I am new with Visual Basic and I am creating a aspx temperature converter application in Visual Studio 2010 where the user is able to input numbers into a textbox, choose what type temperature it is through a dropdown listbox, and choose what temperature to convert it to from a radio button list. The problem I am having is that I am getting an error when I try convertingrr something. I get the error "Input string was not in a correct format" and "Conversion from string "F" to type 'Boolean' is not valid." I've tried doing nested if..elseif..endif statements, but when I do that it just converts the 1st if statement and nothing else. Here is the code I have written for the conversion.
I'm doing a little app that basically has 2 text boxes. You'll enter Fahrenheit into TextBoxA and Celsius into TextBoxB.As the text changes in TextBoxA I want the equivalent Celsius value to be displayed in TextBoxB and vice versa.Is there a way to do it all in Xaml except for a Convert class that does the maths? So basically I want the TextChanged event of one textBox to pass in it's value into a Converter class that is evaluated and sent to the other TextBox and visa versa.
Below is my code which is almost complete. The only thing that I need to do is set up an autoupdate feature that keeps an ongoing average of each temperature that I enter in. I have no idea how to do it!

I've pretty much have this assignment done. My main problem is to get the math to pan out and it's making me crazy. It's gotten to the point of staring blankly at my screen for the last 4 hours.I'm hoping that someone would be willing to take a quick peak and give me a shove in the right direction. The purpose is to type in a number in a textbox then choose using a fahrenheit radio button and a celsius button to calculate the corresponding conversion in a label box.
I am working on a school project to make a temperature converter that when fahrenheit is entered into textbox1 and then tabbed, the conversion to celsius, rankine, and kelvin is displayed in textbox 2,3, and 4.My instructor showed me how to input the code for this, but it isn't working correctly. I know I need more code to get this right but I am a newbie to programming and my instructor doesn't insruct very well. Can someone please tell me what I need to do to finish this coding? This is what I have so far: Public Class Form1
I decided to make a simple temperature converter (C to F vise versa) for class since I already had made a calculator. But for some reason, it won't work because it can't convert from string to double. How do I fix it?
I need to write a paper on the comparison between (Microsoft Visual studio 2005 to develop web applications using asp.net) and (visual basic and Netbeans to develop j2ee applications using java).I need suggestions for good webpages,journals or documents which can help me out here. I have to write at least 1500 words so any suggestions are welcome.
In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.
Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.
I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.
I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version. If he chooses the premium version, then I want it to say premium in his "receipt" later on and if he chooses standard, then standard in the receipt.
I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.
I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.
I have visual studio 2008 installed and was using C#. I am now trying to find Visual Basic. I can't find it. Is there a way to download it or should it be somewhere in my visual studio program? I don't want to use vbexpress, just regular VB 2008.
I recently loaded my copy of MS Visual Studio 2008 Standard Edition, with Visual Basic, on to my new laptop, one with a Windows 7 operating system.

The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG). Also,

I have been working on a game development program for a few days now. And have come to a halt on one part, and thats adding a 3D space in the program. I do not know the code for this, would some one please provide something i could use for adding 3D space in my project? for example, i have a panel set up to be the view port in to the 3D space.

I'm looking for options to fill a Word Document from either Visual Basic, or Visual C#. I'm currently using merge fields, and the code below to fill specific fields in a Word Document, but now I've run into a situation where I need tabular data pushed to MS Word. Is there anyway to take data from a grid view (number of rows is dynamic), and import it into a Word Document Table using a merge field or something of that sort? I have to maintain the format of my template doc, and would like to be able to control the layout of the page
Visual basic dot.net that runs on visual studio 2005, thats what i have, is it the same as vb2005? If you're not living on the edge, you're taking up too much room
I'm trying to just get a VB.net app to be able to execute a lua script in a external file, and be able to add some functions to lua too, To do this I have this code:
Imports LuaInterface Public Class Form1 Public luascripting As New Lua() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click luascripting.RegisterFunction("DisplayText", Me, Me.GetType().GetMethod("DisplayText")) luascripting.DoFile("script.lua") End Sub End Class
But it errors on the register function, saying "Object reference not set to an instance of an object." Do you know of a example VB.net project that uses lua? Or know how to fix this?
