Create Text File From Excel And Know .range?
Jan 11, 2009
I've found ways to read from a .txt file into Excel, but (having created and loaded an Excel sheet via vb.net 2008) I want to do the opposite which is to read each cell and row into a .txt file csv format like this: "Surname","Andrew","2","Mr","Hon.Member","PERCUSSION" I guess I need some way of knowing when the last row of data ends. Once in a .txt file I can load data in a variety of ways into several ListBox/s and labels without loading and reading the original Excel file.

My application is supposed to parse a text file (relatively easy) and create an excel spreadsheet report. Should I write a stand alone VB.NET application that saves the excel file, or should I use VSTO? I am unsure if there are any differences in terms of ease of development, usability issues, API functions available, etc.Are there any other programming languages/interfaces/libraries that will allow me to rapidly develop an involved excel spreadsheet? I am talking about things like functions, graphs, etc.

In VBA I am able to search a text in an excel range like this:
Code:
Workbooks("Book1").Activate
With Worksheets(1).Range("C1:C10000")
[code].....
I have upgraded to Visual Studio because of the jobs I am to carry out. So I am translating all the codes from "VBA" to "VB.NET" (Visual Basic 2008)But I haven't been able to use "Find Method" in VB.NET. I am using Microsoft Office XP Standart Edition (2002 Version). I downloaded and installed Office XP PIAs. After that I referenced them in my project. I used the code Code:Imports Microsoft.Office.Interop.ExcelBut I can't do what I want Now, how can I use "Find Method" in Visual Basic 2008 to find a text in an excel range in one of my workbooks?

I'm trying to copy a Range from Excel and Paste the information in powerpoint in either the HTML or the default format, however, I am having some difficulties. I am able to get the code to work for pasting the Range as an OLE Object but nothing else. The problem with doing this is that having the embedded excel documents in the powerpoint makes the file extremely large and unstable. I just need to be able to paste the information without the embedded information where it is editable (so, not as a bitmap or picture).
With ppt2Slide
Sheets(index2).Activate
Range("CP12:CT" & RangeIndex2).Copy

dynamically get the range of cells in Excel using VS 2005 vb.net. This works oRange = oSheet.Range(oSheet.Cells("A1"), ("U281")).Select, but "U281" will not always be the last cell in the range. So how would I dynamically get the last cell with data in it with the same format as U281.

My objective is to select specific positions in a moving matrix of a fix range with VBA for Excel 2003. The fix range is about 5 or so columns wide and has a few thousand rows. I select a matrix of 5 to 7 rows and same number of columns. I choose a specific position number in this matrix, write that number in another sheet and move on the next matrix just below where I do the same, and this until the last line of the range.
I've tried to write a loop function but this seems to take a lot of execution time.

I am running into trouble converting the ActiveChart.Paste method. I can't get it to work in VB.NET. It either throws an error or It just leaves an empty box when I do it in VB.NET (if I add .chart before the paste it runs, but doesn't paste any values), but in VBA it fills in the values of interest. I have tried creating a chart object, but that did not seem to work either.

I have an excel file with few macros written in VB language..
Now I want to create an installation file that will install this Excel file onto clients machine at a predefined (or user chosen) location just how a normal installation file works.. I also want the user to put a serial code that will be validated (don't know how)..
I think making an installation file in VB.NET is possible. My question is can I make installation file with just an excel in it and the feature of validating serial code using VB.NET?.. If it is possible that would be great.. otherwise what other solutions do I have..

Why are there no examples that I can find on how to import an excel range into SQL Server, there are plenty of example on how to import the whole spreadsheet but none for the range? I find this wierd.
What I need to do is import an excel named range into a sql table using vb.net. I have been able to import the range from excel to access but not to sql server. I used the many examples that are on the web using OLEDB for the connection part and ODBC for the command. However I continually get the cannot find and installable ISAM. I have excel 2003 and Excel 2007 on the box.
I know this can be done using SQL Server SSIS package, which I have used before, however you have to install certian SQL Server features on the box that is running the application for this to work. I want my application to be able to run on any box that it is installed on without the need for the SQL Server features to be installed.

I want to define a range in Excel, but I do NOT want to use "A" or "D" references for columns. I am making a table, and to set it's range I use:
Code:
.Range("A1:D4")
However, at the time i write the code I do not know how many columns will be involved, so I don't know if "D" is the end column. For rows this is fine, as i could write this:
Code:
.Range("A" & i & ":D" & j)
But how do I do this for columns? I really would rather not have to convert my integer number for the end column to text. If I know that the table should go from row 1 to 5 and column 1 to 10, how to I select this range?
