Hi!
1. It doesn't matter. You just have to look at the filename your source file gets - when you save it with "*.txt" as filter, Notepad automatically adds ".txt" to the filename. So if you save your source file as "HelloWorld.cs", you'll end up with a file "HelloWorld.cs.txt".
But for compiling the final filename really doesn't matter.
2. If you did, "csc.exe" will be found. If you didn't, it won't be found. Simple as that.
3. Then you'll have a VS.NET 2003 command prompt in your start menu. Use this to get the console window, then the correct paths will be set.
4. Putting source files on the desktop usually isn't such a good idea. Create yourself a dedicated source directory (C:\Sources, for example). This is far easier to reach, especially if you're using a command prompt.
Regards,
mav

Hi! I'm pretty new to C#, but, i wanna learn...
I have a question... i have a datagridview binded to a database, but i wanted to add also a delete column to erase that row. The problem is i can't find an event to trigger when i push the delete button. this would be the first part of the problem. the second problem is how do i know which row to delete when the button of one raw is pressed?(i would be regardful if u gave me some code examples, too).

Hi,
First of all, are you using asp.net or windows? If it is windows you can use the code below:
private void dataGrid1_Click(object sender, System.EventArgs e)
{
DataTable dt = dataGrid1.DataSource as DataTable;
if(dt!=null)
{
string firstField = (dt.Rows[dataGrid1.CurrentRowIndex][0].ToString());
}
}
As you can see, what I'm doing is casting the datasource datagrid's property to a datatable object. Then using the CurrentRowIndex property I can obtain any field's values from the datatable.
If it is an asp.net application, then you can use the code below:
private void DataGrid1_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if(e.CommandName=="Select")
{
string id = e.Item.Cells[1].Text;
Response.Write(id);
}
}
In this case, I'm assuming the ID of the row is presented in the second column (since the first one is the SELECT link).
I created a tutorial about GridView control (asp.net 2.0) at www.KYNOU.com. I'm always in this website's chat room. If you want to chat with me live logon to it.
I hope I helped

I feel really dumb asking this question, but I have spent about 5 hours searching for the answer to this, and have had little to no luck.
I am a completely newb coder to anything other than perl, so please take pity 
Basically I want to have a form with 2 text boxes and a button. (Got that part down :P)
Text box 1 is for the user to enter an IP address (Got that part too)
User clicks the button, and I need to run a "system"/"cmd"/"dos" command like so "nbtstat -A " + textbox1.text
then I need to read the results, parse out the MAC address make it show as textbox2.text
Any help would be awsome! Thanks!

If you want to wait for the process to stop before continuing the thread or forward stdio:
System.Diagnostics.Process p = new Process();
p.StartInfo = new System.Diagnostics.ProcessStartInfo("command", "arguments");
p.Start();
p.WaitForExit();
If you want to just start the process and move on:
System.Diagnostics.Process.Start("command", "arguments");
|
|
|
|
|
Process.Start() and its overloads are the way to create a new process. Which is exactly what you're doing with nbtstat -A. You can do something like:
Process.Start("nbtstat -A " + textBox1.Text);
The problem is, of course, getting the output from that. You won't be able to do it. So what you want to do instead is create a process like so:
Process proc = new Process(); proc.StartInfo.RedirectStandardOutput = true; proc.StartInfo.FileName = "nbtstat"; proc.StartInfo.Arguments = "-A " + textBox1.Text;
That tells the Process class that you want to redirect stdout so that it doesn't go to the console. After you do that, you can do this:
string output = proc.StandardOutput.ReadToEnd(); proc.WaitForExit(); textBox2.Text = output;
The docs mention that you have to call ReadToEnd() on the output stream before you call WaitForExit() because a deadlock condition could occur the other way 'round.And finally, put the output in textBox2. Just make sure textBox2 is a multiline textbox.
Once you wanted revolution
Now you're the institution
How's it feel to be the man?

Click the view details button, and show us some of that

Maybe the query didn't return anything.
Or try using a DataTable instead of a DataSet.

