using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Data.OleDb;
using System.Windows.Forms;
namespace WindowsApplication1
{
public partial class Reservation : Form
{
OleDbConnection cn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\intel\\Desktop\\DB.mdb");
OleDbCommand cmd;
public Reservation()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
cn.Open();
cmd = new OleDbCommand("insert into Table1 values('" + textBox1.Text + "','" + textBox2.Text + "')", cn);

What is the schema of the Table1 ?
It seems that you can insert into the table, but missing the field value for some additional required field.
insert into Table1 values('field1', 'field2', 'field3', ..., 'fieldn')
n = Table1's field's count

no caps until you have something special to say else it consider as you're shouting and nobody will reply you. Plus use Edit button at botton-right corner of the message to edit it.

try using square brackets around your column names. i.e. [Column1], [Column2] etc.
Also, do not include your AutoNumber column when inserting, this will be assigned automatically - you cannot write to it manually
third thing - make sure you use command parameters with your code...
cmd = new OleDbCommand("INSERT INTO Table1 ([column1], [column2]) VALUES (@1, @2)", cn);
cmd.Parameters.Add("@1", OleDbType.Char).Value = textBox1.Text;
cmd.Parameters.Add("@2", OleDbType.Char).Value = textBox2.Text;
NOTE how the column names have been specified to avoid trying to insert into the AutoNumber column

Hi
I have an application that contains a richtextbox with ole objects embedded into it.
The ole objects are imported from source files.
I am able to edit all embedded objects in their respective native applications except for powerpoint objects.
The powerpoint objects are activated as powerpoint slideshows and thus its not possible to edit these objects in native application.
Is it possible to change the default activation of ole powerpoint embedded objects from powerpoint slideshow mode to powerpoint presentation editing mode?
If not i also worked with the code (http://www.codeproject.com/KB/edit/richtextboxplus.aspx)
IRichEditOle richEditInterface = this.RichText.GetRichEditOleInterface();
// Create an object to hold info about the requested RTF object.
REOBJECT reObject = new REOBJECT();
IntPtr pPptObject = IntPtr.Zero;
richEditInterface.GetObject(0, reObject, GetObjectOptions.REO_GETOBJ_POLEOBJ)
// (You can get a GUID using the OLE/COM object viewer.
Guid guid = new Guid("{64818D10-4F9B-11CF-86EA-00AA00B929E8}"); // this is the GUID for powerpoint
// Query for the interface we want.
Marshal.QueryInterface(reObject.poleobj, ref guid, out pPptObject );
//i hope the following code typecasts the ole object (actually a powerpoint) into a powerpoint - but i have no clue of it
PowerPoint.Presentation ppt = (PowerPoint.Presentation)Marshal.GetTypedObjectForIUnknown(pPptObject, typeof(PowerPoint.Presentation));
Is it possible to use above code to activate this in powerpoint application editing mode?

Hi.
Can we run a C# App on a system without installing .NET Framework ?
Is it possible ?
Thank you.
|
|
|
|
|
well i assume you mean a C# App that uses the .Net Framework?
You could try copying the .Net Framework .DLL files that your app needs to its local directory and reference those files in your app. I think it is posible in VS or SD to set if a reference is a local copy or not. I not played with it thou so i cant be sure

You mean we can write a C# App without .NET Framework !
So, how ?
|
|
|
|
|
Well C# is just a language so.... i wouldnt know what to suggest you use it with thou. I have done game development with C# and XNA but i dont recall if it uses the .net framework thou.
Why is it you dont want end user machines to have .Net framework?
My suggestion would be just to include the .Net framework redistributable with your applications setup

no, it wont work. I tried that when I start programming, copied every known DLL in executable directory and got a nice looking .Net not installed error.

Try Xenocode Postbuild
Run your application on any Windows PC - Native x86 executable generation allows your .NET application to run anywhere, with or without the Framework. Embed application-specific .NET and DirectX dependencies. (Windows 9x and NT4 targets not supported.)
|
|
|
|
|
Alas, It's not free 
|
|
|
|
|
Depending on what you want to accomplish xenocode might not do what you want. IT doesn't actually convert your app into a native one. It wraps a compiler and the used parts of the framework into a single giant exe and then obfuscates them. At run time it then extracts everything and runs it just like a normal .net app.
Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

Hi John .
How do you do today ? 
|
|
|
|
|
Why would you want to do this? And in short, you can't. C# is very closely linked to the .NET Framework and you can't run C# apps without the framework although there are dubious products which claim you can.
The framework provides all the managed code support (garbage collection, verifiable code, reflection, security etc) for instance.

Rob Philpott.

Thanks Rob. I don't want to do that.
I've wanted to know.

Terrific , thank you 8kelvin

The best solution, put .Net Framework setup with your app. But if you want to run your app without .Net Framework then you should try or buy Xenocode Virtual Appliance[^]
