• applepie Deploying Web Site via "Copy Web Site"

  Hello, I've been developing a web site for a few weeks with a fair bit of DB work in it. The mdb file (sql express 2005) has grown to about 20Mb. When I go to deploy the site using FPE through the Copy Web Site method the IDE hangs on the DB and becomes unresponsive to the point of having redraw hangs etc. I have been able to deploy the rest of the site (and other sites, including those with smaller DBs) through selectively picking files/dirs and moving them to the server. Basically, though, a computer reboot, start IDE, copy web site, select DB & copy to remote kills the IDE everytime on this site. On some other smaller DBs I get the unresponsiveness, but after a few minutes it tries to redraw a bit, then eventually res ...Show All

• Brant Yin casting

  hey all, Just a quick question about casting and how it works. if is do String s = (string)someobject, what happens in the background i.e. some method is invoked intternally to convert the object to a string or what How does this work I tried to find the answer but no luck. Please help . Thanks sunny Hi it's not some hidden method... i'll try to give you an explanation that's not really technical but which can give you an idea of what i mean :) at runtime the type of the object is known... the object in itself is accessed via a "type interface" (interface meaning the collection of methods, properties, etc; this is not the c# interface) which specifies what methods, properties and so on you can access ...Show All

• hrubesh Number Combinations

  Ok. What I need is a method that discovers all the different combinations of any give set of numbers. For example, if my numbers were 1, 2, 3 all the possible combinations would be 123 132 213 231, ect. Can someone help A simple method would be appreCiated. In those examples I have to add classes. That is what I am trying to avoid. Here is a simple, recursive solution (up to you to implement it): - If you're going to construct all the possible combinations of n characters, all you need to do: - Find all the possible combinations of n - 1 other characters, and prepend the n-th charachter to that result. Here's an example in php: function permutations ( $string ) { $results = array(); // only 1 letter -> o ...Show All

• chakravarthy_b New to programming, need help starting this program. Any suggestions??

  I had no trouble creating the form, but I don't know where to begin with the code. Any ideas "Piecework workers are paid by the piece. Workers who produce a greater quantity of output are often paid at a higher rate. Use text boxes to obtain the person's name and the number of pieces completed. Include a Calculate button to display the dollar amount earned. You will need a Summary button to display the total number of pieces, the total pay, and the average pay per person. A Clear button should clear the name and the number of pieces for the current employee and a Clear All button should clear the summary totals after confirming the operation with the user.

• raj.ramesh Multidimensional Arrays

  Ok, my book really sucks I think. After struggling with an example in the book, I looked in the MSDN and searched these forums. I believe my book is wrong when it shows: int[,] student = new in[4][3]; I tried doing it that way but it errors. int[,] student = new int[5,4]; gives me no error and works. I am going to go with that. Unless someone can tell me that int[,] student = new in[4][3]; is indeed a correct format or what kind of a typing error it could be... The following also seems to be in the wrong format: int[][] x = { { 2, 3 }, { 4, 5 }, { 6, 7 } }; I don't think you can do it that way... You are more than welcome any time! Best Regards, Ok, now I almost have everything figured out wi ...Show All

• Jassim Rahma Formatting an Entire Solution off of a vs.settings file

  Wanted to see if anyone has any ideas. At work we have started developing some coding standards, so all of our code will look somewhat similar(braces, variable naming). One thing we cannot agree on is the location of braces...some of us like them on the same line, some on the next. And both sides of this are unwilling to compromise. I was wondering if there's anyway upon opening a solution I could run my settings file against it(so all braces are on the same line)...but then when i finish up a project I could run a different settings file(so all braces are on the next line) to match our standards. Or Vise Versa for a different developer... Thanks Hello All. Michael: No, you don't understand. Ma ...Show All

• sandeep437 Refresh Property Grid Values

  Sorry, but I had to repost this in the C# forum because no one answered me in the Windows Forms forum. Say I have an object, "oFoo", and I assigned oFoo to a PropertyGrid on my form. oFoo also has a .CurrentValue property. If I have a TrackBar (tBar) on my form, and when the user scrolls the TrackBar, oFoo's .CurrentValue is updated respectively. How do I refresh the CurrentValue so that it shows up correctly in the PropertyGrid Right now, the only way I can do that is by refreshing the entire PropertyGrid, but I would think there would be a better, more standard way of doing this. I've tried using RefreshProperties(RefreshProperties.All), but it doesn't even refresh the value in the property grid, so I'm pretty stuck ...Show All
