I am using Iexpress.exe to package all installation files(setup.exe,msi,.net framework etc) into single exe.

But the exe is not working.

I have created a batch file including following:
@ECHO OFF
CLS
MD dotnetfx
MOVE /-Y dotnetfx.exe dotnetfx
MOVE /-Y instmsia.ext dotnetfx
MOVE /-Y WindowsInstaller-KB893803-v2-x86.exe dotnetfx
EXIT

And selecting batch file,setup.exe and msi file in iexpress.exe for creating package.

Got the single exe but while installation i am getting:

This installation package could not be opened. Verify that the package exists and that you can access it or contact the application vendor to verify that this is a vlaid windows installer package.

And InstallLog file shows:

{
string siteUri ="http://utptt-ex.petronas.com.my/studentInd.htm";
webrequest wr= webrequest.create(siteUri);
return wr;
}

But i have some bugs. Is there anyone who has better codes to this?

I think you might be trying this using HTTP over TCP/IP.. If so then you need to hit an uri with some parama..and retrieve the acknowledgment.

HI
I am developing a .NET MyLib.dll to be exposed via COM to Excel.
In It there is a class called MyDotNetClass ( ComVisible is set to ture
and I have GUID attributer )
When I pass a Range to my AnyMethod and I want to get the FormulaR1C1Local
everything is thine.
When I want to call other method other than this ( including the getValue to get
the real valu conatined by the cells in that range, not its formula )
I have a lot of exception most of the same time.
Can you help me with that?
I already have a reference to Microsoft.Office.Interop.Excel library V12.0
for Excel 2007.

Thanks

Current directory problem in MDI container form

mutpan10-Sep-09 20:58

10-Sep-09 20:58

Hi All,

I am creating one MDI application using C# in VS 2008. I attached the code below. I open one RTF file through the Open menu of the main form using Open dialog and loads the file in to the rich text box present in the child form. My problem is before loading the file in to the child form, the current directory points to the Debug folder of the application, but after loading the file in to the child form the current directory changes to the file directory which I opened in the child form.

For example,
before loading the file, my current directory is : "C:\Sample\Debug"
after loading the file, it changes to : "C:\ArchiveFiles"
because i opened a file from the "C:\ArchiveFiles" directory.

It is the intended behaviour of the MDI application. How do avoid changing the current directory? I want the current directoy should always point to the directory from where the EXE is running.

Is there any way to do this?

namespace WindowsFormsApplication1
{
  public partial class Form3 : Form
  {
    Form4 f4 = null;

    public Form3()
    {
      InitializeComponent();
      this.IsMdiContainer = true;
      f4 = new Form4();
      f4.MdiParent = this;      
      f4.Show();

      // Current directory here points to the debug folder
      string ctDir = System.Environment.CurrentDirectory;
      
    }

    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
      if (DialogResult.OK == openFileDialog1.ShowDialog())
      {
        f4.OpenFile(openFileDialog1.FileName, this);        
      }

      // Current directory here points to the directory which you opened file from open dialog 
      string ctDir = System.Environment.CurrentDirectory;
      MessageBox.Show(ctDir);
    }
  }
}

public partial class Form4 : Form
  {
    public Form4()
    {
      InitializeComponent();      
    }

    
    public void OpenFile(string filename,Form  parent)
    {
      richTextBox1.LoadFile(filename);
    }
  }

Thanks in advance,
Mutpan

i don't know why you want to get current Directory.
so you can try these.
1) you can use:
System.IO.Directory.GetCurrentDirectory();
AppDomain.CurrentDomain.BaseDirectory;
Application.StartupPath
AppDomain.CurrentDomain.SetupInformation.ApplicationBase
Application.ExecutablePath
and so on.
2)
you can save the CurrentDirectory Path to a string at the first time you get it .
and send to the other form when you open it.

hello
if i am using simple combo box on the form the Draw item event appear and i use code on this event is

private void cmbboxClr_DrawItem(object sender, DrawItemEventArgs e)
{
Graphics g = e.Graphics;
Rectangle rect = e.Bounds;
if (e.Index >= 0)
{
string n = ((ComboBox)sender).Items[e.Index].ToString();
Font f = new Font("Arial", 9, FontStyle.Regular);
Color c = Color.FromName(n);
Brush b = new SolidBrush(c);
g.DrawString(n, f, Brushes.Black, rect.X, rect.Top);
g.FillRectangle(b, rect.X + 110, rect.Y + 5, rect.Width - 10, rect.Height - 10);
}
}
-----------------------------
and at form load event i use code

Type colorType = typeof(System.Drawing.Color);
PropertyInfo[] propInfoList = colorType.GetProperties(BindingFlags.Static | BindingFlags.DeclaredOnly | BindingFlags.Public);
foreach (PropertyInfo c in propInfoList)
{
this.cmbboxClr.Items.Add(c.Name);
}

-------------------------------
and at select index change i use the code
private void cmbboxClr_SelectedIndexChanged(object sender, EventArgs e)
{
string color = this.cmbboxClr.SelectedItem.ToString();
this.panel1.BackColor = Color.FromName(color);
}

this will do but when i use toolstripcombo i'm not getting event Draw Item how can i achive the same thing using toolstripcombo my main problem is to access system colour patern along with name to change font or background colour

Re: access font colour paterns in ToolStripCombo box Along with name

Henry Minute11-Sep-09 9:09

AFAIK the ToolStripComboBox does not have OwnerDraw capability. In fact most of the ToolStrip versions of controls are 'crippled' to some extend.

You might be able to save yourself a little processing and therefore make it a little faster by modifying your load event handler.

You could do something like:

foreach (string colorName in Enum.GetNames(typeof(KnownColor)))
{
    this.cmbboxClr.Items.Add(colorName);
}

in fact you can even shorten that to either of:

this.cmbboxClr.Items.AddRange(Enum.GetNames(typeof(KnownColor)));

// *************** OR ***************
this.cbbboxClr.DataSource = Enum.GetNames(typeof(KnownColor)));

I have not done any time comparisons for these suggestions, and so cannot say which, if any, is faster than your current code.

As far as the ToolStripComboBox problem is concerned, it has occurred to me that, you might (again I have not tested it) put a standard ComboBox on the ToolStrip. Take a look at this[^] for further details.

Accessing bytes in a video as it is playing in windows media player

I have put windows media player in a form, and was wondering if there is any way to see the bytes as they are being streamed to the viewer, so that I can manipulate them. I guess this would be like a buffering area where I can check the bytes and then play them.

Thanks

Didn't you ask this the other day ? I believe you can write what is called a 'pin' which gets inserted into the directX player sequence. If you can do this using WMP, I am not sure. But, that would be the only way to access the data as the player shows it, to have a flow of data in synch with the player.

Thanks again for you response, I did ask this the other day. I have found that typically the problem is that in forums, if you get one reply then people move on and look for ones that have no responses. Sorry though, I'll try to refrain from double posts here. I'll give the pin thing a try, thank you.
