I am creating reports using the Microsoft ReportViewer control.I am encountering some formatting issues when exporting the reports into Excel. The problem is that I am specifying a line width of 1pt in ReportViewer, which is the smallest line possible (or is it?).When the export is done, the line widths in Excel are all thick borders.I am trying to figure out how to get the line widths to be standard lines in Excel.
I have a databound DataGridView, and I'd like to keep one column in front, with a slightly smaller width than the default. The grid's AutoSizeColumnsMode property is set to Fill so that the columns fill out the entire grid. This makes the first column equally large as all others, which is why I need to set its width manually. The smaller column is the first one with the checkboxes. I have two grids that I need to do this with, and for some reason it works just fine with the first grid, but gives a null reference error on the second grid...
Here's the code for the first grid (working fine): vb.net Public Sub UpdateTodoGrid() ' Load todo items todoGrid.DataSource = _TodoManager.LoadAll() ' Set backcolor For Each row As DataGridViewRow In todoGrid.Rows [Code] .....
As you can see, the code is exactly the same (except for not setting the BackColor of each row and not using the ReadOnly property*). When I run this code, it gives me a null reference error ("Object reference not set to an instance of an object.") on the line where I set the column's Width. Obviously 'col' is not Nothing (otherwise it would have errored before that line), and there's nothing else there that could be Nothing... I assume that something happens internally in the grid when you set the width of a column, and that there is a null reference there, but obviously I have no control over that.
The grid's are absolutely the same, as the second grid is just a 'copy' (meaning I copy/pasted it in the designer) of the first. So all their properties are equal. I thought maybe the ReadOnly properties were the problem, but I tried putting them in in the same way and the issue did not go away... The first grid is not ReadOnly (because the checkboxes need to be editable), but all rows except the first are, while the second grid is completely ReadOnly.
I am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method. DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification." Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt" but no success.
For delimited format it is working fine DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt" I have gone through the link [URL] Error message is same as of me but example shown is related to import of txt file.
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 am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.
I got a code that exports datagridview to excel, how can I format the worksheet in excel through coding in vb.net because I have to include a header before the data in the datagridview nd some data that is in my form in vb.net like the values in my labels and textboxes.
I have a stack panel with 10 borders in it. the application performs the following operations: 1) it takes the last border and set its width = 0 2) It remove the border form the last position and it inserts this border in the first position 3) Once is in the first position a double animation increases its width to 50 No it works well for 10 times then it become impossible to set the width of the border to 50, it stay to 0. It looks like when you run a double animation the width property becomes blocked and you can not change it. Is there a way to unblock it?
When I drag a dataset onto a form (as details), is there a way in which the textFields maxLength property is automatically set with the width within the actual table. Or do i have to select each textBox and enter it manually?
I am working with binary files that have 500 rows and 500 columns (width x height). When I load these files into array I set width and height variables to 500 and I was wondering instead of hard-coding like that how I can code in a way that the program should find the # of rows and # of columns of the file before loading the file into array...
Dim sqlString As String = "spExportRateProfile" & Session("OfficeNumber") & "," & Session("SalesRepID") Dim conn As SqlConnection = New SqlConnection(Utils.GetConfigKey("ConnectionStringVimas")) conn.Open()[code]....
What do I need do after this to export my data to excel?
I am trying to export a datagridview ti excel, but i get an error I do not quite understand.I have made two click-events using two buttons looking like this: [code]Button 1 fills the datagridview and in works, but when I get try button two I get an invalid index error pn the line highlighted in red.
I am exporting a datagridveiw to excel, this works fine. As of now there are columns and headers that i needed to add to the excel data that did not exist in the datagridveiw. This also works fine, the data is held in cells a2:f2, now i want to take this data in these columns and filldown to the last filled row of the excel sheet. In this example lets say i have 49 rows of information, i want to take a2:f2 and copy it down to the 49 row of the excel form. Below is the entire code of the export process, i have noted where i need this code to go with , i am not sure if i should just use a for loop, which i have tried to no avail.
I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.
I need to export data from a sql table into an existing excel spreadsheet (not create a new one) in Visual Studio 2008.
Here is the code I am using:
Dim SecFileName As String = "C: est estfile.xlsx"
I get an error saying the external table is not in the correct format. I assume taht means the existing spreadsheet. But I have verified that I have the same number of fields (i.e. columns) as the spreadsheet I am inserting the data into.
I need the code for exporting the content of aspx report(which is a static page without any html components butcontains css style) to excel sheet without using any asp.net components like datagrid or any other.I need the complete
i need to export a query result to excel. I did it using a few methods but it seems that it is taking to long if loading large amount of data like 1000 rows. I did looping a datatable and write the values to excel via excel object 11.0. - 20 secs for 1000 rows exporting the data to CVS but i will have problems formatting the data. using copyfromrecordset using adodb. But they want it to be done in .net Are there any better and faster ways? Must be done programmatically using vb.net.
I am using the written below code for exporting datagrid view to excel . My DatagridView has 17 columns and 2000 rows . The code i am using takes a very long time for exporting data . Is there any other way to do it fast.

I'm exporting datagridview data to Excel via dataset.Col 1 of my datagridview contains dates and the grid shows the dates w/o time.Once exported the dates to Excel, they are then formatted via wSheet.Range("B:B").NumberFormat = "ddMM"..The above code works fine for dates having a single digit day. For days 10 and above, the dates are shown as dd/MM/yyyy 00:00 in the excel sheet.[code]If days are single digit, month is swapped with day when writing to Excel from a dataset.
I have been trying to export a DataTable to an excel file and have been hitting a few wallsI am using Visual Studio 2010, VB.Net, Windows 7 64-bit, Office 2010 32-bit. 1) I first had trouble with not closing the Excel.exe *32 process and solved that by using the FinalReleaseComObject(ExcelFile).2) When I use the FinalReleaseComObject, it re-checks the "Ignore other applications that use Dynamic Data Exchange" under Excel's Options-->Advanced. Then any time I try to double-click on an Excel file, I get the error: "There was a problem sending the command to the program." Excel opens, but the worksheet I want does not. The only solution I have found to this problem is to have the DDE unchecked
Private Sub PrintTable(ByVal data As DataTable, ByVal FileName As String) Try Dim priorSum As Integer = 0
but nothing prints. The app exports to pdf works in test, but not when I move it to production. I have to remote into the machine that runs the app, so my printers from my local pc are "attched" to the remote session, can this have something to do with no output. The remote machine does not have the Adobe print drivers installed.
i have a dgv populated from a csv file and i am filtering the dgv further and exporting it to the excel. But my problem is it is exporting all the values from the original dgv not from the filtered dgv. I am using one dgv and 2 buttons in my form. When I click the button 1 my dgv gets filtered . when i click the button 2 it must export the filterd dgv to excel but it is not in a way as it is supposed to be instead it exports the unfilterd dgv (all the values from the dgv)
I am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.
My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.
My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.
