Create A User Control Using WIA (Windows Image Acquisition) WebCam Project
Oct 6, 2009
i want to create a user control using WIA but i m get a error message at run time Error Assembly generation failed -- Referenced assembly 'Interop.WIALib' does not have a strong name. i m working of windows server 2003.
I've been searching for hours tonight searching existing posts, other websites and all i can find are examples of how to capture a image from a webcam.Does anyone have any code that simple talks to the camera device via WIA, and then saves every image found on the device to a hard drive?I found this code below. Credit i cant tell you as i have a bunch of different flavors of code, but this only saves the file as a tmp file, and not the actual image file i expected after selecting?
I recently posted a WIA sample project in the codebank in this forum here : [URL] What I was trying to do is provide a video preview of the webcam video in a window, but I am having problems with trying to pass in the Window Handle. It should be as simple as Adding a reference to "WIAVideo 1.0 Type Library", and then putting in the following
am build my first windows user control project. It consist of the User Control window and a textbox. The idea is that it will only accept numbers as user input.I have added the controls and code in the textboxes keypress event.Built and added the control to the VS toolbox. Started a new app and added the control to the designer.
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 Build a user control which works as a Login control using Windows Class Library or Component Template:The user control returns the user name and the password It means that the control has minimum two ReadOnly Property procedures. You let the user of your control (he/she which uses your control in his/her software) to set the background colour of the two labels. Create a Windows application to test your control.
It is possible to create windows service using windows form control in vb.net. give me the url or links. The windows forms control such as, Timer control, list-box, notify-icon control etc.
I'm having a problem importing a user control into a new project.I've created and tested a user control using the guide at url...If I choose Debug>Build, a .dll file is created in the release folder.According to what I've read, I should be able to open the toolbox in my new project, right click>choose items, browse to the dll and then import. This all works, but the control is 'greyed out' in the toolbox, so I can't drag and drop it onto the userform in my new project.I also tried importing by 'Add Reference' in the solution explorer and got an error about using a later version of the .NET framework, so I've set both the user control and new project to compile with the .NET 3.5 framework.
I have created a C# user control which I want to use in VB.NET .. the control works fine, but in VB.NET the Intellisense does not show any of the C# user control function descriptions (in summary xml doc tag). If I use the same control in a C# project the Intellisense show each function's description as intended..
Yesterday I added a new user control to a project I was working on: right click on the project name "Estimator", then add, then new item, then on the add new item dialog I typed the name of the user control, and I created my ButtonWithCheck.vb control.
My user control appeared on the toolbox, I inserted it in a form, used it, kept working on my project, and everything was fine. I saved and closed the solution.
Today I open the solution and I got an error: "Could not find type 'Estimator.ButtonWithCheck'. Please make sure..."
I have a "windows form" user control--that is, not on a web page etc. This user control has a form within the user control project. However, code from within the user control can't 'see' the form even though it is a public class---I don't understand why this is the case.
So how can I access the controls (a couple of radio buttons) on the form from code within the user control? I tried creating public properties on the form to return the state of the radiobuttons, but this still doesn't work. I get a "Reference to a non-shared member requires an object reference." error
Should I not be able to see the form since it is a public class?
I'm developing a program with a team in Visual Basic 2010.
What i wanna do is to create a textbox (inherits from textbox) with additional one property called MDIStatusInformation which is used to display a tooltip text in a status bar at main MDI form.
When i use this tag <Browsable(True)> _, the control property not list anything there.
I have an error that keeps regenerating when the form is closed and open back up.
1) Windows Form Application (Project: TestProject)
2) Add class in same project:
Public Class Test : Inherits System.Windows.Forms.TextBox
3) Drag and drop into the form within the project (works fine)
4) Close form
5) Re-open form... then error about the class Test in the project not defined
Actual Error: Type 'TestProject.Test' is not defined.
Is there a best way around this besides creating a separate project and putting the 'Test' class in that separate project and referring that separate project in the 'TestProject'?
Modified Added: By the way... i've used Global.TestProject.Test... but then again another error generate with the custom property within the 'Test' class.
Now that I've got this service that runs really great on my 32-bit development machine when I use InstallUtil.exe to install it, I'm ready to take it to the next level and generate something that I can use to install it on my 64-bit production server. I've never done this before, so I'm looking for detailed, step-by-step instructions on how to "publish" this Windows Service that I've written, or make it such that I can take some kind of file (or set of files) and install my service on another machine. I'm looking for a way to do this using Visual Studio 2010. I think the processes are different than in previous versions of Visual Studio.
i want to create an installer of my program.but i want it to be with the aid of a wizardcould somebody tell me how to create it. i dun know how to create an installer.
i create a class library or use already created class library in my windows service project. I have 1 dll file then how can i use that file in my project.?Logic is my Greatest Asset !
I'm coming over from VB6 in which you could use 'user controls' to create reusuable custom controls. They were simple and contained and you can easily create several instances of a user control within the same or other apps. In vb2008 there are user controls but I can not figure out how to add them to forms or or other apps. Can someone please give me the the basic steps to add a custom user control to a form or project.
Vb.net 2008 I create registration user name and password project with Login form using My.Setting.My question when I wrote the username and password in TextBoxes . I want when checked CheckBox to save UserName and PassWord to Login again automatically.
I am trying to create a custom control using vb.net.I have added a image to the user control and the problem I am having is that when I resize the image, the image seems to move as well.I want to be able to resize the user control height without moving the image on the user control.
everytime I resize the user control, it seems to move the image on it as well.Is there a way of leaving the image where it is without moving it as the user control moves?
I'm trying to, for example: Have a button control, and a picturebox(?) control. I need to figure out a way to make the Picturebox image the current snapshot of the Button. Is this possible? Should I be using WPF or something?
I need to show video in a picturebox, and when a button is pressed, capture the frame. I am making a desktop qr reader. I have the qr reader completed and working. my issue is my camera now. I would prefer something that actually works, and doesn't have severe memory leak issues, and doesn't throw an exception after it's first or second use. Would AviCap32 or Direct Show be better for what I want? Which would capture the image fastest, without causing exceptions? I tried using an open source solution called webcam_capture.dll, and it worked at first, but now I am getting an exception that I dont know how to fix. I'm assuming this goes in vbGeneral, and not the Interop and Upgrade. Most examples I have seen, use interop, so I wasn't sure. I would prefer not to use WIA. I have attempted it, and it doesn't work quite right on my computer, and this application will be distributed.
I would really like to get some VB.net program code for still image capturing using a Webcam.I've searched the web for quite a while now but did not get any codes. Currently i have a code for capturing video. In that code an image can be captured, but only with 640 X 480 resolution (Maximum Video resolution for my web camera). The WM_CAP_DLG_VIDEOFORMAT dialog box only allows the resolution to be set up to 640 X 480.
I am running vb.net in visual studio 2005 and i am fairly new to it all, whilst trying to create a windows application i have lost the .vbproj file and am only left with the .vb code that has been created whilst i have been using the toolbox to create the application graphically. Is there anyway for me to recover the .vbproj file without having to redo the whole thing?
