• .NET Development How to Sort items in a generic List Collection

  Hi Can anybody tell how to sort the generic list based on more than one column. I'm using fallowing code to sort the Generic List for one column. List<ClassProp> listItem3=new List<ClassProp>(); listItem3.Sort( delegate ( ClassProp p1, ClassProp p2) { return p1.OrderSo.CompareTo(p2.OrderSo); }); The above is for sorting based on only one column,But I need more than one column. How Thanks In advance. How about: listItem3.Sort( delegate ( ClassProp p1, ClassProp p2) { return p1.OrderSo.CompareTo(p2.OrderSo) == 0 p1.SecondColumn.CompareTo(p2.SecondColumn) : p1.OrderSo.CompareTo(p2.OrderSo); }); A sort by a second column makes only sense if the values in the first column ...Show All

• Windows Forms WebBrowser instead of a FileView?

  Has anyone got any links to info on using a webBrowser control as a fileview control. If you're not sure what I mean then spawn a webbrowser control and .Navigate("C:\"). It is the same control used in Explorer/Internet Explorer right I mean it browses files perfectly. It just doesn't seem to be to easy to find the selected files... Yeah, I've seen all of them. ExpTree is the best out there. I have even completely recoded it so suit my one project. I am really interested in seeing an actual implementation of an explorer shellview. Complete with context menu support, drag images etc. The closest I've seen to this is the WebBrowser control. It may only implement the IE view but it's still pretty much the same thin ...Show All

• Visual Basic Read/Write Decimal Value to File Problem

  Hi, I'm having a problem with writing Decimal values to file and reading them back again. For some reason, the last digit is truncated when I read the value back again. Take a look at the following code snippet. Dim Value As Decimal = 0.1234D FileOpen(1, "test.dat" , OpenMode.Binary, OpenAccess.Write, OpenShare.LockReadWrite) FilePut(1, Value) FileClose(1) Value = 0D FileOpen(1, "test.dat" , OpenMode.Binary, OpenAccess.Read, OpenShare.LockReadWrite) FileGet(1, Value) FileClose(1) For some reason, when I read Value back again, it is 0.123 instead of 0.1234. The '4' is truncated off the end. It is not a rounding issue as this is a Decimal type and it truncates any digit off ...Show All

• .NET Development help handling data from the web service!

  Could someone possibly help I have managed to connect to this web service and it is accepting my log on credentials but it returns no data... I suspect i am struggling on that part....now the documentation from the provider states that some addresses may have more than one match(this is a credit search). Therefore when more than one match is found...an address and name picklist is returned for the user to choose one match and this is resubmitted. Once resubmitted it should return name and address as entered(the match) as well as other components of a credit search(on a web form) My problem is processing this picklist...i tried this code but would not work: [code] <%@ Page Language="VB"%> <script runat=" server & ...Show All

• Visual Studio 2008 (Pre-release) Possible odd TreeView bug (sample included)

  Using some custom style with a StyleSelector for my TreeView, I found a really strange bug, more related to ItemContainerGenerator, I think. I had to implement some drag and drop, and it appears that switching (my removing and re-inserting them) two sub-items in a sub-collection of a previously switched item in the parent collection used as ItemsSource for my TreeView lead to some unexpected error : The container passed to StyleSelector.SelectStyle while reinserting the sub-items seems "invalid" ! It isn't related to the TreeView anymore : it isn't able to find ressources and if you try getting its parent ItemsControl, it is now null !

• Microsoft ISV Community Center Forums Scorecard & Sharepoint

  Can anyone help!!!! After deploying scorecards to sharepoint, most users when trying to view the scorecard webpart get the following error: Web Part Error: A Web Part or Web Form Control on this Web Part Page cannot be displayed or imported because it is not registered on this site as safe. In fact the only users to be able to view the scorecards are the two accounts used in the creation of the scorecard - almost everyone else gets the above message.

• Visual Studio ReportViewer Conditional Formatting Anyone?

  Hello, I'm completing an application based on VB2005/SQL2005 Standard using ReportViewer. According to the documentation (see http://msdn2.microsoft.com/en-us/library/ms252095(VS.80).aspx ) conditional formatting is supported. However, when I attempt to implement this, the report text is not formatted, but the color specification text is printed as in "Red", instead of the number printed with red color. I am obviously missing something here - any help is much appreciated. My customer specified conditional formatting in the requirement doc, so it is actually rather important to me... Thanks again!

• Internet Explorer Development IE7 and issue with TrackPopupMenu(Win32) within ActiveX-control

  Hello. I have a trouble with calling win32-function TrackPopupMenu from ActiveX in new Interner Explorer 7 (RC1 and all betas). The situation is: I have some ActiveX-control - "MyPopupMenu".
