instance failure appears wen u have created an object for a class that instantiated it during run time. that is check ur classes for which u created objects and see with which object u have accessed the action of login form.
Best way to do this is to place label and textbox as usual but hide them from the properties.
In the SaveButton Click event, you can set the property for the label and textbox to visible dynamically by code.
You can open the Crystal Report (should be installed with Visual Studio first) after you designed your database, then you have to connect the Crystal Report to the right database (the one which you store financial information in your case), then you can create your report easily by putting the desired variables and designs. Then you have to call for that report with a code within visual basic.
All Depends on your requirement. First you have choose your programming language, then complexity of project. if you for .Net then you have 2 options. If you want to go for Internet Application then go for Asp.Net and if you want to go for Window application then go for C#.Net. But top of all 1) you have to specify your functionality. 2) Create DFD (Data Flow Diagram) 3) ERD (entitiy relationship diagram) 4) create database.
about the dynamic forms/pages, u can use sessions in asp.net C#, theyre very easy to use and try using commands like server.transfer and respond.redirect in ur code. for the connectivity thigee u asked, :) m sorry my friend u cant get it like a pan cake, u gotta study w3schools odbc connectivity in asp.net tag for this :P
If you are running two versions of ASP.NET, you may get HTTP:/1.1 500 Internal Server Error when creating a new Web project or opening an existing Web project in Visual Studio. This problem may occur when IIS is not sure what version of ASP.NET to use or where to locate ASP.NET files. One of the following solutions should fix the problem. Solution 1.
Remove web.config file from inetpub/wwwroot directory
Go to IIS, Right click on Default web site / All tasks / Check server extensions and let it run
Reset IIS by right click on IIS or call iisreset from Run command
Install ASP.NET again using the following command from your Run command: C:WINNTMicrosoft.NETFrameworkv1.1.4322aspnet_regiis.exe Make sure to change the windows folder and ASP.NET version folder with the version what you want to install
Solution 3. Applies to Windows Server 2003 Note: This is a Microsoft KB article: When you try to create a new Microsoft ASP.NET 1.1 application after you change the script mapping of the existing ASP.NET 1.1 Web application to ASP.NET 1.0 on a Microsoft Windows Server 2003-based computer, you may receive the following error message: The Web server reported the following error when attempting to create or open the Web project located at the following URL: 'http://localhost/822319ev1'. 'HTTP/1.1 500 Internal Server Error'. CAUSE This issue occurs because Windows Server 2003 does not allow two versions of ASP.NET to run in the same application pool. WORKAROUND To work around the problem, do one of the following: Restart the IIS before you create a new ASP.NET 1.1 application. At the command prompt type the following command: iisreset OR - Create an ASP.NET application in a separate application pool. Create the script-mapped application (ASP.NET 1.0) in a separate application pool -- for example, in the ScriptMapappPool application pool. Then, create a new ASP.NET 1.1 application in an application pool other than ScriptMapappPool. For more information about how to create an application pool, visit the following Microsoft Web site: Configuring Application Pools http://msdn.microsoft.com/en-us/library/1kdfe21k(VS.80).aspx
Saang, It is a really bad idea to use Office Automation on a web server, your application will not be scalable and will be full of problems. Trust me, I have already spent hundreds of dollars with Microsoft Tech support for this very thing. I code commercial applications for a living, best thing to do is buy an application that creates office documents for you easily through asp.net. I have used a product from Aspose and it has done great. You can download a free trial to check it out. http://www.aspose.com/categories/ssrs-rendering-extensions/aspose.words-for-reporting-services/default.aspx It will save you lots of time coding as well, because they make it very easy to customize your documents. Hope this helps!
