Use Query String In An Excel Hyperlink To ASP.Net Web Application?
Aug 19, 2009
I want to pass some data between an existing excel application and an existing ASP.Net VB Webforms application.
I thought a hyperlink with some query string variables would be the most straightforward means of doing this. However, it seems that the hyperlink does not retain the session of the logged in user.
Testing this with the same URL on a webpage does work. So it seems Excel is starting a new session. Any ideas on how to make Excel hyperlinks behave the same way a browser hyperlink does?
First one is a table with results populated from the sql server backend. The first holds the "FirstName". I want this to have a hyperlink, so when i click on this, it should goto the second aspx page and show all the data in sql server for that "Firstname". the data is in 3 other tables based on firstname, which is phone, address and hobbies.So -
FirstName Samuel --> clicked on it redirect to second page -
Samuel -
Phone Address Hobbies 3104445656 123 main st Climbing
if i need a querystring or is there another solution (better solution). Also how do i capture the querystring in second page?
I have an excel sheet where one column consist of comma seprated hyperlinks. However, I am unable to see a way to insert more that one hyperlinks in an excel cell. Is there a workaeround this?
I am trying to hide Hyperlink visibility in Repeater if there isn't any Text value in Hyperlink. Something like this:
Protected Sub rptReferenca_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptReferenca.ItemDataBound Dim lnkThumb As HyperLink = CType(rptReferenca.FindControl("lnkThumb"), HyperLink)
As a follow up to my previous question Putting together a tricky SQL query
since I now have the records returned as URL format, how can I display those as hyperlinks in my gridview? (this is how the client wants it done, not much I can say to change their mind)
My vb code is:
Dim pds As PagedDataSource = New PagedDataSource() GridView1.DataSource = pds GridView1.DataBind()
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 am trying to write a small application that simply monitors my web site watching for specific hyperlink text to appear. I have been searching around and trying different approaches for a few days and have to accept defeat on this.Basically I need to be able to type in part of a hyperlink or the actual text of the hyperlink into a textbox to be watched for. When it is seen it opens the link in a new window.

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 currently making an app that needs to run a query between two dates. this app will run automatically, so i need to put the dates as today and yesterday, essentially.
i'm trying to save an excel file after I open my excel application. This is what I have so far:

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!
I have a SQL query that I want to integrate into a VBA subroutine in Excel. I have had some success using the Macro Recorder to call up the SQL query (throuh Microsoft Query) in the past. However, the SQL code that I have for this query is significantly larger than previous attempts.When I record this one through the Macro Recorder is trips up because there are too many line breaks integrated into the recorded code. To get around this I have tried to manually update previous (successful) queries with the larger SQL code that I want to use, but without success.I was hoping that someone out there has some experience in integrating the standard SQL query code (SELECT xxxx, yyyy, zzzz, *nnnn FROM aaaa, bbbb, cccc, *nnnn WHERE 1111, 2222, 3333, *nnnn) into VBA.
This one is blowing my mind and I could use a little expertise. I'm retrieving data from an Excel sheet, using a simple SQL query using a textbox as input to my variable. It works great when I enter an integer to search for (such as 213 for example) but when I put in a mixture of numbers and letters (48A for example) I get the following error: Syntax error (missing operator) in query expression '[P&L]=48A'. [code]...
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 need to emulate an Excel Web Query in .net Below is the sample code.I get an Error500 when I attempt to do this in .net, however in Excel it works fine.When I change the URI to a normal website it works fine, and returns the html from the page, which i what i am after. I wonder if the problem lies from the fact that I am trying to return a datatable

I am using VB.NET to query via SQL an Excel spreadsheet using ADO. The general way is like this: SELECT [firstname], [secondname] FROM [Sheet1$] Which works perfectly However, one of the headings is called 3, so I want to do: SELECT [firstname], [secondname], [3] FROM [Sheet1$] However, this does not work. I know I can use * to get all columns, but later on I want to use (using dataReader): dr("3") which won't work

Can anyone tell me the fix for this? I know it has something somewhere to do with integers.

Im wanting to pull some data from our Remedy Server every so often. Right now we're having to do it manually; Data > Import External Data or New Database Query. The connection is called AR System ODBC Connection Source. We have to log into the server and then it pulls the info into the sheet. Im needing even if have to setup a conection myself first to just have this conection run every couple or two and update the excel sheet. We're using excel 03, Remedy 7.
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.

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

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 have this working on VB6 that saves a query in a excel sheet:

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 would like to generate an Excel file using a database query in VB.Net. How can I do it? To be more precise: I would like to "bind" a query (much like binding a query to a GridView) to an Excel file such that the rows in the table occupy corresponding cells in a new Excel file, and save the file to my computer. And then, mail that file to someone. While I can handle the mailing part, it's the creation of such a file that I need help with. Anyone know how to achieve what I want to achieve? PS: I need to do this in VB.Net and I'm using SQL Server 2008.
I know I've banged heads with this error before, but before the reason was because of my IMEX setting. This is the reason why I made two connections to the spreadsheet, one that uses IMEX=1 for the SELECT query and one with that option removed for the UPDATE / INSERT queries. So now I'm stumped why this is breaking in the following [code].....
Is there an issue with trying to open the same spreadsheet with two connections (I thought I had done this before)? Or some other issue that is causing this error to be thrown? BTW, I'm using this in a vb.net program so I don't think the issue is related to the security issues that asp users usually face with this error... On the other hand, I'm also on Win 7 and I know that its security is much tighter than on XP where I've used other programs that also update an Excel spreadsheet. I wouldn't think so, but would I have to run this in administrator mode in order to update the spreadsheet?

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 am working with VB in asp.net, The basic problem is, I want to pair up the elements in a string, exactly like request.QueryString() will do to the elements in the query string of the web page.
In my project I need to log all queries executed against my database. As an example we can use the staff user data here. In that class I have a function generating the command with the parameters as follows:
