Won't work, @ tells the compiler it doesn't need to take in account the escape character. ('\') it is not part of the string itself.
Store the variable as "f:\\pick_up\\" or use @"f:\pick_up\" which is the same. It will be saved as "f:\pick_up\" and when you get it out it will come out as "f:\\pick_up\\" which is what you need.
If it still shouldn't work, post the error message and check the debug information.

thank you so much V,'f:\\pick_up\\' worked.
but not @"f:\pick_up\".y so?
also when i explicitly put d path in d command string[] folderPath = Directory.GetFiles(@"f:/pick_up", "*.jpg", SearchOption.AllDirectories);it works.
but when i retrieve d same string saved in d databse i get d error.
im new to c#.

When you retrieve it from the database, the string contains @. What you are issuing as a command is Directory.GetFiles("@\"f:\pick_up\"", "*.jpg");. That is why I told you to remove the @ earlier. Perhaps you might listen next time.

Don't guess. Paste the entire Exception.ToString here, the error-message will point where the problem is.

Good day
I am using Visual Studio 2010 to develop a Windows app. I am busy with a module where the user can specify setting for days of the week, for example Mondays the lunch duration is 1 hour, Tuesday it is 30 minutes, and so on.
I want to display the days of the week (Sunday, Monday, …) in a ComboBox so that the user can select a day.
The DisplayMember must be the name, e.g Monday
The ValueMember must be the ordinal number of the day in the DayOfWeek enum, e.g. 1
How do I populate the ComboBox using the DayOfWeek enumerator?
I tried:
private void Form1_Load(object sender, EventArgs e)
{
for (int j = 0; j < 7; j++)
{
comboDay.Items.Add((DayOfWeek)j);
}
}
private void comboDay_SelectedIndexChanged(object sender, EventArgs e)
{
MessageBox.Show("Selected Day = " + comboDay.SelectedValue);
}
This shows the DayOfWeek names in the combobox, but the SelectedValue is always null.
Any suggestions on better ways of doing this?
Thanks.

Use SelectedItem instead of SelectedValue.

Thanks
I feel a fool for not thinking of that.

It's always the way. As soon as someone else looks at it, you see it.

public static List LI = new List();
|

Unless you've created your own class called List, you are missing the generics part. You should declare it like this (assuming it's a list of ints for instance):
public static List<int> LI = new List<int>(); A few points:
1. Your question should not be the header. Make it part of the post instead.
2. Calling a list LI isn't a great idea. You should always look to use meaningful names in your code.
3. Use <pre> </pre> around code samples. The code tool in the editor toolbar will help you with this.

PLSSS DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.
And while you are at it, drop the txtspk as well...

When using VKontakte API method wall.get or friends.get client receives a response just once. When increasing for example the offset parameter such requests do not pass. An error is returned InnerException = {"The request was aborted: Could not create SSL / TLS secure channel."}. What is the possible reason?
|

You have posted a fair bit here about this API. I would suggest that you would be better off seeking answers from the support forums at vk.com. You also never seem to show code. Here's a hint, we can't read minds so we don't know what's wrong with your code.

Hi all,
I have some COM components(activex control without wrapper), which are added at runtime. I met with some problem on latebound call to some properties.
for example, a "Picture" property. I can manage to set a stdole.ipicturedisp by this way:
host.GetType().InvokeMember("Picture", BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty, null, host, new object[] { value });
this works witout any problem when value is not null. but when i need to clean the picture by passing value as null, i got a
system.reflection.targetinvocationexception.
everything works if i don't use lateboud, i.e.
host.Picture=null;
any idea on fixing this problem?
thanks in advance..

Try to pass something like IntPtr.Zero in the place where you are passing null.
Basically, if your com object expects a ref type of variable, it will not be able to accept a null.
You could also create a dummy variable, assign it and then pass it to the com method.

I tried IntPtr, but it still not work
object value = IntPtr.Zero;
host.GetType().InvokeMember(_Name, BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty
, null, host, new object[] { value });
System.Reflection.TargetInvocationException
Message=""

I am using the entity framework to retrieve data from a database. I pull a collection of objects and bind them to textboxes. The problem I am having is when I try to edit the textbox that is bound to an integer field. Any changes I make to the textbox are changed back to the original value when the textbox is exited. Anyone have a solution to this, beside changing all my database columns to varchar?
|

You could try to create a custom UserControl that has a TextBox and a bindable property[^] on it to translate the the textbox.Text field into an integer:
[System.ComponentModel.DefaultBindingProperty("NumericText")]
public partial class NumericTextBox : UserControl
{
public NumericTextBox ()
{
InitializeComponent ();
}
public int NumericText
{
get { return Convert.ToInt32(this.textbox1.Text); }
set { this.textbox1.Text = value.ToString(); }
}
}
Jack of all trades ~ Master of none.
