This doesn't work with every application. Some application may retain window position and other state information written to storage when closed and reapply that state information when opened. This is often the case.

Thanks for the tip, just tried it with a command window app and it minimizes the window fine. Is there any way to override the loaded state information? It doesn't matter that much because it's an in house application but it would be nice.
Cheers

Hi all,
I need to remember the selection ( eg. the radiobutton ) that the user selected even after the program closes so that the next time the program opens, the previously selected option whill be chosen. How can I do this?
There's a property in Visual Studio.NET call dynamic properties, is this the answer to solving this problem? Thanks in advance.

Why not just save the values in a text or binary file using
System.IO.StreamWriter / StreamReader or
System.IO.BinaryWriter / BinaryReader
Save the settings in form_Closing and read them in again in form_Load.

Are you saying that you dont want to define t3 but you still want to display the information that you would have put in t3 in your datagrid?
Any particular reason why you don't want to define a table variable?

hi
my supervisor want me to do that , just for security matters
can u help me ?
he told me that i can declare a DataSet in the addRC() function , and retrive this DataSet from the button1_Click() ..
any thing to help me with ??
|
|
|
|
|
What addRC() function??
If you use a dataset then to the best of my knowledge you still need to use a datatable but you don't have to declare tehm first because the DataSet calss has a tables collection.
DataSet.Tables.Add()
You can add a new table to your dataset using the above code
once you have added the table to the dataset you can refer to it by
DataSet.Tables[0];
Then you can set up your table programaticaly and your away.
Hope this solves your problem

I have developed an installer for an application that utilizes the cygwin gcc compiler. I have to bundle the gcc together with the application. I have copied the structure of the cygwin gcc directories as it is. There a few shortcuts in the gcc directory structure that point to some directories and files residing inside the gcc directory structure. I also corrected the shorcut targets using orca after making the release msi. The problem is that the compiler doesn't seem to find the files and directories reffered by the shortcuts. If i replace the gcc folder created by the installer with the original gcc directory all works well.
I have made sure that the directory structure is copied as is and double checked it as well.
Kindly help me out of this problem.

I am trying to figure out the best way to convert a HTML page to an image. I need to be able to do this without actually displaying the URL in the browser and need to capture the entire horizontal and vertical size.
I have see some commercial products that appear to be using the IE control to perform this functionality but I cannot find anything on the web that discusses how this is done.
Does anyone have any ideas about how this can be accomplished?

Unfortunately, it is not that simple. I need to be able to capture the entire rendered page regardless of the size - not just what is displayed in a browser window. Additionally, I want to do this entirely in code with no UI. I believe most of the ActiveX controls and other utilities out there are using a hidden IE control but I have not been able to get past the "visible" window problem.

This has been really puzzling me.
I have a windows services, written in c#.
What I'm trying to do now is to force single-threaded apartment.
So here's how my code look like:-
//Main Entry for Process
static void Main()
{
Thread.CurrentThread.ApartmentState = System.Threading.ApartmentState.STA;
}
When services starts, it will call this:-
protected override void OnStart(string[] args)
{
if (Thread.CurrentThread.ApartmentState == System.Threading.ApartmentState.STA)
{
EventLog.WriteEntry("SvcTest","Single Thread Apartment");
}
else
{
EventLog.WriteEntry("SvcTest",Thread.CurrentThread.ApartmentState.ToString());
}
To my surprise, it's still showing the CurrentTread.ApartmentState as "MTA" (Multi-Threaded Apartment).
Can someone explain this..  .

Try changing it to this:
[STAThread]
public static void Main()
{
}

Any help is greatly appreciated.
I've made a few changes.
<br />
[STAThread]<br />
static void Main()<br />
{<br />
Thread t = new Thread(new ThreadStart(WorkerThread));<br />
t.ApartmentState = ApartmentState.STA;<br />
t.Start();<br />
}<br />
<br />
static void WorkerThread()<br />
{<br />
ServiceBase.Run(new System.ServiceProcess.ServiceBase[] { new TestSvc() });<br />
}<br />
and in the onStart Method, when window services starts, it stills show
thread as MTA. I am just LOST... Unless, there is something I'm missing here.

I am new to C# and I am having some problem understanding arrays. I am getting the following exception:
An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll
Additional information: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.
The problem seems to be (string)ie.Current. I do not understand why I cannot retrieve the value. Any ideas would be appreciated.
