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]...
View 4 RepliesI 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?

I thought it would be fun if I could write vb.net or c# code at runtime and the interpreter would automatically parse it like python does it, so I made a little program, which would do something similar. Basically it looks like this:
InputArgs = Console.ReadLine()
ParseInput(InputArgs.Split(" "))
Private Sub ParseInput(Args as List(Of String), Optional TempArgs as List(Of String))

I know it's not a good system, but it show's the basics. So my question is: Is it possible to make vb.net or c# like python - interpreted at runtime?
I am on a new topic in VB.NET and I am so confused I don't really even know where to start. It is sending Parsed Packets. This packet below is a login server of a game and I want to know how to send it so it automatically does it.[code]....

What i'm trying to do is retrieve 2-3 pieces of information from a parsed html file, then add the data into a listview in the corresponding columns i was initially going to do a function for each piece of information to retrieve but thought maybe i could do it all with 1 function instead.

I have some info in a listbox on another form. I want that information parsed to another form, and I would like to, for how ever many items there are in a listbox, create a button for every item and obviously parse the name to another label. I guess I would do this via an array.
View 2 RepliesI 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 the code and i want to write to the last row in the excel everytime i have new values in the text boxes.me modify the code ?

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.
This is my macro for the Excel userform:

I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}
[code]....
I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.

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 invoke the table similar to as follows:
<%
return_value = make_excel( sql_table, excel_filename)
%>
[Code].....
What I need to be able to do is run through the values in sqlTable above, check their type and then build the sql to write them.
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 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".
