Hi Mark,
Why do you make such conclusion? More details?

One of the fundamental reasons for COM is interoperability regardless of platform or language.
If some other app requires a certain platform it doesn't sound like COM to me.

Excel 2003 is entirely native. Don't know about 2007, though.

Thanks Nemanja,
Do you know whether there are any support document (official)?

Get a copy of Dependency Walker[^] and then have a look at all the DLL's it pulls up. I know for sure that Excel 2003 doesn't require .Net.

Hi Jim,
I have installed this tool and use File --> Open to open Microsoft Excel, and on the left side, there is a tree hierarchy describing the dependencies of DLLs.
Do you know how to make conclusion of whether Excel is dependent on any .Net Runtime Framework from the output of DLL dependencies of dependency walker?
regards,
George

Hi There,
Myself Abhijit and need some input from your side about DEVCON. I hope you will help me in this regard.
I am working on module in which USB drive needs to be ENABLED or DIABLED through command line argument ON or OFF.
Initially I achieved it by changing registry values for USBSTOR and imagepath location. But as REBOOTING of system is required, I used devcon.exe to enable or disable USB drive. I used command
Devcon disable USBSTOR\DISK* to Disable USB and devcon enable USBSTOR\DISK* to enable USB. Devcon.exe was placed in my code folder.
Now problem is I want to remove devcon dependency and use devcon's code in my application for enabling or disabling USB drive.
I am not getting which functions to used for the same and how?
Do you have any idea or sample code in this regard with you so that i can proceed further.
I am getting lot of compilations errors when I include devcon.h and use functions from devcon.cpp like enumeratedevices and so on.
Can you please help me in this regard as this is very urgent for me? I do not have any prior knowledge about devcon.
Hoping a positive reply from your side.
Best Regards,
Abhijit Kulkarni,

Devcon is the sample code for showing how to do this. First, get devcon itself to compile then step through in the debugger to trace how it performs the commands you want. Once you understand all the steps that devcon goes through, then and only then start putting the required functions into your code. You really need to do the first step if you want to understand how enables and disables work. You're getting into the realm where you really need to understand what is being done and why. If you can't figure it out by looking at and stepping through devcon's source, you really shouldn't be trying to do it. I don't mean to preach (well, yes I do), but you're trying to work at a level where you've got spend the time to learn it yourself and be able to figure out for yourself what a working sample does if you hope to proceed.

Thanks Judy for the quick response.
I am doing exactly the same at present what you have mentioned in the reply.
Thanks again..

I apologize if I sounded harsh. I've seen too many folks start playing around with hardware and then massively mess up a system because they didn't truly understand what they were doing. I just wanted to save you from going down that road.
Also, you didn't mention what type of USB device you're looking to enable / disable. Especially if it is a mass storage device, you'll need to deal with the case where some program is accessing the storage when you want to disable it. The OS will let you disable it and then send errors to the programs. It's safe to do with respect to system integrity, but not very user-friendly.

Hi Judy,
I will take care of it. Thanks for information.
I am dealing with mass storage device.
I will get back to you with the updates once I finished the same.

Hi
I want to ask a question which is very important for me.
My project is on Windows CE but the problem is about visual C++.I have a worker thread that is waiting for the data coming from serial port.I want that when a definite data is comes I want to change the focus on controls.I am doing that with;
if(the definite data comes)<br />
dlg->PostMessage(WM_NEXTDLGCTL,NULL,NULL);
dlg is the object of the dialog box which I want to change the focus.But that is working only for the dialog box which the thread is working in.I cannot change the focus of controls for dialog boxes other then the dialog box which has the thread.
If I can explain the problem can you help me.
Thanks

Two considerations:
1. Only one window can have the focus at a time.
2. It is indeed possible to give the focus to a dialog which is not used to start a thread. This a design problem.
Post the code where :
a. you create the thread
b. you want the dlg to be updated.

So why are you not calling SetFocus() for the control you want to have focus?

Are you really passing NULL for the WPARAM/LPARAM parameters when posting the WM_NEXTDLGCTL message?
That sets the focus to the next control in the dialog that has the WS_TABSTOP style. Is that what you want or
do you want the focus on a certain control?

The problem you're probably running into is that you're making message calls to an HWND created in thread A from code that is executing in thread B. To make things work correctly, you to to make sure that the code executes on thread A (or whatever the correct thread ultimately is). What you can do is have your worker thread (the thread(s) that is spawned by the main UI thread) call PostThreadMessage, and use the thread ID of the main UI thread. The message will be some custom message specific to your app, and in that message handler, you can then do things to your UI/dialog box.
You should read up on multiple threads and windows, and the PostThreadMessage/GetCurrentThreadId API's.

I have VC++ project. In this project I have included Max plugins which are developed using Max4.0. Now I have to configure this project to Max 7.0. What are the changes do I have to make in the configuration manager?

Hi,
No one can help you because they don't know what you're referring to.
What is Max? What are max plug-ins? Are they using (written in) plain old C++? COM? .Net? Something else?
