View 10 RepliesI have an excel file with few macros written in VB language..
Now I want to create an installation file that will install this Excel file onto clients machine at a predefined (or user chosen) location just how a normal installation file works.. I also want the user to put a serial code that will be validated (don't know how)..
I think making an installation file in VB.NET is possible. My question is can I make installation file with just an excel in it and the feature of validating serial code using VB.NET?.. If it is possible that would be great.. otherwise what other solutions do I have..

I've found ways to read from a .txt file into Excel, but (having created and loaded an Excel sheet via vb.net 2008) I want to do the opposite which is to read each cell and row into a .txt file csv format like this: "Surname","Andrew","2","Mr","Hon.Member","PERCUSSION" I guess I need some way of knowing when the last row of data ends. Once in a .txt file I can load data in a variety of ways into several ListBox/s and labels without loading and reading the original Excel file.
View 3 RepliesI 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.
View 3 RepliesMy application is supposed to parse a text file (relatively easy) and create an excel spreadsheet report. Should I write a stand alone VB.NET application that saves the excel file, or should I use VSTO? I am unsure if there are any differences in terms of ease of development, usability issues, API functions available, etc.Are there any other programming languages/interfaces/libraries that will allow me to rapidly develop an involved excel spreadsheet? I am talking about things like functions, graphs, etc.

I'm creating a reporting web page as part of a standard VB.NET web application. The page is data driven, with jquery making calls to a web service local to the application to get values of elements that are dynamically created in the DOM. Ultimately these dynamic elements and their values are all wrapped up in a JSON object, so that part of the client side is fine.
Right now, I can pass that JSON object to a method in the web service which creates an SQL Data adapter from the values and queries a database. My ultimate goal is to have this client JSON data be used to query the database and construct an excel file to send back to the user, or failing that a CSV file.
It's my understanding (from working with PDF file generation) that this type of function can only be done on the server side of the web application, not even from the web service (i.e. I can't have the web service return an array of bytes and have JavaScript/jQuery present that as a file).
So, how do I go about this? Now I have my JSON object on the client side, where should I be sending it, how, and how do I go about returning my file?
I've read about either storing the JSON in a hidden field and having the server take the elements value and go from there, or using AJAX to send the JSON to the server just before a postback is made to fire off the server-side function to run the query and return the data.
I just need a little guidance, and a little help understanding where to use the hidden field, or what I am actually doing with the pre-postback AJAX call.
i need to create an application(VB.net or VBA) which will convert text file contents into excel. u the contents fromt he text file have delimiters(special characters).The condition is while converting it should remove all the delimiters and paste teh content between two delimiters in to one cell.For Eg:

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.

2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module
3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.

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.

View 1 RepliesI have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
I took oledbconnection with excel file, after disposing this connection i m still unable to open that excel manually,It shows some access error.
