I have from in C#, i am creating some panels on it at run time and add some forms into those panels
i need to save form sate in a way so that when i close my form it should save what ever i draw on it. and when re open it ... it should show me last contains which i draw on form..
Help me in this regards
i m really stuck in this issue..

It's really easy. You have to write code to do it. When your form closes, it fires and event. When it opens, it fires an event. Catch both, in one write the values where-ever you like, read them from the other and put them in the form.

What the hell ? What does the singleton pattern have to do with persisting settings ?

Hey, I think i dint got your question properly, can u let me know that, the form which you are closing is Main form of the Application or child form.
If it is main form then you need to capture the "form load" and "form closing" event of the form, and write your own code to save the settings on closing, and load the settings when the form is loaded.

I have some data on Collections model such as projectid, projectType and projectname. I stored this data as collections as below:
Collections<User>Projects = new Collections<User>;
foreach (DataRow dr in ds.Tables[0].Rows)
{
User u = new User();
u.ProjectId = Convert.ToInt32(dr["ProjectId"]);
u.ProjectType = Convert.ToString(dr["ProjectType"]);
u.ProjectName = Convert.ToString(dr["ProjectName"]);
Projects.Add(u);
}
This is working fine and I am able to insert data in this. Now I want to bind this collections to a RadioButtonList. means I need to show only the ProjectName for the RadioButtonList. So how will I bind this Collections<user> to a RadioButtonList? Can anybody please help me on this? Thanks in advance.
Thanks,

Hi,
I needed to find the path of the MSI file through which i am installing the s/w.I needed to check certain file's path during installation(when Installer class is called ...
How can i get the path of the msi file from where the Installation initiated?.
Please Help...
|
|
|
|
|
Get it from where ? Within the MSI ? You can;t write MSIs in C#, can you ?
What I tend to do, is write my install path in the registry, so that other apps can find it later if need be, such as patches.

I think U didn't get me..
I just wanted to know a whether flie (like name 'abc')is in the same folder/path from where my installation package executed. I am using custom installation during which at a time i needed to look for this file if exist ignore else create..
I wanted to add this check when i call Install method..
|

What install method ? You say you're calling an install method, but you're talking about MSIs in a C# forum. So, are you using C# to write an MSI ? Are you calling some other sort of method, called install, that runs an MSI ? Are you talking about a C# program, or a process within the MSI ?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.IO;
using System.Reflection;
namespace Trade.CustomInstallation
{
[RunInstaller(true)]
public partial class CustomInstallation : Installer
{
public CustomInstallation()
{
InitializeComponent();
}
public override void Install(System.Collections.IDictionary stateSaver)
{
"Here I need to Check for the File "
ConfigurationForm frmConfig = new ConfigurationForm();
frmConfig.ShowDialog();
base.Install(stateSaver);
}
protected override void OnAfterUninstall(System.Collections.IDictionary savedState)
{
base.OnAfterUninstall(savedState);
//This method is used to delete all the files after uninstallation.
string rootPath = string.Empty;
string clientPath = string.Empty;
DirectoryInfo directoryInfo = Directory.GetParent(Assembly.GetExecutingAssembly().Location);
string currentDirectory = directoryInfo.ToString();
char[] separator = { '\\' };
string[] pathArray = currentDirectory.Split(separator);
//condition for Single drive like c:\
if (pathArray.Length == 2 && string.IsNullOrEmpty(pathArray[1]))
{
rootPath = currentDirectory + "Root";
clientPath = currentDirectory + "Client";
}
else
{
rootPath = currentDirectory + @"\Root";
clientPath = currentDirectory + @"\Client";
}
string[] subDirectories = Directory.GetDirectories(currentDirectory);
for (int subDirectoryCount = 0; subDirectoryCount < subDirectories.Length; subDirectoryCount++)
{
//Delete Root Folder
if (rootPath.Equals(subDirectories[subDirectoryCount]))
Directory.Delete(rootPath, true);
//Delete Client Folder
if (clientPath.Equals(subDirectories[subDirectoryCount]))
Directory.Delete(clientPath, true);
}
}
}
}

I didn't know you could write an msi in C#. So, all you need is System.IO.File.Exists to see if a file exists already ?

Hi,Friends i developed one application in C# win appl.
I used Globalization that i want to display all my lables,txtbox values,tabs in kannada.
but it working to labels that i am reading from resx.file.
But i am not getting to tabs,also store my txtbox values in access.
I am using Kannada Direct,MS access,  problem is values in txtbox showing boxes.but it
storing kannada values in access.while retreving also it showing boxes.
please Help to come out.

I can vaguely understand this, but not well enough to know what you're asking....
What is Kannada Direct ?
Yathish hatter wrote: problem is values in txtbox showing boxe
Oh, OK. I think the problem is that the textbox is not using a font that includes the characters that are stored. So, you need to set the font of the textbox to one that can display those values.

Hi
I am displaying a collection of objects in a datagridview by setting the datagridview's datasource to the collection property.
It works well, but now i want to display one of the properties as a combobox and not as a text field. I have found examples where one manually adds a new column and then setting it as a combobox, but nothing where the columns are automatically set from the properties of the object. Hope i make sense.
|

you have to manually add the ComboBox column.
try this
DataGridViewComboBoxColumn DGVcombo = new DataGridViewComboBoxColumn();
DGVcombo.HeaderText = "Combo Column";
DGVcombo.Name = "AnyName";
dataGridView.Columns.Add(DGVcombo);
