You mean "minimized"? I wouldn't recommend that, as a minimized form should not be displaying stuff.
You might want to set the parent of the sub-form though;
fo.ShowDialog(this);

Quote: are you missing a using directive or an assembly reference?
Add the assembly (dll) where UserInfoaa is defined.
Make sure that that assembly does not have a "zone identifier" with the value of "Internet" (on the level of the NTFS file system).

Hi ALL !
I want to execute this by OledbDataReader when I want to take ... :
string CalcQuery = @"SELECT SUM(BuyAmount) From SubTblMetal WHERE IDMetal=" + int.Parse(txtId.ToString());
OleDbCommand cmdCacl;
cnnCalc.Open();
cmdCacl = new OleDbCommand(CalcQuery, cnnCalc);
OleDbDataReader dr;
dr = cmdCacl.ExecuteReader();
if (dr.HasRows==false)
{
txtBuyAmount.Text = "0";
throw new Exception();
}
else if (dr.Read())
{
txtBuyAmount.Text = dr[0].ToString();
}
But when my DataReader has not any row ,I have an error for the value of txtBuAmount.Text
please Help , how can get the value of Zero (0) , when dataRow has not any row(value).
Thanks a lot !
|
|
|
|
|
First off, please use a parameterized query rather than concatenating the value into the statement.
Next, don't trust HasRows.
Also, why is that throw in there?
As you are expecting at most one value, you might do better with ExecuteScalar and then test for DBNull.Value (for when ther are no matching records).
You'll never get very far if all you do is follow instructions.
|
|
|
|
|
Very nicely explained 
If You Never Try You’ll Never Know
|
|
|
|
|
I want To do This :
BuyAmount.Text = "0";
When there is No Row in dataReader
thanks
|
|
|
|
|
I understand, but are there ever no rows? Or do you get a NULL (DBNull.Value) when there are no matching rows?
Even if you do get no rows, it's better to handle that with an else on the other if. You don't need two ifs; you don't need to test HasRows.
HasRows is not a member of the IDataReader[^] interface so you can't count on it being in every database system you use (if you ever have to use multiple database system, like I do). Every time I've tried to use HasRows I got burnt.
You'll never get very far if all you do is follow instructions.

Yes , thanks , I use If and else when dbIsNull . It works .

Hello everybody!
At first, I was making a mood(emotion) detection desktop app in real time from a web camera using Human Emotion Detection from Image[^] as reference, but unfortunately, I failed at this. 
Then , I tried something else  ; I searched for a pre-made mood detection in real time app to integrate it as out-tool program. So, I found at http://www.ginktage.com/2011/08/using-face-api-in-c/[^] that there was an API web site called www.face.com which provided what I wanted and a library for c#  . But again, unfortunately, it doesn't exist anymore. 
So, my question is:
Do you know something similar to www.face.com for mood detection in real time , which can be used in c# and can you give examples how to use it in c#?  Or at least, a c# open source program for mood detection in real time? 
Thank you in advance for your help!

I´ve set up business logic handling a connection of a clientsoftware to a serversoftware.
That BL is encapsulated in this interface:
public interface IServerConnectionLogic
{
IObservable<bool> Connected { get; }
Task Connect();
...
}
Connect());
In my viewmodel (based on ReactiveObject) I create my commands, that should trigger the server-connection:
CmdConnectToService = new ReactiveCommand(ServerConnectionLogic.Connected.Select(connected => !connected));
CmdConnectToService.Subscribe(_ => ServerConnectionLogic.Connect());
The command is bound to a button in my UI-XAML.
When pressing the button the subscribed lamda is hit and the "Connect" method is called.
Inside the Observable "Connected" is set to "true.
Also the lambda in the "CanExecute"-parameter of the constructor of the ReactiveCommand is hit.
But the UI is not updated. I would have expected the button to get disabled, sinde the observable "Connected" turns to "true" and the "Select" statement inverts my boolean value...
I´ve tried that with the "RibbonButton" from the WpfToolkit as well as with a "normal" Button. Both are not getting updated.
The same IObservable<bool> is also bound to a member field:
m_ServerConnected = new ObservableAsPropertyHelper<bool>(ServerConnectionLogic.Connected, _ => raisePropertyChanged("ServerConnected"));
while "m_ServerConnected" is bound to a CheckBox (for testing) via a property. That one is working fine, so the observable must be working...
Does anyone have an idea what could be my issue?

public class Sample{
BindingList<something> Some;
public Sample(ref BindingList<something> some)
{
Some = some;
}
}
That class should be keep alive until the application will be closed "hmm that was a bad practice!" but i need it because it will monitor the db if there is a changes in data.
then i have this:
public static Sample s = new Sample(ref SomeVariable)
Now when i passes the SomeVariable with data it is working fine, any changes of the variable "Some" of the Sample class it is reflected to the SomeVariable.
Now the problem rise if the SomeVariable has a 0(zero) items on it and passed to constructor (SomeVariable here is properly initiated), then if the Sample class found changes in the db the SomeVariable is not updated.
I will appreciate for any help will come.
Thank you,
Gilbert

Sorry?
That is a little confused to me - remember that we can't see your screen, access your HDD, or read your mind.
If you want a class instance that exists until the application is closed, then that won't necessarily do it: you want to use a static class, because your existing example can still be Disposed by the GC if there are no references to it. Or just declare an instance in your main form.
Other than that, I can;t work out what you are saying...

foreach (var ri in referencedItem)

}
then create a static object of it
internal class Synchronizers
{
public static SynchronizePersonClass PersonClassSynchronizer;
}
the initializing the bindinglist
ProcessClass<PersonsClass>.PopulateCollection(ref ClassCollections.PersonClassColletction, query);
then initial the static synchronizer with the bindinglist from above
Synchronizers.PersonClassSynchronizer = new SynchronizePersonClass(ref ClassCollections.PersonClassColletction);
Synchronizers.PersonClassSynchronizer.IterationBeforeSleep = 15;
Synchronizers.PersonClassSynchronizer.MaxSleepTime = 10000;
now my big problem that i dont understand is if the ClassCollections.PersonClassCollection has no items on it, then if the synchronizer found new record it doesnt update the ClassCollection.PersonClass then i tried to debug it, the varible "referencedItem" has some items.
but if the classCollection.PersonClass has an item even just 1 before it was passed to the synchronizer there is no problem about it, any moodification in referencedItem will be reflected to ClassCollection.PersonClass and vice versa.
What your thought about that.
Sorry for my bad english and long post.
Thank you
Gilbert

I don't understand what you're actually asking, but I suspect you don't fully understand what ref does, because the way you used it it's not doing anything.
Parameters passed with ref let the called function modify the variable which was passed by ref. For example:
static void modify(ref int x)
{
x += 10;
}
static void main()
{
int y = 5;
modify(ref y);
Console.WriteLine(y);
}
Since BindingList is a reference type, Some will refer to the same object as was passed in anyway, regardless of ref. And if it had been a value type (which it isn't, but if) then the assignment from some to Some would have copied it anyway. Reference types and value types are something completely separate from and orthogonal to ref.
