I need help as mentioned in the title.
I have a timer routine that will update the text of a label. It's a decode text effect, but it doesn't seem to update when the timer routine is executed. I am using C#.

int sumOfDigits = charArray.Where((e) => e >= '0' && e <= '9')
.Reverse()

Here you can found the project
Please help me to fix this problem :( thank you.
This is a threading issue, you can only change UI elements on the UI thread and the timer callback _timerAnimate_Tick will execute on a background thread.
You can see this by logging the thread ID for DecodeTextViews constructor and its _timerAnimate_Tick method:
public DecodeTextView(Context c, IAttributeSet args) : base(c, args)
{
// ...
Console.WriteLine ("DecodeTextView executing on thread: " + System.Threading.Thread.CurrentThread.ManagedThreadId);
}
private void _timerAnimate_Tick(object sender, EventArgs e)
{
Console.WriteLine ("_timerAnimate_Tick executing on thread: " + System.Threading.Thread.CurrentThread.ManagedThreadId);
// ...
}
Which will render the following in the log output:
DecodeTextView executing on thread: 1
_timerAnimate_Tick executing on thread: 6
This is simply fixed by changing the Text property of DecodeTextView on the UI thread using the Post method:
private void _timerAnimate_Tick(object sender, EventArgs e)
{
if (_initGenCount != 0) {
Post (() => {
Text = _decodeEffect.GenerateNumberRange (Text.Length);
});
_initGenCount--;
return;
}
var decodeMode = _showing ? DecodeMode.Show : DecodeMode.Hide;
var text = _decodeEffect.Peek (decodeMode);
if (text == null) {
_timerAnimate.Stop ();
} else {
Post (() => {
Text = text;
});
}
}

I am developing a C# Windows Form program in which there are a number of called Methods (what in VB I called Subs). Excuse me if I'm using the wrong terms, new to C#. One of these methods is being ignored, CreateFolder(). When I set break points to debug and step through, the program gets to the called method and goes right through it like it like it was a blank line, no errors warning just goes through. The program is a bit large so I'm including what I hope is helpful. Sorry if too much. The method (sub) not being executed is CreateFolder(). Again, the debugger will stop on this line[CreateFolder()] in the ProcessEmail() routine but just goes on without going to the called code. Thoughts?

Hi I have this two blocks of code
when I navigate the browser to a url and try to wait for it I get a deadlock I think=) any help suggestions are much appreciated!
I'm just adding some more text here so I am able to post the question :/ sorry
foreach (var davaType in davaTypes)
{
Parallel.ForEach(years, year =>
{
ts.Add(Task.Run(() =>
{
var th = new Thread(async () =>
{
await doWorkAsync(year, davaType, tarafType);
Application.Run();
});
th.IsBackground = true;
th.SetApartmentState(ApartmentState.STA);
th.Start();
}));
});
}
and
public static async Task doWorkAsync(int year, string davaType, string tarafType)
{
using (var browser = new MyBrowser())
{
Console.WriteLine("Im Created Here");
browser.Navigate("some url");
while (!browser.MyLoaded)
{
Console.WriteLine("waiting");
await Task.Delay(10);
}
Console.WriteLine("complete");
browser.Document?.GetElementById("DropDownList1")?.SetAttribute("value", davaType);
browser.Document.GetElementById("DropDownList3")?.SetAttribute("value", tarafType);
browser.Document.GetElementById("DropDownList4")?.SetAttribute("value", year.ToString());
browser.Document.GetElementById("Button1").MyClick();
await browser.WaitPageLoad(10);
Console.WriteLine("Im DoneHere");
}
}
You can use TaskCompletionSource to create a task and await for it after the page is loaded.
See: UWP WebView await navigate.
I have experienced this problem before and the solution I have applied is as follows;
private void waitTillLoad()
{
WebBrowserReadyState loadStatus = default(WebBrowserReadyState);
int waittime = 100000;
int counter = 0;
while (true)
{
loadStatus = webBrowser1.ReadyState;
Application.DoEvents();
if ((counter > waittime) || (loadStatus == WebBrowserReadyState.Uninitialized) || (loadStatus == WebBrowserReadyState.Loading) || (loadStatus == WebBrowserReadyState.Interactive))
{
break; // TODO: might not be correct. Was : Exit While
}
counter += 1;
}
counter = 0;
while (true)
{
loadStatus = webBrowser1.ReadyState;
Application.DoEvents();
if (loadStatus == WebBrowserReadyState.Complete)
{
break; // TODO: might not be correct. Was : Exit While
}
counter += 1;
}
}
You need to create only one separate thread for WinForms. Other threads will be created by individual browsers themselves. What you do need is handling their DocumentCompleted event. The first time the document completes you enter and submit data, the second time it completes you get the result. When all browsers finish, you exit the winforms thread and you're done.
Note: To launch bots from winforms thread, I made use of Idle event handler, just because it was the first solution that came to my mind. You may find better way.

