I am ripping my hair out and there's not much left.
I need a Visual Studio 2008 geek to let me in on some info.
I must create a DLL with C++ and call it with VB.NET
I will eventually need to pass ints and strings in both directions with the client and server. [VB &VC]
Every example I can find (Google, MSDN local & online, codeproject.com, etc.) doesn't get it going.

Is it because I need "managed" code for the C++ DLL?
Is it because of the platform build CPU targets??

I am running Visual Studio 2008 on an AMD machine in Windows Vista 64 bit.

(if you want, email is in profile)
Thanks

Drasher:,

Once you've compiled your component into a DLL, all you need to do is add a reference to that DLL in your solution. Make sure the physical file is located in the "bin" folder if it's a website, or the "Resources" folder if it's an application. It shouldn't matter if the component was written in C#, VB.NET or C++. Once you've gotten that far, you need to use an "Import" reference in your VB.NET class if the original component was wrapped in a namespace, as such: Imports [YOURCOMPONENTNAMEHERE]. From there, you can call your component by its method names as you need. Make sure that the methods you've written in C++ are exposed to external classes (by utilizing the modifier public in the function declaration).

That's about as detailed as I can get without actually looking at your code.

I have a basic question.

I am buying a new computer on Saturday to replace this current POS computer. I have a few small files that I want to save before I do a System Restore and sell my computer(I can throw these on a CR-RW or something). The thing is that I have iTunes, and I want to transfer my music library to my new computer, but it is about 10GB worth of Music. How can I transfer my whole music library without shelling out alot of money for an external hard drive? Is there any way to compress the file(s) to fit on a CD-RW? If there is a way to do it, how do I go about doing it?

If you don't sell your old before getting the new one:

Option a:
Put both computers on a network (if you already have or can borrow a switch, hub or router; otherwise you might want to get a crossover cable) , share hard drive of the old one, copy data to the new one

Option b:
remove hard drive from the old PC and put into the new PC, copy files, put hard drive back

10GB is only 2 and a bit DVDs

Or a 16GB flash drive.
 
  2009-09-30 09:16:31 PM
Yeah, 16 GB flash drives aren't that expensive as long as you get them from somewhere other than, say, Best Buy...

Mike: Yeah, 16 GB flash drives aren't that expensive as long as you get them from somewhere other than, say, Best Buy...

Damn, you ain't kiddin'. I checked it out and I can get a flash drive for as cheap as $30, but Best Buy has them for almost $80.
 
  2009-09-30 09:57:29 PM
I think I figured it out. When you go into iTunes, you just export the library to the flash drive, right? Hopefully it's that simple.
 
  2009-09-30 11:00:31 PM
You can just go into your My Music folder and copy the entire iTunes directory.

But that can cause a messed up Library on the new PC, and you end up having to rebuild the library.

Isn't iTunes always bugging you to back up? Because you could backup to the flash drive from inside of itunes... I think
 
  2009-10-01 12:16:18 AM
KoshkaVShliapa - Thanks, but there are a number of missing details...
I got a partial solution by setting the properties of the C++ code (DLL) to "x86" and the VB code to "Any CPU" but that didn't fix it all... now the parms (passing strings back and forth) is whacked.
I would be happy to give you a copy of the code if you provide an email address.

Nope, iTunes never asks me to backup. I think I can just export my whole library to the flash drive. Someone correct me if I'm wrong. I think you're right. Copying the whole music folder has screwed it up before. I had like 3 of the same song in the library for some reason.
 
  2009-10-01 12:02:18 PM
If you don't mind losing all the metadata like rating (1-5 stars etc), number of times played, album art, etc, you can copy just the music and reimport it to a fresh iTunes later...

Otherwise, what I'd probably do is
a) copy the entire music folder onto the flash drive
AND
b) export the library (probably to an XML file)
That way, you can piece it back together one way or another...

DDR2 has gone way up in price. I bought 4GB (2x2) for $40 in April, and now the exact same kit is almost $80.

piaddic120: I have a basic question.

I am buying a new computer ... [iTunes] ... If there is a way to do it, how do I go about doing it?


Per export page at Apple (new window http://support.apple.com/kb/HT1751) a simple copy will work, but do read the article.

Similarly, import page at Apple (new window http://support.apple.com/kb/HT1451) appears to indicate that copying the stuff into the new location, tossing the .itl file and doing File->Library->Import on the xml will provide a complete restore.

The former explicitly mentions iTunes 9 in the body, the latter does not. Although I am in the midst of doing a complete export and import across platforms, I have not performed either operation.


Do not attempt while driving or operating equipment or machinery. Test in an inconspicuous area prior to use. Exercise caution until all side effects are known. May cause dizziness. If redness, rash, swelling, or data loss develop, discontinue use and consult a qualified professional.
 
