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?

After scouring the forums for a code to extract icon from exe and convert to bitmap, i got that working, and the image will display on my form just fine. I want to save the image so it can be loaded again after the program is closed, but I get "Generic error in GDI+ occurred" when I attempt to save the bitmap.
Dim ExeIcon As Icon
Dim button1icon As Bitmap
ExeIcon = System.Drawing.Icon.ExtractAssociatedIcon(Filename)
button1icon = ExeIcon.ToBitmap()
Button1.BackgroundImage = button1icon
button1icon.Save("C:utton1icon.png", System.Drawing.Imaging.ImageFormat.Png)

View 4 RepliesI have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.

View 2 RepliesI have a screencasting program where it takes 10 screenshots every second and saves it to a temporary directory then through ffmpeg the series of images are compiled into a video format. My problem is that due to the computers processing power or the size of each screenshot and its quality it sometimes takes longer than 100 Milliseconds to create one causing the whole video to be off balance. How can I ensure 100% that 10 Images will be stored?

I've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.
