I'm attempting to grab an image from a webcam without having to connect a driver to a window. I'm predominately using code from a devx tutorial. On page two of the tutorial, it shows how to grab a frame using WM_CAP_EDIT_COPY. The only problem is, I don't want a preview window. I want to simply grab the image without having to associate a window handle to a PictureBox for previewing.
Is there a way by using ASPxUploadControl to have an image get uploaded automatically when you click the ok button after browsing and then get shown a preview of said image but only upload the image to the server officially after you click an ok button? I found [URL] which looks like it does the automatic upload but thats about all I've found so far.
Im looking to embed an .exe into my form. An example of what I want to do is the preview area when selecting a screensaver in Windows. It shows a small running preview of the app in the current window. How do I do that in my VB form?
I have this as code to run the program Process.Start(ListBox1.SelectedItem.ToString.Split(New String() {" "}, StringSplitOptions.None)(1))
Which used to work but then I added a "Preview image" function like this : (ListBox1.SelectedItem.ToString.Split(New String() {" Image:"}, StringSplitOptions.None)(1)) I now discovered that the first code is useless, because it selects everything after " " to run, including the "Image:"
This is how a listbox item is stored: Tomb Raider Level Editor - Original C:Program FilesTomb Raider - Level Editor omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp
As you can see it'll use this C:Program FilesTomb Raider - Level Editor omb4.exe Image:C:Program FilesTomb Raider - Level Editorload.bmp to run Is there any way I can make it choose the path from " " and when it finds "image:" it stops?
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
I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:

I'm trying to build a project where I have a set of products in a listbox. When you select an item in the listbox, a picturebox shows the preview of that certain product.I practically finished the entire project as well as the picture part; however, I realized that the way I set up the coding, I used image locations from my hard drive meaning that someone can't view them on another computer.This is a portion of my coding:
[highlight="Dim PicSelection As String PicSelection = ListBox1.SelectedItem Select Case PicSelection[code].....

My plan is this: 1. input the picture to a picture box no 1 2. load into memory 3. extract all value to a 2D array matriks 4. process the picture 5. Show the result in picture box no 2 6. End
I met a serious problem when i want to load it to memory. For a faster process i use Graphics class (i've got this trick from my friend). but later I found out that graphics wont work for PixelFormat.Format8bppIndexed.
Here's the code:
Imports System.Drawing.Imaging Imports System.Runtime.InteropServices.Marshal Public Class LockImage
I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?
I run a software development firm that develops application for Windows Vista or higher. Windows Vista has a new feature called large icons, that allows display of up to 256X256 icons.
However, if I make an image that contains this icon file, the image just assumes that it should use the 32X32 one in the ICO file, even if I scale the image up to like 500X500 (in that case, it just scales the 32X32 one up).

The coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim fileSize As Integer Dim rawData() As Byte
