  • Clone existing structs with different alignment in Visual C++

    - by Crend King
    Is there a way to clone an existing struct with different member alignment in Visual C++? Here is the background: I use an 3rd-party library, which uses several structs. To fill up the structs, I pass the address of the struct instances to some functions. Unfortunately, the functions only returns unaligned buffer, so that data of some members are always wrong. /Zp is out of choice, since it breaks the other parts of the program. I know #pragma pack modifies the alignment of the following struct, but I would like to avoid copying the structs into my code, for the definitions in the library might change in the future. Sample code: test.h: struct am_aligned { BYTE data1[10]; ULONG data2; }; test.cpp: #include "test.h" // typedef alignment(1) struct am_aligned am_unaligned; int APIENTRY wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { char buffer[20] = {}; for (int i = 0; i < sizeof(unaligned_struct); i++) { buffer[i] = i; } am_aligned instance = *(am_aligned*) buffer; return 0; } Consider am_aligned is defined in the library header file. am_unaligned is my custom declaration, and only effective in test.cpp. The commented line does not work of course. instance.data2 is 0x0f0e0d0c, while 0x0d0c0b0a is desired. Thanks for help!

  • Split table and insert with identity link

    - by The King
    Hi.. I have 3 tables similar to the sctructure below CREATE TABLE [dbo].[EmpBasic]( [EmpID] [int] IDENTITY(1,1) NOT NULL Primary Key, [Name] [varchar](50), [Address] [varchar](50) ) CREATE TABLE [dbo].[EmpProject]( [EmpID] [int] NOT NULL primary key, // referencing column with EmpBasic [EmpProject] [varchar](50) ) CREATE TABLE [dbo].[EmpFull_Temp]( [ObjectID] [int] IDENTITY(1,1) NOT NULL Primary Key, [T1Name] [varchar](50) , [T1Address] [varchar](50) , [T1EmpProject] [varchar](50) ) The EmpFull_Temp table has the records with a dummy object ID column... I want to populate the first 2 tables with the records in this table... But with EmpID as a reference between the first 2 tables. I tried this in a stored procedure... Create Table #IDSS (EmpID bigint, objID bigint) Insert into EmpBasic output Inserted.EmpID, EmpFull_Temp.ObjectID into #IDSS Select T1Name, T1Address from EmpFull_Temp Where ObjectID < 106 Insert into EmpProject Select A.EmpID, B.T1EmpProject from #IDSS as A, EmpFull_Temp as B Where A.ObjID = B.ObjectID But it says.. The multi-part identifier "EmpFull_Temp.ObjectID" could not be bound. Could you please help me in achieving this...

  • How to set webview scroll position within it on initial launch ?

    - by mob-king
    I have an issue with Webview to set the initial scroll position within it when first launched. By default it is left , I want it to scroll and show the view from center. Or is it possible to resize the view to fit the screen width initially, instead of scroll bars. I need this since the left part of the page I am loading is blank making user feel the page is not loaded.

  • More memory usage for IIS 6 asp.net 2.0 on webserver 2003

    - by Alan King
    Running a webserver 2003 SP2 (x86) with IIS 6 and asp.net 2. The box is running mostly dynamic asp pages connecting to a sql 2008 server. At any given time there is over 1 gig of memory available out of the 2 gig in the box. It seems like there would be a way for it to make better use of the free memory. It is using a default machine.config file and default http.sys. I would like to maximize incoming internet connections and database connections. Is there something I can do to make better use of the available memory?

  • Using data from a dataset in styles with Mapnik

    - by Alex King
    I've setup Mapnik to connect to a PostGIS database, and display geometry. I'd like to have a column in my database called opacity, and use it as the opacity for that row of geometry when Mapnik renders it. So far, I've only found information on how to display text from the database, and how to use filters to display different styles when database values are within parameters. Nothing about how to use the values directly inside of a style or layer though - is this possible?

  • Validate data before uploading through SSIS

    - by The King
    I have a SSIS package to upload data from Excel file into an Sql Server 2005 table. The excel file will have varied lines of data ranging from 20k - 30k lines. The upload works fine, when all the data are correct. But obviously fails when there is a small problem even in a single row. Examples like mandatory values presented null, inconvertable values (data type mismatch) etc. I want to validate the excel file before the upload and want to tell the user which row and column has got the error... Any idea as to how to accomplish this, without consuming much time and resources. Thanks

