Trying to launch e-mail client Outlook with arguments

[tvnaidu]

when I try from command prompt "Outlook.exe /a test1.jpg" (I copied test1.jpg file into same folder where outlook.exe exists, outlook client opens with test1.jpg as attachment with new email, if I try samething with CreateProcess in C++, it is not working, any wrong with my command below.

                if (!CreateProcess(L"C:\\Program Files\\Microsoft Office\\Office14\\OUTLOOK.EXE", 
                            L"/a \"test1.jpg\"", 
                            NULL,
                            NULL,
                            FALSE,
                            0,
                            NULL,
                            NULL,
                            &si,
                            &pi))
                {
                        return false;
                }

Check your arguments.

The first argument is a LPCTSTR. This is long pointer to a constant TCHAR string. You have supplied a string of wide characters. Generally, you neeed to make these Unicode strings using MultiByteToWideChar.

Similarly, the second argument is a LPTSTR which is a long pointer to a TCHAR string. You have supplied a string of wide characters and it looks like you have some undoubled \. Again, MultiByteToWideChar needs to called to make this string.

The last arguments are long pointers to a STARTUPINFO and a PPROCESS_INFORMATION struct. Your posted code doesn't show if these are valid or not.

You may need to read up on TCHAR. But I don't know your runtime requirements. If they are Unicode, then you need to create all of your Unicode strings correctly and there can be no literals in your code.

BTW I have found no examples to let you start Outlook from C or C++. There are several in C# and they are no simple.

Let me know what happens.

This is running on Windows XP and Win 7 environment, I like to run "Outlook.exe" with arguments, basically I am launching Outlook email client, when it launches I need jpg file as attachment. The other Two declared as:

STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
ZeroMemory(&pi, sizeof(pi));

OK. But what is your project environment? char or Unicode or both? This setting is in your project properties.

CreateProcess is either a call to CreateProcessA or CreateProcessW based on the run time envionment. This is where TCHAR comes in.



if char, a string like L"stuff" is not a char string. In a char environment CreateProcessA can't use it.
if Unicode, a string like L"stuff" is not a Unicode string. CreateProcessW can use this only if language is English.

I woud be using TCHAR or I would be calling CreateProcessW.

You should read this http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx
and pay close attention to the community input.

I did look into Project Prop, it says "Use Unicode character set". when I keep cursor on CreateProcess , it says "CreateProcessW".

actually I gave file name test1.jpg as testing purpose since by command line I am able to attach jpg file when I launch outlook email client, but I have actual Image is loaded on Clipboard inside my program, I like to attach that Clipboard Image as attachment when I launch OUTLOOK.exe, Is there any Windows API where I can store clipboard Image as file and attach that file to outlook on the background without any input from user.
