Hi,
Just Install the .Net Framework ver(in which ur app is developed) on the m/c where u want to run ur App...........

Hi,

I created a simple application in C# using .NET visual studio. The release build seems to work just fine on my development machine but it does NOT seem to work on my "non-development" machine (a clean W2k machine with no visual studio .net). By the way, I was using the default release build setting to create the exe.

I get error complains such as "mscoree.dll is missing". When I provide this mscoree.dll it cries about some registry key not setup to point to the install path etc. etc.

Any idea, suggestion, help?

Thanks!

This seems to be a common question again. If you developed your application using C#, VB.NET or Managed C++, you need the .NET Framework. You can't just redistribute parts of it - you need the whole 20MB package. Download the redistributable here[^]. Windows Server 2003 includes .NET Framework 1.1.

I don't think this download currently contains Service Pack 1. It's advised that you apply this service pack. Download here[^] (or here[^] for Windows Server 2003).

If you want to install the .NET Framework along with your application, see Microsoft's Setup Bootstrapper Sample[^].

Greetings, I have a datagrid in a parent form that created a child form when one of the cells in the parent form is double clicked, a dataset is then passed to the child form in the constructor. With that dataset, I'm creating a new datagrid. When I try to set the column width values or capture a MouseDown event, it seems as though the Child Form is ignoring all attempts and defining events and column width values. The same code works fine for the parent form; any thoughts?

--Mike

Normally this should function properly. Without any further details I dont think anyone can help you. If it isnt too much you should post the relevant parts of your code.

Okay, I call the new form passing it a dataset. In the new form, I call a method to initialie the datagrid; here is that code. The Alternating back color, the mousedown events, and the column width seem to be ignored. Seems like I'm missing something simple here:

The steps I'm taking in the constructor of the new form are:

public ClientActivity(DataSet ds)
{
//
// Required for Windows Form Designer support
//
this.gridMouseDownTime = DateTime.Now;
this.ds = ds;
this.WSID = WSID;
InitializeComponent();
InitializeDataGrid(ds,WSID);
//
// TODO: Add any constructor code after InitializeComponent call
//

}

private void InitializeDataGrid(DataSet ds)
{
try
{
//AddCustomDataStyle(ds);
dataGrid1.DataSource = ds.Tables[0];
dataGrid1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.dataGrid_MouseDown);

int rowCount = ds.Tables[0].Rows.Count;

DataGridTableStyle tableStyle = new DataGridTableStyle();
tableStyle.MappingName = "ClientActivity";
tableStyle.AlternatingBackColor = System.Drawing.Color.Gold;
//tableStyle.BackColor = System.Drawing.Color.White;
tableStyle.GridLineStyle = System.Windows.Forms.DataGridLineStyle.Solid;
tableStyle.GridLineColor = Color.Red;
tableStyle.SelectionBackColor = System.Drawing.Color.Blue;
// tableStyle.SelectionForeColor = System.Drawing.Color.Blue;

int numCols = ds.Tables[0].Columns.Count;

DataGridTextBoxColumn aColumnTextColumn ;
for(int i = 0; i < numCols; ++i)
{
aColumnTextColumn = new DataGridTextBoxColumn();
aColumnTextColumn.HeaderText = ds.Tables[0].Columns[i].ColumnName;

aColumnTextColumn.MappingName = ds.Tables[0].Columns[i].ColumnName;
//add handler
//MessageBox.Show(ds.Tables[0].Columns[i].ColumnName);
aColumnTextColumn.TextBox.MouseDown += new MouseEventHandler(TextBoxMouseDownHandler);
aColumnTextColumn.TextBox.Width = 100;
aColumnTextColumn.TextBox.DoubleClick += new EventHandler(TextBoxDoubleClickHandler);

tableStyle.GridColumnStyles.Add(aColumnTextColumn);
}

label1.Text = label1.Text + " For " + WSID;

dataGrid1.TableStyles.Add(tableStyle);

}
catch (Exception e)
{
MessageBox.Show(e.StackTrace);
}

}

First of all:
Happy new year!

