• Architecture Documenting a web site

  I have been given the assignment of documenting the entire site's navigation. They also want to see how and for what reason we would go to each page. I.e.., I need to add an event to an order. So I need to somehow display the interactions of each page to go through a process. This could entail several pages. So I thought that I could do Use Cases for this. My thinking was with Use Cases and Sequence Diagrams I could show the thought patterns to get from point A to point B. My boss tells me today they want to the site map(pages) and then something else to dictate different scenarios. My company is not very good at reading UML. In fact one other person bought UML in 24 hours. I however have read the entire OMG specifications, ...Show All

• Internet Explorer Development FOR GOD'S SAKE, UNINSTALL!!!

  I tried to uninstall so I could install Beta 3, then I got frustrated and just wanted to uninstall, but no luck. Now, I try install RC1, and get a message that it can't uninstall the previous version. I tried the "cheats" where it gave you the filenames to type in, but I don't have any of those files. I like IE7 and would eventually like to get the "real" version, but it seems hopeless at this point, unless I want to have two versions working at the same time. The message I got said "Do you want to install another version (which will also not be able to be removed) " HELP!! Please don't give me the standard link to the support site again. It's been 4 or 5 months and I have not seen an answer to this problem ...Show All

• .NET Development Odd result looping through a collection

  Hello, I am writing a windows app in c#, until yesterday, was working in 1.1 framework on vs 2003. Installed vs 2005 and installed framework 3.0 and 2.0. At one point in the program, I iterate through a custom control collection to dispose all instances of it in a panel. It worked fine before, but now, it only disposes of every other instance. loop: for ( int i = 0; i < imagePanel.Controls.Count; i++) { if (imagePanel.Controls .GetType().ToString().EndsWith( "History" )) { (( History )imagePanel.Controls ).Dispose(); } // close if (imagePanel.Controls .GetType().ToString().EndsWith("History")) } // close for (int i = 0; i < imagePanel.Controls.Count; i++) Anyone else run int ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Timers in Beta2 ?

  In Beta 1, the Game class had some properties that measured time. However, in Beta 2, there appears to only be a GameTime struct passed into Update. If I need a timer for other reasons, such as performance profiling, or for sub-frame measurements, what should I do I can P/Invoke the performance counters, but that's not Xbox compliant. The documentation has nada on "timer" and no static functions on GameTime et al. (It'd be nice if GameTime had a static accessor that returned a gametime, without messing up the "elapsed" part for the next call to update). I thought I remember seeing something in one of the PowerPoint presentations from either GDC or GameFest with a number that was very close to the clock speed of ...Show All

• .NET Development Error Launching the Framework MDbg debugger

  I am having some difficulties with the Mdbg sample debugger so I thought I would try the Framework version MDbg.exe. 1. I launch MDbg.exe from a command prompt 2. Issue an "echo hello world" command 3. Works fine. 4. If I execute the following fragment then I can Issue the echo command and it works.

If I execute the following fragment in which I pass the command arguments then it ends with "the system can not find the specified file" exception.

• Visual Studio Express Editions Sending Iformation?

  Is there a way to send information from one computer to another, not counting using an email code yes there is. you are talking about networking communication in this case. You would need to have a client-server application or just a client connecting to the server, that is if you know how to talk to the computer/application on the other end. you need to look at the TCPClient, TCPListener and perhaps NetworkStream classes: http://msdn2.microsoft.com/en-us/library/1612451t.aspx http://msdn2.microsoft.com/en-us/library/system.net.sockets.tcplistener.aspx http://msdn2.microsoft.com/en-us/library/system.net.sockets.networkstream.aspx Examples are in there on how to achieve what you maybe wanting.

• Visual Studio Tools for Office Question: VSTO2005 + ASP.NET + Excel XP

  I have a question about VSTO 2005 + ASP.NET(C#) + Excel Actually I just want to: 1. Get data from DB 2. Put (better like "CopyFromRecordSet" back in ADODB) the resulted DataTable to Excel 3. (If no Excel automation needed) Change something like Excel Column width, borders... 4. Save the file on server 5. Allow download by user 6. Users open the Excel file by EXCEL 2000, XP I want to use VSTO's ability to change the data directly without touching Excel (no need to install Excel on server) , that way I can't have Step 3 As I know...(maybe wrong)...the VSTO approach needs Excel 2003 to bind the Data Island and the View when the user opens the document, but I want user to open the file using Excel 2000 or XP, (this is my ma ...Show All

• Windows Forms DateTimePicker focus

  Why is it that when the valuechanged event of the datetimepicker is triggered, its focused is not set to true unlike the other controls like combo boxes etc. I need to check this for i only want to check the values only when user is clicking on the selected date time.thanks Regards Alu I'm getting Focused = true when I change the date in the control itself but false when I use the calendar dropdown. Makes sense, it is a separate window. As a workaround, consider setting a boolean form member to True when you change the date in your code. Then check this member in the ValueChanged event. If it is set to true, you know your code caused the event. When set to false, it can only be the user that changed the value. ...Show All

• SQL Server SSIS Shared Configuration files -SP2 Problem

  Hello, I have several packages that share one configuration file located at a network location. Up until i installed sp2 everything worked fine, but now the packages "loose" the path to the configurationfile.

Anyone with similar problems Any help appriciated. Note: This is not the issue that sp1 solved (for me at least). =) ...Show All

• SQL Server Insidious Bug?

  This looks like a bug to me, can someone verify that this is faulty behavior or tell me why it is proper Two stored procedures are defined, each creates a temporary table of the same name, but with different definitions. Both procedures compile successfully. If procedure Two is executed by itself, errors are produced. Once procedure One has been run, then both procedures succeed. It seems to be an issue of improperly resolving the definition of the temporary table. Thanks drop procedure one go create procedure one as begin create table #salt( a int not null, b int not null, c varchar(100) ) insert #salt values( 1, 1, 'Fred' ) insert #salt values( 1, 2, 'Barney' ) insert #salt values( 1, 3, 'Wilma' ) ...Show All
