What I'm trying to do is upload a file (image) to (possibly) a new directory. My logic is as follows;
If NOT Directory("[URL]" + UserID).Exists
CreateDirectory("[URL]" + UserID)
UploadImage("[URL]" + UserID, Image)
Else
UploadImage("[URL]" + UserID, Image)
End If
Is there a way to do this with WebClient or HttpWebRequest?

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?

View 8 RepliesI 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:
Me.Cursor = New Cursor("Patch..")

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?

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).

View 3 RepliesThe program i am trying to build populates a series of textboxes from a csv datafile and picturebox upon text change.The problem I ran into is that if there is no picture for a particular record the rest of the record doesnt populate into the textboxes
My thought, and perhaps someone has a better idea on how to handle this behavior is to have a default image loaded in the event, no image was present.
[Code]...
If this is a good way to handel the behavior then my question is where would the default image be stored? The program would have to be compiled with the default image? I have yet to compile a program before, getting close though

I've developed an application that acquires images from my Logitech QuickCam Pro 9000 using WIA. The problem is that I cannot figure out how to adjust the quality of the image taken by the camera. The camera has a 2MP lense, but the program will only acquire a picture of 320x240 pixels, which is the lowest resolution the camera has. How do I tell the camera to take a picture at one of it's other resolutions? IE: 640x480, 960x720, 1.3MP, or 2MP?

View 4 Repliesi have been in state of hectic for the last 2 days making lot of research and finally made this code worked it for me. My problem is that, how can i make this code retrieve the image from sql server database...use picturebox to load it in the vb.net program.

Is it also possible to change the location of image where its getting the image. i mean, i would like to tell other computers to get their images from anywhere as long as it brings images to my server.i mean, say that comp1 which is connected to my database server for storing and retreiving information, gets his image from his location then the application sends the image to my server...the application retreives the image from the server..as simple as that.
I have a table in SQL Server with a field defined as Varbinary (MAX). In VB I am trying to save an image to the table. The file I'm using is 139kB in size and I get no errors but when I look at the record, the Attachment column where my image stream should be is empty. The rest of the information is saved. I checked the buffer and it grabs the correct size of the file (141475) so I'm very sure it's found and loaded the image.
Could the parameter from the SQL not be passing the binary value to the parameter properly?

View 2 Repliesi am creating a winform program using vb where i am loading an image into a picture box. then in the mouse down event i am creating small circles which can act as points which will be displayed on the image. say creating five points around the eye of a bird. then i am having a button by clicking it , a polygon will be drawn on those selected circles x and y as edges. i am having no issues until this. when i am trying to add another polygon in the same picture by clicking around its leg or whatever and pushed the draw button there must be another polygon i.e. two separate polygons 1 on eye and 2 on leg. but there is only one polygon from eye to leg. so my questions are
1) how to close a polygon and draw another one in picture box
2) how to select a previously drawn polygon and delete it.
