Hello Vinay,
Thanks, it solved my purpose. Can we configure some other items (other than those provided in the dropdown)to this status strip in runtime?
Regars,

One of my articles might be able to help you their: Custom ToolStrip Renderers[^]. You are able to add other controls using the ToolStripControlHost. You can browse most of the classes that can manipulate the ToolStrips by using the Object Browser.

I am trying to add propertyitem dynamically to property grid.
For example If I want to add a property Item Like a text box which takes "String name" as variable how to add dynamically to property Grid?
I can do the following to add the "name" text box at static design time:
public class PropertyGridProcessDesigner
{
[Editor(typeof(PropertyGridProcessDesigner), typeof(System.Drawing.Design.UITypeEditor))]
public string Name
{
get { return name; }
set { name= value; }
}
}
But how to achieve the same above thing at run time ?
Do we need to create dynamic classes to add Property Item ?
If so, can anyone please share any information you have ?
Thanks,
rajan

// Save the stream to disk
System.IO.FileStream newFile = new System.IO.FileStream(Server.MapPath(sSavePath + sFilename), System.IO.FileMode.Create);
newFile.Write(myData, 0, myData.Length);
newFile.Close();
TextWriter tw = new StreamWriter(Server.MapPath("Images/Saved Images/info.txt"));
// write a line of text to the files
tw.WriteLine(txtFName.Text + " " + txtLName.Text + " " + IDTextBox.Text + " " + sSavePath + sFilename);
// close the stream
tw.Close();
it works but whenever i try to upload 2 or more files/images... it will just overwrite the exisiting texts.. how do i make it such that it will create a new line each time i upload an image upon the existing ones?

Do you mean you want to open an existing file and APPEND data to the end of it?

This creates a new file, like it says. Use Append to add to an existing file.

Hi,
File.AppendText() seems to be the easiest way to get what you want.

Hi all,
Basically i have 2 question in this message.I am using DataGridViewComboBoxColumn to insert a ComboBox into my datagridview.Code as below:
dataGridView1.Columns.Remove("Seqence_Number"); <----remove the original column first before add the combo box
DataGridViewComboBoxColumn dgvComboBox = new DataGridViewComboBoxColumn();
dgvComboBox.DataPropertyName = "Seqence_Number";
dgvComboBox.HeaderText = "Sequence (Stage)";
dgvComboBox.DropDownWidth = 100;
dgvComboBox.Width = 100;
dgvComboBox.MaxDropDownItems = 10;
dgvComboBox.FlatStyle = FlatStyle.System;
dsTemp = singleton.ProdetailsDataset.Copy(); <-----dataset will copy from my singleton class
dgvComboBox.DataSource = dsTemp.Tables[0];
dgvComboBox.ValueMember = "Stage_Name";
dgvComboBox.DisplayMember = "Stage_Name";
dataGridView1.Columns.Insert(1,dgvComboBox);
The first question is, how can i display more than one value member in ComboBox?
The second qeustion is, how can i do a selected event for that ComboBox in datagridview? what i wanna do is when user select the value in ComboBox, some event will fire to validate the value which selected by user.
Any tips are welcome,
Thanks in advance

Hi,
1) Concatnate the two column values (in a query) and assign as a value member.
2) You can use "EditingControlShowing" event to access the "SelectedIndexChanged" event for combobox cell.
Here is the Code Snipet:
private void Form1_Load(object sender, EventArgs e)
{
this.dataGridView1.EditingControlShowing += new System.Windows.Forms.DataGridViewEditingControlShowingEventHandler(this.dataGridView1_EditingControlShowing);
}
private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
ComboBox ctl = e.Control as ComboBox;
if(ctl!=null)
ctl.SelectedIndexChanged+=new EventHandler(ctl_SelectedIndexChanged);
}
private void ctl_SelectedIndexChanged(object sender, EventArgs args)
{
MessageBox.Show("Selected Index Changed Event");
}
Thanks,
Gopal.S

Hi Gopal.S
Thanks for your suggestion. I am just figure out how to do it, but seem you have a better suggestion
1) I just simple Concatnate the columns after i get the dataset, something like below:
string s = dsTemp.Tables[0].Rows[1][2].ToString() + dsTemp.Tables[0].Rows[1][3].ToString();
2) I am using CellEndEdit,as below;
this.dataGridView1.CellEndEdit += new DataGridViewCellEventHandler(dataGridView1_CellEndEdit);
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
string cellvalue;
if (e.ColumnIndex == 1)
{
cellvalue = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();
if (cellvalue != null && cellvalue != "")
{
}
}
I will try you suggestion too, Thanks

Member Function Pointers usage on class instances:
Class A is derived from Class ZZZ. Class A has a member function A::ftnOnA
Class B is derived from Class YYY.
Class A instantiates Class B
Could Class A pass a member function pointer to Class B and then Class B be able to call A::ftnOnA? (Like a call back procedure)
Can anyone please help me?

