I have a simple application that takes a folder path and open in the windows explorer.
Here is the code i use
Process p = new Process();
p.StartInfo.FileName = "explorer.exe";
p.StartInfo.Arguments = strFilePath;
p.Start();
The problem is that when the filepath contains spaces it works just fine on my xp machine but on my clients machine which use windows 2000 the application fthrows the exception filenotfound.
I would like to know why it works on xp and doesn't on windows 2000
|
|
|
|
|
try by this
...
p.StartInfo.FileName = "iexplorer.exe";
...

Have you tried wrapping the path with embedded quotes.
"\"path with spaces\myapp.exe\""

More generally, paste the exact string you send to the process class into the run dialog and see what happens there.

You can use this code:
private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)<br />
{<br />
Graphisc g = e.Graphisc;<br />
Bitmap bmp = new Bitmap("your_image.jpg");<br />
g.DrawImage(bmp, 0, 0);<br />
}

Except that it will leak resources. The Bitmap reading code should ideally read to a member variable ( why do it every time ? ), or at a minimum, should be in a 'using' block.

Can any one guide me how to launch the installed application immediatley after the Finished screen button clicked. Once the user clicks the finished screen "Close" button, i need to launch the installed application. I tried with installer class. Sample code is given below.I have created a class library and within that an installer class. I tried with the afterInstall event, but its not working.
namespace ClassLibrary1

[RunInstaller(true)]
public partial class Installer1 : Installer
{

InitializeComponent();

i have two form: Form1, Form2 and Form3. Form1 is MDI Parent form. i'v made Form2 to open when one menu is clicked from Form1. Now Form2 has one button which should show Form3, and i'v done the code this way:
Form3 frmF3 = new Form3();<br />
Form1 fm1 = new Form1();<br />
<br />
frmF3.MdiParent = fm1;<br />
frmF3.Show();
but clicking the button is performing nothing. how can i do that?
|

Dear,
Try to structure your code by doing the following:
-In form3 add the following Function:
public void Create(Form ParentWnd)
{
MdiParent = ParentWnd; Show();
}
- Now from Form2 do the follwing from a function of course:
Form3 form3 = new Form3();
Form ParentForm = this.MdiParent;
form3.Create(ParentForm);

Hi there
can someone please help me?
I want to select a row from form1 and then open another form (form2) which shows the same row but with some more fields...
so..
form 1. datagrid about 4 collums from the database table. then dubbel click on it
form 2. a couple of textfields.. (about 10) which shows all the records in the row.
i use C# winforms.
i've tried a lot of thinks but it just won't work....
|
|
|
|
|
Moddify the constructor of form2 so that it takes the ID of the row and then display the information you need.
On form1 make a event hanlder that will respond to the doubleclick on the datagrid and then make a new form in that event handler that will pass the id of the row to the form2.
Q:What does the derived class in C# tell to it's parent?
A:All your base are belong to us!

but how?
i actualy got al the coding.. but it just don't work.. and i really dont know why.
public void dataGrid_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)<br />
{<br />
int rowIndex = dataGrid1.CurrentRowIndex;<br />
if (CustomRow != null)<br />
{<br />
CustomRow(this, new CustomRowEventArgs(barry11,dataGrid1,rowIndex));<br />
}<br />
<br />
}
public class CustomRowEventArgs : EventArgs<br />
{<br />
<br />
public Barry1 DaSet;<br />
DataGrid grid;<br />
int row;<br />
<br />
public CustomRowEventArgs(Barry1 DSet,DataGrid Grid,int Row)<br />
{<br />
DaSet = DSet;<br />
grid = Grid;<br />
row = Row;<br />
<br />
}<br />
public Barry1 DSet<br />
{<br />
get { return DaSet; }<br />
}<br />
public DataGrid Grid<br />
{<br />
get { return grid; }<br />
}<br />
public int Row<br />
{<br />
get { return row; }<br />
}
that DaSet.. should be barry11 (my dataset) DaSet was kinne like a test or something..
or what variable or class or something should i put there..
public virtual void customHandler_CustomRow(object sender, CustomRowEventArgs e)<br />
{<br />
Barry1 DaSet = e.DaSet;<br />
DataGrid dataGrid1 = e.Grid;<br />
int row = e.Row;<br />
<br />
textBox.Text = dataGrid1[e.Row,0].ToString();
this textbox stands on the same form so i could test it and see it quick if it works or not..
but it doesn't...

Quick'n dirty...
In the main form, when a row in the datagrid is double clicked:
<br />
private void dgInfo_DoubleClick(object sender, System.EventArgs e)<br />
{ <br />
Form2 frm=new Form2(ds, dgInfo.CurrentRowIndex);<br />
frm.ShowDialog();<br />
}<br />
In the constructor of Form2:
<br />
public Form2(DataSet ds, int index):this()<br />
{<br />
textBox1.Text=ds.Tables[0].Rows[index][0].ToString();<br />
textBox2.Text=ds.Tables[0].Rows[index][1].ToString();<br />
textBox3.Text=ds.Tables[0].Rows[index][2].ToString();<br />
}<br />
Helpful perhaps...

eh first of all the datagrid is on my form.
the and filled with data from my database.
my data set named "barry11"
which is the correct code to select a row from this grid.
second.
which code do i need te read the first field (firsname) into a textbox on the same form.
if that works i'm already pretty happy. to..
i was thinking.
can't I put the selectet row into a parameter and give this one to my second form. where my select query will be "SELECT * FROM BARRY WHERE FIRSTNAME == PARAM1:" Or something like that. just a theorie that i was thinking of.

First, find the index of the selected row in the datagrid by means of dataGridName.CurrentRowIndex. This rowindex corresponds to the index of the underlying dataset.

textBox2.Text=ds.Tables[0].Rows[index]["firstname"].ToString();
Work with the underlying dataset (ds above) instead of the datagrid.

-----------------------------------------------------------------------
public virtual void customHandler_CustomRow(object sender, CustomRowEventArgs e)<br />
{<br />
Barry1 DSet = e.DSet;<br />
DataGrid dataGrid = e.Grid;<br />
int row = e.Row;<br />
<br />
textBox2.Text=barry11.Tables[0].Rows [row]["firstname"].ToString();
-------------------------------------------------------------------------------
public void dataGrid_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)<br />
{<br />
if (CustomRow != null)<br />
{<br />
CustomRow(this, new CustomRowEventArgs(barry11,dataGrid,dataGrid.CurrentRowIndex));<br />
}<br />
<br />
}
-------------------------------------------------------------------------------
public class CustomRowEventArgs : EventArgs<br />
{<br />
<br />
Barry1 dataSet;<br />
DataGrid grid;<br />
int row;<br />
<br />
public CustomRowEventArgs(Barry1 DSet,DataGrid Grid,int Row)<br />
{<br />
dataSet = DSet;<br />
grid = Grid;<br />

It referred to my previous example.
But I got your code executing on my computer 
I don't know if you forgot to provide all of your code. But I added a delegate to support the event:
public delegate void CustomRowHandler(object sender, CustomRowEventArgs e);
But more important, I also added the following code snippet to the constructor of the class. In my case, in the constructor of the main form class.
CustomRow+=new CustomRowHandler(customHandler_CustomRow);
You have to associate the delegate to the event.
Then it worked, and the textbox was filled with data.

|

|

i assume you mean here:
InitializeComponent();<br />
barryOracleDataAdapter1.Fill(barry11.Barry);<br />
CustomRow+=new CustomRowHandler(customHandler_CustomRow);<br />
<br />
that doesn't work  .
the public delegate void was already in my code i forgot to send it along.
