook for 0x10a or 0x10b. As I have said I can't find in MSDN any definition for this. Can you help?

Looking at the type Library for Microsoft Outlook ...

Thanks for your email. I had a look at the link you gave me from MSDN. However, I am still just as confused and still stuck. The code I have been given is that in my original posting. I have an Outlook object, because this code is not falling over, but I can create a mail item for a template.

in your original code snippet, you're using a
CString, you need to use aBSTRuse theAllocSysString()method inCStringthat may helpOk, so are you saying I need to convert CString to BSTR and AllocSysString() to do this?

What am I doing wrong?

I believe your problem is with the last parameter to "CreateItemFromTemplate". NULL is not the correct way to pass an [in, optional] VARIANT. There is no need to convert filePath to a BSTR, presuming that "outlookApp" is indeed an COleDispatchDriver. Do cast it to an LPCTSTR, InvokeHelper expects an in param defined as a VTS_BSTR to be an LPCTSTR, MFC's implementation of COleDispathDrvier will do the BSTR conversion for you inside the InvokeHelper call.
OpenOutlookNewMessageWithMsgFile(CString filePath)
{
COleVariant varOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);
LPDISPATCH mailItem;
static BYTE params [] = VTS_BSTR VTS_VARIANT ;outlookApp->InvokeHelper(0x10b, DISPATCH\_METHOD, VT\_DISPATCH, (void\*)&mailItem, params, (LPCTSTR)filePath, &varOptional); -

Because I do not have a folder for the email to be created in and wish to use the default folder inside Outlook, what parameter should I use, or should I only pass in the parameters I am using and Outlook can then interpret this?