Now to your problem:
I think you are not setting the right mapping name for the tablestyle
Instead of

<br />
tableStyle.MappingName = "ClientActivity";<br />

you should write

<br />
tableStyle.MappingName = ds.Tables[0].TableName<br />

Explanation:
A Grid can show multiple DataTables (eg. when showing a dataset). Thus you can also add multiple TableStyles (foreach DataTable). The MappingName is used to identify to which DataTable the TableStyle is bound. When the DataGrid shows a DataTable and cannot find a TableStyle (like in this case) with the appropiate MappingName it shows it with automatically generated style settings.

Hello all!
As I understand, static object pointers are considered root of the application and for that reason they are never removed by the Garbage collector.
Is there any way to force the GC to remove those elements?
Thanks

That would sort of change the static nature of static objects, no? Alot of things would break if you could do what you're asking.

Charlie

if(!curlies){ return; }

Not automatically. And this is very good as it would break the underlying paradigm.
You can set static members to null. The GC will then remove the underlying object from memory.

Iam working with an pocket pc application in .NET Compact framework and run it the emulator. I dont know where the EXE and other application files are stored in that emulator.

Sridhar

Can u please tell me where can i find the emulators ??? I also need them

If you install .NET 2003 you can get the emulator. it has an in build emulator.

sdaf

They will be stored this way(i assume the Emulator is english): \Program Files\[Project Name]\[App.exe]

Google: "Windows CE X.X emulator" to all the others looking for a emulator.

Hi,

What model/make of Pocket PC cum mobile phone would you recommend to buy for experimenting the .NET for devices as well as to use it as a mobile phone..

Please help

i can defenatly recommend the NeoNode: www[dot]neonode[dot]com

There is also a "non-official" forum for this phone at: www[dot]redneo[dot]com

It is running Windows CE 5.0

You should know that this phone isn't fully developed yet, but the NeoNode team are releasing updates etc. very often.

Please, how should I read and display thousands items on ipaq and I dont want to encounter performance issue. Reading and displaying with the help of dataset and datagrid seems to be slow.

Thx

What do you mean with thousands? Even on a smart device a few thousand items should be no problem. If you have really many thousand (or million) items the DataGrid isnt probably the best choice for you (because it always holds the whole data - not only what is shown). Have a look at http://www.devage.com/SourceGrid/SourceGrid2_EN.html. There youll find a free grid with a virtual mode (which means that only the data which is displayed is hold in memory) which is also available for the compact framework.
For reading your data I cant give you any hints because that depends on how your data is stored (DB, XML, ..)

The .NET Framework 1.1 install fails when regsvcs.exe attempts to register System.EnterpriseServices.dll.

it will install on Windows NT with Pentium 3 processor, but not on Windows NT with Pentium 4 processor.

The necessary prerequisites are installed - ie SP6a and IE6 SP1.

thank you

Hi all, I am a little confused by the static function GetType(string) of Type.

if I pass in "System.Int32", it will return a type, but if I pass in "System.Windows.Forms.Button", it will return null, but if I pass in "System.Windows.Forms.Button, System.Windows.Forms, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
it works a again.
The document didn't mention I must supply a strong name. Is there anyway to make it work with name like "System.Windows.Forms.Button"?

Here is a small test code

static void Main(string[] args)
{
Test("System.Int32");
Test("Int32");
Test("System.Windows.Forms.Button");
Test(typeof(System.Windows.Forms.Button).AssemblyQualifiedName);
Test(typeof(System.Windows.Forms.Button).FullName);

}
static void Test(string s)
{
Console.WriteLine("typename : {0}",s);
Type t = Type.GetType(s);
if(t!=null)
{
Console.WriteLine("GetType succeeded");
Console.WriteLine("Fullname : {0}",t.FullName);
Console.WriteLine("AssemblyQualifiedName : {0}",t.AssemblyQualifiedName);
}
else
{
Console.WriteLine("GetType failed");
}
Console.WriteLine();
}

Thx!

I would have thought it also works with normal names. There is another way to get a type. If you already have the adequate assembly object you could use:

<br />
System.Reflecten.Assembly a = System.Reflecten.Assembly.GetAssembly(typeof(Label));<br />
Type t = a.GetType("System.Windows.Forms.Button");<br />

Thanks!
