• Visual Studio Express Editions Where was the ojbect created?

  Hi all, I am a new guy in MFC, There is a code like this. class CScriptDemoDlg : public CDialog { protected: CScriptObject m_ScriptObj; } CScriptDemoDlg is the Dialog class, it uses CScriptObject. But when i search the whole project , i can't find the place where m_ScriptObj was initialized. Don't we need initialize it or..... Thanks for your reply. You don't need to initialize it because it's not a pointer and it has a parameterless constructor (because otherwise the code would not compile) which is called when the CScriptDemoDlg object that contains it is created. ...Show All

• SQL Server Installing SQL Server 2005, Detecting Installed IIS

  When trying to install SQL 2005, the installation halts at "Detecting Installed IIS". From a previous forum discussion I tried disabling Norton Anti-Virus and Firewall, but the install still does not get past this point. Please help. I did get SQL 2005 installed! After Sam looked at the log files and could not find anything out of the norm, I made sure my machine met the requirements. With that I reinstalled .Net 2.0 and removed .Net 1.1 from my machine. Whether it was the reinstall of 2.0 or the removal of .Net 1.1; the install went without a hitch. I also did disable my firewall and anti-virus for the install. ...Show All

• Visual Basic Convert a string to decimal (where punctation is [,] instead of [.])

  I am converting a string to a single, but I don't get the expected results when converting a string where the punctation mark for the decimal is comma. lets say the text is 6.5 Dim sngMyNumber As Single sngMyNumber = CSng(txtInputA.text) The result is the single number 6.5 .. SUCCESS :) But when the text is 6,5 (which would be a common punctation mark for my application) Dim sngMyNumber As Single sngMyNumber = CSng(txtInputA.text) The result is 65.0 and not 6.5 which I expect. Is there any way to instruct VB to handle [,] in the same way as [.] when converting strings to numbers I could of course handle the string before conversion, and replace any [,] with [.]. Before I do this, I'd like to know if there is any 'standard' wa ...Show All

• Software Development for Windows Vista Get MPEG2Demultiplexer PID Info in C#

  This is my first post here so I hope i'm doing everything correctly. I have a BDA DVB-t app that i'm working on. i am adding a second MPEG2Demultiplexer via an InfTee. I add a Multiplexer and a dump filter to be able to record. I have created the Video and Audio pins and am able to use MAPPID for the pins. I have looked everywhere for information on how to get the current Video and Audio PID info from the first MPEG2Demultiplexer so as to map the second but have only found C++ info. they use QueryInterface i believe but i'm not sure what the equivelant is in C#. or is there another way in C#. I have also used the PSIParser filter connected to a third MPEG2Demultiplexer without success. Any help would be great. Have you lo ...Show All

• Visual C# Accessing an array from an event handler

  Hi, I am working on a project with wav files at the minute. I want to use a radio button so that when you click the button the next sound file is selected from the array and played after a 1 second pause. I can get the sound files to play from load or when i have a button and specifically hard code the file address but i would like to use the array to get the file locations. The code is as below: I set up the array putting values in wavfiles[6 ] = elemds.Tables[3].Rows[i ].ItemArray[3].ToString().Replace("\\", "\\\\"); and then on the radio button click i thought i could use  private void radioButton1_CheckedChanged(object sender, EventArgs e)         {          ...Show All

• SQL Server Transaction log growth during Maintenance Plans

  During my maintenance plans every night, my transaction log for a 17GB database grows to about 9.5GB. I am running transaction log backups every 2 hours, and my transaction log stays around 300MB during the day. However, every night when the optimization job runs, this explosive growth occurs. I have the optimizations set to Reorganize data and index pages, changing free space to 10%, and remove unused space from database files to 10%, shrinking when they grow beyond 50MB. This database handles cash register operations which are not active during the maintenance plan. Hi adgross , I got the same problem as u. I have no idea how to get rid of this. Besides, I can't even change the FULL recovery mode ...Show All

• Visual Studio Tools for Office Serialise Building Blocks and 'load' them while 'online'

  Visual Studio in conjunction with Word 2007 gives great opportunities to automate building of documents from XML 'components', but it all seems only possible 'offline', i.e. when the document is closed. I would like to get XML fed into the document (or attached template) while it is open, for example, to update not just content, but also the structure of the document at a user's request, interactively, for when a brand new disclaimer is developed and the user decides to adopt it. Currently, XML properties are read only at runtime and building blocks can only be .Added from ranges (i.e. 'recorded like old autotexts). Can anyone please correct me if I'm wrong or let me know of a possible solution Thanks so much for any help! ...Show All

• SQL Server How to connect to Analysis Services with Excel 2007 Data Mining Add In?

  I downloaded a trial version of office 2007 and the data mining addin. I do not have an automatic connection to Analysis Services, so most functionality does not work. Is it possible to configure a connection with a trial version If so, does anyone know what the server name is and how to configure it There are a few possible reasons: - is SQL Server Analysis Services 2005 running on the local machine (run "services.msc" from a command prompt and look for a services named "SQL Server Analysis Services") - is AS running as the default instance or as a named instance In services.msc, a default instance would appear as "SQL Server Analysis Services(MSSQLSERVER)" A na ...Show All
