In vb6 I used a the Heiricial grid control to display data. I have also used it in a few c# projects, but I do not like having to include the extra files in to the installation. Is there a way to use the standard datagrid to do this? The HGrid is easy to use as far as editing a record etc, and I would need the same things from a regular datagrid.
Thanks for your help

I have a windows form, whenever i click the button the app will start calculating. i need to schedule this app run everyday by using windows schedule task tool. The problem is when the app runs, the windows form opened but how i automatic fire button_click event so that the app can be run without my interaction. since sometimes user will need to run this app not at schedule time so i need to keep this button.
I am not sure anybody understand my situation but any suggestion is welcome.

I'm not that familiar with C#, so there's probably a better answer. The one that comes to mind for me though, is to put all the code from the button's click event into a separate function. That way you can call the function from the button's click event, or from anywhere else.
If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

The button_click event handler is just a method that conforms to the EventHandler delegate signature and can be called directly.
this.button_click(this, EventArgs.Empty);
Alternatively, you could move the code to a separate method, and call that method from both the event handler and whatever other code is necessary. This would be the prefered method if there is additional processing necessary depending on how the method is invoked.

I'm new to C#, so there's probably a better solution. But the easiest one I can think of is to put all the code from the button's click event in a separate function. Then call the function from the click event, and then also call it from the form's load event.

The System.Windows.Forms.Button class has a method PerformClick() that should do exactly what you want (if I understood your request correctly).
IIRC, PerformClick() doesn't create a click event when the button is disabled (that's what I'd expect).
Be careful when deriving from Button and setting ControlStyles.Selectable to false, though. In this case PerformClick() doesn't work either, even when the button is enabled.

 Hi, need to validate to see if the user is entering Half Width (Single Byte) Characters (Japanese KataKana) or Full Height (Double Byte) Characters and convert the string to either Single or Double Byte Characters as appropriate. And I need to do this in an ASP.NET application written in C#.NET.
I have tried using the
string x = "ｦ";
Console.WriteLine (Encoding.UTF8.GetBytes(x)); // always returns 2 bytes
UnicodeEncoding Unicode = new UnicodeEncoding();
byte[] bytes = Unicode.GetBytes( x);
Console.WriteLine( bytes.Length); // returns 2 bytes should be 1
foreach (byte b in bytes)
{
Console.WriteLine( b);
}
string str2 = "書";
byte[] bytes1 = Unicode.GetBytes( str2);
Console.WriteLine( bytes1.Length); // returns 2 bytes should be 2
foreach (byte b in bytes1)
{
Console.WriteLine( b);
}
What am I doing wrong, Any ideas anyone. I th
Thanks in advance

I check whether character entered by the user is of single Byte(hankaku) or Double Byte(zenkaku), using the following code.
public static int GetByteCount(string input)
{
int intByteCount =0;
System.Text.Encoding sjisEnc =
System.Text.Encoding.GetEncoding("Shift_JIS");
intByteCount = sjisEnc.GetByteCount(input);
return intByteCount;
}
You can input a single character and see the Byte Count using the above function as below:
string inputText = "西日本";
if(2 * inputText[0].ToString().Length = GetByteCount(inputText[0].ToString()))
{
System.Windows.Forms.MessageBox.Show("全角です。")
}
else if(inputText[0].ToString().Length == GetByteCount(inputText[0].ToString())))
{
System.Windows.Forms.MessageBox.Show("半角です。")
}
Though I do not know How to convert the Hankaku(Single Byte) Chars into ZenKaku (Double Byte)Chars and Vice versa?
I doubt, Whether it is possible to convert kanjis into single byte. Though english charactes written in Zenkaku(Double Byte) can be converted into Single Byte, Theoretically.
If You come up with the solution for the second[I mean conversion]. Please post it in the MessageBoard. It will be useful for others including me.
Do revert back, How far this could solve your problem.
Regards,
Jay.

Thanks I tried your code below and it has helped a lot
public static int GetByteCount(string input)
{
int intByteCount =0;
System.Text.Encoding sjisEnc =
System.Text.Encoding.GetEncoding("Shift_JIS");
intByteCount = sjisEnc.GetByteCount(input);
return intByteCount;
}
string inputText = "｡｢｣､･ｦｧｨｩｪｫｬｭｮｯｰｱｲｳｴｵｶｷｸｹｺｻｼｽｾｿﾀﾁﾂﾃﾄﾅﾆﾇﾈﾉﾊﾋﾌﾍﾎﾏﾐﾑﾒﾓﾔﾕﾖﾗﾘﾙﾚﾛﾜﾝﾞ 契約管理明細書ﾟ";
for (int z = 0; z < inputText.Length; z++)
{
if(2 * inputText[z].ToString().Length == GetByteCount(inputText[z].ToString()))
{
System.Windows.Forms.MessageBox.Show("全角です。- Double Byte " + inputText[z].ToString());
}
else if(inputText[z].ToString().Length == GetByteCount(inputText[z].ToString() ) )
{
System.Windows.Forms.MessageBox.Show("半角です。- Single Byte " + inputText[z].ToString());
}
}
If I get further with the conversion work I will post back to here.
Regards

I'm developing an application in VS.Net 2003 using C#, which uses Crystal
Reports.
My report connects to an Access DB.
Does anyone know how to reset the datasource at runtime? My app is currently linked to the datasource I specified at design time. This datasource will change once the app is installed on the client's machine.
Thanks.

Have you looked at the code in the C# sample from MSDN for Crystal Reports? I'm pretty sure the actual .rpt file changes at runtime for displaying which report, but I don't know about the actual datasource. I'm sure it has to be possible, because I know that most people making apps with CR aren't hard-coding the datasource names before distributing their apps. Anyway, if you haven't downloaded the samples, here's the link:

I am trying to figure out how i can make the generated typed datasets from VS 2003 us my dataSet base class instead of the System.Data.DataSet base class.
The generated code produce this:
public class AR_CustMaster : DataSet {}
I need the dataset generator to produce this:
public class AR_CustMaster : MyNameSpace.MyDataSet {}
I know i can go in the generated .cs file and manually change it but as soon as the dataset is regenerated, my changes are lost.
Is there any way to make the change permanent ?

When ur finished designing the dataset and u have it just as u want it, copy and paste the generated code to a new file. I dont think there is any other solution for what ur asking.

I am trying to format an integer to a string with leading zeros:
This works:
int i = 1234
Console.WriteLine("{0:0000000000}",i);
But what about make formats for new strings or saving in string variables ?
string strLine = new String("{0:00000}",i);
--> Cannot work caused by constructor parameter collision. By the way, var "i" is generic. So no solutions with constants and other literals.
Thanks for all advice in advance.

Ok, lets look under the hood of what works:
Console.WriteLine(string,params object[])
which you are calling internally calls
Console.Out.WriteLine(string, params object[])
Console.Out is a TextWriter instance, so:
TextWriter.WriteLine(string, params object[])
Internally this calls
String.Format(String,params object[] args);
so finally in answer to your question this will work:
string strLine = String.Format("{0:00000}",i);

The following code is part of my program:
<br />
string folderToWatch = @"d:\html\";<br />
FileSystemWatcher fsw = new FileSystemWatcher(folderToWatch, "*.html");<br />
<br />
fsw.Created +=new FileSystemEventHandler(OnCreated);<br />
<br />
fsw.EnableRaisingEvents = true;<br />
It works perfectly om my laptop running Windows XP SP2. But not at the server running Windows Server 2003.
Any suggestions why?