  2009-10-04 01:59:06 PM
I copied iTunes directly from one computer to another using network drive, I just made sure I put every file (like the .itl and .xml files that hold the library index and meta-stuff) in the exact same location on the new computer as on the old. I installed iTunes first so it would create those files on the new machine, then overwrote them with the backups.

Hello everyone, I have a problem I'm hoping you can give me some advice on:

My grandfather is a photography nut, and recently bought a high-end digital SLR camera which uses Compact Flash (CF) cards. He has a 1080p LCD TV and wants to view the pictures he takes on it, but doesn't have a CF reader. I need to find a simple way to let him view his photos on the TV in all their hi-res goodness.

Difficulty: NO COMPUTERS. My grandparents know NOTHING about computers and are too old to learn. I know there are a number of solutions for this problem once computers get involved, but he just isn't able to go that route.

I figured there would be some stand-alone memory card reader with an HDMI-out someplace but I am having a very difficult time finding one. Some DVD players have card readers but I'm having trouble finding one that reads CF.

I'd like to find something less than $100 if possible.

Any help would be appreciated! Thanks!

Some DVD players have card readers but I'm having trouble finding one that reads CF.

Maybe there's something like a CF-to-USB or CF-to-WhateverThePlayerCanAlsoHandle thingee?

Googleing CF to USB shows some results for thingees that seem to convert them into USB mass storage devices; so if there's a DVD player or one of those multimedia boxes that can read from USB devices..

If the camera also has an USB connector, you might be able to plug it into one of those multimedia boxes directly; at least
this review of a WD thingee claims:
It's a little black box that plugs into your TV and can be used to play audio and video, or view images straight from your USB storage devices (i.e. portable hard drives, or USB thumb drives).
[..]
if a friend is coming over and they want to show you some holiday snaps or a home video they can just bring a USB stick or even plug their camcorder/camera straight into the WD TV and switch it to mass storage mode. The WD TV doesn't care what it's reading, so long as it's a mass storage USB device, it'll give it a go.


Though if a box like this is more or less complicated to operate than a PC.. ;)
 
  2009-10-04 06:22:04 PM
Doesn't the camera itself have a video out on it? The dinky little point-and-shoot I just bought has an HDMI out on it... it'd surprise me if a higher end SLR didn't these days.
 
  2009-10-04 06:23:12 PM
Unless it was used with no accessories, the camera came with video out cable.

Also a good, modern DVD player should know what to do with a CD full of JPEGs.
 
  2009-10-04 06:37:11 PM
FuturePastNow: Also a good, modern DVD player should know what to do with a CD full of JPEGs.

I just looked in the manual for my four year old DVD player, and it has a page on making JPEG and MP3 CDs. Basic instructions like it won't auto-rotate pictures or display tags. If your grandparents have a decent DVD player it should do the same.

But your best bet for someone who can't figure out computers is to simply use the video cable the camera came with. The camera is a CF card reader.
 
  2009-10-05 02:14:17 AM
He said his camera doesn't have video out but there's a good chance he's mistaken so I'll have to check it out. I'll also check out the USB mass storage idea -> set top idea.

The CD/DVD with JPEGs is out; he'd have to burn them and that's beyond him to do himself and a hassle to have done for him regularly.
 
  2009-10-05 03:27:02 PM
On the set-top box idea, the non-slim Playstation3 will display photos off a CF card, though I bet you can find something a lot cheaper that does the same thing :)

I'm still betting that the camera's got some kinda output though. Canons definitely do. You didn't say what kind of camera it was though.
 
  2009-10-05 06:24:40 PM
Mike: Canons definitely do.

i218.photobucket.com

So do Nikons. You can see how much I use it. The newer ones should have component or HDMI.
 
  2009-10-06 02:54:50 AM
I think it's a Nikon but I'm not sure, I'll call him tomorrow and find out. If it's a composite I know he'll want to figure out something else, but it might be HDMI or something.
 
  2009-10-09 08:54:59 PM
So his Nikon is older than I thought, it supports composite RCA only. I was about to give up on this when I changed my search terms, I tried "photo viewer" and hdmi and suddenly the world was my oyster.

I picked the PIE United HD-0310, it can play music/video/photos from USB flash drives, portable disks, or its built in card readers (including CF Type I/II) - exactly what I needed.

www.pieunited.com

On amazon for $57.50 + $11.50 S/H. S/H seems a little high but still not too bad really.

Thanks for the advice guys!

