• Windows Forms Drawing a control over custom control's boundary

  Hi, I am creating a custom Bread Crumb-type control, and am running into a little bit of a problem when trying to add an intellisense-type functionality to it. The control is pretty much a textbox, but I want a list box to display below it when the user types something in, similar to how VS.NET does it. However, since the listbox's boundary is actually outside the boundary of my control, it cuts it off and I don't see it. Is there any way to "override" this and make Windows draw it regardless Thanks, Yaron The only way I know of getting around this is to create a bordeless form with the list box that pops u ...Show All

• SQL Server One dataflow for sevral Oracle Instances ?

  Hi, I designed a dataflow which extracts, transforms and load (the main goals of an ETL .... ) data from an Oracle db to an Sql Server 2005 db.

• Visual C++ Error converting double to unsigned __int64

  I'm seeing a problem in converting a double to an unsigned __int64. If the double is greater than the maximum for a signed __int64, the conversion returns the wrong value. For example: { double d; unsigned __int64 num = 0xa000000000000000; printf("unsigned __int64 = %#I64x\n",num); d = (double)num; printf("To double = %e\n",d); num = (unsigned __int64)d; printf("From double = %#I64x\n\n",num); } Produces: unsigned __int64 = 0xa000000000000000 // Correct To double = 1.152922e+019 // Correct From double = 0x8000000000000000 // WRONG Is there a fix for th ...Show All

• Visual Studio How do you Use Advantage StreamlineSQL ODBC with CR.NET

  I've created a VS 2003 ASP.NET application that displays crystal reports. I've got it set up so that it is able to display any Report that is using a SQL Server ODBC.  But just recently I've been asked to have a Report which accesses the database though a Advantage StreamlineSQL ODBC and it's not working. a SQL ODBC asks for ODBC name, Servername, database, and login information. StreamineSQL asks for "ODBC name", "table type" (foxpro), and "Database or Data Dictionary Path" (u:\servername\path\) This report works fine using the Crystal Reports 11 application.  But when I try to put it through the ASP.NET application it asks for lo ...Show All

• .NET Development What steps will be need to move a beta project into the final version

  I am wondering if it would be safe to install a solution written in the beta and when the final .net framework comes out what would I have to do to update the installs. Will the autoupdate features of one-click download the updated framework or will the app have to be uninstalled and setup rerun again.     You will need to recompile the application using the final version of the software. Based on changes that are made from the Beta to final version, you may need to make a few code based changes as well - although Microsoft has promised that this would be minimal. Beta 2 comes with a Go Live! Li ...Show All
