• Visual C++ sort of CListCtrl

  Hi. For example, for(i=0; i<n; i++) { ... XXX.InsertItem(0, A); // CListCtrl XXXClass::XXX XXX.SetItemText(0, 1, B); XXX.SetItemText(0, 2, C); XXX.SetItemText(0, 3, D); ... } I could get the result of list, but it's reversed, i.e. last-in first-out. I want like this: A B C D i=0 i=1 i=2 ... What's wrong Sorry for this simple matter... for(i=0; i<n; i++) { ... XXX.InsertItem(0, A); // CListCtrl XXXClass::XXX You may like this to modify to, for(i=0; i<n; i++) { XXX.InsertItem( LVIF_TEXT|LVIF_STATE, i, "A", 0, LVIS_SELECTED, 0, 0); // Initialize the text of the subitems.

• .NET Development How do you work with bits in C#?

  Hi There, I have an application where I need to work with bit strings. My existing code is already written in C# so I'd like to continue with it. So far I haven't had too much finding out how to do things. There's a BitArray Class but it's a little obtuse to use, there's the byte type, but again a little obtuse. When I say obtuse, they're a little hard to initialize and you can't easily print a bit string of 0's and 1's. What I'd really like to be able to do is create a bit array or something similar and use that and be able to deal on the individual bit level. Any way I can do this Or some ideas and examples of working with the classes and data types that are available I guess bool really is a bit and I could make a class that uses bools ...Show All

• SQL Server Nested set show leaves of parent

  Hello, I have the following code which will show all bottom level leaf nodes of the hierachy: SELECT name FROM tree WHERE rgt = lft + 1; I'd like to be able to filter results by a node. For example in a tree such as: Products ReleaseProduct Release1 Release build 1 Release build 2 Release 2 Release 2 build 1 Release 2 build 2 Build Product Build 1 Build 2 If Build 2 is chosen (any node with no children) I'd like to just show the Buuild 2, if ReleaseProduct is chosen Release build 1, Release build 2, Release 2 build 1 and Release 2 build 2 will be shown and if BuildProduct is chosen I'd like to display Build 1, Build 2.

• Community Chat Convert Money value to its Textual Representation

  Code Competition I had answered a post Convert to letter format a number value and provided a response that went counter to the logic of the threads up to that point. The two code examples provided to the poster used enums. I posted with a title Enums make me E-Numb and provided a code sample that use no enumerations. One of the other poster's code sample was .Net but based on a previous process he had written in a non .Net language. He commented that he had run my sample and after 100K operations mine was four second faster. He requested that I add some features to the code and repost so he could retest. I accepted his request and that is what this is...a place to post the code away from the original post so it does not become an OTP fro ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. NoSuitableGraphicsDeviceException was unhandled

  Let me just say at the outset that I know nothing about C# (yet) and am trialing the XNA beta to try and get into it. I do know VB and some C, however. Once I had everything installed, I tried a few example programs including the Spacewar project, but I cannot run any of them. They build fine, but I can't run the .exe, and it crashes and asks if I want to send a report to MS. If I "Start Debugging" instead, I get the error "NoSuitableGraphicsDeviceException was unhandled" on the "this.GameComponents.Add(this.graphics);" line. I have no idea where to even start. Is it my install My PC My hardware The program I'm trying to run Once I know the environment is actually working, I can begin the learning! ...Show All

• SQL Server Help with Variance in MDX Query

  I have the following MDX query. It calculates my measure (Call Count) by County on two different days. I would like my query to only return counties where the difference between day 1 and day 2 is greater than 10% of day 1. In other words I am looking for a variance of greater than 10% select ({[Date].[Date].&[20060901], [Date].[Date].&[20060908]}, {[Measures].[Call Count]}) on columns , [NPA NXX].[By Zip Code].[County]. Members on rows from [CallStats] Thanks, -Darrell You need to use the filter function to filter your counties. Here's an example query in Adventure Works which does roughly the same thing, ie returns all products where Internet Sales Amount is 10% greater in the ...Show All

• Windows Forms DataGridView contextmenu strip issue

  I have a dataGridView whose columns have a contextmenu strip. When a cell is being edited I don't want to display a context menu on right click. I am using contextMenuStrip_opening event to set the options on contextmenu depending on the row that is clicked. Suggestions will be very much appreciated. for for my DGV contextmenustrip, I use the event: dataGridView1.CellMouseDown+=new DataGridViewCellMouseEventHandler(dataGridView1_CellMouseDown); then in that function I determine if it was a right click and where the click was. So you can easily check to see if that cell is in edit mode and then set the DGV's contextMenuStrip: private void dataGridView1_CellMouseDown(object sender, DataGridView ...Show All
