Then your ActiveX controls MUST close the files before the app exists. There must be some way of telling the ActiveX control to close it's files. If not, you're going to have to come up with some kind of shell around your entire app that waits for your app to close, then deletes the files...

The ActiveX control would most likely close the file handles while being disposed, so making sure the temp files are deleted after the ActiveX control is disposed would help.

You said it yourself!  most likely, but not guaranteed...
I say this because I've seen some crappy ActiveX controls come out of Novell that didn't clean themselves up properly.

He seems to be using the Office ActiveX controls which would close the file handles. Like you said, though, there are crappy ones out there that don't. From Novell I don't doubt that!

With their networking protocols and the like, yes. I just don't like them and with Active Directory and *nix-based networks dominating the market, I can't believe Novell is still around. I guess they think that clinging to open-source will save them. Nothing like jumping on the bandwagon...until it falls off a cliff! Bwahahahaha!

On top of all that, it still needs a DOS partition to boot and still relies on 16-bit code in it's kernel.
Won't be fixed until NetWare 8 with a complete rewrite of the kernel, if the company survives that long...

You'll have to use the Microsoft Office PIAs (Primary Interop Assemblies). If you are using Office 2002 (XP), you can download them from http://www.microsoft.com/downloads/details.aspx?FamilyId=C41BD61E-3060-4F71-A6B4-01FEBA508E52&displaylang=en[^]. If you're using Office 2003 Professional or Developer you can get these from the CD. They are not downloadable unless you're an MSDN Subscriber, though. In that case, however, you can actually use the XP PIAs because the supported interfaces are backwards compatible, at least for the functionality you need.
In your code, create a new instance of the ApplicationClass and use ApplicationClass.Workbooks.Open to open your file. You can then enumerate the Sheets property to get the name. Make sure to close the workbook and call ApplicationClass.Quit when done. If you design an effective caching system, you could save yourself a big performance hit by remembering which files have which worksheets if you know they won't change.

Hi,
Can we get the exe path using C# calls??
I am getting only the special folders path, (like program files, programs, etc). How to get the user created folder paths??
Thanks and Regards,

Hi,
I have started the application like this in a Service called myservice.
Process myapp=Process.Start("application path");
Now I want to get the application path (which is hard coded) through the program.
With myapp how to find out the path of the exe.

Hi,
Sorry I think my question is not clear.
I have some process which starts some exe's.
Now I am hard coding those exe's names.
What I want the program should get the complete path of the exe and start those exe. Because these exe can be installed anywhere, If I hard code it creates problem. As you said Environment.CurrenDirectory it gives only the process's current directory not the exe's directory which I want to start.
Is there any way to get that path of exe.
Thanks and Regards,
Satya Prasad.

You need some way of determining where those .EXE's are? Did you install them as part of your package? If so, then you could generate an .INI file listing the locations of the .EXE's. Your service could then read that .INI file to get the path to the .EXE's you want to launch. If not, your going to have to come up with a way to find these .EXE's and create an .INI file that can be used by your service. Possibly asking the user where they are? Or writing code to hunt them down? It's up to you...
Another method, although less reliable and surely more problematic, would be to write code that searches the drive for the .EXE names you want, then launch them. I think you can see the security and reliability problems with that approach...

When executables are in directories listed in the PATH environment variable, they can be executed without specify a directory. If they aren't in the path (including the current working directory), then you need to know where they are up-front like Dave said.
If the executable is in the PATH and you still want the full path, use Environment.GetEnvironmentVariable for "PATH", then use String.Split to split the paths into a string[] array using ";" as the delimiter. You can then search those paths in order to find all the paths to the executables.
If they aren't in the PATH, then you should either store the paths in the registry or some common file during installation, or creating an RCW (Runtime Callable Wrapper) around the MSI runtime (if you used Windows Installer for your installation of these programs) and query for the executable's component path.
There's no automagical way to get this information.

Hi,
since now I used sonething like this:
System.IO.FileInfo fi = new System.IO.FileInfo(Application.ExecutablePath);
GlobalContainer.ExecutablePath = fi.DirectoryName;
fi = null;
Help states:
Property Value
The path and executable name for the executable file that started the application.
Caveeat: You need to reference System.Windows.Forms.

Hello,
I have added the user control to a form. How do I listen for form resize event inside my user control. i.e When ever form is resized, i need to resize the user control also. I dont want to use docking property of user control.
I tried with the below statement:
private void InitializeComponent()
{
//.........
this.TopLevelControl.Resize +=new EventHandler(TopLevelControl_Resize);
}
But this is throwing NullRefrenceException - Object reference not set to an instance of an object.
Is there any other way?
Thanks & Rgds

Try the Anchor property of the control.

Hello,
Anchor property does not resize the control and location is getting changed.
Here i want control to be resized along with the form. When the form is resized larger and once control reaches its default size then control should stop resizing.
Thanks & Rgds

Wanna bet?
That's exactly what the anchor property does. It anchors one of more sides of the control to the side of its container, in your case the form.
If you select all four sides of the Anchor property, then the controls top left corner will be pinned in place and the bottom right corner will be moved to keep the same distance from the bottom right corner of the form. If you select just the top and left sides, then the control will maintain its position and not resize. If you select just the bottom and right sides, the control will not resize but will only move to keep it's position relative to the bottom right corner of the form.
The bottom line is if you select two opposite sides to Anchor, the control will resize itself to maintain those two edges relative to the sides of the form. If not, then the control will move to maintain its relative position to the edge that is selected.
To get the minimum size, use the MinimumSize property of the FORM, not the control. This way your form cannot be resized so small that the controls on it get so small that they are useless.
Your only other alternative is to override the Anchor property of the control and supply the resizing code yourself. BTW: What do you mean by "reaching it's default size"? The control can resize, but only within a certain range? Does it have to maintain a minimum and/or maximum size? If that is the case, then you WILL have to override Anchor and supply the resize code yourself.

Thanx Dave. It's resizing when form is resized.

You can also use the Dock property with DockStyle.Fill besides anchoring, but Dave's right - anchoring is used for this very purpose and gives you more control than docking in many cases.

I'm looking for a design pattern that allows for volatile interface changes to meet the needs of varying demands. Basically I have a project where abstractions will be relatively stable but, the actual implementations will vary. I've thought about using the bridge pattern but, I'm not sure if thats the best idea. If anyone has any suggestions they would be greatly appreciated.

I have seen some .NET code on the web that uses the Microsoft.Win32.Win32Native class. However, whenever I try to use it I get a compiler error (#CS0122) saying that it is inaccessible due to its protection level. How can I get access to it?
Thank you,
Ray Gregory
