• George Stein Copy Folder to new location

  Help. I am trying to setup a sample application code I got from someone to copy a folder of a persons choosing from a dialog box, to a new location that is chosen from another dialog box. Currently this application works, but does something I don't want to happen. When the files are copied, it recreated the entire root structure to the folder instead of just coping the folder selected. Example: folder selected was c:\documents and setting\user\my documents\labels Copy to: c:\documents and setting\user\desktop The application created the file structure documents and setting\user\my documents\labels on the desktop instead of just the "labels" folder. Any insite would be grateful. The code at the top ...Show All

• Tryin2Bgood Referencing a form object in a Mainapp.exe from a form in component.dll

  Hi I have a form class in a .exe assembly (Main Menu Form A) and I have (Sub Main Menu Form B) in a class library assembly. Problem: I am having a hard time calling the Form A from Form B via the menu button, because I can not reference a .exe assembly from a .dll assembly without getting a circular reference error. What I tried: 1. From Form A: I tried to pass to Form B a variable(Me) to be set as the parent or owner of Form B. Then I tried to call instantiate a form A and show it, but that didn't work because of no reference to form A. 2. I tried to hide Form A and then from Form B try to just unhide form A, but that didn't work. Any assistance would be appreciated. I have spent several hours working on this, but it is ...Show All

• Yazici Code Simplification

  OK, first, i'm sorry if the thread name isn't as clear as it should be. The question is this: I have a code that uses up to 10 labels, depending on what the user would input at the beggining. (If the user says 7 labels, only 7 labels are shown, etc) I tried using this code at first since i didn't know how to use FOR, i had to repeat this 10 times, wich of course is huge since the only things that would be different are the "Dado1.Text" and the "Dado1.Visible" lines. (They would be changed for, Dado2, Dado3, and so on.) Dado1, Dado2,..., Dado10 are LABEL names. If i <= j Then temp = Int(Rnd() * 10) Dado1.Text = CStr (temp) If temp >= Int(Dificultad.Text) Then exito = exito + 1 End If ...Show All

• Keeep Out listbox items

  How can program a list box so that when a certain item is inputed the font color changes Drawing items with different colours is very straightforward once you set OwnerDraw to an appropriate value. The following uses Spotty's example, with the error corrected in btnDelete_Click, and will colour alternate rows with blue and red.

• migeold Date.Parse Can't Read "P" or "A" for "AM" or "PM"?

  I'm a bit baffled at something. The following code passes: Date.Parse("10 PM") But the following throws an exception: Date.Parse("10 P") I find this to be weird because in the ToString, the format string allows: Dim d as Date = #10:00:00 PM# Console.WriteLine(d.ToString("hh t")) That will output "10 P" It seems like a shortcoming that it can't process something that it can output so simply. Unless I'm missing something Why do they even include a single letter format if they don't recognize it as part of a valid time try with: Date .ParseExact( "10 P" , "hh t" , Globalization.CultureInfo.GetCultureInfo( "en-us" )) Try DateTime.ParseExact ...Show All

• harvard_isaac How do I create and post a custom message to the process message loop?

  I want to post a 'message' (preferably a custom message) from a child thread which I have created to the message loop in the main thread. This will allow the thread to interleave its communications to the main thread whilst the main loop is servicing other interface messages. I could do this with a form timer which generates messages but this needs a form. A timer running without a form just starts a thread each time it fires and I am back with the same problem. I can also achieve something similar using a 'Background Worker' but I want a variable number of threads so I can not use the event mechanism which needs a single instance. Using C and the Win API I used to be able to create a custom message and ...Show All

• Abdel1 Is it Recursion (or is it Memorex)

  I have a function called from a paint event that writes (DrawImage) on the control. It works ... so I thought nothing more about it ... U N T I L ... I went back a put a breakpoint into the code to Debug a problem, and then I noticed something strange. Instead of just working and exiting, it keep re-entering the function. I put a counter in it and it re-entered at least 14 time. I image it has to do with the 'Paint" event, but it certainly worried me. Here is the really strange part: When I took the breakpoint out, the counter now says the function is only entered once.
