Does anybody know if there is some sort of bug or issue with the webBrowser activex control in .NET applications, in this case the embedded browser loads a web page that depends on javascript to play music previews. It works once but if you navigate to a new page in the system it stops working. Viewing the same site in just a normal IE ...
My application has a frame that is loaded/navigated when certain top-level buttons are clicked. The problem is, one of the hosted pages has a frame of it's own, and is messing with the outer frame's navigation bar (clicking back and forward navigates the inner frame, as well as the outer frame). Is there any way to have the outer frame...

Over the past year I have heard alot about Velocity and NVelocity. Reading their documentation and doing searches on the net hasn't given me the answers I was looking for. In what situation would I use this library in my development? What problem does it solve that didn't already have a solution? ...
My application receives strings that represent objects. I have to parse the strings to get the property values for the object I'm creating. Each object will have to know the specifics about how many attributes there are, what each attribute means, etc. However, I want to avoid having each class know about how to parse the string. I'd...
Is it at all possible in the middle of a function execution to set a pointer to the current stack (to be picked up later) and then release the current thread (without unwinding the call stack) and give it back to the thread pool? And then, have another thread pick up where that thread left off? I know it would mean that someone calling...
We're about to embark on development of a new product. Our current product is a conventional client-server winform app written using VB.NET. Is WPF ready for a business application? From what I've seen, it seems like it's harder to develop a user interface with WPF than it is with Winforms. But I suppose speed comes with experience. ...
I have a very common situation here. And for years I haven't found if what i am doing is RIGHT by industry standards.Consider an application which connects to the database, but where the connection string instead of being stored in some file/setting is being passed as a command line parameter at startup OR the database is browsed to at t...

I am now creating an *.aspx page that will present the output of a request to the Google Maps API. This output will be a polygon on a map that will be that US ZIP code. I'm wonde...
I'm using C#.NET to launch and control a Delphi-written executable. The Delphi application has a COM interface. I've imported the Delphi executable -- we'll call it DelphiApp.exe -- into Visual Studio as a resource. The following C# code works -- if no other instance of DelphiApp.exe is running: DelphiApp.DelphiAppClass da = new Delp...

I've got a Checkedlistbox, which is 3 rows high, and large enough to display about 5 elements. As long as I've got less than 15 elements, everything runs fine. However, if I add a sixteenth element, the checkedlistbox displays an horizontal scrollbar which takes 2 item rows, which means all the Items are now on only one row. Worse, if ...
I'd appreciate people's thoughts on a dilemma I've been struggling with ever since ASP.Net came out. In classic ASP, the layers of code were minimal. The ASP page contained HTML and script combined. The COM components contained business logic and DAO infrastrcuture. The asp pages themselves were messy, but everything was in one place...
I am having virtually the same problem as this: http://stackoverflow.com/questions/433281/c-update-combobox-bound-to-generic-list However, I am trying to change the displayed strings; not add, remove, or sort. I have tried the BindingList solution provided in the referenced question, but it has not helped. I can see the combobox's Dat...

Off the top of my head it could look something like that... var stmnt = new Statement(); stmnt .AddMaster("Customer") .Show("Firstname, "Last...

In my case, I need to access a magnetic card reader that would be attached to the client computer. The web-app would need to be able to access the reader ...
If you were writing the next 3d graphics intensive application in C# (like a 3d modelling and animation software), which one would be a better choice? If we consider C# as platform independent, then OpenGL seems tempting, but what about the performance, etc? Since the used language is C#, the performance is pretty crucial to consider. ...
Let's say my program is always passed a string of characters that represents a data table in Wiki syntax. Something like: {||Client:||ABC|-|Contact:||Joe Smith|-|Current revision:||1.0||} I don't want each one of my specific Wiki table objects (e.g., ClientContactTable, CustomerOrderTable, etc.) to know how to parse out | and - and...
