• Visual Basic Create a wizard in my application?

  Hi, I'm learning VS 2005 and developing an application that will include several wizards in it for the users. I can't find a tutorial for developing wizards with VB.NET - if you can help me, please email me a link or recommend a book that covers the topic I'd be grateful. Alternatively some advice would be useful: Should I just develop seperate forms that open and close in order of the wizard screens and make that my wizard Or is there a better/more streamlined method Thanks in advance AdrianB Hi, you can give this wizard framework a try and see if it suits your needs...

• Visual Studio 2008 (Pre-release) Suggestion: Full support for continuations

  I think it would be a huge benefit to C# developers if some future iteration of the language allowed full support for continuations. The ability to call/cc and throw with arbitrary stacks would work wonders for certain types of algorithms (compression, for example). Additionally, allowing the C# compiler to emit tail-recursive function calls would allow programmers work in continuation-passing style without fear of smashing the stack. These are largely abstract concepts inherited from functional languages, true. But it seems that with the addition of functional language features into versions 2 and 3 of C#, this would be the logical next step. Tomas Petricek wrote: You mentioned support for call ...Show All

• Visual Basic Date Problem

  Hi everyone~ I’m stumped on something that I thought would be simple. I’m trying to figure out how to determine if the LastModifiedDate of a file was yesterday. Not 24 hours ago, but simply yesterday. I have a third party program that converts files and moves them to a specific folder. Anything converted and moved after midnight gets a new date in the file name (MM/DD) and continues doing it’s thing. I want to set up an event that will work with only files that were created yesterday, even if they are less than an hour old. I don’t know if I am on the right track, but so far I have one variable (TodaysDate) as 09/03/06, and the file’s DateLastModified (FileDate) as 09/02/06. But now I can’t figure out how ...Show All

• SQL Server Visual C++ 2005 (C++/CLI) - Newbie with ADO

  Hi, I've been working for about 20 years now with databases on other platforms but am at my first step with ADO. I created an application which is drawing as requested different forms on screen using GDI+, eventually DirectX. Now I'm at the stage of saving several infos into a Database. For simplicity, I would like to use a database for which there is no need to install any other components. I thought of using Access Database but I realized that I'm unable to create it except from Microsoft Access which is not installed on my machine...

• Visual Studio 2008 (Pre-release) How to callback from a WCF service to Client

  I am developing a sample in which WCF service is hosted in IIS. In this sample WCF service in turn is also communicating with Workflow. I want to add callback functionality from workflow to client through WCF service. In this sample, I have two interfaces, one of them i am implementing in WCF service itself and another is on clent side. For communication between workflow and WCF service, it is containing one class library with ExternalDataExcahngeService and Serializable attribute. Communication form Client to WCF service to Workflow is fine but the problem is with the communication from Workflow to WCF service to Client. My workflow is calling a method in Class library which is responsible for communication between workflow and WCF ...Show All

• Windows Networking Development Winsock/RPC/SSL/Transport error: 0x90312 [SEC_I_CONTINUE_NEEDED]

  I'm working with WinHTTP. WinHttpTraceCfg tool shows me this messages after calling WinHttpSendRequest function. And then I can't get the internet resource. Does anyone here knows how to fix this error And why it happens Are you seeing this error in the trace file after you enable tracing with WinHttpTraceCfg (WinHttpTraceCfg will not call WinHttpSendRequest on its own). In any case, that could be part of WinHttp establishing the SSL channel. What matters is the error code that you are getting right after WinHttpSendRequest fails - it will contain more info to diagnoze the problem. ...Show All

• Windows Forms Catch all Exceptions

  Hi I have a program with several Forms. What I need is to log all exceptions (save them into a database). Is this possible without having to write a "try{ ... } catch(...) {...}" everywhere (and call a static log-method within the catch-body). Kind Regards It all depends on how you want to handle each exception that has the possibility to ocurr. For example, say you have a processControl and it throws a FileNotFoundException, (wrong exception, but just an example). And you want to display a MessageBox saying to make sure the application is installed, handling everything in main() wouldn't give you that functionality. If I am wrong, yell at me for being too lazy to open up Visual Studio and try. ...Show All
