View 20 Repliesi have to write a program for my VB class that consists of a resistance checker program. I've searched like a madman to help me through this and I have found nothing >. The program consists of 2 combo boxes, the first one is the nominal resistance drop down list of the numbers :100, 150, 220, 330, 470, 680, 820 and 1000. The second list is of the tolerance numbers; +/- 0.4%, +/-0.6% and +/-0.8%. Now what i want to do is select a number from the first combo box and select the tolerance level of the second combo box and i input the resistor of said value into the text box. when i click the check resistor button it should display a message saying if the resistor is in or out of tolerance. For now I have the form all laid out and the values inputted into both combo boxes and i can go to run the program i am able to select said values. Now my problem is trying to get the right code so that i can check the resistors value.

In C# you can use the implicit keyword to define an implicit user-defined type conversion operator.
In VB.NET you can define a CType conversion operator that will explicitly convert a user-defined type into another type.
Is there a way to declare an implicit conversion operator in VB.NET?
I am having trouble displaying my results from a temperature conversion program. I am sure it is something simple that I have overlooked. Here is the code.
[Code]...
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

View 3 RepliesI am trying to convert an industrial simulation program to a VB program There is one hard concept that I have problem with, it is called "Duplicate" Ex: When 1 person pass the duplicate block A, then 2 persons comes out, (that person is cloned). 1st person goes path 1, has delay time of 1 hour. 2nd person goes path 2, has delay time of 2 hours. At the end of the 1st hour, 1st person arrives at the detour, at the end of 2nd hour, 2nd person arrives at the detour, but 1st person already moves on to the next task for an hour.
So you can consider them doing their separate tasks simultaneously. Then complication comes in when somewhere down the path, 1st and 2nd person pass another duplicate B, then total of 4 persons will run into their own separates paths and delays. Then they will come back to the starting duplicate block A, thus creates total of 8 persons and follow the same path above again.
Until some condition has been met (ex: total number of persons pass through duplicate B), then all of them will leave the system.Anyone has any idea what is the best way (logically easy to follow) to program the concept? I hope I explained it clearly. It's unfortunate that MSDN doesn't allow attaching image or video.
Im trying to make a program which basically performs unit conversion. I have basically made two text boxes, one for the S.I. Units and the other for British Units. The general idea is that when i input any number in the S.I. Unit text box, it should display the answer in British Unit text Box and similiarly if i input any number in British Unit Textbox, the answer should be displayed in S.I.Unit textbox. Now the problem lies here that the code that i created is by using if else. now the compiler automatically gives me the correct result in the British box when i input the value in the s.i. unit box, but when i input the value in the british text box, it gives an error that :
"An unhandled exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Additional information: Conversion from string "" to type 'Double' is not valid."
Heres the part of the code.
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

I am creating a bulk media converter. In order to do this I need to go through each line in a list box one after the other and run the conversion function. I am trying to use the following:
For Each item In listVideos.Items
conversion code
Next
However this makes the program want to convert all videos at the same time... is there anyway to get the program to convert one video and then after the conversion code is completed to move to the next one?Should also be noted that I am using FFMPEG for this project.
i have a problem with my code: [code] At the bold part, when i goto debug my program i get the error "Conversion from string "TrueFalse" to type 'Boolean' is not valid."

View 2 RepliesI'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
How could I write to that, like add another game to it? Like rewrite that but from textboxes but create a whole new game after that game.[code]\...

View 5 RepliesSome time ago, I did some F# programming, the following code is used to serialize/deserialize float32 array:#light
However, nowadays, I have to do some programming in VB.NET to serialize/deserialize float32 array again. As F# programming is not suitable for GUI, but GUI is necessary for my current programming.I want to know how I can rewrite the above code in VB.NET.For example, I have a float32 array, (I dont know what data type in VB.NET is equivalent to float32 array in F#) of (1.0, 2.0, 3.0); I want to serialize it using DataContractSerializer, then read it back so I can still get the same float32 array.

View 1 RepliesI want to write my own global snippets tool for Windows XP and higher. This would be an always running in the background tool that would pop-up on a globally-defined hotkey, allow me to select a snippet with substitution arguments, and then paste the expanded snippet into the text input of whatever control I had been in when activated it, and finally, return me to that previous app/input box.
I know how to do most of the algorithmic aspects, but I do not know how to accomplish these windows-based features:
1 - Global Hotkey: how do I define a key-sequence in windows (from .net?) that will work, even when entering data in another apps textbox? (Usually this will be a browser window)
2 - Pasting Into Another App: I could use the paste-buffer and Ctrl-C, but I want to avoid the extra keystrokes.
3 - Return Control to Original Window: Seamlessly return back into my input stream: how do I do that? In fact, how does my tool even know where I was before it popped up?
The reasons that I want to write this myself is first to learn how (because there are other tools like this I would like to make) and secondly, I don't know of any snippets tools that have the argument substitution that I want.So, the two (2)questions are A) What should be my general approach? and B) how best can I accomplish items 1 to 3 above?
