• Visual Studio Express Editions Program freezes before all possible numbers are generated.

  I wrote this little program as an experiment to generate a different random number each time a key is pressed.  If user keeps pressing key, it should continue until all 30 numbers have been selected but it freezes up before then.  Why (I know how to do this using an array, but I just wanted to experiment with a different technique.) Module Module1 Sub Main() 'buggy - stops and freezes before 30 Dim rand, ind, count As Integer Dim srand, st, norep As String norep = "" count = 0 Dim randnum As Random = New Random Console.WriteLine( "Press any key to continue, Esc to stop" ) Do count = count + 1 Do rand = randnum.Next(1, 31) srand = rand.ToString ind = nore ...Show All

• Visual C# How to open a new window form?

  thank you for replay since you didn't explain really exactly what you are after, try this to open a new form, assuming if the form exists in your project: Form2 theOtherForm = new Form2(); theOtherForm.Show(); of course, replace Form2 with the name of the form in question you wish to show. You can also use ShowDialog(); to make sure that user cannot access previous forms until this form has been closed and will block the code executing from the caller until the form is closed: Form2 theOtherForm = new Form2(); theOtherForm.ShowDialog(); ...Show All

• SQL Server Web service to call integration services

  Hi, I'm hoping someone has tried something similar before. I am trying to run an integration from a remote computer using a web service. I have set up the web service and the bog standard launch package routine works fine. What i'd like to be able to do is to launch a package and also specify any parameters associated with it. I have the following code which is identcal to the main launch sub with the exception of an extra argument (jagged array of varible name and value variablePair[4][2]). It also processes the variable array and sets them on the DTSPackage object.

• Visual Studio Express Editions Breakpoints do nothing

  I can't get breakpoints to work. I can set them, but they don't actually do anything (the program does not stop when it hits a breakpoint). As far as I can tell I am building and running in debug mode. I've tried re-installed VC++ 2005 Express several times. I've never gotten breakpoints to work. I'm a noob. Keep that in mind if you try to help me. OK, there are two things you can try. The first is to set a break point right at the start of the main function. The second is to use the f10 key to step through the program to see if you actually hit the breakpoints you set. ...Show All

• Visual Studio 2008 (Pre-release) Setting an XElement's value

  In section 2.7.3 of the XLinq Overview document of the May CTP release, a method named ReplaceContent is discussed for the purpose of updating an XElement's value. No where does it mention setting an element's value via the XElement's Value property. Is this a no-no It does work. Here is a code sample: XElement auto = new XElement ( "Automobile" , new XElement ( "Make" , "Ford" ), new XElement ( "Model" , "Mustang" ), new XElement ( "Year" , "2004" )); Console .WriteLine(auto); auto.Element( "Year" ).Value = "2006" ; Console .WriteLine(auto); And here are the results: <Automobile> <M ...Show All

• Visual C# Application Events

  I am running an application that has the capability of calling an external DLL when certain events occur. The application is not written in Managed Code, basically in the app's ini file you specify the .DLL you want it to call. The app needs to call 2 methods contained in the .DLL. My question is how would I go about writing this DLL in C#, is it even possible The docs give examples in C++, but they are way out of my league. Anyone have any resources they could point me to, to get me started Thanx. In Visual Studio 2005... 1) Add the third party dll as a reference to ur project. 2) Then right-click the added reference. 3) Select the option "View in Object Browser".
