I dont know what to do, im new to whole coding and the project im working on is going quite well, tried adding more commands and this problem jumps to the first private part here. If needed i can send the rest of the code
RegisterYNCommand();
{
}
private void RegisterYNCommand();
{
{
Commands.CreateCommand("YN")
.Do(async (e) =>
{
int yesnoIndex = rand.Next(randomTexts.Length);
string memeToPost = yesno[yesnoIndex];
await e.Channel.SendMessage(memeToPost);
});
Remove the first
RegisterNYCommand();
{
}
Looks like duplicated code...
and the ; at the end of
private void RegisterNYCommand(); // This ';'
{
Commands.CreateCommand("YN")
.Do(async (e) =>
{
int yesnoIndex = rand.Next(randomTexts.Length);
string memeToPost = yesno[yesnoIndex];
await e.Channel.SendMessage(memeToPost);
});
}
Just remove ; character after your methods declaration:
private void RegisterYNCommand()
{

I have this code:
<div class="col-lg-12 control-section toast-default-section">
<SfToast ID="toast_default" #ref="ToastObj" Title="Error" Content="#a" </SfToast>
</div>
#code{
a = "Test";
StringBuilder b = new StringBuilder();
b.Append("Hello ");
if (b.ToString() != "")
{
a = a+ b;
StateHasChanged();
await ToastObj.ShowAsync();
}
}
When this "ToastObj" open, I need click 2 times to refresh. I don't know why.
For example:
First Result: Test
Second Result: Test Hello
I need click two times to refresh.
For the future, it would be helpful to see all the code, including the SFToast component.
However, You are calling it correctly. All you have to do to Get the page to refresh is to have the code hit the "StateHasChanged()" function. I think the problem is that you have code sitting outside of any function. Consider the #code{} to act like a normal class file with a few diffrences. For example there is no "Constructor" but the first method called on creation will be the OnInitalized(). I suggest wrapping the code and making sure all variables are initialized
#code{
protected override void OnInitialized()
{
var a = "Test";
StringBuilder b = new StringBuilder();
b.Append("Hello ");
if (b.ToString() != "")
{
a = a+ b;
StateHasChanged();
await ToastObj.ShowAsync();
}
}
}
Try use InvokeAsync(StateHasChanged);

I need equivalent for Application.OpenForms[0].InvokeRequired in WinForms for wpf.I tried with
var dispatcher = myDispatcherObject.Dispatcher;
if (dispatcher.CheckAccess()) { /* ... */ }
but no luck
Try the following extension method:
public static void TryToExecuteOnUI(this Action uiAction)
{
var uiDispatcher = System.Windows.Threading.Dispatcher.CurrentDispatcher;
if (uiDispatcher.CheckAccess() == false)
{
uiDispatcher.Invoke(uiAction);
return;
}
uiAction();
}

I've spent the better part of an hour reading over linked items on Google about this topic; however, maybe it just is not sinking in. What do I need to do to capture the return value from a helper class in C#? This is the code:
protected void Page_Load(object sender, EventArgs e)
{
HelperClass.Calculate(a, b);
}
public static string Calculate(string a, string b)
{
string value = string.Empty;
// inner code workings
return value;
}
I know I'm missing something but I cannot for the life of me determine what. Any help would be appreciated! Thank you!
var x = HelperClass.Calculate(a, b);
Just like any other function, which returns a value?
protected void Page_Load(object sender, EventArgs e)
{
string value = HelperClass.Calculate(a, b);
}
public static string Calculate(string a, string b)
{
string value = string.Empty;
// inner code workings
return value;
}

I get this error for the code shown below and don't know why.
my code is:
protected override void OnStart()
{
if (WCHSBMobileApplication.Current.SuperBillObject == null)
{
AddSuperBill();
}
else
{
EditSuperBill();
}
}
what can I do?
The exception message says it all:
You removed this line:
base.OnStart();
You need to add it back:
protected override void OnStart()
{
base.OnStart();
if (WCHSBMobileApplication.Current.SuperBillObject == null)
{
AddSuperBill();
}
else
{
EditSuperBill();
}
}

I'm a novice programmer, so forgive me if this is something obvious. I've checked all the braces and find matching pairs in all cases here. The code compiles fine without this snippet. Any ideas?
protected bool Bullish(int ConsecutiveBullishBars)
{
private int howmanybars = ConsecutiveBullishBars - 1;
private bool IsMarketBullish = false;
while (howmanybars >= 0)
{
if (Close[howmanybars] > KeltnerChannel(Offset, Period)[howmanybars])
{
IsMarketBullish = true;
}
else
{
IsMarketBullish = false;
}
howmanybars--;
}
return IsMarketBullish;
}
Here is the full code: http://pastebin.com/aHbzqKbw
It doesn't make any sense to mark local method variables as private. That is what is causing your errors.
Why the compiler is giving you an } expected error, I'm not sure. I'm guessing that the compiler is assuming that private int howmanybars is being interpreted as a private instance field definition, which cannot be declared inside a method. So it is telling you that it expects the Bullish method to end before the declaration.
protected bool Bullish(int ConsecutiveBullishBars)
{
int howmanybars = ConsecutiveBullishBars - 1;
bool IsMarketBullish = false;
while (howmanybars >= 0)
{
if (Close[howmanybars] > KeltnerChannel(Offset, Period)[howmanybars])
{
IsMarketBullish = true;
}
else
{
IsMarketBullish = false;
}
howmanybars--;
}
return IsMarketBullish;
}
