• Hoowah DataFormatString in GridView

  I wonder if someone else is suffering the same problem. I found DataFormatString in GridView not work very well when I try to display currency. In VS 2005 Beta version, it works fine, but after I use stardard version, it never display correct. For example: integer 3 always display like 3.0000 but in the beta version, it display like $3.00 which is what I would like. By the way, I assigned datasource, dataadapter and sqlcommand manually, everything else is good, even date format string works, but currency format just NOT work. Not sure if this is a bug DataFormatString  {0:c2} I had a similair problem with formatting a phone number. To display the text this does work: <% #String .Format( "{0:(###) ###-####}" , Convert.ToI ...Show All

• Adysoft C# program on Windows XP Pro

  Two users of an application I developed have told me that my program does not work properly. Controls are being screwed up, settings don't save, a whole lot of stuff is going wrong. The common link They both use Windows XP Professional. I believe Win XP Pro is the reason why something is wrong, and they both do have .NET Framework 2.0 on their OS, so something with Win XP Pro is causing problems. Why doesn't it work on Win XP Pro > It says clr, so obviously common language runtime, so it doesnt seem as if its a code problem (the code I made)....

• Brombomb How to make Invoice Form

  By using VB.net How I can design Invoice form Belongs Customers Thanks and waiting your replay Well it should be, if it works then it works. There are other ways about inserting data more securely and faster in SQL but I am guessing you do not want this just now. The code you have does 1 task it is meant to do - to update the field of a table with the quantity. you create it the way you wish. To have an invoice form to be printed out, check out the printdocument control in .NET 2.0: http://windowssdk.msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument.aspx The invoice form will of course be populated with the data you wish to be populated with.

• usefulacct Dates in PropertyGrid

  There seems to be a bug with dates properties shown in the PropertyGrid. When the value column of the PropertyGrid is wider than the standard monthview control, the dropdown extends the whole of this width, with the monthview appearing on the left, and a large amount of white space to the right. This doesn't look great. What's curious is that if you look at date property of a control in the properties window of Visual Studio, e.g. the MaxDate of a monthview control, this bug doesn't occur, i.e. the dropdown appears on the right and has a width which matches that of the monthview control that it contains. Any views on how to get this correct behaviour in one's own applications Done ...Show All

• Sorcerer14 .NET Framework 2 adoption - Require it in windows update!?

  Why is it so hard to find information about when .NET Framework 2 will be REQUIRED This is a HUGE concern for me in adopting .NET (and shouldn't it for most people who require their app to be downloaded by the general public ). It turns my nice 3.5mb app and blows it up to a 27mb download. This is ridiculous and is making me reconsidering developing in .NET. Why not then just build it in Java and support all OSes then if you require a framework to be downloaded Come on M$, require it in windows update, or forget about it. At least give us a yes or no answer if it will ever be required. .NET is an OPTIONAL choice, not required within Windows. You can just bundle in the .NET Framework in your inst ...Show All

• jay1_z Cannot get custom action to build in my setup project

  Uggh, This seems like it should be so simple. I've created a Win32 dll, with an exported function as follows: UINT __stdcall Uninstall ( MSIHANDLE hModule ) { /* display's a msg box 4 now */ } Then I created a .def file for the project that defines the export as follows: LIBRARY "UninstallCustomActions.dll" EXPORTS Uninstall This builds fine, and I can use dll explorer tools to examine the exported functions, and mine is there and looking good. However, now I add this project output (I tried adding the dll directly as well) to the installation project, create a custom action for uninstall and select this dll. I set the EntryPoint property to Uninstall, and make sure the InstallerClass property ...Show All
