Export Query To Excel (can't Translate VB6 Code To .NET)
Nov 1, 2009
I have this working on VB6 that saves a query in a excel sheet:
[Code]...
The XLSNombre is a variable with the name of the excel file that has been set before. The connection I have in .NET is to SQL server (but is the same). How can I use this code (or..how can I make this code work for .NET) or what is the equivalent of this for .NET? I found some solutions but with inserts of single rows or I have to set the title of the columns, I dont find any "simple" solution to do an "insert into" (like the code I use in VB6).
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 have a query being created using oledb from access and need to get the information to an already existing excel spread sheet. I am using VS 2010 with vb.net, access and excel are 2010. I have been running in circles for the last two days and cannot figure out how to get the data from a datareader into excel. This is a vb.net console app, so no web tables or grids can be used.
Dim conn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:PureshowPureshow.mdb;") Dim cmd As New OleDb.OleDbCommand("SELECT PWTC08.Lot AS LotID, PWTC08.Reg AS OfficialID FROM ((PWTC08 INNER JOIN SWTC08 ON cint(LEFT(PWTC08.Lot,
[Code]....
I am almost to the point of just outputting to a CSV and telling the user to import into excel each time. I can export to excel if I put it in a webform, but I cannot figure out how to do using a console app.
I wont to export query results from Access to Excel.From my Access app i execute this function
Public Sub qExcel(pQuery As String) DoCmd.Hourglass True Dim dbs As ADODB.Connection[code]......
Everything is OK when I run this function for the first time. But when I try to run it the second time I get method range of object _global failed error.Also I've noticed that first execution creates excel process that is in my process list even after I close excel. Second execution creates second process and after error when I close excel both processes are gone.Third execution creates no error fourth creates errors .... and so on
I'm running into a bit of a roadblock here. I have tried to search the web/forums for answer for last several hours to no avail and I'm not the expert VB Programmer.However, I was able to write an app to do the following:
1) read Outlook emails for particular emails containing xml link in which I was able to download the file and save to my hard drive.
2) opened the Excel spreadsheet to run the macro which import those XMLs into existing XLS spreadsheets to refresh the data.
3) Those XLS spreadsheets are linked in my MS Access in which I join all four XLS sheets to create one report via Query which I have created in the past prior to this app development.
I have manually done a File Export of this query via ALT+F then E and what I'd like to do is to either take control of menu commands OR alternate method of performing a File Export to a new Excel spreadsheet (version 2003).I've seen two different methods, one via DoCmd OutputtoFile and another is TransferSpreadsheet.Here's my Access coding I have in my VB 2010:
Imports Microsoft.Office.Interop Public Class OutlookOfflineEmailExtractor Dim wsAccessApp As Access.Application
I have been changing my existing code over the past week and have not successfully been able to export to excel in the format that the users are request. I am new to this job, learning vb through training videos, and have been given the task to update problematic old code and interfaces.The users cannot export large amounts of data. They receive a runtime error. The users do not want the export to html.The users do not want the controls to be exported.
I am exporting an aspx repeater control to excel, but in addition to exporting the data in the repeater I am also getting all of the html code. I want only the data, what am I missing?
Heres the snippet of code.
Private Sub submitxcl(ByVal Sender As Object, ByVal E As EventArgs) If Sender.ID = "xcelBtn" Then Dim fName = "ChargeAndSavingsForReportingPeriod_" & Replace(Trim(frdt.Text), "/", "-") & "_Thru_" & Replace(Trim(todt.Text), "/", "-") & ".xls"
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 have found the following code which can get the harddisk no in VB6.0.I would like to translate it into vb.net code.I have tried the auto upgrade function in vb2005 and translated the following code to vb.net, but the outcome did not run probably.Can anyone give me some help to translate the following VB6.0 code into vb.net code?
I need to translate line 4 in the code snippet below into VB. For some reason I cannot get this done tonight. I am either too tired or having a brain drain.[code]
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 a hashing method whose operations depend on input to the function. Profiling the program has shown that too much time is spent evaluating this hash method. I want to try changing it into an expression tree, so the inner loop checks can be done once.
Here is a simplified version of the function (I undid some obvious optimizations for the example, and took out any input validation):
Private Function Checksum(ByVal inputValues As IEnumerable(Of UInt32), ByVal declarations As IEnumerable(Of String), ByVal statements As IEnumerable(Of String)) As UInt32 Dim variables = New Dictionary(Of Char, UInt32)
[code]....
I want to create a function which takes the declarations and statements and outputs a specialized expression tree representing a function which takes an IEnumerable of UInt32 and returns a UInt32.Follow-Up:I succeeded, and the speed-up was ridiculous (an order of magnitude). The main things I had to learn where:Use Expression.Lambda and Expression.Compile to get a delegate you can actually use.The Expression.Block factory method has a 'variables' parameter you (essentially) use to declare locals.Expression.lambda has 'parameters'.If you call Expression.Parameter twice, you're dealing with two different variables (even if their name is the same)! Store the result for later usage. Same for labels, etc.The result of a BlockExpression is the last expression in the block.
I have a line of C# code and can't translate it correctly. 'myString' is a string and 'a' and 'k' are both UInt:a += (uint)(myString[k + 0] + (myString[k + 1] << 8) + (myString[k + 2] << 16) + (myString[k + 3] << 24)); Translators for VB suggest the following but I get "Operator '<<' is not defined for types 'Char' and 'Integer': a += CUInt(myString(k + 0) + (myString(k + 1) << 8) + (myString(k + 2) << 16) + (myString(k + 3) << 24))
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 came accross the code below in a book. I prefer displaying my data in Winforms instead of the Console which the boook uses but I have little understanding of console codes and how to convert them to Winforms.[code]....
