• Visual Studio Team System Problem Unit Testing ASP.NET Application

  I'm trying to unit test my ASP.NET application. I have two problems: I need my application's HttpModules and HttpHandlers to have total control over the requests as my ASP.NET application is actually an Atom server. Effectively I have IIS forward all requests to ASP.NET; when I try to run my generated unit tests that have [HostType("ASP.NET")] attributes I get an error when accessing the VSEnterpriseHelper.axd file (information invalid ). I have code that does internal functions in the ASP.NET app that I need to test without actually invoking URLs at all. So I just removed the [HostType("ASP.NET")] and [UrlToTest("...")] attributes and ran the tests. Now the problem is I need a way to access my web.config from within the unit tes ...Show All

• Software Development for Windows Vista How to call & pass the parameter to a workflow inside a workflow

  Hi I have a workflow inside which i m calling two another workflow simultaneously. The problem I am facing is that I am unable to pass the parameter to the child workflow and also unable to returning the parameter from the child process back to the parent process. Also if anybody have any link from where i can get the sample which can solve my problem. Plz tell me.

• Visual C++ Editing Array of string values from CSV file

  I'm new at this so please bear with me. I have a CSV file that contains about 500 rows and 50 columns. I need to keep all the rows but only keep columns 1,2,3,4,6,7. I've opened the CSV and stored each row as a single element in a one-dimensional array. What I need to do now is search through those array elements and remove everything except column 1,2,3,4,6,7. Am I approaching this problem correctly If so, how do I proceed I'm stuck. I adapted your sample code somewhat. This should get you further. using namespace System; using namespace System::IO; using namespace System::Collections; using namespace System::Collections::Generic; int main() {     StreamReader^ reader = gcnew Strea ...Show All

• Visual Basic System.Data.SqlClient.ConnectionPool.CreateConnection

  Hi, I had make one Desktop application in VB.net, having 6 threads simultaneously running. And each thread connect to sql server and stored the value in DB at every one second.

• Visual Studio Express Editions combobox selectedindexchanged fires when filled with dataset

  I fill my unbound combobox using a dataset on form load. When the form loads it automatically fires the code in the combobox selectedindexchanged event without the user changing the selection. Obviously it is recognising the fill as part of the event. How can I get this code to fire only when combobox is changed manually Thanks Thanks Mahi. That sounds about right.

• .NET Development Cryptic exception...A call to SSPI failed...

  Hi All, Been working this issue for a few days now, here's the deal. I have a bit of VB.NET code that uses an SslStream object to communicate with a Java application over SSL. The Java application uses JSSE to facilitate SSL. The VB.NET SslStream code works fine on any machine thus far except for one. On this particular machine, when the VB.NET code calls the AuthenticateAsClient method, the following exception is raised: System.Security.Authentication.AuthenticationException: {"A call to SSPI failed, see inner exception."} Data: {System.Collections.ListDictionaryInternal} HelpLink: Nothing InnerException: {"Invalid flags specified"} Message: "A call to SSPI failed, see inner exception."

• Visual Studio How does assembly ref debugging work?

  I copied a dll I had created to another folder and then attached a reference to it (from a WinApp). If the dll build is Debug I am able to step into it and it even finds the original path of the source code. A Release config, obviously, cannot be stepped into. I opened up the dll in ildasm and I didn't see anything that helps VS2005 track this. How exactly does this happen Thanks for that pointer. I looked at the modules window, and yes, the symbols file was loaded. But it is from obj/Debug folder of the original project that contains the source for this assembly. I copied the dll alone to another folder. How does the debugger manage to figure where the original symbols file was created ...Show All

• Visual C# does managed code take precedence over native code?

  i wrote a small demo C app that sends a message and a struct to a managed C++ dll. this C++ dll marshalls over the message and struct to a managed struct and sends it to a C# assembly that just prints out the values of the struct (to see that everything came over ok) and sends back a string reply, it also prints some debug text to console. before the call to the C++ dll, i make a few calls to printf to print to console. when it runs, it does the C# assembly debug statements before the native C printf statements. other than that everything looks ok. does managed code take any sort of precedence over native code the whole thing is a proof of concept. so the quick and dirty: ok so i have a C# assembly, it ...Show All

• Gadgets location.reload(true) kills the System object?

  I stuck a reload button in my gadget so I could easily refresh it to see the effects of changing something in the code. The onclick handler for the button is onclick="window.location.reload(true)". This does in fact reload the HTML and JS. But it seems to also kill the System object hierarchy. The code "Display.innerText = System.Gadget.name;" works the first time the gadget is added to the sidebar. Then I click my reload button and I get an error trying to access the System object. If I wrap the call in a try/catch and look at the error, it says "'System' is undefined". If I then close the gadget and re-add it to the sidebar, the System object comes back. I'm running the final version of Vista Ultimate ...Show All

• .NET Development Should I reinstall?

  I am building a simple prototype using a complete install of Visual Studio Team Edition, connecting to an Oracle database using the Ole DB provider for Oracle. When I add a typed dataset via the add data source command, the added dataset (although it is correct in terms of class definitions etc) does not display at all in the designer. Instead an empty hole appears and when you click on it (or try to add datatables, relations, etc) it says 'exception thrown by the target of an invocation'. Tried copying the project and testing it on a different machine: same result. Any way of determining if the designer is malfunctioning, or does it not work with the Ole DB provider, any general help Install was done via Novell, btw. ...Show All
