 Hi, I am new to C# and programming in Windows Forms.
I use DataSet.ReadXml and DataSet.WriteXml and Save and
OpenFileDialog to get the filename. I want to save and read some data from the path that the program starts.
In my previous programming language I could easily get the path of the exe file, however Directory.GetCurrentDirectory returns the path that I most recently used in the FileDialog. Is there a Function that returns the path at start of the process (program)

Hello,
I've read the following article:
http://www.codeproject.com/csharp/globalhook.asp
The code is working very well except for the problem the author mentioned:
Question:
I have a long delay when closing applications using hooks by clicking the x button in the titlebar. If I close the application via another event (button click) for example, that works fine.
Answer:
It's a know bug of Microsoft. It has to do with the Windows themes. If you disable the Windows themes, the problem goes away. Another choice is to have the hook code run in a secondary thread.
Can anyone tell me how can I 'have the hook code run in a secondary thread'?
I would really appreciate your help. Thanks.

Thanks for the reply.
Actually I want one way communication. ie I want to send commands to a dumb hardware which can only receive IR command and perform accordingly.
like a TV.
the hardware is a switcher.
here the connection is not established as the switcher can't reply back.

Try the static method Type.GetType(string). It will return a Type object that you can manipulate using reflection. I don't know if there is an easy way to do what you want to do. I will research it.

Sorry, I thought this would work but it doesn't. I will leave it here in the hopes that it might spark an idea on how to do it.
string stype = "System.Int32";
Type t = Type.GetType(stype);
IConvertible converter = (IConvertible)t;
object obj = converter.ToType(typeof(int), CultureInfo.InvariantCulture);
int i = (int)converter.ToType(typeof(int), CultureInfo.InvariantCulture);
InvariantCulture is a static property defined in the System.Globalization.CultureInfo class.

You're half way there cap'n, you need to use Activator.CreateInstance on that Type object obtained using Type.GetType

Thanks! I knew that, I just couldn't remember

Hi,
In my Bin's Release folder (C# Windows project .NET 2.0), I see two identical files have been created,
1] MyProjectName.exe.config
2] MyProjectName.vshost.exe.config
I understood that, MyProjectName.exe.config is the output version of App.Config file, but what is MyProjectName.vshost.exe.config and why is that required ? If I dont ship that file to my user's computer, will there be any problem for running the software properly ?

Thanks a lot. I got my answer

Well a quick search on google brought me this:
By default every time you compile a WindowsApplication or ConsoleApplication project using VS2005, a "vshost.exe" and a "vshost.exe.config" files are created on the \Bin\Debug and \Bin\Release paths.<br />
<br />
The purpose of these "vshost.exe" and a "vshost.exe.config" files is described <a href="http://msdn2.microsoft.com/en-us/library/ms242202(VS.80).aspx">here</a>[<a href="http://msdn2.microsoft.com/en-us/library/ms242202(VS.80).aspx" target="_blank" title="New Window">^</a>].<br />
<br />
To disable this feature you need to:<br />
<br />
Open a project in Visual Studio. <br />
On the Project menu, click Properties. <br />
Go to the Debug Tab <br />
Clear the Enable the Visual Studio hosting process check box.<br />
<br />
Another common question is if we need to deploy these files and the answer is No, the "*.vshost.exe" and "*.vshost.exe.config" files are only for use in the Visual Studio 2005 IDE<br />
<br />
Pablo
Short answer? no you don't need to ship this out with the app, at least im pretty sure anyways...
Damn, beaten to it... ah well

Hi guys,
This activex control has optionals parameters for GetData method:
this.axWinsock1.GetData(ref object data,object type,object maxlen)
i tried these:
object rec= string.Empty;
object type = 0;
object maxlen = 0;
this.winsock.GetData(ref rec, type, maxlen);
or
object rec= string.Empty;
object type = string.Empty;
object maxlen = string.Empty;
this.winsock.GetData(ref rec, type, maxlen);
but all i get is "Unsupported variant types" error message, do you know how to call this getdata method in c#? i know if you call it in vb.net you dont need to pas optional parameteres.
Please help

You might be able to pass a null value as the optional parameter. Alternatively you might want to look at the System.Net.Sockets class of the framework which does essentially the same thing except that it's more powerful and it's the proper .NET way of reading and writing data across Sockets.
Sig cops got me...