You can set up a delegate to achieve this.

Hello all! I have a college project due tomorrow and I am in dire need of some assistance! The project requires that I create a plain windows form with six controls on it; I have chosen six buttons. Form2 will be the startup form, will have a combobox and a DataGridView (I am using a richTextBox right now, but will change that once the rest works). The names of the controls from Form1 populate the combobox in Form2. By selecting one of the controls from the combobox, all of that controls' properties are then listed in the DataGridView.
I have most of it working, but I cannot get the value for each property using the GetValue(object, object[] index) method. I have tried all that I can think of, but cannot get it to work.   The code that I have for Form2 is as follows:
Here, the main problem is on the bottom line of code. I have commented there.
public partial class Form2 : Form
{
//Declares an Array of type Controls:
Control[] controls;
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
//Creates an instance of Form1:
Form1 myForm = new Form1();
//Initializes the Control[] by calling the getControls() method on Form1:
controls = myForm.getControls();
//Adds the Control names to the ComboBox:
foreach (Control c in controls)
{
myCboBox.Items.Add(c.Name);
}
}
private void myCboBox_SelectedIndexChanged(object sender, EventArgs e)
{
//creates an int to hold the selected index:
int index = myCboBox.SelectedIndex;
//creates a type variable:
Type t = controls[index].GetType();
//clears any previous entries:
richTextBox1.Clear();
foreach (PropertyInfo prop in t.GetProperties())
{
//Here, the GetValue method will not work! I have tried passing everything that I can think of to it
//and still it will not work. It keeps telling me that target object does not match.
//Please help.
richTextBox1.Text += "\n" +
prop.Name + "\t\t:" + prop.GetValue(t, null);
}
}
}

Perhaps the first form should have a public property that yields a list of the names of the controls?
|
|
|
|
|
The first form does. It has an array of Controls that are populated by the Controls that are on it. There is a method, GetControls() that returns the array of Controls. Form2 then loops through that array and populates the comboboxlike so:
foreach (Control c in controls)
{
comboBox1.Items.Add(c.Name);
}
I know that this is working because when the code is ran, if you take away the faulty attempt to call the GetValue(object, object[] index) method, all of the property names are properly displayed in the richTextBox.
I need to know the proper way to call the GetValue(object, object[] index) method to get the property values, given the way that I am going about the logic.
Thanks.

You are trying to find the property value from the type, you have tried to get it from the object itself
richTextBox1.Text += "\n" +
prop.Name + "\t\t:" + prop.GetValue(controls[index], null);

Hello all,
I am looking for a program that will generate C# classes from a xsd schema.
A. I need it to be able to generate separate .cs files for the schemas that are are imported.
B. I need it to generate partial classes and would like it to generate generic collections.
C. I need it to be a free, downloadable program.
I have looked at the following tools:
1. xsd.exe - Does not generate multiple files.
2. XSDObjectGen - Does generate multiple files (given that the schemas have different namespaces), will generate partial classes, but it uses ArrayLists for it's collections (if it's 2.0 aware, why on earth would it generate ArrayLists?).
3. XSDClassGen - Does generate Generic collections, but does not generate multiple files.
4. CodeXS - Is an internet only tool.
Thanks in advance.

I found another one that doesn't do what I want.
It's called 'Dingo'. The author claimed that it's highly extensible.
When I tried to compile the classes it generated, they didn't compile.
It also doesn't generate partial classes unless you write a plugin for it.

Hello CBadal,
Do you have any luck on generating .cs files for the schemas that are imported.
If so can you please help me how to do.
Please assist me.

I want to build an application in windows forms to run another program which is console base program. how can i open my console program passing parameter to cmd and my console program have also some parameters.

The main method of your application will receive the parameters. You can use the Process object to send and receive commands. Also you can use MSMQ.

Hi,
here are some facts:
1.
every process starts executing some kind of main method or function.
Under .NET the static main() method optionally gets as a parameter a string[] args array
holding the command line parameters.
You can make your app such that it reads that string array, and acts accordingly
(e.g. opens the file or files for which it gets paths).
2.
You can get the same information by using Environment.CommandLine or Environment.GetCommandLineArgs()
3.
You can provide command line arguments in many ways:
- by typing a command in a "DOS Window" (or the "Run" menu under the Start button);
- by having a command line in a batch file (extension .bat) which you execute by double-clicking;
- by adding them to the "Target" field of a desktop shortcut.
4.
Tou can programmatically launch another process and provide a command line while doing so;
it takes the Process class; either use Process.Start method, or instantiate a Process object,
set its StartInfo property, then Start() it.
Have a look at the documentation for all items mentioned!
