• Visual C++ Passing Unmanaged Class by reference to Managed Class Constructor

  I have a MainForm. It has two child forms. The program reads in large SEGY files (2gb -> 100gb), appropiate data and read settings are stored through the class system that has a main controller "SEGY.H" & "SEGY.CPP". They a coded in pure C++. My two child forms are managed. I want to pass a reference for SEGY from the MainForm to each child form when they are required to be shown to the user, obviously to avoid copying large amounts of memory.   I cannot pass a native class by reference to a managed class through the managed classes constructor.  I have tried (code in mainform): private: SEGY *Segy;        //it then gets constructor call when filename is chose CHILDFO ...Show All

• Visual Basic How do I completely unload a form?

  Hi all, I have a form that I use to get the user to input such as a username and password in order to make a network connection. This connection can be disconnected and reconnected as many times as neccessary whilst the application continues to run. I obviously, therefore, need the form's text boxes, combo boxes etc to reset to their blank versions every time that the form is shown. In VB6 this was easy; you just unload the form which completely removed the form from memory and thus the next time you showed it it was reset to it's blank state. In VB 2005, however, there is no unload so we have to use Close. I have done this and assumed that it would function in the same was that unload did in VB6. The problem is that when I c ...Show All

• Windows Forms How do you use UseWaitCursor = true ?

  Hi, Idiot's guide required. Just how is that UseWaitCursor property supposed to work - or rather, why does it appear to do nothing I have a button click handler, it sets "this.UseWaitCursor" to true, and goes and instanciates a DLL hosted dialogue form with a biggo constructor. It takes a while. Nothing happens to the mouse pointer, which is still an arrow. I changed my code to use "this.Cursor = Cursors.WaitCursor" (like we always used to do guys !) and it's markedly better. I searched the net and this question appears in a number of places, with various plausible (but non-working) solutions, but there must be a reason why this doesn't appear to be as simple as it looks. Yes I did try Application.DoEvents (which, person ...Show All

• SQL Server Unique Scenario

  Hi, I am faced with a scenario where I have to predict the time period that will required to solve a particular problem depending on various factors like Problem Type, Severity Level, Resource Availability etc. I would like to know which algorithm is best suited for the above scenario and the reasons for the same. Decision (Regression) Trees or Neural Nets should work for this problem. Both predict continuous values based on either continuous or discrete inputs. You should split your data into training and test sets and try each of them to see which predicts better. ...Show All

• SQL Server Error on Associative Rules Viewer

  Hello, I don't know if this is the correct forum or if it would perhaps be the server setup & upgrade, however, I'll ask here first. I am going through the SQL 2005 data mining tutorials and have encountered an error that states: Query (1,6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[AssociationRules].[GetStatistics]' function does not exist. After looking around for a bit it appeared that this function is generally used in a stored procedure run from the server. Is this correct What do I need to do to either correctly import the function into the project or to make sure that it is installed on the server We are running the Ent Ed. now, however, we just upgraded to this after I had already starte ...Show All

• Windows Forms error trying to publish from vs2005

  I try to publish my application using VS2005, and below is the warnings I receive in the IDE.. Warning 1 Files could not be downloaded from http://dnbl291/TestForm/ . The remote server returned an error: (404) Not Found. 1 1 TestForm Warning 2 Unable to view published application at http://dnbl291/TestForm/publish.htm . 1 1 TestForm The problem for me was that I was not using the Fully qualified domain name of the server. ie server.domain.net etc so it was trying to go through the proxy server therefore the problem. Make sure you use the FQDN, and ensure you don't have to use the proxy. If you are forced to go through a proxy server you have a bigger issue.. ...Show All

• Windows Forms Runtime loaded controls

  Hi everybody, I created a usercontrol witch contains a richtextbox (not only) where the height of that control Depends on the content of the richtextbox, bind to a table of a dataset. So each usercontol displays a row from the table as list in a groupbox with a vertical-scrollbar And I’m fine with that. But my problem is now, because the table could be a really big one – so I can’t bind them all at once, how to get the information when the usercontrol leaves the visible area of the groupbox. (I don’t want to use a 2. scrollbar to skip may be 10 usercontrols like pages at the time) Thanx a lot for hints ...Show All
