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'm implementing a client server from Atheist's thread about the TCP connection. I have set up a host that stores all the user details and when the user connects to the host, the specific user details will be sent to the client. One of the details include an avatar image. Since the example is sending data via text, how do I send an image from the host to the client and vise versa?

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:

I'm trying to make a simple character converter i.e. (A converts to O) or (C converts to V) I need to make defined parameters for the entire alphabet.I have two text boxes set up and a command button. I'm trying to make it so the text inputted into the first textbox is converted (using the defined parameters) Into the second textbox with a click of the button.
View 5 RepliesI'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.
View 2 RepliesI 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.

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.

View 3 Repliesi want to make a temperature gauge using scroll bar (refer to Attachments) it has label to show the text of current temperature and if you are noticed the are also two labels in blue and red which indicates coolness or hotness.the problem is when the temperature reached certain point for example 50 Celsius,the color label is not working.i mean initially i set red label,visible = true thus make blue label visible and it indicates the temperature is still cool but when scroll it to 50 Celsius,the red label is not shown up and blue label is still there.also not working when i decrease the temperature less than 50 Celsius.

I'm new to visual basic and have decided to make a temperature conversion program. I've attached a screenshot to aid in my description. The program reads the temperatures on the left(from text boxes), converts them, and displays the answers on the right in text boxes. The program has a fever check at the bottom which displays whether or not the converted values are a fever.
I've managed to get this to work no problem, but I'm trying to get it so if the user enters the temperatures directly into the "result" textboxes, that the fever check still works. Unfortunately I'm having no luck, the fever check will only display a message if the values have been converted, not directly entered by the user. Here is the code I tried(fever.Text is what is displayed in a textbox above the fever check button):
Private Sub FeverCheck_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FeverCheck.Click
'Turn string values entered into Decimal Values so they can be compared to decimal values
Dim fahrfever As Decimal
Dim Celsfever As Decimal
'The following two lines have problems when debugging

i'm trying to make a converter, i have 4 textboxes, 2 of them are encode, the other 2 are decoders.
on the encode process i use:
[code...]
I want it to be decoded when a button is pressed, because I cant use the KeyPress or KeyDown function because it will most likely be copy-pasted.
how would i do that, for instant the char A Will be converted from "W11" to "A".
Now i know there is a function called Convert, but i have no idea on how it works or if it even is proper for this task.

In short, I want to offer some kind of Expression feature to my users, unless it is too much work, as this project is not the most important one and I don't have like 2 years to develop it. I think that the better thing I should do is to write something like CustomExpression that could be passed in parameters to some functions or subs.
I recently started working with Vb.net and I am just trying to create a class that has two properties one is StoreName and the other is StoreImage. What I am trying to do is figure out how to create objects using this class? Each object will be a Store that has a corresponding Name and Image to go with it. Here is the code I have written so far although I am not sure if im headed in the write direction with the function. Also not sure if it matters but I am using ASP with VB?

VS2008 VB.net. I have a simple Product Class with 20,000 records:
Product(1).partno = "3999399"
Product(1).desc = "Bearing"
Product(1).loc = "34"
This represents ONE sale only and may appear in 100's of other records
Using LINQ how can I: Determine the total count of each partno and then sort by descending order
Example:
Count Partno Desc Loc
3,232 3999399 Bearing Loc 34
2,323 3899388 Bushing Loc 35
etc.
I need to print a simple receipt to my EPSON-TM-T88V thermal POS printer with VB.NET 2010 on XP (eventually to run on Windows embedded POSReady) via USB.All I need to print is some text and a logo. I have my logo stored on the printer. So, I need to use Epson's ESC/POS commands. So, does it make sense to use Microsoft.PointOfService? Seems like a lot to go through to send some escape sequences to a printer!Apparently, the PointOfService system has not been updated to work seemlessly with VB.net 2010 (details below) That is why I wonder if I am taking the wrong path.IF this is the right path...here is what I did and where I am stuck.
For people trying to us the PointOfService classes in VB 2010:First you need to download and install the POS.net (Microsoft.PointOfService) - free download MS. Then you need to add references in your vb.net project. When you try to run it, you will probably get an error something like this:
{"This method explicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch.
