In the Measurement and Automation Explorer, it shows up and seems to work fine, but for some reason I can't seem to load it with IMAQ in a LabVIEW program. Does anyone have any suggestions on how to get this working ?
Thanks in advance!
IMAQ can't open cameras in MAX and LabVIEW at the same time. So close MAX (or click onto another camera...)
Try to load it with the Vision Express Acquisition vi in LabVIEW, then turn it into LV code (Right mouse, create front panel)
IMAQ or IMAQdx?

I am working on IAR Workbench platform V7.70.1 and I am triying to download a simple code (a simple main with a while(1) only into it), but I'm not succeding to download the code on the processor. I am using the board NUCLEO-F401RE of STM company, based on the processor STM32F401RE. I'm am getting the following message:
Failed to load flash loader: C:\Program Files\IAR Systems\Embedded Workbench 7.5\arm\config\flashloader\ST\FlashSTM32F401xE.flash
If someone is familiar with the issue, some help would save me. I read something about this issue on this link but I did not understand what I'm supposed to do:
Thank you in advance
the solution is very simple -
go to Project->Option->Debugger->Download - uncheck the checkbox "Override default.board file".
have a good day

Look at the ST-Link reset type. Often the ST debug interface can not connect due to the processor state.
Form the menu bar select Project->Options then ST-Link from the list on the left. The Reset box is normally set to Normal but can be changed to Connect during reset which will hold the processor in reset while connecting the debugger before any code can execute.
For me this worked:
I erase my Port with "CrossCore Serial Flash Programmer"
Then under Project->Options->Debugger->CMSIS DAP->Setup I choose "Software".
Then I debug once.
Then I choose "Hardware" in the same setting window.
Debug again.
Then it worked. Some other software might mess up the correct serial settings, thats why you have to erase and reset them.
I have made my VB.NET program installer, the operations with the database works very well, but a new problem presented:
On the computer where I developed the program, resolutions of my forms are excellent as I set, I install the same program on another computer in my house... and this happends
The image on the left , is the computer where I Tested... And the image on the right, is the computed where i develop the program.
I cant see the "Hide window" button on the left... (All forms of my program have this issue)
How I can fix this? :O
The solution of this problem, was playing with the dock property! Thank you Chase Rocker for your help.

I've been playing with a generic usb camera to take snapshots every few seconds. With the help of this SO question, I was able to get the camera working; however, when you click the button to connect to the camera, a dialog box appears.
The difference between the other question and my question is that I have two video sources: a built in webcam and a usb camera. I also intend to have multiple cameras connected, all taking pictures. It appears that when you have multiple devices, you always get the dialog box where you have to choose the device. I'm trying to automatically choose the camera (and eventually cameras, plural) without this dialog box.
There are other pieces of sample code that I have played with - samples that have a device listbox that is populated; I thought this was what I needed (and I'd just remove the listbox control and process the list and what to connect to in code), but every one of these samples populates the listbox with "Microsoft WDM Image Capture (Win32)" instead of the devices listed in the dialog after attempting to connect to this "device."
Surely there's a way to automate the webcam(s) I'm connecting to instead of having to choose it from a dropdown in a Windows dialog, right? How would I go about doing this?
The solution ultimately was to use EMGU to access the camera; this also allows for connecting to multiple cameras at the same time.
Recently , I have created a sketch in Processing-1.5.1 using SimpleOpenNI-1.96 library. A sketch is running fine even on a present mode. But after export a sketch, it gives me a blank gray screen, also kinect's red light doen't respond, even running it from command line, it doesn't notify any error... I only get a blank screen without stop button.
I am working on Windows System 64bit-OS with Processing-1.5.1 (framework) , SimpleOpenNI-1.96 library, Microsoft kinect xbox 360.
I don't know how to fix it.
Need your valuable help...
Thank you...
have you tried to use the newest version of processing ?
in some case, Processing-1.5.1 is not suitable with SimpleOpenNI-1.96
I have written a VB application in VS2010. When I try to record its operation for a demo video with Windows Media Encoder x64 or Apowersoft free screen recorder, I get a recording of everything on the desktop except my application. It's like the application is invisible to the recorder. It has worked in the past (2 weeks ago). It must be something I have done but I'm baffled. Is there a "feature" in VB that can prevent you from recording the Form?
BTW, a still screen capture works fine and sub forms I bring up are captured. Only the main form is invisible to the recorder.
Thank you for your help and time.
Not a VS or VB problem after all. What I found was that windows 7 was switching me from Aero Theme to Windows 7 Basic. The message that showed up was that I was low on display memory. (A quick pop-up in the bottom right corner that I was ignored during the recording). However, I have 4.75 G of display memory?
BTW on a video conf call it produced the same invisibility "feature" until I found the Theme switch.
I haven't actually fixed anything but now know to watch for the tell tale screen blink as it switches mode. I pause the recording, and switch it back before restarting the recording. Got through the recordings I needed for now. I was using MS Media Encoder. I have now replaced it with Adobe Premier elements but haven't tried it yet to see if I still have the problem. Need to get the "how to" videos out the door first.
Thanks again. I have read many of your Answers to others in the past that have helped me solve numerous other VB and VS problems.

That's weird since it's recording forms from the application and not other forms (main form) from the same application.
Make sure you run the recorder as administrator and not the application.