And how can i report to the user that there was a problem and that it's trying over again ? And should i just do it like i'm doing it now reseting everything and calling Init() again or should i use some timer and wait some seconds before trying again ?

In both cases where i'm using try and catch if it's getting to the catch i'm trying over again the whole operation by reseting the Lists and calling Init() again.
Then in form1
ExtractImages ei = new ExtractImages();
public Form1()
{
InitializeComponent();
ProgressBar1.Minimum = 0;
ProgressBar1.Maximum = 100;
backgroundWorker1.RunWorkerAsync();
}
events of backgroundworker
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
if (backgroundWorker1.CancellationPending == true)
{
e.Cancel = true;
return; // this will fall to the finally and close everything
}
else
{
ei.ProgressChanged += (senders, eee) => backgroundWorker1.ReportProgress(eee.Percentage, eee.StateText);
ei.Init();
}
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
ProgressBar1.Value = e.ProgressPercentage;
label7.Text = e.UserState.ToString();
label8.Text = e.ProgressPercentage + "%";
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if (e.Error == null)
{
ProgressBar1.Value = 100;
}
else
{
}
}
Another thing not sure if it's a problem. When there is no a problem with the class i see in form1 in label7 all the codes running from the first to the last.
But the progressBar1.Value and label8 both are getting only to 97% so i need in the completed event to add the progressBar1.Value = 100; is that fine or there is a problem with the reporting calculation in the class ?
For the 1st question:
Better catch the exception at client side and display the error msg, 'cause you probably need to control your program behavior accrodingly when sth went wrong.
Consider this: if the DOM struct of the page changed, according to you code, your program probably throw expections, with each exception catching, client.DownloadFile is excuted for one time, if this happens, u will need to know what go wrong, and if u donot change ur code behavior, such hi-freq client.DownloadFile excution will cause the firewall of the website block ur ip for a while.
Add a timer at client side is a good idea i think.
For the 2nd one:
did u define how to handle RunWorkerCompleted event?
I'm having an issue with altering the value of a string array based on what radio button is selected, it's written in C# using Visual Studio 2013 professional.
Basically all that needs to happen is if the radio button called "smallCarRadBtn" is selected, then the string array call "carSize" has to hold the word "Small", and likewise for the other two radio buttons "medCarRadBtn" and "largeCarRadBtn".
At the moment it is telling me:
"Cannot implicitly convert type 'char' to 'string[]'
I have 'highlighted' the area that contains the code for this with asterisks'*'. Any help would be appreciated.

carSize is an array of strings but you are trying to assign it a char:
carSize = ("small"[entryCount]);
Here the "small" is a string, and "small"[entryCount] returns the character at the index entryCount
You should change carSize to char[] if you want to stores characters, and set the elements using indexer instead of assigning the array directly. Or if you want to store the text + entryCount then you should concatenate strings:
carSize[index] = "small" + entryCount;
Or if you just want to set carSize[entryCount] then:
carSize[entryCount] = "small";
I am completely new to scripting in sound forge. I have a requirement of mixing 2 .wav files.
For example, 1.wav file mix with INVERTED 2.wav file.
I need to get the statistics of the resultant mixed output file.
Statistics like minimum sample value, maximum sample value for all the channels.
Below i have the code to mix 2 .wav files. But the 2nd is not inverted.
Can anyone please help me on the scripting for the above in C#?
Or if anyone can share a document with the standard API's available for sound forge scripting also will be helpful.

public class EntryPoint

//choose the first file.
OpenFileDialog openFile = new OpenFileDialog();
openFile.Title = "Open the input file.";
String inputFilePath = String.Empty;
if (openFile.ShowDialog() == DialogResult.OK)
{
inputFilePath = openFile.FileName.ToString();
}
OpenFileDialog openOutputFile = new OpenFileDialog();
openOutputFile.Title = "Open the output file.";
String outputFilePath = String.Empty;
if (openOutputFile.ShowDialog() == DialogResult.OK)
{
outputFilePath = openOutputFile.FileName.ToString();
}

ISfFileHost file = app.OpenFile(inputFilePath, false, false);
long fileLen = file.Length;
SfAudioSelection asel = new SfAudioSelection(file);
file.DoMixReplace(SfAudioSelection.All, 1, 1, backFile, new SfAudioSelection(0, file.Length), null, null, EffectOptions.EffectOnly | EffectOptions.WaitForDoneOrCancel);
backFile.Close(CloseOptions.DiscardChanges);

Using the below code the requirement can be achieved.
Requirement was:
1.wav file mix with INVERTED 2.wav file. Get the statistics of the resultant mixed output file.
Statistics like minimum sample value, maximum sample value for all the channels.
