Local (Generic) Data Directory Reference For Excel Files?
Dec 8, 2011
I can reference the local (generic) data directory for an SQL file as follows:
Dim
T01Database As SqlCeConnection =
New SqlCeConnection("Data
Source=|DataDirectory|Test File.sdf")
I get a "file not found" error when trying the same syntax for referencing an Excel file:
Dim
T01Workbook As Microsoft.Office.Interop.Excel.Workbook
= T01Application.Workbooks.Open("|Data Directory|Test File.xlsx"
)
correct syntax for referencing an Excel file in this manner?

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.

I have a straight-forward task I'm attempting to accomplish. I have the mechanics down, and need to hammer out the details but I'm stumbling across one small point. :)
This script is supposed to take the files in the local C:Temp directory, and copy them to a selected user's shared directory on the file server.
Protected Sub btnCopy_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnCopy.Click
My.Computer.FileSystem.CopyDirectory("C:Temp", "\MAVERICKVOL1Users" & ddlName.SelectedValue & "DESKTOPRECORDINGS", True)
End Sub
This script does indeed work (and I'm aware I need to create exception handling) but it only copies what contents are on the server's directory of C:Temp rather than the local source directory.
I'm using VB.NET/ASP.NET to achieve this.
How am I able to direct my function to use the local user's directory rather than the remote server?

I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?
[Code]...
So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.

how to do it in either the one-click or in a setup project.
I would also like to have a condition that if the files exist that they are not overwritten with an updated installation.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

I have a mutable class that I'm using as a key to a generic dictionary. Two keys should be equal only if their references are equal. From what I've read, in this case, I don't need to override Equals, GetHashCode , or implement IEqualityComparer.

Does anybody know how to pass a reference to the current item in a generic list, when processing that list? In VB.NET you have to use a delegate wrapper to pass parameters in a delegate, which I have set up OK, but I don't know how to get a reference to the current item that would be the parameter used at in the example below. Using the Current property of the list enumerator doesn't seem to work, but how else could this be done?

My application is often used to import volumes of data. The application currently supports .CSV, .XML, and XLS. The question relates to handling EXCEL files. Specifically, what are the best practices for coding?
Today, since customers are beginning to see .XLSX files coming in, I modified the code to use either JET.OLEDB.4.0 or .ACE.OLEDB.12.0 depending on whether it was reading an .XLS or an .XLSX. My instincts tell me that cannot be the correct way to go about this. First, customers still using Office 2003 are going to have to download the AccessDatabaseEngine in order to read the .XLSX files. Second, what if a customer installs Office 2010? Are they going to have the 12.0 stuff or am I now faced with another issue.

I have a VB.NET project which references a dll of another program. dll file location is something like "C:Program FilesAppNameAppName.dll" and on my project's references tab the dll's path shows this. When the copy local property is true, everythings works fine. When it is false, I get a runtime error saying dll cannot be found. The other program is a restricted access application and I can not distribute the dll with my project. How can I force my project to look for dll under "C:ProgramFilesAppName"? I didn't have this issue with VB6.0.

Is there a way to default the Copy Local property of references that I add to my projects? I figure there has to be some sort of method since adding a reference to a VB componentdefaults to False. (for example, start a project as a class library and then adda reference to System.Windows.Forms, it will default Copy Local False.) Is that somethingin the DLL's settings or configuration that I could replicate in my DLLs to force that

I have an application that that uses process.start. It works fine on my development machine...but not on an installed machine....at least not for a local file. The following illustrates my problem...the reference to the url works fine and every time. However, the reference to the local file may work the First time but on any following attempts will close the application with a WindowsApplication1 error. Since it can find the file occasionally it is not a file problem.

I am using data grid view in Vb.net and would like to load two excel files into it. My two excel files look like this:
[Code]...
The problem I want to solve is the following:I would like to map the values from the data set in file 2 to the sorted data set from file 1. So for example If I want to sort all the data by id# descending then (using the example from above) the data in datagrid view1 and in datagridview2 should be reversed.
Right now if I sort the column from file1 in datagrid view all the other columns in THIS datagridview1 are also sorted in relation to column2. What I want is that the columns in file2 will also sort according to file1.

I am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.

Scenario: I want to develop an application.The application should be able to connect to my remote server and download data to the local disk , while downloading it should check for new files and only download the new ones simultaneously creating the required(new) folders.
Problem: I have no idea how to compare the files in the server with the ones in the local disk.How to download only the new files from the server to the local disk?
What am thinking?: I want to sync the files in the local machine with the ones in the server. I am planning to use rsync for syncing but i have no idea how to use it with ASP.NET.

I'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:
1) set a reference to the Microsoft Excel 12.0 Object Library
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'.

How does the GC dispose objects created in the following 2 scenarios?
1)
Private Function DoSomething() As Boolean
Return New DatabaseManager().Insert()
End Function
2)
Private Function DoSomething() As Boolean
Dim mngr As New DatabaseManager()
Return mngr.Insert()
End Function
In Option 1, I don't create local variable to hold the reference of the object. In Option 2, I hold the reference in local variable.What option is better and why? (if any)
