Hi, I'm set the SelectedObject property of a PropertyGrid with a class that have two properties of type Point, one is Point1 and another is Point2. When running the program I can set the X or Y value of point property. How can I distinguish between the Point1.Y and the Point2.Y property? In the PropertyValueChanged event there is the e.ChangedItem.Label value that contains only Y and not Point1.Y or Point2.Y. I have saw that there is the "((System.Windows.Forms.PropertyGridInternal.PropertyDescriptorGridEntry)(((System.Windows.Forms.PropertyGridInternal.ImmutablePropertyDescriptorGridEntry)(((System.Windows.Forms.GridItem)(((System.Windows.Forms.PropertyGrid)(mProp)).SelectedGridItem)))))).HelpKeyword" that contains Point2.Y but is an internal property and I can't read it. How can I solve the problem? Thanks a lot!

How can i load an icon from an embedded resource in mt application into a System.Drawing.Icon
|
|
|
|
|
Get a stream to the resource using Resource.GetStream() and then use Image.FromStream()..You should be able to cast that to an icon or something to that effect...

I am trying to use a C# DLL assembly from in-memory. This DLL uses a Win32 Native function which requires HINSTANCE of the module in DLL. So, I try to use the Marshal.GetHINSTANCE Method. It works fine if I use the DLL from physical drive. However, the moment I try to run the DLL from in-memory, I get an error. After some research in MSDN, I found the following remark in the help on Marshal.GetHINSTANCE Method:
"When dynamic or in-memory, modules do not have an HINSTANCE."
Now, my problem is that when DLL is run from in-memory, its modules do not have HINSTANCE as per MSDN documentation. However, the Win32 Native function requires HINSTNCE as one of the parameters. I tried to use null or (IntPtr) 0, etc., but they do not work.
Is there any solution to this problem?
Thanks in advance.

When the .DLL is in memory the HINSTANCE is your application, not the DLL.
What's the Win32 Native function your trying to call and what are you doing with it?

I am new of ASP.Net and facing a problem that whenever I do connection ASP.Net with Sql Server it gives me error
"Login failed for user 'ComputerName\ASPNET'.
Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'ComputerName\ASPNET'.
Line 78: thisAdapter.Fill(thisDataSet,"Customers");
I am doing like this "
string myConnectionString = "Initial Catalog=Northwind;Data Source=localhost;Integrated Security=SSPI;server=ComputerName\\MY2000";
thisConnection = new SqlConnection(myConnectionString);
and so on. It is working fine in windows form.
Thanks

When you're using ASP.NET, you're working as the ASPNET user. That user needs to have the right to log in to SQL Server. The easiest way around is to log in with username/password instead of using Windows authentication.

Thanks for your mail.
I am doing like this
string myConnectionString = "Initial Catalog=MyDB;Data Source=localhost;Integrated Security=SSPI;server=ComputerName\\MY2000;user id=sa; Password=";
My password is blank.
I am not using windows authentication.
It is working without using ASP.NET.

|

If I remove this "Integrated Security=SSPI;" from connecting string then It is working fine.
Thanks a lot for your kind help.

Hi All,
I'm a newbie. I am trying to find out how
to store string data read from a file into
a table or another string.
I keep getting the error, cannot implicitly
assign a string to string?!
Help!

Perhaps if you posted your code, we could see what's going on ?
There's no reason why you can't build a string from the value of another string. What do you mean by table ? How do you want the string to move into it ?

Hi Christain,
I solved the problem. It was my error
using improper syntax.
Thanks for your reply.

Sounds as if you have a simple problem, but cannot be sure as you haven't posyed your code.
Try using the ToString() method, contained within most classes in the .NET Framework
|
|
|
|
|
Yes, it was a simple problem solved by using
the proper syntax. I guess you would call it
a newbie error. I keep building on acquired
knowledge. I'm getting there.
Thanks for your prompt reply.

I have a foreach loop which checks on a ArrayList
I would like to include the Timer object to go through the foreach loop at a 1 second interval.
How can I do this?
Thanks,
BingLin

1-Add Timer
2-Set Enable Property To true
3-Set Interval Property to 1000
4-Subscribe to Tick event
5-Add the for loop in Tick event handler

i've created the object:
System.Timers.Timer myTimer = new System.Timers.Timer(1000);
I have this:
public void start_click(object sender, System.EventArgs e)
{
//initialise connection to my hardware thru com1
ArrayList frames = this.gCont.GetResponseFrames();
foreach(byte[] frame in frames)
{
//do my stuffs
}
}
how should i use the timer to check through the foreach loop after the creation of connection and arraylist?

I told you in the previous post
You need to write this code in Timer Tick event handler
Not in Command Click event after you set the properties
private void timer1_Tick(object sender, System.EventArgs e)
{
ArrayList frames = this.gCont.GetResponseFrames();
foreach(byte[] frame in frames)
{
}
}
}

I am assuming you are writing a Windows App.
Basically you click on the timer in the Toolbox panel (in design view) and drag it to the form. Go to timer properties an set Enabled to True and Interval to 1000ms (1s). Double click on the timer icon in design view, This will then switch to your code and it will have added the following:
private void timer1_Tick(object sender, System.EventArgs e)
{
// forech loop and associated code to go here
}
Put your code inside the method and it will run ever second

I'd like to write a program that has no UI at the current time, but I might like to add one in later. What would be the best type of project to use for this? Should I start a console app, a windows forms app (and just remove the form), should I start a class library app or just an empty one and add as I see fit?
Thanks for the help
