• Windows Forms A challenge. Text to binary, and back.

  In my windows forms application I need to develop a method to convert a string to binary and then back again. This is going to be a simple way of user authentication to secure the data. Aside from that conversion I will be doing another conversion with it to secure it even further. The only part I need to know how to do is the binary to text and back. Here's my logic: User inputs password -> Converts to binary -> my conversion -> finalized password User retrieves password -> my conversion -> converts to string -> original password Okay, it displays the full byte array in the second text box like it is supposed to. Now I am having problems getting its string value from the text box content. (This binary data is goin ...Show All

• Visual C# Convert string to operation

  Hi! Is it possible to convert strings to operations in a relatively simple way For example convert this string: string OperationInString = "3+3+9"; somehow, so I get back "15". Thanks in advance. ;) This is working fine for most of the operations, except operations like (1280-2)/2^7. It is replacing ^ with + sign and calculating the result.

• Visual Studio 2008 (Pre-release) Displaying DataTable in run-time

  Hi, I've got the following issue: My application is intended to show any table from the database. It means that the structure of the table is only known in run-time. I looked through the samples, but all the examples contain DataTemplate definition in XAML file that is not my case. I browsed the documentation but did not manage to fing the way how to create DataTemplate programmatically. Are there any ideas how can I display a table when its structure is only known during runtime. TIA remove the highlighted line GridViewColumn gvc = new GridViewColumn (); gvc.Header = "column0" ; Binding b = new Binding (); // b.Source = ds.Tables[0]; b.Path = new ...Show All

• Smart Device Development cannot establish network connection

  Good Morning, I have written a very simple web service and I cannot connect to it. However, I can connect to it via the brower and from the Reference.cs of the project.  Yes it does what it is supposed to: Add two numbers .

• Software Development for Windows Vista Activity Naming standards

  In a WF all activites have to have unique names. Was the concept of naming containers considered In my State Machine WF for example I have several places where I use SetState activities. Say I have 5 places where I use SetState to target a ProcessOrder State. I am not able to name all 5 activites SetStateProcessOrder, yet they all are used to do just that. I have found myself adding a suffix of the parent State or Activity name to all of my activies to emulate naming containers. I dont really like my solution. I would prefer something like that to happen for me automatically. Is there any guidance on Activity naming Perhaps some proposed standards We are using the same model as a Windows Form or User ...Show All

• SharePoint Products and Technologies new default template for mySite

  Hi All, how can I update the default template for new mySites After studying the "Office SharePoint Server 2007 Administrator's Comnion" I see only a programaticly approach (the Object model). Is there any possibility for customers to modify and "save as default" Thanks in advance, Jens I have the documentation for this but have yet to find the time to install this.

• Windows Forms How to have only a single instance of form running

  Hello guys, I have a Winforms application written in managed C++. I would like to only have one instance of my application running on a given system at a time. The reason being opening another instance of my form can really mess up the environment I'm working in. How can I do that I'm guessing it wont be very hard to do. Appreciate your help!! Figured it out. The mutex was being prematurely discarded on other systems (strange). Anyway, I added a GC::KeepAlive(mutex) to keep a hold of the mutex as long as its running. It works like a charm now. ...Show All

Using "default" WILL dramatically limit throughput during load testing. Josh ...Show All

• Visual Studio Team System Can I use the XML/XSD schema as a source for data genaration?

  I have some XML/XSD schema which has table definition. Can I use this schema in place of the RDBMS table for generating the data And is it possible to have this data generated in the XML file Right now we either reverse engineering the schema from database or import it from Sql Script. And there is no direct way to import the schema from XML/XSD. A workaround is that you can write your code to create sql script so that it can be imported. For data generation, there is no direct way to generate data into xml file. You can generate data into the database first and then export them into xml file. Thanks, ...Show All

  Hi, i have a label and a progress bar in a statuStrip in my RSS Reader application. I want that a message like "Update in progress" is displayed in the label during the update of the RSS feeds. So, before i start the update, i simply set: statusLabel.Text="Update in progres..." and, when the update is complete, i do: statusLabel.Text="Done". The problem is the message don't appear!

But there is nothing to do, when i press the refresh button of my application, the label text still remains "Done". What can i do The progress bar near the label works perfectly too!
