In my application I want the user to enter information that can be stored in BOTH an SQL database and and Excel spreadsheet. I tried research but can't find the code to include or import Excel
into my project.I've seen examples like:
Dim excelApp As New Excel.Application
Dim excelWB As New Excel.Workbook
etc....
but VB doesn't recognize it as a shared namespace. Is it possible to load a spreadsheet into a VB project with express edition?
i'm using visual basic 2008 express edition and having a problem in saving the data i've added in datagrid to excel. i use inputbox to add data into the datagrid. when i click the save button, the data from the datagrid must be save to excel. this is the code i get from some forum and i already edited it but it only saves the last data/row i inputted.
I added the reference and the "Imports" line, and I get the folowing error on the line
Code: Dim oApp As New Excel.Application Dim oWB As Excel.Workbook = oApp.Workbooks.Add() Dim oWS As Excel.Worksheet = CType(oWB.Worksheets(1), Excel.Worksheet) COMException was unhandled
Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))
I am trying to read off some cells from an Excel File. I can't figure it out. Here is my code:
Public Class TOC Dim ExcelObj As New Microsoft.Office.Interop.Excel.Application
[Code]....
After making WorkSheetObj I dont know what to do.. I am trying to dynamically change the Texts of Four buttons. The text values are to be to read off of Excel cells.
I'm using the 2008 express edition. Now, I created an application that will allow the user to choose transaction in the combobox.text and input its price and quantity using an textbox.text. When the user click button1, it will be push in the datagrid/datable I created. And when the user click the button2, it must be save to excel file. The only thing I need is how to save the data from datagrid/datatable to excel. This is my code.
The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.
I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

My company currently has vb.net 2003. I am tasked with evaluating vb.net 2008. And suggest if upgrading to 2008 edition is necessary or if it will be beneficial. For this purpose I decided to experiment with vb.net 2008 express. I have some questions regarding this.
1) Will vb.net 2008 express edition will give me idea about new features etc. ?
2) If I install vb.net 2008 express edition on machine which has vb.net 2003, will it cause any problems to vb.net 2003 ?
3) If I code in vb.net 2008 express edition, on upgrading will this same code work ?
I'm using Visual Basic 2008 Express and am having problems making an install.It has been suggested that the Express (free edition) only allows you to install only on computers that also have Visual Studio.Do I need the Full version to be able to distribute my application to a variety of computers?
I was wondering what people who have used VS Express editions think of them.My wife is thinking about taking a class in VB .NET so I thought maybe it's worthwhile to install VS Express at home for her to get a headstart.
I know the express edition of Vb does not give a detailed publish but i want to ask something. I have made program that uses database (Sql), and also my program uses folders (Help, Pictures etc..) I tried to publish my program but the express edition does not have an option to add my folders. So i tried to publish with "inno setup" program. But this time my program does not work in computers which dont have "Sql Server 2008 express". I tried to put "Read me " file, that says "First setup Sql Server 2008 Express from internet then setup .Net Framework from internet then setup the program" but it is so hard for user to do those thing. Is there any way easier? (Does the computer must have Sql Server to work with my database?)
I want to use the free express edition but am concerned about limitations. Wikepedia mentions "Limited options for debugging and breakpoints" as one limitation. None of of the other limitations mentioned concerned me.
I tried installing VB.NET 2008 express edition and I had to stop it because there was no network connection.Now it just gets frozen half way through the install everytime. Where are the registry values so I can delete them and install the program. So irritating.
I'm doing a project for school (I'm in Year 6, Primary School, Australia) and I'm trying to create a measurements converter with Visual Basic. Unfortunately I have a problem (and no teachers in the school have a clue on how to use visual basic).Basically the program just converts a specified amount of one unit of measurement and converts it to another unit of measurement.A message box then pops up telling the user the answer. Eg. A user specifies that they want 1 mile converted to 1 kilometre a message box will pop up telling them what the answer would be. In this case it would be about 1.6 kilometres.

I would like to have one combo box associated with another combo box. When the first one is selected the price is displayed in the next one. The information is got from a txt file and the item name loads in the first combo box and the price loads in the other combo box. What I want it to do is to show the correct price when the first box is selected for the item Here is a copy of my code at the moment. [code]

I found a forum post about Visual C++, Visual C++ 2008 Express Edition And 64-Bit Targets , but how do I develop x64 applications under Visual Basic 2010 Express Edition?
I have downloaded VS Express 2010 edition from Microsoft website. I want to convert a VB 6.0 project into VB.Net using VS Express 2010. Is it possible to do it without the "Upgrade Wizard"? How much will it cost me to get basic VS 2010 Professional with the "Upgrade Wizard" option? What other tools (that I might require during conversion) are missing in the VS Express edition?
I have almost finished working on a small application using VB.NET 2008 Express Edition as front end and SQL Server Express as back end. Now my next step is to generate reports for the application. Is there ANY way I could create reports in VB.NET Express Edition?

I have a form application created with Visual Basic Express Edition 2008 which has a Binding Navigator that navigates through records in a database (Access .mdb file Added with the "Data Sources" wizard). My problem is thus: I need to run code straight after the form controls have been updated with the particular records data. Is there any way of doing this? I'm stuck because all the backend database code is hidden.
