I made a userform that allows the person to enter entries in the excel spreadsheet. Everytime that the person clicks on "Submit" button, the entry is added on a new row in the excel spread sheet. That works perfectly fine. Now, I would like to also have a XML file in C: to record whatever the person enters in the userform. I know how to do it in C#, but not VBA. My workplace has access to Excell VBA only.
I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?
i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).

I have imported a sheet from Excel. It grabs the first row as the column names saves it in a dataset, and displays it in a grid view. here is my code to do so:
Try 'Dim MyConnection As System.Data.OleDb.OleDbConnection Dim DtSet As System.Data.DataSet Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The gridview is editable, so when the user edits a cell I want to have a button so they can save the new values back to the excel sheet.
The code above cant be that dissimilar for writing from a dataset instead of reading to, but cant work it out.I want to keep the same Column headings.
I have a simple stop watch application. with start, stop and reset buttons. The timer is displayed in a text box.When I stop the timer I want to be able to write the timer figure to an excel spreadsheet. I need to have the following columns in the spreadsheet, No, Date, Time (Timer figure from app). obviously writing the data onto the next available row each time.
I need to create an excel file from scratch in VB.NET given a DataTable from asp.net. I can do this for a specific file, but I don't know how to do it for a general database. That is, where I use the "CREATE TABLE ..." I don't know how to tell it what types to use for the data in the table.
The DataTable is derived from a FoxPro database. (I don't know if that matters.)
I need some code which checks if excel is open or not, if excel is not open then opens it (that code is fine) else try to write some content/cellvalues to the already opened excel, basically I am creating windows application, which has been scheduled to run numbers of time in a day, when ever application executed, the application has something to write to the excel. one more thing is i don't want excel to save and close every time i execute the application, Its like transparent processing of EXCEL writing, a file is already opened, just write some content, and after writing it exit the application without either closing or saving the excel
I am trying to write data to an excel spreadsheet. Simply just todays date and the value of textbox1. I can successfully write it to excel, but how do I get it so each time the application runs it writes the data to the next available row?? I know there must be some loop involved but am having trouble with the coding..
I have an excel database with one column and thousands of rows of "number" data. I need to import the data into my form read the first entry, run an algorithm then move the result to the second column then move to the second entry and so on. I am having issues with where to begin. I am able to convert the excel database to a text file if it makes it easier.The algorithm that needs to be ran consists of reading each character one at a time and is as follows:ENTRY example: 12358458754The characters 1,3,8,5,7,4 need to be summed then multiplied by 3. These are all the characters starting with the first one and skipping every other one. I will call them "odds" (not referring to numeric value)The characters that are skipped, I will call them "evens", need to be summed together then added to the result of "odds".
I am currently using a timer to sample data that is coming in from a microcontroller. I would like to take this data and write it to an excel file. Each sample should have its own line.[code]...

Is there any way to print a message to the console from an Excel vba macro? I have a small VB .NET console application that calls an excel macro, and I'd like the error messages from the macro code to print to the console.
I use a code like this which perfectly works and creates MS Excel files so I can create Excel files and save my data into it.I also use a similar code to read the data, however, it only read and writes Excel 97-2003 files, and does not support Excel 2007 file format![code]...

I am reading an excel file. When everything passes the edits, it is then written to a database. However, if any cell in the row fails an edit, I would like to write a new worksheet (called Errors) containing all of the information from the row which failed.
I am writing a function to export data to Excel using the Office Interop in VB .NET. I am currently writing the cells directly using the Excel worksheet's Cells() method:
I have done some code to write to Excel from a String Array of 3 items. These 3 items are written to columns 1, 2, 17 or 3, 4, 17, depending on the value of the 3rd item in the array. For certain Excel files, this is taking too long to write. Is it because I'm writing cell by cell? Is there any other way of writing faster to Excel?