Hi,
Use interop to access the twain com object for this purpose:
[DllImport("twain_32.dll", EntryPoint="#1")]
If you want me to create a tutorial walking you through the process of using this technique, please send me a note through the website: www.KYNOU.com

Does anyone know if there exists a decent API that allows wrapping of the most common GUI APIs?
I'm not very comfortable with WinForms, but I can't switch to WPF yet. I'm considering writing my own widget system, or using wx.NET, but either way I'd like to keep as much of my code as possible - regardless of the underlying API.
The wrapper should have functionality for analyzing a WinForms designer.cs file and creating a common format XML file from it (preferrably XAML-oriented).
|
|
|
|
|
|
You mean as an intermediate description format? Yes, MyXAML would probably work. But I hope to find a wrapper that can act as a proxy API for (the most common features of) any GUI system.
I.e., when I create a ProxyAPI.Button, a button from the selected provider API will be created (be it WinForms, wx.NET, CEGUI, WPF or whatever).

Why not show "+" in TreeList?
My code:
TLNode tln1 = new TLNode(1, treeList1.Nodes, "name1", "123"); Ok!
treeList1.Nodes.Add(tln1);
TLNode tln2 = new TLNode(2, treeList1.Nodes, "name2", "123"); Ok!
treeList1.Nodes.Add(tln2);
TLNode tln3 = new TLNode(3, treeList1.Nodes[0].Nodes, "name3", "123"); not show
treeList1.Nodes[0].Nodes.Add(tln3);
TLNode tln4 = new TLNode(4, treeList1.Nodes[0].Nodes, "name4", "123"); not show
treeList1.Nodes[0].Nodes.Add(tln4);
public class TLNode : TreeListNode
{
String Title;
String Url;
public TLNode(int id, TreeListNodes owner, String title, String url) : base(id, owner)
{
Title = title;
Url = url;
}
...
}
Please help.

try inserting to the tln1 the tln3 and 4, and not to the treelist...
eg.

This code don't show all item
TLNode tln1 = new TLNode(1, treeList1.Nodes, "name1", "123");
TLNode tln2 = new TLNode(2, tln1.Nodes, "name2", "123");
tln1.Nodes.Add(tln2);
// treeList1.Nodes.Add(tln1);
TLNode tln3 = new TLNode(3, tln1.Nodes, "name3", "123");
tln1.Nodes.Add(tln3);
TLNode tln4 = new TLNode(4, tln1.Nodes, "name4", "123");
tln1.Nodes.Add(tln4);
And this code show 1 item "name1", and "+" don't show.
TLNode tln1 = new TLNode(1, treeList1.Nodes, "name1", "123");
TLNode tln2 = new TLNode(2, tln1.Nodes, "name2", "123");
tln1.Nodes.Add(tln2);
treeList1.Nodes.Add(tln1);
TLNode tln3 = new TLNode(3, tln1.Nodes, "name3", "123");
tln1.Nodes.Add(tln3);
TLNode tln4 = new TLNode(4, tln1.Nodes, "name4", "123");
tln1.Nodes.Add(tln4);
My be write same code for me, please. I don't know how to do this.
I have VS 2005 + MSDN(+DevExpress) but i am russin. My english is weak(feeble).

May be my class have error?
public class TLNode : TreeListNode
{
String Title;
String Url;
public TLNode(int id, TreeListNodes owner, String title, String url) : base(id, owner)
{
Title = title;
Url = url;
}
public override string GetDisplayText(object columnID)
{
return Title;
}
public override void SetValue(object columnID, object val)
{
DevExpress.XtraTreeList.Columns.TreeListColumn id = (DevExpress.XtraTreeList.Columns.TreeListColumn)columnID;
switch (id.AbsoluteIndex)
{
case 0:
val = Title;
break;
}
}
public override object GetValue(object columnID)
{
DevExpress.XtraTreeList.Columns.TreeListColumn id = (DevExpress.XtraTreeList.Columns.TreeListColumn)columnID;
switch (id.AbsoluteIndex)
{
case 0:
return Title;
default:
return "";

}
}
SetValue have stop point and debuger don't go in this metod after end edit.

Well, as far as I know, a time with the format HH:mm will give you time in 24-hour format, like 20:05 for example for 08:05 PM. It looks like the M of AM and PM is mistakenly perceived as the M of month. Try putting hh:mm and see what happens. That's all i can think of from the information you gave.
