I would like to present an image to a user and then allow the user to interactively define rectangles within that image.
This is a first for me, so I am at a complete loss for examples and methods in VB ASP.NET.
Does anyone know of any straightforward examples around?
I'm using an asp:ImageButton as a custom CheckBox. When the user clicks on it it shows a dotted rectangle briefly. My code-behind immediately switches the focus to the submit button, but how can I keep this rectangle from appearing while the user has the mouse button down?

new to creating a web site. I bought "Build your own asp.new 2.0 website using c# & Vb." and I'm using Visual Studio 2005.
The book seems good so far but I'm now having a problem. I think I need to use "User Sessions" but I can't get them to work. The code works fine using Applications but when I change to Sessions, when I go into a page the value is always null.
I need "using System.Web.SessionState.HttpSessionState" defined but there doesn't seem to be anything after "System.Web.SessionState".
I've tried using the counters example in the book but with Session I only ever get 1 coming up which is the reset value when the Session["xxx"] is null.
In my project I am using a repeater to display articles from a database. I would like to add a link button that calls an asp page and the ID for example the link for article ID "1" would be articles.aspx?id=1

Today we have a windows application that, using an OCX, creates a web page (visible by a WebBrowser control in a small .NET WinForm application) and communicates through COM to the main application/client. (not relevant but this is Pascal)
I'm currently responsible to re create this application in a web environment so we can have the same functionality shared through Web as the user can see the same in a Web Browser.
The Windows application has almost 4 years on it and I need to re create everything from scratch, and all the bugs/features find in the future in the Windows Application I have to re create them again in the Web...
is there any way I can create a Wrapper, even using 3rd party commercial objects, to:
Communicate with the COM Object Can expose the content of the OCX (this in my most confortable language, ASP.NET C#, but other are welcome) I was thinking out loud, can this be accomplish with a Java Applet? Silverlight 4?

View 1 RepliesCreate a Rich Text Format file Add company image to the top of page and write the data to the RTFPrint the RTF file as PDF through CutePDF or other printer that are able to convert my RTF to a PDF and thereby save locally on the users PC - The pdf should be saved at a location without prompting the user After this is done, the RTF file should be deleted and return a message, that confirms the action is successfully done.
Other stuff:
The website where these actions take place, are not meant to host the outcome(the PDFs) but these are supposed to be saved on the users PC. (is this possible without prompting the user to save it? i imagine the website would write directly to the users PC instead of doing the work on the website and save it and then transfer the file to the PC)
OBS: i do not wish to use any 3th party program/DLL other then the converter like cutePDF :)

View 3 RepliesI am a beginner at webservices.
I created a webservice solution using VS2010. I can browse to http://localhost:1259/ResultsWebServices/FG_Results.asmx and click on my webservice which is Get_FG_Results, enter my case num and get the XML back. Works fine as expected. FG
For trial purpose, I added another project in the same solution which is supposed to be this webservice client. I added a web refrence to Get_FG_Results. On the default page I added a GridView to display the resuls fetched by the webservice.
I have a method BindDataToGrid being called at the page load. How do I call my webservice from this method to populate the GridView?
What else do I need to do so that this webservice is available to other applications?
In Visual Studio 2005.I have created a Blank solutions(XYZ) and then add a ASP.Net Web Service Project(TESTP) under it.And then create a .asmx file(WEBFI.asmx) and then write a method and add [WEB Method] on top of the method.Now compile it.And then publish it.But in publishing folder I didn’t found any WSDL file which I should call in different machine (which is in LAN ).

I am writing a table view for my ef model - I am not using the designer - I keep having issues with it. So I'm doing it the old fashion way of writing the code - All my tables and stored procs are working but now I added these two views and all is broken!In my SSDL I have
<edmx:StorageModels><Schema
Namespace="MyModel.Store"
Alias="Self" [code]....
I am getting the errors following - - Error 3 Error 2007: The Table 'ProgrammingCategory' specified as part of this MSL does not exist in MetadataWorkspace.
Error 4 Error 2063: At least one property must be mapped in the set mapping for 'ProgrammingCategories'.
I have this statement which is used to create my msgbox dynamically but it is not working unfortunately. see statement below this

This is a simplified example of what I need. Imagine a person table with several different club tables. Every person can belong to any number of clubs, but must belong to at least one club. The association would be a 1 to zero or one between the person table and each of the club tables.I've created the databases, then the entity model. The associations are all 1 to many, which isn't what I want.
Is there a way to modify the database so that the model is created correctly? I'm still building the project, making lots of changes, and I've had problems with updating the model, so I keep recreating it. Setting up the database correctly would be preferable.I'm trying to follow the quickstart here: [URL]but I'm using the SQL Management Studio designer, and I can't find how to fix the associations I add.
I've been reading about using or not using foreign keys in the model, but it's only confused me more. Can someone help me understand this? I'm starting to write code with what I have, and I'm running into problems. I'm about to start using joins, which means I'm trying to use a hammer instead of a saw because I don't know how to use my saw. I'd rather understand my tools and use them the right way!
