Is it posseble to make a webcam input?I dont have a webcam, but i have some orc and simular programs that requires a webcam (I cant change the programs to take another input)I was thinking on that i maby culd make a "fake" webcam input that was playing a movie file.
View 1 Repliesive been steaming on this one for quite some time. Ive got a program that relies on remote control of the computer, and i need to be able to take a webcam image without the user having to press buttons etc. So far, ive gotten to the point where i can find my webcam, and with the help of a button, start a preview, then take the picture and save it as a jpeg.Problem is, when you press the button to start the preview, another dialog box shows up (not related to my code) prompting me to select a video source..Im confused kus it seems as though the list i find on form_load does nothing at all if when i press the button it prompts me with the same list.Well you can infer from this that i cannot use the btnstart_click(sender, e) on form_load because it opens a dialog that wont close until i press ok, and i already tried to sendkeys enter, it didnt work.anyone have any idea how i can either alter my code, or make new code to take a web cam image, and save it with no user input?

How can you access the webcam and microphone in VB.net, assuming the user even has one?
I fail to see a My.Computer.Webcam or My.Computer.Microphone, both of which would probably have been a nice addition.
I am trying to make a GUI that can input data into an exe that is already made.

View 1 RepliesI have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?
I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

View 6 RepliesAfter a long while I started a project in VB.Net. I am making a security cam application for my own room. What I have done so far is capturing image from webcam (15 fps) to a imagebox and copying a still image from that imagebox to another in an intervall I have decided. Afterwards my code saves the image with a date and time as jpg. The code for capturing image I have found in this forum (iCam). My problem is (by the way I am an amateur programmer ) that the first imagebox (for realtime image capture) is not being showed (I dont want to see it). But if it is not active then all still images (saved as jpg) are all black. I think it is a drawing issue. I think imagebox is not being drawn (because it is not visible (actually the form is not visible)) and that is why still images are black. But I really don't know how to fix it? The class for capturing still images is very useful but only works with an imagebox.
(I really tried to understand the code. Especially the function, which copies a still image from 15 fps webcam output to a imagebox (which is used to save image as jpg file). But there are objects like: IntPtr, Hdc (getHdc, releaseHdc) and BitBlt. I really don't know anything about those objects.)
Code of iCam:
Option Explicit On
Option Strict On
Public Class iCam
#Region "Api/constants"

I get realtime images with: iCam.initcam(me.picturebox1.handle.int32) and copy with: picturebox2.image= iCam.copyimage(picturebox1,New RectangleF(0, 0, Me.picturebox1.Width, Me.picturebox1.Height))
I'm developing an application and it needs a facility to take photo of the customer using the webcam.

View 1 RepliesI'm using this code to get the preview window
Dim iHeight As Integer = picCapture.Height
Dim iWidth As Integer = picCapture.Width

As you can see, I have 2 sources. Would it be possible to not show the preview window, but instead loop through all the sources?
That would be in a timer, so like each 10 seconds a pictures is made from each source.

View 4 RepliesWork now since some time on the task to control the microphone of a USB connected Webcam using Vb2008. The required function is simply to switch it on (full level)and switch it off (low level). I used the corresponding API's mixerline, mixerlineControl, mixerlineControlDetails etc but I could not get the microphone reacting somehow. I am able to handle all my Video usable also available code from the forums, but I could not find an applicable code I could modify for this microphone application.
