Hey,
This is my first post here, I am trying to find the name of a program given a .exe file.....I have been banging my head against this for the last few days and am alomst going insane.
Any help would be appreciated.
I have the full path of the file eg c:/windows/sample.exe and from this i am trying to get a program name that I can output for a user to see.
Cheers

The simple answer is that you cannot.
What you see in the Start Menu and on icons in the Quick Launch bar and Desktop are the result of shortcuts (.lnk files)
If you are the author of the programs then you can write a mechanism that will expose a user friendly name, otherwise there is no consistent or reliable way to do that for third party applications.

Firstly, thanks for the quick response.
But surely, there must be a way.
I have retrived the icon using SHGetFileInfo() in shell32.dll, i have a full path name, etc...
Where and how, for instance, does XP get the description field in file properties when you right click on a file, or in this case executable? I know this information is only stored when running an NTFS, but even that would be a start.
Or where does the value for the registry entry in MUICache come from? I tried searching the registry for a reliable location, without any luck.
????
Thanks from,
Slowly going insane.....

There is a way, but keep in mind that it may not be the actual application title. That is set by the application at runtime only and it could be hard-coded into their source, grabbed from a resource string, or just about anything else.
Some of the information displayed in a file's properties (in the "Version" tab for an executable) can be obtained from the FileVersionInfo class like so:
FileVersionInfo info = FileVersionInfo.GetFileVersionInfo(
"%SystemRoot%\notepad.exe");
Console.WriteLine(info.ProductName); See the documentation for the FileVersionInfo class in the .NET Framework SDK for more information.

I need to serialize a COM object from the .NET environment. Can anyone help me?
|
|
|
|
|
That really depends on what interfaces the COM object implements. If it implements any of the IPersist* interfaces (IPersistFile, IPersistStream, IPersistStreamInit, etc.) then you need to declare those interfaces (the .NET BCLs already declare the IPersistFile and IStream interfaces as UCOMIPersistFile and UCOMIStream, respectively) where the methods are in the right order and the interfaces are attributed with the ComImportAttribute, the GuidAttribute (with the right IID of the interface), and the right InterfaceTypeAttribute (to declare it as an IUnknown, IDispatch, or dual interface).
You cast the COM object in managed code (assuming you have a reference to it in managed code) to one of those interfaces in order for the CLR to do a QueryInterface for that method. Then you call Load, Save, or whatever is appropriate and pass the filename, an IStream implementation, or anything else that is required by the IPersist* interface.

Hi,
Im trying to implement a function where a message will pop up, say a week before a particular expiry date and every day after that, until the expiry date..can anyone tell me whats the best way to go around this..and is there a namespace to make this function easier?

That is a bit vague. What is the mechanism for determining the expiry date. At what point is the message to pop-up? (Application start? Or is is supposed to sit in the background somewhere until it needs to display a reminder?)

What do you mean by this? Do you mean is there a class to make this easier? Perhaps the System.Threading.Timer[^] class would be helpful.

Hi,
I want to convert variables of type double to type float in my C# app.
I've read that casting from a double to float results in the double being rounded to the nearest float value. That is exactly what I need (as opposed to truncation).
However, I've also seen that the Convert.ToSingle(double) method uses rounding as well to convert the double to a float.
Is there any difference between these two techniques - casting and ToSingle? Are there scenarios in which one is preferable over the other? What about overhead?
Thanks!

I don't know technical point of this but from my personal expirience I ecourage everyone to use Convert.To... over casting because several times it happened to me that (casting) produced error and on contratry Convert.To... never made any trouble.

The basic difference is that a cast can thrown an exception which means anytime you cast something you should also wrap it in a try/catch block to handle any exception that is thrown. This in turn emits additional IL instructions, not much but it's there.

