I want to disable the xp or 2000 system hot key ,just like ctl+alt+del ctl+shift+esc ect. I use C#.

This article[^] describes what you are asking. It's in C++ though, so you would need to translate it to C#. Since it's just Win32 API calls, this site[^] would probably help.
Take care,

I'm trying to display the name of an application that a particular file extension is associated with
I'm successfully pulling the info out of the registry, but end up with the "shell\open\command" in a format such as
c:\progra~1\app\someapp.exe /a /b %1
or
c:\other\app\otherapp.exe
or
"C:\Program Files\Microsoft Office\OFFICE11\WINWORD.EXE"
or
"c:\program files\something else\wibble.exe" %1
etc
I just need to pull out the full path of the executable, so I can query it's icon - can anyone help?

Hi..
you don't need to find the path of the application that is associated with a certain filetype.
all you need is this struct:
[StructLayout(LayoutKind.Sequential)]
internal struct SHFILEINFO
{
public IntPtr hIcon;
public IntPtr iIcon;
public uint dwAttributes;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public string szDisplayName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 80)]
public string szTypeName;
};
, this api call:
[DllImport("shell32.dll")]
public static extern IntPtr SHGetFileInfo(string pszPath, uint dwFileAttributes, ref SHFILEINFO psfi, uint cbSizeFileInfo, uint uFlags);
and a function that looks like this one:
private Icon getIconForFile(string FileName)
{
Icon RetVal = null;
FileInfo inf = new FileInfo(FileName);
SHFILEINFO shinfo = new SHFILEINFO();
IntPtr hImgSmall = Win32.SHGetFileInfo(FileName, 0, ref shinfo,(uint)Marshal.SizeOf(shinfo),Win32.SHGFI_ICON |Win32.SHGFI_SMALLICON);
RetVal = Icon.FromHandle(shinfo.hIcon);
return RetVal;
}
simly call this function and you'll get the associated icon for your filetype 
hope this helps

I need the executable's name too (I display a list of applications, but wanted to display the system default one on top)

Hi
found this ( ([A-Z]:\\[^/:\*\?<>\|]+\.\w{2,6})|(\\{2}[^/:\*\?<>\|]+\.\w{2,6})) regex here[^]
it's supposed to extract the filename of your exe only without the parameters
greets

I need to change color of some of the text that will be appear on my static label - how can i do it ?
I know that i can use the Rich Text Control ... but i don't want to use the it.
Thanks.

To change only part of the text, you need to owner draw and write your own code for defining the colors of parts of the text.

Is there is no other way ?
Without writing my own code ?

OK - this is a developer site. Surely this is exactly the type of challenge you would want to rise to.
Deja View - the feeling that you've seen this post before.

My application is connected with access database called BaseStudents!
This database have table with name: tblSudents. The first field in table
tblStudents is "StudentID" type:number(long int) and also primary key,
second field is "Name of Student" etc...
So my problem is, when my application will insert some data in table 'tblStudents'
it would look like this:
StudentID Name
1 Jack
2 Tom
3 Mike
4 Peter
5 Paul
6 Maria
7 Jean
8 David
9 Jesse
10 Vik
11 Alex
.....
Then, my application can delete from this table, but if someone
delete records with number: 2,3,4,5,6,7,8
the table 'StudentID' it would look like this:
StudentID Name
1 Jack
9 Jesse
10 Vik
11 Alex
Is there a way,when I delete records, the field 'StudentID'
to have a value: 1,2,3,4,5,...
I mean after deleting the table to look like this:
StudentID Name
1 Jack
2 Jesse
3 Vik
4 Alex
to renumber StudentID, to sequence number, not 1,8,9,10!
Second question:
I need help with select statement...
I know UPDATE,DELETE, INSERT, but SELECT with condition
like this(when I press button "Select", to execute code below)
"SELECT StudentID, Name, FatherName, LastName, years FROM [tblStudents]" + " WHERE Name=" +comboBoxName.Text+", FatherName="+comboBoxFatherName.Text+", LastName=" +comboBoxLastName.Text+", years=" +comboboxYears.Text+";";
So I want to select data who is equal from database tblStudents, and the data who user of my application
will pick from the comboBoxes.First, user pick value from comboBoxes, then press button "select"
and "selected" data should appear in dataGrid or dataView...
Is this correct?
Is this possible?
Please, if you have a free time and if you want to help me, reply to me...
All the best, from c# begginer to c# advanced...
sorry for bad english

I recommend you buy a book on SQL and work through it.
replace your , with the word AND, put quotes around the strings, and then it will probably work.
If you have SQL Server, read the books that come with it, they cover all this basic SQL stuff.

Buy a book or use Google. There are only about 1 million examples.

Hi,
Is there any good way to handle large file (typically 2Gig)? I prefer to read block by block and upload into GUI.
How it will work out ?
|
|

|

I think that you can read it fast enough with Streamreader. But I don't know what the results will be for your memory...
If you are intending to pass this info into a database. You might wanne create a Data Transformation Service
(DTS) package for the (bulk) insert. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dtsprog/dtspapps_21rn.asp
For the rest I want to suggest you, because you specified GUI, that while reading to a GUI, you don't update/redraw the GUI, because this will slow down the whole process. When passing them to a listview, the good way is:
listview1.BeginUpdate()
READ + ADD TO LISTVIEW1
listview1.EndUpdate()
Good luck, if not satisfied, please provide more details on your project.

If you're using a 32 bit version of windows, the maximum memory space for an application is 2gig (3 if you fiddle some system settings), so you might find you can't hold the whole file in memory

how to tranfer file using Filestream through sockets using UDP in c#..?
I've tried file streaming but at Recieving End i m unable to get the byte recieved in my recieving buffer as RecieveBuff.length() gives the length of buffer but not the total bytes recieved in buffer.
ForExample at rcving end length of buff is 8KB but if last sending packet is of 2KB then how Could I retriev just 2KB as it append the 6KB of garbag data into buffer.
SO PLZ HELP ME OUT ASAP.
Thanx.

I want to use connection pooling in my application.

Think in Datareaders. If you use it,you open, read and time after you close it. If in this period you try to open another from other thread you will get an exception.

Hi - this is actually the third time you came to this site asking the same question.
It looks like you really need to post to a Crystal Reports forum not a C# forum. Have a search on google to see what you can find.

If the OP who just deleted his post is still around - please don't delete above a thread - it messes up the forum.
I wasn't being unjust - I just didn't want you wasting your time asking the same question in the same place many times and not getting any results.
