I currently have a bunch of numbers separated by tabs saved in a text file. Is there an easy way to copy the information from that file into .xls file and add additional information (like row and column names). I need the information to be in a report format. I am not sure the best way to go about doing this.
View 12 RepliesIm looking to set up a VB.Net application that allows me automatically import files from Excel into an Access Database. Can anyone point me in the right direction? I will be importing files regularly so I would like to make an application to simplify the process. Would I be better off creating a Macro that I can reuse in Access or a VBA or?

I have a psychology experiment that has users respond to specific text or pictures by pressing either a button for "similar" or a button for "opposite" and then the program records the time from the presentation of the stimuli to the time they press one of the buttons as the latency. I have the information ans some other data successfully exporting to a text document but would like to have just the latency data also go into an excel spreadsheet for easier analysis.

I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
I created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.

These are two code blocks from the two programs I have wrote. The first is the server program that receives a connection and writes the file to disk. The second is the Client program that sends the file to the server to be written to disk.As it is - it hangs. I did once get it to write to the disk - but the file was twice the size of the original. what objects to use for transferring a file over a TCP IP network connection with TCPClient and TCPListener.
I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
View 1 RepliesI have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
This should be very simple but I'm very new to Visual Studio so I can't get it to work. I want to take data from an excel (2003) file and turn it into a bunch of charts that would be viewable on a webpage that I'm trying to build in Visual Studio .Net 2005 professional.
I can't seem to use an excel file as my data source, here are the steps that I've followed:
1) created a new asp.net project
2) dragged a report viewer from the toolbox and it asks me to choose a report or "Design New Report."
3) Clicked Design New Report, and it opened up a new blank report.
4) Clicked "Add New Data Source" and got the Table Adapter Configuration Wizard.
5) Clicked new connection and it brought up the Add connection table.
6) Clicked "change" under data source and I chose Microsoft ODBC Data Source (not sure if that's right.)
7) Under "Data source specification" I chose "Excel Files"
- The first time I did this it brought up a window for me to choose an excel file so I did. Something along the way failed out but it stilled saved "ConnectionString1" as a connection to that first excel file. Now every time after I choose "Excel Files" and click "OK" the add connection window disappears and it goes back to the Table Adapter Configuration Wizard with the "ConnectionString1" as the connection string. It won't let me specify any different excel file. So I did 1-6 again and picked up at 7B
7B) Instead of using "Use user or system data source name:" I chose "Use connection string:" and clicked Build.
8) Picked the "Machine Data Source" tab and chose "Excel Files" and clicked ok
9) The "Select Workbook" window appears so I went to the file I wanted to use as my data source and click OK
10) Back on the Add Connection window I clicked test connection and it succeeded so I clicked ok.
11) It goes back to the Table Adapter Config Wiz window, but the connection string only says "Dsn=Excel Files"
12) clicked Next, then Next again, then clicked on Query Builder. The Add Table window pops up but there is nothing in there for me to choose from.I've tried a million other things, here are a few of the errors that I seem to get a lot.
