Opening An Excel 2003 File Then Searching That Open File For Data
May 22, 2012
I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source='" + fileName + "'; Extended Properties=Excel 5.0" Dim ExcelConnection As System.Data.OleDb.OleDbConnection ExcelConnection = New System.Data.OleDb.OleDbConnection(ConnectionString)
Error occurs on line ExcelConnection.Open()External table is not in the expected format.
I have this program that uses OLEDB connection to open the excel file, and imports it's data. Then I use mysql connection to inserts all this data. Now my question is, is it possible that I can use mysql connection in opening the excel file, or only OLEDB connection is the most possible way to open it?
When importing data from excel to vb.net desktop application, Im having "file is open" error. Excel file is at the remote pc. Excel file must open and I have to reach anytime. How can I handle this problem?
I´m working in a application where I receive a .htm file, but I need convert it to a excel 2003 file

I am trying to open an excel file and write to it as data becomes availableI can create an instance of excel and write to the selected worksheet once. But, I can't seem to write back to the existing file. I keep on getting a null reference error when I try to send new data to the file.The function I am using will run once, but when it returns to the main form, I lose the values of xlApp and xlWorksheet. It appears that going in to the function makes the original values null.
I 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
I need to open a file everyday which is located in the V drive However the file renames itself daily such as DAA123 DAA128 So I cannot do a Data Refresh What I need to do is create a Macro to search the text document and if it prices PRICES365 and as at todays date Then it opens?
i'm trying to save an excel file after I open my excel application. This is what I have so far:

[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!
The first thing to do is to browse the excel file in my vb.net program then read the content of excel file and display the value of excel content in listview.
My company is currently using a Linux/Powerterm program that exports reports via email on a daily basis. I have a add-in program installed on outlook to automatically save the report to a folder on the server. The file that is exported appears to be an XLS 97-2003 Worksheet, but I confirmed from the original programmer that this file is not a true Excel file, I believe it is a unicode file, but it can be opened by Excel. I want to link these files to an Access database within my form, but Access does not recognize this file format.I attempted to create several programs in Studio to convert the file to an XLSX file, but on each attempt I receive an error the file is an in unrecognizable format which is killing me at the moment. I even made attempts to dump the data to an dgv but it still wont be accepted.
how to open an excel 2003 file in VS2008,what i want is to open an excel file there is only one sheet in it and 4 columns of data to read row by row and change certain values. that's it.
The following gives me an error when I try to open an Excel file if the value of lblFileName is different than the file on disk by differences of upper or lowercase letters.
Dim excel As New Microsoft.Office.Interop.Excel.Application() Dim wb As Microsoft.Office.Interop.Excel.Workbook = excel.Workbooks.Open(txtFileLocations.Lines(w)) Dim ws As Microsoft.Office.Interop.Excel.Worksheet = TryCast(excel.ActiveSheet, Microsoft.Office.Interop.Excel.Worksheet)
when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

I'm trying to open an Excel file to get and set some values. Unfortunately, I have no choice, I must to work with Excel.
Dim xAp As New Microsoft.Office.Interop.Excel.Application Dim xWkb As Microsoft.Office.Interop.Excel.Workbook
xWkb = xAp.Workbooks.Open("c:uploads este.xls")
Always I have this exception: (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))
Need I Excel installed in server machine to open Excel files? I don't think so, because when I create a new application and workbook throught code, all things go right, but... its a possibility...
I would like to be able to have my users open an Excel file and include their add-ins they have installed and usually show up when Excel normally starts. Using this code, Excel opens with no add-ins visible:
vb.net Dim excel As Microsoft.Office.Interop.Excel.Application
Dim wb As Microsoft.Office.Interop.Excel.Workbook Try excel = New Microsoft.Office.Interop.Excel.Application wb = excel.Workbooks.Open(filelocation & "checks.xls") excel.Visible = True
[Code]...
Is there a property to allow add-ins when opening an Excel file?
I have a windows form and I am attempting to create an excel file from a datatable that has already been created and i'm hitting a snag - the error is: The ':' character, hexadecimal value 0x3A, cannot be included in a name."I have a button to start the Export process, here's the
'here's all my imports for the form Imports DocumentFormat.OpenXml.Packaging Imports System.Text
i would like to do FILE I/O without a dialogue. the file always be the same and the location will always be the same, therefore i dont need a dialogue. i would like to know how can i do this? what is the code to open, write, and save to a file without the dialogue.
I am have an exception when I run the following code :
Private Sub MainMenuForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Try 'Save the Sum of the Existing "Excel" Processes: For Each Proc As Process In Process.GetProcessesByName("excel")
I'm using VB Microsoft Visual Studio to try to open an excel file, clean a column of data, then load into a datatable for use by program (enter Excel data into Reflections, process / screenscrape, enter data into Access db).
I can load the data into a datatable just fine, but I'm having problems figuring out how to open the excel file BEFORE it's loaded into the datatable so I can "Clean" a column of data the program reads from that can potentially have hidden characters. Below is what I have so far.
Sub SelectnLoadExcelFile(ByRef errFlag) dt.Clear() errFlag = False
I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.
I would like to open the excel file after create the excel file. The creating file function is done, but the system unable to open the excel file. My coding as below:
Dim xlApp As Excel.Application Dim xlWorkBook As Excel.Workbook Dim misValue As Object = System.Reflection.Missing.Value
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.
