I am having problems reading an Excel file using ADODB.connection.[code]I do NOT get the error if I have my Excel file open at the time. Does the Excel file have to be open for this type of connection to work?

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...

View 19 RepliesProgram : 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.

I am not sure of the command for format the Table 'Revenue' column for currency. Also is there a way to do calculations? I need to multiply the value by -1?
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.

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"
