How do you add an IMAGE proerty to a control that does not have this property?

I think it would be best to tell us what you are trying to achieve. Just adding an image property to a control won't really achieve all that much.

This is the code section

private void OpenImage()
{
try
{
this.openFileDialog1.ShowDialog();
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";

string path = this.openFileDialog1.FileName;
this.viewer1.Image = Image.FromFile(path);
}
catch
{
MessageBox.Show ("Invalid selection. Must be an image file", "Picture Viewer", MessageBoxButtons.OKCancel, MessageBoxIcon.Asterisk);
}
}

This will do it, but if you want the image to actually be drawn on your control you'll have alot more work to do.

using System.Windows.Forms;
using System.Drawing;

namespace MyControls
{
    public class ImageTextBox : TextBox
    {
        private Image image;
        public Image Image
        {
            get { return image; }
            set
            {
                image = value;
                //Do other stuff here
            }
        }
    }
}

Thanks I'll give it a try.

Well, definately not by posting 3 times in under an hour. I'd use the magic google machine to get my answers, but that's just me.

Hi,
I am assigning a generic colection to a datagridview.
I would like to change the positions of the columns in the datagridview control.
Do I do this in the control itself (If so, how) or do I change the column positions in the generic collection (If so, how)

Thanks

Is there a question in there somewhere? Be more specific. What exactly do you require assitance with?

The are no mind readers here, we can't tell what you did wrong (other than this post) unless you include some code, or a better description of what you have done.

Hi I am passing parameters to my console Application via Command Line
ex: MyApp.exe Path="C:\this.txt" Name=1
Now this works ok.
But Is it possible to send Parameters like
ex: MyApp.exe Path="C:\Folder (Test)\this.txt" Name=1

Thanks in Advance

All need is MyApp.exe "C:\Folder (Test)\this.txt" 1
The delimiter for arguments is the space, as long as the path is enclosed in quotes you should be fine.

Hello

After many tries it seemt to me that there is NO safe way to programaticaly make change to a datagridview binded to a datatable in order to get those changes by the getchange method before updating database.

If data are entered manualy by the user : no problem
But if they are changed programaticaly, it seems that the changes are reflected at random :sometime yes, sometime no

The ONLY safe way I found is to use the DataBoundItem of the row in the DGV to acceed the row in the datatable and directly make changes in the datatable

Does anyone had such experience ?

Here is a step-by-step process for populating a datagridview and updating the database afterwards.
Found it in Google in 2 seconds flat. Try searching for you answer first.
Tutorials on using ADODOTNET[^]

I'm sorry

But you probably search to fast and answer too fast without a good understanding of the problem

The article describe how to populate a DS from a connection, close the connection, work with data and then send back to DB (a described)

This is NOT my problem

My problem is that it seems that when DataGridView is using a datasource and you makes change Programaticaly to the DGv, those changes are not always reflected to the Binded dataset.
To turn around that, I'm directly working to the dataset using the DGV as an index but it sounds a little odd to me

Hey guys

i need my MainForm(mdi parent) to trigger an event that ALL the open child forms can handle separately.

Hello Harvey!

My basic concept would be:
1) Creating an event in your ParentForm, which should be handled from the Child Forms

[CategoryAttribute("Harveys Events")]
[DescriptionAttribute("Happens when I want it!")]		
public event EventHandler HarveysParentEvent;

2)Creating an Basis MDIChild Form where all the ChildForms of your ParentForm inherit from!
//Basis Child

public class MDIBaseChild : System.Windows.Forms.Form

//Inherited Child

public class MDIChild1 : MDIBaseChild

3)This Base Form overrides the OnParentChanged as following and handles the "HarveysParentEvent" there!

private MDIParent mdiParent=null; //holds the reference to the parent form
 
protected override void OnParentChanged(EventArgs e)
{
    //MDIChild is added to the MDIParent
    if(Parent!=null)
    {
        if(mdiParent==null)
        {
            if(Parent is MdiClient)
            {
                mdiParent = Parent.TopLevelControl as MDIParent;
                if(mdiParent!=null)
                {
                    //Handles the event
                    mdiParent.HarveysParentEvent+=new EventHandler(mdiParent_HarveysParentEvent);
                }
            }
        }
    }
    //MDIChild has Closed and/or was removed from MDIParent
    else
    {
        if(mdiParent!=null)
        {
            //clears the reference to the parent Form
            mdiParent.Activated-=new EventHandler(mdiParent_HarveysParentEvent);
            mdiParent.HarveysParentEvent-=new EventHandler(mdiParent_HarveysParentEvent); //Edited
            mdiParent = null;
        }
    }
 
    base.OnParentChanged (e);
}

4) The "mdiParent_HarveysParentEvent" is declared as "protected virtual" and can now be overriden from the inherited Child Forms.

//Base Child code
protected virtual void mdiParent_HarveysParentEvent(object sender, EventArgs e)
{
}
 
//Inherited Child code
protected override void mdiParent_HarveysParentEvent(object sender, EventArgs e)
{
    //Implement your code here
 
    base.mdiParent_HarveysParentEvent(sender, e);
}

Hope it helps!

All the best,

Martin
