Call/run Excel Macro Within A Separate Visual Studio Application?
Dec 14, 2010I'm looking to call an excel macro (excel version 07) within a separate visual studio application (visual studio express 2010). Basically, a user clicks a browse dialog button to select a xls or xlsm file which is then added to a listbox. Next, I would like the macro to run when another button is clicked. The macro looks at the first column in excel and moves the listed .tif images from one folder to another. I referenced the excel libraries, but seem to be getting hung up on a few code statements (''''ERROR see code below). I would like to run the macro within visual studio for any selected excel file or add the macro somehow to the selected excel file and run it.
'Here is the button click procedure
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
filenames = lstFiles.SelectedItem

Office Automation :: Closing/Quitting Excel From Visual Studio Application
Jul 13, 2010I am using visual studio to create an application that opens an excel file and then for each entry in the first column the entry in the second column is stored in an array. Then excel opens two other workbooks and for each entry in the first column it searches for a match in these other two workbooks and stores the corresponding value in an array.
Anyway, the problem is closing excel afterwards. I have used the thread: [URL] to work through the basics of cleaning up. I used the cleanup code provided and added the WithEvents caveat. I do not have strict option on.
I believe the problem is the fact that I have three workbooks open.
This is my cleanup code: (wrkbk, wrkbk2, wrkbk3 are the workbooks; datasheet, datasheet2, datasheet 3 are the worksheets; excel is the application)
Code:
GC.Collect()
GC.WaitForPendingFinalizers()
GC.Collect()
[Code]....
I got the impression that order was important in the cleanup procedure so I have tried some variations of moving the workbooks and worksheets around.

Excel As A Database Backend To Load Into A Datagridview
Mar 8, 2011I'm using Excel as a database backend to load into a datagridview.
This is how I connect and bind to the dgv:
vb.net Dim sFileName = filelocation & "checks.xls"
Dim connectionStringTemplate As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=Yes;IMEX=1"""
[CODE]...
It connects and populates fine. I have a button for the user to "refresh" the datagridview. I cannot get it to correctly refill the dgv. I have tried setting the bindsource.datasource to Nothing along with the datagridview datasource, but I get an error that brings up the Visual Studio debugger with no real error message...

Developing MS Visual Studio Like Application Using MS Visual Studio 2005
Nov 27, 2009I have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

Make A Web Application In .NET Using Visual Studio 2008?
Jun 22, 2011I am trying to make a web application in VB.NET using Visual Studio 2008 that will accept login credentials and compare them with an Access database for authentication/validation. I found lots and lots of examples for how to do this with a Windows Form App, but none with a ASP.NET Web App. tried to modify the steps for a web app but I'm not sure how to make it work. The database connection is good and the query seems to work fine. Here's where I'm having trouble. In the tutorial, he says to use:
01 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
02 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
03 Dim r = Me.UsersTableAdapter1.ValidateUserNamePassword(Me.Txt_UserName.Text,Me.Txt_Password.Text)
[code]....
No matter what I put in for the username and password (as long as they are valid values) I always get a "success," never a failure. I know my query is working right because I put a gridview on the page and bound it to the result from the query; when I type in a user/pass that is not in the database the gridview is blank, when I type in a correct user/pass the gridview displays that row from the database.

Workflow & Change Notification In .NET 2010 Application With Backend SQL Database
Jan 28, 2011I am developing an app that uses a sql backend database (hosted on a different machine).The app I am developing will be run on 10 different workstations simultaneously.Sometimes the app will change the database in such a way that the database needs to initiate a workflow process and I'm not sure of the best way to do this.Also, when database changes happen, how does one best notify the other app instances that the change has happened, so they know to refresh their data? I was thinking that triggers could help initiate the workflow but it might be nice to develop the actual workflow in .net code.Should I write another App to run as a service on the server and do the work and also to tell the client apps when things change?
