Either one will work. The point is to have the application wait for input before continuing.

I have a single-form application which I would like to call this.Close() when it ceases to be the active window of the OS. How do I do this?

Use the form's Deactivate event possibly

Add a handler for the Form.Deactivate event. Call Close() in the body of the event handler.
|
|
|
|
|

Do you want to close the app, or hide the window?
Either way, handle the LostFocus event for the form, and do what you want there. Calling Close() in that handler will close the application.

I have made a custom date control using button and text box. Every thing works fine. What i need to know is when the control is placed on a form of smaller size and we click on the button in runtime the control goes behind. but in case of windows datepicker in such situtation the control comes ahead of form. How can we achieve this.

I do not know entierly sure what you mean. Maybe a screenshot would help. I am only guesing.
Such as ComboBox and DateTimePicker. Items shoud be painted on Primary (Non-Client area or Desktop) Display. If you use normaly GDI and draw on client size, and the form is not big enough, then popup wouldn't be painted entirely or a other controls could come on top of other

Not the entire control - at least not if it's partially hidden by a textbox. You're referring to that hovering thing below the date-line? I think that's a window, created in a similar fashion as the tooltip-window.
You might be able to reproduce this by using a ComboBox. It also flaps out a small window

Without seeing your code, it is difficult to tell.
Best guess is that you are storing the date as a string, the format of which is local to your region and / or culture. SQL databases use an internal format of "YYYY-MM-DD" and are culture invariant.
Do not keep your date as a string - store it in a DateTime and pass that to the SQL directly. Convert it to a display string as late as possible, and convert from a string as soon as possible. Not only is it more efficient in terms of space, but you can easitly perform operations such as comparisons, additions, etc. which you cannot with a string.

Hi,
your question isn't particularly clear, however this[^] might be useful.
|
|
|
|
|
I'm not exactly sure what you mean. Do you want to store the Date in a specific manner? If that's the case then check if SQL supports your date format. If not make a function that creates the date in the specified format.
Or you could create a DateToString() method or the other way around.
Any way you could use: dt = DateTime.Parse() and then
check the month,year and day.
Again I'm not sure what you want.

Hi fellow developers.
I come with 2 questions today around the area of serialization. I would normally try these things out myself, but I am away from my development machine today and I was wondering you if you could provide some assistance.
If you added a new property to an existing class that your web service serializes and returns to clients, would it break for existing clients?
If you changed the data type of an existing property of an existing class that your web service serialises and sends to clients, would it break for existing clients?
Many thanks,
TF

Hi,
Adding a new property would normally not break existing clients. Since this is a web service and the client might consume the soap-formatted XML responses in any way there is no guarantee. For example, a client *could* have been implemented in such a way that it assumes the fifth childnode of some element to be "dateOfBirth" and parse it's text as a date, and this would obviously fail if the message format changed so that dob no longer was the fifth childnode. However, part of the point of using XML is of course to enable to use the node names instead, so picking nodes by index is bad practice.
Changing the type of an existing property is much more likely to break existing clients, though it need not always happen. Again things are fuzzy since a client could be implemented in any of a number of technologies, and with any number of tools. Changing from "int" to "byte" might be safe, but might not. I don't know the type definitions in W3C's standards, but generally the only safe changes you can make (that cannot break properly implemented clients) would be thos that result in the property still mapping to the same type in the SOAP message.
You might be thinking of only a subset of the possible clients though, such as .NET clients generated with Visual Studio. Even then there are a few varieties; at least two: WCF clients configured to connect to a web service endpoint, and "pure" web service clients. Adding a property to a class won't affect such clients. Changing the type will also be fine as long as the values actually returned from the service are valid for the old type. Changing from Int32 to byte for example breaks nothing (but also doesn't achieve much), while changing from int to double works (but is pointless) only so long as the values returned fit in an int.

I am working with a DataGridView and I am subscribing to DataGridView.Scroll events. As soon as I get a scroll-event, I query the new cell display area:
private void dataGridView1_Scroll(Object sender, ScrollEventArgs e)
{
Rectangle r1 = dataGridView1.GetCellDisplayRectangle(0, -1, true);
Console.WriteLine("New cell position after scrolling: " + r1.X + ", " + r1.Y);
}
However, it seems the CellDisplayRectangle isn't updated by the time I get the scroll-event. What event should I subscribe to instead to get the correct CellDisplayRectangle after the DataGridView was scrolled?
|

|
|

I would put a boolean value to true, and handle event: RowPostPaint. This event occours after DataGridViewRow finish painting. And there it would check for that boolean property and execute.
private void dataGridView1_Scroll(Object sender, ScrollEventArgs e)
{
scrolled = true
}
private voud dataGridView1_RowPostPaint(Object sender, DataGridViewRowPostPaintEventArgs e)
{
if (scrolled)
{
Rectangle r1 = dataGridView1.GetCellDisplayRectangle(0, -1, true);
Console.WriteLine("New cell position after scrolling: " + r1.X + ", " + r1.Y);
scrolled = false:
}
}

Hi all,
I want to resize my string, getting rid of the last 5 chars.
for example:
after I do this:
string a= "example string 4444";
SomeMethod(a);
I want 'a' to become "example string" and " 4444" chars will be lost.
Is there a built-in function for such thing or should I create a simple algorithm?
Thanks...

Something like SubString?
|
|
|
|

I knew there was sth like this, I remember it from C times.
All I've got to do is to assign the "string size - 5" for starting pos.
thanks for reminding

string a= "example string 4444";
int numToRemove = 5;
a = a.Remove(a.Length - numToRemove - 1, numToRemove);

Hi,
use the substring function.
eg. a.SubString(0,14);
