In order to find out the number of records in a database table "table", use the SQL Command:
Select count(*) from table
In general, try to get familiar with SQL and what it can do for you. It can do a LOT more than procedural code.

I thought you guys might be able to help.
I am still undecided about J#. Can anyone explain why the code snippet below would work in J++ but not in J#. The code compiles okay but it cant find the text file to read from. Instad, the exception I catch is J# filenotfoundexception. The text file is in the right directory. Anyways, appreciate any help.
public static String[] getIndonesianwordList(String file){
String IndonesianwordList[] = new String[9];
try{
BufferedReader in = new BufferedReader(new FileReader(file));
String s;
int i = 0;
while((s=in.readLine())!=null){
StringTokenizer tok = new StringTokenizer(
s,DELIMITERS);
while(tok.hasMoreTokens()) {
String nextWord = tok.nextToken();
System.out.println(nextWord);
IndonesianwordList[i] = nextWord;//wordList.add(nextWord);
i++;
}
}
}
catch(IOException e){
System.out.println(e);
System.out.println("error loading array");
}
return IndonesianwordList;
}

Just a guess, but maybe J# requires a fully qualified path name for FileReader (e.g., "C:\temp\foo.txt" rather than "foo.txt").

I am creating a small application that will goto a specific directory, display its contents, etc - basically the window where the dir contents is displayed should have the same functionality as a normal explorer window :
i.e.
Drag/Drop
Listing/Sorting functions
Double Click to open
I assumed that this would be fairly simple, but after some surfing around it seems that is not the case at all.
Does anybody have any experience of this?

Well after a few hours of looking around I have come up with a grand total of nothing.
So I have started to write my own, so far so good, but I have encountered a stumbling block - I cant find any code to open a file given its path.
For example, I am trying to open the following file :
C:\skunkworks\directoryviewer\test.txt
Does anybody have any info on achieving this?
I have been looking through this article :
http://www.codeproject.com/csharp/csdoesshell2.asp[^]
But it all seems to much to simply open a file in whatever the associated application.

I have found a solution to the file opening problem I mentioned above, just incase somebody is searching these forums for a similar answer this is the code I used :
<br />
FileInfo launchfi = new FileInfo(strDocumentPath);<br />
Process proDocument = new Process();<br />
proDocument.StartInfo.FileName = launchfi.FullName;<br />
proDocument.StartInfo.WorkingDirectory = launchfi.Directory.FullName;<br />
proDocument.StartInfo.UseShellExecute = true;<br />
try<br />
{<br />
proDocument.Start();<br />
}<br />
catch<br />
{<br />
MessageBox.Show("Unable to open selected document. If this problem persists please contact your Administrator.", "Document Open Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);<br />
}

Hi there
Basically whats the avantage of .NET over Visual studio 6.0.Many Ppl say that Common language Specification is the Advantage.
Do they mean that a code writtern in VB .NET can be used in C#?
If so we can very well write a dll in VB, that can be used in VC++.
Plz make me clear on this stuff .
Thanks in adv.

the difference is mainly
1) common class library across languages.
2) class/object reuse across languages.
you can't do this is vb/vc++ - you can provide a dll interface, but thats at a function level, not an object level.
of course you can get the same results with vb/vc++ and some clever programming, but the whole point is the M$ have done it for you.
its all about productivity.

Hi I have just finished writing one. The core is in native unmanaged C, but I made a .NET class for it as well. The DLL is meant to be used in Mirc, but can be accessed from .NET as well. Reply so I can email it to you.

Hi!!!
i have created a custom text Box inherited from TextBox Class. When I drag 'n' drop it from toolbox to Form. It shoes wait cursor and nothing happens  . But creating at runtime works fine....any hints???
sorry for my bad English.

You may have included some code that causes an infinite loop or the like at design time. Check your code for anything that relies on something that only exists at runtime. You can then do some logic arounbd this checking for whether it is designtime or runtime.
if(!this.DesignMode)
{
this.DoSomething();
}
Let me know if you need more info.

Hi,
I am doing some owner drawn menus that are supposed to display when right clicking on a NotifyIcon in the Tray. This has lead me to discover these 2 issues...
1. You can't use the OwnerDraw property on menuitems that are added to the "ContextMenu" property of a NotifyIcon. When you do, the user defined "MeasureItem" and "DrawItem" events never fire so you end up with a blank menu. - I fixed this by switching to use the NotifyIconEx that I downloaded from this site, and all my menus work fine then.
2. When you call e.DrawBackground() in the DrawItem event of the menu it draws the correct highlight color, but it draws the background as "KnownColor.Window" instead of "KnownColor.Menu" when the item isn't selected.
Does anybody know anything about these 2 things? Anybody know any way to get this work correctly? Or are they already working correctly and I just didn't RTFM?
Cheers,
Chris.

Hi,
In what dll is stored the GET_X_LPARAM(GET_Y_LPARAM) macro from the win32 SDK?
It is declared in WindowsX.h, but in what dll it is located?
As for my custom caption form I need to get the non-client mouse coordinates and to override the wndproc and catch the WM_NCHITTEST message.
Thanks in advance!

Macros aren't "stored" in DLL's. Macros are simply code substitution constructs which allows you to substitute a block of code with a friendly name. In other words, when you compile a source file and a macro is encountered, it removes the macro name from the source location and places the macros code at that place and continues compilation. The macro itself, just like a comment, isn't located in the resultant binary file. You'll have to write your own version of it.

C++ macros are not located in DLLs, they are parsed at compile time.

Hi. I'm a C# newbie and I'm having a bit difficult time to understand using "this". For example:
public class DBBool
{
public DBBool(int value)
{
this.value = value;
}
.....
}
By using "this.value = .." to what do we assing the value and how will we use that value afterwards?

The this pointer is a reference to "yourself". Use it to access members (properties and methods) you inherited from other classes, and for a way to pass a ref of yourself to another object.
