I'm trying to convert some of my code from EXCEL VBA code to VB.net. However I've been encountering some errors and can't seem to get to display the output correctly.Below is my sample text data:
I'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?
[URL]..a good way to create Excel files without using Ms Excel,but this is C# source code,I used [URL]..to convert from C# to VB.NET,but after conversion There are some strange errors :

I'm coming to the conclusion that the things I want to do in a database are better done if I run a conversion code from Excel to Access, do mighty things in Access, then have the option of converting back to Excel to distribute elsewhere. I'm already familiar with using Access and the code I keep finding in threads almost always refers to .mdb files. Below is a conversion that does not seem to work (button2). I'm trying to do this through ADO with OleDb connections. If I can convert to Access much will make sense.

I have 3 textboxes in where RGB colors are added. Now I've added an extra for HEX color. When I tried to convert the 3 textboxses to HEX I found that the output is wrong. Seems I'm doing something wrong.
Dim conv2hex As String = System.Drawing.ColorTranslator.ToHtml(Color.FromArgb(color_map_txt_r.Text & color_map_txt_r.Text & color_map_txt_r.Text)) color_map_txt_hex.Text = conv2hex.Substring(1)

The correct conversion would be: a90266, but the result is: 155111..
I am trying to use a spreadsheet with VBA macros that I wrote in Excel 2007 in Excel 2010.When the macros run in 2010, I get the error message "Can't find project or library" on functions like UCase and Date.I've set the macro settings to "Enable all macros" and selected "Trust access to the VBA project object model."What do I need to do to get these macros to run in 2010?
I'm creating a simple personal calculator, it only has 1 textbox and 1 button.my code is:

I need to import a .csv file so that it formats it all nice-nice so I can easily get the information from a column or row, then I need to grab certain rows, then reorganize it and save it into a different Excel spreadsheet for the program to then use. The original .csv does not contain the information in a way that we need it to be.
What I found so far: I saw this code snippet online
'----------------------------------------------------------------------- ' CONVERT CSV FILE TO XLS AND PROCESS XLS ROWS AND COLUMNS ' Opens Excel, imports .cvs file into xls format ' Iterates xRows and xCols from xls format

I have eight text boxes each can have any numerical value only consisting of the numbers 1-8 up to eight digits each. No 0's or 9's. I am using a timer to loop through the sequences of text boxes at a given rate. This is already configured.
Now here's the hard part so bare with me.I need to output the first value of a text box, wait some time then output it's counter letter (below the number on the keyboard), go to the next text box and repeat. Example:

Ultimately I'm trying bring my PC Interface project up to date by going from a parallel port to USB. This will be the "Custom Loop" function for the device.
I have been using this code for a long time now and it has always been accurate. I recently tried to convert a large string from one base to another and some weird stuff happens.
When I convert from base 36 to base 10, the result is accurate. When I convert the result back to base 36, it becomes inaccurate.

I am working on a project where I want to convert all the mdb files in a folder to xls files in C# or VB. Here user will select folder and then all the mdb files in that folder should get converted to excel files having same name. Also mdb file can contain many no. of tables and and I want each table in mdb file must be converted to different sheet having same name as that of table.
I am trying to convert text in a text box (txtEventDate.Text) to a date type in a structure: ThisEvent.EventDate (declared as date). The text in the textbox is of the form: 05/18/1927 (i.e. May 18th, 1927) and after looking long and hard thru the forums attempting several different things, like:
The code is commented out because none of them convert the string to a date value (I know a date does not have a format and I have looked thru the MSDN). How can I stay logged and composing a thread past some arbitrary time limit that forces a re-login?
I have a fairly lengthly block of code that I'm trying to convert from VB6 to VB.NET.

I have written this code and tried running it but I am getting errors in the code segments below. The error says "conversion from string to double is invalid". whereas the calculation for 'y' is an addition so should not be giving the value it is giving at the moment. ICCPtotcircuitres is also returning 'nothing'.

I inherited a program that retrieves 3 datasets from our vendors' web services, converts it to a table and then merges the 3 tables before exporting into xml from the resulting combined table. The problem I am having is that when web services returns an empty dataset the program crashes in the attempt to create a table from the empty dataset.How do I modify this code to either create an empty table or recognize the empty dataset and skip around that particular table creation, merge and removal? There is always data in at least one of the datasets.

My startup form displays a login box and then, upon successful login, displays a series of buttons. One of the buttons displays a form named Calculator using the following
[code]...
When stepping through the code after clicking the button that calls the above code, it gets Calculator.Show and then jumps to code on the Calculator form that fires when a checkbox on he Calculator form changes checked state, apparently bypassing the Calculator_Load procedure altogether.This eventually results in the following error:{"An error occurred creating the form. See Exception.InnerException for details. The error is: Conversion from string "" to type 'Double' is not valid."}With the IDE claiming the error is occurring on the Calculator.Show() line on the previous form. Clicking the button a second time causes the form to load as expected, with everything working corectly.The load procedure header is:Private Sub Calculator_Load(sender As System.Object , e As System.EventArgs) Handles MyBase.Load Am I missing something in here that would cause that not to fire first upon a Form.Show call?Possibly relevant is the fact that I renamed the Calculator form prior to the problem arising, but I've searched for the old name and there are no vestiges of code still referring to it by that name. I also tried renaming the form back to the old name, but that didn't fix the problem either. (Plus I seem to recall having ran the application several times after the name change before the error was encountered, so I don't think this is relevant but didn't want to leave it out, just in case.)

I'm unsure if this should be in Office Automation or here, but I opted for here because I'm creating a VB.Net program to handle all of the office automation and my questions are a combination of the VB.net portion and some of the VBA formatting.

I am currently in programming class and I have tried time and time again to complete a form called "theater revenue" that was assigned to me. Even though I have typed in a lot of code, it keeps telling me "Conversion from string "" to type 'Double' is not valid."
These are the directions: "A movie theater only keeps a percentage of the revenue earned from tiecket sales. The remainder goes to the movie company. Create an application that calculates and displays the following figures for one nights box office business at a theater. Assume the theater keeps 20% of its box office receipts. Use a named constant in your code to represent percentage."
