Hi,
Thanks you for your reply, but when i add the sql server as a prerequisites to my setup there is no way to set the instance name for the sql server that must installed.
do you know how to do that.
and do you know how to add custom dialog with different controls such as 2 radiobuttons and 2 textboxes.
Thanks alot for your help.

You should NOT be doing that.
SQL Server should be installed seperately by the user, if at all. Your application installer should ask the user for the SQL Server connection details, like servername, IP address, port, instance name, username and password to use to install/attach your database.
If the user already has SQL Server installed, they can use that, as well as putting the database on a seperate machine from the one your app is installed on.
By putting the SQL Server installation inside your own setup, you are limiting the choices the user has to install your app.

Not a good idea.
Run the SQL server installer using its own setup.
You can however, use custom actions to make your installer do certain tasks like register a dll etc.

I have a program for synchronizing my computers time from the time on the Internet, but since I updated my program to Windows7 it no longer works. If I run the program by right clicking on it and running it as an Administrator it will run and change the time on my computer. Otherwise, the program runs and it does not change the time.
How do I run this program in C# as an administrator, any help will be greatly appreciated.
Thanks in advance

This is by design to make it harder for program to make suspicious changes to the system. You can modify the manifest to indicate that the application should always be run as an admnistrator (or modify the link). That way, you will have one less step to do as a regular start will start the application with administrative right. You still have to confirm that you want your application to have that priviledge.
Depending on the application, it might make more sense to check the time and only if a change is required then prompt the user. This will typically be done by using 2 exécutable files. That approch would be the one an application with auto-update would typically use.

It would be my guess (and suggestion if it works) that you could and should create a Windows service that starts automatically, logged in as say System, and stays alive as long as Windows does. Then you would never interact with it nor been bothered by it or any UAC dialog.

You do not need a program of your own for setting your computer's time. There are time servers on the internet, and Windows can get the "correct" time from them.
|

You are correct that setting the time does require admin rights.
I suggested a couple of possible solutions here[^].

Care to elaborate more on what are you trying to do here? It would help you in getting some direction.

Why is common sense not common?

I really need to take a look at my code that does that (at least single-right-click). I don't claim it's the best way. But seeing as you cross posted, I won't hurry.

Hi,
i want to develop a program in C# which reads and analyzes values from Pulse LabShop (a Bruel & Kjaer tool to measure & analyze acoustics).
With a VB2010 example i found i was able to read out values via the COM&OLE interface:
-------------------------------------------
Public Class Form1
Dim myPulse As PulseLabShop.Application
Dim myDataSet As PulseLabShop.BKDataSet
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
myPulse = CreateObject("Pulse.LabShop.Application")
myPulse.Visible = True
Me.Text = "ControlPULSE " + myPulse.Name
Label1.Text = myPulse.Project.FunctionOrganiser.FunctionGroups(1).Name
End Sub
---------------------------------------
Now i wanted to code the same in C# 2010:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace C_PulseTest
{
public partial class Form1 : Form
{
PulseLabShop.Application myPulse;
PulseLabShop.BKDataSet myDataSet;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
myPulse = new PulseLabShop.Application("Pulse.LabShop.Application");
myPulse.Visible = true;
this.Text = "ControlPULSE " + myPulse.Name;
label1.Text = myPulse.Project.FunctionOrganiser.FunctionGroups(1).Name;
}
}
}
However the code is not working due to an error in the last line:
Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))
I also tried [0] or [1] or ("string") as index - but all with the same error...
Is there something wrong in general with my C# code?
Any other idea why the index is not working?
Thanks a lot for all possible help!

Where are you getting the exception? I can see 2 places that could cause a problem.
|
|
|
|
|
I get the error in the last line with reference to (1):
label1.Text = myPulse.Project.FunctionOrganiser.FunctionGroups(1).Name;
|
|
|
|
|
What happens if you inspect myPulse.Project.FunctionOrganiser in the watch window? Is there a method for getting the count of FunctionGroups elements? My suspicion is that this is null - BTW, C# is zero based so you would need to use 0 and not 1 (even though when you tried it, it didn't work for you).
|
|
|
|
|
Interestingly the following line returns "7" (There are indeed 7 Function Groups available)
label1.Text = Convert.ToString(myPulse.Project.FunctionOrganiser.FunctionGroups.Count);
When i compare the Object myPulse in VB2010 and C#2010 i saw that in VB2010 i can unfold it to Project to FunctionOrganiser to Function Groups and also a few properties like "Name" are shown. In C#2010 i can't unfold it and there are also no properties shown.
So could it been that i have to initialize or define the object myPulse in a different way?
Thanks!

As a trick, you could run your VB.NET code through a C# converter and see what it comes up with. When I ran it through, I got the following:
private void Button1_Click(System.Object sender, System.EventArgs e)
{
myPulse = Interaction.CreateObject("Pulse.LabShop.Application");
myPulse.Visible = true;
this.Text = "ControlPULSE " + myPulse.Name;
Label1.Text = myPulse.Project.FunctionOrganiser.FunctionGroups(1).Name;
}Now, that would require using the Microsoft.VisualBasic dlls in your app, but fortunately you can translate the offending line as in the following:
Type type = Type.GetTypeFromProjID(("Pulse.LabShop.Application");
object pulseType = Activator.CreateInstance(type);
if (pulseType != null)
myPulse = (Pulse.LabShop.Application)type;That's if you can't just directly call new on Pulse.LabShop.Application (that would be worth trying).
|
|
|
|
|
It is possible to create the object by
PulseLabShop.Application myPulse = new PulseLabShop.Application("PulseLabShop.Application");
...However, i get still the same error.
The type conversion didn't work because of an error to cast the object-type to myPulse.
Hmm seems like i've to think about writing a dll to access the programm in Visual Basic and to incluede in my C# project - What do you think?
|
|
|
|
|
...so with a dll written in VB2010 and included in my C#2010 code it works fine...now only the question is if this will influence the performance in a significant way or not...

Do you have JustDecompile[^]? If not, you really should consider installing it - with it, you could decompile your VB version, and then view the resulting source as C# to see what's happening.
