c# - TargetParameterCountException with Invoke() -

-

I am trying to update a control, but a cross threading exception error (note: cross-threading exception error Only occurs when debugging with VS, when I just run .exe, works fine). That's why I've gotten to the eye, and the invention method has reached. Now I am getting this error.

I am trying to use the extension method: 

  public static zero invoke & lt; T & gt; (This TC, Action & lt; T & gt; Action) where T: Control {if (c.InvokeRequired) c.TopLevelControl.Invoke (action); Other verb (c); }

Use the code below to update a progress bar. 

  pb.TextLabel.Invoke (c => c.Text = "copy" + path. GetFileName (this.mp2File));

But I am getting the following error:

c# - Highlight all words containing a letter in a richtextbox -

How do I highlight all the words in a letter in a rich text box? If I want to expose the words that contain the letters "a", such as a hat or candle word, both words are highlighted, I am using C # on Winform. Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...

The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...
