• Windows Forms Windows 98/.Net Framework Problem

  Hi, I have a ClickOnce, VB Express application that is working fine on many clients, except for a client who is stuck in the world of Windows 98. I have uninstalled, rebooted and re-installed .Net Framework 2 several times. The reboots seem clean, but when I attempt to Run the application, the file is downloaded and then Windows asks if I want to Run or Save the file. In either case, Windows attempts to open the file, Prize%20Money[1], but of course there is no application associated for this file. I assume that there is a problem with either Windows 98 or .Net Framework 2, but I don't have clue where to begin. Although, I'd like to tell the client to upgrade his old iron and get Windows XP this is not an option. Thanks for your sugg ...Show All

• Software Development for Windows Vista Installation problem in windows vista

  I am facing problem during installation in vista beta2 OS. Windows installer is throwing error during registration of few dlls. These dlls are marked as "self registered" and are build in VS 2005. Also I have included the dependent vc8 merge modules along with the package. I tried to install in a clean XP SP2 OS. It installed with out any problem. Then I tried to install it in vista beta2(5342 and 5384 builds). It throws error while doing the self registration. After the first error message pops up, I checked the WinSxs folder for the dependent mfc dll. That time it was not installed. I ignored all message and finally able to see the mfc dlls in the WinSxs folder. Assuming next time it will install correctly as already depende ...Show All

• .NET Development Invoke soap method with dynamic parameters

  Hi Is it possible to invoke a SOAP method when the namespace (e.g. http://tempuri.org/), the method name (e.g. HelloWorld) and the method parameters are not known at design time. Thanks A couple of suggestions from another thread here: if you're just experimenting, you can try a tool like Web Service Studio . This tool provides a UI that you can point at a web service and allows you to call methods on it while showing what the soap looks like for the requests and responses. if you don't mind using WCF, you can use DynamicProxy . This will create a proxy for a web service at runtime and allows you to call methods on it. It is possible to implement this library for ASMX, but we don't have sample ...Show All

• SQL Server Moving reports backward from RS2005 to RS2000

  Is there a nice way to get reports from an RS2005 project into an RS2000 project I know this sounds like an odd request but I have built reports in RS2005 that need to be deployed to a server with only 2000 on it. I don't really want to have to go in and re-draw all those reports. Any ideas would be most appreciated! Thanks, Eva ok... I have read your comment in Charlie's article - you entered your sql-statements right in the reports without using stored procedure. Best way for the downsizing-option... If you think about a scenario with stored procedures I think it would be worth thinking about a little "rdl-preparator-dwonsize-application" if you would have to downsize more than 15 r ...Show All

• Software Development for Windows Vista Can I avoid serialization problems by going code-only

  Hi I am trying to consider which authoring mode to use for designing workflows. We will only be providing compiled workflow types to the runtime and we will be designing workflows with the default worklfow designer in visual studio. Reading one of the posts on this forum there seems to be some limitations with the code-seperation approach in regard to serializing generic types. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=875768&SiteID=1 . In our scenario would we be able to avoid these serialization problems if we went with the code-only approach Cheers Duncan In most cases using the code only workflow would keep you from getting serialization errors but not all.

• Architecture SOA - Transaction/compensation/cordination

  I have a challange. I have multiple services that are located on different server setups. They are build stateless N-tier architectures based on single call remoting. The services do not support the flow of transactions. This would also couple the services an go against the very idea of service orientation. But ..nevertheless, one needs to perform business operations that span multiple services. How do I best support this. Should I have the programmers do custom compensation code very time (clean-up) and accept that if something crashes the data is inconsistant or should I try to find/implement some kind of common cordination What are my choices Hi Siteadm, As you ...Show All

• Visual C# Getting the console AND GUI to appear simultaneously

  Hello Everyone, I have Just moved over to C# from Java... When I ran Java programs with a GUI from an IDE both the GUI and the console window appeared, so I was able to send debugging information from the GUI program out theough the command line. How is this done when using Visual Studio (Using C# as the programming language). Thank you Chris Hi all, I'm sotred for VS2005. But I'm still having trouble with doing this in VS2003.

• Visual Basic Find And Replace Command Not Working?

  Good day! My Find/Replace Edit Menu command inside VB 2005 is not working anymore, and SQL Server 2005 as well. When I tried to check this feature in Microsoft Office applications, there is no problem at all. It's mysterious, I don't know what happen. I also tried to re-install VB and SQL, but still it didn't work. I know it is a petty problem, but it plays an important role when editing your codes. Please help. Thanks Hi there. I had also posted this problem earlier...found the answer on a different forum. I've had this happen in all visual studio 2005 apps. What seems to be happening is that the find/replace window is there, it's just 'almost' hidden. Drove me nuts. Look around the very edges ...Show All

• Visual Basic Other Apps give my App a "HungApp"

  My application hangs when it has been minimized for a somewhat long period of time (one hour or so). This is especially noticed when another application is running on top of it and has been evidenced on XP, 2k, and 2k3 Server. Some of the specific applications that are causing my grief are SQL Server Mgmt Studio and Novell's GroupWise client.
