Visual Basic How to secure sensitive data in connection string?
Hi. I am creating Windows Application using VB.NET 2005 When I add new data source to my project using, data source configuration wizard it asks if I want to exclude the sensitive data in the connection string.

But how can I encrypt or set these information in the application securely I seen alot of examples done w/ ASP.NET (encrypting web.config) but I can't find any for apps.config. Thank you. Thank you for your help. I looked at several articles and this is the solution I came up with. I added following codes to enrypt app.config, but something funny ...Show All
Software Development for Windows Vista IShellWindows behaviour changed under Windows Vista?
Hi It seems to me like IShellWindows only enumerates "true" Shell Windows under Vista when UAC is enabled. Internet Explorer Windows are ignored, unlike in previous Windows versions. If I disable UAC completely (via msconfig), it works as under Windows XP. However, when UAC is enabled, no matter what user rights I have tried, it behaves as described above. Is there a way to elevate the rights of an appication so that it can enumerate the IE windows Or is there another way to enumerate all open Internet Explorer windows in Vista and access their IWebBrowser interface Thanks in advance, Robert PS: I have posted this under "Internet Explorer Extension Development" a few weeks ago, but I got no usable answers.

Visual C# Thread Safety and Collection Problem
Hello, I'm working on a Network Application which holds all the connected clients in a Dictionary (Collection) and when Clients connect or disconnect this collection needs to be Modified as per requirement. All works fine with small work load e.g if a single client connect or disconnects or may be 2. But when a bunch of Clients say 30 disconnect altogether then I get Excetpion Collection Modified, Enumeration Operation may not execute come thing like this. I know this is all due to Thread Safety where multiple disconnection occurs. I have used lock and thought its enough but I'm getting this error. Here is my Code: public void Disconnected( ClientProxy sender, EventArgs e) { try { lock (clientProxyDictiona ...Show All
Visual Basic Classes and Custom Controls
Yes i was wondering, is it better to make classes and your custom controls or just code everything into a project. I been working on a program for a hardware store, and I haven't done any custom controls, or classes (dlls), do you suggest moving forms and operations to classes and to custom controls . What Pros and Cons would each one give later Any good tutorial that would explain on the correct creation of dlls and custom controls Just for info, the database program for the hardware store is very small, the program ocupies about 1mb of hd space, this does not include .Net 2.0 or the crystal reports distribution package. Any guidence would be apreciated. Thanks in advance, and have a nice coding week. ...Show All

.NET Development dataadapter.update not updating dataset from datatable new row
I’m having a problem getting my dataset to update by adding a new row to the datatable. I have manually created my connection.

Visual Studio June GAT Installation Issues
Hi All, I had major issues in in uninstalling previous version of GAX.

I have removed every file or registry entry which has 81f72285 in it. No success. I have installed and installed VS 2005 twice but still can't get around this problem.