I want to create a secure Access-Database from C#.
I want to create a Database and a Systemdatabase - I suppose this works only in the same time.
Why does the following code not work?
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
ADOX.Catalog catalog = new ADOX.Catalog();<br />
catalog.Create("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=e:\\new.mdb;Jet OLEDB:System Database=e:\\new.mdw;Jet OLEDB:Create System Database=true");<br />
}
- it creates the e:\new.mdb but fails to create the e:\new.mdw.
the e:\new.mdb is not accessible.
I use Visual Studio 2003 and I have tried this
- on W2K with installed Access97 and Access2000 and
- on WXP with installed Access2003
All with the same result.

Hi,
In Visual c# 2005 Express, the code below will throw the following exception when accessing www.amazon.com. This does not happen in older versions of the .NET Framework. Why is this happening? Not sure what the violation here is. Using a different program, I can see that the returned headers by amazon.com look like this:

Why don't you try something like this:
private string GetHtml(string url)
{
WebRequest wreq;
WebResponse wres;
StreamReader sr;
String content = string.Empty;
wreq = HttpWebRequest.Create(url);
wres = wreq.GetResponse();
sr = new StreamReader(wres.GetResponseStream());
content = sr.ReadToEnd();
sr.Close();
return content;
}

That does not solve the problem. I still get an exception. It would solve it if casting the response would be the cause of the problem. It goes deeper than that into issues with GetResponse(). This is not happening in .NET Framework versions lower than 2.0
You need to DL the C# .NET 2005 Express to see this happening.

I have .NET 2005 running on my laptop, in fact here is a dump from a test program I wrote, which works fine.
#region Using directives
using System;
using System.IO;
using System.Net;
using System.Collections.Generic;
using System.Text;
#endregion
namespace Example
{
class Program
{
static void Main(string[] args)
{
Program p = new Program();
Console.WriteLine(p.GetHtml("http://www.yahoo.com"));
Console.Read();
}
public string GetHtml(string url)
{
WebRequest wreq;
WebResponse wres;
StreamReader sr;
String content = string.Empty;
wreq = HttpWebRequest.Create(url);
wres = wreq.GetResponse();
sr = new StreamReader(wres.GetResponseStream());
content = sr.ReadToEnd();
sr.Close();
return content;
}
}
}

yeah, i never said it doesn't work with every site. so far, i only noticed it happen on amazon.com. go visit http://www.amazon.com with your code. you'll see what happens. and the old framework does not throw any exception when i visit amazon.

There is nothing about the code that requires .Net 2.0 or Dev Studio 2005.
In any event, the code works for me under both .Net 1.0 and 1.1 against both yahoo and amazon. Are you sure you aren't trying to run this thing behind a firewall?
|
|
|
|
|
I have other reasons for using 2.0. This is just a sample. I know that you can access amazon and yahoo from 1.0 and 1.1.
Like i said, it is only 2.0 that is giving the problem.

I'd like to create some controls that have unusual shapes. i.e. Oval, Diamond, picture.
The problem is, all controls appear to be represented as rectangles.
How can I make a control a custom shape? There is no region or size map that I can see that determines what shape a control is, so where does the MouseOver event get it's information?
I was thinking of using some Region map to draw my control, and limit it's painting to that. But i'm not sure where to begin.
Failing this, i would have to create some kind of transparent control, but this leaves me with the problem of custom controls hiding controls they overlap with in transparent areas. I believe this is due to UserControls handling their own paint methods.
Any advice on where to start would be appreciated.

Use
GraphicsPath to definet the shape, then use control.Region to set the region shape.

hello,
My Web Service accesses to a MS SQL database to store and retrieve data from it.
but to store data, first I must to create programatacally the database and the tables. My question is what is the best way to do this? where is the best place to put the code which do this? In the beginning of each Web method (if the database and the tables do not exist, of course) or there is a common place to create or to initialize data, structures, systems, connections, etc.?
thanks in advance.
|
|
|
|

Actually, the best way to do it is to run the SQL script that creates everything either ahead of time, or when the Web Service is installed. Checking for the existance of the database on every call is very unecessary and just wastes time and resources doing the checks for something will only be done once.
