• Software Development for Windows Vista How can a replicator be used in a XOML only workflow?

  I can bind a Replicator's InitialChildData property ok but how do I bind a replicator's child activity property to the data. For example, if the InitialChildData is a List<string> and I drop a ConsoleWriteLine activity into the replicator how do I bind its Message property to the data in order to write out each of the strings Michael - you'd need to have another activity (or have a custom Root activity) that had public methods that matched the signature of the Replicator's eventhandlers and had the code to do what you'd want to each of the children activities. ...Show All

• Visual Basic Strings

  How do i capitalize the first letter in a textbox or combo box if the characters are in lower case. on the textChanged event of either control, one way to do it is to check to see if there is text, if so, then do a ToUpper on the first character. Example: if Me.theTextBox.Length = 1 then    Me.theTextBox.Text = Me.theTextBox.Text(0).ToString().ToUpper()    Me.theTextBox.SelectionStart = Me.theTextBox.Text.Length 'so the cursor is at the end of the text end if   you could also do this perhaps: if Me.theTextBox.Length = 1 then    Me.theTextBox.Text = char.ToUpper(Me.theTextBox.Text(0)).ToString()    Me.theTextBox ...Show All

• Software Development for Windows Vista Music Playback in Vista Problems

  Since installing Vista Ultimate, simple music playback using various programs is hampered by digital stuttering (similar to Max Headroom) from all music players. Vista can't get through a single song without these hiccups. Occurs in: Media Center; Rhapsody; Winamp, WMP 11; iTunes about every 30 seconds. My system is Windows Premium Ready; Acer Aspire 9800 (20" notebook) Dual-core T2600; 2GB RAM. Hardly lacks power; drivers not an issue on any of the aforementioned programs. Anyone have this same problem, or hints at a source of the problem Very interesting. This switch did not fix my problem all the way, but definitely had an impact. It has lessened the lag time significantly. It does point ...Show All

• Visual Studio Express Editions illegal else if statement?

  Hi. I'm relatively new to programming and I was making a program for class to display a "receipt". This involved the user to input the amount of cashed tendered and I had an if / else if statement for if the amount was less than the amount owed. However, each time I try to compile, it tells me I have a illegal else if statement and I just can't figure out why! Here's the code, hopefully someone can help me out.

• Visual Basic efficient storing and programming for data

  Rebuilding an application from DOS to Visual Basic, I have several questions, mainly concerning storing the (relational) data (SQL). If I want to reuse code, I could use classes. I.e.: there are employees, customers, company's. They all have names, adresses, phone numbers, etc. I could build a class with these fields and create other classes which reference to this one. But how do I save the data stored in the objects created from the classes to an SQL server By programming to populate each and every field of database with the data in the objects This doesn't seem very efficient. And if I add a field, I have to rewrite the code. Could you just store the entire object as a record in the database Databinding is another option, but then I al ...Show All

• Windows Forms Cannot add table adapter to datatable

  If I have a dataset in my project, and I've added a datatable to it, when I right click on it the option to add a tableadapter is greyed out. It seems as though I have to add a tableadapter to get a datatable with tableadapter connected to it. What if you already have a datatable in your project and want to add a tableadapter to it I had a recommendation to install SP1, and I did, but it did not fix the problem. No response since then. Well, you can always use the DataAdapter instead of the TableAdapter. It amounts to the same thing basically and is not specifically tied-in to your DataTable (which I think is preferable anyway ... I don't believe that a DataSet should know anything about where the data cam ...Show All

• Visual C# 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).

• Visual C# native types

  Hello. I created a simple dll which export a single, simple, unmanaged class using C++ and VS2005. The class contains only simple data types (int and float). I compiled this class with /clr flag. Now I want to use this class in a C# application. After I added a reference to this dll in C# application I'm able to instantiate an object of this type but I can't call any method of this class. (Error: the class dose not contain any definition for methodName). Using ObjectBrowser I can see all methods of this class. I written a simple managed wraper class, and this works. There is any way to work around without writing a wraper class I'm wonder way I can instatiate the class but I can't call its methods. Thank you. ...Show All
