• tt2lhp Help a newbie! Converting VB6 to C#

  Hi All, I've been given the unenviable task of converting someone's VB6 code for an upload form into C#. I'm not doing to bad at the minute but I'm struggling with some of the conversion. For example I have the following code (in C#): ====================== Hashtable strLang = new Hashtable(); Hashtable strAllowedExtensions = new Hashtable(); private bool SetLang() //*** SetLang() //* Add language strings to the array collection //*** { strLang.Add("INFO_FILE_SPEC", "- Is one of the following formats {0}, and is no bigger than {1}"); strLang.Add("ERROR_MAXSIZE_EXCEEDED", "The CV is bigger than the maximum size allowed."); strLang.Add("ERROR_INVALID_FILETYPE", & ...Show All

• raghava66 Fade background like WinXP

  I would like to simulate WinXP shutdown's background fade to grayscale. How can I achieve this on my app's quit when I ask user "are you sure you would like to quit" else return to full color. Thanks for any ideas If you play with form transparency you will get simular behaviour but not same. Hi, Did you manage to simulate it Bhanu. No Bhanu, I did not get it.

• dstorch foreach without Type

  Hello, I have a collection and I want to iterate all elements in it. Example: string [] arr = new string [] { "A" , "B" , "C" }; foreach ( string s in arr) Console .WriteLine(s); in the example the element type is string, because the collection is array of strings. is there a way to do the same as foreach does, but without declaring the type. something like: foreach ( s in arr) Console .WriteLine(s); some how make the compiler know that the type is the collection's element type.

• zensunni What's the difference ?

  Hi! I have SortedList implemented as a generic one like this: SortedList<int , string> myList = new SortedList<int ,string>(10); What's the benefit of having int instead of just int as a key Key can't be null so if I set: int a = null; myList.Add(a, "foo"); It will compile but still won't work. So should it be int I found it in a code but don't get why is there. Jedrzej Hi, Jedrzej int  is what called Nullable type , we can use nullable type more flexibly and with more convenience. (it has HasValue and Value properties) So, it is used as a kind of Generics. It is one of the "late breaking" features in C# 2.0. The details can be found in the C# 2.0 language spec .

• Bruno Kova&amp;#269;i&amp;#263; What time format?

  I got this string (14 bytes) as an output from a demo C# code I am trying to incorporate into my app. DateTime=12102006222639 It is 10/12/2006 but the rest of the string represents time. Is it possible to figure out by just looking at it or applying an operator the exact time represented by the rest of the string (6 bytes: 222639) Reading it so far did not make much sense to me. The presumed time is constrained by day time hours between 9:30 AM and 4:00 PM EST. Thanks. You are RIGHT. Although I haven't verified it yet, it crossed my mind that it could be the case right after I posted the question. You are right on the difference between New York and Greenwich, UK as well. It is 4 hours. Definitely some trading goes on a ...Show All

• Quadrillion How to find / locate a control on a form?

  Hi, I have a configuration file, which specifies which controls should be disabled based on certain criteria. The only way I know of getting a refernce to the control in the form is to recursively go through every control. Unfortunately, this is not a viable solution for me. Does anybody know if there is another way to access the control I need based on its Name property, or any other property Any outside of the box solutions are welcome. Thanks a lot. Lidiya indeed that becomes a problem. I guess you would need to get hold of the "parent" control, then do the same thing, using the controls[ controlName] and see what happens This is interesting.  I didn't know I could index into t ...Show All

As the title says... how do I calculate the amount of daily hours worked by an employee I'm pretty sure this is probably basic but I'm a novice and I'm trying to write a basic app to act as a weekly timesheet, either with VC# or ASP.Net I'm using DropDownLists to enable the user to select a starting hour and a finish hour.

• Daffodils Beginner questions about Serial.IO.Ports and multiple forms

  Hello everybody, I'm currently learning C# using Visual Studio 2005 and still have a hard time to get the big picture in this (new to me) object oriented world. I hope you don't mind answering me some questions that might be pretty basic in your point of view. I managed to write an application that reads commands (text strings) of a serial port and does certain things. I'm now in the need to make this serial port reader a background task that is always running, regardless which form is currenlty visible. I would also like to move the serial reader into a seperate class to keep the code a little cleaner. I read about the background worker task but I'm still confused whether or not this is the way to go or if there is an easier and ...Show All
