WD-22 32 bit Windev app and Outlook 64 bit

Hi Friends,

Is there any solution to use 64bit Outlook in my 32bit application?

I tried to convert my 32 bit app to 64 and i am getting lot of technical errors.

I am using Windev function "OutlookStartSession" to access Outlook.

Thanks in Advance

Hi, it depends on the operating system of the computer. There is no way to run a 64-bit application on a 32-bit OS. There should be no problem to launch a 64-bit app on a 64-bit OS.

Hi Guenter,

I am able to run my 32 bit WinDev application on Windows 64 bit without any issue. Only problem when access Outlook 64bit from my WinDev 32 bit application.

Also Outlook 32bit working fine with my Application.

My problem is "OutlookStartSession" gives error when i am having Outlook 64 bit.

Hi @ all,

I had the same issue here, and solved it like that:

I distribute two additional EXE with my appplication, they are called callMapi32 and callMapi64 and are compiled in 32 or 64 bit

If I want to send an e-Mail using emailRunapp (and it should also work with outlook) I do following:

The main app creates a XML File containing all information I need to send the mail (to Adress, Subject, Body, path to attachments) and stores this XML in the temp directory.
Then I call either the 32bit or 64bit exe (depending on the OS) and pass the path to the xml as parameter to this 32 or 64 bit exe.
This exe then reads the XML and executes "emailrunapp()".

Works fine for month, only problem there is a litlle delay in opening the mail program.

If you want, I can share the code.

Stefan.

Hi Stefan,

Thanks for the reply. I understood the logic, if you can share the code it will be very useful.

In my case I will still have issue as I am also using outlook calendar in my application.

Thanks & Regards

I have had this issue for the past year now. Been extremely frustrating to have 2 versions of the software and having to check if outlook is 32/64 bit.

Finally I have a solution. You use EmailBuildSource() and use the MyMessage is Email variable..build the .eml file and then then use ShellExecute() to open the .eml file

Works great! (WINDEV)
