Hi
i think you have done well but you have missed to set autoincrement step in yours code. so add the following line of code just after the line where you have set the autoincrementseed.

dc.AutoIncrementStep = 1;

i htink yours problem will be solved. Smile | :)

have you made autogenerated column property of datagrid false? if you are using all the columns of datasource in datagrid then make it true. in that case you will not need to specify the column name for datagrid. Smile | :)

hi
if you are using all columns of datasource in datagrid then make true autogenerae column property of datagrid and if u still dont get the value then try to get it in debug mode n check that in table you are getting all values or not.
In debug mode you will get the place of error.

I have a windows form with a button that I have set the DialogResult property.

The button also has a click event.

When the click event fires, my event methods displays an MessageBox with Yes or No buttons. (an 'are you sure' type message)

If the user clicks the No button I want to cancel closing of the window form event.

How I can I achieve this.

Thanks

private void button1_Click(object sender, EventArgs e)
{
    DialogResult dr = MessageBox.Show("Are you sure you want to close this window?", "Are you sure?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (dr == DialogResult.Yes)
    {
        this.Close();
    }
    //if anything other than Yes is clicked (like No), then nothing will happen.
}

The problem stems from button1 having it's DialogResult property set.

When button1 click event is fired, it executes button1_Click, displays the are you sure dialog and regardless of the result of the are you sure dialog will close the window form because it has a DialogResult set.

I was wondering if I could cancel this close window event depending on the result of the are you sure dialog.

I can simply not set the DialogResult property of button1, and set the DialogResult in the button1_Click event depending on the result of the are you sure dialog.

Regards.

Why not remove the DialogResult from button1 and assign it to the window only if it is closing:

private void button1_Click(object sender, EventArgs e)
{
    DialogResult dr = MessageBox.Show("Are you sure you want to close this window?", "Are you sure?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (dr == DialogResult.Yes)
    {
        this.DialogResult = DialogResult.Cancel; //or whatever
        this.Close();
    }
    //if anything other than Yes is clicked (like No), then nothing will happen.
}

f(g) is a function with g defined as one parameter delegate function: g(*)

Now we want to calculate f(h(*,1)),f(h(*,2)),f(h(*,3)),f(h(*,4)).....
Is there a way to realize this application efficiently?

If by "graphic", you mean image, then you can just set the BackgroundImage property of your form to the image, or add a PictureBox control to your form and set its Image property to the image.

Set the BackgroundImage property of the form and BorderStyle = FormBorderStyle.None;
Then handle the OnMouseDown, OnMouseMove, and OnMouseUp events to deal with moving the window, closing, maximizing, and minimizing it (and if you want, resizing it).

yes i use this way but, it doesn't work fine.
Becouse when i load the form, i see all the picturebox with images all transparent for a bit, then i see the image.
I want to open the form then see imediatly the image.

Handle the OnPaint event of the form and draw the image there. You may also have to optimize your image so that it can be loaded quickly.

Hi,

Is there any article that explains how to highlight specific words inside a RichTextBox? If not, how shud I do it? Confused | :confused:

There is no patch for ignorance

From Highlight Text in a Rich Text Box[^]:

Text highlighting is part of the Rich Text Format specification, but is mysteriously missing from the Windows Forms Rich Text Box component.

So, you may want to check out Alpha Blended (Transparent Capable) TextBox and RichTextBox[^] from right here on CP.