  • Strange behaviour on postback in ASP.NET

    - by C-King
    I'm working on a website with a login form. To log in, a postback is used to an OnClick handler in the codebehind. Somehow, the value returned from the Text-property of the username and password textboxes is ten times the value I entered, separated by commas. I checked my entire code for double ID's (which seems to be the most common problem causing this behaviour), but I found each ID defined only once. In the ASPX file I have this: <asp:Label ID="lblFeedback" ForeColor="Red" Font-Bold="true" runat="server" Visible="false" /><br /> <asp:Panel ID="pnlLogin" runat="server"> <table style="border-style: none;"> <tr> <td> <asp:Label ID="lblUsername" AssociatedControlID="txtUsername" runat="server" /> </td> <td> <asp:TextBox ID="txtUsername" runat="server" /><br /> </td> </tr> <tr> <td> <asp:Label ID="lblPassword" AssociatedControlID="txtPassword" runat="server" /> </td> <td> <asp:TextBox ID="txtPassword" runat="server" TextMode="password" /><br /> </td> </tr> <tr> <td> </td> <td> <asp:Button ID="btnLogin" OnClick="btnLogin_Click" runat="server" /> </td> </tr> </table> </asp:Panel> The OnClick handler in the Codebehind: protected void btnLogin_Click(object sender, EventArgs e) { string username = Util.Escape(txtUsername.Text); string password = Util.Escape(txtPassword.Text); WebsiteUser user = WebsiteUser.Create(username, password); if (user != null) { //Set some session variables and redirect to user profile } else { lblFeedback.Text = Localizer.Translate("INVALID_LOGIN"); lblFeedback.ForeColor = Color.Red; lblFeedback.Visible = true; pnlLogin.Visible = true; } } The website is running on ASP.NET 2.0 on ISS 5.1 (Win XP Pro)

  • url or content as a variable in the header of the page

    - by Scorpion King
    I am designing a site where external links form various are being shown on my page. I am using $url=$_GET['url']; $website_data = file_get_contents($url); echo $website_data; so essentially a user would click on a hyperlink which is something like www.test.com/display_page.php?url=http://www.xyz.com/article/2.jpg My page, list_of_images.php, typically has a list of images with href for each image as above on the page and when any image is clicked it would go to display_page.php, which would show our banner on the top of this page, some text and then this image beneath that. This image could be from any website. I am currently sending the url directly and grabbing it using GET. I understand that users/hackers can actually do some coding and send commands for the url variable and could break the server or do something harmful and so i would like to avoid this method or sending the url directly in the header. what is the alternate approach for this problem?

  • Where is the windows app installed + .NET + VS2005

    - by The King
    I deployed a windows application in the following website http://StagingServer/MyProgs/MPP/ on my intranet site, using the Publish Wizard of VS 2005... I accepted all defaults (including Offline support). My users were also able to install the same from the path specified. But when I try to find out the exact location of the EXE in the client, it is not pointing anywhere. I also tried a file search but in vain. Initially I thought the application is running from the server itself, but we were able to start the app, even when the server is down (ofcourse it takes more time to search for updates initially). Ps : The app is showing even in control panel... Raja

  • Table for each region in MySQL

    - by King Wu
    There are four regions with more than one million records total. Should I create a table with a region column or a table for each region and combine them to get the top ranks? If I combine all four regions, none of my columns will be unique so I will need to also add an id column for my primary key. Otherwise, name, accountId & characterId would be candidate keys or should I just add an id column anyways. Table: ---------------------------------------------------------------- | name | accountId | iconId | level | characterId | updateDate | ----------------------------------------------------------------

  • SQL Compact Edition 3.5 SP 1 - LockTimeOutException - how to debug?

    - by Bob King
    Intermittently in our app, we encounter LockTimeoutExceptions being throw from SQL CE. We've recently upgraded to 3.5 SP 1, and a number of them seem to have gone away, but we still do see them occasionally. I'm certain it's a bug in our code (which is multi-threaded) but I haven't been able to pin it down precisely. Does anyone have any good techniques for debugging this problem? The exceptions log like this (there's never a stack trace for these exceptions): SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property. [ Session id = 6,Thread id = 7856,Process id = 10116,Table name = Product,Conflict type = s lock (x blocks),Resource = DDL ] Our database is read-heavy, but does seldom writes, and I think I've got everything protected where it needs to be. EDIT: SQL CE already automatically uses NOLOCK http://msdn.microsoft.com/en-us/library/ms172398(sql.90).aspx

  • git squash and preserve last commit's timestamp

    - by Crend King
    Consider I have commits ... -- A -- B -- C If I use git rebase -i to squash all three commits into one, we could pick A squash B squash C I see the resulted commit A has its original timestamp. How could make it inherit the timestamp of commit C (the last one)? What I can think of is git commit --amend --date=<new_time>, but I need to remember the timestamp of commit C before squash or from reflog. I find the timestamp of the latest timestamp is more reasonable, because it show when do I actually finish the work that are in the commits. Thanks.

  • Objective C instance variables - Newbie

    - by Dwayne King
    OK - so I'm sure my confusion here is just a result of being stuck in a "Java mindset" and not understanding how Obj C differs in this case. In Java, I can declare a variable in a class, like this, and each instance of that class will have it's own: MyClass { String myVar; MyClass() { // constructor } } In Obj C I tried to do the same thing by declaring a variable only in the .m file like this: #import "MyClass.h" @implementation MyClass NSString *testVar; @end My expectation here was that this variable has a scope limited to this class. So I created a second class (identical): #import "MySecondClass.h" @implementation MySecondClass NSString *testVar; @end What I'm seeing (and has me baffled) is that changing the variable in one class, affects the value seen in the other class. In fact, if I set a breakpoint, and then "Jump to Definition" of the variable, it takes me to th I've created an extremely small XCode project that demonstrates the problem here Nothing more humbling than moving to a new language :) Thanks in advance.
