Hello, I think some people here maybe a freelance or one person company or independant consultant. I would like to hear how do you feel about working alone by yourself? What keep you doing this way and how long do you hold on it and if giving up, why? What is good and what is bad about being a freelance? The good part for me is the freedom to schedule the time and work/create things that I like. Bad part is you are alone, no inspiration by others and missing the fun of talking with co-workers etc. What is your experiences? Irene

Hmm... well, maybe we should respect anyone whoever has a firm believing in whatever what . I had a good laugh on few posts recently. Thanks. Irene

I don't know what the other guys talking about here, seems to be quite off topic To the original post, I think those "habit changing" toolkits (maybe more official term should be "management toolkit") maybe hard to be accepted. In a already "civilized" or "advanced" world, people simply just don't like to be driven... just joking Irene

Yes you can do it with vi server. Load all vis you want to document into memory, then get all vis in memory with vi server, open references to those vis (using a for loop with index) and get all controls' descriptions of each vi and save them into a text file with proper formating for easy read back and decode later. That way you can edit the text and read back to assign to each controls using the vi server technique again. Thanks. Irene

There are two types of activeX server you can use with LabVIEW. One is an activeX server provided by other windows application. If your window's application provides activeX control, you can call this activeX control's methods and properties within LabVIEW. You can search LabVIEW examples for that, for example, Excel provides activeX control, LabVIEW has an example to show how to read and write to Excel within LabVIEW. The second type of activeX is LabVIEW itself as an activeX server. You can call LabVIEW activeX server from C++ or VB. Below are the links from NI side: This is the link of calling LabVIEW activeX server from C++: http://sine.ni.com/apps/we/niepd_web_displ...034080020E74861 This is the link of calling LabVIEW activeX server from VB: http://sine.ni.com/apps/we/niepd_web_displ...034080020E74861 In your case, it sounds like the first case that if your third party window's application provides activeX control, then you can call it within LabVIEW. It is the easier way than the second type because all work is just LabVIEW wiring, not writing C++ or VB code. Hope this will give you some hints on activeX control. Irene

Thank you Christopher and others and this forum, you all not only give great LabVIEW help, but also provide some very thinkable opinions on life attitude. Thank you. Irene

In that case, you may want to show the digital display or flashing a light when the value is out of range other than zero value. Irene

Actually I felt not very good for my above reply, that's why I have to reply again here it maybe some of my headaches drive me into narrow thoughts, although I haven't really replied to anybody yet with "Don't ask me to do your homework", I always tried to answer... The "Don't..." answer apparently is not the correct answer to any questions... Generous people are always a look up model and respectful person for me. Sorry for haveing answered the question with "Don't...", it's worse than not answering Irene

I guess I understand how you feel... well, I like the statement "Don't ask me to do your homework". This would be the final answer to rescue some headaches for being nice. Irene

Thank you Rolf. Your kind words all the time is always an encouragement for me. Regards, Irene

I have a LabVIEW software written for golf that was showed on ESPN channel last year. I heard this February it was showed in one golf magazine (golf digest?) although I haven't seen it myself.

Hi Feynman, Snap will get you the realsize of your video device output image. So that is the image size for all-in-wonder. But there are two ways you can make it look more "normal". The easiest is changing the video window size either programmatically or manually drag into the size you want. This does not change image resolution, only for visualization purpose. The other way is changing the image resolution using "IVision_ResizeImage.vi" after snap. Irene

Maybe best embedd your security code in main vi so that no subvi for that used, that way no one can extract that vi from exe file and replace it if they know how. Irene

I think this moving control feature is pretty nice. One usage case can be that customer may want to layout their own screen, even for the same product, but they want different look for their own brand:-). I guess we can save the last locations of controls to a file so that when loaded up next time, it will keep the previous look. It's good that LabVIEW opens up more new opportunities. Irene

Most time you don't really need to write USB driver for the device you use unless that is your own created device. If using USB RS232 converter, it's transparent to your existing software that can talk to RS232, you don't need to change anything in your software, the only thing you need is install the USB RS232 converter driver, then it'll add a virtual com port to your computer like any other COM port. If you decide to use other USB devices, like USB DAQ, you also don't need to write your own driver because most of the USB DAQs will come with drivers and programming interface for your languages such as LabVIEW. Irene

USB hub should be no problem as long as it's self powered, not bus powered. I think NI USB 6008 and MCC USB daqs are using HID class, which is the same class for mouse, keyboard etc. Maybe that's why you suggested to remove other USB devices (mouse?), because they may affect the performance of the HID based USB daqs. I used one of them before from MCC, it hangs/freeze the computer once in a while. Our iUSBDAQ uses microchip general class, not HID, so far we haven't experienced any hanging or freezing of computer. Maybe you would like to take a look? http://www.hytekautomation.com/Products/IUSBDAQ.html Thank you. Irene

I think it's the "G View"="LabVIEW". The view comes from the square, it's like a window and the content inside that square looks like a "G".

The first thing comes to mine mind is the output value maybe infinite ( I have to remind this to myself everytime now after many times forgotten and I couldn't see the real graph due to auto scale of Y). So could this mean that average Joe can be a supper power in certain case?

Yes, it's possible with usb daq to synchronize multiple usb daqs, at least I know with HYTEK iUSBDAQ - U120816. It has an external trigger line, if you tie all usb daqs trigger lines together, and use streaming mode of data acquisition (U120816 is up to 32ks/s, which means if you use 8channels in each module, each channel can do up to 4ks/s which is enough for your spec, 1khz). If you enable the external triggering option, all U120816 will only start streaming after the trigger lines go high. Since the detecting trigger line high timing is in the hardware, the delay will be less than 1ms. And we tested in lab that multiple iUSBDAQs can stream data simultaneously. The testing computer is winxp, 2.4GHZ with 256MRAM, the usb 2.0 ports are prefered (root hub or extension hub). And I think the windows timing for USB devices is very different than for RS232 devices. For information about iusbdaq, check out below link: http://www.hytekautomation.com/Products/IUSBDAQ.html Thank you. Irene

Treat the pointers in LabVIEW as interger U32. Then pass that interger as pointer to next function you want to call, I think it's similar like how you do it in VB. But if your parameter is **(pointer to pointer) you may have some trouble in LabVIEW, hope you only have one *. Irene

Do you mean that you have a 24bit color image and you want to extract the colors to 3 8bit gray image? If so, if you can get an array of the 24 bit color image, then deinterlace the array to 3 output arrays, each output array is your gray image data. But you need to know what is your color image color order, some are RGBRGB... but some image output in the order of BGRBGR... so that you know which output array is R, which is G and which is B. But I guess I may misunderstand you. Maybe you just want an image window or picture control that can display gray image. If so, at least I know IVision LabVIEW toolkit can do it. The image window accept 8bit gray image or 24bit color image. Link is here: http://www.hytekautomation.com/Products/IVision.html Irene

Ok, Ok, I get what you guys all saying, using system/OS coloUr (Ok I want to be more canadian), attributes. But good programming habit maybe one thing, but not the only thing, colours will brighten up your mood which will make you more creative, don't you get that? Another thought just came cross my mind, maybe the LabVIEW programming language should add personality toolkit to it. Personalities like cool (buttons when you press them, they don't react anything), emotional (buttons when mouse just barely over them, trigger the event) and maybe a nagging button for software protection and license warning. Irene

I can understand both of you. You are dealing with the "Terminator" alike customers
