i 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.
View 2 RepliesI am trying to write a simple application that monitors the COM port and writes the incoming binary data to a file. So, I gathered a File class is provided, but looking at its methods list in the Help page, I see no method for writing individual bytes (and the Write methods seem to close the file after writing).
How can I write a byte array into a file, keep it open and repeat this as necessary?

View 20 RepliesBase class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

This is my 50th attempt to read the memory and probably my last attempt if I don't succeed now T_T I've been trying to write a class that reads from the memory, simply by creating wrappers around the Win32 APIs but I just can't get it to work.
This is how I currently am trying to read the memory from calc.exe:
Public Function ReadMemory(ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByVal nSize As Integer, ByVal lpNumberOfBytesRead As Integer) As String
Dim tmpBuff As Single = 0

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 have a method SaveRecord() in teh data access layer (DAL) that should return the status of the query execution to the Business Layer (BL)
There are three possible messages the DAL could return to BL: 1. Successfull Execution --> error NO: 12. Error: record already exist --> Error no:23. Error: SQL Errors while executing con.Open() or cmd.ExecuteNonQuery() --> Error No: 3
I'm planning to return error no to the business layer so that appropriate error message can be assignedd.
Is there any issue that my current technique might face becasue i'm not creating a seperate ErrorHandler class to assign those error numbers and error messages?
Should i create a seperate error handler class? If i need to create a error handler class should i create it in the DAL or BL?

bw.Write(0xA000);
writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?

I'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea. There are certain methods and properties these controls all need to work within the app. Right now I am doing this as an Interface, but this is aggravating as all get up, because some of the methods are optional, and yet I MUST implement them by the nature of interfaces.
