You can't just double click on the service's exe file for it to run. Either use he Services applet from the Administrative tools, or in your code use the ServiceController class.

Dear All,
I am using XFS API to send commands to ATMs. For example If I want to get the information of Receipt Printer, I am calling the following function..

public class XFS
{
[DllImport(@"msxfs.dll")]
public static extern int WFSGetInfo(ushort SPIHandle, uint Category, IntPtr QueryDetails, uint TimeOut, ref IntPtr result);
}

I want to know that what value of SPIHandle I have to pass.

[STAThread]<br />
static void Main(string[] args) {<br />
<br />
	Application.EnableVisualStyles();<br />
	Application.SetCompatibleTextRenderingDefault(false);<br />
	if(args == null || args.Length == 0)<br />
		Application.Run(new Form1());<br />
	else<br />
		Application.Run(new Form1(args[0]));<br />
}

args is the parameter list. if you open app through file the first parameter is the file name.. then you can do whatever you want with it..

"args is the parameter list. if you open app through file the first parameter is the file name.. then you can do whatever you want with it.. "

-what do you mean, i'm sorry i don't get it..in vs 2005 these lines are included in the Program.cs file, isn't it? These are my codes in my main form using the Form_Load Event.

RegistryKey rk = Registry.ClassesRoot.CreateSubKey(".sis",RegistryKeyPermissionCheck.ReadWriteSubTree);
rk.SetValue("Content Type", "application/x-sis");
rk.SetValue("PerceivedType", "file collections");
rk.SetValue("", "SIS");
rk.CreateSubKey("OpenWithList");
RegistryKey rk2 = Registry.ClassesRoot.CreateSubKey("SIS", RegistryKeyPermissionCheck.ReadWriteSubTree);
rk2.SetValue("", "SIS File");
rk2.CreateSubKey("DefaultIcon",RegistryKeyPermissionCheck.ReadWriteSubTree);
try
{
RegistryKey rk3 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("DefaultIcon", true);
rk3.SetValue("", "C:/sis.ico");
RegistryKey rk4 = Registry.ClassesRoot.OpenSubKey("SIS", true);
rk4.CreateSubKey("shell", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk5 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true);
rk5.CreateSubKey("open", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk51 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open", true);
rk51.SetValue("", "Open with &SIS");
RegistryKey rk6 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open",true);
rk6.CreateSubKey("command", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk66 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open", true).OpenSubKey("command", true);
rk66.SetValue("", "C:/SIS.exe");
RegistryKey rkapp = Registry.ClassesRoot.OpenSubKey("Applications", true);
rkapp.CreateSubKey("SIS.exe", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp2 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true);
rkapp2.CreateSubKey("shell", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp3 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell",true);
rkapp3.CreateSubKey("open", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp31 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open", true);
rkapp31.SetValue("", "Open with &SIS");
RegistryKey rkapp4 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open",true);
rkapp4.CreateSubKey("command", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp41 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open", true).OpenSubKey("command",true);
rkapp41.SetValue("", "C:/SIS.exe");

-what these lines of code do are adding entries in the Windows Registry such as default icons, type of file, etc. I can't seem to connect them to be default to run on my application as it prompts access denied message and worst, i don't know how i would activate my application and loading the clicked or double-clicked file onto it.... PLEASE HELP ME, WHAT WOULD I DO???

I think you need the File Types Editor in your deployment setup project:

Seems you are already on the right track. Remember your application must open the file using the arg[0](path to your file) parameter from the Main method.

static void Main(strings[] args)
{
if (args.Length <> 0)
Open(args[0]);//implement Open
else
Application.Run(new Form1());

}

I would do the following:

1) For testing purposes use the setup project (Set Open as default etc) and confirm the registry entries created by your setup project. Confirm double-click works.
2) Use C# to update the registry - compare with setup project entries to confirm what entries you may be missing.

Best of luck!!

How to convert a '.bmp' image to '.jpg' and '.gif' directly(without using save dialog) using C#.NET?

Re: Image Format Conversion

Christian Graus14-Jan-07 19:18

Just call the Save method on teh Bitmap class, and convert it to what ever you want to save to. That is, tell it to save as jpg, and it will.

could you please send the code snippet for this and Is this the only solution? I mean, Is there any direct write method or something for the conversion from bmp to jpg? Please excuse if I'm wrong.

Re: Image Format Conversion

you can save the bitmap to a memory stream to convert it without writing to disc if you want

     <br />
System.Drawing.Imaging.EncoderParameters encoding = new System.Drawing.Imaging.EncoderParameters();<br />
encoding.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, Quality);<br />
MemoryStream ms = new MemoryStream();<br />
_Image.Save(ms, System.Drawing.Imaging.ImageCodecInfo.GetImageEncoders()[1], encoding);<br />
_reformattedImage = ms.FromStream(ms);<br />

This IS how you directly convert, you read from disc in one format, and save back to disc in another. There's a block of standard code you need that is in some MS samples, from memory, I don't thnk naming the file .jpg is enough. Check MSDN for a sample.

Matching an expression in a text file

I am facing problem of matching an expression in a text file using C# in ASP.NET. The expression used will look like: ((apple AND orange) OR (car OR lorry)). A text file will be use to search for those keyword matching with the expression given. Do any one has any idea of how to perform the matching for expression mentioned above?

Re: Matching an expression in a text file

Christian Graus14-Jan-07 19:19

14-Jan-07 19:19

Looks like you've been asked to write a parser. Is this for the entire file, or just a line ? Either way, you need to do your own code to break the expression into sections, then you can evaluate each easy enough.

I'd say you need to build a tree of expressons that you can then walk to see if you end up with a true result.

Hello all,
I'm looking for a "CheckedListBox" type control with two checkboxes for each item. I've seen one on another site for C++ but I'm not good enough to convert it or to write my own control. Does anyone have one or know where I can get one? I'm using Visual C# 2005 Express if it matters.

Images loading and preview

Werfu14-Jan-07 11:25

14-Jan-07 11:25

I'm currently writting an application and I need to load all images from a directory and display their thumbnails after. I'd need to change the preview list when the user click on another directory in the tree view, so I need to load those thumbnail fast. Currently I'm loading all those images one by one and I store them into an ImageList. I know this is not efficient and that the images stay open until the file handle is close. I'm worried about the possibility to run out of memory or of file handle if the garbage collector don't free those ressources soon enough. Do anybody have any idea how to handle efficiently images preview and loading in .Net 2.0? I've googled a lot, but didn't find anything doing it. In fast, I need an image viewer as fast as possible as I'm loading from memory card and other slow disk drive.

Any idea? Let's discuss about .Net image capabilties.
