• monkey1888 How to change the height of MainMenu?

  I need a graphical mainmenu and am able to do it with OnDrawItem(). However, I also need the mainmenu to be higher so that the sub-menu will show at a lower position and not block my graphical mainmenu. Any experts can teach me how Another way is to do it with PictureBox + Context Menu. The problem is I fail to hide a Context Menu when mouse leaves the PictureBox because when the Context Menu is shown, I simply cannot detect the mouse coordination.  I've checked this page already: http://www.windowsforms.net/FAQs/default.aspx PageID=3&CategoryID=3&SubcategoryID=71&tabindex=3   But mainMenu doesn't have this property http://msdn2.microsoft.com/en-us/library/system. ...Show All

• XNA Rockstar Casting Arrays?

  Hi, I have a method which returns an object array: object[] sortArray(object[] input, int[] order); And I want to be able to cast the array that it returns, for example: string[] array = (string[])sortArray(input, order); While this compiles, at run time I get a casting error (InvalidCastException, Specified cast is not valid). How should I be casting the array, or can I cast it at all Thanks. You should probably iterate through the objects in the list and cast each item separately. In untested code: string[] stringArray; stringArray = new string[objectsArray.Count](); foreach (object obj in objectsArray) { stringArray[objectsArray.IndexOf(obj)] = obj.ToString(); } here Is a mu ...Show All

• Tanzir Check if string contains valid year

  How do I check if a string contains a valid year only... I've the classic way but it seems it works only with complete dates. Here's what I tried: string MyString = "2001"; DateTime MyDateTime = DateTime.Parse(MyString); Console.WriteLine(MyDateTime); This code snippet throws an exception ! Any help would be appreciated. Hi Raihan, Your code throws an exception because 2001 isn't a valid date. It may be a valid year (you and I both know it is), but just isn't a valid date. You could intialize a new datetime object and then use the AddYears method to add the number of years. The resulting date will be January 1st of year+1 (a new datetime intializes to 1/1/0001) string MyString = "2001" ; ...Show All

• nbrege multithreading

  I need to do multithreading. It is my fist attempt. It failed. This is the setup: There is a form with tabControl and a few pages. There is a progress bar on one of them. It is supposed to measure progress of file downloading. WIthout multhithreading it is dead while the files are downloaded and then in the end it jumps to 100%. This is what I did. Everything compiled but the progress never was activated even after the downloading was over. In other words my code actually made the things worse. In the main form I put in this code at the start of procedure that is handling the download: ThreadStart threadDelegate = new ThreadStart ( Work.DoWork ); Thread newThread = new Thread ( threadDelegate ); newThread.Start ( ); T ...Show All

• breceivemail SELECT-INTO query problem

  Hi I have a SELECT-INTO query which I wish to add some additional columns to the destination table. I can create the table and add the columns after it, but I wonder how is it possible to add that columns directly with the SELECT query. Thanks in advance, farshad Hi, Are you working with SQL Server You can add an additional column like this: SELECT *, null AS AdditionalColumn INTO DestinationTable FROM SourceTable Don't forget to add an alias to your new column, otherwise it will not work. Although this works, the additional column is not always with the correct datatype. When working in SQL Server, it might be easier to create a new table by letting SQL Server generate a script of the source table for ...Show All

• guilhermecvm94558 Why doesn't IList have a BinarySearch method

  IList<> does not have a BinarySearch method, but List<> does. Is there any reason for that The reason I found out about IList<> not having a BinarySearch method is because I initially wanted to do a binary search on a SortedList<> SortedList<>. Strangely enough, SortedList doesn't have a BinarySearch() function, so I looked in SortedList<>.Keys. That's an IList, which also does not have a BinarySearch() method. I looked up List<> to confirm, and it does have a BinarySearch() method. I've worked around this using (SortedList<>.Keys as List).BinarySearch(), and that compiles, but I have not tested it yet. So, there might be an easy work around, but I just can't think of a good reason why ...Show All
