Export An Image Into An Excel File Without Excel Installed?
Oct 7, 2011
I need to export Chart(image) and grid (tabular) row data into excel file. I can not use automation because Office tools are not installed in my server. I've found a bunch of free/proprietary tools like:
I am building a windows form application using visual basic (visual studio 2008). The idea is to query a MySQL DB and export the results to an excel document. I managed to do this using this code (I will just show the export to excel part):
And it works fine on my laptop (which has office 2003 installed), but when I create the setup package and install it on the server where I am going to use it (which does not have office installed), I get this error: "Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154." And for the record, I need the excel file, not a CSV.
I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient. Right now I do not know if the target machines have excel installed but I know with certainty that if they do it would be 2010, is there any method or library that allows you frame your own form around an excel window?
I am uploading an excel file to my app and want to read it. Do I need to have excel loaded to read this?I am getting an error of Object reference not set to an instance of an object.
Public Function GetExcelData(ByVal ExcelFilePath As String) As DataTable Try Dim OledbConnectionString As String = String.Empty
I am building a windows form application using visual basic (visual studio 2008).The idea is to query a MySQL DB and export the results to an excel document.I managed to do this using this code (I will just show the export to excel part):
I tried to read excel file using the method i found here [URL] But i get an error on ADODB.Connection saying "Type 'ADODB.Connection' is not defined" in the following code:
Code: Private Function GetExcelConnection(ByVal Path As String, _ Optional ByVal Headers As Boolean = True) As Connection Dim strConn As String
[Code]....
Its was used in VB6... do i need to do something special in Visual Studio 2010?
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.
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 have read some of the other posts on this and seem to be a little different than my situation. Trying to print out some reports into an excel document on the clients machine - of course it works fine on my local (heard that before right). I went in and set my references Ms.Office.Core and Ms.Office.Interop.Excel to 'Copy Local' = True so the .dll are in the servers bin folder.
i built a patient management software for a clinic and i need to export patiet list from ASP.net grid view to excel file my question is:Is there a way to export gridview to excel i am using vb.net and visual web developer 2010 i store datasource from advanced search page into a session and redirect to result page here is the code of result page
I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?
I'm trying to export a datagridview to Excel and open the Excel spreadsheet (not SAVE the worksheet).
Public Sub ExcelRpt(ByVal DgvName As GridView, ByVal url As String) Dim xlApp As Microsoft.Office.Interop.Excel.Application Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

I have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..
I need some easy/basic way to export DataGrid to Excel file and also to be able later to Import this file back to DataGrid. Nothing complicated its simple table with values amount of columns won't change.
So I load some excel data into a LB and can manipulate it, at this point I want to export the data back into excel and do so with the following button:
Public Sub Button4_click(ByVal sender As Object, e As System.EventArgs) Handles Button4.Click ListBox1.Sorted = True
I need to read a .txt file and then put that into fields in an excel spreadsheet. for example i get print spool files that have invoices on them i need to put the customer names into a column of customer names and their addresses into a column of addresses. here is what i wrote to read with:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim reader As New System.IO.StreamReader(TextBox1.Text)

Below is the code i use to fill the dataset from .csv file :
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 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
