This program is being used to analyze an excel document with coordinates for a robot. The entire program works...My boss indicated he wanted me to throw an exception in whenever a coordinate that wasn't being given a tolerance wasn't supposed to move, he wanted the program to give an error message. Which I figured out and outputs a message box saying "Result Compare Fail!"
Now here is my dilemma..whenever I encounter a section in the excel sheet analyzing multiple variables, I still get the error message, because the program doesn't think of it as multiple variable coordinates changing. Is there an easy way to fix this? I'm stumped! This is one of the cases, but they are all very similar.

View 2 RepliesI am developing an application which is pretty much a replacement of a hyperterminal. I am trying to send commands to the serial port using MSComm in VB6.0 When I type in on the hyperterminal h003128 I get a response OK. Or when I type in i003 it displays back some values.
What I am trying to figure out how do I send the h003128 via VB6. I believe I've undertood how to send data to the port. It seems I am not getting the correct formate. This wont work.. the formate iAAADDD where i = i AAA = 003 and DDD = 128 MSComm1.Output "i003128"
I am trying to read data from an external device using MSComm control but the problem is I am getting wrong data. I am recieving 1 byte data but the first three bits are wrong so anything greater than 31 sent from the external devices is recieved wrongly. eg. if I am sending 63(111111) from the device then the input from MSComm control gives me 159(10011111).Due to this reason I tried SerialPort from .Net framework and was surprised to see that it is working properly.
View 3 RepliesI'm wondering how I could monitor a serial port for a voltage change or contact closure and have an event triggered when there is a detection.

I have a search page in my application where I am searching the database for the records that meet the specified conditions that the user selects. All of this works by creating the dataset, datatable, and dataadapter in the code. I then take a created bindingsource link it to the created datatable and then attach the bindingsource to my datagridview to display the results. Now what I am trying to do is to figure the Mean, Median, Mode and Standard Deviation of the results that were found above. My question is how to I run a select query on the code created table. I have the select query I want to use and when I try to use it in the code it talks about the connection. Now I have a dataset that is part of the project and I have the on just for the search page. Let me know if you need any code samples.

First off, my apologies for being a complete Newb! I have a SQL Express database that I use quite successfully to track my investments in several accounts. I built it myself, it's quite functional, and Im happy with it. The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month. Tedium can lead to errors¦

Running off my laptop: Visual Basic 2010 Express & SQL Server 2008 . I've successfully been able to use the connection wizard to connect to my database in vb.net and read/write data using datasets/tableadapters/binding_source etc.
Now I am trying to create an SQL connection via code to connect to my database to do some more complicated queries. I was successful in being able to connect to my database with SQL, but by doing so it produces an error when it tries to run any .Fill() methods from my TableAdapters below. The error produced is the following: "SqlException was unhandled. Cannot open user default database. Login failed. Login failed for user 'Chris-PCChris'".
If I remove my SQL connection code, the TableAdapter.Fill() methods will work fine.
