Hi, I was wondering on how difficult it is to convert a working in-process COM component (a dll) to an out of process COM component (an executable). The reason I am asking this is because I would like to move a dll to 64-bit while having the client in 32-bit. Due to the different architecture, they cannot run in the same process, so the only way to to this that I can think of is to have the server run as an out-of-process component. Any ideas? TIA.

Are you using ATL?

I am actually using MFC, I would like to convert the COM component created in this tutorial:
http://www.codeproject.com/com/COM_from_scratch_1.asp?target=COM%7Cscratch
to an out of process COM component.
Thanks!

COM will let you run your in-proc server in a surrogate process. Try using dllhost.exe.
To do this, you can change your components settings by going into the OLE/COM Object Viewer. Select All Objects; Find your Component; Select the Implementation Tab and then check the "Use Surrogate Process" check box.

Thanks, I have looked into it and it makes sense. I have also looked into the 64-bit SDK documentation and found the following:
"...On 64-bit Windows, an out-of-process 32-bit COM server can communicate with a 64-bit client, and an out-of-process 64-bit COM server can communicate with a 32-bit client. Therefore, if you have a 32-bit DLL that is not COM-aware, you can wrap it in an out-of-process COM server and use COM to marshal calls to and from a 64-bit process..."
So if I use a native 64-bit dllhost.exe as a surrogate process for my native 64-bit dll component and call use it from a 32-bit exe, it will be running as an out-of-proc? Thanks for the help.

Hi,
Please can someone help me. I have designed an App in MFC on Windows 2000. There are a lot of dialogs in this application which are 'skinned' (in the resource editor) by images I have created in photoshop. I am trying to transfer the code to Windows XP and have found that the dialogs I have created have increased in size. This is a problem as all of the controls on the dialog are misplaced compared with the bitmap underneath. Does anyone know why this is?
Any help would be grealy appreciated?
Thanks in Advance ,
Richard

When you use a skinned window, you should usually turn off themes for your window, so the physical dimensions are the same as previous versions of windows.
SetWindowTheme ( hwndYourWindow, L"", L"" );

I've finally reached my limit on adware and tracking software, to that point that there's so much protection software now running on my development system that it's getting hard to get real work done.
The last straw was SpamNET; a P2P email anti-spam application that seemed to be the best thing since sliced bread, until I realized they're accessing Internet Explorers Cookie and History index files and uploading that data.
I want a utility or good pointer to info that will allow me to restrict access to particular files on a per-process basis (e.g. only allow IEXPLORE.EXE access to ..\Content.IE5\index.dat).
I'm familiar with process wide hooking and filter drivers, but would like this to have minimal impact on the system and don't want to start from scratch unless absolutly necessary. What's the best way?
Thanks In Advance!

I've used a method that DavidCrow gave me to iterate through all the messages in a user's inbox. That works fine. But the _MailItem object has functions for GetSenderName, which returns the name (John Doe), and also the subject, body and HTMLBody. But I can't get the sender's email address. Any help on how I may be able to do that? Thanks in advance
If it's broken, I probably did it

Hi
My company is looking for a visual c++ (MFC) programmer to freelance on a few small apps we need writing.
We have written a few simple apps before but just don't have the time anymore so would rather call in an expert.
Serial and IP experience required. Experience with graphics and bitmaps a must.

Get in contact if you think you may be able to help.
Best regards

Hello..
I'm reading a book that describes how I can use build in wizards in Visual Studio 6.0 to add message handlers. It tells me to right click the class, and click add windows message handler.. But i'm using VC7.0.. Where can I find this functionallity? Specifically I want to add an OnCreate handler.
|

A message handler is just another function.
In your header file add this declaration:
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
In your implementation file where it says,
BEGIN_MESSAGE_MAP(CYourWindow, CWnd)
this is where you tell it what method is going to handle which message.
Add this ON_WM_CREATE() somewhere in the MESSAGE_MAP.
Then add your function to the implementation file like this:
int CYourWindow::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
}
BTW, I'm assuming MFC is used. Otherwise you'll have this huge switch statement to modify.

Yes, but I was getting tierd of writing code like that and wanted the wizard to do it for me. I just can't seem to find the "Add Message Handler"-wizard in VC 7.0.

If its in a dialog, you can right click on the control.

But it's not. My book tells me to "Right-click CMainFrame in the ClassView window, select Add Windows Message Handler, double-click WM_CREATE, and click Edit Existing. You'll find yourself in the empty message handler body, poised to type in the finished code. ClassWizard has already done everything else, including adding an ON_WM_CREATE entry to the message map."
But there's no "add windows message handler" in VC 7.0(at least I can't spot it)

You can also go to class view, click on the class, right-click and go to properties. Then click on the messages button and add your handler.

In MFC (VC6.0) how do I remove a start-menu folder?
I can delete all of the items, but however I try to delete the folder (_rmdir, SHFileOperation) I get a permission denied error.
Any suggestions? It looks like the shell keeps a lock on the folder.

I'm curious why you'd want to remove the Start Menu folder. Trying it yields a "Start Menu is a Windows system folder and is required for Windows to run properly. It cannot be deleted." message.

Bad wording on my part. A menu ON the start menu. We have an application that re-installed itself somewhere different during an update leaving people with a bad shortcut on the start menu.
I've worked out a program to delete all of the .lnk files pointing to the old directory, but was having trouble deleting the directory.
Since my original post I've realized that the problem was that I was trying to remove the directory while a FindFile was still pending on the directory. Once I moved the delete routine to another part of the program all worked fine.
Thanks

How can I change the language at run-time. I use resource-only dll's for the different languages and set it in the MFC method CWinApp::InitInstance with AfxSetResourceHandle before the MainFrame is loaded. How can I do this, when the MainFrame is already loaded. What do I have to do besides the AfxSetResourceHandle, that even the Menu and all the dialogs are now in the new language? Thanks for any help.
