• Visual Studio Express Editions About using C# script inside C# applications.

  Hello, I need to use C# script (without compile it in DLL or EXE file) inside C# applications. I need also that C# applications and script can comunicates each other. I'd like that my application can also execute the script step by step, and read/write its variables. In other words I'd wanna try something like previous versione of Visual Studio, where Visual Basic 6.0 applications can execute JScript. Is it possible And if yes: how Examples Thank you for help. Toni You may want to have a look at the items in the System.Reflection.Emit namespace. It's probably not exactly what you'd consider C# script but it may serve your purpose. These classes allow you to compile and run code generated by your program. The description from MSDN al ...Show All

• .NET Development using datasources during runtime??

  Greetings, I want to host data Sources wizard in a WinForm so that the user will specify data sources during run time… How can I do this Hi, As far as I know you cannot rehost the wizard in your own app, you have to create your own. It's actually not that difficult. The whole purpose of the dialog is to create a connection string. Look at the connection strings of the data sources you want support and add the appropriate controls to let the user enter the username and such. When the user clicks on the Test button, use a DbConnection to test the connectivity. If you want a dropdown for the list of databases you'll have to execute a custom sql command for each db you want to support ...Show All

• Visual Basic Referencing a Form on a Seperate Thread...?

  I converted my code from VS2003 to VS2005 and came across Cross-Threading problem, which previously did not occur in VS2003. I am developing a Client/Server style application where a great deal of computations takes place in either application. I designed a "Progress Form" that is used to, well you guess it, display the progress of some work. In an attempt to create code that could be universal used by any application, I decided to create a Class. I have a "Thermometer Class" that manages all the interaction of a "Thermometer Form". There is a reason why I used this duel object method of creating my "Progress Form". I want my progress form, when displayed, to lock the GUI but not to block the thre ...Show All

• Visual C# Dynamic Variable's Type Declaration

  Hi, Given name of type, how can I declare a variable with this type Let's say that classes B,C and D derives from A. Given textual input "B", I'd like to declare variable as following: List<B> myList = null; Thank you You've got it right. Somehow, I'm feeling that there should be a "c# language" solution for this problem - "dynamic T" I tried to "dig" and nothing came up. I'm facing this problem while handling dynamic creation of "controllers" to orchestrate scenarios. When each scenario covered by a controller, it's very convinient to store "controller" metadata (all kind of identifiers) out of the source ( ...Show All

• Visual Basic Need advise on what class to use

  Hi, I need to write an application to perform imaging of memory cards (up to 1 GB). The requirement is for the application to capture the entire image of the memory device into a file, all partitions included. i.e. if I have an 256 MB SD Card, I must write in all 256MB of the card into a standalone file The original and the image must match byte for byte. I've tried using stream reader to do a simple test (see extracted code below): Dim strmRdr as StreamReader strmRdr = New StreamReader("\\.\F:", System.Text.Encoding.Default, True) However, I was given the following error: FileStream will not open Win32 devices such as disk partitions and tape drives.  Don't use \\.\ " in your path. Hence, can anyone advis ...Show All

• SQL Server InfoPath 2007 and endpoint yielding HTTP authentication failed.

  I created a HelloWorld like example using InforPath 2007 and endpoint with SQL Server 2005. Very simple example. I created a stored procedure that took in one parameter, a datetime field. This parameter is then inserted into a db table that has two columns, an id column and a datetime column. I took the store procedure just discribed to create an endpoint. Cool. The WSDL is showing, I'm feeling good. I go to InfoPath and make it so that submit a datetime to the webmethod associated with the endpoint. The data table shows one more row has been added and it is the datetime I sent from InfoPath. YEA!! I go to the Event View and see that I have an error message. The message is HTTP authenticaiton failed. [CLIENT: 10.8.2.26]. Bummer! ...Show All

• Windows Forms .NET 3.0 Breaks ClickOnce

  Ever since I installed .NET 3.0 RTM, only users who have .NET 3.0 can run my ClickOnce applications. Please note that none of these applications are using 3.0 features. Also, I do not see .NET 3.0 in the list of redistributables and the Update link in VS 2005 goes to a dead page. I tried uninstalling .NET 3.0, but once I did that VS 2005 would no longer start. It silently dies after showing the splash screen. Suggestions Jonathan Allen In order to target .NET 3.0, you need to install the Visual Studio Extensions for .NET Framework 3.0 (WCF and WPF) . The tools install the project templates, visual designer and Intellisense support etc. for .NET 3.0 technologies. In addition, the Publish ...Show All
