I'm working on improving a GUI on an application, I have a tabconrol with many pages, I want to put a background Image instead of the unique color which appear behind, I didn't find any property to do it .. Is there any way ??
your help is really appreciated,
So lately I'm having a weird problem with my USB ports. I'll try to explain.
I keep hearing that sound like someone's putting in a flash drive & removing it. Over & over & over. Also, when I look in Windows Explorer, I see a number of "Removable Drives". They must be some kind of virtual drive because I certainly don't have that many pysical drives. They were there when I bought the PC.
At any rate, this problem isn't happening all the time. It just randomly starts. When it's happening, the list of drives in Windows Explorer disappears and reappears at a fast rate in sync with the sound I described.
This is a fairly new PC, and I use AVG and Malware Bytes and scan regularly.
I have a wireless keyboard & mouse, a wireless headset, a printer, and 2 monitors plugged into the USB ports.
I have no clue how to figure out what's wrong. Any hardware people wanna point me in the right direction.
I'm not a hardware-person, but.. if you open the "properties" screen of "my computer", go to "Advanced settings", then to the "Hardware" tab and press the button "Device manager" (or somthing similar, using a silly localized/non English version of Windows atm), you'd launch an app that shows a tree with all the hardware. Try to find the USB-node, and see if Windows tries adding a piece of hardware - there'd be a node appearing and disappearing in sync with the sound.
If you do find one, disable it.
If that fails, download TweakUI and disable every drive that you're not currently using.

Does your computer have a media card reader? If so, that's probably where all those drives are coming from. Each one of those card types has an allocated virtual drive to load to.
Now, to get to your actual problem, it sounds like you're having a problem with some USB peripheral, the drives appearing and disappearing is probably just a symptom of the real problem (i.e. it keeps trying to refresh). The problem can really be anything USB (including your keyboard or mouse) or even one of the USB chips that's malfunctioning (or the power to it is dropping below whatever is it's minimum).
- Disconnect ALL external USB items and see if problem appears.
- Try to find old style keyboard and mouse to drive.
- Disable the media card reader on the device manager if there.
- Start in safe mode and see if problem occurs there.
- If problem still persists... you'll need more experienced help (need to check voltage levels to USB chips, may be problem with motherboard or powersupply... more likely motherboard since the power to the chips should be going through a regulator on the motherboard).
In system config on the target you need to enable kernel debug specifying firewire of serial.
Hook the target to the host with tht relevant cable.
Turn off the target.
Run windbg on the host and set it to kernel debug on the relevant interface (firewire or serial).
Restart the target and it should connect and you will see a lot of debug data.
You then set the path in windbg for the symbols and code for your driver (and use the global microsoft symbol server for their code, search in help for symsrv), then you can set breakpoints and step through your code.
Everyone might have watched IRON MAN series, in part 2 of the series he uses surface computers containing a transparent glass slab , when i read about the details it was like there were laser-integrated motion sensing projectors which just sensed his hand signal and projected the images but i thought whats the difficulty in implementing a surface comp and i even heard MICROSOFT tried one surface computer which did not succeed
Sir,i m talking about the comps which are used in the movie , it like just two glass sheets , i m talking about their implementation . I just wanted to know whats the technology to implement them in reality whereas in the movie its just like a screen on which an image is projected. Usually there seems to be a controlling unit below the screen. Its like a normal comp with it screen made larger.
oh not really that was a joke sir i m planning to build one in the near future, i even had a page bookmarked but by mistake i deleted it in that they had given a brief info about polishing the glass surface and all stuff , so thought might get some ideas of mistakes were done by others and i didnt want to repeat them, since i want to program the LANs now at present as my project in my college ,my holidays are going on so thought i could do something related to hardware
I need to find a device that i can use to secure access to a fingerprint reader.
Basically what I need is a device that:
1) has a female usb input and a male output with a controller device in the midle
2) once joinced to the fingerprint device it will be epoxied together
3) I want then to be able through software to send a command to the dongle to unlock the use of the fingerprint device
Can anyone point me in the direction of something like this ?
What my company wishes to do is restrict use of the device by any software other than the software that it was intended for.
Hey everyone I have this exotic project called SpaceData, it's a project for creating a wormhole and black hole generator in one massive device.
A black hole crushes everything to a small particle, literally. A wormhole creates two gateways at two different points in the universe or space and sucks in an object faster than the speed of light into and forces it out of the other side of the portal.
THE GOODS OF THIS DEVICE WOULD BE: Sucking up gamma ray bursts, massive asteroids, deadly solar flares or bursts from the sun ,and if they existed, an alien invasion. Basically a planetary defense for planet Earth.
The problems I will be facing (at the top of my head) is...
You need money in order to build any device.
