• Visual C++ Embed Internet Explorer into another window

  I need to embed an Internet Explorer browser into the application I am developing (I’ll call it myApp). The embed IE browser should not have a Navigation Bar. The IE browser should run inside myApp’s main window. The application is not currently MFC and trying to change it to MFC will take a lot of time and debugging. I used the CreateProcess() functionality, but this will open a IE window that runs in the Desktop, outside myApp’s window. I’ve trying to use OleCreate() but I can’t get it to work because I am not sure how to define the REFIID and ppvObject parameters. Probably there are other parameters that need to be defined and/or obtained. I’ve been looking for a good C++ Code Example but after a coupl ...Show All

• Visual Studio Express Editions How to search text in a file?

  How to search a word in a text file and after that to get the line that contains that word. Regex is expensive to use and should really only be used when you are doing a constant search on specific words or patterns   however as suggested, you can use the indexOf method to check the value exists. example:   .. string currentLine = theStreamReader.ReadLine(); if (currentLine.IndexOf(someString) != -1) {    //do stuff }   ...Show All

• Visual Studio Express Editions How to view instantiated template source code?

  I'm learning about templates. I understand what's going on with them, but I would very much like to see the instantiated source code. This should be the source code with all the actual parameters substituted for the formal parameters. I'd be happy seeing the instantiated code in a listing. How do I see that I'm using VC++ 2005 express under Win2K. Many thanks. Hi I was reading the postings. I have just created a template Node and List class for some homework. It works well but I am not able to step into the list's assignment operator. The program appears to copy one list to another correctly. The reason I may not be able to hit any breakpoints in my template class List may be because of what ...Show All

• Visual Studio Team System Replication vs Proxy Server?

  My company is currently in the process of bringing other branches of our company on to Team Foundation Server (TFS). Our primary offices are in the United States but we have other branches in Europe. Originally we were planning on having a central TFS server in the USA that all branches would connect to. Due to latency and somewhat frequent WAN outages between the branches we are now looking for other options. The first thought we had was to install a second TFS server in our European branch and setup SQL 2005 replication between the two databases. The hope is to have the European branch connect to the TFS server in Europe and the USA branches connect to the TFS server in the USA. With the hopes that we would have identic ...Show All

• .NET Development help needed in pixel operation

  hi, I want to know the difference of the below, 1. Doing image operation with the manipulation of getPixel() and setPixel() methods. 2. getting the address of the first pixel data in the bitmap using the code, BitmapData bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb); int stride = bmData.Stride; System.IntPtr Scan0 = bmData.Scan0; How these two differ thanks in advance.

• Visual Studio 2008 (Pre-release) AddNewRow behaviour with bound ItemsControl

  I'm trying to figure out how to implement AddNewRow functionality to an ItemsControl bound to a DataTable. The simple answer would be to just call DataTable.NewRow followed by DataTable.Rows.Add but that requires all non-null columns to be pre-populated. I'd like to create the same behaviour seen in SQLServer Mangement Studio when adding records to a table. The last item in the ItemsControl should show an empty template. When the user makes the first change, a new empty item template is added underneath the current one. When the user has finished editing the current item it is validated and all constraints checked before adding to the DataTable. The only way I can think of doing this at the moment is to not use databinding but man ...Show All

• SQL Server Restore database on different domain - performance

  Hi, I'm trying to restore database on the server in the different domain. The destination server is located in the physically remoted place. First I tried UNC path (including IP address) with DBCC TRACEON | OFF (1807) optioin but it didn't work. Some Internet document suggested that the FTP file transfer & restore locally on the remote domain but I didn't use this method because there is additional step. Instead I used the following scripts: DECLARE @COMMANDLINE VARCHAR(500) SET @COMMANDLINE = 'NET USE B: \\192.168.1.xxx\sql_backup$ password /USER:SourceServer\read_sql_backup /YES' EXEC master..xp_cmdshell @COMMANDLINE RESTORE DATABASE [DestinationDB] FROM DISK = N'B:\SourceBackup.bak' WITH FILE = 1, NOUNLOAD ...Show All

• Visual C# operator overloading vs operator overriding

  what is the difference between operator overloading and operator overriding thanks in advance for ur replies Overloading vs. overriding is the same, in general, as it is for methods. Overriding is the process of redefining a method (or operator) in a derived class with the same signature as a member in the base class but performing different work. You use overriding all the time. For example when you create a form in a WinForms app you normally override the base Form.OnLoad method with your own. Overloading is the process of defining several methods (or operators) with the same name but different signatures (a signature being the method name and its arguments). Whenever you type an overloaded method's ...Show All

• SQL Server TimeSpan .Net type in AS Stored proc for Elapsed time + ProClarity

  Hi, I guess ,this is kind of an old problem. But I have tried various ways to do this in vain. Here is the scenario: and all the different approaches that I followed I need to convert seconds to DD:HH:MM:SS as elapsed time. it would mean days:hours:minutes:seconds. calculation gives 86400 seconds = 01:00:00:00 (1 day). The elapsed time needs to show negative elapsed time. for example: -02:22:10:05. Also I need to display the same on ProClarity graphs. The graphs also need to show the same dd:hh:mm:ss format. Approach 1: I used the TimeSerial function, this works fine only for HH:MM:SS. It does not support days. also it does not support negative values. Approach 2: I used a custom .Net library (AS stored procedure) which would ...Show All
