i want to save a DataTable in Properties.Settings. All just works fine untill i restart the app.
here is code on forms Load
if (Properties.Settings.Default.Limits_DT != null)
{
main_DT = Properties.Settings.Default.Limits_DT;
}
else
{
main_DT = new DataTable();
}
and another one is
private void LE_FormClosing(object sender, FormClosingEventArgs e)
{
Properties.Settings.Default.Limits_DT = main_DT;
Properties.Settings.Default.Save();
}
it works but only if application keep running. I dunno why Save() is not working. I use Settings often but this time i need a DT
any idea... ?

Do you really need a datatable, or do you just need the data it contains ? What if you stored the data as XML ?

I'm creating a lot a picture boxes. Each picture box has a constant height and width of 50. So I randomly place this picture boxes on the form. My problem is that some picture boxes overlaps or on top of other picture box. How do I solve this problem?
|
|

|

You need to look at the existing picture boxes and if they overlap with your new picture box then move your new picture box.
Detecting an overlap is fairly simple. Each control can give you its Bounds[^], which is a Rectangle[^] object. The Rectangle structure has an IntersectsWith[^] method which will return true if the rectangles intersect (overlap) with each other.
For example:
bool isOverlapping = firstPictureBox.Bounds.IntersectsWith(secondPictureBox.Bounds);

I've got a VisibleChanged handler in a UserControl class that performs some functionality that includes using "this". When I run the code as an app, it works fine, but when I try to load the UserControl into the designer, the IDE crashes. Is there a way to hide code from the designer, like a convenient compiler directive or anything?

I don't know whether there is a directive or not but you can check whether the control is at design time or not. See here: Detecting Design-time in C#[^]

Neither of the methods there worked for me, but it allowed me to use different search criteria in google, and found an answer right here on CP:

I am glad to here that you found an answer. Thanks for the article link

I see you solved this, let me just add that the designer has become a bad joke, it runs about half of your code, and if that code relies on other code that it doesn't bother to run, it crashes. MS says this is a feature.

The designer is definitely a like bad dream once you start to do anything more complicated than simply accepting the default form in a new WinForms app, but You're forced to use it if you want a reasonable chance at designing a form in a short amount of time. Are there any alternatives that don't include the acronym "WPF"?

Hi,
my question is that how we can put a Hyperlink in the MessageBox in C#.
Thanks,

You can't do it with standard messagebox, you need to develop your own and use linklabel control

Hi friends,
I have created voting application,i have almost finished it but i should check that one user should vote once by getting his session any idea for this....
Checking IP address will prevent other users voting so i need to take user browsers session or some other ideas for this method.....
|

First of all, we have an ASP.NET forum, why did you not ask there ?
Second, there's no way to do this. A new session is created when someone reconnects to your site, and so an IP address is your only option, and that won't work if someone has a dynamic IP and reconnects to the web. The only way for this level of control is to issue people with a login and let every login only work once.

Hi,
I'm currently in the planning stages of a medium sized application.
The essence of this application will be a website, similar to hotel booking sites like booking.com
I'm deciding what data access to use...
I've narrowed it down to two options - nHibernate, or Microsoft Data Access Application Block
In what situation would either of those be a better option?

Hello,
Have you tried using the
ShowDialog() method when you are opening the second window from within the form1's code? E.g.:
private void button1_Clicked(object sender, EventArgs e)
{
Form SecondForm = new SecondForm();
SecondForm.ShowDialog();
}
This will open the second form on-top of the first form, and the main form cannot be accessed until the second form has been disposed.
Hope this helps.
j.t.