I need the steel, iron, power, and chemistry that will make up this device.
Like any device it will deteriorate and go bad, and like device like this left unchecked, if it opens a black hole or worm hole per say in anywhere sensitive or where it's not sup post to, serious bad things WILL happen. Lets just say hell and devastation on planet Earth.
I will need people at my "own page" developing this device together, because one mind developing such an exotic and extremely powerful device is NOT practical; it would take more than my life! to build or even think about making such a device.
V. Device Security
So much power going into the wrong hands can be "hell on earth" with a thing like this. So you need physically impassible barriers to protect this device from the wrong hands. Also trustworthy people with self-control that will protect the device instead of activating behind my back or in front of my eyes.
VI. Personal Security
More than likely, if people know I created this device and/or have it in my possession and/or can use it at my disposal, there will be killers and terrorists coming after me wanting to destroy me or torture me making me feel physical and emotional agony my entire life. Not only that if my own government and/or other governments knows about this, whether by a spy satellite, a spy agent, a word of mouth, or the news, my own county or nation and it's military will be going against me as well, because a good apple can turn rotten, can it not? and my friends will be brainwashed by my government or any kind of enemy that I will be facing and sooner or later I will have everyone against me, including anyone who reads this post and people on CodeProject(R). Just for the sake of (protecting and) having a device.
What I'm asking is, is building and maintaining a device like this worth it? Could I put this on another planet?, Or in a world like this there's too many problems could occur? (like all listed above)
Simple Thanks and Regards,
Brandon T. H.

I do not know how this happened, but it did. Running XP with external USB HDD with four partitions. One partition name just disappeared. Disk Manager reported correct size and “healthy”. Explorer had “Local disk” for name and reported disk corruption when I tried to open it. Windows Task Manager Performance was hovering around 100% and my start up programs ( about 5 ) would take forever to load and everything else was just crawling. There were no unusual Processes running. Virus scan took forever and reported no problems. Finally the 100% usage problem disappeared by unplugging the USB HDD. The faulty partition was just a temp, luckily, so I rebuild it and all is fine.
Any speculation why the OS was overloaded and with what?
Sounds like it could be a file system mini-filter or legacy filter driver. You can query the FltMgr and check for attached mini-filters. Open an Administrators prompt after connecting the USB HDD and type:
Thanks for reply. There is also another weird thing happening. Periodically I get the "Autoplay" running for no apparent reason. I have not looked at it in any details, since it always happen when I do develpment. Than I do not want to futz with it then. What really bugs me - after total power down the original disk name will be back. But it makes me nervous because the first time this happend it never came back with the original drive. But it definetly affects USB devices only. I'll have to learn more about USB.
What you are describing would be consistent with my previous post. Many USB disks have an auto-play INF that installs device drivers for encryption or other purposes. I *highly* recommend that you disable auto-play.
The reason your auto-play prompts you randomly is probably because; 1.) have auto-play enabled and 2.) one of your disk devices is becoming detached/attached. When the hardware arrival event fires auto-play will probably prompt you if you have it configured in this way.
The reason your USB disk device is randomly attaching/detaching could range from faulty USB connector... all the way to driver conflict. In the past I have seen this happen when a security product would scan for USB devices.
I've just inherited a setup at my new job. I formatted and installed Windows 7 Ultimate from scratch, then updated my display driver, a Radeon HD 2400 Pro, but my one monitor remains blank. It is wired correctly, as when I updated the driver, I had a few moments when it was live, showing Windows desktop background, and on a few other occasions it does this as well, but it always goes blank after a few seconds and stays like that until the next brief event.
i trying to build up a program that send a bitmap to the lan printer directly to the ip address
i'm looking for code (c#,c++) that can make the job like the printer driver do.
something that can "talk" with the printer and send directions and data.
i have a service that sends thousands printings to several printers (lan & wan) and it's take long time until the page go out,
getting the driver from the print server, init the printer, spooling (in the server that spool the printer hardware...)
i realised that if i install simple driver(PCL5 etc..) for advanced printer it's work faster!
where i can find piece of code that send to the printer ip some instructions for start ?
I have got old drum machine with 240x64 LCD screen,
What I want to do is send signal from ribbon LCD to PC and encode to see all information on PC screen(240x64 is very tired to looks for 4-8 hours when I work in the studio)
This ribbon coming from drum machine mother board after lc7981
How to connect to PC ?(USB board or pallalel)
ON that ribbon I have got this data:
pin on LC7981 and data:
5.MB LC drive signal
10.FLM Frame signal
11.CL1 Display data latch signal
46.CL2 Display data shift clock signal
47.D1 Display data Upper SCreen
do I need anithing more?
Any LCD simulator in PC or Mac ?
Or I need to read my program ?
