You can upgrade VB to VB.NET as VB.NET is based on VB - but there are lots of points that you end up having to code yourself. Trust me on this - you can't automatically upgrade C++ to C#, and I don't go giving my email address to complete strangers.

Hi,
I have created an application that is basically a file browser with some special functionality to work with my employers content management system. I have managed to customize the code to work with Windows 7, coming from XP. The main issue was related to UAC and the writing to various sections of the registry.
However one problem does remain: I have some code for opening the files in their predefined editors, these are of course also defined in the windows registry. This portion works fine on Win7. I have implemented a function where the user can choose to open a file with a custom editor, this is done using a contextmenu which invokes the following code:
internal void EditAs()
{
try
{
ProcessStartInfo Info = new ProcessStartInfo(localFile);
if (File.Exists(localFile))
{
int i = 0;
foreach (String verb in Info.Verbs)
{
Console.WriteLine(" {0}. {1}", i.ToString(), verb);
i++;
}
}
Info.ErrorDialog = true;
Info.UseShellExecute = true;
Info.Verb = "OpenAs";
Process.Start(Info);
}
catch (System.ComponentModel.Win32Exception except)
{
MessageBox.Show("Could not open application. Please check executable path.",
"Application missing",
MessageBoxButtons.OK,
MessageBoxIcon.Warning);
}
catch (InvalidOperationException ex)
{
return;
}
}
The code works fine in win XP but in win7 I get an error message stating that
"This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel."
When I click OK on the first message I get the error message from my catch clause.
I have googled like crazy for a solution to my problem, does anyone have a clue?
Thanks in advance!

Why you are not doing the restore process via a SQL stored procedure...?

The following stored procedure will restore the database. This is helpful when you need to restore the database from other applications:
CREATE PROCEDURE [dbo].[sp_db_restore]
@DBName varchar(60),
@BackName varchar(120),
@DataName varchar(60),
@DataFileName varchar(120),
@LogName varchar(60),
@LogFileName varchar(120)
AS
RESTORE DATABASE @DBName FROM
DISK = @BackName WITH MOVE @DataName TO
@DataFileName ,
MOVE @LogName TO @LogFileName,
REPLACE
GO
Parameters
DBName - Database Name to be restored
BackName - Path & Name of the BackupFile
DataName - MDF File name
DataFileName - MDF File Path
LogName - LDF File Name
LogFileName - LDF File Path
Replace: Will replace the Database if it exists.

Check to see if the user is in your database. Read up on ADO.NET, there are thousands of examples.

Hi,
This the code i wrote to extract all the users details of an organization across domain
System.DirectoryServices.DirectorySearcher mySearcher = new System.DirectoryServices.DirectorySearcher("gc://dc=xxxdomain,dc=net");
mySearcher.Filter = ("(objectCategory=person)");
mySearcher.PageSize = int.MaxValue;
Console.WriteLine("Listing of users in the Active Directory");
Console.WriteLine("========================================");
using (var searchResultCollection = mySearcher.FindAll())
{
foreach (System.DirectoryServices.SearchResult searchResult in searchResultCollection)
{
foreach (string prop in searchResult.Properties["distinguishedname"])
{
Console.WriteLine("distinguishedname : " + prop.Trim());
break;
}
}
}
I got some output that only fetches the data for a domain where the user resides and not the complete data. Can anyone help me on this what went wrong in the code?

private void button5_Click(object sender, EventArgs e)<br />
{<br />
Form2 frm2 = new Form2();<br />
frm2.Show();<br />
}
when i run the code ,click button5,not any happened to me,Form1 still Form1,Form2 still not show?it just as have never happened?
what's the reason?thanks every to help me !
|
|
|
|
|
did you assign event handle?
buttion5.Click += new Systen.EventHandle(button5_Click);
If designer did create button5_Click function, then it should assign Click event
|
|
|
|
|
not that,i use button1 and other buttons,it also do not work
|
|
|
|
|
Form2 is being destructed immediately after the Show() method, causing it to be closed.

I've got a large Azure/C# project ahead. I was ready to
install Win7, but I'm not sure whether there are marked
advantages or disadvantages to using 32-bit vs 64-bit.
The project is mostly C#, which could be 32-bit or 64-bit,
but it will include at least one legacy unmanaged 32-bit DLL.
We haven't decided how to deal with the DLL yet...maybe a
wrapper, or maybe just set it up as a separate process that
will talk to managed code via TCP/IP (seems like comm options
are limited).
We'll also need to deal with a couple other unmanaged apps
that won't be going into Azure-land. But development concerns
would still relate.
If you can think of any notable advantages or disadvantages
in 32-bit vs 64-bit, I'd appreciate your insight.

Like others users some prefer using 32bit instead 64 bit, such as myself. My reason is this: Windows 64bit has a poor support and often doesn't work properly with 32 bit app

Hello, I'm new to the forum here. I'm currently using the Windows mobile 6 to create a database from the SQL Compact database edition. I'm currently facing this problem clearing of database. This is the code snippet below. I'm grateful for any help given. Thanks.
conn.Open();
SqlCeCommand cmd = conn.CreateCommand();
//cmd.CommandText = " DROP TABLE LOCATION";
cmd.CommandText = "DELETE from LOCATION where No = @No";
//=@No, DateAndTime=@DateAndTime,LocationInformation=@LocationInformation ";
-- cmd.ExecuteNonQuery(); -- This is the line where the error surfaced. "SqlCeException was mishandled (A parameter is missing. [ Parameter ordinal = 1 ] )"
this.Refresh();
conn.Close();

In your delete query you have specified a parameter "@No" but you have not added that parameter to your SqlCeCommand object.
cmd.Parameters.AddWithValue("@No", Value);
Just replace Value with a variable that has the value of No that you want to delete.
|
|
|
|
|
Actually, "No" is the fieldname of the database, can i still use this approach to clear the database?
//---create the two tables---
SqlCeCommand cmd = new SqlCeCommand(
"CREATE TABLE LOCATION(No int " +
"identity(1,1) PRIMARY KEY, " +
"DateAndTime nvarchar(80)," +
"LocationInformation nvarchar(80))", conn);
cmd.ExecuteNonQuery();
