i'm creating a system now using vb.net 2005, .net framework 3.5. I'm using MySQL 5.1 as my backend and I've created a role so that I'll grant the specific user if he fits with the current role. My question is how can i modify the username and password of my database connection located at machine.config file under connectionStrings? The system will be used by different users and every user has its own account in the database.
Example:
I have a user named perry. The connection string would be like this:
<add name="LocalMySqlServer" connectionString="server=localhost;user id=perry;password=pass1234;database=mysql"/>
Another user named harris:
<add name="LocalMySqlServer" connectionString="server=localhost;user id=harris;password=harRis101;database=mysql"/>
You will find attached the source code of a small program. I wanted to know if it was possible to modify the connection string in Web.config and use a connection to MySQL. I made some attempt, but does not connect.
Dear Friends: I have some files in 1 folder directory that show "XML Configuration File" under type. But none of these files show the extension .config. The directory filesare like C0150,C0150_new,C0200,C0200_new etc. I need to change only 1 attribute of each of these files. I need to write a VS.Net project to do this. I have to send the .exe file(from bin directory of this VS.Net project) to my client and they will just double click the .exe file and it will change that attribute in all the .config files.
The C0150 file looks like this: <?xml version="1.0" encoding="utf-8"?> <configuration>

I have one datagrid, as shown in the screenshot. However, I'd like to change the header to be more descriptive. The ones listed there are taken from the database column names, and so they're not good for eyes.

I have an application Bbb.exe. I found that there are two configurations.Bbb.exe.config and Bbb.vshost.exe.config. They are exactly same.For some reason, I changed Bbb.exe.config and keep Bbb.vshost.exe.config unchanged.
I have used the following code to update the app.config file. The code works fine and didnt shown any exceptions, but values are not storing to app.config ?
I downloaded and installed Refactor. The install worked fine and Refactor works in VS 2005. However, I also have VS 2008 installed and I cannot get Refactor to appear in that IDE. Is there something I need to do to get Refactor to appear in VS 2005 and VS 2008 on the same machine?

know open an xml file into a datagrid. The xml file is stored in a secured ftp with username and password. Just as an example if the site ftp.mysitesite.com, with username "xxx" and the password "XXX" has the file 123.xml, then how do I load 123 into a datagrid. Is it possible to store these info to a variable in app.Config and use that variable to access the site?
I want to ask that where to store connection string in VB.Net.AS in ASP.net we can store connection string in web.config file and access it in the foll. way [code]In VB.net where to store conn. string on form_Load or any other place???
I have a question about the App.Config file. My understanding is that the connection string is stored within this file. I have setup my application so that the App.Config file is not only written to c:users<username>appdatalocal but also to c:users<username>appdataoaming. I plan to encrypt the connection string, my question at this point is will it encrypt the connection string in ALL copies of the App.Config file? It looks like at this point that the App.Config file is stored in two places on the hard drive.
I am trying to make a client server form application using VB2005. I am using VS2005 Professional for development.
The problem is as follows: When more than one client tries to connect to the server. The connection is refused and the Client gets an exception in Connect() method - Target machine actively refused the connection.
This problem occurs only when 2 or more clients try to simultaneously connect to the server. For a single client accessing at a time the problem does not occur. The code segment is as given below:
-----------1 Module Imports System.Net.Sockets Imports System.Net Public Class FrmMdiParent Dim WithEvents wsServer As New Winsock2005DLL.Winsock Private Sub FrmMdiParent_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing [Code] .....
The above exception is thrown when more than 1 clients try to access the server simultaneously.
I have a class library (Named ADI), that needs some configuration settings from the project using it (like connectionstring, filesystem locations etc).

Imports System.Data Imports System.data.OleDb Public Class Form1 Dim con As OleDb[code].....
By this i can fetch only one row(the last row) of the access....how to modify the above code to fetch all the rows starting from the begining from the database..........

I've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads
Our main application has both a asp.net and winforms component. There is a class that is used by both sides and needs info from either the web.config or app.config files. The class itself does not know if it's on the client side or on the web server (at this point). We are getting errors when it's attempting read app.config when it's on the web side. Is there a way for the class to tell if it needs to read web.config or app.config?
