I'm planning to create an application that counts the number of calls recieved based on the type of calls. For example: When a person gives a call an audio menu provides various options. If the person choose option 1 then the count value under option 1 will increment;If the person choose option 2 then the count value under option 2 is incremented, ect, ect,ect.
View 5 RepliesI need to read 10 images in 1 folder and do feature extraction onto 10 images.Does anyone can suggest any good edge detection by using C++ / VB.Net / C# language? After I can successfully detect the edge and write a new image file (in this case is generate 10 new edge detection filtered images, only black and white line image) within the same folder.Then lastly, I do not know any distance measurement able to calculate distance between each edge detection filtered-images (not the original image) and show the result in graph.How can read those images back and get the data of the edge?Keywords are edge detection and distance measurement.

View 1 RepliesI have written a dynamic database driven, object oriented website with an administration frontend etc etc. I would like to add a feature where customers can save items as "favourites", without having to create an account and login, to come back to them later, but I dont know how exactly to go about doing this... I see three options:
Log favourites based on IP address and then change these to be logged against an account if the customer then creates an account;
Force customers to create an account to be able to use this functionality;
Log favourites based on IP address but give users the option to save their favourites under a name they specify.
The problem with option 1 is that I dont know much about IP addresses - my Dad thinks they are unique, but I know people have had problems with systems like this.
The problem with 1 and 2 is that accounts have not been opened up to customers yet - only administrators can log in at the moment. It should be easy to alter this (no more than a morning or afternoons work) but I would also have to implement usergroups too.
The problem with option 3 is that if user A saves a favourites list called "My Favourites", and then user B tries to save a list under this name and it is refused, user B will then be able to access the list saved by user A because they now know it already exists. A solution to this is to password protect lists, but to go to all this effort I may as well implement option 2.

I have a question. I am creating a VB .NET application that opens Visio to do some stuff there. Visio runs a splash screen on startup and the only way to stop the splash screen from loading is to use code like:
"C:Program FilesMicrosoft OfficeVisio10Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio11Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio12Visio.exe" /nologo
For each Visio versions in the command line (but I am not using the command line).
The problem I am having is that I can't run this code from my vb .net application, because my application uses the following code to load Visio:
Dim vsoApplication As Application
vsoApplication = New Visio.Application()
vsoApplication.Visible = False
And I do not know how to call the "/nologo" feature on loading time from my code to skip the Visio splash screen.

My program is in visual basic windows form 2005.
Here is how my program goes.

3.AT+CMGL="ALL"
I also would like to know how to declare these commands as string inside the program.
Here is my program so far:
