• Visual C++ Having Trouble with an exception

  Hello to all, I'm having a problem with an exception that keeps coming up when I try to run my program. Is there anything I can do to my code to get rid of this My code compiles fine. First-chance exception at 0x695bffe0 in proj_text_spheres.exe: 0xC0000005: Access violation reading location 0x00454001. Unhandled exception at 0x695bffe0 in proj_text_spheres.exe: 0xC0000005: Access violation reading location 0x00454001. I suspect the source of my problem has to do with a call to fclose. Here's part of my code (I writing an OpenGL program that maps a texture to a sphere): void read_fractal1_image(void) { errno_t err; ...Show All

• Visual C# Determining IIS Options via C#

  Hello. For my work, I'm automating system validation to be performed prior to installations of our software. One of the steps is to verify that certain options like "Common Files," "Internet Information Services Snap-IN", and "World Wide Web Server" are installed. I know how to verify this through Add/Remove Windows Components, yet I'm not sure how, or even if it's possible, to verify such things through the use of C# (which I'm writing the program in). Any help would be greatly appreciated. Hi The following code will help you get the list of services running in OS. From the list you try to ...Show All

• SQL Server Using Charts crashes VS 2005

  I have been creating reports just fine in Report Designer 2005 until I tried to drag a report on an open canvas, new project.  I just used a simple bar chart and tried to drag over 3 fields from my dataset to allow it some information.  When I preview the report VS crashes with an unexpected error.  Is this something anyone has come across when trying to create charts    I assume it is not liking something I did but all I did was drag over 3 fields into the appropriate spots.  The error doesn't tell me anything and when I try to debug, it stalls. I'm not sure what it is, but to resolve I just copied ov ...Show All

• .NET Development High bandwidth usage over TCP Channel w/Binary Formatter

  Hi, I'm looking suggestions for ways to reduce the amount of data our remoting-based (.Net framework 2.0) application is putting on the network. It seems that each call to a remoted, wellknown object puts between 1000-1500 bytes on the wire as overhead (i.e. a call that takes no parameters registers about that much traffic), and the overhead on the return from a call is about the same. All in all, every call over the wire is putting 2 or 3KB on the network. Is this considered normal What have other people seen I used a channel sink to write out the contents of the streams before they are sent over the wire and it looks like there's a ...Show All

• Visual Basic Portbability of Visual Basic application to ASP.NET

  I m designing and developping a visual basic windows forms application. But, in a second step, I want to be able to implement the same solution as a web based application without going through all the coding and developping again.

My application should include forms, data acces, reports.......   Thanks a lot. Sorry, but I haven t created classes yet (weird ahh). So I guess ...Show All

• Visual Studio Tools for Office Create a "Bare" Workbook From VSTO

  In my Excel VSTO project, I would like to provide an "Export" button that would copy and reformat one of my worksheets into a new "bare" workbook. The "bare" workbook would not have any VSTO code behind. So, for example, I could e-mail the workbook to a client, and the client clould see the data without worrying about Dot Net deployment and security issues. Read in the data from the sheet and stream the data out to a file that your user's Excel can read such as a CSV format. Hence it is a bare workbook. ...Show All

• .NET Development When method returns Com Invisible type?

  Hello, What exactly is the behaviour here Marking BarNotForCOM [ComVisible(false)] will result in the ReturnBar() function to be exported as the quivalent of object ReturnBar(). QI on the unknown object will only succeed on IUnknown as thats the only interface you know on that object. Unless you have type information for the object you cant do much with it. If you implement an interface (even through another type lib/assembly) on BarNotForCOM and export it to VB , you could cast the unknown object to this interface. eg: [ ComVisible ( true )] [ ClassInterface ( ClassInterfaceType .AutoDual)] [ Guid ( "2DE8CF85-939B ...Show All

• SQL Server IDENTITY fields

  I have a table with an IDENTITY column for a pkey. I'd like to insert one record into this table and use the generated identity value to insert ~100,000 rows in a second table. I'm sure this is a common scenario. I don't want to pre-generate identity values or anything like that - it seems like this should be a simple task and I'm missing something. I've tried OLE-DB Command tasks with INSERT INTO ....; SELECT SCOPE_IDENTITY() - but there doesn't appear to be a way to retrieve a resultset from the OLE-DB command task. I've also tried a data flow with a lookup for the identity, and then tried to merge the one  ...Show All
