VS 2008 Webcam With No User Input?
Dec 28, 2009
ive 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 using Visual Basic 2008 and I have two text boxes so people can input information and I am trying to get it so it will run a code with user credentials. However the code is giving me an error saying that "Option Strict On disallows late binding."Here is my code so far:
Public Class CIBNA Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK_Button.Click

I have an assignment that is supposed to accept user input of random numbers. The only part I'm struggling with is I'm supposed to make copies of the array after the user is done inputting the numbers. These copies has to be sized exactly to how many numbers the user input. Am I supposed to use a counting variable and if so how?

How would you let the user of a program enter an unlimted amount of numbers ranging from 0-100, and then have the program tell the user the highest and lowest values from the data they entered?The user would enter the data in when they clicked a button, and the program would sort the data out when another button was clicked.

I am writing an app that uses a combo box to list file types for a user to select from. Because a complete list of all options is both impossible and wildly unwieldy, I am only providing about 10 common extensions. I want the user to be able to type in their own file extension if the one they need is not listed. the first item in the combo box is empty by default, but during testing when i type something in their to use as my selection, i get the exception "Object reference not set to an instance of an object." pointed at extensionComboBox.SelectedItem.ToString

I'm a complete beginner to programming alone, let alone VB.net. What I need to do is encrypt a block of text inputted by a user using a keyword that will also be inputted by the user. This is all to be done using ciphertext, so naturally the user would be informed the keyword can not have any repeating characters. I figure the English alphabet will be predefined in capitals and lowercase, then the keyword will be read character by character, removing those characters from the alphabet array and then appending them to the end of it (to create the new encrypted alphabet). How to read the keyword character by character, and then removing the corresponding letter from the alphabet. The best I can think is to check each character of the keyword against each character of the array which I'm sure is much more work than I need to do.

I have a form with multiple panels which hide/show as the user progresses through and inputs data. After they enter data in the first panel, I want a label in the next panel to be equal to one of their inputs. For example, in the first panel they enter their name in Textbox1. They hit next and it hides panel1 and shows panel2. Then I want Label1 in the next panel to be Textbox1 (their name).

If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.

I want to have a go at creating a webcam application, that takes pictures and eventually records video's.This is a purley personal project, its something I have wanted to do for ages. The problem is I am not sure how to start this project. For instance what control can I use on the main user interface to view the picture from the webcam. Also, do I need drivers for the webcam in my code??
I have started the application with the obvious, I have the user interface designed, again not sure what to use for showing video in the UI, would a picture box work??

How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

iam currently working on my uni project and i have encountered a problem with valadation section.My system displays a message telling the user to input any fields that they have missed out on, listing the name of the field. However as these IF functions are in order the user must input the data in the order of how it is in the code. for example if the "consweight" is inputed and the calculate button is pressed, it thinks that all valadation above it has occured, when those fields are still empty.

I 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 am creating a form for work where managers can report when they find a customer's personal information laying around on a desk (we work at a call center where agents answer calls for a wireless cell phone provider, so we take personal information security very seriously). Anyway, I am wondering if there is a way to have a text box autofill with that manager's windows username (since they will need to be logged into their own profile to use the form).

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.

After 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"
[CODE]...
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))
