Unable To Import Dll Files
Mar 24, 2010
I'm using VB.NET 2005 RC and I have built a custom component which consists of a search screen, data grid, dataset etc. The whole project is designed to be imported in to any new application as a custom control which can then be programmatically changed via its methods, events etc. When I tried to import the .dll in to a new windows forms project all the extra stuff contained in my project was also magically imported (such as the dataset I had used, the SQL connection) etc.I have set these their modifier to be private but still they are imported.
What can I do so when a developer imports this custom control in to their toolbox for use, only the control is shown? Otherwise it looks a bit weird to have access to the dataset I'm using with access to the dataset I'm using within the control.

I got a graphic that I got to rotate about a specific point. So, I got to define the centerX and centerY, the point about which to rotate. For that, I am importing the namespace: "system.windows.media.rotatetransform"The following problem then arises when the above namespace gets underlined with a green curly line and when I place the mouse over it, the following message is displayed:"Namespace or type specified in the Imports'System.Windows.media.rotatetransform' doesn't contain any public member or cannot be found. Make sure the namespae or type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

I'm looking for a solution to import or link logs (csv and txt files) to Access using ODBC. These files are in a directory and I would like to link each of them to a table in Access to analyze their content. I'd like to use ODBC rather than the Access' Import Wizard because I want to keep the possibility to change the format and/or delimiters of my files if necessary.I settled an ODBC Driver "Microsoft Access Text Driver" but when I try to open the connection in Access, I get the error "You cannot use ODBC to import from, export to or link an external Microsoft Office Access or ISAM database table to your database".This connexion works perfectly in Excel and enable me to get the data in an excel spreadsheet. I'd like to do the same from Access to use Access' functionalities!

how I could go about making a simple little program in Visual Basic 2010 that has a button you click with drop down menu beside it to search for an excel or sql file on your computer and then you select it. Then you click a button saying "import into sql" or a different button saying "export to excel."
These buttons would of course do what they say... either importing the chosen excel file into sql or exporting the sql file into excel.

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 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 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.

I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}

I've got a piece of VB script that runs from a logon script. It contains the line: objShell.run("regedit /s/c \SERVERNETLOGONScriptTest.reg", 0) Which imports a file into the registry just as I want. The /s switch means that I don't get the two warnings from the regedit program which is exactly what I'm looking for but everytime it runs the UAC asks for permission to make changes to the computer which of course I don't want to happen.

I designed a vb.net application. In this application I am using some file which are in WindowsSystem32 folder. Each and everything is working file, but when I install my application on any x64 machine. My application is unable to read the in WindowsSystem32 files. I think this is because of WOW64(windows-32-on-windows-64) issue. I don't want to install these files at any other place because of application security purpose.

I have a VB.NET application that will let me preview .DBF files that come in from some of our clients. The application then attempts to spit out a CSV from this file that we can then use in our various environments. This application worked under Windows XP 32 bit. Our company recently upgraded most of us to Windows 7 x64 which has caused this application to fail. I verified that the target build for this application is x86 and not "any CPU" and rebuilt the app but same issues occur.
It originally used System.Data.Odbc and connection.ConnectionString = "Driver={Microsoft dBASE VFP Driver (*.dbf)};SourceType = DBF;SourceDB=" & dbfSourcePath & ";Exclusive=No; Collate=Machine;BACKGROUNDFETCH=NO;".
The location of the failure is at connection.Open(). The error given is: "ERROR [IM001] [Microsoft][ODBC Driver Manager] Driver does not support this function".
I noticed that the drivers for VFP were not installed and that the Access DBF drivers did not work similar to the post here. The fix listed there is to install VFPro SP2, however, we do not have any FoxPro installs to install a service pack on top of. I then tried to install the OLEDB driver for VFP 9.0 and am now using System.Data.OleDb and connection.ConnectionString = "Provider=VFPOLEDB.1; ourceDB=" & dbfSourcePath & ";" but it now tells me that the connection.Open() line has this error: "Feature is not available".
I am at a complete loss as to how to get this application to work under Windows 7 x64. Below are the 2 variants of the code with the file open path removed for readability (I have verified the path and file exist):
ODBC version:
Imports System.Data.Odbc
Dim strSelect As String
strSelect = "SELECT * FROM " & dbfSourceName
[Code].....
How can I use either an OLEDB or ODBC connection to open these .DBF files under Windows 7 x64?
