• .NET Development Configuration files

  I am used to working with the App.Config files. But there's one problem to them: They lack the ability to be encrypted and that's causing major security leaks. For example: Passwords for my database connection aren't encrypted. Is there anyone that has a configuration section class for me that supports encryption/decryption of settings in the configuration section Have a look at the following article: Encrypt Connection Strings in VS 2005 .Config files ...Show All

• Windows Forms Best user interface control suite?

  The application I'm currently developing requires a very robust and user-friendly interface.  I know there are many third party control suites out there, but which one is the best for the money   I'm looking for a package that supports dockable toolbars and windows/containers, preferrably multiple color schemes, menus with icons, tab interfaces, etc. (pretty much the standards.)  I've looked at Infragistic's NetAdvantage, Actipro's UIStudio, QIOS DevSuite, DivElement's Sandbar and Sandock, etc. If anyone has personal experience with any number of these (or other) packages, please share your suggestions and preferences.

• Visual C# How to determine if a generic parameter is null or default?

  The following code snippet gives me the compiler error: "Operator '==' cannot be applied to operands of type 'T' and 'T'" void Test<T>(T item) {    if (item == default (T)) // error here    ... }   What is the reason behind this compiler error I just want to see if the item is null for reference types, or default for value types. How can I do this You can compare the result of default to null, just not directly to a generic object. default will return zero if it is a value type, regardless of the actual value, and null if it is a reference type. Here is my understanding of how to use default: ...Show All

• Visual Studio Express Editions Connecting to a remote registry in VB 2005 Express

  Hello everyone, I don't know if it is possible in the Express edition to do any sort of remote work. I seem to have seen something somewhere that sounded like it was not possible. Anyway, here is what I would like to do: Connect to the registry on a remote PC and read a key. My program works on my local machine.

• Visual Studio Express Editions Can I Create an Access DataBase Without Access?

  I don't own Access and this is for Learning Purposes.... Can I create an Access DataBase with my own Schema(I guess that's the word) with VBE or any Other Way I downloaded Northwind.... Can I change Northwind schema without Access Thanks   Yes. I know you could do it with DAO. I'm not sure about ADO. Since ADO.NET is a little less faciliated in persisting, the USE of ADOX has been recommended to me for things like table creation and storage and I find that it works very well with VB.NET. I've installed systems based upon access databases on on target systems that did not have access. I ...Show All

• Software Development for Windows Vista SQL Persistence, Loading Workflows and Workflow Properties

One of those properties is the name of the user that initiated the workflow (it is passed into the workflow via the Dictionary<string, object> class. I have SQL persistence working just fine (well, I can't figure out how to 'auto persist', so I am manually calling 'Unload' when the workflow idles), and I run through the list of workflow IDs persisted when my application starts up.

• Visual Basic Bug: Accessing array of objects in a function

  When I try to use an array of objects through a function or certain types of subs, I get a NullReferenceException and a TypeInitialization exception. Any subs tied to a button do not cause this. This code explains better: This is in a module: Public checkBoxes() As CheckBox = {frmLaunch.uiCheckBoxDeveloper, frmLaunch.uiCheckBoxDebugFile, frmLaunch.uiCheckBoxAltDeath} This sub will use the checkbox array with no problem when called from a button: Private Sub Save_Settings( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles uiMenuItemSaveSlot1.Click, uiMenuItemSaveSlot2.Cl ...Show All

• Visual Studio Tools for Office Excel ListObject Problems

  I have a couple VSTO questions about the ListObject. Is there any way to remove or at least reformat the blue line that appears around a list object I understand the reason for it, and I think it will be OK if I could at least re-color it. Is there any way to get rid of the header row I doubt these two wishes are possible, is there any alternative I would really like to use databinding, as the alternative is to write tons of mapping code and as always time is short.

• Windows Forms Launching Application from a webpage.

  I'm not sure if I am on the right forum or not, but here is my question.  I have a windows app and a webapp.  The webapp pulls data into a datagrid.  When the datagrid is populated, the customer can click on a record and it needs to launch my windows application, and send it a variable, such as the id to that record, so that the application can launch and then hit the database and open the appropriate record. I know the best way would be for the webapp to just handle all data, but that can't be helped.  I know how to launch an application from a webpage, as well as to launch it by opening up an associated file to the app, ...Show All
