Hello,

Let's say there are one ToolstripStatusLabel and ToolstripProgressbar in Statusbar.. I have set the width of label explicitly. I want to show the progressbar in the rest of area without setting width explicitly..

For example:

[statusbar with Dock=Bottom]
[label width="200"]
[progressbar width="*"]
[/statusbar]

How can I do that?

I'm using VS 2008 for winform..

Thanks and Regards,

Also can I show data from Variables into reports?

how can i read a black pixel in binary image and displays it on a test box??

13-May-08 20:10

You seem to be confused. This forum is not for talking to the people who write the site, but to the whole community. I have a series of articles on image processing, not sure if any of them create fish eye images, although I've written code to unfisheye images before. What did you see and what do you want to do ?

Event firing in selectIndexChanged event

Read my first image processing article for how to do this, it's pretty straightforward. It's here on CP

Hello,

VS 2008.

I have the following code in the SelectedIndexChanged event of a combo box.

 <br />
DataRowView drv;  <br />
                        drv = (DataRowView) this.bsRedialedNumbers.Current;<br />
<br />
                        if (!drv.Row.IsNull("Number"))<br />
                        {<br />
                            phoneNumber = drv["Number"].ToString();<br />
                            name = drv["Name"].ToString();<br />
                        }

I have the combo box and a button. The user will select a name from the comb box and click a button to do something with that name. However, I have noticed that when I click to change an item in the combo box the event will fire once. Which is correct. However, when I click the button, this event will fire twice.

When the event fires for the second time it will give a -1 for the row. Which is not what I expect. As an item has been selected.

To do a quick fix for this problem I check for IsNull on the number column. Which works. However, I would like to find a complete solution for this problem. At the moment I haven't found one.

The reason I think the event fires twice when the button is click, is because the combo box has lost focus. But cannot see why this would fire the combo box. And why it would return a -1 for the row.

Many thanks for any suggestions and help,

Steve

DataGridView and Control Box Closing

13-May-08 19:05

Yes, a lot of events are like this, a radio button's check changed is another - it fires twice because a deselect fires, as a select does. I guess a deselect occurs as part of the sequence, hence the -1.

I have a bound DataGridView on a form with the CausesValidation property set to true (as I want). The CausesValidation property of the form is false. When I click on the Control Box 'x' to close the form, the 'RowValidating' event of the DataGridView fires, and even if I execute a Cancel in that event, the FormClosing event still fires. Ideally I would like to either have the Control Box 'x' not cause the 'RowValidating' event of the DataGridView to fire, or have the Cancel in the 'RowValidating' event prevent 'FormClosing' from firing. Does anyone know if either of my preferred "solutions" is feasible when the DataGridView has its CausesValidation property set to true?

Thank you...

Avoid contextmenustrip pop-up

baranils13-May-08 9:00

13-May-08 9:00

Hello

I want to know if is it possible to avoid the pop-up of a contextmenustrip (below mentionned as ctxs)

Explaination :

In a Picture Box I've defined a ctxs
Mousedown right doesn't display it
Mouseup right display it

I want to avoid the display if during the mouse down the user made a signifiant mouse move

Any idea ?

Hi baranils,

Here is my suggestion(please point out if i misunderstanding your question)..Get the mouse down location and compare the mouse up location, if there are different, don't display the contexmenustrip. Below is sample code:

private int x,y;

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    x =e.X;
    y =e.Y;
}

private void Form1_MouseUp(object sender, MouseEventArgs e)
{
     if (x == e.X && y == e.Y)
     {
        contextMenuStrip1.Show(this, e.X, e.Y);
     }
}

Hope this help Smile | :)

Thank you !

But this is not the solution

My problem is not in the logic to apply
My problem is HOW to control the AUTOMATIC popup of a contextmenustrip !

Hello

If a define a contextmenu strip
I assign it to the control I need (a picture box in this case)

That's all !

After that I normaly have no control on the display
It shows up automaticaly on the MouseUp event

So my question is not how to manage the logic between event but how to avoid the automatic pop-up if needed !

cocoonwls14-May-08 15:09

14-May-08 15:09

hi baranils,

I am not sure that,normally i am using event handler to control pop up contexmenustrip. Or i will add the code like this.contexmenustrip = this.contexmenustrip1 in form.designer (this will automate the pop up of contexmenustrip),Or there have a properties call autoclosed to control pop up.

Sorry that if i cant help you Poke tongue | ;-P

baranils14-May-08 18:59

Hello

FYI

This is the solution

In my form, I declare a bool attribute : DisableCtx;
Set to true or false depending the context
And I use the opening event

ctxmnuPB.Opening += delegate(object sender, CancelEventArgs args)
{
args.Cancel = DisableCtx;
};
