External Table Is Not In The Expected Format
Oct 12, 2009
I have a problem with open connection to Excel file. I use this open connection:
[Code]....
I use Excel 2007 to open the file and there is an error message "The file you are trying to open is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file." I don't know what is wrong with my code to create and save data to excel file ?? Or maybe something is wrong with my open connection?

I have a program that is connecting to an Excel file using ADO.Net. It processes some html files and parses out certain pieces of data and enters it into the spreadsheet (either updating the record with recent data if the record already exists, or adding a new record if not). It seems like it works fine and I can process several html files successfully. But every once in a while the program will crash with the error that the "External Table not in Expected Format". When this happens, all I have to do is exit out of my program, open up the spreadsheet file in Excel, save the file, close Excel, and restart my program. Then I am able to continue processing files including the file that I was trying to parse when the program crashed.
The Spreadsheet is in Excel 2003 format, but I am using Office 2010, however when I am saving the spreadsheet I never get any boxes popping up about possible compatibility issues. I also don't have to do anything to the spreadsheet when I've opened it in Excel expect to resave it. Not sure if anyone has heard of this issue before or how I could possibly fix it.... If anyone needs code, I can post it, although because my program seems to function correctly most of the time, I don't think that there is an error there...

Program : my game is a frogger port, you make the frog cross the road until you run out of lives. When you die, you are asked to enter your name and the name is appended to the end of file called names.txt, the final score is appended to the end of a file called scores.txt.Using the System.IO functions, i read the contents of each text file, and load the contents into two separate strings (one for names, one for scores. These two long strings are then broken down using Split() command, transferring the pieces into an array. (again 2 arrays - one for names, one for scores). The contents of both arrays are then loaded into 2 listboxes, 1 for scores, 1 for names.
Problem: i can sucessfully load the contents of both files, and display them side by side - but i want to re-arrange the scores so that they are in descending order. While doing this, i need to make sure that the player name matches up with the score - so the order of the names being displayed would have to be changed aswell. After spending many, many hours trying to do it myself i have had to give up - i'm clueless. My first issue is converting the score array into integers so that the array could be sorted, the second problem is then sorting the names so that the scores and names match up.

It's probably a long shot, but is there an add-in for VS2010 that can change VS2010's default formatting rules? In particular, I'd like to format similar lines so that the commas line up vertically, creating a tabular look. If it could line up equal signs, that'd be better still.In this case, I'm populating a dictionary with methods to translate a flat file into an object.
Parsers = New Dictionary(Of String, Action(Of String))()
This is a pain to read:
Parsers.Add("Aircraft Make and Model", Sub(value) Aircraft.Name = value)
Parsers.Add("Words/Frame", Sub(value) Aircraft.WordsPerSubframe = Integer.Parse(value))
Parsers.Add("Bits/Word", Sub(value) Aircraft.BitsPerWord = Integer.Parse(value))[code]......

Dim StatusClosed As String = Form11.Closed_Code.Text ' usually = S or ClosedSale or Closed Sale
Dim SubjId As String = Form10.add_Num_txt.Text ' usually = StreetName or Street Name or SN[code]....
If SubjId is StreetNumber or SN its ok , if its Street Number with the space I get error
If I place a ' around {3} in my afilter line then it works if the SubjId is Street Number but not StreetNumber or SN

First I tried getting a SQL query into an array, and then mail it. Made the data incomprehendable. So someone told me to use CSS to build a table format, filling it with the array. A LOT of hard work (since I had to learn css all the way from "what is a css".
Then I was told "Array? why use array when DATATABLES are soooo much easier"
So here we go again. "What is a datatable, and how does it work"

I am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method.
DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"
I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.

I am trying to make my program print out a requistion slip but I don't want to make a report using VB b/c sometimes the printer is not connected and it is better to have a Microsoft Word document and save it as such. So how do I create a Word application from VB? I basically am going to set out a format, make a small table etc. and then whatever the user types in the textbox, it will appear in the slip. (I am using Word 2003)

I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?
