• Windows Forms Textbox default value

  Is it possible to put a textbox on a form, set its default value to 0 then Change it in code and keep the new number, even after the app is closed I know I can change the default value of a textbox by code, but is there a way to keep your changes permanently Davids Learning You may want to look into using My.Settings to save the value when it is changed (or the form is closed) and then to read from on startup of the form to retrieve the saved value. ...Show All

• .NET Development D

  We are upgrading a program from VS03/Sql MSDE to VS Professional 05/SQL 05 Express Edition (SQL Server 2005 Express Edition With Advanced Services SP1 to be exact). The VB code converted fine, but the data has been a disaster. We have tried this with/and without the 05 SP1 Beta and have the same problem. In the 03 IDE, we created many Data Adapters in the Component Designer (just called Component in 05) with multiple tables. In 03 everything worked. In 05, when you configure the existing data adapter, if there is more that one table, you get the error: Dynamic SQL generation is not supported against multiple base tables. and the data adapter is useless. If this is not supported in 05, what do we d ...Show All

• Visual Studio Express Editions Convert decimal to fraction

  Does VB have any built-in function to convert a decimal number to a fraction What I need is a way to convert a decimal number into a fraction string rounded to the nearest 32nd. So for example, .375 would be converted to "3/8" or .428 would be converted to "7/16" after rounding. If VB doesn't have this built-in, does anyone have code for a function to do this Thanks...

• Visual C++ <windows.h> Interferes with System::IO::Directory::GetCurrentDirectory();

  Including windows.h in a managed project overrides System::IO::Directory::GetCurrentDirectory();, which is very annoying: rootFolder = System::IO::Directory::GetCurrentDirectory(); //'GetCurrentDirectoryW' : is not a member of 'System::IO::Directory' How can this be prevented This seems to be the only function in wondows.h that gets confused with System::... If you do not need the GetCurrentDirectory function from windows.h , maybe you can just un-define it: #include <windows.h> #undef GetCurrentDirectory I hope this makes sense. ...Show All

• Visual Studio Maintaining data session state in the CrystalReportViewer

  I finally got a .NET DLL datasource to work for my crystal report. Now I'm wondering if I'm fighting with an 'easier way, that may be already built into Crystal Reports. I've included two routines 1) Page Load - This routine checks the user's ID from Windows which is an NUID, it then takes that NUID to find that user in an Admin table, a Supervisor Table, to decide what type of data should be in the dataset of the report. The routines are nicely streamlined and are based off of stored procedures. Depending on the rank of the person's NUID, that person will see more 'Training status's of various employees. The idea is to have the page automatically display what is valid to that person when they open the page on our intranet. 2) ...Show All

• .NET Development .Net 1.1 forward compatibility

  Hi I have an C# application compiled with VS 2003 (.Net 1.1) that needs to use a dll compiled with VS 2005 (.Net) 2.0. The machine have both runtimes installed but the application refuses to use the dll since it been created by newer version. Is there any way to work in VS 2003 with .Net 2.0 dll's Thanks. Michael, The metadata format of assemblies changed between 1.1 and 2.0 (in order to support generics). The compiler needs to understand this new format, which is one of the reasons that it's not possible to forward target 2.0 with 1.1. As Mattias suggests it may be possible to dynamically load the assembly assuming that the application is running on the 2.0 CLR; however, if the machine that the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Could C# be the future of gaming?

  Since XNA is using C#, and is is a more intuitive language than C++, is it possible that in the future that C# will dominate, espessially in AAA titles. Could XNA be ushering a new way of programming in the main stream I think people underestimate the performance of managed code. There are not many scenarios where unmanaged code will significantly out perform managed code.   When people start to better understand how the garbage collector works and ensure that objects stay small and prevent them from getting promoted to generation 1 and 2 it will make a big performance increase. From what I understand the GC on 360 is the same as in the compact framework, so I’ll have to read up on the differences.   If you lo ...Show All
