Save Video Data Into Image And Convert Into Bitmap Format

May 25, 2009

I have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30

'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:

'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---
[Code] .....

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

Convert A .NET Service To Native?

Aug 20, 2009

I need to convert a windows service written in .NET into native code, independent of the .NET framework. I've looked into using NGen to do this, but couldn't figure out how to use it. Essentially, I would like to take my windows service, run it through *insert app here* and have it bundle together all of the dependent dlls from the framework into their native code equivalents, so the service is installable without the framework.

C - ExecutionEngineException Thrown When Calling Native Code

Oct 17, 2010

I have a function that is exported by a C library with the following signature:

extern "C" BOOL Func()

The function is declared in VB.NET code like this:

<DllImport("mylib.dll", CallingConvention:=CallingConvention.Cdecl)>
Private Shared Function Func() As Boolean
End Function

The problem is that I get an ExecutionEngineException when I call the function from .NET code.

Given that BOOL is typedef'd as int in this C code, should the declaration be different? If so, how should I be declaring this? As Short or Int32? Do I need to marshal the return value?

C# Implement Late Binding For Native Code

Aug 14, 2009

We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?

Convert Date From US Format To UK Format?

Dec 15, 2009

All of my regional settings in control panel are set to UK but when I retrieve a date from an SQL database (run from my PC) in my program, it appears in the MM-DD-YYYY format rather than the DD-MM-YYYY format that I expect.

After a bit of troubleshooting I found that this is because of the fact that SQL server always stores its dates in that format - so then when my program reads the data from the database it interprets it as being the US format.How can I convert this to UK format bearing in mind I am working with Date objects not strings?

.net - Convert Raw-Image-Data Into Image File (*.jpg)?

Apr 28, 2010

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
