View 1 RepliesI am trying to export data from textboxes to a blank newly created excel document on button click.
I'm simply taking the string data from textboxes and exporting/saving them to a excel document.
I have a problem with the function below. If anybody knows of a simpler way to accomplish the same results,The problem that I have with this function is that sometimes, not always, it keeps the Excel process running and when this happens I can run the function again until I kill the Excel process manually.
Another problem with this function is that it is slow if the Excel sheet contains a lot of data.
And also I can't get this function to read all the sheets in the Excel workbook and put the contents of each sheet in a separate data table in my dataset.

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.
how to Export DataSet to Multiple Excel Sheets and download those file into a zip in C# asp.net?
View 2 RepliesI am looking for some guidance with the most optimal or efficient way to export a dataset to an excel file. I have searched the forums and found a number of methods to do this. However, the code I am currently using is very inefficient as it is itterating through the rows and columns to create the excel file. The app I am working on needs to be able to create 50 or so excel files each with 500+ rows and 40-50 columns. This method seems to inefficient for my use.
I have seen some code out there to use an ODBC call to excel to create the file. I am wondering if someone can verify that this is the most efficient way to meet my goal. It should also be noted that after the export I will want to do some basic formatting of the sheet. Adding bold column headers, autofilters, and autofit all columns.
I'm facing a problem reading .csv file into datatable. The machine on which i install my window service ( which reads the csv ) is Windows Server 2008 R2.The error i get is : The 'Microsoft.Jet.Oledb.4.0' provider is not registered on the local machine
Below is the code i use to fill the dataset from .csv file :
string connstr = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=" + System.IO.Path.GetDirectoryName(arrFilesName[iCount].ToString()) + ";Extended Properties = 'text;HDR=YES;FMT=Delimited'";
OleDbConnection conn = new OleDbConnection(connstr);
[code]....
I also looked at the other option i.e. Micorosft.Office.Interop.Excel but that also needs Excel installed.So, I would like to know that, is there a way to read a .csv file without having Microsoft Excel install on the machine.
I'm using ODBC to export tables from a dataset to an Excel file without auto-formatting Excel or even needing to have Excel installed on the users PC. This works great but I just had a request to autosize the columns and make the header line bold. The only way I know of doing this is to fully automate Excel to control the row/column/cell formatting. Does anyone know a way of doing this without auto-formatting Excel?

I have data in a DataSet and want to extract 3 fields from each row in the DataSet.
Field1 = String
Field2 = Date
Field3 = Time
I then want to add all the Field1 strings to a combo list box, sorted by the dates and times in Field2 and Field3.
Is there an easy way to get the data from the DataSet in a Sorted order?
i.e. Equivalant to saying "SELECT [Field1] From [Table] ORDER BY [Field2], [Field3]" in SQL.
I'm trying to access the most recent instance of Excel so I can paste data. What works for me is if Excel isn't already opened, I open it and can paste the data where I want to. What isn't working for me is if there are multiple instances of Excel open.
I'll explain: Say I have 3 instances of Excel opened, each with one workbook. Instance 1 = Book1, instance 2 = Book2, and instance 3 = Book3. I want to paste my data to Book3, since that's the most-recently-opened instance. Here's my code:
' Get (array of) all running Excel processes
Dim xlProcesses As Process() = Process.GetProcessesByName("excel")
If xlProcesses.Length = 0 Then ' If Excel isn't found
[Code]....
The AppActivate (line 10) does indeed activate the correct instance of Excel (Book3), but xlApp (line 13) ends up getting assigned to the Book1 instance, and my data ends up pasting there, even though Book3 is the visible/active workbook.
I have 300+ excel files that need to be combined. There are 4 different types and in 4 different directories on my network. I need to copy the data out of each one and combine the data into a new single workbook (1 for each type). I have come up with a solution that does MOST of what it is supposed to do. Only problem is I can't figure out how to have the paste operation go to the same single workbook. No matter what I have tried it opens a new copy of excel to paste into everytime. Here is what I have so far.[code]...

View 1 RepliesI am working in VB.net 2008. I have a Window application that will be used to eliminate a lot of manual copy and paste activates from one work sheet to anther. Workbook 1 (wbMatrix)Never has the same layout twice. The destination Workbook2(wbTemplateSAS)has a defined layout that remains constant. To collect the copy ranges the user pouplates the text box on the form. Only the textbox that need popualted. There are 16 total. These textbox values are then concantianted to create the range. This process is intiated with button click.
When itinated the copy and paste works but not as expected. Cell.text range paste correctly In A9, OEC range paste correctly in P9. After that it skips the next colume as it should. Then in colume R9 the error starts the a paste of the range A10:B10 form wbMatrix is pouplated in R9:S9 Then It paste accoring to the application T9. Then in U9:X9 it paste date for wbMatrix A10:D10. It paste correctly again in Z9. it has the same error agiain till the next Range. It then paste correctly in 9AD. This should be the last paste that have values entered in the textbox to create the range. But it does not finish it paste the balnce of the cells form wbMartix on wbTempateSAS.
To sumerize above
wbMatrix Paste to wbTemplateSAS
First Row =10
Last Row = 158
[code]....
In visual basic code works as below MyWorksheet.Range("A1:D1").Formula = "A1B2"
In excel it shows in
A1 as A1B2
B1 as A1B2
C1 as A1B2
D1 as A1B2
what i want do
A1 as A1B2
B1 as A1B3
C1 as A2B4
D1 as A2B5
