View 1 RepliesI was just thinking if there is any component which monitors sound output. My intention is to recognize a particular sound coming out from my soundcard. I know its an issue about the driver of my sound card but is there a way I can get atleast noise level coming out of my speakers and maybe draw a graph and detect the peak at when the sound is played?
View 7 RepliesI have an array where it storing all the analyzed values. The ubound array is 2999 and if we plot a chart with y-axis as the values and x-axis as the number of array (0-2999), the chart will look like as similar to the chart shown in the link below. (sorry to say I'm not unable to upload my picture from my pc, no idea what is the problem).I'm able to search for the maximum value (~ -25dB) of my chart from my array with this simple routine:[code]But my problem is I do not know how to find my second peak value, as example, the value ~-63 dB as shown in the chart. How should i write the routine to get this value from the array?

View 1 Replieshow to graphically show an analog needle moving similar to an old analog meter. I have the picture of the meter I created in paint brush. What I need to know if possible is how do I show the needle moving to a certain value. Basically one end of the needle will be fixed in the middle bottom of the picture and it would move accordingly at a certain angle to my calculations of a certain process.

the exe file works beautifully.
here is the problem : in vb i added the volume meter dll and did :project reference to add : progressbargradient.dll, Microsoft.DirectX.dll, and Microsoft.DirectX.DirectSound.dll
and connected webcam with microphone but i get the error "Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang."
My progress meter finishes too soon. I want my meter to end on the last loop. But instead it finishes on the first step of the loop instead of the last loop. I know I am missing something very simple, but I have no idea as to what it is? [code]
View 2 RepliesI'm at a stage with my first real program where I'm putting some effort into the UI.I'd like to have a "meter", of "velocity" type, you know the ones in vehicles.I'm thinking of having an arrow that I've drawn in Illustrator pointing in a specific angles depending on values it gets from a database. i'm thinking of having on arrow pointing straight up, and two similar ones, only being diagonal in the picturebox (to the left and right respectively), thus enabling me to resize the picturebox and stretch the image. However that's not a pretty solution is it? Is there a way to place the arrow at an angle inside the picturebox, or the picturebox itself?

View 3 RepliesIhave written a Visual Basic program to read serial data from an Atmel micro-controller that monitors a solar panel and a wind turbine. I have used a label box to display the digital data from the serial port and all works well.The data from the micro-controller is formatted like this (Battery voltage XX.XX) (Solar voltage XX.XX) etc.I would like to add a analog meter with a 0 to 24 scale to the program that will display the value from the micro-controller but am unable to find anything listed in the help menu of Visual Studio 2010.I have used the terms analog meter, meter and instrumentation in the help menu to look for a template but nothing comes back.Can someone either point me to a visual studio 2010 meter template and or some sample code or best of all.

I am trying to track the progress of a meter in a flash window and click when it reaches a certain point. I am currently using getpixel() to "watch" a single pixel and when it changes to green, perfrom a click. Problem is i have to "watch a pixel" about 20 pixels left of the intended target and then click. Reason, when the program has realized the pixel is green, it clicks, but this has not been as accurate as needed. Sometimes it clicks to soon and sometimes it clicks to late.
Before you suggest using DIBS, i didn't use it because i am loading a 1x1 screenshot and watching that pixel in a loop. I figured since i was continously loading a new bitmap via getpixel that dibs would not be any quicker. The way i read dibs is that if i was loading a bunch of pixels it would be faster because it goes ahead and loads into an array.Is there another way to monitor a meter in a flash window?

I am trying to use a power meter to track the progress of my program; this will be for my use only and will be removed later. I would also like to display the percentage run in the meter. I already know what the start and end points will be for the meter. What do I need to search for? I have been looking and haven�t been able to find anything that suits my needs yet. I am running VB 2005.

View 1 Repliesi am to generate a line graph in vb.net. The graph should be something dynamic. I have a program calculating total distance, therefore in my output window i have iteration number and its corresponding value.
I have to plot the graph as iteration number by iteration value.I have tried an offline graph where i saved the values of the iterations and then draw the graph with the values.
But this is not what i am actually suppose to do. The graph should be generated simultaneously as the processing is being done. I am finding this a bit tough to do.

View 15 RepliesI was writing a program on a web form which is reading a file and then plot the file as a 2d graph.
the file looks like
c1
number1
number2
[Code].....
where c1 c2and c3 is the header which the readfile stream should ignore and the total "number" numbers are decided by the user which can be a variable.
the graph will take the c1,c2,c3values as x-axis and the number values as y-axis.
how can I draw the graph from reading this file? can some one kind enough to show me some code?