Here's a wee bit of trivia. I upgraded our workshop Vista machine to 7 Pro the other day. Things to note:
Took about and hour and a half, from disc-in to using 7.
Freed up 4GB of hard drive space.
All devices still worked.
All software still worked.
Drive was an 80GB with roughly 50% free when upgrade started, and was still 1% fragmented after upgrade.
Uses approximately 400MB of RAM after boot.

And now I have tried. And lost most metadata. One way that will work is to copy the music from the Mac simply and drag and drop into the newly installed iTunes Windows installation. All names of artist, album, and track seem correct. History and rating are of course gone.

One way that will not work is to copy all on the Mac, edit the iTunes XML file, replacing both location specifiers and line endings, and import the result into iTunes Windows.

Anybody done a Mac iTune -> anything on Ubuntu ?

Ah god damnit.

Everything is all farked again.

It started with a failure for Automatic Update to install Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows 2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 (KB953297)... I have all of the other fixes and updates up to 3.5 anyways and they all installed fine but this one won't install either manually or automatically and I can't seem to uninstall .NET...
A few other updates took two tries each to install but all installed except for Microsoft SQL Server 2005 Express Edition Service Pack 3 (KB955706) which decided it won't install either.

I tried the update batch file fix. It looks like all the other updates are working but these two. I'm constantly getting hounded by auto update to install these two. Even when I shut off automatic update, I still get reminded that these are waiting for an install. I tried doing a system restore, and system restore won't restore to an earlier time, all of the times that I try it tells me that it cannot revert to the earlier time.

Man, what to do next?

N. S. Radieaux's Questions for 2009.10.20


I. How does one go about...

• ...getting Photoshop to detect the original angle of a scanned photograph automatically and rotate the image accordingly (assuming this is possible)?
• ...setting individual twats, rather than all of his twats, to be private (assuming this is possible)?
• ...setting up an RSS feed on his website (assuming this is relatively easy)?

II. When can one expect the release of...

• ...HTML with tags for video and audio?
• ...the rumored Barnes & Noble e-book reader?
• ...Black Mesa?
• ...a kilometers-high, carbon-negative, vertical arcology with a geothermal power plant that doubles as a waste purifier?

III. What is the best...

• ...case for an 8GB iPod Touch (through which one can access the buttons and touchscreen)?
• ...toothpaste (preferably bicarbonate-free)?

• ...getting Photoshop to detect the original angle of a scanned photograph automatically and rotate the image accordingly (assuming this is possible)?

It should be possible, but I have no idea if PS can do this; I would somehow expect the scanner (software) to have such a feature, though I have never seen it (..with the five-ten year old models that were on sale at the grocery store my parents use.).


• ...setting individual twats, rather than all of his twats, to be private (assuming this is possible)?


Shorten the chains on the private ones so they can't leave the dungeon and come upstairs when you have visitors.


• ...setting up an RSS feed on his website (assuming this is relatively easy)?


A RSS feed is just a XML file like this.
Obviously, you can either edit/update the file manually or write a script generating it for you (for example: a web forum or blog might use a PHP file that, when polled by a RSS reader, fetches the latest 20 posts or so from a database and generates the appropriate XML).

Then you add a link to that XML file (or generator script) somewhere in your page so people can stuff it onto their RSS readers to subscribe to it.
If you want Firefox to display that neat "RSS" label in its corner that indicates the availability of a feed for a page, you'll have to include something like this in the <HEAD> element of your HTML page:

<link rel="alternate" type="application/rss+xml" title="MY cool RSS feed" href="http://mysite/thexmlfileOrAScriptGeneratingItOnTheFly" />

As for the photoshop thing, it can be done manually. But you (N.S.R.) were asking for the automatic way. Dunno lol.

Also, for god's sake, no one is allowed to buy an e-book reader. They're like 200-300 dollars. Are you kidding me? Go to a f*cking library.

I know you are looking for the "easy answer". Hell, I would be, too. But quite frankly, there are dozens of things that happen on "idle", both hardware and software related. The fact it happens on idle does not seriously narrow down the problem. Far from being the "obvious symptom", it helps pretty marginally. Take the advice offered in the thread. It's good advice.

The only thing I can suggest at this point is to update the drivers for everything, and I mean everything. If it still doesn't do it, backup, nuke everything, and start over. If a clean install runs fine, it's probably not a serious hardware problem, so should run on a clean install with minimal issues.

You mentioned having to reset the settings on many apps. Perhaps these are proprietary apps that save state, instead of saving to a file? If that's the case, you may get away with slaving the drive to an empty drive, and installing& running windows on that empty drive. When you activate the apps from the D:/ drive, they may look for their local settings.

If you can't even do that, there might not be a good way to back up data for these proprietary programs, in which case you need to hit your boss with the stupid stick. Such a corporation might be one hardware failure from a catastrophic problem.

See if that helps. :)
