Build And Display A Simple Diagram That Is Built From Data Entered By The User?
Aug 22, 2011
I wish to build and display a simple diagram that is built from data entered by the user. Because I can't post a picture of the types of diagrams here I'll use the following example. Image a picture of a house as a child might draw it a large square, with a triangle for a roof, a rectangle for a door, and two smaller squares for windows. Now I want to build an application that lets the user enter data and change that drawing according. For example, by entering the length and height of the house the size changes, change the number of windows, size of the door or height of the roof.
Now this may seem like a useless application but keep in mind the house is just an example the real purpose is different but should be as simply drawn. I'm looking for suggestions on make this work. Should I use a paint? or is something like this better done with a tie into the Visio references?

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

I created a simple desktop app (really simple) and did a network clickonce deployment. It works fine on most computers.BUT nothing on one computer (computer A). No message, no start menu, nothing. App has no dependencies other than .NET framework. If I just copy the exe onto the same computers, it works fine on all computers except computer A.Computer A has the correct framework installed. When I double click the exe it does nothing - no message, no error, not showing up in task manager, notta. I tried more than one application and it performs the same.

current version is 2008 I'm trying to build an application with a simple MENU. When the user clicks on a Menu Item i want the container to show some controls, now when the user clicks another Menu Item, the container needs to change and show other controls, and so on with every menu Item the user clicks, one at a time.
I thought of panels showing and hiding for every menu Item clicking, but that would use a lot of memory as ALL the controls would be created, some of them just not showing. I also though of an MDI application, but i dont want multiple forms (with the menu bar) opening inside one form. I just want the actual container of one form to change.

I am currently building a system in SQL Server 2005.
I have a table that holds information about certain insurance schemes such as overheads and other things. These values will change occasionally and currently I administer the database straight through the management Studio.
I would like to build a simple interface that will allow my colleagues to change these values by selecting the company in a dropdown and the current values will populate. They can then edit these values and submit them to the database.
Is this possible in the current Visual Studio supplied with SQL Server 2005 or do I need to get another product.

I had an idea to embed a PDF document into my application somehow.The PDF is a copy of the user manual. I expect that the file will be around 20 KB. This way, if people don't distribute the PDF with my app, they can extract it whenever they need to.

I have built a MVC website on IIS6. I used the built-in ASP.NET Security without Membership, just the way it was implemented in the template solution. It is easy to secure a contoller or action, but now I need to expose the user management to an admin logged into the site. I understand that the builtin ASP controls for doing this are not "best practice" and are a dog to get working. So what is the best practice for offering user management through a ASP.NET MVC application?
I considered using the Entity Framework and wireing it up to the myriad of stored procs. but that seems awkward. I see options for AccountMembershipService and FormsAuthenticationService. That is what the existing project account controller uses. But, I am not fimilliar with either.I can't help but think that this should have already been there from the project template. This is a fundamental part of any website and you were given 15%, why not the rest?

I wanted to display my current logged user data in my aspx web page.But I am unable to do so. I just can't understand how to call the necessary data. I have used Grid view but I cannot find a query that will give me the details of the current logged user.
Code:
HttpContext.Current.User.Identity.Name
but it gives me an error saying "property access must assign to the property or use its value". I don't know how to tackle this.

I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?

I have previously asked a questions regarding DataGridView control:[URL].. now I'm trying to make the first column to include an autosuggestion. ie. when a user types an ID(say, "12") then all the records that starts with it(ie. "12*") will be displayed as suggestion.
And upon clicking an ID, the corresponding product_name will be displayed on the next column. I think, I could do this using Validating() event of DataGridView.
