Decimal To Binary Conversion?
Mar 6, 2010I write a program to convert Decimal numbers to Binary numbers. It is working well. But I want to control the bits. i.e - We can write 31 as a) 11111 or b) 011111. When I run my program it displays 11111. I want to take input bit from a text box and display it like 0011111 or 011111 or what ever bit I input. How can I do that ?

View 6 RepliesConversion To Integer, Decimal, Double
Jun 9, 2011So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.

Conversion From Type 'DBNull' To Type 'Decimal' Is Not Valid When Field Has Data?
Feb 7, 2012I am pulling data from a local MSSQL database using a stored procedure, then send the data to a web service. Every part of the component works well except for a pesky problem will a DBNull being returned from the DataRow field, when I know that the field is not null and has valid data. The database and associated INSERT statements that add to this field are designed to not allow NULL entries. When I debug break the program on or right before the line that throws the error I see that the field has valid data for the current row.If I add a null check to the code (as below) the operation continues as normal:

Why is the read operation returning DBNull instead of the data in the database?

View 2 RepliesText -> Excel Conversion (with Extensive Formatting Required After Conversion)?
May 11, 2012I'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?
