How do you do this sort of thing?
I have two projects in mind.
1) write a better xfer program for my MP3 player than the one supplied with it
2) talk to devices of my own design via the USB
What I would like to know is how does one go about chatting to a device on the USB port.
Are there any utilities that can monitor the data that is transferred on the USB?
I want to know what the xfer program sends and recieves from the MP3 player.

This would be advanced stuff. The USB driver itself is a kernel mode driver.
To monitor operations you would probably have to write an upper level filter driver on top of the functional driver supplied for your MP3. This may exist somewhere, dunno.
Just thought I'd share my own frustration with the whole API with someone

Hi,
I have a problem using msmask32.ocx and msflxgrid.ocx.
I'm using it in an application under VC++ 6, which has an editbox using mask. But to get or set the text of the edit, an error occurs.
If someone can help, please.
Thanks.

Hi,
When I try to connect to a remote computer with WMI between WinXP German edition and WinXP English it always returns "access is denied", between two english WinXP or two German WinXP computers it connects without problems. Does anyone know what's the problem ?, is it a bug in WinXP/WMI ? or I am doing something wrong?
Thanks!
Best Regards,
Mario M.

MD5 is for producing a hash (or checksum). It does not do encryption/decryption.

Hi all, I'm hoping that someone knows how to specify a frame that is always active in an mdi app? I want it so that even if a child window is activated, the other frame (linked to different document type) is not deactivated (so that the title bar does not change colour from dark blue to light blue)? Any ideas would be well appreciated. At the moment I create my frames indirectly through a document template if that helps.
Many Thanks,
Alan.

I believe that only one MDI child can be active at a time. If you want a frame window that's always active create it with the desktop as parent window. Dont make it a child of the MDI frame. Even then though it will be on top and visible, it wont be active if some other window is active.
Nish
p.s. Under normal Windows OS rules only one window will be active.

Yeah thats the thing, I've been at this for ages and can't get it to go. I've managed to create a frame thats on top, does everything I want, except stay active. I am sure this can be done (somehow) cos if you look at VC++ you can detach the workspace pane into a tool window which remains active despite an mdi child window (a .cpp or .h file) being active. Try it out, that is exactly what I want it to do. If it gives you any further ideas give us a shout. Thanks for looking at my problem though nish, much appreciated.
Many Thanks,
Alan.

Well, when you un-dock some of the VS windows, they do appear with a blue title bar, but this does not mean they are active windows. I believe they custom-draw their title bars somehow. I am not very sure about this though.

Maybe creating each frame on a different UI thread? This poses all sorts of deadlock problems, however.

Well, I've finally done it. All you have to do is override the OnActivate() function in the CFrameWnd class and have it pass true to MFC's activation function so that :
CFrameWnd::OnActivate(true, this, 0)
As soon as I did this it worked no problems, just thought I'd let you guys know and say thanks for your ideas and responses.
Many Thanks,
Alan.

I am surprised that worked
The first argument is actually a state which can be one of WA_INACTIVE, WA_ACTIVE or WA_CLICKACTIVE.
And you have passed true.
Anyway good for you
Nish
p.s. By the way this only stops them from going un-blue. The fact that only one window will be focally active remains.

Using ImageMagick (www.imagemagick.org), I now want not only to load, convert and store images, but also display them in an Windows window (i.e. its Device Context DC).
On the page http://www.simplesystems.org/ImageMagick/Integration/ there are two packages (WinExt and DisplayUsingCDib2) mentioned. But the first is using an outdated version of ImageMagick and the second link is dead.
Question: has anyone successfully tried to display an ImageMagick image inside a Windows window and can contribute a small code-snippet or even a complete function like e.g.
void DrawImageToDC( Magick::Image src, HDC dst_dc )

I believe from memory we did it by creating a DIBSection and using memcpy to copy the bits into it. Then we drew that.

I've even downloaded the Microsoft Vision SDK and currently looking into the HUGE code sections. Maybe I'll find there some code.
Can you provide some code of how you did it?

I'm sorry, I am more than 1,000 klm away from the code that did it
Do you have access to the image byte array through Image Magik ? If so, look at my code at www.wdj.com in the Sept 2001 section. It shows how to create a DIBSection and get access to the location of the byte array.

I have a vector of POINTs and I want to draw a curve that undergo(pass over) all that points in my vector. Somebody adviced me to use Bezier...and probably he is right. But using Bezier method the curve bypasses several points in my vector(control points) which is not my purpose.I hope i make myself understood. My knowledge regarding Bezier curves is so weak that I need your help.
Thank you in advance..I promise to rate good answers.

*grin* CP ( thankfully ) has no rating system.
Beziers are mapped by specifying control points, but the curve does not pass through those points, it's more like a magnet, pulling the line *twoard* that point, not through it. I can't recall off the top of my head ( no MSDN or books here ) how to draw a line that passes through the points, but I know there is an AngleArc function, or similar, which may help you.

Hi!
I want to make a DNS on may computer (e.g. chat1.suza.com) so my client apps don't have to write in the IP every time they want to connect to the server. This is just over LAN.
Do you know how ??
