I am tring to insert a row or shift all the row down one; depending how you want ot look at it. In oter words I have data in rows one through 10 and I want to move it down so that I can put a headings in row one.In Excel VBA I would do something like:Rows("1:1").SelectSelection.Insert Shift:=xlDownBut you can not use exactly this code in VB.Net and I cannot figure out how to do it here.Here is code that I used, succsessfuly to widing a cell:Code: rng = xlsSheet.Application.Range("D:D") rng.ColumnWidth = 17.0
Is there any way to insert an existing macro into a existing excel file without using the excel library ? I need this to set the excel to print whole work book .I cannot use excel library because it will be done online in the server where installation of excel is not possible. I can however use the c#.net coding . I am using NPOI to generate the excel.
the macro is given below
Private Sub Workbook_BeforePrint(Cancel As Boolean) If printed = False Then Cancel = True
I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
I want to encapsulate the use of Excel Interop to make it easier to use somehow in a reuseable library.So far, I have written some tests that work good altogether, except that between each test, I force Excel to quite so that it does have handle on the test file no more in order to be able to delete.Once I quit the application instance between after each of my tests, Excel seems to be no longer responding, causing Windows to display "Excel has stopped working and is looking for a solution"
message. This message lasts a few seconds, meanwhile Excel is closing, causing the hang on the file to occur and my tests to throw an exception like "Cannot access file because it is being used by another process..."
i'm trying to save an excel file after I open my excel application. This is what I have so far:
'Opens the report xlPeakDemand.Visible = True xlPeakDemandWorkbook.SaveAs("C:Documents and
[Code].....
When saving as an xls it works fine but when saving as a htm its a disaster Just a bunch or symbols and stuff. BUT if I go into my xls document and Save As webpage from there, it works fine!
This is my code to add a row to an excel file: Public Sub Add_Records() '========================================================================== ' Run an INSERT INTO command to add new records to the workbook. '========================================================================== Dim Variable As String Variable = "15000" Dim conn1 As New System.Data.OleDb.OleDbConnection(m_sConn1) [Code] ..... It works fine as long as the variable Variable is a number. If I make it a string it doesnt work.
I am taking a pre-existing excel spreadsheet and inserting a blank row at the top. This part works, the part I am having problem is the fact that based on the code I have, I have to open the spreadsheet so when you execute the code the spreadsheet opens. Then when done, close it. When I try to close it wants me to save the document, even if I call the save method. This whole process should happen behind the scenes so I really don't want the spreadsheet opening.
See code below. moApp.Visible = True oWB = moApp.Workbooks.Open("I: estcsv.xls") oWB.Sheets("testcsv").Rows("1:1").Select() moApp.Selection.insert(xl.XlDirection.xlDown) oWB.Save() oWB.Close() 'When call the close, it still asks me to save the spreadsheet even though I called oWB.Save above.
how I can use excel 2003 and excel 2007 on my application. I add a reference to Excel 12.0 Object but this one is not compatible with Excel 2007 and i think if i add Excel 11 Object it will not run on excel 2007.
Is there any solution that I can use so that my project can be used with either excel 2003 and 2007?
i am generation a excel sheet from vb.net and have a question on inserting a forumla from vb.net into an excel sheet.
I am creating this sheet out of vb.net but with a statement like this:
worksheet.cells (1,10) = "myvalue"
For my formula i need the read cellnam like "A1". But i have only the value cells (x,y). How can i get the real cellname for my formula or how am i able to insert a formula with the given information (cells(1,1))?
I'm using Visual Studio 2010 (VB.Net) and Open XML SDK 2.0. How do you insert a formula into an Excel 2010 worksheet? When I do this I also wish to set the CellValue property of the cell to a DBNull or EmptyString to force Excel to recalculate the cell when the user opens the workbok.
OVERVIEW:I am currently having an issue loading a large number of rows into Excel. I say large because the attached code in fact correctly inserts 50 rows into an Excel worksheet, however, as the number of rows increases to no more than500 rows the data is not inserted into the worksheet. No error is thrown by .net and the .xls filesize actually shows an increase in size, however, when the file is opened there are no rows in the spreadsheet..... Then, when the .xls file is closed the filesize is once again reduced.
Again, the code works for a small number of rows. Are there any known bugs with the OleDB driver for Excel?ADDITIONAL THOUGHTS:I have tried inserting rows to both Excel 2003 and 2007, same issue.I have tried closing the connection after each insert.... performance if horrible and it does not fix the problem.I have wrapped the ExecuteNonQuery in a transaction.... no go....
But as soon as I change any of the numbers to doubles (e.g. 23.32457) I get a crash (it doesnt crash on the insert, it crashes on the next one:)The INSERT INTO statement contains the following unknown field name: '23#2345'. Make sure you have typed the name correctly, and try the operation again.
I have this piece of code which picks the data in an excel file. At the moment i have the data into the dt table. how do i write the data in dt to FECHO_UNICRE table at the UTLT.accdb database? I want to fill the table just after deleting the existing records.

I need to import data from Excel into a MySQL 5 database. The format of the column in excel is set to "Time". the field value looks something like this:
17:20:00 If I do this in my vb.net
strTimeIn1 = Trim(jobdt.Rows(j).Item(7).ToString)
I get this in my Immediate window when debugging:
"12/30/1899 4:10:00 PM"
what's the correct way to convert that string to a time value so I can insert into a datetime field in my database with no issues.
what to do as i used Openrowset but it didnot works well the sheet contain variable no of columns.
Dim sConnectionString1 As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & exfname & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"""[code]...
This works well when having about 240 columns, but if it exceed to 256 it gives error and the connection would not get open.So i decided to use bulk insert into a temp table,how to bulk insert from specific sheet of workbook I have tried
select * into test1 from ( select * from OpenRowset( 'Microsoft.Jet.OLEDB.4.0',[code]....
But it didnot works when number of columns exceed but works well on sql when columns are less.
I have a VB.NET application that creates a dataview from sql table and exports it as an excel file. Now, the data is inserted value by value. Instead, I want to insert the data from the dataview as a bulk insert on to the excel file. The data insert should happen from the third row, as I need to use the first two rows for column insert and data formating (which is done later in the program using excel macro.).Heres the code I wish to upgrade :
Dim strConn As String = "Data Source = LV-SQL2; Initial Catalog = TC_MASTER; user id = SQL2JOB; password = ******** " Dim strSql1 As String = "Select Customer_id_1, file_name from customer_list_DA order by customer_id_1" Dim da1 As New SqlDataAdapter(strSql1, strConn)
I am writing a report to an excel template and am trying to insert a page break into the report. Part of my code is included:
Imports msWE = Microsoft.Office.Interop
Dim Rnge As msWE.Excel.Range = excelApp.Range("A20:M20") Dim excelApp As New msWE.Excel.ApplicationClass
excelApp.Worksheets.HPageBreaks.Add(Rnge)
Now the pagebreak code executes but it does nothing. Its almost as if it is being ignored. Also I have heard that using Microsoft.Office.Interop is not a good idea as it is slow and unstable.
how to write the AT command in the serial port. I have connect a modem to the comport. I have this code that I get from my teacher. But it does not show any AT command in the code

What i am trying to do is to have a fixed initial row heigh of 60. Then the user is to put Data into the empty fields. When it user clicks the add button it will loop until it reaches an empty record and then it will insert the data into a SQL Database. Its simular to my code below but with a DataGrid. Also, this DataGrid is located on a ControlTab. The code below is just to show the logic of what i am trying to do.
