Hi again,

I have a VB6 application using EASendMail, compiled it and run smoothly on my machine. Now when I tried to copy the compiled file (*.exe) to a different machine and run it. It gives the Error 429 - ActiveX can't create object. I found out that EASendMail.exe needs to be installed in the local machine and the error disappears. Is there any workaround on this so that we don't need to install the EASendMail.exe on every local machine that runs the application?

Thanks!

New solution is:


Registration-free COM with Manifest File

Registration-free COM is a mechanism available on the Microsoft Windows XP (SP2 for .NET-based components) and Microsoft Windows Server 2003 platforms. As the name suggests, the mechanism enables easy (for example, using XCOPY) deployment of COM components to a machine without the need to register them.

With Registration-free COM, you don't have to use "regsvr32" to register the dll as COM object, you also don't need to worry other version of this COM installed on the same machine overwrite your current version.

We strongly recommend that you use Registration-free COM to distribute EASendMail ActiveX Object with your standard exe application. ASP, VBScript or other script application is not suitable with this feature.

Using Manifest File

For standard exe application, you just need to create a manifest file like this: Open notepad or other text editor, copy/paste the following content to the editor.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <file name="EASendMailObj.dll" hashalg="SHA1">

    <typelib tlbid="{8B5A2BD0-5638-4CCA-A7FF-91B9E6768AC4}" version="1.0" helpdir="" flags="HASDISKIMAGE"></typelib>
  </file>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>

  </trustInfo>
  <comInterfaceExternalProxyStub name="IMail" iid="{1AD28FC9-0C71-4E89-85C9-CAECDE8BE3AB}"

</assembly>
    

Then save it as yourappname.exe.manifest. For example, your application exe file is: myproject1.exe, then save it as myproject1.exe.manifest.

Finally, copy myproject1.exe, myproject1.exe.manifest and EASendMailObj.dll to the same folder on target machine, your application can use EASendMail ActiveX Object directly without COM-registration.

Hi, I guess clsSendMail is a control wrapped EASendMail in your application, if you built it as ActiveX Control, you should also regsvr32 yourcontroll.ocx on target machine.
