• Visual Studio 2008 (Pre-release) Calling "transactional web services" within a series of database update calls - is Indigo the only way?

  SCENARIO Suppose I call the following method in a ServicedComponent: public void DoMixedUpdates() {     DoDBUpdateA();     DoDBUpdateB();     CallWebService1ToDoDBUpdateC();     CallWebService2ToDoDBUpdateD();     DoDBUpdateE();     DoDBUpdateF(); } All 6 calls perform DB updates but the middle 2 calls call "plain old" ASMX web services that each then call a component that performs DB update C and DB update D. QUESTION On the current shipping versions of Windows Server 2003, does a) .NET 2.0 with WSE 3.0 or b) .NET 2.0 without WSE 3.0 support the "transactional web service" scenari ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to make a main menu?

  How do I make a main menu that you see in alot of games these days I'm kinda curious... I haven't tried it yet but I think something like the following should work: - Declare a boolean boolGameStarted or boolShowMenu - Create a custom menu class or something else, ie a simple array, that holds the currently select option - Depending on the boolean, draw the menu options, e.g. strings or a sprite, and draw the currently selected option in a different color for example (ie. different color string or tint a sprite) - In your code that handles the keyboard/gamepad menu, depending on the boolean, check for input (up or down, start/enter, etc) and change the currently selected menu option in the menu class or array ac ...Show All

• Visual Studio Express Editions Looping through filenames

  Hello, I developed an application that creates a webpage for the end user after they simply fill in some text fields (among other fields, too). This program is a piece of a much larger application. Once delivered to the customer, it will be their responsibility to maintain the webpages using this application. The webpages represent products that they will be selling. All that said, I need to be able to create a unique filename everytime a new prduct page is created. The format of the file name is such: AM_001_BEV_ProductFullName.htm AM = AMbient product 001 = unique Ambient product identifier. Say the files are saved in "c:\Product" directory. I currently have it so that I read all files in this directory tha ...Show All

• Visual Basic ComboBox Frustration: Setting a default "SelectedIndex" when adding a new record refuses to work.

  Help! This is a very frustrating problem. Ok I have a typical databound Form with a bound ComboBox bound on the form Load event. I have a typical BindingSource and BindingNavigator Control with an "AddNew" button. When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting... mycombo.selectedindex = 0 I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to  -1 As an experime ...Show All

• .NET Development Need HELP in understanding the power of ASP.NET/C#

  Hi, I am producing a Web application that must be able to upload and download files to/from the web server. These files must be downloaded to the client hard disk for future editing by the user. The upload/download process must require a minimum amount of user interaction and where possible be done fully automatically. I have achieved the uploading/downloading by writing a standalone windows application that makes a Web/HttpWeb connection for each action. The file (or in some cases just data - for the download) is then either downloaded to the client hardisk or uploaded to the webserver hard disk and the connection is closed. This is all driven from the standalone application - ie: the user selects upload or d ...Show All

  I have a stored procedure used to lookup ad's similar to ebay. We want to allow the customer to search based on their zip code in relation to the items location.

• Visual Basic 2 Questions: Drag and Drop File Path AND SQL Server Update Database

  1)What code would I use to get the file path of a file that is dragged and dropped into a form 2) I have a certain table represented in an application as a listbox. On the form opening, the listbox is filled with the contents of the table. How can I have it that the table is saved with the listbox items at the form closing (what code , i'll place it on Form_Closing) Yes. You may also want to modify the Drag_Enter event handler to check the data (similar to the code in Drag_Drop), and not set the effect value if the length of the array is not 1. That way you will only see a drag_drop event if they drop 1 file, and if they try to drag multiple files they will get a visual indication that they can't do this. -Scott ...Show All

• .NET Development App.Config - Enterprise Library - Security Issues

  Hi guys, I am just trying educate myself on the usage of the Cryptography Application Block from the Enterprise Library. When you select a symmetric algorithm and then define a key file using the Enterprise Library EXE, it modifies the contents of your application's app.Config file. When examining the app.Config file, I can tell the name of the symmetric algorithm used and the location of the keyfile. Forgive my noob understanding but doesnt this pose as a security risk Since the location and the name of the symmetric algorithm are presented in clear text How does one go about protecting this type of sensitive information within the app.config file. Is there an enterprise library method that I could use to encrypt this section of the a ...Show All
